摘　　要：为了降低泊车系统对驾驶人车速控制要求,针对泊车过程中驾驶人车速控制失误致使车辆偏离泊车路径最终导致泊车失败的问题,提出了结合定点跟踪的非时间参考的路径跟踪控制策略(Non-Time Based Path Tracking combined with Point Tracking,NTBPTcwPT)。设计了定点跟踪控制律,建立了NTBPTcwPT控制模型,并进行了泊车路径跟踪仿真。结果表明:基于NTBPTcwPT的泊车控制策略降低了控制器对驾驶人速度控制的要求;NTBPTcwPT策略的位姿调整功能提高了泊车成功率;基于NTBPTcwPT策略的控制器可实现车辆规范停放。In order to reduce the parking system＇s requirements on velocity control for drivers, in view of the problem of parking failure caused by the car＇s departure from the parking path because of the driver＇s velocity control error during parking process, non time based path tracking combined with point tracking （NTBPTcwPT） control strategy was proposed. Point tracking control law was designed and NTBPTcwPT control model was built for parking path tracking simulation. The simulation results show that the parking control strategy based on NTBPTcwPT reduces the requirement on velocity control for drivers. Position adjustment function of NTBPTcwPT strategy improves NTBPTcwPT strategy can park the the success rate of parking. The controller based on car in regulation.
