Hall effect efficiency detection device and method of wheel speed sensor

The invention discloses a Hall effect efficiency detection device and method for a wheel speed sensor. The Hall effect efficiency detection device comprises a first motor, a hub gear ring, a wheel speed sensor mounting bracket, a driving assembly and a detection controller, an output shaft of the first motor is connected with the hub gear ring, and the first motor is used for driving the hub gear ring to rotate at a constant speed; the wheel speed sensor mounting bracket is used for fixing a wheel speed sensor to be detected, and the wheel speed sensor and the hub gear ring are oppositely arranged; the driving assembly is connected with the wheel speed sensor mounting bracket, and the driving assembly is used for driving the wheel speed sensor mounting bracket to move in the horizontal direction, so that the distance between the hub gear ring and the wheel speed sensor is changed; the detection controller is electrically connected with the first motor, the driving assembly and the wheel speed sensor.
