Adaptive Launching Control Strategy of In-Wheel Motor Driven Vehicle

To further improve the safety and driving comfort of 4×2 in-wheel motor driven vehicle during launching process, this paper proposes an adaptive launching control strategy. It designs Fuzzy-PI controller and torque distribution parts to calculate motor torque by the real-time feedback information of vehicle speed, which realizes good performance of tracing desired speed. Meanwhile, a reasonable launching time and transition procedure of desired speed are set to avoid motor torque over-controlled and the driver's subjective feeling becoming worse. The time-varying proportional coefficient promotes the robustness of system. The Simulink/Carsim co-simulation platform is built to verify the proposed control method showing the effectiveness and feasibility of the method.
