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 an ECU of the vehicle; the interaction between the braking curve and the ABS braking frequency can be visually displayed, and the ABS braking detection time is shortened.
Description
technical field [0001] The invention relates to a braking detection system, in particular to an automobile ABS braking detection system. Background technique [0002] The ABS (anti-lock braking system) of the car can significantly improve the active safety braking performance of the car, so that the vehicle can make the best use of the ground braking force to decelerate and stop, thereby improving the braking performance of the car, shortening the braking distance, and improving the safety of the car. driving safety. At present, for the detection and evaluation of the braking performance of vehicles equipped with ABS, the commonly used method is the road test method. However, the cost of the road test field is high, the detection time is long, the risk is high, it is easily affected by the surrounding environment, and the repeatability of the test results is poor. In addition, the detection of the reaction force drum brake test bench is also a main detection method. Howev...
