Problems solved by technology

[0002] The traditional wheel speed sensor testing station can only set the motor at a fixed speed to detect the signal output at a constant speed, and it does not have the ability to simulate and analyze the signal. It is difficult to obtain a signal close to the actual running state of the car, so it cannot Obtaining accurate standard brake signals cannot reflect the consistency between the vehicle running state reflected by the sensor electrical output signal and the actual simulated state
