Automobile ABS brake detection system

The invention discloses an automobile ABS brake detection system. An automobile is driven into a detection device, rollers make contact with wheels through a lifting device, a left brake force sensor for detecting brake force is arranged on a left rear roller, and a right brake force sensor for detecting brake force is arranged on a right rear roller; the control device controls the rotating speed of the motor through the frequency converter, enables the wheels to generate the slip rate, enables the vehicle to reach the state that an ABS plays a role, and reads a braking force curve in the process; according to the measured braking force curve and the collected linear speed curve of the surfaces of the wheels, after analysis and calculation of presence of the action of the vehicle ABS braking and braking force in the process of ABS braking and ABS braking frequency, a report sheet containing the brake curve is printed out; whether the ABS function of the vehicle is normal or not can be judged without reading
