  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of an information system according to an embodiment of the present invention. The information system shown in FIG. 1 provides information on an automatic driving plan of the vehicle 100 to a user who is on the vehicle 100, and includes an in-vehicle device 1 and a communication terminal 2 mounted on the vehicle 100. The communication line network 3 and the server 4 are configured. The in-vehicle device 1 and the communication terminal 2 are connected by wired or wireless connection.

  The in-vehicle device 1 includes an ambient environment detection device 5 that is a device that detects the ambient environment of the vehicle 100, an HMI device 6 that provides an interface between the in-vehicle device 1 and a user, and various processes and controls related to traveling of the vehicle 100. The vehicle control device 7 that performs the above is connected via an in-vehicle communication network 8 provided in the vehicle 100. The in-vehicle communication network 8 is, for example, a CAN (Controller Area Network). The vehicle control device 7 acquires the detection result of the surrounding environment by the surrounding environment detection device 5 and the map data included in the in-vehicle device 1 via the in-vehicle communication network 8, and performs traveling control of the vehicle 100 using these. Thus, part or all of the driving operation performed by the user can be substituted and the vehicle 100 can be driven automatically. That is, the vehicle 100 capable of automatic driving is realized by the in-vehicle device 1, the surrounding environment detection device 5, and the vehicle control device 7.

  The ambient environment detection device 5 is installed in, for example, the front, rear, left and right sides of the vehicle 100 to photograph the surroundings of the vehicle 100, and transmits radio waves, infrared rays, sound waves, and the like around the vehicle 100. This is realized by radar, LiDAR (Light Detection and Ranging), sonar, or the like that detects the surrounding environment of the vehicle 100 by receiving the reflected wave. Hereinafter, LiDAR using light such as infrared rays and sonar using sound waves will be described as a kind of radar. The vehicle control device 7 is, for example, an ECU (Electronic Control Unit), and various types of devices are mounted on the vehicle 100 according to the function and the control target.

  The vehicle control device 7 acquires ambient environment information from the ambient environment detection device 5 via the in-vehicle communication network 8 and also acquires map information near the current position of the vehicle 100 from the in-vehicle device 1. The ambient environment information is information representing the ambient environment of the vehicle 100 detected by the ambient environment detection device 5, and the content thereof varies depending on the type of the ambient environment detection device 5. When there is an obstacle around the vehicle 100, the vehicle control device 7 can acquire information on the position, size, movement, etc. of the obstacle from the surrounding environment detection device 5 as the surrounding environment information. On the other hand, the map information near the current position of the vehicle 100 acquired from the in-vehicle device 1 includes information indicating the shape, width, number of lanes, and the like of the road on which the vehicle 100 is traveling. The vehicle control device 7 performs the automatic operation of the vehicle 100 by controlling the traveling state of the vehicle 100 based on these pieces of information. Note that the map information used for automatic driving by the vehicle control device 7 may be acquired from a device other than the in-vehicle device 1. Moreover, you may drive the vehicle 100 automatically using the map information which the vehicle control apparatus 7 itself has, without acquiring map information from another apparatus.

  However, when the detection accuracy of the surrounding environment of the vehicle 100 by the surrounding environment detection device 5 is insufficient, or when the accuracy of the map information is insufficient, the vehicle control device 7 has a high risk of automatic driving. And switch to manual operation. When the vehicle control device 7 requests switching from automatic driving to manual driving, the HMI device 6 issues a warning to the user and requests the user to stop the automatic driving of the vehicle 100 and switch to manual driving. When the user performs a predetermined switching operation using the HMI device 6 in response to this request, the vehicle control device 7 stops the automatic driving, and the vehicle 100 travels by the user's manual driving. Even in this case, driving assistance to the user may be performed by using the surrounding environment information acquired from the surrounding environment detection device 5, for example, notifying the user of an obstacle existing around the vehicle 100.

The communication terminal 2 is a mobile phone, for example. The communication network 3 is constructed by, for example, a mobile phone network or the Internet.

  The server 4 stores automatic driving histories of many vehicles including the vehicle 100. The in-vehicle device 1 transmits a travel history representing a history of a road on which the vehicle 100 traveled in an automatic operation or a manual operation to the server 4. The server 4 can record the automatic driving history of the vehicle 100 based on this by receiving the traveling history transmitted from the in-vehicle device 1.

  Although FIG. 1 shows an example in which one in-vehicle device 1 mounted on one vehicle 100 is connected to the server 4, the in-vehicle devices mounted on a large number of vehicles are actually the server 4.

