[0011] Hereinafter, embodiments of the present disclosure will be described in detail with appropriate reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed descriptions of well-known matters and redundant descriptions of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] (Embodiment 1) FIG. 1 is a conceptual diagram for explaining the updating of road information according to the first embodiment.

[0013] The widespread adoption of autonomous driving and the realization of digital twins of cities require the collection of road information that shows the conditions of roads and their surroundings. However, road information collected long ago does not accurately reflect the current conditions of roads and their surroundings, which hinders its use. Therefore, old road information needs to be updated with the latest road information. For example, in Figure 1, if the road information for road R1 has expired, the road information for road R1 needs to be updated with the latest road information.

[0014] While traveling on road R1, vehicle 10 acquires vehicle external information, which is information indicating the conditions of road R1 and its surroundings, and transmits it to server 20 (see FIG. 2). Server 20 updates the road information of road R1 based on the vehicle external information collected from vehicle 10.

[0015] However, for example, if the traffic volume on road R1 is low, vehicles 10 may not travel on road R1, and the server 20 may not be able to update the road information for the expired road R1 to the latest road information for a long period of time.

[0016] Therefore, in this embodiment, a road information collection system 1 (see FIG. 2) and a method for more efficiently updating road information of expired roads to the latest road information will be described. The road information may include various information such as 3D map data of a predetermined section of the road, roadside scenery, obstacles, weather, and the number of people.

[0017] <System configuration> FIG. 2 is a block diagram showing an example of the configuration of the road information collection system 1 according to the first embodiment.

[0018] The road information collection system 1 includes at least one vehicle 10 and a server 20. The vehicle 10 and the server 20 can transmit and receive data via a predetermined communication network 3. Examples of the communication network 3 include a cellular communication network (LTE, 4G, 5G, etc.), satellite communication, an ITS spot, or a wireless LAN.

[0019] The vehicle 10 includes a communication device 11, a positioning sensor 12, a vehicle control device 13, an electronic wallet 14, an IVI device 15, and an external information acquisition device 16. These devices may be connected to an in-vehicle network 17 and be able to send and receive information to and from each other. Examples of the in-vehicle network 17 include a Controller Area Network (CAN), a Local Interconnect Network (LIN), FlexRay, a Gigabit Video Interface (GVIF), a PFD-LINK, and a Gigabit Multimedia Serial Link (GMSL).

[0020] The communication device 11 is a device (for example, a wireless communication circuit) that connects to the communication network 3 and controls the transmission and reception of data. The communication device 11 includes a transmitting device that controls the transmission of data and a receiving device that controls the reception of data.

[0021] The positioning sensor 12 receives a positioning signal from, for example, Global Navigation Satellite Systems (GNSS) and determines the current position of the vehicle 10.

[0022] The vehicle control device 13 is a device that controls the traveling of the vehicle 10. The vehicle control device 13 obtains, for example, information on the traveling speed, acceleration, deceleration, and information on moving forward, backward, turning right, turning left, etc. of the vehicle 10.

[0023] The electronic wallet 14 holds and manages points, which are an example of incentives. Details of the incentives and points will be described later, but the user of the vehicle 10 is given points according to their contribution to the collection of expired road information, and the electronic wallet 14 holds and manages the points.

[0024] The IVI device 15 provides various information to the user of the vehicle 10. IVI stands for "In-Vehicle Infotainment." The IVI device 15 may include a car navigation function. For example, the IVI device 15 navigates to a destination. The IVI device 15 is connected to an input device 18 and a display device 19. The IVI device 15 may be a device with a touch panel integrated with the input device 18 and the display device 19, or a user's mobile terminal. Alternatively, the IVI device 15 may be a device integrated with the display device 19, and the input device 18 may be a separate touchpad. If the IVI device 15 is a mobile terminal, the communication device 11 may be built into the mobile terminal.

[0025] The external information acquisition device 16 is mounted on the vehicle 10 and acquires vehicle external information indicating the conditions of the road and its surroundings. The external information acquisition device 16 may include a camera mounted on the vehicle 10 and acquiring external video. The camera may be a 360-degree camera. Alternatively, the camera may be mounted on a mobile terminal. In the following description, the video captured by the camera may be referred to as "exterior vehicle video." The external information acquisition device 16 may include a sonar mounted on the vehicle 10 and detecting external obstacles using sound waves. The external information acquisition device 16 may include a radar mounted on the vehicle 10 and detecting external obstacles using electromagnetic waves. The external information acquisition device 16 may include a speedometer mounted on the vehicle 10 and detecting the speed of the vehicle 10. The external information acquisition device 16 may include an accelerometer mounted on the vehicle 10 and detecting the acceleration of the vehicle 10. The external information acquisition device 16 may include an angular accelerometer mounted on the vehicle 10 and detecting the angular acceleration of the vehicle 10. In the following description, the sonar, radar, speedometer, accelerometer, or values ​​detected by each accelerometer may be referred to as sensor values. The vehicle external information may include, in association with each other, position information measured by the positioning sensor 12, the time at which the position was measured, an image of the outside of the vehicle captured at that position, and a sensor value detected at that position.

