A driving diagnosis system according to an embodiment of the present invention will be described. The driving diagnosis system is a system that determines whether the driving conditions of a vehicle are favorable for road warning information. Road warning information is information including road regulations and dangers that is provided separately from road traffic information provided by a traffic system such as VICS (Vehicle Information and Communication System) (registered trademark). The road traffic information provided by the traffic system does not necessarily cover information including current road regulations and dangers, and may be insufficient. Therefore, information including current road regulations and dangers is obtained as road warning information from a vehicle that is capable of communication. This makes it possible to provide the driver with current road warning information that could not be covered by the general road traffic information provided by the traffic system. In addition, a driving diagnosis can be performed to determine whether the driving conditions are favorable for road warning information based on the current situation.

In the driving diagnosis system of this embodiment, it is determined whether the driving conditions of the vehicle are favorable for the road warning information. Whether the driving conditions of the vehicle are favorable for the road warning information is determined based on whether the vehicle complies with traffic regulations. The criteria for whether the vehicle complies with traffic regulations may be, for example, driving conditions such as whether the vehicle speed is not zero on a road where parking and stopping is prohibited, or whether the shift lever is not in P (parking). Note that situations that are unfavorable for the road warning information include not only cases where traffic regulations are not complied with, but also cases where the vehicle is approaching an area where crackdowns are frequent. Approaching an area where crackdowns are frequent is determined from the vehicle's position information. An area where crackdowns are frequent is, for example, an area where traffic violations occur frequently.

(Overall composition)
As shown in Fig. 1, a driving diagnosis system 10 according to an embodiment of the present invention includes a plurality of vehicles 12, a center server 30 as a driving diagnosis device, and a terminal 40. Each vehicle 12 is equipped with an on-board device 20. The on-board device 20, the center server 30, and the terminal 40 are connected to each other via a network N. Although Fig. 1 illustrates three center servers 30, the vehicles 12, the on-board devices 20, and one terminal 40, the number of vehicles 12, the on-board devices 20, and the terminal 40 is not limited to this. The terminal 40 or the on-board device 20 is an example of one or more providers of the present invention.

The center server 30 is installed, for example, at the manufacturer that produces the vehicle 12 or at a car dealership affiliated with the manufacturer. Examples of the terminal 40 include a smartphone or a personal computer owned by the administrator of the monitoring system for the vehicle 12 or the owner of the vehicle 12.

The terminal 40 is equipped with a GUI (Graphical User Interface), and is capable of adding location information to road warning information on the GUI and selecting the information. The terminal 40 outputs a selection operation of a point on a map to the center server 30. The selection operation is an operation for adding location information to road warning information. If the terminal 40 is a personal computer, the selection operation can be performed by clicking a mouse, and if the terminal 40 is a type that is operated with fingers such as a smartphone, the selection operation can be performed by pinching or tapping. The vehicle-mounted device 20 also has a GUI function similar to that of the terminal 40. As a result, the vehicle-mounted device 20 is configured to be able to add location information to road warning information using a similar GUI. When obtaining road warning information from the vehicle-mounted device 20, not only information selected by an operation on the GUI but also an image of the surroundings of the vehicle 12 may be included as information indicating danger that is a risk factor. By storing and analyzing such captured images in the center server 30, it is possible to extract high-risk areas, such as areas where dangerous driving is common or areas where there are frequent crackdowns.

