Description

The present invention relates to a straddled vehicle driving data processing device and a straddled vehicle driving data processing method that process driving data related to a straddled vehicle while it is in motion.

Straddled vehicle driving data processing devices have been used in training straddled vehicle drivers or analyzing driving techniques, and process driving data related to a straddled vehicle while it is in motion. For example, the straddled vehicle driving data processing device disclosed in Patent Document 1 acquires trajectory data related to the approach turning trajectory, which is the trajectory of the straddled vehicle, and acceleration data related to the vehicle's forward acceleration when traveling along the approach turning trajectory, and outputs composite driving data correlating the trajectory data and acceleration data. The approach turning trajectory is a trajectory that fits within an area consisting of an approach region between a first line greater than 0 m and less than 65 m in length and a second line parallel to the first line and 2 m away from the first line, and a turning region between a first arc with a central angle of 90° to 270° and a radius of 2 m to 10 m, and a second arc located radially outward of the first arc and 2 m away from the first arc. Because trajectory data related to the approach turning trajectory and acceleration data related to the vehicle's forward acceleration when traveling the approach turning trajectory are data that strongly reflect the rider's driving technique and/or vehicle characteristics, the output composite driving data also strongly reflects the rider's driving technique and/or vehicle characteristics. As a result, the straddled vehicle driving data processing device of Patent Document 1 can reduce the types of data acquired and processed compared to conventional straddled vehicle driving data processing devices that acquire many types of data to output data that strongly reflect the rider's driving technique and/or vehicle characteristics. As a result, the straddled vehicle driving data processing device of Patent Document 1 can improve the design flexibility of hardware resources such as processors and memory compared to conventional straddled vehicle driving data processing devices that acquire many types of data to output data that strongly reflect the rider's driving technique and/or vehicle characteristics.

Straddled vehicle driving data processing devices, which process driving data from straddled vehicles, are required to have greater design freedom in terms of hardware resources.

The present invention aims to provide a straddled vehicle driving data processing device and a straddled vehicle driving data processing method that improve the design flexibility of hardware resources by performing data processing different from that of the straddled vehicle driving data processing device of Patent Document 1.

(1) A straddled vehicle travel data processing device according to one embodiment of the present invention has the following configuration.
A straddled vehicle driving data processing device processes driving data related to a straddled vehicle while it is in motion, the processing device having a processor configured to execute at least the following steps: a data acquisition process to acquire driving data including at least first vehicle-speed-related driving data related to vehicle speed when the straddled vehicle travels through a course having a plurality of J-shaped regions of the same shape and size three to seven consecutive times while a first vehicle speed condition, which is a constraint on vehicle speed, is imposed on the rider during a first period from when the straddled vehicle starts to when it stops; and a data output process to output output data including at least first vehicle-speed-related physical quantity comparison data in a format comparing at least one type of vehicle-speed-related physical quantity related to vehicle speed for each of three to seven consecutive times of traveling through the J-shaped region while the first vehicle speed condition is imposed, based at least on the acquired first vehicle-speed-related driving data.

According to this configuration, the data acquisition process acquires driving data including first vehicle speed-related driving data. The first vehicle speed-related driving data is data related to the vehicle speed when the straddled vehicle travels through a J-shaped region three to seven times consecutively on a course having multiple J-shaped regions of the same shape and size during a predetermined period (first period) from the start to the stop of the straddled vehicle, with a first vehicle speed condition imposed on the rider, which is a restriction on the vehicle speed. In this way, the acquired first vehicle speed-related driving data is data related to the vehicle speed when the straddled vehicle travels under conditions imposed on the vehicle speed and course. By imposing conditions on the vehicle speed and course, the acquired first vehicle speed-related driving data strongly reflects the rider's driving technique. Therefore, it is possible to acquire driving data that strongly reflects the rider's driving technique without acquiring many types of data as driving data.
Furthermore, the output data output in the data output process includes at least first vehicle-speed-related physical quantity comparison data based at least on the acquired first vehicle-speed-related traveling data. The first vehicle-speed-related physical quantity comparison data included in the output data is in a format that compares at least one type of vehicle-speed-related physical quantity related to the vehicle speed for each of three to seven consecutive times traveling through a J-shaped region while the first vehicle speed condition is imposed. Here, if the J-shaped region is traveled more than seven times consecutively while the first vehicle speed condition is imposed, it is difficult for the rider to memorize the traveling sensation of the straddled vehicle for each J-shaped region. Therefore, if data related to vehicle speed when traveling through a J-shaped region more than seven consecutive times while the first vehicle speed condition is imposed is acquired, and the output data includes comparison data in a format comparing at least one type of vehicle-speed-related physical quantity for each of the more than seven consecutive times traveling through the J-shaped region while the first vehicle speed condition is imposed, it is difficult for the rider to ensure consistency between the riding sensation of the straddled vehicle for each J-shaped region that the rider remembers and the at least one type of vehicle-speed-related physical quantity for each J-shaped region in the output data. In contrast, in the present invention, the acquired first vehicle-speed-related riding data is data related to vehicle speed when traveling through a J-shaped region three to seven consecutive times while the first vehicle speed condition is imposed. Also, in the present invention, the output data includes first vehicle-speed-related physical quantity comparison data in a format comparing at least one type of vehicle-speed-related physical quantity for each of the three to seven consecutive times traveling through the J-shaped region while the first vehicle speed condition is imposed. Therefore, it is easy to ensure consistency between the riding sensation of the straddled vehicle for each J-shaped region that the rider remembers and at least one type of vehicle speed-related physical quantity for each J-shaped region in the first vehicle speed-related physical quantity comparison data included in the output data.
Furthermore, if the rider travels through the J-shaped region three or more consecutive times while the first vehicle speed condition is imposed, the rider is given two opportunities to correct his or her driving in the J-shaped region. Therefore, by including first vehicle speed-related physical quantity comparison data in a format that compares at least one type of vehicle speed-related physical quantity for each of three to seven consecutive times of traveling through the J-shaped region while the first vehicle speed condition is imposed, it is possible to confirm, using the output data, how and to what extent the at least one type of vehicle speed-related physical quantity changes as the number of times the J-shaped region is traveled increases. By confirming, from the output data, how and to what extent the at least one type of vehicle speed-related physical quantity changes as the number of times the J-shaped region is traveled increases, it is possible to confirm the rider's driving technique from the perspective of the rider's carefulness. Therefore, it is possible to output output data that more strongly reflects the rider's driving technique without having to acquire and process many types of data. As described above, the straddled vehicle travel data processing device can acquire travel data including first vehicle-speed-related travel data that strongly reflects the rider's driving technique, and output output data including first vehicle-speed-related physical quantity comparison data that strongly reflects the rider's driving technique, without acquiring and processing many types of data. Therefore, compared to a straddled vehicle travel data processing device that acquires and processes many types of data to output data that strongly reflects the rider's driving technique, hardware resources with smaller processing power and memory capacity can be used. As a result, the design flexibility of hardware resources such as the processor and memory of the straddled vehicle travel data processing device can be improved. Therefore, the straddled vehicle travel data processing device of the present invention can improve the design flexibility of hardware resources by processing data differently from the straddled vehicle travel data processing device of Patent Document 1.