[0026] The server 20 includes a control device 21, a communication device 22, a map DB 23, a contribution task DB 24, a data analysis device 25, and an electronic wallet 26. DB stands for "Database." These devices are connected to a bus 27 and may transmit and receive data to and from each other.

[0027] The control device 21 executes processing to realize the functions of the server 20. The control device 21 may include a processor and volatile or non-volatile memory. The processor may then execute a predetermined computer program stored in the memory to realize the functions of the server 20.

[0028] The communication device 22 is a device that connects to the communication network 3 and controls the transmission and reception of data.

[0029] The map DB 23 manages road maps used for route searches as a database. The map DB 23 also manages road information for each road and its expiration date. The road information includes, for example, 3D map information for the road and its surroundings, obstacle information such as construction, weather, and disasters, and update dates and times of these. The map DB 23 may be configured in non-volatile storage (for example, a solid state drive (SSD) or hard disk drive (HDD)) provided in the server 20.

[0030] The contribution task DB 24 manages, as a database, contribution tasks that contribute to updating road information. Details of the contribution tasks will be described later, but a user of the vehicle 10 can earn incentives (points) by participating in a contribution task and completing the contribution task. The contribution task DB 24 also manages users or vehicles 10 that are participating in a contribution task. The map DB 23 may be configured in non-volatile storage provided in the server 20.

[0031] The data analysis device 25 analyzes whether the vehicle outside information received from the vehicle 10 is valid for use as road information. If the data analysis device 25 determines that the vehicle outside information is valid, the data analysis device 25 may reflect the contents of the vehicle outside information in the road information in the map DB 23. The data analysis device 25 may be included in the control device 21.

[0032] The electronic wallet 26 holds and manages the source of incentives (for example, points) to be awarded to users of the vehicle 10 who complete contribution tasks.

[0033] <Sequence chart> FIG. 3 is a sequence chart showing the processing of the road information collection system 1 according to the first embodiment. FIG. 4 is a diagram showing an example of a route selection screen 200 according to the first embodiment. FIG. 5 is a diagram showing an example of a required equipment screen 210 according to the first embodiment. FIG. 6 is a diagram showing an example of a contribution task in progress screen 220 according to the first embodiment. FIG. 7 is a diagram showing an example of a contribution task completion screen 230 according to the first embodiment. FIG. 8 is a diagram showing an example of a points assignment screen 240 according to the first embodiment. FIG. 9 is a diagram showing an example of a points list screen 250 according to the first embodiment. Next, an overview of the processing performed by the server 20 and the vehicle 10 will be described with reference to FIGS. 3 to 9. Note that in the following description, processing mainly performed by the vehicle 10 may be replaced with processing mainly performed by the IVI device 15 provided in the vehicle 10 or another device, and processing mainly performed by the server 20 may be replaced with processing mainly performed by the control device 21 provided in the server 20 or another device.

[0034] The server 20 lists the road information whose expiration date has passed, and registers a contribution task for collecting the road information in the contribution task DB 24 (S11). The contribution task includes at least a contribution route for updating the road information whose expiration date has passed.

[0035] The vehicle 10 generates a route search request to search for a route from the current location to the destination, and transmits the request to the server 20 (S12). The current location may be identified by the positioning sensor 12. The destination may be input by the user operating the input device 18.

[0036] The server 20 receives a route search request from the vehicle 10 and searches for a route from the current location to the destination (S13). At this time, the server 20 searches for a contribution route that can reach the destination from the current location, in addition to a general route from the current location to the destination, from the contribution task DB 24. Then, the server 20 calculates points to be awarded to the user when the contribution route is traveled (i.e., when the contribution task is completed).

[0037] The server 20 transmits the route search results including the general route, the contributing route, and the points to the vehicle 10 (S14).

[0038] Based on the route search results received from server 20, vehicle 10 displays route selection screen 200 as shown in Fig. 4 on display device 19 (S15). For example, route selection screen 200 displays, as general routes, (A) the shortest route, which is the shortest distance from the current location to the destination, (B) the fastest route, which is the shortest time it takes to get from the current location to the destination, (C) the ECO route, which is the least fuel-efficient route from the current location to the destination, and (D) the standard route, which is the standard route from the current location to the destination. In addition, the route selection screen displays (E) and (F) contribution routes that can reach the destination from the current location, the time limit for the contribution route, the number of participants in the contribution route, and the points awarded for completing the contribution route.

[0039] Here, it is assumed that the user selects a contributing route from the route selection screen 200 (S16).

[0040] In this case, vehicle 10 displays on display device 19 a required equipment screen 210 showing the equipment required to complete the selected contribution route, as shown in Fig. 5 (S17). Required equipment screen 210 displays, for example, a camera for capturing images outside the vehicle, a line for connecting to communication network 3 (e.g., a cellular communication network), winter tires in case the contribution route is covered in snow, four-wheel drive in case the roads on the contribution route are in poor condition, etc. This allows the user to know the necessary equipment before participating in the contribution task, allowing them to participate in the contribution task safely and securely.