An example of the GUI will be described. FIG. 2 is a diagram showing an example of a selection operation of a point on a map displayed on the GUI. As shown in FIG. 2, the GUI 60A can display a map 60B of any coordinate. The GUI 60A can select a point by forming a selection range 60C at any point on the map 60B. The terminal 40 or the vehicle-mounted device 20 transmits the selection operation to the center server 30. The center server 30 adds position information to the road warning information in the selection range 60C of the point selected by the selection operation. The GUI 60A also allows the setting operation of the road warning information from the setting interface 60D. The setting interface 60D in FIG. 2 shows examples of items that can be set regarding the road warning information, such as a setting name, a vehicle speed condition, and a shift condition. The setting interface 60D may be input when road warning information is first received for the point. The setting name indicates the type of road warning information. The item of the setting name can be set by inputting an arbitrary name or by selecting from preset setting names. In the case of creating road warning information of parking and stopping prohibition, the user who operates the GUI 60A on the terminal 40 or the vehicle-mounted device 20 creates a selection range 60C of the section of the parking and stopping prohibition by a selection operation, and sets the setting name, the vehicle speed condition and the shift condition related to the parking and stopping prohibition by a setting operation. Note that the GUI 60A is an example, and any GUI may be used as long as it is configured to add position information to the road warning information by selecting a point on the map. Also, forming the selection range 60C and performing a selection operation is an example, and any operation method may be used as long as the operation allows a point on the map 60B to be selected. In this way, the center server 30 accepts a selection operation of adding position information to the road warning information from the terminal 40 or the vehicle-mounted device 20. Also, the center server 30 accepts a setting operation of the road warning information to be newly added to the point on the map 60B. In addition, the terminals 40 or in-vehicle devices 20 that can set road warning information using the setting interface 60D may be restricted to terminals 40 operated by an administrator or some of the in-vehicle devices 20. In the restricted terminals 40 or in-vehicle devices 20, the pre-set road warning information may be selected from the setting name item on the GUI 60A, and only the location selection operation may be performed.

The CPU 20A is a central processing unit that executes various programs and controls each part. That is, the CPU 20A reads the programs from the ROM 20B and executes the programs using the RAM 20C as a working area.

The ROM 20B stores various programs and data. In this embodiment, the ROM 20B stores a control program 50 that collects vehicle information related to the state and control of the vehicle 12 from the ECU 22 and permits or restricts the use of functions or the application of equipment of the vehicle 12. The ROM 20B also stores history information, which is backup data for the vehicle information.
The RAM 20C temporarily stores programs or data as a working area.

The in-vehicle communication I/F 20D is an interface for connecting to each ECU 22. This interface uses a communication standard based on the CAN protocol. The in-vehicle communication I/F 20D is connected to the external bus 20H.

The wireless communication I/F 20E is a wireless communication module for communicating with the center server 30. The wireless communication module uses communication standards such as 5G, LTE, and Wi-Fi (registered trademark). The wireless communication I/F 20E is connected to the network N.

The ECU 22 includes at least an ADAS (Advanced Driver Assistance System)-ECU 22A, a steering ECU 22B, a brake ECU 22C, and an engine ECU 22D.

The ADAS-ECU 22A controls the advanced driving assistance system. The ADAS-ECU 22A is connected to a vehicle speed sensor 24A, a yaw rate sensor 24B, and an external sensor 24C that constitute the in-vehicle equipment 24. The external sensor 24C is a group of sensors used to detect the surrounding environment of the vehicle 12. The external sensor 24C includes, for example, a camera that captures images of the surroundings of the vehicle 12, a millimeter wave radar that transmits detection waves and receives reflected waves, and a lidar (Laser Imaging Detection and Ranging) that scans the area ahead of the vehicle 12.

The steering ECU 22B controls the power steering. A steering angle sensor 24D that constitutes the in-vehicle equipment 24 is connected to the steering ECU 22B. The steering angle sensor 24D is a sensor that detects the steering angle of the steering wheel.

The brake ECU 22C controls the brake system of the vehicle 12. The brake actuator 24E, which constitutes the in-vehicle equipment 24, is connected to the brake ECU 22C.

The engine ECU 22D controls the engine of the vehicle 12. The engine ECU 22D is connected to a throttle actuator 24F and sensors 24G that constitute the in-vehicle equipment 24. The sensors 24G include an oil temperature sensor for measuring the temperature of the engine oil, an oil pressure sensor for measuring the oil pressure of the engine oil, and a rotation sensor for detecting the engine speed.

The information system ECU 22E controls the car navigation system, audio, etc. A GPS device 29 constituting the in-vehicle equipment 24 is connected to the information system ECU 22E. The GPS device 29 is a device that measures the current position of the vehicle 12. The GPS device 29 includes an antenna (not shown) that receives signals from GPS satellites. The GPS device 29 may be directly connected to the in-vehicle device 20.

The information system ECU 22E has a function to display road warning information with added position information output from the center server 30, and a function to report warning information when the driving conditions are unfavorable for the road warning information. The information system ECU 22E also has a function to enable selection and setting operations using a GUI 60A similar to that of the terminal 40, and transmits road warning information to the center server 30. The function to display road warning information, for example, displays points corresponding to the road warning information on a map of the car navigation system by pinning them down. This allows the driver to visually grasp points where restrictions and dangers exist. The function to report warning information, for example, displays warning marks by the car navigation system and provides voice guidance by audio. Note that these functions may be performed by other devices within the vehicle-mounted device 20 or external devices.