(2) In addition to the configuration of (1) above, the straddled vehicle travel data processing device according to one embodiment of the present invention may have the following configuration.
The J-shaped region consists of a linear region and an arc-shaped region connected to the end of the linear region, the width of the J-shaped region is 2 m, the length of the linear region is greater than 0 m and less than 65 m, the radius of the arc of the inner peripheral edge of the arc region is greater than 2 m and less than 10 m, and the central angle of the arc region is greater than 90° and less than 270°.

By having the J-shaped region have the above-described shape and size, it is possible to acquire first vehicle speed-related driving data that more strongly reflects the rider's driving technique. Therefore, the output data includes first vehicle speed-related physical quantity comparison data that more strongly reflects the driving technique, based on the first vehicle speed-related driving data that more strongly reflects the driving technique. Therefore, even if the number of types of data to be processed is small, it is possible to output output data that more strongly reflects the rider's driving technique. This allows for greater flexibility in the design of hardware resources.

(3) In addition to the configuration of (1) or (2) above, the straddled vehicle travel data processing device of one embodiment of the present invention may have the following configuration.
In the data acquisition process, the driving data is acquired that includes at least the first vehicle speed-related driving data and second vehicle speed-related driving data related to the vehicle speed when the J-shaped region is driven three to seven times consecutively during a second period from the start to the stop of the straddled vehicle on the course having the plurality of J-shaped regions of the same shape and size, with a second vehicle speed condition imposed on the rider that is a vehicle speed constraint different from the first vehicle speed condition, and in the data output process, the output data is output that is associated with at least the first vehicle speed-related physical quantity comparison data based at least on the acquired first vehicle speed-related driving data and second vehicle speed-related physical quantity comparison data that compares the at least one type of vehicle speed-related physical quantity related to vehicle speed for each of three to seven consecutive times driving through the J-shaped region with the second vehicle speed condition imposed, based at least on the acquired second vehicle speed-related driving data.

With this configuration, the first vehicle speed-related driving data and second vehicle speed-related driving data acquired in the data acquisition process are data related to the vehicle speed when the straddled vehicle was traveling under different vehicle speed conditions imposed on the rider. Different vehicle speed conditions result in different driving difficulty levels. The output data is data in which at least first vehicle speed-related physical quantity comparison data and second vehicle speed-related physical quantity comparison data are associated, based on the first vehicle speed-related driving data and second vehicle speed-related driving data, respectively, which have different driving difficulty levels. By including first vehicle speed-related physical quantity comparison data and second vehicle speed-related physical quantity comparison data with different driving difficulty levels in the output data, it is possible to output output data that more strongly reflects the rider's driving technique, including their carefulness. Therefore, even if the number of types of data processed is small, it is possible to output output data that more strongly reflects the rider's driving technique. This further improves the design flexibility of hardware resources.

(4) In addition to the configuration of (3) above, the straddled vehicle travel data processing device according to one embodiment of the present invention may have the following configuration.
The first vehicle speed condition and the second vehicle speed condition include different constraints on the acceleration of the straddled vehicle in a vehicle forward direction.