[0041] When the user confirms and accepts the necessary equipment screen 210, the vehicle 10 transmits an application to participate in the selected contribution route to the server 20 (S18).

[0042] When the server 20 receives the application to participate in the contribution route, the server 20 accepts the participation of the user of the vehicle 10 in the contribution task including the contribution route (S19).

[0043] While the vehicle 10 is performing a contribution task, the vehicle 10 displays on the display device a contribution task in progress screen 220 as shown in Fig. 6 (S20). For example, the contribution task in progress screen 220 displays guidance (navigation) for the contribution route, the time limit and / or remaining time for the contribution task, and points to be awarded when the contribution route is completed.

[0044] When a special mission occurs while traveling along a route, the vehicle 10 and the server 20 execute special mission processing. Details of the special mission processing will be described later (see FIG. 10).

[0045] While traveling on the roads corresponding to the contribution route, the vehicle 10 collects vehicle external information via the external information acquisition device 16 and stores the information in memory. Then, when the vehicle 10 arrives at the destination, it transmits the vehicle external information to the server 20 (S21). At this time, the vehicle 10 displays a contribution task completion screen 230 shown in FIG. 7 on the display device 19. For example, the contribution task completion screen 230 displays a message that the contribution route has been traveled, the time required to travel the contribution route, the points to be awarded, and a message that the vehicle external information will be uploaded to the server 20.

[0046] The server 20 (data analysis device 25) checks the validity of the vehicle outside information received from the vehicle 10 (S22). Details of the validity check will be described later (see FIG. 17).

[0047] If the validity check is successful, the server 20 updates the road information of the contribution route in the map DB 23 based on the vehicle external information, and then transmits information including the contribution task completion and the awarded points to the vehicle 10 (S23).

[0048] When the vehicle 10 receives the information of step S23, it displays a points allocation screen 240 as shown in FIG. 8 on the display device 19 (S24). For example, the points allocation screen 240 displays, for example, a message that the contribution task has been completed and the points that have been allocated. Furthermore, the vehicle 10 may display a points list screen 250 as shown in FIG. 9. For example, the points list screen 250 displays a list of recently allocated points and the points currently held (i.e., the total points). These points are held and managed in the electronic wallet 14 of the vehicle 10.

[0049] According to the above process, the possibility that the user of the vehicle 10 will select a contribution route that can earn incentives (e.g., points) as one of the routes to reach the destination increases, and as a result, the possibility that vehicle external information for updating expired road information can be collected in a shorter period of time increases. In other words, the road information collection system 1 can more efficiently collect vehicle external information for updating expired road information.

[0050] <Special mission sequence chart> Fig. 10 is a sequence chart showing the processing of a special mission according to embodiment 1. Fig. 11 is a diagram showing an example of a special mission screen 260 according to embodiment 1. Next, the special mission processing shown in Fig. 3 will be described in detail with reference to Figs. 10 and 11.

[0051] The server 20 transmits special mission information to the vehicle 10 (S31). A special mission is a mission that the server 20 generates temporarily to collect information, such as whether road construction is ongoing at a certain location or what the weather is like at a certain location. The special mission information includes the route to the special mission location, the time limit, the points to be awarded, and the like, similar to the contribution task.

[0052] When the vehicle 10 receives the special mission information, it displays a special mission screen 260 as shown in Fig. 11 (S32). For example, the special mission screen 260 displays the details of the special mission, the route to the special mission point, the number of participants in the special mission, the time limit, the points to be awarded, etc.

[0053] Here, if the user of the vehicle 10 selects to participate in the special mission, the vehicle 10 transmits an application to participate in the special mission to the server 20 (S33).

[0054] The server 20 receives the application to participate in the special mission from the vehicle 10 and accepts the participation in the special mission (S34).

[0055] When the vehicle 10 completes the special mission, the vehicle 10 transmits the vehicle external information collected during the execution of the special mission to the server 20 (S35).

[0056] The server 20 (data analysis device 25) checks the validity of the vehicle external information received from the vehicle 10 (S36).

[0057] If the validity check of the vehicle external information is successful, the server 20 updates the road information for that point in the map DB 23 based on the vehicle external information. Then, the server 20 transmits information including the completion of the contribution mission and the awarded points to the vehicle 10 (S37).

[0058] When the vehicle 10 receives the information in step S37, it displays a points giving screen 240 similar to that shown in FIG. 8 on the display device 19 (S38).

[0059] According to the above process, the server 20 can efficiently collect information indicating the current situation of a desired location.

[0060] <Overall server processing> Fig. 12 is a flowchart showing an example of the overall processing executed by the server 20 according to embodiment 1. In the explanations of Figs. 12 to 17, the processing mainly performed by the server 20 may be interpreted as processing mainly performed by the control device 21 included in the server 20 or another device.

[0061] The server 20 executes a contributing task update process (S101). The contributing task update process will be described in detail later (see FIG. 13), but by this process, a contributing task is registered in the contributing task DB 24.

[0062] The server 20 determines whether or not a route search request has been received from the vehicle 10 (S102).