Here, the types of the automatic driving elements represented by the automatic driving element information 23 are, for example, the types and operating states of the surrounding environment detection device 5 connected to the in-vehicle device 1 and used for the automatic driving of the vehicle 100, the types of the map DB 21, and the like. It is. Note that a part or all of the program executed by the CPU in the control unit 10 may be stored in the storage unit 20.

  The current position detection unit 30 detects the current position of the vehicle 100, that is, the current position of the user on the vehicle 100, and outputs the detection result to the control unit 10. The current position detection unit 30 is configured using, for example, a GPS sensor. When a GPS sensor is used as the current position detection unit 30, the control unit 10 may calculate the current position based on the GPS signal. Hereinafter, the current position (the current position of the user) of the vehicle 100 detected by the current position detection unit 30 is simply referred to as “current position”.

  In the HMI device 6, the display unit 61 displays various images and videos according to the control of the display control unit 14 included in the in-vehicle device 1. The display unit 61 is configured using, for example, a liquid crystal display. The operation input unit 62 receives an operation input from the user and outputs operation information corresponding to the operation content to the in-vehicle device 1. The operation input unit 62 includes, for example, a touch panel integrated with the display unit 61 and various switches.

  The control unit 110 of the server 4 includes a CPU, a ROM, a RAM, and the like (not shown), and performs various processes and operations for operating the server 4. The control unit 110 includes functional blocks of a communication control unit 111, a travel history collection unit 112, an operation condition information collection unit 113, an automatic driving history recording unit 114, and an automatic driving ratio determination unit 115 as functions thereof. The control unit 110 can realize these functional blocks by, for example, developing a program stored in the ROM into the RAM and executing it by the CPU. Details of these functional blocks included in the control unit 110 will be described later.

  The storage unit 120 is a nonvolatile storage medium, and is configured using, for example, an HDD (Hard Disk Drive), an SSD (Solid State Drive), a memory card, or the like. The storage unit 120 includes an automatic driving history DB 121 in which automatic driving histories of a large number of vehicles including the vehicle 100 connected to the server 4 are converted into a database, and an operation in which operating condition information relating to the operating conditions of automatic driving in each vehicle is converted into a database. And a condition information DB 122. Note that a part or all of the program executed by the CPU in the control unit 110 may be stored in the storage unit 120.

  Next, each functional block of the control part 10 of the vehicle-mounted apparatus 1 and the control part 110 of the server 4 is demonstrated.

  The communication control unit 11 controls the communication terminal 2 when the in-vehicle device 1 communicates with the server 4 via the communication terminal 2 and the communication line network 3. The in-vehicle device 1 can transmit and receive information to and from the server 4 by controlling the communication terminal 2 using the communication control unit 11.

  The automatic driving element information acquisition unit 12 acquires the automatic driving element information 23 from the surrounding environment detection device 5 or the map DB 21 and stores it in the storage unit 20. Specifically, as described above, information indicating the type and operation state is acquired from the surrounding environment detection device 5, and the type of map information used in the automatic driving performed by the vehicle control device 7 from the map DB 21. Get information indicating These pieces of information are combined and stored in the storage unit 20 as automatic driving element information 23.

  The current position acquisition unit 13 acquires the detection result of the current position from the current position detection unit 30, and refers to the map DB 21 to identify a link corresponding to the road on which the vehicle 100 is traveling. Then, for example, when the link changes due to the vehicle 100 passing through an intersection, the travel history recording unit 18 is notified to that effect.

  The display control unit 14 performs control to display a map screen on the display unit 61 of the HMI device 6 using the map DB 21 stored in the storage unit 20. On this map screen, a travel route from the current position to the destination where the vehicle 100 is scheduled to travel is shown, and an automatic driving plan of the vehicle 100 with respect to the travel route is displayed. In addition, the specific example of the automatic driving | operation plan displayed on the display part 61 by the display control part 14 is demonstrated later. In addition, when a camera is mounted as the ambient environment detection device 5, the display control unit 14 displays an image indicating the ambient environment of the vehicle 100 generated based on a captured image acquired from the camera, and the like. It can also be displayed and provided to the user.

  The in-vehicle communication interface unit 15 performs interface processing when the in-vehicle device 1 transmits / receives information to / from other devices via the in-vehicle communication network 8. The in-vehicle communication interface unit 15 may be realized using a hardware configuration different from the control unit 10. For example, when the in-vehicle communication network 8 is a CAN, the CAN controller can be used as the in-vehicle communication interface unit 15.

