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

The in-vehicle device 1 includes an ambient environment detection device 5 which is a device for detecting the surrounding environment of the vehicle 100, an HMI device 6 which provides an interface between the in-vehicle device 1 and a user, and various processes and controls related to the running of the vehicle 100. The vehicle control device 7 is connected to the vehicle control device 7 via an in-vehicle communication network 8 provided in the vehicle 100. The in-vehicle communication network 8 is, for example, 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 possessed by the vehicle-mounted device 1 via the vehicle-mounted communication network 8, and uses these to control the driving of the vehicle 100. This makes it possible to automatically drive the vehicle 100 by substituting a part or all of the driving operation performed by the user. 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 on, for example, in front of, behind, on both the left and right sides of the vehicle 100, and transmits the radio waves, infrared rays, sound waves, and the like to the surroundings of the vehicle 100 to capture the surroundings of the vehicle 100. It is realized by a radar, LiDAR (Light Detection and Ranging), sonar, etc. that detect the surrounding environment of the vehicle 100 by receiving the reflected wave. In the following, LiDAR using light such as infrared rays and sonar using sound waves will also be described as a type of radar. The vehicle control device 7 is, for example, an ECU (Electronic Control Unit), and various types of the vehicle control device 7 are mounted on the vehicle 100 according to its function and control target.

The vehicle control device 7 acquires surrounding environment information from the surrounding environment detection device 5 via the vehicle-mounted communication network 8, and also acquires map information near the current position of the vehicle 100 from the vehicle-mounted 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 differs depending on the type of the ambient environment detection device 5. When an obstacle exists 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 ambient environment information. On the other hand, the map information near the current position of the vehicle 100 acquired from the vehicle-mounted device 1 includes information indicating the shape, width, number of lanes, and the like of the road on which the vehicle 100 is traveling.

Any information can be stored in the operating condition 304 as long as the operating conditions of the automatic operation can be appropriately classified.

In the automatic driving history 305, the total value of the number of vehicles running and the number of vehicles traveled by automatic driving are stored as information representing the automatic driving history corresponding to the record. For example, in the first record, "10/10" is recorded in the automatic operation history 305. This is because 10 vehicles have been driven on the link specified by the mesh ID 301 and the link ID 302 in a situation where the vehicle matching the automatic driving element 303 meets the operating condition 304, and all 10 vehicles are automatically driven. It indicates that the vehicle was driven. For other records, the total number of vehicles traveled and the number of vehicles traveled by automatic driving are recorded in the automatic driving history 305 in the same format.

In the automatic driving history DB 121, the automatic driving history based on the above data structure is recorded for each road for a plurality of vehicles including the vehicle 100. The data structure of the automatic driving history DB 121 shown in FIG. 4 is just an example, and any data structure can be used as long as the automatic driving history of each vehicle can be appropriately recorded.

Next, the operation contents of the in-vehicle device 1 and the server 4 when providing information to the user will be described. FIG. 5 is a flowchart showing the operation of the in-vehicle device 1 at the time of traveling history recording in the information system according to the embodiment of the present invention. In the present embodiment, the control unit 10 of the vehicle-mounted device 1 starts the processing flow shown in FIG. 5, for example, when the user sets the destination of the vehicle 100 using the operation input unit 62 of the HMI device 6.

In step S101, the control unit 10 sets the travel route of the vehicle 100. At this time, the control unit 10 acquires the current position from the current position detection unit 30 by the current position acquisition unit 13. Then, the route setting unit 17 calculates the route from the current position to the destination using the map DB 21, and sets the calculation result in the traveling route of the vehicle 100. Alternatively, as described above, the travel route may be set using the information acquired from the other device or the server 4, or the travel route information already set may be acquired from the other device or the server 4.

In step S102, the control unit 10 acquires the current position from the current position detection unit 30 by the current position acquisition unit 13, and uses the map DB 21 to specify the link in which the vehicle 100 is currently traveling as a travel link.

