When the map information 221 is updated, the update information is transmitted from the server 20 to the information processing apparatus 10.

  The map database 222 is a database generated by associating vehicle information with the map information 221. The map database 222 includes data in which vehicle information is associated with each of road links (road sections divided by intersections or the like), for example. In the map database 222, only part of the vehicle information may be associated with the road link. In the map database 222, information different from the vehicle information (for example, time zone classification such as morning, noon, or night) may be further associated with the road link. As an example, the map database 222 may include information that a vehicle having a medium vehicle size passes the road link AA1 at an average speed of 40 km by stepping on a brake three times.

  The vehicle information acquisition unit 231 acquires vehicle information from the information processing apparatus 10 mounted on one or more vehicles that use the driving support system 1.

  The map database generation unit 232 generates the map database 222 by associating the vehicle information acquired by the vehicle information acquisition unit 231 with the map information 221. In the present embodiment, the map database generation unit 232 generates the map database 222 by associating the vehicle information with the road link of the corresponding map information 221 based on the position information 153 included in the vehicle information.

  When the information providing unit 233 detects that a predetermined operation for designating a road is performed by one user of the vehicle, the information providing unit 233 obtains braking information 154 and speed information 155 associated with the road from the map database 222.

Moreover, the information provision part 233 grasps | ascertains the vehicle rank of one user's vehicle from vehicle information. The information providing unit 233 extracts data from the map database 222 on the condition of the road link of the road designated by one user and the vehicle grade of the one user's vehicle. Then, the information providing unit 233 provides the extracted results (braking information 154 and speed information 155) to one user as route information.

  Here, the server control unit 23 loads a program stored in the server storage unit 22 and executes the program, thereby at least one of the vehicle information acquisition unit 231, the map database generation unit 232, and the information provision unit 233. The function of the part can be realized.

  FIG. 4 illustrates a state in which a user performs a predetermined operation for requesting route information from the server 20 functioning as a route information providing device, using the information processing device 10 functioning as a navigation device. FIG. 5 exemplifies route information shown in the information processing apparatus 10.

  As illustrated in FIGS. 4 and 5, the information processing apparatus 10 that functions as a navigation apparatus displays a map on a touch panel display (corresponding to the display unit 11 and the input unit 12). In addition, the information processing apparatus 10 displays a main bar 101 that displays the place name and time of the current position. The information processing apparatus 10 also shows a menu bar 102 that enables various settings of the navigation apparatus. Further, the information processing apparatus 10 displays an enlargement / reduction icon 103 that enables enlargement / reduction of the map. In addition, the information processing apparatus 10 displays a voice guidance icon 104 that turns on or off a voice guidance function.

  As shown in FIG. 4, the user taps one road 105 on the map on the touch panel display. In the present embodiment, the operation of tapping the road 105 corresponds to a predetermined operation for designating the road. The predetermined operation becomes a trigger for requesting route information from the server 20.

  The information providing unit 233 of the server 20 detects that a predetermined operation has been executed via the server communication unit 21. Then, the information providing unit 233 of the server 20 extracts data from the map database 222 on the condition of the road link designated by the user and the vehicle grade of the user's vehicle. Then, the information providing unit 233 of the server 20 transmits the extracted results (braking information 154 and speed information 155) to the information processing apparatus 10 as route information.

  As illustrated in FIG. 5, the information processing apparatus 10 displays the acquired route information 106 on the touch panel display. The route information 106 is a record of travel when the vehicles of other users (user X, user Y, and user Z) travel on the road 105. Here, the vehicle grade of the other user's vehicle of the route information 106 is the same as the vehicle grade of the user's vehicle that requested the route information 106. For example, when the vehicle grade of the user's vehicle that requested the route information 106 is a medium size, the route information 106 shows a record of the travel of a vehicle of the same medium size. Here, the traveling records of the user X, the user Y, and the user Z can be switched by tapping the tab on which the user name is written.

  In the example of FIG. 5, the user X's vehicle travels on the road 105 at an average speed of 50 km / h. Further, the vehicle of the user X is stepping on the brake on the road 105 ten times. The user who has requested the route information 106 can confirm that a vehicle of the same vehicle type has traveled at a sufficiently high speed without frequently stepping on the brake. Therefore, the user who has requested the route information 106 can determine that the road 105 can be selected as the travel route.

  As another example, when the route information 106 indicates that many users are traveling on the road 105 at an average speed of 10 km / h or less and stepping on the brake 50 times or more, It can be determined that 105 is narrower than the vehicle size of the own vehicle and should not be selected as the travel route.

  In this way, the user can determine whether the road 105 can be an appropriate travel route based on the route information 106 that is a travel record of another vehicle of the same vehicle type before actually passing the road 105. .

(Operation flow of the route information providing device)
FIG. 6 is a flowchart showing the operation of the server 20 functioning as a route information providing apparatus.

  The server control unit 23 of the server 20 provides the user with the route information 106 obtained by the above method (step S4).

  When the server control unit 23 of the server 20 does not detect that a predetermined operation for requesting the route information 106 has been executed by the user (No in Step S3), or after the process in Step S4, a series of processes Exit.

  As described above, according to the route information providing apparatus according to the present embodiment, when the information providing unit 233 detects that a predetermined operation for designating a road is performed by one user of the vehicle, the map is provided. The braking information 154 and the speed information 155 associated with the road are selected from the database 222 according to the vehicle grade of one user's vehicle, and provided as one route information 106 to the one user. The user can know the braking information 154 and the speed information 155 of the vehicle of the same vehicle type on the road as the route information 106. The user can determine whether or not the designated road can be an appropriate travel route based on such route information 106. In other words, the user can determine whether or not the designated road can be an appropriate travel route based on the past travel history of other vehicles of the same vehicle type. That is, according to the route information providing apparatus according to the present embodiment, the route information 106 can be appropriately provided according to the vehicle grade.

  Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various variations and modifications based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, functions or the like included in each means or each step can be rearranged so that there is no logical contradiction, and a plurality of means or steps can be combined or divided into one. .

  For example, in the present embodiment described above, the route information 106 may display one of the braking information 154 and the speed information 155. Further, the braking information 154 may be the number of emergency brakings instead of the total number of brakings. The speed information 155 may be the maximum speed instead of the average speed.