With this configuration, there is a large difference in driving difficulty when traveling through the J-shaped area under the first vehicle speed condition and the second vehicle speed condition. This allows for output data that more strongly reflects the rider's driving technique. Therefore, even if the number of types of data processed is small, it is possible to output output data that more strongly reflects the rider's driving technique. This allows for greater flexibility in the design of hardware resources.

(5) In addition to the configuration of (4) above, the straddled vehicle travel data processing device according to one embodiment of the present invention may have the following configuration.
When the first vehicle speed condition includes suppressing changes in acceleration of the straddled vehicle in the forward direction or increasing changes in acceleration of the straddled vehicle, and the first vehicle speed condition includes suppressing changes in acceleration of the straddled vehicle in the forward direction, the second vehicle speed condition includes increasing changes in acceleration of the straddled vehicle in the forward direction, and when the first vehicle speed condition includes increasing changes in acceleration of the straddled vehicle in the forward direction, the second vehicle speed condition includes suppressing changes in acceleration of the straddled vehicle in the forward direction.

When driving through a J-shaped area to increase the change in forward acceleration of the vehicle, the operation is more complex and the driving difficulty is higher than when driving through a J-shaped area to reduce the change in forward acceleration of the vehicle. Therefore, with the above configuration, the difference in driving difficulty when driving through a J-shaped area under the first vehicle speed condition and the second vehicle speed condition is greater, and the difference in required rider awareness is also greater. As a result, output data that more strongly reflects the rider's driving technique can be output. Therefore, even if the number of types of data processed is smaller, output data that more strongly reflects the rider's driving technique can be output. This further improves the design flexibility of hardware resources.

(6) A straddled vehicle travel data processing device according to one embodiment of the present invention may have the following configuration in addition to any of the configurations (1) to (5) above.
In the data output process, the output data includes at least the first vehicle speed-related physical quantity comparison data in a format in which the at least one type of vehicle speed-related physical quantity for each of three to seven consecutive times of driving in the J-shaped area under the first vehicle speed condition is arranged in chronological order, based at least on the acquired first vehicle speed-related driving data.

This configuration makes it possible to output output data including first vehicle-speed-related physical quantity comparison data that makes it easier to check driving technique in more detail. In other words, it is possible to output output data including first vehicle-speed-related physical quantity comparison data that more strongly reflects the rider's driving technique. Therefore, even if the number of types of data processed is small, it is possible to output output data that more strongly reflects the rider's driving technique. This further improves the design flexibility of hardware resources.

(7) A straddled vehicle travel data processing device according to one embodiment of the present invention may have the following configuration in addition to any of the configurations (1) to (6) above.
In the first vehicle speed-related physical quantity comparison data, the at least one type of vehicle speed-related physical quantity for each of the three to seven consecutive times of traveling through the J-shaped region under the first vehicle speed condition includes a maximum vehicle speed for each J-shaped region, a minimum vehicle speed for each J-shaped region, a maximum positive acceleration of the straddled vehicle in a vehicle forward direction for each J-shaped region, a minimum negative acceleration of the straddled vehicle in a vehicle forward direction for each J-shaped region, a maximum acceleration of the straddled vehicle in a vehicle lateral direction for each J-shaped region, a maximum value of a vehicle speed for each J-shaped region, ... The vehicle acceleration coefficients include at least one of the maximum value of rotational acceleration around an axis along the vehicle vertical direction of the straddled vehicle for each J-shaped region, the maximum value of centrifugal force acting on the straddled vehicle for each J-shaped region, the maximum value of inertial force acting on the straddled vehicle in the vehicle left-right direction for each J-shaped region, the maximum value of lateral force acting on the wheels of the straddled vehicle for each J-shaped region, and the maximum value of the inclination angle of the body frame of the straddled vehicle in the vehicle left-right direction relative to the vehicle up-down direction for each J-shaped region.

This configuration makes it possible to output output data including first vehicle-speed-related physical quantity comparison data that more strongly reflects the rider's driving technique. Therefore, even if the number of types of data processed is small, it is possible to output output data that more strongly reflects the rider's driving technique. This allows for greater flexibility in the design of hardware resources.

(8) A straddled vehicle travel data processing device according to one embodiment of the present invention may have the following configuration in addition to any of the configurations (1) to (7) above.
The at least one type of vehicle speed-related physical quantity is a plurality of types of vehicle speed-related physical quantities, and in the first vehicle speed-related physical quantity comparison data, the plurality of types of vehicle speed-related physical quantities for each of the three to seven consecutive times of traveling through the J-shaped region while the first vehicle speed condition is imposed include at least the maximum value of the inclination angle of the body frame of the straddled vehicle in the vehicle left-right direction relative to the vehicle up-down direction for each of the J-shaped regions.

With this configuration, the first vehicle speed-related physical quantity comparison data included in the output data is in a format that compares multiple types of vehicle speed-related physical quantities for each of three to seven consecutive runs through the J-shaped region while the first vehicle speed condition is imposed. Furthermore, one of the multiple types of vehicle speed-related physical quantities is the maximum value of the tilt angle of the straddled vehicle's body frame in the vehicle's lateral direction relative to the vehicle's vertical direction. This makes it possible to output output data that more strongly reflects the rider's driving technique. Therefore, even if the number of types of data processed is small, it is possible to output output data that more strongly reflects the rider's driving technique. This further improves the design flexibility of hardware resources.