[0063] If the server 20 has not received a route search request (S102: NO), the server 20 proceeds to step S104. If the server 20 has received a route search request (S102: YES), the server 20 executes a contribution task presentation process (S103) and then proceeds to step S104. Details of the contribution task presentation process will be described later (see FIG. 14).

[0064] The server 20 determines whether or not an application to participate in the contribution task has been received from the vehicle 10 (S104).

[0065] If the server 20 has not received an application to participate in the contribution task (S104: NO), the server 20 proceeds to step S106. If the server 20 has received an application to participate in the contribution task (S104: YES), the server 20 executes a contribution task participation acceptance process (S105) and then proceeds to step S106. Details of the contribution task participation acceptance process will be described later (see FIG. 15).

[0066] The server 20 determines whether or not vehicle outside information has been received from the vehicle 10 (S106).

[0067] If the server 20 has not received the vehicle outside information (S106: NO), the server 20 proceeds to step S108. If the server 20 has received the vehicle outside information (S106: YES), the server 20 executes a validity check process (S107) and then proceeds to step S108. Details of the validity check process will be described later (see FIG. 17).

[0068] The server 20 executes a contributing task in-progress process (S108) and returns the process to step S101. Details of the contributing task in-progress process will be described later (see FIG. 16).

[0069] <Contribution task update process> 13 is a flowchart showing an example of a contributing task update process executed by the server 20 according to Embodiment 1. This process is called in step S101 of FIG.

[0070] The server 20 assigns 0 to (that is, initializes) a variable N (S201).

[0071] The server 20 adds 1 to the variable N (S202).

[0072] The server 20 determines whether or not the N-th road information exists in the map DB 23 (S203).

[0073] If the Nth road information does not exist (S203: NO), the server 20 completes this process and returns the process to the caller (S101).

[0074] If the Nth road information exists (S203: YES), the server 20 determines whether the validity period of the Nth road information has expired (exceeded) (S204).

[0075] If the validity period of the Nth road information has not expired (S204: NO), the server 20 returns the process to step S202.

[0076] If the Nth road information has expired (S204: YES), the server 20 registers the update of the Nth road information as the Nth contributing task in the contributing task DB 24 (S205). The contributing task includes a contributing route that includes the road section that corresponds to the road information.

[0077] The server 20 sets a time limit for the Nth contribution task based on the distance of the contribution route for the Nth contribution task and the time required to complete the contribution route (S206). For example, the time limit is set as a predetermined multiple (e.g., 1.5 times) of the time required to complete the contribution route. The time required to complete the contribution route may be calculated using a conventional route search method.

[0078] The server 20 sets points to be awarded to the user who completes the Nth contribution task based on the difficulty, required time, and / or distance of the Nth contribution task (S207), and registers the points in the contribution task DB 24. The value of the points to be awarded may be, for example, a value that covers the electricity cost or fuel consumption required to complete the contribution task. Then, the server 20 returns the process to step S202.

[0079] Through the above process, the contributing task is registered in the contributing task DB 24.

[0080] <Contribution task presentation process> 14 is a flowchart showing an example of a contribution task presentation process executed by the server 20 according to Embodiment 1. This process is called in step S103 of FIG.

[0081] The server 20 identifies the current location and the destination from the route search request received from the vehicle 10 (S301).

[0082] The server 20 determines whether or not the route for the vehicle 10 has been searched or set (S302).

[0083] If the route has been searched or set (S302: YES), the server 20 determines whether or not there is a special mission between the current location and the destination (S303). If there is no special mission between the current location and the destination (S303: NO), the server 20 returns the process to the caller (S103). If there is a special mission between the current location and the destination (S303: YES), the server 20 transmits special mission information to the vehicle 10 (S304) and returns the process to the caller (S103).

[0084] If the route has not been searched or set (S302: NO), the server 20 searches for a general route from the current location to the destination (S305).

[0085] The server 20 refers to the contribution task DB 24 and determines whether or not a contribution route exists between the current location and the destination (S306).

[0086] If there is no contributing route between the current location and the destination (S306: NO), the server 20 transmits the route search results including the searched general route to the vehicle 10 (S307) and returns the process to the caller (S103).

[0087] If a contributing route exists between the current location and the destination (S306: YES), the server 20 transmits the route search results to the vehicle 10 (S308), including the general route that was searched, the contributing route that exists between the current location and the destination, and the points to be awarded for completing the contributing route, and returns the processing to the caller (S103).

[0088] Through the above processing, the server 20 can transmit the contribution route along with the general route to the vehicle 10. Note that the general route may be read as the first route, and the contribution route as the second route. Furthermore, the distance (first distance) of the general route (first route) may be shorter than the distance (second distance) of the contribution route (second route). In other words, the distance (second distance) of the contribution route (second route) may be longer than the distance (first distance) of the general route (first route). This is because points can be awarded even if the distance of the contribution route is longer than the distance of the general route, which motivates the user to select the contribution route.

[0089] <Contribution task acceptance process> 15 is a flowchart showing an example of a contribution task reception process executed by the server 20 according to Embodiment 1. This process is called in step S105 of FIG.