In step S103, the control unit 10 acquires the automatic driving state of the vehicle 100. Here, the transmission information of the vehicle control device 7 is acquired by using the in-vehicle communication interface unit 15, and based on the information, it is determined whether or not the vehicle 100 is automatically driven under the control of the vehicle control device 7, and the transmission information thereof is determined. The determination result is acquired as the automatic driving state of the vehicle 100.

In step S104, the control unit 10 acquires the automatic operation element information 23. Here, the automatic driving element information acquisition unit 12 acquires the above-mentioned information from the surrounding environment detection device 5 and the map DB 21, and stores the information as the automatic driving element information 23 in the traveling link of the vehicle 100 specified in step S102. Record at 20.

In step S105, the control unit 10 specifies the operating conditions for automatic operation. Here, the operating condition specifying unit 16 specifies the operating conditions such as the time zone, the weather, and the road surface condition at the traveling link of the vehicle 100 specified in step S102 by the method as described above.

In step S106, the control unit 10 uses the travel history recording unit 18 to identify the travel link in step S102, the automatic operation state and automatic operation element information 23 acquired in steps S103 and S104, respectively, and the automatic operation specified in step S105. The traveling history of the vehicle 100 is recorded in the traveling history DB 22 based on the operating conditions of driving. Here, using the data structure as illustrated in FIG. 3, the travel history DB 22 is a combination of the information representing the travel link and the information indicating whether the vehicle 100 is traveling in the automatic driving or the manual driving at the travel link. Record in. By repeating this process for each travel link, the travel history representing the history of the road on which the vehicle 100 has traveled by automatic driving or manual driving is recorded in the traveling history DB 22 in the in-vehicle device 1.

In step S107, the control unit 10 determines whether or not a predetermined transmission condition for transmitting the travel history to the server 4 is satisfied. For example, after setting the travel route of the vehicle 100 in step S101 or transmitting the travel history 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 travels a certain distance, for example, 10 km from the setting of the travel route or the transmission of the previous travel route, it is determined that the transmission condition is satisfied and the process proceeds to step S108. If not, the process proceeds to step S109. move on. The determination in step S107 may be performed according to other transmission conditions. For example, it is possible to make the determination in step S107 on the transmission condition that the number of links passed by the vehicle 100 and the switching between automatic driving and manual driving have been performed.

In step S108, the control unit 10 reads out the untransmitted travel history of the travel history of the vehicle 100 recorded in the travel history DB 22 by the travel history recording unit 18 in step S106, and transmits it to the server 4 by the communication control unit 11. do. As a result, every time the vehicle 100 travels a certain distance, the history of the road on which the vehicle 100 has traveled by automatic driving or manual driving is transmitted from the vehicle-mounted 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 the vehicle has not arrived at the destination, the process returns to step S102, and the processes after step S102 are repeated to continue recording the travel history. On the other hand, when arriving at the destination, the process proceeds to step S110.

In step S110, the control unit 10 notifies the server 4 that the vehicle 100 has arrived at the destination by the communication control unit 11. If there is an untransmitted travel history at this time, it is preferable to transmit it to the server 4 together with the arrival notification to the destination. After executing step S110, the control unit 10 ends the processing flow shown in FIG.

FIG. 6 is a flowchart showing the operation of the server 4 at the time of collecting the traveling history in the information system according to the embodiment of the present invention. In the present embodiment, the control unit 110 of the server 4 starts the processing flow shown in FIG. 6 when the traveling of the vehicle 100 is started.

In step S201, the control unit 110 determines whether or not the travel history has been received from the vehicle-mounted device 1. When the travel history of the vehicle 100 is transmitted from the vehicle-mounted 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 is performed in step S202. Proceed. On the other hand, if the travel history has not been received, the process proceeds to step S204.

In step S202, the control unit 110 identifies the mesh and the link corresponding to the travel history received in step S201 by the automatic operation history recording unit 114. Here, based on the information of the travel link included in the received travel history, it is determined which link the collected travel history corresponds to which mesh belongs to. When the travel history is collected for a plurality of links, the mesh and the link are specified for each of the plurality of links.