  The operation condition specifying unit 16 specifies an operation condition of automatic driving when the vehicle 100 travels on each road by automatic driving or manual driving. The automatic driving operation condition is a condition that affects the operation of the automatic driving in the vehicle 100, that is, a condition that affects the detection accuracy of the surrounding environment of the vehicle 100 by the surrounding environment detection device 5. Time zone, weather, road surface conditions, etc. The operation condition specifying unit 16 can specify the operation condition for automatic driving based on, for example, a photographed image of a camera included in the surrounding environment detection device 5 or the operation status of the wiper of the vehicle 100. As long as it affects the operation of automatic driving in the vehicle 100, other conditions may be specified as the operating conditions for automatic driving. The operating conditions for automatic driving specified by the operating condition specifying unit 16 are recorded in the travel history DB 22 in association with the travel history of the vehicle 100 for each road.

  The route setting unit 17 sets the destination of the vehicle 100 using the map DB 21 based on the destination information input by the user via the operation input unit 62 of the HMI device 6. Note that destination setting information may be acquired from a device other than the HMI device 6. Then, the route from the current position acquired by the current position acquisition unit 13 to the set destination is calculated, and the obtained route is set as the travel route of the vehicle 100. Note that the destination may be estimated or the route to the destination may be calculated based on the travel history of the vehicle 100 or the like. Further, the route calculation may be performed by a device other than the in-vehicle device 1, for example, the server 4.

  The travel history recording unit 18 records the travel history of the vehicle 100 in the travel history DB 22 on a link basis based on the travel link of the vehicle 100 specified by the current position acquisition unit 13. In the travel history DB 22, information indicating whether the vehicle 100 has traveled in automatic driving or manual driving is recorded for each link as the travel history of the vehicle 100. The travel history of the vehicle 100 recorded in the travel history DB 22 is transmitted from the in-vehicle device 1 to the server 4 at a predetermined timing by the communication control unit 11 and collected by the travel history collection unit 112 of the server 4. The details of the travel history DB 22 will be described later with reference to FIG.

  The communication control unit 111 performs communication control necessary when the server 4 communicates with the in-vehicle device 1 via the communication terminal 2 and the communication line network 3. The communication control unit 111 performs, for example, interface processing between the server 4 and the communication network 3 in communication control.

  The travel history collection unit 112 collects the travel history of the vehicle 100 transmitted from the in-vehicle device 1 at a predetermined timing and received by the communication control unit 111. The travel history collection unit 112 collects the travel history of each vehicle in the same manner from the in-vehicle devices mounted in a large number of vehicles connected to the server 4 in addition to the in-vehicle device 1 mounted in the vehicle 100. . The travel history of each vehicle including the vehicle 100 collected by the travel history collection unit 112 is temporarily stored in the storage unit 120 and used for processing performed by the automatic driving history recording unit 114.

  The operating condition information collection unit 113 collects operating condition information regarding the operating conditions of automatic driving when each vehicle including the vehicle 100 travels on the road, and accumulates it in the operating condition information DB 122. The operating condition information collection unit 113 is connected to, for example, an external server (not shown), and collects information such as weather and road surface conditions from each external server as operating condition information. Note that other information may be collected as the operation condition information as long as it relates to the operation conditions of the automatic driving, that is, it affects the operation of the automatic driving in each vehicle.

  The automatic driving history recording unit 114 records the automatic driving history for each road of the vehicle connected to the server 4 in the automatic driving history DB 121 based on the traveling history of each vehicle collected by the traveling history collecting unit 112. At this time, the automatic driving history recording unit 114 uses the types of automatic driving elements used for automatic driving in each vehicle and the operating conditions of automatic driving when each vehicle travels on the road in automatic driving or manual driving. Classify the running history of each vehicle. And the ratio of the vehicle which drive | worked by the automatic driving | running | working from the driving | running history of the vehicle for every classification | category is calculated | required per link, and the result is recorded on automatic driving | operation log | history DB121. The travel history classification method and the details of the automatic driving history DB 121 will be described later with reference to FIG.

