Abstract
A frontmost vehicle and a plurality of following vehicles are driven together in a line as a group. A virtual cell is set for each vehicle, allowing a predetermined distance in front of and behind the vehicle, and a virtual cell front end position of the frontmost vehicle is indicated from outside. A value obtained by adding the length of the virtual cell to the virtual cell front end position is transmitted to the following vehicle as the virtual cell front end position of the following vehicle. A relative position in the virtual cell of each vehicle is detected, and by controlling this relative position to a preset target position, the inter-vehicle distance is reduced and the generation of dilatational waves between the vehicles is prevented.
