Patent ID: 8660779

Claim:
A vehicle platooning control system that controls a relative positional relationship between vehicles so that a plurality of vehicles runs in a row, the vehicle platooning control system comprising: an electronic control unit having control logic configured to cause the electronic control unit to determine a target value of a vehicle-to-vehicle distance between vehicles continuous in the longitudinal direction of a row on the basis of a vehicle-to-vehicle error propagation ratio which is a ratio of a vehicle-to-vehicle error propagated to the rear vehicles during running in the row; wherein the vehicle-to-vehicle error indicates an error between the target vehicle-to-vehicle distance and an actual vehicle-to-vehicle distance; and the vehicle-to-vehicle error between an n-th vehicle and an n+1-th vehicle from a front side of the row is denoted by L n , and the vehicle-to-vehicle error propagation ratio S is expressed by S=L n+1 /L n .
