DETAILED DESCRIPTION OF THE INVENTION

[0010] In the information processing device according to the present disclosure, when first information is received, the control unit outputs second information including information indicating the scale of the first vehicle accident. The information processing device according to the present disclosure is a computer mounted on a connected vehicle (first vehicle) that communicates via V2X. The first information according to the present disclosure is information including location information of an accident involving a vehicle (first vehicle accident) and image data of the first vehicle accident. Such first information is transmitted from an on-board device of the accident vehicle, a connected vehicle in the vicinity of the accident vehicle, or a roadside device in the vicinity of the accident vehicle. The second information according to the present disclosure is information for calling attention to the first vehicle accident and includes information indicating the scale of the first vehicle accident. The second information is generated based on the first information. The second information is output, for example, through a display and / or a speaker mounted on the first vehicle.

[0011] According to the information processing device of the present disclosure, the second information can be output to notify the driver of the first vehicle of the scale of the first vehicle accident. This allows the driver of the first vehicle to recognize the scale of the first vehicle accident. As a result, for example, if the scale of the first vehicle accident is large, the driver of the first vehicle can pay more attention to the first vehicle accident than if the scale is small.

[0012] Specific embodiments of the present disclosure will be described below with reference to the accompanying drawings. Unless otherwise specified, the hardware configurations, module configurations, functional configurations, and the like described in the following embodiments are not intended to limit the technical scope of the disclosure to those configurations alone.

[0013] <Embodiment> In this embodiment, an example will be described in which an information processing device according to the present disclosure is applied to a system that provides driving assistance for connected vehicles using V2X.

[0014] (System Overview) 1 is a diagram showing an overview of a system according to this embodiment. The system according to this embodiment includes a first vehicle 10 and an in-vehicle device 100. The first vehicle 10 is a connected vehicle driven by a user who is the target of driving assistance. The in-vehicle device 100 is a computer mounted on the first vehicle 10, and is an example of an "information processing device" according to the present disclosure.

[0015] The in-vehicle device 100 receives first information using V2X. The first information is information about an accident (first vehicle accident) involving a vehicle other than the first vehicle 10. In this embodiment, the first information includes location information of the first vehicle accident, image data of the first vehicle accident, and the time of occurrence of the first vehicle accident. Such first information is broadcast from an in-vehicle device of a connected vehicle other than the first vehicle 10, a roadside device, or the like. Connected vehicles other than the first vehicle 10 include, for example, the accident vehicle and a connected vehicle that detected the first vehicle accident. The image data of the first vehicle accident is image data captured by the connected vehicle or roadside device that is the source of the first information. In addition, the time of occurrence of the first vehicle accident is not limited to the time when the first vehicle accident actually occurred, but may be the time when image data of the first vehicle accident was captured, or the time when the first vehicle accident was detected by a connected or roadside device, etc.

[0016] When receiving the first information, the in-vehicle device 100 issues a warning about the first vehicle accident. The first vehicle 10 is notified of prompting information (second information) to the user of the first vehicle 10. In this embodiment, the second information includes information indicating the scale of the first vehicle accident and information indicating the length of time that has elapsed since the occurrence of the first vehicle accident (hereinafter, sometimes referred to as the "first length of time"). This enables the user of the first vehicle 10 to pay attention according to the scale of the first vehicle accident and the first length of time. For example, the larger the scale of the first vehicle accident and the shorter the first length of time, the more the user of the first vehicle 10 can pay increased attention to the first vehicle accident.

[0017] (Hardware configuration of the first vehicle) Fig. 2 is a diagram showing an example of the hardware configuration of a first vehicle 10 in this embodiment. As shown in Fig. 2, the first vehicle 10 in this embodiment is configured to include an on-board device 100, an ECU 110, and a vehicle speed sensor 120. Note that, although the example shown in Fig. 2 extracts and illustrates only the hardware configuration related to driving assistance using V2X, the first vehicle 10 may include other hardware configurations. For example, in addition to the components shown in Fig. 2, the first vehicle 10 may include a prime mover, a transmission, a braking system, electrical components, a battery, an advanced safety system, and the like.

[0018] The in-vehicle device 100 receives the first information using V2X communication and notifies the user of the first vehicle 10 of the second information. As shown in FIG. 2 , the in-vehicle device 100 includes a processor 101, a main memory device 102, an auxiliary memory device 103, an output device 104, a position acquisition unit 105, a camera 106, a communication unit 107, and an in-vehicle communication unit 108.

