Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Specific dimensions, materials, numerical values, etc. shown in these embodiments are merely examples to facilitate understanding of the invention and do not limit the present invention unless otherwise specified. Furthermore, in this specification and drawings, elements having substantially the same function and configuration are designated by the same reference numerals to avoid redundant explanation, and elements not directly related to the present invention are not shown.

<Vehicle configuration>
The configuration of a vehicle 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG.

Figure 1 is a schematic diagram showing the general configuration of a vehicle 1. As shown in Figure 1, the vehicle 1 includes an engine 11, a transmission 12, a differential device 13, drive wheels 14, a shift change device 15, a shift position sensor 16, an operation load sensor 17, a load change device 18, and a control device 19.

The engine 11 generates power using fuel such as gasoline. The engine 11 outputs power to drive the drive wheels 14. The output shaft of the engine 11 is connected to the transmission 12. The power output from the engine 11 is transmitted to the transmission 12.

The transmission 12 has multiple gear stages. The output shaft of the transmission 12 is connected to the differential device 13. The power transmitted to the transmission 12 has its rotation speed changed by the transmission 12 at a gear ratio corresponding to each gear stage, and is then transmitted to the differential device 13.

The power transmitted to the differential device 13 is distributed by the differential device 13 to a pair of left and right drive wheels 14. The drive wheels 14 may be either the front wheels or the rear wheels. The power output from the engine 11 may also be transmitted to both the front and rear wheels. In this case, the output shaft of the transmission 12 is connected to a front differential device that distributes power to the pair of left and right front wheels, and a rear differential device that distributes power to the pair of left and right rear wheels.

The shift change device 15 is a device for changing the gear positions of the transmission 12. The shift change device 15 is provided with a shift lever 15a. The shift lever 15a accepts a shift operation by the driver, which is an operation for changing the gear positions of the transmission 12. The shift lever 15a corresponds to an example of an operating unit according to the present invention.

The shift lever 15a moves in response to a shift operation by the driver. By changing the shift position, which is the position of the shift lever 15a, the gear of the transmission 12 is changed to the gear corresponding to the shift position. The operation of moving the shift lever 15a to change the shift position corresponds to a shift operation.

Figure 2 is a schematic diagram showing an example of the shift positions of the shift change device 15. In the example shown in Figure 2, the shift positions include a first range P1, a second range P2, a third range P3, a fourth range P4, a fifth range P5, and a reverse range PR. The transmission 12 has first, second, third, fourth, fifth, and reverse gears as gear positions.

The first range P1, second range P2, third range P3, fourth range P4, fifth range P5 and reverse range PR correspond to first gear, second gear, third gear, fourth gear, fifth gear and reverse gear, respectively. When the gear is first gear, second gear, third gear, fourth gear or fifth gear, power is transmitted to the drive wheels 14 in a direction that moves the vehicle 1 forward. The gear ratio decreases in the order of first gear, second gear, third gear, fourth gear and fifth gear. When the gear is reverse gear, power is transmitted to the drive wheels 14 in a direction that moves the vehicle 1 backward.

The shift position sensor 16 detects the shift position and outputs the detection result to the control device 19. The shift position sensor 16 is provided in the shift change device 15.

The operation load sensor 17 detects the operation load applied to the shift lever 15a by the driver during a shift operation and outputs the detection result to the control device 19. The operation load sensor 17 is provided in the shift change device 15.

The load changing device 18 changes the operating load applied to the shift lever 15a by the driver during a shift operation. For example, the load changing device 18 is a device that applies a load to the shift lever 15a. Such a device may be, for example, an electric actuator such as a motor, or a hydraulic actuator.

For example, the load changing device 18 applies a load to the shift lever 15a in the same direction as the movement of the shift lever 15a during a shift operation. In this case, the direction of the load applied to the shift lever 15a by the load changing device 18 is the same as the direction of the operating load applied by the driver. This makes the shift operation easier, resulting in a smaller operating load applied by the driver. Also, for example, the load changing device 18 applies a load to the shift lever 15a in the opposite direction to the movement of the shift lever 15a during a shift operation. In this case, the direction of the load applied to the shift lever 15a by the load changing device 18 is opposite the direction of the operating load applied by the driver. This makes the shift operation heavier, resulting in a larger operating load applied by the driver.

