Development of a Vehicle Dynamics Control System for Four In-Wheel Motor EV

Abstract:

This paper describes the design of a vehicle dynamics control system for improving handling and stability of electric vehicle. A vehicle with this control system can facilitate good handling performance under normal operating conditions and enhance stability under critical conditions. A feedforward and a feedback controllers are employed to make the vehicle follow the reference yaw rate based on a non-linear 5DOF vehicle model under normal operating conditions. When the tire tends to reach physical limit, the reference value will be modified with lateral acceleration feedback. Finally, simulation is conducted under several standard maneuvers and the results verify the effectiveness of the proposed control system.
