Advanced Integrated Control Strategy Based on SBW and 4WS

摘要

This paper proposes a chassis integrated control system theoretically utilizing SBW system by using 4WS method to improve vehicle handling and stability. With the application of integrated SBW and 4WS strategy, this paper investigates the effectiveness of the proposed control system in enhancing vehicle handling and stability. Based on the 7 DOF vehicle dynamic models, the paper have proposed integrated control strategy for SBW and 4 WS including forward and feedback control methods in the four wheels (4WS). Two control methods are compared by simulation results and driver simulator test results. The simulation results indicated that 4WS for SBW can effectively improve the vehicle handling.