[0090] The server 20 receives information indicating a participant ID (e.g., participant ID "ABC") and an application to participate in the Xth contribution task from the vehicle 10 (S401). The participant ID is an ID for identifying a user (or vehicle) participating in the contribution task.

[0091] The server 20 manages the Xth contribution task by linking the participant ID "ABC" to the Xth contribution task (S402). In this way, the server 20 manages that the user with the participant ID "ABC" is participating in the Xth contribution task.

[0092] The server 20 sets a time limit for the Xth contribution task for the participant ID "ABC" associated with the Xth contribution task, and starts counting down the time limit (S403). In other words, the server 20 manages the time limit for each participant in the Xth contribution task.

[0093] The server 20 transmits information indicating acceptance of participation in the contribution task to the vehicle 10 of the user with the participant ID "ABC" (S404), and returns the process to the caller (S105).

[0094] 15 may be performed for each user participating in the Xth contribution task, whereby the server 20 manages each user participating in the Xth contribution task and the time limit.

[0095] <Processing during contribution task> 16 is a flowchart showing an example of a contributing task in-progress process executed by the server 20 according to Embodiment 1. This process is called in step S108 of FIG.

[0096] The server 20 assigns 0 to (that is, initializes) the variable T (S501).

[0097] The server 20 adds 1 to the variable T (S502).

[0098] The server 20 determines whether or not there is a participant in the Tth contribution task (S503).

[0099] If there is a participant in the Tth contribution task (S503: YES), the server 20 notifies the vehicle 10 of the user of the participant ID whose time limit countdown has reached 0 that the time limit for the contribution task has expired (time-up), and disassociates the participant ID from the Tth contribution task (S504). As a result, the server 20 deletes the user who participated in the contribution task and whose time limit has expired from the contribution task. The server 20 then proceeds to step S505.

[0100] If there is no participant in the Tth contribution task (S503: NO), the server 20 advances the process to step S505.

[0101] The server 20 determines whether or not all the contribution tasks have been confirmed (S505).

[0102] If there are any contribution tasks that have not yet been confirmed (S505: NO), the server 20 returns the process to step S502. If all contribution tasks have been confirmed (S505: YES), the server 20 returns the process to the caller (S108).

[0103] <Validity check process> 17 is a flowchart showing an example of the validity check process executed by the server 20 according to Embodiment 1. This process is called in step S107 of FIG.

[0104] The server 20 analyzes the vehicle external information received from the vehicle 10 and determines whether the contributing route has been completed within the time limit (S601).

[0105] If the contribution route is not completed within the time limit (S601: NO), the server 20 sends information indicating the failure of the contribution task and the reason for the failure to the vehicle 10 with participant ID "ABC" (S620), and returns the process to the caller (S107).

[0106] If the contributing route has been traveled within the time limit (S601: YES), the server 20 determines whether the travel route indicated by the vehicle external information includes the start point, end point, and all sections of the contributing route (S602).

[0107] If the starting point, the ending point and at least a part of the section of the contributing route are not included in the travel route indicated by the vehicle external information (S602: NO), the server 20 proceeds to the process of step S620 described above.

[0108] If the driving route indicated by the vehicle external information includes all of the start point, end point, and sections of the contributing route (S602: YES), the server 20 determines whether the vehicle external information includes all of the predetermined sensor values ​​(S603).

[0109] If at least some of the predetermined sensor values ​​are not included in the vehicle external information (S603: NO), the server 20 proceeds to the process of step S620.

[0110] If all the predetermined sensor values ​​are included in the vehicle outside information (S603: YES), the server 20 determines whether the vehicle outside image included in the vehicle outside information is clear (S604).

[0111] If the vehicle exterior image included in the vehicle exterior information is unclear (S604: NO), the server 20 proceeds to the process of step S620 described above.

[0112] If the vehicle exterior image included in the vehicle exterior information is clear (S604: YES), or if the vehicle exterior image is not required, the server 20 notifies the vehicle 10 of the user with participant ID "ABC" that the contribution task has been completed and awards points (S605).

[0113] The server 20 determines whether there are other participants in the Xth contribution task (S606).

[0114] If there are other participants in the Xth contribution task (S606: YES), the server 20 notifies all other participants of the completion of the Xth contribution task (S607), and proceeds to step S608. As shown in steps S605 to S607, the server 20 may award an incentive (points) to the user (vehicle 10) who first completed the contribution route, but may not award incentives (points) to users (vehicles 10) who complete the contribution route second or later.

[0115] If there is no other participant in the Xth contribution task (S606: NO), the server 20 proceeds to step S608.

[0116] The server 20 deletes the Xth contribution task (S608).

[0117] The server 20 reflects the sensor values ​​and the outside vehicle image obtained from the vehicle external information in the Y-th road information in the map DB 23 (S609). Here, the Y-th road information refers to the road information collected by the X-th contributing task.

[0118] The server 20 sets a new expiration date for the Y-th road information in the map DB 23 (S610) and returns the process to the caller (S107). The server 20 may set an expiration date (for example, one week or one month) according to the content of the road information.

