Abstract
Systems and methods for coordinating and controlling vehicles, for example heavy trucks, to follow closely behind each other, or linking to form a platoon. In one aspect, on-board controllers in each vehicle interact with vehicular sensors to monitor and control, for example, relative distance, relative acceleration or deceleration, and speed. In some aspects, a lead vehicle can wirelessly transmit information from various electronic control units (ECUs) to ECUs in a rear vehicle. A rear vehicle can then apply transformations to the information to account for a desired following distance and a time offset. ECUs onboard the rear vehicle may then be controlled based on the ECUs of the lead vehicle, the desired following distance, and the time offset.