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

In step S204, the control unit 110 determines whether or not the 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. 6 is terminated. On the other hand, if the arrival notification to the destination has not been received, the process returns to step S201 and the above-mentioned processing is repeated to continue collecting the traveling history and updating the automatic driving history DB 121.

FIG. 7 is a flowchart showing the operation of the in-vehicle device 1 at the time of displaying the automatic operation plan in the information system according to the embodiment of the present invention. In the present embodiment, the control unit 10 of the vehicle-mounted device 1 starts the processing flow shown in FIG. 7, for example, when 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 traveling route of the vehicle 100 in the same manner 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 representing the travel route set in step S301. As a result, the in-vehicle device 1 requests the server 4 for the automatic driving ratio information.

In step S303, the control unit 10 receives from the server 4 the travel route information transmitted in step S302 and the automatic driving ratio information transmitted according to the automatic driving element information 23 by the communication control unit 11. This automatic driving ratio information represents the automatic driving ratio of each road existing on the traveling route where the vehicle 100 is going to travel. Specifically, each vehicle equipped with an automatic driving element having a function or performance equal to or lower than that of the automatic driving element mounted on the vehicle 100 is under the same operating conditions as when the vehicle 100 has been driven in the past. It shows the ratio of driving on the road by automatic driving in units of links. The details of the automatic operation ratio information will be described later with reference to the flowchart of FIG.

In step S304, the control unit 10 sets the display mode according to the automatic driving ratio information received in step S303 for each road on the travel route set in step S301 by the display control unit 14. 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 different display forms are set for each group. In addition to this, if the automatic driving ratio of each road on the traveling route can be identified, any display form can be set.

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, according to the display mode set in step S304, the traveling route from the current position to the destination is shown on the map displayed on the display unit 61 of the HMI device 6. Thereby, the automatic driving plan of the vehicle 100 can be displayed on the traveling route, and when the vehicle 100 travels on the traveling route, it is possible to show the user on which road the possibility of automatic driving is high. After executing step S305, the control unit 10 ends the processing flow shown in FIG. 7.

FIG. 8 is a flowchart showing the operation of the server 4 at the time of providing the automatic operation ratio information in the information system according to the embodiment of the present invention. In the present embodiment, when the control unit 110 of the server 4 requests the automatic driving ratio information by transmitting the traveling route information and the automatic driving element information 23 from the vehicle-mounted device 1 in step S302 of FIG. 7, the vehicle-mounted unit 110 is mounted on the vehicle. The processing flow shown in FIG. 8 is started with the vehicle 100 on which the device 1 is mounted as the target vehicle.

In step S401, the control unit 110 receives the travel route information and the automatic driving element information 23 transmitted from the vehicle-mounted device 1 by the communication control unit 111. The received travel route information and automatic driving element information 23 are temporarily stored in the storage unit 120 in the server 4, and are used in the processes after step S402.

In step S402, the control unit 110 selects a mesh and a link for which the automatic operation ratio determination unit 115 determines the automatic operation ratio. Here, one of the links included in the travel route and the mesh to which the link belongs are selected based on the travel route information received in step S202. As a result, 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 S403, the control unit 110 specifies the operating conditions for automatic operation corresponding to the mesh and the link selected in step S402 by the automatic operation ratio determination unit 115. Here, the date and time when the vehicle 100, which is the target vehicle, travels on the link is estimated, and the operating conditions such as the time zone, the weather, and the road surface condition corresponding to the date and time are searched and acquired from the operating condition information DB 122. Alternatively, the vehicle 100 identifies the automatic driving history corresponding to the mesh and the link selected in step S402 in the automatic driving history DB 121, and determines the operating conditions when the automatic driving history is recently updated, whereby the vehicle 100 has the link. You may specify the operating condition of the automatic driving when traveling from now on. Further, by statistically analyzing the automatic driving history DB 121, it is possible to estimate the operating conditions for automatic driving when the vehicle 100 is about to travel on the link. For example, based on yesterday's and current weather conditions, it is possible to obtain an estimation result that the road surface is frozen after heavy snowfall as an operating condition for autonomous driving. The automatic driving ratio determination unit 115 can specify the operating conditions for automatic driving when the vehicle 100 travels on the link by any of these methods.

