【摘要】 本文以29自由度车辆动力学模型为平台,结合线控转向系统(Steer-by-wire,SBW)理想转向传动比,提出了两种前轮线控转向的稳定性控制方案;研究了分别采用前馈控制方式和反馈控制方式的电控四轮转向控制,并与前轮线控转向和传统四轮转向系统进行了比较,通过仿真和模拟器试验验证了电控四轮转向系统能有效提高汽车的操纵稳定性。更多还原

【Abstract】 Two control strategies for SBW including yaw rate feedback control and yaw rate & acceleration feedback control have been proposed based on the 29 DOF vehicle dynamic model and the steering ratio varied with the vehicle velocity and hand wheel angles.The forward and feedback control methods for SBW and four wheels steering(4WS) has been studied,and compared with 2WS for SBW and the classical 4WS.The results indicated that SBW and 4WS control method could improve the performance of vehicle handling and stability.更多还原
