The invention discloses a vehicle rear wheel steering control system. The vehicle rear wheel steering control system comprises a domain controller, an execution control module, a motor driving module,a permanent magnet synchronous motor, a rear wheel steering execution mechanism, a motor position detection module, a rack position detection module and a self-learning module, wherein the self-learning module collects motor position information and rack position information in real time, and establishes a corresponding relationship between the motor position information and the rack position information, so that the rear wheel steering angle information is directly corrected according to the rack position information output by the rack position detection module when the domain controller detects that the rack position detection module is normal, and when the rack position detection module is abnormal, the current rack position information determined by the self-learning module is acquired, and a rear wheel steering angle signal is corrected according to the current rack position information. According to the embodiment of the invention, the reliability and safety of vehicle operationcan be improved.

    本发明公开了一种车辆后轮转向控制系统,该车辆后轮转向控制系统包括域控制器、执行控制模块、电机驱动模块、永磁同步电机、后轮转向执行机构、电机位置检测模块和齿条位置检测模块以及自学习模块;该自学习模块实时采集电机位置信息和齿条位置信息,并建立电机位置信息和齿条位置信息的对应关系,以在域控制器检测到齿条位置检测模块正常时,直接根据齿条位置检测模块输出的齿条位置信息,校正后轮转角信息,而在齿条位置检测模块异常时,获取自学习模块确定的当前齿条位置信息,并根据该当前齿条位置信息校正后轮转角信号。本发明实施例能够提升车辆运行的可靠性和安全性。
