Automobile steering alignment test system

The invention discloses an automobile steering alignment test system which comprises a steering wheel, an EPS assembly, a torque sensor, an EPS controller, a load servo motor, an upper computer and apower supply. The steering wheel is connected with the EPS assembly; the EPS assembly is connected with the load servo motor; the load servo motor is used for simulating the acting force of a steeringtie rod during automobile steering; the EPS controller is electrically connected with the EPS assembly and the power supply respectively; the upper computer is electrically connected with the EPS controller, the torque sensor and the load servo motor; the power supply is further electrically connected with the EPS controller and the load servo motor and supplies power to the EPS controller and the load servo motor; and the torque sensor is used for detecting the steering torque actually generated by the load servo motor. The test cost can be reduced, and the test period can be shortened. 本发明公开了一种汽车转向回正测试系统，包括转向盘、EPS总成