In step S404, the control unit 110 specifies the configuration of the automatic operation element used for determining the automatic operation ratio by the automatic operation ratio determination unit 115. Here, based on the automatic driving element information 23 received in step S401, the configuration of the automatic driving element possessed by the vehicle 100, which is the target vehicle, is determined. Then, the configuration of the automatic driving element having the same or lower function and performance as 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 autonomous driving element that has the same camera and radar combination as the vehicle 100, or has only one of the camera and radar, and is composed of map data of the same or older version as the map DB 21. Is specified as the configuration of the automatic driving element used for determining 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. Information indicating the function and performance of various combinations of automatic driving elements is preset in the server 4. 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 the automatic driving ratio determination unit 115 using the processing results of steps S402, S403, and S404. Specifically, the values of the mesh ID 301 and the link ID 302 correspond to the mesh and the link selected in step S402, respectively, and the value of the automatic operation element 303 corresponds to the configuration of the automatic operation element specified in step S404, and the operating condition 304 Each record whose value of is corresponding to the operating condition specified in step S403 is specified in the automatic operation 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 which is the target vehicle can be acquired from the automatic driving history DB 121.

In step S406, the control unit 110 calculates the automatic operation ratio for the link selected in step S402 by the automatic operation ratio determination unit 115. Here, the automatic operation ratio of the link is calculated using the value of the automatic operation 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 the values of the automatic operation history 305 from three records corresponding to the same link. In this case, the automatic driving ratio of the link is calculated as follows by summing up the total number of vehicles and the number of vehicles traveling by automatic driving.
(5 + 10 + 3) / (10 + 15 + 11) = 18/36 = 50%

By the processing of steps S402 to S406 described above, it is possible to determine the automatic driving ratio corresponding to the vehicle 100 for each road by using the automatic driving history recorded in the automatic driving history DB 121 for the vehicle 100 which is the target vehicle. 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, for example, within one hour. In this way, it is possible to obtain a highly real-time automatic driving ratio.

In step S407, the control unit 110 determines whether or not all the meshes and links corresponding to the travel path have been selected. If there is an unselected mesh and link 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 then steps S403 and subsequent steps. Repeat the process. As a result, the automatic driving ratio can be calculated for all the links included in the traveling route. On the other hand, if it is determined in step S407 that all the meshes and links have been selected, the process proceeds to step S408.

In step S408, the control unit 110 creates automatic operation ratio information representing the automatic operation ratio of each link calculated in step S406, and transmits the created automatic operation ratio information to the vehicle-mounted device 1 by the communication control unit 111. As a result, in response to the request from the in-vehicle device 1, the automatic driving ratio information representing the automatic driving ratio of each road corresponding to the traveling 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. After executing step S408, the control unit 110 ends the processing flow shown in FIG.

FIG. 9 is a diagram showing an example of a display screen of an automatic driving plan displayed on the vehicle-mounted device 1. In the in-vehicle device 1, in step S305 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, so that an automatic driving plan for the travel route of the vehicle 100 is presented to the user. ..

On the map screen 400 of FIG. 9, each road on the traveling 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 rate, for example, a road showing an automatic driving rate of less than 50%. When the automatic operation ratio with high real-time property is determined by using the automatic operation history within a predetermined time from the present on the server 4 as described above, the display form may be different from the normal time. Further, the normal automatic driving ratio and the highly real-time automatic driving ratio may be compared, and if the difference is large, the user may be notified.