  The automatic driving ratio determination unit 115 determines an automatic driving ratio corresponding to the vehicle 100 for each road link using the automatic driving history DB 121 in response to a request from the in-vehicle device 1. At this time, the automatic driving ratio determination unit 115 specifies the type of the automatic driving element used for the automatic driving in the vehicle 100 based on the automatic driving element information 23 transmitted from the in-vehicle device 1 and received by the communication control unit 111. The automatic driving history corresponding to this is acquired from the automatic driving history DB 121. And the automatic driving | running | working ratio corresponding to the vehicle 100 is calculated per link using the acquired automatic driving | operation log | history. Information representing the automatic driving ratio for each road link determined by the automatic driving ratio determining unit 115 is transmitted from the server 4 to the in-vehicle device 1 by the communication control unit 111 as automatic driving ratio information, and the vehicle 100 performed by the display control unit 14. It is used in the display control of the automatic operation plan. The link may be further divided and the automatic driving ratio may be calculated. Details of the automatic driving ratio determination method by the automatic driving ratio determination unit 115 will be described later with reference to the flowchart of FIG.

  In addition, even when there is a request for automatic driving ratio information from an in-vehicle device mounted on a vehicle other than the vehicle 100, the automatic driving ratio determining unit 115 performs the same processing. It is assumed that automatic driving ratio information is requested from the on-vehicle device 1 installed.

  Next, details of the travel history DB 22 will be described. FIG. 3 is a diagram illustrating a data structure example in the travel history DB 22. In the travel history DB 22, for example, a travel history of the vehicle 100 is recorded in a data structure as shown in FIG. In the data structure of FIG. 3, the travel history DB 22 is composed of a plurality of records, and has fields of vehicle ID 201, mesh ID 202, link ID 203, automatic driving element 204, operating condition 205, and automatic driving 206.

  In the vehicle ID 201, an ID number unique to the vehicle 100 is stored in common in each record. When the travel history of the vehicle 100 recorded in the travel history DB 22 is transmitted from the in-vehicle device 1 to the server 4, the server 4 refers to the value of the vehicle ID 201 included in the travel history, and from which vehicle is transmitted. It is possible to identify whether it is a running history.

  The mesh ID 202 and the link ID 203 store the map mesh corresponding to the record and the ID number of the link, respectively. In the example of FIG. 3, the vehicle 100 has already traveled on the links “L1” and “L2” belonging to the map mesh “M1”, and the travel history of these links is recorded in the travel history DB 22. . That is, each record in the travel history DB 22 corresponds to each link traveled by the vehicle 100. For the other links, information with the same data structure is recorded in the travel history DB 22.

  The automatic driving element 204 stores information on the type, function, performance, operation state, and the like of the automatic driving element when the vehicle 100 travels on the link corresponding to the record. In the example of FIG. 3, the types of cameras and radars in the surrounding environment detection device 5 mounted on the vehicle 100, information indicating the types of these hardware and software, and the in-vehicle device 1 mounted on the vehicle 100. Information indicating the type (version) of map data included in the automatic driving element 204 is stored. Note that the information stored in the automatic driving element 204 is not limited to the example of FIG. Any information can be stored in the automatic driving element 204 as long as the automatic driving element of the vehicle 100 can be appropriately classified.

  The operation condition 205 stores information on the operation condition of automatic driving when the vehicle 100 travels on the link corresponding to the record. In the example of FIG. 3, “early morning” that is information representing a time zone, “sunny” that is information representing weather, and “good” that is information representing road surface conditions are stored in the operation condition 205. . Note that the information stored in the operating condition 205 is not limited to the example of FIG. Any information can be stored in the operation condition 205 as long as the operation condition of the automatic operation can be appropriately classified.

  The automatic driving 206 stores information indicating whether the vehicle 100 travels on the link corresponding to the record by the automatic driving or the manual driving. In the example of FIG. 3, “◯” indicating that the vehicle has traveled in the automatic operation is stored in the automatic operation 206.

  In the travel history DB 22, a travel history of the vehicle 100 having the above data structure is recorded for each road and transmitted to the server 4. Note that the data structure of the travel history DB 22 shown in FIG. 3 is merely an example, and if the travel history indicating whether the vehicle 100 traveled on each road by automatic driving or manual driving can be appropriately recorded, Any data structure is possible. For example, instead of the mesh ID 202 and the link ID 203, latitude and longitude indicating the position of each road may be recorded. In this way, even when the plurality of in-vehicle devices that transmit the travel history to the server 4 have different map data structures, the server 4 can appropriately manage the travel history transmitted from each in-vehicle device. It becomes possible.

