- a vehicle group can be formed using, for example, a target speed pattern or a target route, which is an action plan up to a predetermined point. It is possible to form a vehicle group so that the average required time of the vehicle is reduced, and it is possible to improve the efficiency of traffic flow and the average fuel consumption and average speed of multiple vehicle groups.
- the embodiment described above shows an example of the travel control device and the vehicle group formation system according to the present invention.
- the travel control device and the vehicle group formation system according to the present invention are not limited to the travel control device and the vehicle group formation system according to each of these embodiments, but within the scope not changing the gist described in each claim.
- the traveling control device and the vehicle group formation system according to each embodiment may be modified or applied to other devices.
- the force described in the example of determining whether to form a vehicle group by comparing two action plans up to a predetermined point to form a vehicle group is not limited to two, but the decision to form a vehicle group may be made by simultaneously comparing plans up to a predetermined point for three or more vehicles.
- the vehicle can travel according to the travel mode requested by the driver.