Figure 4 shows an example of the display of road warning information with added location information. The information system ECU 22E in the vehicle-mounted device 20 displays a map 61B corresponding to the location where the vehicle 12 is traveling on a GUI 61A as shown in Figure 4. In the GUI 61A, roads in a range 61C corresponding to the location information of the road warning information are pinned on the map 61B and displayed together with the setting name 61D of the road warning information. In the example of Figure 4, the setting name 61D of the road warning information displayed is "No parking". This type of display allows the driver of the vehicle 12 to check the road warning information updated by the center server 30.

(Center server)
5, the center server 30 includes a CPU 30A, a ROM 30B, a RAM 30C, a storage 30D, and a communication I/F 30E. The CPU 30A, the ROM 30B, the RAM 30C, the storage 30D, and the communication I/F 30E are connected to each other via an internal bus 30G so as to be able to communicate with each other. The functions of the CPU 30A, the ROM 30B, the RAM 30C, and the communication I/F 30E are the same as those of the CPU 20A, the ROM 20B, the RAM 20C, and the wireless communication I/F 20E of the vehicle-mounted device 20 described above. The communication I/F 30E may perform wired communication.

The storage 30D as a memory is configured with a HDD (Hard Disk Drive) or SSD (Solid State Drive) and stores various programs and various data. In this embodiment, the storage 30D stores a processing program 100, a vehicle information DB (database) 110, a traffic information DB 120, a road warning information DB 130, and a judgment information DB 140. The ROM 30B may store the processing program 100, the vehicle information DB 110, the traffic information DB 120, the road warning information DB 130, and the judgment information DB 140.

The processing program 100, which serves as a driving diagnosis program, is a program for controlling the center server 30. With the execution of the processing program 100, the center server 30 executes a driving diagnosis process that determines whether the vehicle's driving conditions are favorable for the road warning information.

The vehicle information DB 110 stores vehicle information acquired from the vehicle 12 and position information corresponding to the vehicle information. The vehicle information includes information related to driving operations and traveling, such as vehicle speed, acceleration, yaw rate, steering angle, accelerator opening, brake pedal force or stroke, etc. The position information of the vehicle 12 is updated as an image of the outside of the vehicle 12 captured by a camera serving as the external sensor 24C and the current position of the vehicle 12 obtained from the GPS device 29.
Furthermore, the vehicle information DB 110 stores the determination result for each vehicle 12 by the determination unit 206 .
The traffic information DB 120 stores map data for acquiring the position on a map where the vehicle 12 is traveling. The traffic information DB 120 also stores road traffic information corresponding to the map data.
The road warning information DB 130 stores road warning information to which position information received from the terminal 40 or the vehicle-mounted device 20 has been added.

The judgment information DB 140 stores criteria for determining whether the driving situation is favorable for the road warning information. The criteria may be received from the setting interface 60D on the GUI 60A of the terminal 40, or a predetermined setting may be stored. The criteria are set for each type of road warning information. The types of road warning information include those related to compliance with traffic regulations such as parking and stopping prohibitions and speed limits, and those related to areas where crackdowns are frequent. Therefore, the criteria include criteria related to compliance with traffic regulations and criteria related to areas where crackdowns are frequent. Criteria related to compliance with traffic regulations include criteria related to parking and stopping prohibitions and criteria related to speed limits. Criteria related to parking and stopping prohibitions include criteria such as whether the vehicle speed is not zero on a road where parking and stopping prohibitions are set, and whether the shift lever is not in park. Criteria related to areas where crackdowns are frequent include criteria such as whether the position information of the vehicle 12 is approaching an area where crackdowns are frequent by more than a certain distance. These criteria settings can be edited, changed, added, deleted, etc., as appropriate from the settings interface 60D.

As shown in FIG. 6, in the center server 30 of this embodiment, the CPU 30A executes the processing program 100 to function as a setting unit 200, an output unit 202, an acquisition unit 204, and a determination unit 206.

The setting unit 200 accepts a selection operation from the terminal 40, and stores the location information corresponding to the selection operation as road warning information in the road warning information DB 130.

