Device and method of steering motor automatic zero calibration for unmanned engineering operation equipment

The invention discloses device and a method of a steering motor automatic zero calibration for unmanned engineering operation equipment. The device comprises a hinged angle sensor, a steering motor angle sensor, a steering motor power relay, a steering motor controller and a whole automobile controller. According to the device and the method, the offset of a zero position and the positive direction of an automobile body can be detected in real time in the driving process of the unmanned engineering operation equipment, and the zero position re-calibration is carried out; and the zero position of the steering motor is aligned with a front automobile body position and a rear automobile body position and corresponds to the front automobile body position and the rear automobile body position, so that the situation that the steering motor loses control capacity due to too large zero offset caused by leakage accumulation of a hydraulic steering system is avoided. 本发明公开了一种无人驾驶工程作业设备转向电机自动零位标定装置及方法，装置包括铰接角传感器、转向电机角度传