[0019] The processor 101 is an arithmetic processing device such as a CPU (Central Processing Unit) or a DSP (Digital Signal Processor). The stored program is loaded into the main memory device 102 and executed, and the in-vehicle device 100 is controlled through this execution.

[0020] The main storage device 102 includes, for example, a RAM (Random Access Memory) and a ROM (Read Only Memory). The main memory 102 provides a storage area and a working area for loading programs stored in the auxiliary memory 103. The main memory 102 is also used as a buffer for the arithmetic processing by the processor 101.

[0021] The auxiliary storage device 103 is, for example, an EPROM (Erasable Programmable ROM) or The auxiliary storage device 103 is a removable medium, i.e., a hard disk drive (HDD). The auxiliary storage device 103 may include a removable storage medium. The removable medium is, for example, a disk storage medium such as a USB (Universal Serial Bus) memory, a CD (Compact Disc), or a DVD (Digital Versatile Disc). The auxiliary storage device 103 stores various programs and data used by the processor 101 when executing each program.

[0022] The programs stored in the auxiliary storage device 103 include an OS (Operating System) as well as dedicated programs for causing the processor 101 to execute processes related to driving assistance using V2X.

[0023] The output device 104 is a device that presents information to the user of the first vehicle 10. In this embodiment, the output device 104 includes a display, a speaker, and the like. The display may be a multi-information display (MID) or a display of a navigation system that is already installed in the first vehicle 10.

[0024] The position acquisition unit 105 is a device that acquires the current position of the first vehicle 10. The position acquisition unit 105 in the vehicle 10 acquires the current position of the first vehicle 10. The position acquisition unit 105 is, for example, a GPS (Global Positioning System) receiver. The location information acquired by the location acquisition unit 105 is, for example, geographic coordinates such as latitude and longitude.

[0025] The camera 106 captures images of the outside of the first vehicle 10. The camera 106 may be a dedicated camera, or may be a camera for a drive recorder or an advanced safety system.

[0026] The communication unit 107 is a device that performs V2X communication. The communication unit 107 in this embodiment performs V2X communication using short-range communication (e.g., communication within a range of several hundred meters to several kilometers). The communication unit 107 performs V2X communication using wireless communication based on a communication standard such as the Bluetooth (registered trademark) Low Energy standard (hereinafter referred to as BLE), NFC (Near Field Communication), UWB (Ultra Wideband), DSRC (Dedicated Short Range Communications), or Wi-Fi (registered trademark).

[0027] The in-vehicle communication unit 108 is an interface for communicating with the ECU 110 via an in-vehicle network. The in-vehicle network may be a CAN (Controller Area Network), a LIN (Loopback Path Network), or the like. (Local Interconnect Network), or a network based on standards such as FlexRay.

[0028] The ECU 110 is a computer that controls various devices (for example, a motor, a transmission, a braking system, electrical components, a battery, an advanced safety system, and the like) mounted on the first vehicle 10. The ECU 110 detects the traveling speed (first traveling speed) of the first vehicle 10 via the vehicle speed sensor 120, and controls various devices according to the first traveling speed. In this embodiment, the ECU 110 detects the first traveling speed in response to a request from the in-vehicle device 100, and transmits the detected first traveling speed to the in-vehicle device 100.

[0029] (Functional configuration of the in-vehicle device) The functional configuration of the in-vehicle device 100 in this embodiment will be described with reference to Fig. 3. As shown in Fig. 3, the in-vehicle device 100 has a control unit F110 as its functional components. Note that the functional components of the in-vehicle device 100 are not limited to the example shown in Fig. 3, and components may be omitted, replaced, or added as appropriate.

[0030] The control unit F110 is realized by the processor 101 of the in-vehicle device 100 loading a dedicated program stored in the auxiliary storage device 103 into the main storage device 102 and executing the program. The control unit F110 is implemented by an ASIC (Application Specific Integrated Circuit) Or it is realized by hardware circuits such as FPGA (Field Programmable Gate Array). That's fine.

[0031] The control unit F110 receives, via the communication unit 107, first information transmitted from other vehicles or roadside devices located within a V2X communication range (for example, within a radius of several hundred meters to several kilometers centered on the first vehicle 10). In this embodiment, the first information includes location information of the first vehicle accident, image data of the first vehicle accident, and the time of occurrence of the first vehicle accident. The location information of the first vehicle accident is, for example, information indicating the location of the first vehicle accident (the location of the point where the first vehicle accident occurred or the location of the accident vehicle related to the first vehicle accident), and is, for example, geographic coordinates such as latitude and longitude indicating the location.