When the road warning information DB 130 is updated, the output unit 202 outputs the road warning information with the location information added to the vehicle-mounted device 20 of the vehicle 12. Furthermore, when the judgment unit 206 judges that the situation is not favorable for the road warning information, the output unit 202 outputs warning information to the vehicle-mounted device 20. The warning information may have warning contents determined according to the type of road warning information. If the type of road warning information is related to traffic regulations, the warning contents are a warning that the traffic regulations are being violated. If the type of road warning information is related to an area where crackdowns are frequent, the warning contents are a warning to be careful of approaching that area.

The acquisition unit 204 acquires vehicle information and location information corresponding to the vehicle information from the vehicle-mounted device 20, and stores the information in the vehicle information DB 110. The acquisition unit 204 also acquires road warning information from the terminal 40 or the vehicle-mounted device 20, which is the source of the information.

The determination unit 206 determines whether the driving conditions of the vehicle 12 are favorable for the road warning information based on the vehicle information and position information in the vehicle information DB 110, the road warning information in the road warning information DB 130, and the criteria in the determination information DB 140.

(Flow of Control)
A process flow as a control method executed in the driving diagnosis system 10 of the present embodiment will be described with reference to the sequence of Fig. 7 and the flowchart of Fig. 8. The process in the center server 30 is executed by the CPU 30A functioning as each part of the center server 30.

In step S10 of FIG. 7, the terminal 40 accepts a selection operation of a location for road warning information from the GUI 60A. In step S11, the terminal 40 outputs the selection operation to the center server 30. Note that a setting operation may be accepted together with the selection operation. Furthermore, the processing of steps S10 and S11 may be performed by the vehicle-mounted device 20.

In step S12, the CPU 30A of the center server 30 adds location information to the road warning information at the point selected by the received selection operation, and updates the road warning information DB 130.

In step S13, the CPU 30A of the center server 30 outputs the road warning information with the location information of the road warning information DB 130 added to the vehicle-mounted devices 20 mounted on the multiple vehicles 12. This allows the updated road warning information to be shared among the multiple vehicles 12.

In step S14, the CPU 20A of the vehicle-mounted device 20 displays the road warning information on the map 61B of the GUI 61A at a location corresponding to the location information added to the road warning information.

In step S15, the CPU 20A in the vehicle-mounted devices 20 of the multiple vehicles 12 outputs the collected vehicle information and the location information corresponding to the vehicle information to the center server 30. The center server 30 acquires the vehicle information and the location information corresponding to the vehicle information, and stores them in the vehicle information DB 110.

In step S16, the CPU 30A of the center server 30 performs a determination process to determine whether the driving conditions of the vehicle 12 are favorable for the road warning information. The details of the determination process will be described later.

In step S17, if the determination process in step S16 determines that the driving conditions of the vehicle 12 are not favorable for the road warning information, the CPU 30A in the center server 30 outputs warning information to the vehicle-mounted device 20. Note that the target to which the warning information is output here is the vehicle-mounted device 20 of the specific vehicle 12 that is the target of the determination process.

In step S18, the CPU 20A of the vehicle-mounted device 20 issues a warning based on the warning information.

Next, the details of the determination process in step S16 will be described. Note that the determination process is periodically executed for each of the plurality of vehicles 12 at regular intervals, regardless of the sequence flow shown in FIG.
In step S100 of FIG. 8, the CPU 30A acquires vehicle information and position information for the vehicle-mounted device 20 of the target vehicle 12 from the vehicle information DB 110, and acquires road warning information from the road warning information DB .

In step S101, the CPU 30A compares the acquired position information of the vehicle 12 with the acquired road warning information, and determines whether the position information of the vehicle 12 indicates that the vehicle 12 is located at a location corresponding to the road warning information. If it is determined that the vehicle 12 is located at a location corresponding to the road warning information, the process proceeds to step S102. If it is determined that the vehicle 12 is not located at a location corresponding to the road warning information, the determination process ends.

In step S102, CPU 30A obtains criteria corresponding to the road warning information obtained in step S100 from judgment information DB 140.

In step S103, the CPU 30A compares the acquired vehicle information with the acquired criteria to determine whether the driving conditions of the vehicle 12 are favorable for the road warning information. If it is determined that the driving conditions of the vehicle 12 are favorable for the road warning information, the process proceeds to step S104. If it is determined that the driving conditions of the vehicle 12 are not favorable for the road warning information, the process proceeds to step S105.

