In order to improve the vehicle handling stability, an active rear independent pulse steering system(ARIPS)which integrates independent steering and active pulse steering was proposed, and theoretical analysis and experiment study were carried out. The simulation dynamics model equipped with ARIPS system was established to analyze the effects of installation and operation of pulse actuator on the suspension performance. The optimal pulse parameters were determined according to the simulation analysis and frequency analysis method. A control structure and algorithm were designed and a full vehicle model equipped with the steering actuator was built in Carsim and co-simulated with Simulink to verify the proposed system. A hydraulic steering system was designed and assembled for a Lexus to carry out road experiments to assess the applicability of the ARIPS system. Simulation and test results obtained have shown that the proposed system has better performance in terms of improving vehicle handling stability compared with ARS and ARPS system. Meanwhile, the proposed system is economical and feasible,providing a new research space and experimental basis to improve the performance of 4WS system.