(9) A straddled vehicle travel data processing device according to one embodiment of the present invention may have the following configuration in addition to any of the configurations (1) to (8) above.
In the data acquisition process, the driving data is acquired which includes at least the first vehicle speed-related driving data and first posture-related driving data related to the posture of at least one of the straddled vehicle and the rider when the straddled vehicle travels through the J-shaped region at least three to seven consecutive times while the first vehicle speed condition is imposed on the rider on the course having the plurality of J-shaped regions of the same shape and size during the first period from when the straddled vehicle starts to when it stops; and in the data output process, the output data is output which is at least associated with the first vehicle speed-related physical quantity comparison data based at least on the acquired first vehicle speed-related driving data and first posture-related data related to the posture of at least one of the straddled vehicle and the rider when the straddled vehicle travels through the J-shaped region at least one of the three to seven consecutive times while the first vehicle speed condition is imposed.

With this configuration, the output data includes, in addition to the first vehicle speed-related physical quantity comparison data, first posture-related data related to the posture of at least one of the straddled vehicle and the rider when traveling through the J-shaped region. This makes it possible to output output data that more strongly reflects the rider's driving technique. Therefore, even if the number of types of data processed is small, it is possible to output output data that more strongly reflects the rider's driving technique. This further improves the design flexibility of hardware resources.

(10) A straddled vehicle travel data processing device according to one embodiment of the present invention may have the following configuration in addition to any of the configurations (1) to (9) above.
In the data acquisition process, the driving data is acquired which includes at least the first vehicle speed-related driving data and first trajectory-related driving data related to the trajectory of the straddled vehicle when the straddled vehicle travels through the J-shaped region at least once when the straddled vehicle travels through the J-shaped region three to seven consecutive times while the first vehicle speed condition is imposed on the rider on the course having the plurality of J-shaped regions of the same shape and size during the first period from when the straddled vehicle starts to when it stops; and in the data output process, the output data is output which is at least associated with the first vehicle speed-related physical quantity comparison data based at least on the acquired first vehicle speed-related driving data and first trajectory-related data related to the trajectory of the straddled vehicle when the straddled vehicle travels through the J-shaped region at least once of the three to seven consecutive times while the first vehicle speed condition is imposed.

With this configuration, the output data includes, in addition to the first vehicle speed-related physical quantity comparison data, first trajectory-related data related to the trajectory of the straddled vehicle when traveling through a J-shaped region. This makes it possible to output output data that more strongly reflects the rider's driving technique. Therefore, even if the number of types of data processed is small, it is possible to output output data that more strongly reflects the rider's driving technique. This allows for greater flexibility in the design of hardware resources.

(11) A straddled vehicle driving data processing method according to one embodiment of the present invention has the following configuration. This method is for a straddled vehicle driving data processing device that processes driving data related to a straddled vehicle while it is in motion, and includes at least a data acquisition process that acquires driving data including at least first vehicle-speed-related driving data related to vehicle speed when the straddled vehicle travels through a course having a plurality of J-shaped regions of the same shape and size three to seven consecutive times during a first period from the start to the stop of the straddled vehicle, with a first vehicle speed condition imposed on the rider that is a constraint on vehicle speed; and a data output process that outputs output data including at least first vehicle-speed-related physical quantity comparison data in a format that compares at least one type of vehicle-speed-related physical quantity related to vehicle speed for each of three to seven consecutive times traveling through the J-shaped region under the first vehicle speed condition, based at least on the acquired first vehicle-speed-related driving data.

This configuration achieves the same effects as the straddled vehicle driving data processing device with the configuration (1) above. In other words, this straddled vehicle driving data processing method improves the design flexibility of hardware resources by performing data processing differently from the straddled vehicle driving data processing method of Patent Document 1.

In the present invention and its embodiments, a straddled vehicle refers to a vehicle in general on which a rider (driver) sits astride a saddle. Straddled vehicles may or may not have wheels. Straddled vehicles travel on road surfaces. In this specification, road surfaces include ground, snow, and water. Ground here may be a paved surface or a soiled surface. In the present invention and its embodiments, a straddled vehicle may or may not have a power source (drive source) that generates power for traveling. The power source may be, for example, an electric motor, an engine, or both an electric motor and an engine. In the present invention and its embodiments, a straddled vehicle may be a leaning vehicle having a body frame that leans to the right relative to the vertical direction of the vehicle when turning right and to the left relative to the vertical direction of the vehicle when turning left. In the present invention and its embodiments, a straddled vehicle does not have to be a leaning vehicle.

In the present invention and embodiments, the straddled vehicle driving data processing device may be used, for example, to train or analyze the driving skills of a straddled vehicle rider. The straddled vehicle driving data processing device does not have to be a device mounted on the straddled vehicle. In the present invention and embodiments, the straddled vehicle driving data processing device may be composed of a single device, or may be composed of multiple devices configured to be able to communicate data with each other. In the present invention and embodiments, the straddled vehicle driving data processing device may or may not have the same configuration as the straddled vehicle driving data processing device described in Patent Document 1. For example, in the present invention and embodiments, the output data output in the data output process may include the straddled vehicle driving combined data described in Patent Document 1. The output data in the present invention and embodiments may include the straddled vehicle driving combined data described in International Publication No. 2020/100333.

