Abstract
Disclosed is a vehicle group control method which controls traveling of a vehicle group having n vehicles (where n=2, 3, . . . ). In extending the inter-vehicle distance between a (j−1)th vehicle from the front and a j-th vehicle (where j=2, 3, . . . , n) within the vehicle group, the relative speed of the j-th vehicle with respect to the (j−1)th vehicle during the changing of the inter-vehicle distance is changed as indicated by a graph with a minimum value on a time axis.