Further, on the map screen 400 of FIG. 9, the display switching button 413 is displayed. When the user performs an operation of selecting the display switching button 413 on the HMI device 6, the display of the display unit 61 is switched from the map screen 400 to a normal map screen, that is, a map screen in which the automatic driving ratio of each road is not shown. .. Further, by displaying the display switching button 413 even on the normal map screen after switching, it may be possible to return to the map screen 400 according to the user's operation. By doing so, it is possible to display the map according to the user's preference. Further, at this time, if the vehicle 100 is in automatic driving, the display of the map screen 400 may be prioritized, and if the vehicle 100 is in manual driving, the display of the normal map screen may be prioritized. By doing so, it is possible to provide useful information to the user according to the driving state of the vehicle 100.

According to one embodiment of the present invention described above, the following effects are exhibited.

(1) The in-vehicle device 1 mounted on the vehicle 100 capable of automatic driving includes a communication control unit 11 and a display control unit 14. The communication control unit 11 transmits the automatic driving element information 23 indicating the type of the automatic driving element used for automatic driving in the vehicle 100 to the server 4 (step S302 in FIG. 7), and automatically for each road according to the automatic driving element. The automatic operation ratio information representing the operation ratio is received from the server 4 (step S303 in FIG. 7). The display control unit 14 controls to display the automatic driving plan of the vehicle 100 on the display unit 61 of the HMI device 6 based on the automatic driving ratio information received by the communication control unit 11 (steps S304 and S305 in FIG. 7). By doing so, it is possible to accurately notify the user of the automatic driving plan for the road that the vehicle 100 is going to take.

(2) The automatic driving element includes an ambient environment detection device 5 that detects the ambient environment of the vehicle 100, and a map DB 21 that is map data of the road on which the vehicle 100 travels. The automatic operation element information 23 includes information representing the type of the ambient environment detection device 5 and information representing the type of the map DB 21. Since this is done, the automatic driving element information 23 can be used to accurately notify the server 4 of the automatic driving element mounted on the vehicle 100.

(3) The in-vehicle device 1 includes a route setting unit 17 that sets a travel route to the destination of the vehicle 100. In step S303, the communication control unit 11 receives automatic driving ratio information from the server 4 for each road included in the travel route set by the route setting unit 17. Since this is done, the information on the automatic driving ratio of the road on which the vehicle 100 is about to travel can be reliably received from the server 4 as the automatic driving ratio information.

(4) In steps S304 and S305, the display control unit 14 causes the display screen such as the map screen 400 of FIG. 9 to display an automatic driving plan showing the possibility that the vehicle 100 can be driven by automatic driving for each road. Take control. By doing so, it is possible to inform the user in an easy-to-understand manner of the automatic driving plan for the road that the vehicle 100 is going to pass.

(5) The in-vehicle device 1 includes a travel history recording unit 18 that records a travel history representing the history of the road on which the vehicle 100 has traveled by automatic driving or manual driving in the travel history DB 22 (step S106 in FIG. 5). The communication control unit 11 transmits the travel history recorded by the travel history recording unit 18 to the server 4 (step S108 in FIG. 5). Since this is done, the information necessary for the server 4 to generate the automatic operation ratio information can be provided to the server 4, and the accuracy of the automatic operation ratio information can be improved.

(6) The server 4 can be connected to a plurality of vehicle-mounted devices mounted on each of a plurality of vehicles capable of automatic driving, in addition to the vehicle-mounted device 1 mounted on the vehicle 100. The server 4 includes a travel history collection unit 112, an automatic operation history recording unit 114, an automatic operation ratio determination unit 115, and a communication control unit 111. The travel history collection unit 112 collects travel histories representing the histories of roads traveled by a plurality of vehicles by automatic driving or manual driving from a plurality of in-vehicle devices (step S201 in FIG. 6). The automatic driving history recording unit 114 is based on the types of automatic driving elements used for automatic driving in each of the plurality of vehicles and the driving history of the plurality of vehicles collected by the traveling history collecting unit 112, for each road of the plurality of vehicles. The automatic operation history of the above is recorded in the automatic operation history DB 121 (step S203 in FIG. 6). The automatic driving ratio determination unit 115 targets any of a plurality of vehicles, for example, the vehicle 100, and automatically corresponds to the vehicle 100 by using the automatic driving history of the automatic driving history DB 121 recorded by the automatic driving history recording unit 114. The driving ratio is determined for each road (steps S405 and S406 in FIG. 8). The communication control unit 111 transmits the automatic driving ratio information representing the automatic driving ratio for each road determined by the automatic driving ratio determining unit 115 to the in-vehicle device 1 of the vehicle 100 (step S408 in FIG. 8). Since this is done, the server 4 can provide the in-vehicle device 1 with information for accurately notifying the user of the automatic driving plan for the road that the vehicle 100 is going to take.