The judgment will be described using an example in which the type of road warning information is a parking and stopping prohibition. In the case of a parking and stopping prohibition, the criteria are (A1) that the vehicle speed of the vehicle 12 is not zero, and (A2) that the shift lever is not in park. For example, the vehicle speed is obtained from the vehicle speed sensor 24A and then transmitted to the center server 30 as vehicle information, and the position of the shift lever is obtained from the engine ECU 22D and then transmitted to the center server 30 as vehicle information.

Then, in the process of step S103, it is determined whether the vehicle speed included in the vehicle information meets the criterion (A1) and whether the state of the shift lever included in the vehicle information meets the criterion (A2). In this process, if both the criteria (A1) and (A2) are met, it is determined that the driving conditions of the vehicle 12 are favorable with respect to the road warning information. In this process, if either the criteria (A1) or (A2) are not met, it is determined that the driving conditions of the vehicle 12 are unfavorable with respect to the road warning information.

In step S104, the CPU 30A stores the determination that the driving conditions of the vehicle 12 are good in the vehicle information DB 110.

In step S105, the CPU 30A stores the determination result that the driving conditions of the vehicle 12 are not good in the vehicle information DB 110.

In step S106, the CPU 30A outputs warning information to the vehicle-mounted device 20. Note that step S106 corresponds to step S17 in the sequence of FIG. 7 above.

The center server 30 accumulates the results of the judgment that the condition is not good, as in steps S104 and S105 above. Here, the center server 30 may use the accumulated judgment results to treat locations where the judgment result of being not good reaches a certain level or more as locations where incidents frequently occur. When the vehicle 12 approaches a location where incidents frequently occur, the center server 30 outputs warning information to the vehicle-mounted device 20 in advance. Based on the warning information, the vehicle-mounted device 20 issues a warning via the information system ECU 22E or the like. This makes it possible to inform the driver that more caution is required, and to prevent further incidents from occurring at the location where incidents frequently occur.

In addition, the determination results of steps S104 and S105 may include recording a log of vehicle information for vehicle 12. By accumulating logs in this manner, it is possible to understand the driving conditions of vehicles 12 that meet the criteria for road warning information and those that do not.

(summary)
The center server 30 as a driving diagnosis device of this embodiment adds location information to road warning information including road restrictions and dangers at a point selected by a selection operation received from the terminal 40 or the vehicle-mounted device 20. The center server 30 outputs the road warning information with the location information added to the vehicle-mounted devices 20 mounted on the multiple vehicles 12. The center server 30 acquires vehicle information and location information corresponding to the vehicle information, and performs a determination process to determine whether the driving conditions of the vehicle 12 are favorable for the road warning information. In this way, information on current road restrictions and dangers can be provided to the driver. In addition, a driving diagnosis service function for current road restrictions and dangers can be provided to the driver of the vehicle.

In the above embodiment, the various processes executed by CPU 20A and CPU 30A by reading software (programs) may be executed by various processors other than the CPU. Examples of processors in this case include PLDs (Programmable Logic Devices) such as FPGAs (Field-Programmable Gate Arrays) whose circuit configuration can be changed after manufacture, and dedicated electrical circuits such as ASICs (Application Specific Integrated Circuits) that are processors with circuit configurations designed specifically to execute specific processes. The above-mentioned processes may be executed by one of these various processors, or by a combination of two or more processors of the same or different types (e.g., multiple FPGAs, a combination of a CPU and an FPGA, etc.). The hardware structure of these various processors is, more specifically, an electrical circuit that combines circuit elements such as semiconductor elements.

In the above embodiment, each program has been described as being pre-stored (installed) in a non-transitory computer-readable recording medium. For example, the program in the vehicle-mounted device 20 is pre-stored in ROM 20B, and the processing program 100 in the center server 30 is pre-stored in storage 30D. However, this is not limiting, and each program may be provided in a form recorded on a non-transitory recording medium such as a CD-ROM (Compact Disc Read Only Memory), a DVD-ROM (Digital Versatile Disc Read Only Memory), or a USB (Universal Serial Bus) memory. The program may also be downloaded from an external device via a network.

The process flow described in the above embodiment is an example, and unnecessary steps may be deleted, new steps may be added, or the process order may be rearranged, without departing from the spirit of the invention.
