中文摘要：

本文对车辆在转向行驶过程中稳定性的控制策略进行研究.在ADAMS/Car中建立整车系统模型并加以验证.根据车辆失稳的主要原因,在MATLAB/Simulink中设计以控制各车轮制动力为目标的控制器,依据模糊控制理论建立车辆转向稳定性控制联合仿真模型,在不同路面附着系数下,分别针对双移线、正弦延迟及蛇形工况下车辆进行仿真试验,分析在有无控制下车辆横摆角速度和质心侧偏角的变化.仿真结果表明,施加控制的车辆行驶路径保持较好,横摆角速度和质心侧偏角能够得到很好的控制,车辆行驶稳定性得到保障,证实了控制策略的有效性.

英文摘要：

In this paper, the main research was about the control strategy on vehicle stability during the steering process. A vehicle system model was established in ADAMS/Car and confirmed the correctness. According to the main reason for the instability of the vehicle, a controller was designed to control the braking force of each wheel in the MATLAB/Simulink, the co-simulation model of the vehicle was established, used the fuzzy control strategy, accordingto some conditions like double lane change, the sine-delay and snake-like on different road adhesion coefficient, somevirtual testsof the vehicle modelwere proposed, to analyze the change of yaw rate and vehicle sideslip within or without control. Results showed that the vehicle could keep good agreement of traveling path if it was under the con- trol, either the yaw rate and sideslip angle. It guaranteed safety of the vehicle, and the effectiveness of the control strategy was confirmed.