(7) The automatic driving ratio determination unit 115 identifies an automatic driving element having a function and / or performance equal to or less than that of the automatic driving element of the vehicle 100 (step S404 in FIG. 8), and the vehicle provided with this automatic driving element. The automatic driving history recorded based on the driving history of the above is acquired from the automatic driving history DB 121 (step S405 in FIG. 8). In step S406, the automatic driving ratio corresponding to the vehicle 100 is determined by using the automatic driving history acquired in this way. Since this is done, the automatic driving ratio can be accurately determined in consideration of the functions and performances of the automatic driving elements mounted on the vehicle 100.

(8) The automatic driving history recording unit 114 records the automatic driving history in step S203 for each operating condition of automatic driving when a plurality of vehicles each travel on the road on which the driving history collecting unit 112 has collected the driving history. .. The automatic driving ratio determination unit 115 identifies the operating conditions for automatic driving when the vehicle 100 travels on the road (step S403 in FIG. 8), and uses the automatic driving history recorded corresponding to the operating conditions. The automatic driving ratio corresponding to the vehicle 100 is determined in step S405. Since this is done, the automatic driving ratio can be accurately determined in consideration of the operating conditions of the automatic driving when the vehicle 100 is running.

(9) It is preferable that the operating conditions for automatic driving include at least one of a time zone, weather conditions, and road surface conditions. By doing so, it is possible to appropriately express the event that affects the operation of the automatic driving.

(10) The automatic driving element of the vehicle 100 preferably includes an ambient environment detection device 5 for detecting the surrounding environment of the vehicle 100 and a map DB 21 representing map data of the road on which the vehicle 100 travels. In this way, the elements necessary for realizing automatic driving can be appropriately expressed as automatic driving elements.

(11) In step S408 of FIG. 8, the communication control unit 111 of the server 4 transmits automatic driving ratio information to the vehicle-mounted device 1 of the vehicle 100 for each road included in the travel route to the destination of the vehicle 100. Since this is done, the server 4 can provide the in-vehicle device 1 with information representing an automatic driving plan that is useful when the vehicle 100 travels toward the destination.

In the embodiment described above, an example has been described in which the automatic driving ratio of each road included in the driving route can be identified by displaying the traveling route to the destination in different colors according to the automatic driving ratio. Instead of the color-coded display, for example, the shade and brightness of the color, the thickness and type of the line, the blinking speed, and the like may be changed according to the automatic driving ratio so that the automatic driving ratio of each road can be identified. Alternatively, the user may be notified of the automatic driving ratio of each road included in the traveling route by using characters or icons.

Further, in the embodiment described above, when the traveling route of the vehicle 100 is set in the in-vehicle device 1, an example of notifying the user of the automatic driving ratio of each road included in the traveling route has been described, but other than this. The automatic operation ratio may be notified to the user at the timing. For example, when the vehicle 100 is traveling toward a destination, characters or 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 by such means. Alternatively, the automatic driving ratio may be notified by voice or the like. Further, when the ratio of automatic driving changes significantly, it may be determined that there is a high possibility of switching from automatic driving to manual driving, or conversely, from manual driving to automatic driving, and the user may be notified.

Further, in the embodiment described above, an example of displaying the automatic driving ratio for one traveling route from the current position to the destination has been described, but the number of traveling routes is not limited to this. For example, a plurality of traveling routes may be calculated according to the distance and time to the destination, and the automatic driving ratio may be displayed for each of the plurality of traveling 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.