In the present invention and its embodiments, a processor includes a CPU (Central Processing Unit), GPU (Graphics Processing Unit), microprocessor, multiprocessor, application specific integrated circuit (ASIC), programmable logic circuit (PLC), field programmable gate array (FPGA), and any other circuit capable of performing the processes described herein. In the present invention and its embodiments, a straddled vehicle driving data processing device has a processor and a non-transitory recording medium. The non-transitory recording medium stores a program that causes the processor to perform at least the processes described herein.

In the present invention and embodiments, acquiring driving data including at least first vehicle speed-related driving data in the data acquisition process may mean acquiring driving data including at least the first vehicle speed-related driving data from a device external to the straddled vehicle driving data processing device, or generating and acquiring driving data including at least the first vehicle speed-related driving data based on data acquired from a device external to the straddled vehicle driving data processing device. The definition of acquiring first vehicle speed-related driving data and driving data including data other than the first vehicle speed-related data in the data acquisition process is the same as above.

In the present invention and embodiments, outputting output data in data output processing may mean outputting the output data to a device external to the straddled vehicle driving data processing device. Outputting output data in data output processing may mean outputting the data to a processor possessed by the straddled vehicle driving data processing device that executes at least processing other than the data acquisition processing and the data output processing. The processor that executes at least processing other than the data acquisition processing and the data output processing may be the processor that executes the data acquisition processing and the data output processing, or may be a processor different from the processor that executes the data acquisition processing and the data output processing. The output data may be output, for example, to a terminal device or display device that displays the output data, or to a printing device that prints the output data. The terminal device may be, for example, a terminal device possessed by the rider, a terminal device possessed by an instructor who teaches the rider driving techniques, or a terminal device used to analyze driving techniques. The terminal device may be, for example, a mobile terminal, tablet terminal, or personal computer with a display unit.

In the present invention and its embodiments, a course may or may not be a course identified by an actual physical line, such as a line marked on the road surface. In the present invention and its embodiments, the multiple J-shaped regions of the same shape and size that a course has may or may not be regions identified by actual physical lines, such as a line marked on the road surface. In the present invention and its embodiments, a course may be a course in which at least one guide element is provided on the road surface to guide the direction of travel of the straddled vehicle.

In the present invention and embodiments, the J-shaped region may be composed of a straight line region and an arc region connected to the end of the straight line region. The J-shaped region is preferably a region in which an arc region is connected to the rear end of the straight line region in the direction of travel of the straddled vehicle. This allows output data that more strongly reflects driving technique. The J-shaped region may also be a region in which an arc region is connected to the front end of the straight line region in the direction of travel of the straddled vehicle.

The length of the linear region may be 45 m or less. The length of the linear region may be 40 m or less. The length of the linear region may be 35 m or less. The length of the linear region may be 30 m or less. The length of the linear region may be 25 m or less. The length of the linear region may be 20 m or less. The length of the linear region may be 15 m or less. The length of the linear region may be 10 m or less. The length of the linear region may be 5 m or less. The length of the linear region may be 2 m or less. The length of the linear region may be 1 m or less.

The central angle of the arc region may be less than 180°. The central angle of the arc region may be 90° or close to it. The central angle of the arc region may be greater than 180°. The central angle of the arc region may be 270° or close to it.

The arc of the inner periphery of the arc region may be 3 m or less.

In the present invention and its embodiments, traveling through a J-shaped area three to seven consecutive times while the first vehicle speed condition is imposed on the rider means that neither the first travel nor the second travel described below occurs. The first travel is travel through the J-shaped area in a state where the first vehicle speed condition is not imposed or a vehicle speed condition different from the first vehicle speed condition is imposed, which is set between the Kth travel through the J-shaped area while the first vehicle speed condition is imposed and the K+1th travel through the J-shaped area while the first vehicle speed condition is imposed. The second travel is travel through a J-shaped area that is set between the Kth travel through the J-shaped area while the first vehicle speed condition is imposed and the K+1th travel through the J-shaped area while the first vehicle speed condition is imposed, and which has a different shape or size from the J-shaped area. K is a natural number between 3 and 6. Furthermore, if the vehicle speed when traveling through the J-shaped area is affected by starting or stopping, this travel through the J-shaped area is not counted as one travel through the J-shaped area while the first vehicle speed condition is imposed. The term "vehicle speed when traveling through the J-shaped region is affected by starting" means that the change in vehicle speed when traveling through the J-shaped region includes acceleration after starting, which is clearly different from the change in vehicle speed in the J-shaped region when the first vehicle speed condition is imposed. The term "vehicle speed when traveling through the J-shaped region is affected by stopping" means that the change in vehicle speed when traveling through the J-shaped region includes deceleration before stopping, which is clearly different from the change in vehicle speed in the J-shaped region when the first vehicle speed condition is imposed.
In the present invention and its embodiments, when a straddled vehicle travels through a J-shaped region three to seven consecutive times in a first period from start to stop on a course having multiple J-shaped regions of the same shape and size under a first vehicle speed condition, at least one of the start and stop positions may be on or off the course. That is, the following cases are possible: both the start and stop positions are on the course; the start position is on the course but the stop position is not on the course; the start position is not on the course but the stop position is on the course; or both the start and stop positions are not on the course. In the present invention and its embodiments, the first period from start to stop of the straddled vehicle may be the entire period from start to stop of the straddled vehicle, or a portion of the period from start to stop of the straddled vehicle.

