四轮驱动汽车电动助力转向控制研究

Study on Electric Power Steering Control of Four Wheel Drive Vehicle

为了研究四轮驱动汽车的电动助力转向控制,建立电动助力转向系统动力学模型,提出基于模糊PID控制的电动助力转向控制策略。借助离线仿真的技术,对控制策略的有效性加以论证,得出四轮驱动汽车电动助力转向控制的最佳系统功能提升方案。

In order to study the electric power steering control of four-wheel drive vehicle,the dynamic model of elercitc power steering system is established and the control strategy of electric power steering based on fuzzy PID control is propose dB.y using the technology of offline simulation,the effectivenessf othe control strategy is demonstrated,and the optimal system functoin promotion scheme for electric power steering control of four-ewehl drive vehicle is obtained.