  Next, the details of the automatic driving history DB 121 will be described. FIG. 4 is a diagram illustrating a data structure example in the automatic driving history DB 121. In the automatic driving history DB 121, for example, automatic driving histories of a plurality of vehicles including the vehicle 100 are recorded with a data structure as shown in FIG. In the data structure of FIG. 4, the automatic driving history DB 121 is composed of a plurality of records, and has fields of mesh ID 301, link ID 302, automatic driving element 303, operating condition 304, and automatic driving history 305.

  In the mesh ID 301 and the link ID 302, similarly to the mesh ID 202 and the link ID 203 in FIG. 3, the map mesh and the link ID number corresponding to the record are stored, respectively. In the example of FIG. 4, a part of information recorded in the automatic driving history DB 121 is shown for the link “L1” belonging to the map mesh “M1”. For other links, information with the same data structure is recorded in the automatic driving history DB 121.

  Similar to the automatic driving element 204 of FIG. 3, the automatic driving element 303 stores information on the type, function, performance, etc. of the automatic driving element corresponding to the record. In the example of FIG. 4, the types of cameras and radars installed in each vehicle, information indicating the types of these hardware and software, and the types of map data possessed by the in-vehicle devices installed in each vehicle ( Version) is stored as the automatic driving element 303.

  In step S <b> 107, the control unit 10 determines whether or not a predetermined transmission condition for transmission of the travel history to the server 4 is satisfied. For example, after the travel route of the vehicle 100 is set in step S101 or the travel history is transmitted to the server 4 in the previous step S108, it is determined whether or not the vehicle 100 has traveled a certain distance. As a result, if the vehicle 100 has traveled a certain distance from the setting of the travel route or the transmission of the previous travel route, for example, 10 km, it is determined that the transmission condition has been satisfied, and the process proceeds to step S108. Otherwise, the process proceeds to step S109. move on. Note that the determination in step S107 may be performed according to other transmission conditions. For example, the determination in step S107 can be performed on the basis of the number of links through which the vehicle 100 has passed or the switching between automatic operation and manual operation.

  In step S <b> 108, the control unit 10 reads an unsent travel history from the travel history of the vehicle 100 recorded in the travel history DB 22 by the travel history recording unit 18 in step S <b> 106 and transmits it to the server 4 by the communication control unit 11.

Thereby, every time the vehicle 100 travels a certain distance, the history of the road on which the vehicle 100 traveled by automatic driving or manual driving is transmitted from the in-vehicle device 1 to the server 4.

  In step S109, the control unit 10 determines whether or not the vehicle 100 has arrived at the destination of the travel route set in step S101. If it has not arrived at the destination, it returns to Step S102, repeats processing after Step S102, and continues recording of a run history. On the other hand, if the destination has been reached, the process proceeds to step S110.

  In step S <b> 110, the control unit 10 notifies the server 4 that the vehicle 100 has arrived at the destination by the communication control unit 11. In addition, when the unsent travel history remains at this time, it is preferable to transmit to the server 4 together with the arrival notification to the destination. If step S110 is performed, the control part 10 will complete | finish the processing flow shown in FIG.

  FIG. 6 is a flowchart showing the operation of the server 4 when collecting the travel history in the information system according to the embodiment of the present invention. In this embodiment, the control part 110 of the server 4 will start the processing flow shown in FIG.

  In step S <b> 201, the control unit 110 determines whether a travel history is received from the in-vehicle device 1. When the travel history of the vehicle 100 is transmitted from the in-vehicle device 1 in step S108 of FIG. 5 and is received by the communication control unit 111, the received travel history is collected by the travel history collection unit 112, and the process proceeds to step S202.

  In step S202, the control unit 110 uses the automatic driving history recording unit 114 to identify a mesh and a link corresponding to the traveling history received in step S201. Here, based on the information on the travel links included in the received travel history, it is determined which link to which mesh belongs to which collected travel history. Note that when traveling histories are collected for a plurality of links, a mesh and a link are specified for each of the plurality of links.

  In step S203, the control unit 110 updates the automatic driving history DB 121 based on the traveling history received in step S201 by the automatic driving history recording unit 114. Here, using the mesh and link specified in step S202 and the information indicating the automatic driving element and the automatic driving operation condition included in the received driving history, which record in the automatic driving history DB 121 is the received driving history. Specify whether it corresponds to. Then, the automatic driving history of the vehicle 100 represented by the received driving history, that is, the value of the automatic driving history 305 of the specified record is updated according to whether the vehicle 100 has driven the link by automatic driving or manual driving. . Accordingly, the automatic driving history for each road can be appropriately classified and recorded in the automatic driving history 305 based on the traveling history of the vehicle 100 collected from the in-vehicle device 1.