[0032] The control unit F110 determines whether the location of the first vehicle accident is in the traveling direction of the first vehicle 10 based on the location information included in the first information and the current location of the first vehicle 10. If it is determined that the location of the vehicle accident is on the traveling direction side of the first vehicle 10, the control unit F110 notifies the second information. On the other hand, if it is determined that the location of the first vehicle accident is not on the traveling direction side of the first vehicle 10, the control unit F110 does not notify the second information. This is because the communication range of V2X is within a radius of several hundred meters to several kilometers centered on the first vehicle 10, and the in-vehicle device 100 may also receive the first information regarding a vehicle accident that occurred on the opposite side (rear side) of the traveling direction of the first vehicle 10.

[0033] Here, an example of a method for determining whether the location of the first vehicle accident is in the traveling direction of the first vehicle 10 will be described with reference to Figures 4 and 5. Figures 4 and 5 are diagrams showing an orthogonal coordinate system (hereinafter sometimes referred to as "first coordinate system") with the current position of the first vehicle 10 as its origin. The Y axis in Figures 4 and 5 represents the distance in the traveling direction of the first vehicle 10. The X axis in Figures 4 and 5 represents the distance in the horizontal direction (first direction) perpendicular to the traveling direction of the first vehicle 10.

[0034] When the communication unit 107 of the in-vehicle device 100 receives the first information, the control unit F110 acquires the current position (geographic coordinates) of the first vehicle 10 through the position acquisition unit 105. The control unit F110 converts a geographic coordinate system including the position information included in the first information and the current position of the first vehicle 10 into the first coordinate system shown in Figures 4 and 5. The control unit F110 identifies the Y coordinate of the position of the first vehicle accident in the first coordinate system ("Y1" in Figure 4 or "Y2" in Figure 5).

[0035] The control unit F110 determines whether the location of the first vehicle accident is in the traveling direction of the first vehicle 10 based on whether the Y coordinate (Y1 or Y2) of the location of the first vehicle accident in the first coordinate system is positive or negative. Here, if the first vehicle accident is located in the traveling direction of the first vehicle 10, the Y coordinate (Y1) of the location of the first vehicle accident in the first coordinate system will be a positive value, as shown in FIG. 4. On the other hand, if the first vehicle accident is located behind the first vehicle 10, the Y coordinate (Y2) of the location of the first vehicle accident in the first coordinate system will be a negative value, as shown in FIG. 5. Therefore, in this embodiment, the control unit F110 determines that the location of the first vehicle accident is in the traveling direction of the first vehicle 10 if the Y coordinate of the location of the first vehicle accident in the first coordinate system is a positive value. Furthermore, the control unit F110 determines that the position of the first vehicle accident is behind the first vehicle 10 if the Y coordinate of the position of the first vehicle accident in the first coordinate system is a negative value.

[0036] If it is determined that the location of the first vehicle accident is in the traveling direction of the first vehicle 10, the control unit F110 calculates a second time length. The second time length is a length of time that is predicted to be required for the first vehicle 10 to reach the location of the first vehicle accident. In calculating the second time length, the control unit F110 acquires a distance (first distance length) from the current location of the first vehicle 10 to the location of the first vehicle accident and a traveling speed (first traveling speed) of the first vehicle 10. The first distance length is acquired by calculating a relative distance in geographic coordinates between the current location of the first vehicle 10 and the location of the first vehicle accident. Note that the Y coordinate (Y1) of the location of the first vehicle accident in the first coordinate system illustrated in FIG. 5 may be used as the first distance length. The first traveling speed is acquired by the control unit F110 transmitting a signal requesting the first traveling speed to the ECU 110 via the in-vehicle communication unit 108. The control unit F110 calculates the second time length based on the first distance length and the first running speed.

[0037] The control unit F110 determines whether the second time length is equal to or less than a first threshold. The first threshold is, for example, a time length that is assumed to increase the likelihood that the user of the first vehicle 10 will be required to take action to avoid a collision with the accident vehicle, if the second time length is equal to or less than the first threshold. Such a first threshold may be set based on the results of an experiment, a simulation, or the like.

[0038] If it is determined that the second time length is equal to or less than the first threshold, the control unit F110 immediately generates second information and outputs the generated second information. If it is determined that the second time length is longer than the first threshold, the control unit F110 waits until the second time length becomes equal to or less than the first threshold before generating and outputting the second information. When generating the second information, the control unit F110 determines the scale of the first vehicle accident and calculates the first time length.

[0039] In this embodiment, the number of accident vehicles involved in the first vehicle accident is used as the scale of the first vehicle accident. In this case, the control unit F110 may determine the number of accident vehicles involved in the first vehicle accident, for example, by performing image recognition processing on image data included in the first information. Note that the scale of the first vehicle accident may also be determined by the area of ​​the road occupied by the accident vehicles involved in the first vehicle accident, or the like.

