Anti-lock Braking System (ABS) has widespread used depending on its mature technology and superior performance. We design a test rig which can simulate the running condition of wheels for ABS to detect the braking performance. The kinetic energy of vehicle is replaced by the kinetic energy of rotating flywheel, and the tire-road friction coefficient is replaced by magnetic powder clutch. The amplitude of exciting current to the clutch has linear relationship with the friction coefficient, so as to provide a datum for detecting the working status of ABS under various road conditions. The system can realize simulating test of single road surface, bisectional road surface and joint road surface. The validity of the road simulation method can be verified by the real-time data from the user interface.
