Instrument for measuring brake performance of ABS of automobile and detection method

The invention discloses an instrument for measuring the brake performance of an ABS of an automobile and a detection method and belongs to vehicle-mounted fault diagnosis systems in the automotive electronic technology. The instrument for measuring the brake performance of the ABS of the automobile is mainly composed of a vehicle-mounted portable instrument part and an automobile ABS brake performance road test control system. Due to the fact that the instrument for detecting the ABS is researched and developed by means of an attitude sensor which is low in cost, it is becomes possible to obtain a portable instrument capable of detecting the MFDD, the brake coordinate time, the brake performance of the ABS of a motor vehicle and the like, the brake performance of the motor vehicle can be detected conveniently due to the research and development of the instrument, the instrument is low in cost and low in improvement cost and can be completely popularized and applied to motor vehicle safety performance detection mechanisms, the motor vehicle brake performance detecting capacity of a motor vehicle detecting station can be further improved, and management of the sources of vehicles is enhanced.
