The present invention belongs to the technical field of test, and discloses an air pressure ABS controller detection method and device. The device comprises a waveform generator, a PC, a CAN communication module, an air pressure ABS controller, an air pressure ABS valve, an indicating lamp and a pneumatic clamp. The method comprises the steps of: sending simulation wheel speed signals through thewaveform generator to the air pressure ABS controller, sending feedback wheel speed signals to the PC through the CAN communication module by the air pressure ABS controller, performing comparison ofthe feedback wheel speed signals with the simulation wheel speed signals by the PC, and determining whether the functions of the air pressure ABS controller are qualified or not in an error range according to a comparison result. The air pressure ABS controller detection method and device can be used for offline detection of ABS controller products.
Description
technical field [0001] The invention relates to the technical field of testing, in particular to a method and device for detecting an air pressure ABS controller. Background technique [0002] In order to improve the driving safety of automobiles, commercial vehicles such as trucks and passenger cars are generally equipped with pneumatic ABS controllers in the braking system, which can control and adjust the wheel braking pressure in real time to prevent the wheel from being locked during the braking process. Braking deviation, rear axle sideslip, and loss of steering ability, etc., enable the vehicle to make maximum use of the ground braking force to decelerate and stop, thereby effectively improving the braking performance of the car and improving the safety of the car. At present, the existing patent achievements and public literature reports are mainly concentrated in the detection field of hydraulic ABS controllers. There are few methods and detection devices for compre...
