First, the user of each in-vehicle system 110 acquires desired route information selected from the plurality of candidate routes described above from all the in-vehicle systems 110 via the route information communication unit 107 (steps 601 and 602). .
In step 601 and step 602, if desired route information selected from the plurality of candidate routes described above cannot be acquired from all the in-vehicle systems 110, the process is terminated.
When the desired route information selected from the plurality of candidate routes described above is acquired from all the in-vehicle systems 110 in step 601 and step 602, main route information is determined from the desired route information acquired from all the in-vehicle systems (step 603), the determined route information is registered in the route information management table 102, and the main route information is notified to all in-vehicle systems 110 in the group via the route information communication unit 107 (step 604). All in-vehicle systems 110 in the group store the received main route information in the route information management table 117.
In step 603, main route information is determined by majority vote. That is, the most desired route information among the desired route information acquired from all the in-vehicle systems 110 is determined as main route information. In addition, when there are a plurality of pieces of desired information among the desired route information acquired from all the in-vehicle systems 110, the information management server 100 determines uniquely.

Next, using FIG. 7 to FIG. 8, the vehicle management system 110 notifies the information management server 100 that the vehicle equipped with the vehicle mounted system has deviated from the main route, and then it is transmitted to all the vehicle mounted systems 110 in the group. A method for distributing deviation status information will be described.
FIG. 7 is a flowchart showing the processing procedure of the return route calculation process when the vehicle equipped with the own vehicle system deviates from the main route in the vehicle system 110 according to the embodiment of the present invention.
First, based on the main route information stored in the route information management table 117, when the navigation unit 112 detects that a vehicle equipped with the own vehicle system deviates from the main route (step 701), the own vehicle system is installed. It is determined whether the vehicle to be operated is currently traveling in a group (step 702).
If the vehicle equipped with the in-vehicle system is not currently traveling in a group, the navigation unit 112 recalculates the route to the destination (step 705).
If the vehicle equipped with the in-vehicle system is currently traveling in a group, the information management server 100 is notified of deviation status information (for example, information on deviation) via the information communication unit 113 (step 703). The navigation unit 112 calculates a return route to the branch point with the main route (step 704).
Note that the processing from step 701 to step 704 is executed continuously (for example, every few minutes or every several tens of minutes) until the vehicle equipped with the in-vehicle system returns to the main route. When a vehicle deviating from the main route returns to the main route, return status information (for example, information during normal traveling) is transmitted to the information management server 100 via the information communication unit 113.

FIG. 8 is a flowchart illustrating a processing procedure of the deviation status distribution processing in the information management server 100 according to the embodiment of this invention.
First, the deviation status information from the information communication unit 113 of the in-vehicle system mounted on the vehicle deviating from the main route is acquired via the deviation status communication unit 108 (step 801).
Next, it is determined whether or not the vehicle deviating from the main route continues to deviate from the main route (step 802). If the vehicle deviating from the main route continues to deviate from the main route, The process ends.
That is, in step 802, it is determined whether the deviation status information from the in-vehicle system mounted on the vehicle deviating from the main route is the first deviation status information or the second and subsequent deviation status information, and the determination result in step 802 However, in the case of deviation status information for the second and subsequent times, the process is terminated.
If the determination result in step 802 is the first deviation status information, the deviation status information is notified to all in-vehicle systems of the group to which the in-vehicle system mounted on the vehicle deviating from the main route belongs (step 803). .

In step 802, the vehicle deviating from the main route still deviates from the main route until the return status information is received from the information communication unit 113 of the in-vehicle system mounted on the vehicle deviating from the main route. Judge that
Further, when a vehicle deviating from the main route returns to the main route, that is, the return status information from the information communication unit 113 of the in-vehicle system mounted on the vehicle deviating from the main route is obtained via the deviation status communication unit 108. When received, the return status information is notified to all in-vehicle systems of the group to which the in-vehicle system mounted on the vehicle deviating from the main route belongs.
As described above, according to the present embodiment, not only can a plurality of vehicles travel on a common route, but also the determination of routes from vehicles other than the leader, which is a problem of the prior art, The deviation status can be distributed to vehicles other than the leader. In addition, since there is no need for the leader, any vehicle deviating from the route can return to the route without affecting the routes of other vehicles.