  In step S204, control unit 110 determines whether vehicle 100 has arrived at the destination. When the arrival notification to the destination transmitted from the in-vehicle device 1 is received in step S110 of FIG. 5, it is determined that the vehicle 100 has arrived at the destination, and the processing flow shown in FIG. On the other hand, when the arrival notification at the destination has not been received, the process returns to step S201 and the above-described processing is repeated to continue the collection of the traveling history and the update of the automatic driving history DB 121.

  FIG. 7 is a flowchart showing the operation of the in-vehicle apparatus 1 when the automatic driving plan is displayed in the information system according to the embodiment of the present invention. In the present embodiment, the control unit 10 of the in-vehicle device 1 starts the processing flow shown in FIG. 7 when, for example, the user sets the destination of the vehicle 100 using the operation input unit 62 of the HMI device 6.

  In step S301, the control unit 10 sets the travel route of the vehicle 100 as in step S101 of FIG.

  In step S302, the control unit 10 reads the automatic driving element information 23 from the storage unit 20, and transmits it to the server 4 by the communication control unit 11 together with the travel route information indicating the travel route set in step S301. Thereby, the request | requirement of automatic driving | running | working ratio information is performed from the vehicle equipment 1 to the server 4. FIG.

  In step S <b> 303, the control unit 10 receives, from the server 4, the automatic driving ratio information transmitted according to the travel route information and the automatic driving element information 23 transmitted in step S <b> 302 by the communication control unit 11. This automatic driving ratio information represents the automatic driving ratio of each road existing on the travel route on which the vehicle 100 is scheduled to travel. Specifically, each vehicle having an automatic driving element having a function or performance equal to or less than that of the automatic driving element mounted on the vehicle 100 is operated under the same operating conditions as when the vehicle 100 traveled in the past. The ratio of driving on the road by automatic driving is expressed in link units. Details of the automatic driving ratio information will be described later with reference to the flowchart of FIG.

  In step S304, the control unit 10 causes the display control unit 14 to set a display mode corresponding to the automatic driving ratio information received in step S303 for each road on the travel route set in step S301. Here, for example, each road is classified into a predetermined number of groups according to the magnitude of the automatic driving ratio represented by the automatic driving ratio information, and a different display form is set for each group. In addition to this, an arbitrary display form can be set as long as the automatic driving ratio of each road on the travel route can be identified.

  In step S305, the control unit 10 controls the display control unit 14 to display the travel route set in step S301 on the map in the display form set in step S304. Here, the travel route from the current position to the destination is shown on the map displayed on the display unit 61 of the HMI device 6 according to the display form set in step S304. Thereby, the automatic driving plan of the vehicle 100 can be displayed with respect to the travel route, and when the vehicle 100 travels on the travel route, it can be shown to the user which road has a high possibility of automatic driving. If step S305 is performed, the control part 10 will complete | finish the processing flow shown in FIG.

  FIG. 8 is a flowchart showing the operation of the server 4 at the time of providing automatic driving ratio information in the information system according to the embodiment of the present invention. In the present embodiment, the control unit 110 of the server 4 receives the request for automatic driving ratio information by transmitting the travel route information and the automatic driving element information 23 from the in-vehicle device 1 in step S302 of FIG. The processing flow shown in FIG. 8 is started with the vehicle 100 on which the apparatus 1 is mounted as a target vehicle.

  In step S <b> 401, the control unit 110 receives the travel route information and the automatic driving element information 23 transmitted from the in-vehicle device 1 through the communication control unit 111. The received travel route information and the automatic driving element information 23 are temporarily stored in the storage unit 120 in the server 4 and used in the processing after step S402.

  In step S402, the control unit 110 selects a mesh and a link for which the automatic driving ratio determination unit 115 determines the automatic driving ratio. Here, based on the travel route information received in step S202, one of the links included in the travel route and the mesh to which the link belongs are selected. Thereby, each link of the travel route represented by the travel route information and the mesh to which the link belongs are selected one by one in a predetermined order, for example, from the current position to the destination.