[0119] <Overall vehicle processing> Fig. 18 is a flowchart showing an example of the overall processing executed by the vehicle according to embodiment 1. Fig. 19 is a diagram showing an example of a contribution task end screen according to embodiment 1. In the explanations of Figs. 18 to 22, the processing mainly performed by the vehicle 10 may be interpreted as processing mainly performed by the IVI device 15 provided in the vehicle 10 or another device.

[0120] The vehicle 10 determines whether or not the user has input a route search to the destination through the input device 18 (S701).

[0121] If the user has not input a route search to the destination (S701: NO), the vehicle 10 proceeds to step S706.

[0122] If the user inputs a route search to the destination (S701: YES), the vehicle 10 executes a route search request process (S702). The route search request process will be described in detail later (see FIG. 20), but by this process, the vehicle 10 displays the route selection screen 200 shown in FIG. 4 and obtains the route selected by the user.

[0123] The vehicle 10 determines whether the user has selected a contributing route from the route candidates (S703).

[0124] If the user selects a contribution route (S703: YES), the vehicle 10 executes a contribution task participation process (S704) and proceeds to step S705. The contribution task participation process will be described in detail later (see FIG. 21).

[0125] If the user does not select a contributing route (for example, if the user selects a general route) (S703: NO), the vehicle 10 proceeds to step S705.

[0126] The vehicle 10 sets the route selected by the user and starts guidance (navigation) (S705). If the user selects a contributing route (i.e., if step S704 is executed), the vehicle 10 may set the contributing route.

[0127] The vehicle 10 periodically inquires of the server 20 whether or not there is a special mission on the route, and determines whether or not there is a special mission on the route (S706).

[0128] If there is no special mission on the route (S706: NO), the vehicle 10 proceeds to step S710.

[0129] If there is a special mission on the route (S706: YES), the vehicle 10 displays a special mission screen 260 on the display device 19 as shown in FIG. 11 (S707).

[0130] The vehicle 10 determines whether the user has selected to participate in the special mission (S708).

[0131] If the user selects to participate in the special mission (S708: YES), the vehicle 10 executes a special mission participation process (S709) and proceeds to step S710. Details of the special mission participation process will be described later (see FIG. 22).

[0132] If the user does not select to participate in the special mission (S708: NO), the vehicle 10 proceeds to step S710.

[0133] The vehicle 10 determines whether or not it has arrived at the end point of the contribution task (S710). Note that the end point of the contribution task may be the same as the destination point, or may be different from the destination point.

[0134] If the vehicle 10 has arrived at the end point of the contribution task (S710: YES), the vehicle 10 displays the arrival at the end point and transmits vehicle external information (including the participant ID, driving route, outside vehicle image, sensor values, etc.) to the server 20 (S711). Then, the vehicle 10 proceeds to step S712.

[0135] If the vehicle 10 has not arrived at the end point of the contribution task (S710: NO), the vehicle 10 proceeds to step S712.

[0136] The vehicle 10 determines whether or not a notification of the end of the contribution task has been received from the server 20 (S712).

[0137] When a notification of the completion of the contribution task is received from the server 20 (S712: YES), the vehicle 10 displays a contribution task completion screen for the vehicle 10 in participation on the display device (S713) and proceeds to step S714. For example, the contribution task ends when the vehicle 10 completes the contribution task, when the time limit expires, or when another participant completes the contribution task. For example, when another participant completes the contribution task, the vehicle 10 displays a contribution task completion screen 270 as shown in FIG. 19. In this case, the contribution task completion screen 270 may display a message indicating that the other participant has completed the contribution task, and therefore the contribution task has ended and guidance will be switched to a general route. In other words, when the other participant completes the contribution task, the vehicle 10 participating in the contribution task may switch guidance from the contribution route to a general route.

[0138] If the vehicle 10 has not received a notification of the end of the contributing task from the server 20 (S712: NO), the vehicle 10 proceeds to step S714.

[0139] The vehicle 10 determines whether or not it has arrived at the navigation destination (S714).

[0140] If the vehicle 10 has not arrived at the navigation destination (S714: NO), the vehicle 10 returns the process to step S706.

[0141] If the vehicle 10 has arrived at the navigation destination (S714: YES), the vehicle 10 ends the navigation (S715) and returns the process to step S701.

[0142] <Route search request processing> 20 is a flowchart showing an example of a route search request process executed by the vehicle according to Embodiment 1. This process is called in step S702 of FIG.

[0143] The vehicle 10 transmits a route search request including the current location and the destination to the server (S801).

[0144] The vehicle 10 waits until it receives the route search result from the server 20 (S802: NO), and if it receives the route search result from the server 20 (S802: YES), it proceeds to step S803. The route search result includes, for example, a general route (e.g., shortest route, fastest route, ECO route, standard route), as well as an Xth contribution route, a Zth contribution route, awarded points, etc.

[0145] Based on the received route search results, the vehicle 10 displays the route selection screen 200 as shown in FIG. 2 on the display device 19 (S803), and returns the process to the caller (S702).

