The invention provides a steering gear autonomous zero calibration control system and a steering gear autonomous zero calibration control method. The steering gear autonomous zero calibration control system comprises a data acquisition module used for acquiring required bus message information; the vehicle mass calculation module is used for calculating the vehicle mass; the steering wheel angle calculation module is used for calculating a corresponding steering wheel sensor angle value; the tire pressure calculation module is used for receiving the tire pressure measured by the tire pressure sensor; the straight-line driving judgment module is used for judging whether the vehicle is in a straight-line driving state or not according to the wheel rotation angle obtained by the wheel rotation angle sensor in the steering controller; the zero angle control module is used for vehicle zero angle control calibration; and the data storage module is used for storing the data in the corresponding NVRAM after the vehicle learns new zero angle data. The problem that a steering wheel is not correct due to the fact that the electric power steering zero angle of the vehicle deviates from the zero position due to changes of the mass and the tire pressure of the vehicle is solved.

    本发明提供了一种转向器自主零位标定控制系统及方法,系统包括:数据采集模块:用于获取所需的总线报文信息;车辆质量计算模块:用于计算车辆质量;方向盘角度计算模块:用于计算相应的方向盘传感器角度值;胎压计算模块:接收胎压传感器测出的轮胎胎压;直线行驶判断模块:用于在转向控制器中,根据车轮旋转角度传感器获取的车轮旋转角度判断车辆是否处于直线行驶状态;零角度控制模块:用于车辆零角度控制标定;数据存储模块:用于当车辆学习到新的零角度数据后,将数据保存到相应的NVRAM中。本发明解决了当车辆因质量、胎压发生变化而造成车辆电动助力转向零角度发生偏离零位、造成方向盘不正的问题。