In the above, an example was described in which the load change device 18 is a device that applies a load to the shift lever 15a. However, the load change device 18 may be any device that changes the operating load, and may be a device other than a device that applies a load to the shift lever 15a. For example, if a damping force is applied to the shift lever 15a by hydraulic oil, the load change device 18 may be a device that changes the operating load by changing the temperature of the hydraulic oil to change the damping force.

The control device 19 has one or more processors 19a and one or more memories 19b connected to the processors 19a. The processors 19a include, for example, a CPU (Central Processing Unit). The memories 19b include, for example, a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM is a memory element that stores programs and calculation parameters used by the CPU. The RAM is a memory element that temporarily stores data such as variables and parameters used in processing executed by the CPU.

The control device 19 communicates with each device provided in the vehicle 1 (e.g., the transmission 12, the shift position sensor 16, the operation load sensor 17, and the load change device 18). Communication between the control device 19 and each device is achieved, for example, using CAN (Controller Area Network) communication.

Figure 3 is a block diagram showing an example of the functional configuration of the control device 19. For example, as shown in Figure 3, the control device 19 has an acquisition unit 191, a control unit 192, a memory unit 193, and a learning unit 194. Note that various processes, including those described below, performed by the acquisition unit 191, the control unit 192, and the learning unit 194 may be executed by the processor 19a. In detail, various processes are performed by the processor 19a executing programs stored in the memory 19b. The functions of the memory unit 193 are realized by the memory 19b.

The acquisition unit 191 acquires various information and outputs it to the control unit 192 and the memory unit 193. For example, the acquisition unit 191 acquires information from the shift position sensor 16 and the operation load sensor 17.

The control unit 192 controls the operation of each device within the vehicle 1. For example, the control unit 192 can change the gear position of the transmission 12 by controlling the operation of the transmission 12. Specifically, the control unit 192 changes the gear position of the transmission 12 to the gear position corresponding to the shift position detected by the shift position sensor 16. The gear position of the transmission 12 can be changed, for example, in response to a control command output from the control device 19. However, the method for changing the gear position of the transmission 12 may be a shift-by-wire method as described above, or a mechanical method other than a shift-by-wire method. Furthermore, for example, the control unit 192 can adjust the operating load of the driver when shifting gears by controlling the operation of the load change device 18.

The memory unit 193 stores various types of information. For example, the memory unit 193 stores information acquired by the acquisition unit 191. The information stored in the memory unit 193 is used in the processing performed by the control unit 192 and the learning unit 194. The memory unit 193 also stores the learning results of the learning unit 194, which will be described later.

The learning unit 194 learns the shift operation characteristics, which are the characteristics of the shift operation performed by the driver. In this embodiment, the control unit 192 controls the operation of the load changing device 18 based on the results of learning of the shift operation characteristics by the learning unit 194. This improves driver comfort. Details of the shift operation characteristics will be described later.

<Vehicle operation>
Next, the operation of the vehicle 1 according to the embodiment of the present invention will be described with reference to FIGS.

As described above, in this embodiment, the learning unit 194 learns the shift operation characteristics, which are the characteristics of the shift operation performed by the driver. Hereinafter, the process related to learning the shift operation characteristics performed by the learning unit 194 will also be referred to as the learning process. Also, as described above, in this embodiment, the control unit 192 controls the operation of the load changing device 18 based on the results of learning of the shift operation characteristics by the learning unit 194. Hereinafter, the process related to controlling the load changing device 18 performed by the control unit 192 will also be referred to as the load adjustment process.

Below, the learning process performed by the learning unit 194 and the load adjustment process performed by the control unit 192 will be explained in that order.

Figure 4 is a flowchart showing an example of the flow of the learning process performed by the learning unit 194 of the control device 19. The control flow of the learning process shown in Figure 4 is repeatedly executed, for example, in parallel with the control flow of the load adjustment process shown in Figure 8 (described below), or sequentially.

When the control flow shown in FIG. 4 starts, first, in step S101, the learning unit 194 learns the shift operation characteristics based on the shift operation information. The shift operation information is information related to the shift operation by the driver. The shift operation information is acquired by the acquisition unit 191 while the vehicle 1 is traveling, and is stored and accumulated in the memory unit 193. Examples of shift operation information will be described later. The shift operation characteristics are the characteristics of the transition of the operating load during the shift operation, and are unique to the driver.