  In step S <b> 403, the control unit 110 specifies the automatic driving operation condition corresponding to the mesh and link selected in step S <b> 402 by the automatic driving ratio determination unit 115. Here, the date and time when the vehicle 100 as the target vehicle travels the link is estimated, and the operation conditions such as the time zone, weather, and road surface condition corresponding to the date and time are retrieved from the operation condition information DB 122 and acquired. Alternatively, the automatic driving history corresponding to the mesh and the link selected in step S402 is specified in the automatic driving history DB 121, and the operating condition when the automatic driving history is most recently updated is determined, whereby the vehicle 100 is linked. You may specify the operating condition of the automatic driving | running | working from now on. Furthermore, by analyzing the automatic driving history DB 121 statistically, it is possible to estimate the operating conditions of automatic driving when the vehicle 100 will travel on the link from now on. For example, it is possible to obtain an estimation result that the road surface is frozen after heavy snow as an operating condition for automatic driving based on the weather yesterday or the present day. The automatic driving ratio determination unit 115 can specify the operating condition of automatic driving when the vehicle 100 travels the link by any method.

  In step S <b> 404, the control unit 110 uses the automatic driving ratio determination unit 115 to specify the configuration of the automatic driving element used for determining the automatic driving ratio. Here, based on the automatic driving element information 23 received in step S401, the configuration of the automatic driving element of the vehicle 100 that is the target vehicle is determined. Then, the configuration of the automatic driving element having a function or performance equal to or less than the determined automatic driving element of the vehicle 100 is specified as the configuration of the automatic driving element used for determining the automatic driving ratio. For example, it is assumed that the vehicle 100 has a camera and a radar as the surrounding environment detection device 5, and the version of the map DB 21 is a predetermined version. In this case, an automatic driving element having a combination of a camera and a radar similar to that of the vehicle 100 or only one of the camera and the radar and composed of map data of the same version as or older than the map DB 21. Is specified as the configuration of the automatic driving element used to determine the automatic driving ratio. At this time, it is preferable to determine the function and performance of the automatic driving element in consideration of the type of radar hardware and software. In the server 4, for example, information indicating the function and performance of a combination of various automatic driving elements is set in advance. By using this information, the automatic driving ratio determination unit 115 can specify the configuration of the automatic driving element used for determining the automatic driving ratio from the automatic driving element information 23.

  In step S405, the control unit 110 acquires the automatic driving history corresponding to the vehicle 100 from the automatic driving history DB 121 by using the processing results of steps S402, S403, and S404 by the automatic driving ratio determining unit 115. Specifically, the values of mesh ID 301 and link ID 302 correspond to the mesh and link selected in step S402, respectively, the value of automatic driving element 303 corresponds to the configuration of the automatic driving element specified in step S404, and operating condition 304 Each record corresponding to the operating condition identified in step S403 is identified in the automatic driving history DB 121. Then, by acquiring the value of the automatic driving history 305 of each specified record, the automatic driving history corresponding to the vehicle 100 that is the target vehicle can be acquired from the automatic driving history DB 121.

In step S406, the control unit 110 causes the automatic driving rate determination unit 115 to calculate an automatic driving rate for the link selected in step S402. Here, the automatic driving ratio of the link is calculated using the value of the automatic driving history 305 of each record acquired in step S405. Specifically, for example, it is assumed that “5/10”, “10/15”, and “3/11” are acquired as values of the automatic driving history 305 from three records corresponding to the same link, respectively. In this case, the automatic driving ratio of the link is calculated as follows by summing up the total value of the number of traveling vehicles and the number of vehicles traveling in the automatic driving.
(5 + 10 + 3) / (10 + 15 + 11) = 18/36 = 50%

  The automatic driving ratio corresponding to the vehicle 100 can be determined for each road by using the automatic driving history recorded in the automatic driving history DB 121 for the vehicle 100 that is the target vehicle by the processing of steps S402 to S406 described above. it can. At this time, the automatic driving ratio may be determined using only the automatic driving history recorded in the automatic driving history DB 121 within a predetermined time from the present time, for example, within one hour. In this way, it is possible to obtain an automatic driving ratio with a high real-time property.

  In step S407, the control unit 110 determines whether all the meshes and links corresponding to the travel route have been selected. If there are unselected meshes and links in step S402 in the travel route represented by the travel route information received in step S401, the process returns to step S402 to select a new mesh and link, and thereafter Repeat the process. Thereby, an automatic driving | running | working ratio is computable about all the links contained in a driving | running route. On the other hand, if it is determined in step S407 that all meshes and links have been selected, the process proceeds to step S408.

