Abstract

A platoon management control system and method for local detection and determination of a non-platooning vehicle inserted or otherwise disposed between and/or adjacent to one or more platooning vehicle(s). A platooning vehicle determines a forward physical distance between itself and a vehicle physically ahead, and compares the determined physical distance with a value of a rearward distance to the platooning vehicle received from a next ahead platooning vehicle. The vehicle physically ahead is determined to be the next ahead platooning vehicle in accordance with a correspondence between the determined physical distance and the received value of the rearward distance. Conversely, the vehicle physically ahead is determined to be a non-platooning vehicle in accordance with a mis-correspondence between the determined physical distance and the received value of the rearward distance.
