摘　　要：为了提高传统乘用车的安全性能,对电子稳定性控制系统的控制方法和策略进行了研究。首先研究了直接横摆力矩控制介入时机以及发动机扭矩调节控制介入时机等问题,分别采用β-相平面法和纵向速度门限值法来判断;然后设计了基于滑模控制算法的直接横摆力矩控制算法,其目标值计算依靠线性二自由度模型;发动机扭矩调节则利用模糊算法计算得到,输入值主要是车辆状态参数和驾驶员对方向盘的输入;再采用MATLAB/Simulink、AMESim、Carsim软件联仿的方式进行正弦迟滞工况仿真和方向盘增幅工况仿真,仿真结果表明配合控制算法的有效性;最后进行夏季实车实验,依据高附双移线工况实验数据,表明设计的方法符合ISO-3888-1标准。In order to improve the safety performance of traditional passenger cars,the control methods and strategies of electronic stability control system were studied.The intervening time of direct yaw moment control and engine torque regulation control were stualied,and the direct yaw moment control algorithm based on sliding mode control algorithm and the engine torque regulation control method based on variable parameter PID-fuzzy algorithm were designed.Simulink,AMESim and Carsim software were used to simulate the sinusoidal hysteresis and steering wheel increment conditions.Simulation results show that the proposed method is effective.Finally,through the summer vehicle experiment,the high-attachment double-line-shifting condition experiment is carried out.Experimental data show that the method designed meets the ISO-3888-1 standard.