Figure 5 shows an example of the transition of operating load. In Figure 5, the vertical axis represents operating load [N], and the horizontal axis represents time [s]. In the example of Figure 5, a shift operation begins at time T0. That is, at time T0, the driver begins applying load to the shift lever 15a and begins moving the shift lever 15a. The operating load then increases from time T0 to time T1 and reaches its maximum at time T1. The operating load at time T1 corresponds to the maximum operating load, which is the value of the operating load when the operating load reaches its maximum during the shift operation. After that, the operating load decreases from time T1 onwards, and the shift operation ends at time T2. That is, at time T2, the driver stops applying load to the shift lever 15a, and the movement of the shift lever 15a ends. As a result, the shift position changes to the shift position desired by the driver, and the gear of the transmission 12 is changed.

In step S101, the learning unit 194 learns the shift operation characteristics using, for example, the maximum operating force and the maximum load arrival time as shift operation information. The maximum load arrival time is the time from the start of the shift operation to the time when the operating force reaches its maximum during the shift operation. In the example of FIG. 5, the maximum load arrival time is the time from time T0 to time T1. Note that in step S101, for example, the average values of the maximum operating force and the average values of the maximum load arrival time obtained during a predetermined number of previous shift operations are used as the shift operation information. The maximum operating force and the maximum load arrival time for each shift operation can be generated based on the detection results of the operating force sensor 17 stored in the memory unit 193.

Figure 6 shows an example of the relationship between shift operation characteristics, maximum operating load, and maximum load arrival time. In Figure 6, the vertical axis represents maximum operating load [N], and the horizontal axis represents maximum load arrival time [s].

In the example of FIG. 6, if the maximum operating load is less than the reference load and the time to reach maximum load is shorter than the reference time, the learning unit 194 determines shift operation characteristic C1 as the driver's shift operation characteristic. Furthermore, if the maximum operating load is greater than the reference load and the time to reach maximum load is shorter than the reference time, the learning unit 194 determines shift operation characteristic C2 as the driver's shift operation characteristic. Furthermore, if the maximum operating load is less than the reference load and the time to reach maximum load is longer than the reference time, the learning unit 194 determines shift operation characteristic C3 as the driver's shift operation characteristic. Furthermore, if the maximum operating load is greater than the reference load and the time to reach maximum load is longer than the reference time, the learning unit 194 determines shift operation characteristic C4 as the driver's shift operation characteristic. Thus, in the example of FIG. 6, in learning the shift operation characteristic, one of four pre-prepared candidate shift operation characteristics C1, C2, C3, and C4 is obtained as the learning result.

Here, each of the shift operation characteristics C1, C2, C3, and C4 is associated with a transition model of the operation load. The transition model of the operation load models the transition of the operation load. Figure 7 shows an example of the transition model of the operation load corresponding to each of the shift operation characteristics C1, C2, C3, and C4. In Figure 5, the vertical axis represents the operation load [N], and the horizontal axis represents time [s].

Figure 7 shows point D1, where the operation load reaches its maximum in the transition model corresponding to shift operation characteristic C1; point D2, where the operation load reaches its maximum in the transition model corresponding to shift operation characteristic C2; point D3, where the operation load reaches its maximum in the transition model corresponding to shift operation characteristic C3; and point D4, where the operation load reaches its maximum in the transition model corresponding to shift operation characteristic C4. Comparing points D1 and D2 with points D3 and D4, it can be seen that the shift operation characteristics C1 and C2 have a shorter time to reach their maximum load than the shift operation characteristics C3 and C4. Furthermore, comparing points D1 and D3 with points D2 and D4, it can be seen that the maximum operation load is smaller in the shift operation characteristics C1 and C3 than in the shift operation characteristics C2 and C4.

Shift operation characteristics C1, for example, correspond to the shift operation characteristics of a driver who prioritizes safety. Shift operation characteristics C2, for example, correspond to the shift operation characteristics of a driver who prioritizes the feeling of switching to the desired shift position. Shift operation characteristics C3, for example, correspond to the shift operation characteristics of a driver who prioritizes ride comfort. Shift operation characteristics C4, for example, correspond to the shift operation characteristics of a driver who prioritizes smooth shifting.

In the load adjustment process described below, the operation of the load change device 18 is controlled so that the operation load transitions in accordance with a transition model corresponding to the shift operation characteristics learned by the learning unit 194. This allows the driver to perform shift operations with an operation feel that suits their preferences.

