Vehicle convoy control system and method
TLDR
In this article, a control system identifies vehicle systems for combining into a larger convoy, and the control system directs the identified vehicle systems to couple with each other for travel as the convoy from a first location toward a different, second location.Abstract:
A control system identifies vehicle systems for combining into a larger convoy. Each the vehicle systems is formed from at least one propulsion-generating vehicle and at least one non-propulsion-generating vehicle. The control system directs the identified vehicle systems to couple with each other for travel as the convoy from a first location toward a different, second location. The control system directs a first vehicle system in the convoy to separate from the convoy and/or a second vehicle system to join the convoy by coupling with at least one of the vehicle systems in the convoy in an intermediate location between the first and second locations. The vehicles in each of the vehicle systems in the convoy remain connected during separation of the first vehicle system from the convoy and/or during joining of the second vehicle system to the convoy.read more
