| 摘 要： | 提出了ACC车辆与前车之间的速度一位移关系以及分别以车距控制和相对车速控制为目标的2种LQR模型，并根据两车的速度一位移关系的不同实现2种模型之间的转换，以生成符合驾驶员操作行为的ACC车辆控制目标，建立了实现控制目标的车速控制模型。仿真计算表明控制策略满足乘坐舒适性和保持安全车距的要求。

| Abstract: | The speed-distance relationship between the adaptive cruise control(ACC) vehicle and its proceeding vehicle are described by relative speed of two vehicles and the discrepancy between real distance of two vehicles and the vehicle safe distance.Two LQR models,aiming at headway distance control and relative speed control respectively,are proposed to deal with different speed-distance relationships of two vehicles.Appropriate transitions between two LQR models are needed to ensure the response of ACC vehicle conforming to driver's intention. The simulation results show that the control strategy meets the requirements of ride comfort and safe distance of vehicles. |