In the above, an example was described in which the learning unit 194 determines the driver's shift operation characteristics from four pre-prepared candidate shift operation characteristics. However, the number of candidate shift operation characteristics may be other than four.

In the above example, the learning unit 194 learns shift operation characteristics based on two types of shift operation information: maximum operating force and maximum load arrival time. However, the learning unit 194 may also learn shift operation characteristics based on one or more types of shift operation information. The learning unit 194 may also learn shift operation characteristics based on shift operation information other than maximum operating force and maximum load arrival time. For example, the learning unit 194 may learn shift operation characteristics using the total operation time as shift operation information. The total operation time is the time from the start of the shift operation to the end of the shift operation. In the example of FIG. 5, the total operation time is the time from time T0 to time T2. In this case, for example, the average value of the total operation time obtained for a predetermined number of previous shift operations is used as the shift operation information. The total operation time for each shift operation may be generated based on the detection results of the operating force sensor 17 stored in the memory unit 193.

Following step S101 in FIG. 4, in step S102, the learning unit 194 determines whether the shift operation characteristics obtained through learning differ from the registered shift operation characteristics. Here, the shift operation characteristics obtained through the previous learning are stored and registered in the memory unit 193.

If it is determined that the shift operation characteristics obtained through learning differ from the registered shift operation characteristics (YES in step S102), the process proceeds to step S103, where the learning unit 194 updates the registered shift operation characteristics to the shift operation characteristics obtained through this current learning. For example, if shift operation characteristic C2 was registered as the previous learning result and shift operation characteristic C1 is obtained as the current learning result, the learning unit 194 updates the registered shift operation characteristics to shift operation characteristic C1.

On the other hand, if it is determined that the shift operation characteristics obtained through learning are the same as the registered shift operation characteristics (NO in step S102), the process proceeds to step S104, and the learning unit 194 maintains the registered shift operation characteristics.

After step S103 or step S104, the control flow shown in Figure 4 ends.

Figure 8 is a flowchart showing an example of the flow of the load adjustment process performed by the control unit 192 of the control device 19. The control flow of the load adjustment process shown in Figure 8 is executed, for example, in parallel with the control flow of the learning process shown in Figure 4 or repeatedly in succession, as described above.

When the control flow shown in FIG. 8 starts, first, in step S201, the control unit 192 determines whether a shift operation by the driver has started. The control unit 192 can determine whether a shift operation has started, for example, based on the detection result of the operation load sensor 17.

If it is determined that a shift operation has not been initiated (NO in step S201), the control flow shown in FIG. 8 ends. On the other hand, if it is determined that a shift operation has been initiated (YES in step S201), the flow proceeds to step S202.

If step S201 returns YES, then in step S202, the control unit 192 drives the load changing device 18 based on the registered shift operation characteristics. Here, the control unit 192 controls the operation of the load changing device 18 so that the operation load transitions in accordance with a transition model corresponding to the registered shift operation characteristics.

For example, if the operational load detected by the operational load sensor 17 is large compared to the operational load at the same time on the transition model, the control unit 192 will cause the load change device 18 to apply a load to the shift lever 15a in the same direction as the movement of the shift lever 15a. This will make the shift operation lighter, and as a result, the operational load will be closer to the transition model. Also, for example, if the operational load detected by the operational load sensor 17 is small compared to the operational load at the same time on the transition model, the control unit 192 will cause the load change device 18 to apply a load to the shift lever 15a in the opposite direction to the movement of the shift lever 15a. This will make the shift operation heavier, and as a result, the operational load will be closer to the transition model.

Following step S202, in step S203, the control unit 192 determines whether the driver's shift operation has ended. The control unit 192 can determine whether the shift operation has ended, for example, based on the detection result of the operation load sensor 17.

If it is determined that the shift operation has not ended (NO in step S203), the process returns to step S202. On the other hand, if it is determined that the shift operation has ended (YES in step S203), the process proceeds to step S204.

If the determination in step S203 is YES, in step S204, the control unit 192 stops the load changing device 18, and the control flow shown in Figure 8 ends.

The above describes examples of processing performed by the control device 19 with reference to Figures 4 to 8. However, the control device 19 may perform other processing instead of the processing described above, or may perform additional processing other than the processing described above.

