摘要
操纵稳定性控制是提高汽车安全性的重要措施。通过对理想二自由度模型的改进,建立了以横摆角速度和质心侧偏角为控制变量,离散PID控制的稳定性控制方法,并制定了轮胎制动力分配策略。基于CarSim和LabVIEW搭建了人在环路的仿真试验系统,进行紧急双移线试验、蛇行试验等"人-车-路"仿真试验,验证了稳定性控制策略的有效性。所搭建的仿真系统可扩展性强,有助于快速开发车辆稳定性控制系统。
Vehicle stability control is an important method to improve the safety performance of vehicles. By selecting the yaw rate and side slip angle as control variables, through the improvement of the two degree of freedom model, a stability control method was built by using a discrete PID controller and a braking force distribution strategy was developed. The driver-vehicle-road closed-loop system for the virtual stability test was built with CarSim and LabVIEW. Through the double lane change test and pylon course slalom test, the effiectiveness of the stability control strategy and the scalability of the virtual test system were both proved, which are helpful for rapid development of vehicle stability control systems.
