An overrunable test vehicle including an electronically-controlled anti-slip braking system for reducing wheel slip during rapid deceleration comprising: a chassis, at least one electric motor connected to a first axle, a hydraulic braking system connected with the chassis and at least a second axle, a rotational speed sensor for determining a rotational speed of a connected axle, a ground speed sensor, and a controller connected with the electric motor, the hydraulic braking system, the rotational speed sensor, and the ground speed sensor.

The first and second stopping forces combined are less than the slip threshold of the wheels such that the chassis rapidly decelerates free of a wheel slip condition.

A braking torque sensor of a brake is provided, the braking torque sensor includes: a long circular shaft hole arranged on a brake arm of the brake; a connecting plate configured to detect a braking displacement which is generated by the hinge shaft of the brake element in a long circular shaft hole and varies with the magnitude of the friction force when the braking action is performed by the brake, and convert the detected displacement into a plate deformation of the connecting plate; and a tension sensor configured to convert the plate deformation generated due to the braking action on the connecting plate into force information, and transmit the force information outwards in a form of electrical signal or digital signal. The detection result of the braking torque sensor is consistent with the actual result, so that an abnormal condition of the brake can be detected in time.
