Title: METHOD AND SYSTEM FOR A COMMON DRIVING STRATEGY FOR VEHICLE PLATOONS
Abstract:
A method and a system (4) to control a vehicle platoon that comprises at least one lead vehicle and one additional vehicle, each of which has a positioning unit (1) and a unit (2) for wireless communication. The system (4) comprises: - a driving profile unit (6), configured to determine a driving profile for at least one vehicle fk in the vehicle platoon along a road horizon, wherein the driving profile contains target values b for the vehicle fk at positions along the road horizon; - a change of gear profile unit (8) configured to determine a transmission gear-change profile for at least one vehicle fk in the vehicle platoon based on properties of the horizon and on properties of the particular vehicle, wherein the change of gear profile contains types of change of gear for the vehicle fk at positions along the horizon. An analysis unit (7) is configured to determine a driving strategy for the vehicles in the vehicle platoon based on at least the driving profile and the transmission gear-change profile for the vehicle fk; to generate a driving strategy signal that indicates the driving strategy, and to transmit the driving strategy signal to all vehicles in the vehicle platoon, after which the vehicles in the vehicle platoon are controlled according to the driving strategy.
