Problems solved by technology

This kind of road test can truly reflect the implementation of automobile ABS, but due to the high construction cost of the test track, the test requires professional car testers, so the test cost is high, and there is a certain risk in the test
The latter uses instruments to statically test the components of the ABS, but the static characteristics of the components are fine, which does not guarantee the normal function of the ABS.

Abstract

A sticking-on proof brake system of automobile is prepared as connecting microprocessor to monolithic computer (MC) through serial communication module and output end of MC to input end of ABS wheel speed signal analog module, connecting output end of said analog module to controller of sticking-on proof brake system, collecting regulator control signal by ABS valve-control signal collection module and sending data to microprocessor, connecting input end of ABS data sampling module to said controller and connecting output end of said sampling module to input end of microprocessor.

Description

technical field [0001] The invention relates to a performance detection device and detection method of an automobile anti-lock braking system (ABS) and its controller (ECU), and belongs to the performance detection device and detection method of an automobile anti-lock braking system and its controller Innovative Technology. Background technique [0002] At present, my country's automobile main engine factories and automobile ABS production plants mainly have two methods for performance testing of mass-produced automobile ABS: road test and static test. The former assembles ABS components on cars and performs braking tests on special car test tracks. , Judging by the driver's feeling whether the ABS is working normally. This kind of road test can truly reflect the implementation of automobile ABS, but due to the high construction cost of the test track, the test requires professional car testers, so the test cost is high, and there is a certain risk in the test. The latter ...