[0040] In this embodiment, the first time length is the length of time that has elapsed since the occurrence of the first vehicle accident to the present time. In this case, the control unit F110 calculates the first time length by, for example, subtracting the occurrence time of the first vehicle accident from the present time.

[0041] The control unit F110 generates second information based on the number of accident vehicles involved in the first vehicle accident and the first time length. The second information is information for calling attention to accident vehicles (accident vehicles involved in the first vehicle accident) located around the path of the first vehicle 10, and includes the number of accident vehicles and the first time length. The control unit F110 outputs the generated second information through the output device 104. In this case, the control unit F110 may display characters indicating the second information on the display of the output device 104, or may output audio indicating the second information from the speaker of the output device 104. Note that when characters indicating the second information are displayed on the display of the output device 104, a notification sound may be output from the speaker of the output device 104 to call the user's attention.

[0042] (Processing flow) Next, the flow of processing executed by the in-vehicle device 100 in this embodiment will be described with reference to Fig. 6. Fig. 6 is a flowchart showing a processing routine executed by the in-vehicle device 100 when the communication unit 107 of the in-vehicle device 100 receives the first information as a trigger. The processing routine of Fig. 6 is executed by the processor 101 of the in-vehicle device 100, but here the processing routine will be described assuming that the functional component (control unit F110) of the in-vehicle device 100 is the executing unit.

[0043] 6, when the communication unit 107 of the in-vehicle device 100 receives first information, the first information is passed from the communication unit 107 to the control unit F110. As a result, the control unit F110 receives the first information through the communication unit 107 (step S101). After completing the process of step S101, the control unit F110 executes the process of step S102.

[0044] In step S102, the control unit F110 calculates the Y coordinate of the position of the first vehicle accident in the first coordinate system. In detail, the control unit F110 acquires the current position of the first vehicle 10 through the position acquisition unit 105. The control unit F110 converts the geographic coordinate system including the position information included in the first information and the current position of the first vehicle 10 into the first coordinate system exemplified in FIGS. 4 and 5 described above. The control unit F110 calculates the Y coordinate (Y1 or Y2) of the position of the first vehicle accident in the first coordinate system. After completing the processing of step S102, the control unit F110 executes the processing of step S103.

[0045] In step S103, the control unit F110 determines whether the Y coordinate calculated in step S102 is equal to or greater than "0." If the Y coordinate calculated in step S102 is less than "0," If the Y coordinate calculated in step S102 is equal to or greater than "0" (positive determination in step S103), the location of the first vehicle accident is located on the opposite side of the traveling direction of the first vehicle 10 (rear side of the first vehicle 10). In this case, the control unit F110 ends the execution of this processing routine. As a result, the second information is not notified for the first vehicle accident. On the other hand, if the Y coordinate calculated in step S102 is equal to or greater than "0" (positive determination in step S103), the location of the first vehicle accident is located on the traveling direction side of the first vehicle 10. In this case, the control unit F110 executes the processing from step S104 onwards.

[0046] In step S104, the control unit F110 acquires the traveling speed of the first vehicle 10 by transmitting a signal requesting the traveling speed of the first vehicle 10 to the ECU 110 via the in-vehicle communication unit 108. After completing execution of step S104, the control unit F110 executes the process of step S105.

[0047] In step S105, the control unit F110 calculates a time length (second time length) that is predicted to be required for the first vehicle 10 to reach the location of the first vehicle accident. Specifically, the control unit F110 calculates a distance length (first distance length) from the current location of the first vehicle 10 to the location of the first vehicle accident based on the location information of the first information included in the first information and the current location of the first vehicle 10. The control unit F110 acquires a detection signal (traveling speed of the first vehicle 10) from the vehicle speed sensor 120 by communicating with the ECU 110 via the in-vehicle communication unit 108. The control unit F110 calculates the second time length based on the first distance length and the traveling speed of the first vehicle 10. After completing the process of step S105, the control unit F110 executes the process of step S106.

[0048] In step S106, the control unit F110 determines whether the second time length calculated in step S105 is equal to or less than the first threshold. If the second time length is longer than the first threshold (negative determination in step S106), the control unit F110 executes the processes of steps S105 and S106 again. If the second time length is equal to or less than the first threshold (positive determination in step S106), the control unit F110 executes the process of step S107.

[0049] In step S107, the control unit F110 executes image recognition processing on the image data included in the first information to determine the number of accident vehicles involved in the first vehicle accident. After completing the processing of step S107, the control unit F110 executes the processing of step S108.