For example, the example has been described in which the learning unit 194 determines the driver's shift operation characteristics from among pre-prepared candidate shift operation characteristics during the learning process. However, the learning unit 194 may also generate the driver's shift operation characteristics based on shift operation information during the learning process. Furthermore, the learned shift operation characteristics do not necessarily need to be associated with a transition model of operation load. For example, the control unit 192 may learn the average value of the maximum operation load obtained in a predetermined number of past shift operations as the shift operation characteristics, and control the operation of the load changing device 18 so that the maximum operation load during the shift operation matches the learned average value.

Furthermore, for example, the learning unit 194 may learn shift operation characteristics separately for each driving location or driving situation. In this case, the shift operation characteristics obtained through learning are stored and registered in the memory unit 193 for each driving location or driving situation. For example, the learning unit 194 may learn shift operation characteristics separately for driving locations in urban areas, expressways, mountain passes, and snowy roads. For example, when learning shift operation characteristics for driving locations in urban areas, the learning unit 194 learns the shift operation characteristics based on shift operation information acquired while driving in urban areas. In this way, by learning shift operation characteristics separately for each driving location or driving situation, the driver can shift gears with an operation feel that suits their preferences depending on the driving location or driving situation.

Furthermore, for example, the learning results by the learning unit 194 may be stored in a cloud-based device that can wirelessly communicate with the vehicle 1. As a result, even when the driver switches to another vehicle and drives it, the control unit 192 can control the operation of the load changing device 18 based on the learning results of the shift operation characteristics by the learning unit 194.

<Vehicle Effects>
Next, the effects of the vehicle 1 according to the embodiment of the present invention will be described.

In the vehicle 1 according to this embodiment, the learning unit 194 of the control device 19 learns the shift operation characteristics, which are the characteristics of the driver's shift operation, based on shift operation information relating to the driver's shift operation. The control unit 192 of the control device 19 then controls the operation of the load changing device 18 based on the results of learning of the shift operation characteristics by the learning unit 194. Therefore, after appropriately learning the driver's unique shift operation characteristics, the shift operation characteristics can be reflected in the operation load during the shift operation. This allows the driver to perform shift operations with an operation feel that suits their preferences.

Furthermore, in the vehicle 1 according to this embodiment, it is preferable that the shift operation information includes a maximum operation load, which is the value of the operation load when the operation load is at its maximum during the shift operation. This makes it possible to appropriately learn the shift operation characteristics that indicate the driver's preference for maximum operation load. Therefore, the driver's preference for maximum operation load can be reflected in the operation load during the shift operation.

Furthermore, in the vehicle 1 according to this embodiment, the shift operation information preferably includes the maximum load arrival time, which is the time from the start of the shift operation to the time when the operation load reaches its maximum during the shift operation. This makes it possible to appropriately learn the shift operation characteristics that indicate the driver's preference for the maximum load arrival time. Therefore, the driver's preference for the maximum load arrival time can be reflected in the operation load during the shift operation.

Furthermore, in the vehicle 1 according to this embodiment, it is preferable that the shift operation information include the total operation time, which is the time from the start of the shift operation to the end of the shift operation. This makes it possible to appropriately learn the shift operation characteristics that indicate the driver's preference for total operation time. Therefore, the driver's preference for total operation time can be reflected in the operation load during the shift operation.

Furthermore, in the vehicle 1 according to this embodiment, the shift operation characteristics are associated with a transition model of the operation load, and the control unit 192 preferably controls the operation of the load changing device 18 so that the operation load transitions in accordance with the transition model corresponding to the learned shift operation characteristics. This makes it possible to appropriately adjust the transition of the operation load during the shift operation to suit the driver's preferences. Therefore, it is possible to appropriately enable the driver to perform the shift operation with an operation feel that suits their preferences.

The above describes a preferred embodiment of the present invention with reference to the accompanying drawings. However, it goes without saying that the present invention is not limited to the above-described embodiment, and that various modifications and alterations within the scope of the claims also fall within the technical scope of the present invention.

For example, the processes described using flowcharts in this specification do not necessarily have to be performed in the order shown in the flowcharts. Furthermore, additional processing steps may be employed, or some processing steps may be omitted.

For example, the above description was given of an example in which vehicle 1 is a manual vehicle. However, vehicle 1 may also be an automatic vehicle with a manual mode in which the gear position is changed in response to a shift operation. In this case, the learning process and load adjustment process described above can be performed in the manual mode.
