Distributed electric vehicles are typical over- actuated systems, therefore, the optimal torque distribution can be realized through the driving wheels. It is meaningful to extend driving range and reinforce stability of vehicles by using optimal torque allocation methods. In this paper, a quadratic programing based torque allocation strategy is proposed to minimize the drivetrain power loss and utilize...
It is necessary to detect vehicle speed to calculate the slip ratio in slip control systems. However, it is hardly to measure the vehicle speed directly for electric vehicle (EV) with in-wheel motors. So, this paper proposed a new slip ratio estimation method for EV with in-wheel motors based on Extended Kalman Filter (EKF) without detecting the vehicle speed. This method takes advantage of the features...