  In step S408, the control unit 110 creates automatic driving rate information indicating the automatic driving rate of each link calculated in step S406, and transmits the created automatic driving rate information to the in-vehicle device 1 by the communication control unit 111. Thereby, in response to a request from the in-vehicle device 1, automatic driving ratio information indicating the automatic driving ratio of each road corresponding to the travel route of the vehicle 100 is transmitted from the server 4 to the in-vehicle device 1, and in step S303 of FIG. Received by the in-vehicle device 1. If step S408 is performed, the control part 110 will complete | finish the processing flow shown in FIG.

In the in-vehicle device 1, in step S <b> 305 of FIG. 7, for example, a map screen as shown in FIG. 9 is displayed on the display unit 61 of the HMI device 6, whereby an automatic driving plan for the travel route of the vehicle 100 is presented to the user. .

  In the map screen 400 of FIG. 9, each road on the travel route from the current position 411 to the destination 412 is displayed in different colors as indicated by reference numerals 421 to 423. The display color 421 represents a road having the highest automatic driving ratio, for example, a road showing an automatic driving ratio of 80% or more. The display color 422 represents a road having the second highest automatic driving ratio, for example, a road showing an automatic driving ratio of 50% or more and less than 80%. The display color 423 represents a road having the lowest automatic driving ratio, for example, a road showing an automatic driving ratio of less than 50%. In addition, when the automatic driving | operation ratio with high real-time property is determined in the server 4 using the automatic driving | operation history within the predetermined time from the present as mentioned above, it is good also as a display form different from normal time. Furthermore, a normal automatic driving | running | working ratio and the automatic driving | running | working ratio with high real-time property may be compared, and when the difference is large, you may notify to a user.

  Further, a display switching button 413 is displayed on the map screen 400 of FIG. When the user performs an operation of selecting the display switching button 413 in the HMI device 6, the display on the display unit 61 is switched from the map screen 400 to a normal map screen, that is, a map screen that does not show the automatic driving ratio of each road. . Further, by displaying the display switching button 413 on the normal map screen after switching, it may be possible to return to the map screen 400 according to the user's operation. In this way, it is possible to perform map display according to the user's preference. Furthermore, at this time, priority may be given to the display of the map screen 400 if the vehicle 100 is in automatic driving, and priority may be given to the display of the normal map screen if the vehicle 100 is in manual driving. In this way, information useful for the user can be provided according to the driving state of the vehicle 100.

  Moreover, although embodiment demonstrated above demonstrated the example which notifies a user of the automatic driving | running | working ratio of each road contained in a driving route, when the driving route of the vehicle 100 is set in the vehicle-mounted apparatus 1, other than this was demonstrated. You may notify a user of an automatic driving | running | working ratio at a timing. For example, when the vehicle 100 is traveling toward the destination, characters and icons indicate the automatic driving ratio of the road on which the vehicle 100 is currently traveling in a predetermined notification area in the screen of the display unit 61 of the HMI device 60. The user may be notified of the above. Alternatively, the automatic driving ratio may be notified using voice or the like. Furthermore, when the automatic driving ratio changes greatly, it may be determined that there is a high possibility of switching from automatic driving to manual driving or vice versa, and the user may be notified.

  Moreover, although embodiment demonstrated above demonstrated the example which displays an automatic driving | operation ratio about one driving | running route from a present position to the destination, the number of driving | running routes is not limited to this. For example, a plurality of travel routes may be calculated according to the distance to the destination and time, and the automatic driving ratio may be displayed for each of the plurality of travel routes. Alternatively, the number of travel routes may be changed according to the distance to the destination, or the user may be able to select the number of travel routes.

  In the embodiment described above, the example in which the map screen 400 in which the travel route is color-coded according to the automatic driving ratio using the display colors 421 to 423 on the display unit 61 provided in the HMI device 60 has been described. In the external display device connected to 1, the travel route color-coded according to the automatic driving ratio may be displayed. As the external display device, for example, a HUD (Head-Up Display), a projection mapping onto a road surface, a wearable display device such as a glasses-type display, an aerial imaging display, or the like can be used. A display such as a smartphone, a tablet PC, or a notebook PC can also be used as an external display device.

  The embodiments and modifications described above are merely examples. As long as the characteristics of the present invention are not impaired, the present invention is not limited to the above-described embodiments, and other forms conceivable within the scope of the technical idea of the present invention are also included in the scope of the present invention. .
