The invention discloses an automatic calibration system and method for the zero angle of an electric circulating ball type steering gear box, and belongs to the technical field of pure electric bus debugging. The automatic calibration system comprises a vehicle speed acquisition module, a wheel speed acquisition module, a steering wheel torque sensor and a vehicle control unit, and the vehicle speed acquisition module is used for acquiring the running speed of a vehicle and transmitting the running speed to the vehicle control unit in real time; the steering wheel torque sensor is used for obtaining steering wheel input torque information and transmitting the obtained steering wheel input torque information to the vehicle control unit in real time. The whole vehicle controller analyzes the running speed, the wheel speed of each wheel and the input torque information of the steering wheel, calibration and updating of the middle angle of the electric recirculating ball type steering gear are achieved, the trouble of manual dynamic debugging and program brushing is avoided, timely whole vehicle steering return and automatic direction alignment are achieved, and the operation efficiency is improved. And the stability and the reliability of the whole vehicle steer-by-wire control are further improved.
