The present paper deals with improvements in vehicle performance and efficiency using of electric driven (semi-)trailers towed by a tractor. The special focus of this paper is the possible improvement of the overall vehicle performance by adding a precise controllable electric drive in the trailer. Achievable efficiency gains or range extension for BEV trucks are discussed in other publications. Here, a description of various functions is given which improve traction and acceleration behavior, vehicle stability & safety and comfort in special driving situations. The basic idea behind the presented concept is the integration of the trailer eDrive control into the brake- and stability systems of both, truck and trailer, with the possibility to ensure safe and efficient torque distribution by incorporation of all relevant systems in truck and trailer. The concept makes use of the standardized (and in future) adapted ISO-11992-2 truck-trailer communication link as well as ZF’s detailed knowledge and capabilities in the field of electric drivetrains and vehicle control.