In the present invention and embodiments, the first vehicle speed-related travel data may be data related to the vehicle speed when the vehicle travels through the J-shaped area three to seven times consecutively while the first vehicle speed condition is imposed, without traveling through the J-shaped area eight or more times consecutively while the first vehicle speed condition is imposed. Conversely, the first vehicle speed-related travel data may be data related to the vehicle speed when the vehicle travels through the J-shaped area three to seven times consecutively while the first vehicle speed condition is imposed, when the vehicle travels through the J-shaped area eight or more times consecutively while the first vehicle speed condition is imposed.
In the present invention and embodiments, the first vehicle speed-related driving data may be data generated using a Global Navigation Satellite System (GNSS), or may be data generated using a sensor mounted on the straddled vehicle without using a GNSS.

In the present invention and embodiments, the first vehicle speed-related physical quantity comparison data based at least on the first vehicle speed-related driving data is data generated at least based on the first vehicle speed-related driving data. The first vehicle speed-related driving data is data related to the vehicle speed when the vehicle travels N consecutive times through a J-shaped region with the first vehicle speed condition imposed, where N is 3 to 7 times. The first vehicle speed-related physical quantity comparison data is data in a format that compares at least one type of vehicle speed-related physical quantity for each of M consecutive times of traveling through a J-shaped region with the first vehicle speed condition imposed, where M is 3 to 7 times. If N is 3, M is the same as N. If N is 4 or more, M may be the same as N or may be less than N. In other words, in the present invention and embodiments, the number of times the J-shaped region is continuously traveled with the first vehicle speed condition imposed in the above description of the first vehicle speed-related physical quantity comparison data may be the same as or less than the number of times the J-shaped region is continuously traveled with the first vehicle speed condition imposed in the above description of the first vehicle speed-related travel data.

In the present invention and the embodiments, the first vehicle-speed-related physical quantity comparison data in a format for comparing at least one type of vehicle-speed-related physical quantity means that the first vehicle-speed-related physical quantity comparison data is in a format for visually comparing at least one type of vehicle-speed-related physical quantity, that is, when output data including the first vehicle-speed-related physical quantity comparison data is displayed on a display device, for example, a user can visually compare the first vehicle-speed-related physical quantity comparison data.
In the present invention and the embodiments, the at least one vehicle speed-related physical quantity for each of three to seven consecutive times of traveling through a J-shaped region under the first vehicle speed condition refers to at least one vehicle speed-related physical quantity for each J-shaped region.

The first vehicle speed condition or the second vehicle speed condition may include increasing the vehicle speed as much as possible while suppressing changes in the acceleration in the vehicle's forward direction. In this case, the vehicle speed in the J-shaped region may be constant, but the vehicle speed may differ for each journey through the J-shaped region. The first vehicle speed condition or the second vehicle speed condition may include increasing the maximum vehicle speed as much as possible while increasing changes in the acceleration in the vehicle's forward direction.

In the present invention and embodiments, the first vehicle speed-related driving data and the second vehicle speed-related driving data may be integrated data with a continuous time series, or may be separate data. The period from when the straddled vehicle starts to when it stops may include driving corresponding to the first vehicle speed-related driving data and driving corresponding to the second vehicle speed-related driving data.

Note that the above definitions of the first vehicle speed-related traveling data and the first vehicle speed-related physical quantity comparison data also apply, with necessary adjustments, to the second vehicle speed-related traveling data and the second vehicle speed-related physical quantity comparison data.

In the present invention and embodiments, the straddled vehicle travel corresponding to the first attitude-related travel data may be the same as or a part of the straddled vehicle travel corresponding to the first vehicle speed-related travel data. In other words, the measurement time of the first attitude-related travel data may be the same as or a part of the measurement time of the first vehicle speed-related travel data.
In the present invention and embodiments, the first attitude-related driving data may be, for example, data generated using a camera installed near the course, or data generated using a sensor or camera mounted on the straddled vehicle.

In the present invention and embodiments, the straddled vehicle travel corresponding to the first trajectory-related travel data may be the same as or a part of the straddled vehicle travel corresponding to the first vehicle speed-related travel data. In other words, the measurement time of the first trajectory-related travel data may be the same as or a part of the measurement time of the first vehicle speed-related travel data.

The straddled vehicle driving data processing device and straddled vehicle driving data processing method of the present invention use data processing that differs from that of the straddled vehicle driving data processing device of Patent Document 1, thereby improving the design flexibility of hardware resources.

First Embodiment
A straddled vehicle driving data processing device 1 and a straddled vehicle driving data processing method according to a first embodiment of the present invention will now be described with reference to Figure 1. Figure 1 shows the configuration of the straddled vehicle driving data processing device 1 of this embodiment and the processing steps of the straddled vehicle driving data processing method of this embodiment. Figure 1 also shows a motorcycle as an example of a straddled vehicle 10. However, the straddled vehicle 10 of this embodiment is not limited to a motorcycle. Note that second to sixth embodiments, which will be described later, all have the configuration of the first embodiment.

