Acceleration‐based wheel slip control realized with decentralised electric drivetrain systems

Traction control is one of the most important functions in vehicle drivetrain systems. When a driven on low-friction road surface, loss traction force can cause wheels to spin. This reduces acceleration performance and even driver lose vehicle. The high bandwidth electric machine vehicles gives more possibilities regulate driving torque prevent wheel An acceleration-based slip designed investigated. Compared traditional slip-based control, proposed method does not depend estimation speed only relies rotational acceleration. verified using simulation an with decentralised system. drive are modelled CarMaker PLECS, respectively. results show that able from spinning when accelerated ice road. In addition, fast enough requires half second reduce normal range.
