Row-running control system and vehicle
First Claim
Patent Images
1. 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;
whereinthe 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 Ln, and the vehicle-to-vehicle error propagation ratio S is expressed by S=Ln+1/Ln.

Abstract
A vehicle platooning control system is a vehicle platooning control system that controls a relative relationship between vehicles so that a plurality of vehicles runs in a row. In this system, each target value of a relative relationship between vehicles continuous in the longitudinal direction of a row is determined on the basis of a relative relationship error propagation ratio which is a ratio of an error of the relative relationship propagated to the rear vehicles running in the row.