As shown in FIG. 1, the straddled vehicle driving data processing device 1 has a processor 2 and a non-transitory recording medium 3. The processor 2 is configured to execute at least a data acquisition process S1 and a data output process S2. The processor 2 executes the data acquisition process S1 and the data output process S2 by loading a program pre-stored on the non-transitory recording medium 3. The straddled vehicle driving data processing method of this embodiment includes at least a data acquisition process S1 and a data output process S2. In the data acquisition process S1, driving data 30 including at least first vehicle speed-related driving data 31 is acquired. The first vehicle speed-related driving data 31 is data related to the vehicle speed when the straddled vehicle 10 travels through the J-shaped region 21 consecutively three to seven times during a first period from the start to the stop of the straddled vehicle 10 on a course 20 having multiple J-shaped regions 21 of the same shape and size, with a first vehicle speed condition, which is a vehicle speed constraint, imposed on the rider R. FIG. 1 shows five specific examples of the course 20, but the shape of the course 20 in the first embodiment is not limited to these. In FIG. 1, the J-shaped region 21 is hatched. In the data output process S2, output data 40 including at least first vehicle-speed-related physical quantity comparison data 41 based at least on the acquired first vehicle-speed-related driving data 31 is output. The first vehicle-speed-related physical quantity comparison data 41 is data in a format that compares at least one vehicle-speed-related physical quantity related to vehicle speed for each of three to seven consecutive runs of driving through the J-shaped region 21 under the first vehicle speed condition. The output data 40 may be output, for example, to a terminal device (not shown) having a display unit. The output data 40 output to the terminal device having a display unit is displayed on the display unit (not shown) as driving technique information F. FIG. 1 includes an example of the driving technique information F.

The straddled vehicle driving data processing device 1 and straddled vehicle driving data processing method of this embodiment perform data processing differently from the straddled vehicle driving data processing device of Patent Document 1, thereby improving the design freedom of hardware resources.

Furthermore, according to the straddled vehicle driving data processing device 1 and the straddled vehicle driving data processing method of this embodiment, even if the type (model) of the straddled vehicle 10 is different, it is possible to output output data 40 including first vehicle speed-related physical quantity comparison data 41 that strongly reflects the driving technique of the rider R, using the same course and the same first vehicle speed conditions.
Furthermore, according to the straddled vehicle driving data processing device 1 and the straddled vehicle driving data processing method of this embodiment, even if the level of the rider R's driving skill is different, it is possible to output output data 40 including first vehicle speed-related physical quantity comparison data 41 that strongly reflects the rider R's driving skill, using the same course and the same first vehicle speed conditions.

In the example of FIG. 1, the first vehicle speed-related physical quantity comparison data 41 is data in a format that compares at least one type of vehicle speed-related physical quantity for each of five consecutive times traveling through the J-shaped region 21 while the first vehicle speed condition is imposed, but the first vehicle speed-related physical quantity comparison data 41 in the first embodiment is not limited to this. In other words, the first vehicle speed-related physical quantity comparison data 41 may be data in a format that compares at least one type of vehicle speed-related physical quantity for each of three, four, six, or seven consecutive times traveling through the J-shaped region 21 while the first vehicle speed condition is imposed.

In the example of FIG. 1, the first vehicle speed-related physical quantity comparison data 41 is data in a format in which at least one type of vehicle speed-related physical quantity is arranged in chronological order for each of three to seven consecutive trips through the J-shaped region 21 under the first vehicle speed condition, but the format of the first vehicle speed-related physical quantity comparison data 41 in the first embodiment is not limited to this.

In the example of FIG. 1, the first vehicle speed-related physical quantity comparison data 41 is data in a format that compares one type of vehicle speed-related physical quantity for each of three to seven consecutive times of traveling through the J-shaped region 21 while the first vehicle speed condition is imposed, but the first vehicle speed-related physical quantity comparison data 41 in the first embodiment is not limited to this. In other words, the first vehicle speed-related physical quantity comparison data 41 may be data in a format that compares multiple types of vehicle speed-related physical quantities for each of three to seven consecutive times of traveling through the J-shaped region 21 while the first vehicle speed condition is imposed.

In the first vehicle speed-related physical quantity comparison data 41, at least one type of vehicle speed-related physical quantity for each of three to seven consecutive times of traveling through the J-shaped region 21 under the first vehicle speed condition may include, for example, a maximum vehicle speed for each J-shaped region 21, a minimum vehicle speed for each J-shaped region 21, a maximum positive acceleration of the straddled vehicle 10 in the forward direction for each J-shaped region 21, a minimum negative acceleration of the straddled vehicle 10 in the forward direction for each J-shaped region 21, a maximum acceleration of the straddled vehicle 10 in the left-right direction for each J-shaped region 21, a maximum acceleration of the straddled vehicle 10 in the left-right direction for each J-shaped region 21, a maximum value of the vehicle speed for each J-shaped region 21, a minimum value of the vehicle speed for each J-shaped region 21, a maximum ... The rotational acceleration may include at least one of the maximum value of the rotational acceleration around an axis along the vehicle vertical direction of the straddled vehicle 10 for each J-shaped region 21, the maximum value of the centrifugal force acting on the straddled vehicle 10 for each J-shaped region 21, the maximum value of the inertial force in the vehicle left-right direction acting on the straddled vehicle 10 for each J-shaped region 21, the maximum value of the lateral force acting on the wheels of the straddled vehicle 10 for each J-shaped region 21, and the maximum value of the inclination angle in the vehicle left-right direction of the body frame of the straddled vehicle 10 with respect to the vehicle vertical direction for each J-shaped region 21.
In the first vehicle speed-related physical quantity comparison data 41, at least one type of vehicle speed-related physical quantity for each of three to seven consecutive times of driving through the J-shaped region 21 under the first vehicle speed condition may include a type of vehicle speed-related physical quantity different from the above.