[0050] In step S108, the control unit F110 calculates the length of time that has elapsed since the first vehicle accident occurred to the present time (first time length) based on the occurrence time of the first vehicle accident included in the first information and the current time. After completing the processing of step S108, the control unit F110 executes the processing of step S109.

[0051] In step S109, the control unit F110 generates second information based on the number of accident vehicles determined in step S107 and the first time length calculated in step S108. The second information includes information for urging the user to pay attention to accident vehicles (accident vehicles related to the first vehicle accident) located around the path of the first vehicle 10, the number of accident vehicles, and the first time length. After completing the process of step S109, the control unit F110 executes the process of step S110.

[0052] In step S110, the control unit F110 outputs the second information generated in step S109 through the output device 104. As a result, the user of the first vehicle 10 is notified that the accident vehicle is located around the path of the first vehicle 10, as well as the scale of the first vehicle accident and the length of time that has elapsed since the first vehicle accident occurred. When the process is completed, the process routine ends.

[0053] (Actions and Effects of the Embodiments) In the embodiment described above, when the in-vehicle device 100 receives the first information, it notifies the user of the first vehicle 10 of the second information including information regarding the scale of the first vehicle accident and the first time length. This allows the user of the first vehicle 10 to pay even more attention to the first vehicle accident when the scale of the first vehicle accident is large compared to when the scale is small. Furthermore, the user of the first vehicle 10 can pay even more attention to the first vehicle accident when the first time length is short compared to when the first time length is long. Therefore, according to the present embodiment, it is possible to urge the user of the first vehicle 10 to pay attention according to the scale and first time length of the first vehicle accident.

[0054] Furthermore, in the above-described embodiment, the second information is notified to the user of the first vehicle 10 at a timing when the second time length is equal to or less than the first threshold. Here, if the second information is notified at a timing when the second time length is relatively long, the user's attention may decrease before the first vehicle 10 reaches the vicinity of the first vehicle accident. In contrast, if the second information is notified at a timing when the first time length is equal to or less than the first threshold, it is possible to prevent the user's attention from decreasing before the first vehicle 10 reaches the vicinity of the first vehicle accident.

[0055] Therefore, according to this embodiment, it is possible to give the user of the first vehicle 10 an appropriate warning.

[0056] <Modification> If a traffic jam has occurred due to the first vehicle accident when the in-vehicle device 100 receives the first information, the control unit F110 may notify the user of the first vehicle 10 of the third information in addition to the second information. The third information is information indicating that a traffic jam has occurred due to the first vehicle accident.

[0057] Here, the control unit F110 of the in-vehicle device 100 may determine whether a traffic jam caused by the first vehicle accident has occurred. In this case, the control unit F110 may determine whether a traffic jam caused by the first vehicle accident has occurred, for example, based on the number of other vehicles present between the position of the first vehicle accident and the first vehicle 10 and the traveling speeds of those other vehicles. The number and traveling speeds of other vehicles present between the position of the first vehicle accident and the first vehicle 10 may be determined by performing image recognition processing on image data captured by the camera 106 of the first vehicle 10. Alternatively, the in-vehicle device 100 may determine the number and traveling speeds of surrounding vehicles by communicating with the surrounding vehicles via the communication unit 107. The control unit F110 may determine that a traffic jam caused by the first vehicle accident has occurred if the number of other vehicles present between the position of the first vehicle accident and the first vehicle 10 is equal to or greater than a predetermined number and the average (or maximum) traveling speeds of those other vehicles are equal to or less than a predetermined traveling speed.

[0058] Furthermore, the control unit F110 of the in-vehicle device 100 may acquire the traveling speeds of other vehicles that have passed the location of the first vehicle accident by communicating with the other vehicles via the communication unit 107. If the acquired traveling speed is faster than the traveling speed of other vehicles that exist between the location of the first vehicle accident and the first vehicle 10, the control unit F110 may notify the user of the first vehicle 10 of information indicating that the congestion will be resolved once the first vehicle 10 passes the location of the first vehicle accident.

[0059] <Other> The above-described embodiment and modifications are merely examples, and the present disclosure should not be construed as departing from the gist thereof. For example, the above-described embodiments and modifications can be freely combined as long as no technical contradiction occurs.

[0060] Furthermore, a process described as being performed by one device may be shared and executed by multiple devices. Alternatively, a process described as being performed by different devices may be executed by a single device. In a computer system, the hardware configuration for realizing each function can be flexibly changed. [Explanation of symbols]