[0146] <Contribution task participation process> Fig. 21 is a flowchart showing an example of a contribution task participation process executed by the vehicle according to embodiment 1. This process is called in step S704 in Fig. 18. The following is an example of the process when the user selects the Xth contribution route.

[0147] The vehicle 10 displays the necessary equipment screen 210 as shown in FIG. 5 on the display device 19 (S901).

[0148] The vehicle 10 transmits information including the participant ID "ABC" and an application to participate in the Xth contribution task to the server (S902).

[0149] The vehicle 10 waits until it receives acceptance of participation in the Xth contribution task from the server 20 (S903: NO), and when it receives acceptance of participation in the Xth contribution task from the server 20 (S903: YES), it proceeds to step S904.

[0150] The vehicle 10 displays a contribution task in progress screen 220 as shown in FIG. 6 on the display device 19 (S903), and returns the process to the caller (S704).

[0151] <Special Mission Participation Processing> 22 is a flowchart showing an example of the special mission participation process executed by the vehicle 10 according to embodiment 1. This process is called in step S709 in FIG.

[0152] The vehicle 10 transmits information including the participant ID "ABC" and an application to participate in the special mission to the server (S1001).

[0153] The vehicle 10 waits until it receives acceptance of participation in the special mission from the server 20 (S1002: NO), and when it receives acceptance of participation in the special mission from the server 20 (S1002: YES), it proceeds to step S1003.

[0154] The vehicle 10 displays the special mission screen 260 as shown in FIG. 11 on the display device 19 (S1003), and returns the process to the caller (S709).

[0155] (Summary of the first embodiment) The above description of the first embodiment discloses the following techniques.

[0156] <Technology 1> In the first embodiment, a control method for a display device (19), an input device (18), an external information acquisition device (16), and a transmission device (e.g., a communication device 11) mounted on a vehicle (10) displays a first route (e.g., a general route) to a predetermined destination and a second route (e.g., a contributing route) different from the first route on the display device, and the second route displayed on the display device also indicates that information outside the vehicle is collected and transmitted to the outside while traveling on the second route, and when the second route is selected by operating the input device, the display device displays a guidance display guiding the vehicle along the second route, the external information acquisition device acquires vehicle external information on the second route, and the transmission device transmits the vehicle external information to the outside. Thus, when the second route is selected, the vehicle can acquire and transmit vehicle external information on the second route while traveling along the second route. Thus, for example, the server (20) can receive external vehicle information on the second route from the vehicle and update road information on the roads corresponding to the second route.

[0157] <Technology 2> In the control method described in Technique 1, the first distance of the first route is shorter than the second distance of the second route. In this way, the first distance of the first route may be shorter than the second distance of the second route, or in other words, the second distance of the second route may be longer than the first distance of the first route.

[0158] <Technology 3> In the control method described in Technology 1 or 2, the second route displayed on the display device also displays an incentive for completing the second route, and after the second route is selected by operating the input device, the incentive is granted when the vehicle completes the second route. This increases the likelihood that the vehicle user will select the second route and complete the second route in order to receive the incentive, thereby increasing the likelihood that the server will be able to collect external vehicle information on the second route, and thus enabling the server to efficiently update road information corresponding to the second route.

[0159] <Technology 4> In the control method according to any one of the first to third aspects, the second route displayed on the display device also displays a time limit for completing the second route. This allows the user of the vehicle to check the time limit for completing the second route.

[0160] <Technology 5> In the control method described in any one of Techniques 1 to 4, if the second route is selected by operating the input device and the vehicle completes the second route within the time limit, the incentive is granted, and if the second route is selected by operating the input device and the vehicle does not complete the second route within the time limit, the incentive is not granted. This encourages vehicle users to complete the second route within the time limit in order to receive the incentive, which increases the likelihood that the server can collect external vehicle information on the second route in a short period of time, thereby enabling the server to efficiently update road information corresponding to the second route.

[0161] <Technology 6> In the control method according to any one of the first to fifth aspects, the second route displayed on the display device also displays the number of other vehicles traveling on the second route. This allows the user of the vehicle to see the number of other vehicles participating in completing the second route.

[0162] <Technology 7> In the control method described in any one of techniques 1 to 6, the incentive is granted when the second route is completed first, and the incentive is not granted when the second route is completed second or later. This encourages vehicle users to complete the second route first in order to receive an incentive, which increases the likelihood that the server can collect external vehicle information on the second route in a short period of time, thereby enabling the server to efficiently update road information corresponding to the second route.

[0163] <Technology 8> In the control method described in any one of Techniques 1 to 7, when the second route is selected by operating the input device, the display device displays the necessary equipment required for traveling the second route, and then the display device displays the guidance display that guides the user along the second route. This allows the vehicle user to check in advance the necessary equipment required to complete the second route.

[0164] <Technology 9> In the control method described in Technology 8, when the second route is selected by operating the input device, the display device displays the necessary equipment required for traveling the second route, and when the input device is subsequently operated to input that the necessary equipment has been confirmed, the display device displays the guidance display that guides the user along the second route. This allows the vehicle user to check in advance what equipment is necessary to travel the second route, and participate in traveling the second route safely and securely.