Second Embodiment
A straddled vehicle travel data processing device 1 and a straddled vehicle travel data processing method according to a second embodiment of the present invention will now be described with reference to FIG.

The J-shaped region 21 of the course 20 used in the second embodiment consists of a linear region 22 and an arc-shaped region 23 connected to the end of the linear region 22. The width of the J-shaped region 21 is 2 m. The length L of the linear region 22 is greater than 0 m and less than or equal to 65 m. The radius D of the arc of the inner peripheral edge of the arc region 23 is greater than or equal to 2 m and less than or equal to 10 m. The central angle θ of the arc region 23 is greater than or equal to 90° and less than or equal to 270°. Note that while Figure 2 is a diagram for explaining the J-shaped region 21 used in the second embodiment, the shape of the J-shaped region 21 in the second embodiment is not limited to the shape shown in Figure 2.

Third Embodiment
A straddled vehicle travel data processing device 1 and a straddled vehicle travel data processing method according to a third embodiment of the present invention will now be described with reference to Fig. 3. The third embodiment may have the same configuration as the second embodiment.

In the third embodiment, data acquisition processing S1 acquires driving data 30 including at least first vehicle-speed-related driving data 31 and second vehicle-speed-related driving data 32. The second vehicle-speed-related driving data 32 is data related to the vehicle speed when the straddled vehicle 10 travels through the J-shaped region 21 three to seven consecutive times during a second period from the start to the stop of the straddled vehicle 10 on a course 20 having multiple J-shaped regions 21 of the same shape and size, with a second vehicle speed condition imposed on the rider R that is a vehicle speed constraint different from the first vehicle speed condition. In the third embodiment, output data 40 output in data output processing S2 is data in which at least first vehicle-speed-related physical quantity comparison data 41 based at least on the acquired first vehicle-speed-related driving data 31 and second vehicle-speed-related physical quantity comparison data 42 based at least on the acquired second vehicle-speed-related driving data 32 are associated. The second vehicle speed-related physical quantity comparison data 42 is data comparing at least one vehicle speed-related physical quantity related to the vehicle speed for each of three to seven consecutive trips through the J-shaped region 21 under the second vehicle speed condition. Figure 3 includes an example of driving technique information F when the output data 40 of the third embodiment is displayed as driving technique information F on a terminal device (not shown) having a display unit.

The first vehicle speed condition and the second vehicle speed condition may include different constraints on the acceleration of the straddled vehicle 10 in the vehicle forward direction. For example, if the first vehicle speed condition includes suppressing changes in the acceleration of the straddled vehicle 10 in the vehicle forward direction, the second vehicle speed condition may include increasing changes in the acceleration of the straddled vehicle 10 in the vehicle forward direction. Also, for example, if the first vehicle speed condition includes increasing changes in the acceleration of the straddled vehicle 10 in the vehicle forward direction, the second vehicle speed condition may include suppressing changes in the acceleration of the straddled vehicle 10 in the vehicle forward direction. The first vehicle speed condition and the second vehicle speed condition may include constraints on the acceleration in the vehicle forward direction other than these. The first vehicle speed condition and the second vehicle speed condition do not have to include constraints on the acceleration in the vehicle forward direction.

Figure 4 shows an example of driving technique information F when the output data 40 of the fourth embodiment is displayed as driving technique information F on a terminal device (not shown) having a display unit. In the example of Figure 4, the multiple types of vehicle speed-related physical quantities include the maximum value of the inclination angle for each J-shaped region 21 as well as the minimum value of the vehicle speed for each J-shaped region 21. However, in the fourth embodiment, the multiple types of vehicle speed-related physical quantities may include vehicle speed-related physical quantities other than the maximum value of the inclination angle for each J-shaped region 21, as well as the minimum value of the vehicle speed for each J-shaped region 21. For example, the vehicle speed-related physical quantities other than the maximum tilt angle for each J-shaped region 21 included in the multiple types of vehicle speed-related physical quantities may include at least any of the maximum vehicle speed for each J-shaped region 21, the maximum positive acceleration of the straddled vehicle 10 in the forward direction for each J-shaped region 21, the minimum negative acceleration of the straddled vehicle 10 in the forward direction for each J-shaped region 21, the maximum acceleration of the straddled vehicle 10 in the left-right direction for each J-shaped region 21, the maximum rotational acceleration of the straddled vehicle 10 about an axis along the vertical direction of the vehicle for each J-shaped region 21, the maximum centrifugal force acting on the straddled vehicle 10 for each J-shaped region 21, the maximum inertial force acting on the straddled vehicle 10 in the left-right direction for each J-shaped region 21, and the maximum lateral force acting on the wheels of the straddled vehicle 10 for each J-shaped region 21.