[0165] <Technology 10> In the control method described in any one of Techniques 1 to 9, the external information acquisition device includes at least one of a camera mounted on the vehicle and acquiring external images, a sonar mounted on the vehicle and detecting external obstacles using sound waves, a radar mounted on the vehicle and detecting external obstacles using electromagnetic waves, a speedometer mounted on the vehicle and detecting the speed of the vehicle, an accelerometer mounted on the vehicle and detecting the acceleration of the vehicle, or an angular accelerometer mounted on the vehicle and detecting the angular acceleration of the vehicle. This allows the vehicle to transmit at least one of an external image, an external obstacle, the speed of the vehicle, the acceleration of the vehicle, and the angular acceleration of the vehicle to the outside as vehicle external information.

[0166] <Technology 11> A vehicle (10) equipped with a display device (19), an input device (18), an external information acquisition device (16), and a transmission device (e.g., a communication device 11) displays on the display device a first route (e.g., a general route) to a predetermined destination and a second route (e.g., a contributing route) different from the first route, and the second route displayed on the display device also indicates that information outside the vehicle is collected and transmitted to the outside while traveling along the second route, and when the second route is selected by operating the input device, the display device displays a guidance display guiding the vehicle along the second route, the external information acquisition device acquires vehicle external information on the second route, and the transmission device transmits the vehicle external information to the outside. Thus, when the second route is selected, the vehicle can acquire and transmit vehicle external information on the second route while traveling along the second route. Thus, for example, the server (20) can receive external vehicle information on the second route from the vehicle and update road information on the roads corresponding to the second route.

[0167] <Technology 12> In the vehicle described in Technology 11, a first distance of the first route is shorter than a second distance of the second route. In this way, the first distance of the first route may be shorter than the second distance of the second route, or in other words, the second distance of the second route may be longer than the first distance of the first route.

[0168] <Technology 13> In the control method described in Technology 11 or 12, the second route displayed on the display device also displays an incentive for completing the second route, and after the second route is selected by operating the input device, the incentive is granted when the vehicle completes the second route. This increases the likelihood that the vehicle user will select the second route and complete the second route in order to receive the incentive, thereby increasing the likelihood that the server will be able to collect external vehicle information on the second route, and thus enabling the server to efficiently update road information corresponding to the second route.

[0169] <Technology 14> In the vehicle according to any one of techniques 11 to 13, the second route displayed on the display device also displays a time limit for completing the second route. This allows the user of the vehicle to check the time limit for completing the second route.

[0170] <Technology 15> In the vehicle described in any one of techniques 11 to 14, if the second route is selected by operating the input device and the vehicle completes the second route within the time limit, the incentive is granted, and if the second route is selected by operating the input device and the vehicle does not complete the second route within the time limit, the incentive is not granted. This encourages vehicle users to complete the second route within the time limit in order to receive the incentive, which increases the likelihood that the server can collect external vehicle information on the second route in a short period of time, thereby enabling the server to efficiently update road information corresponding to the second route.

[0171] <Technology 16> In the vehicle according to any one of techniques 11 to 15, the second route displayed on the display device also displays the number of other vehicles traveling on the second route. This allows the user of the vehicle to see the number of other vehicles participating in completing the second route.

[0172] <Technology 17> In a vehicle described in any one of techniques 11 to 16, if the second route is completed first, the incentive is granted, and if the second route is completed second or later, the incentive is not granted. This encourages vehicle users to complete the second route first in order to receive an incentive, which increases the likelihood that the server can collect external vehicle information on the second route in a short period of time, thereby enabling the server to efficiently update road information corresponding to the second route.

[0173] <Technology 18> In the vehicle described in any one of Techniques 11 to 17, when the second route is selected by operating the input device, the display device displays the necessary equipment required for traveling the second route, and then the display device displays the guidance display guiding the user along the second route. This allows the vehicle user to check in advance the necessary equipment required to complete the second route.

[0174] <Technology 19> In the vehicle described in Technology 18, when the second route is selected by operating the input device, the display device displays the necessary equipment required for traveling the second route, and when the input device is subsequently operated to input that the necessary equipment has been confirmed, the display device displays the guidance display guiding the driver along the second route. This allows the vehicle user to check in advance what equipment is necessary to travel the second route, and participate in traveling the second route safely and securely.

[0175] <Technology 20> In the vehicle described in any one of techniques 11 to 19, the external information acquisition device includes at least one of a camera mounted on the vehicle and acquiring external images, a sonar mounted on the vehicle and detecting external obstacles using sound waves, a radar mounted on the vehicle and detecting external obstacles using electromagnetic waves, a speedometer mounted on the vehicle and detecting the speed of the vehicle, an accelerometer mounted on the vehicle and detecting the acceleration of the vehicle, or an angular accelerometer mounted on the vehicle and detecting the angular acceleration of the vehicle. This allows the vehicle to transmit at least one of an external image, an external obstacle, the speed of the vehicle, the acceleration of the vehicle, and the angular acceleration of the vehicle to the outside as vehicle external information.
