Abstract

The invention discloses a development experimental platform for detecting and controlling an automobile tire pressure ABS (Anti Lock Brake System) / ASR (Acceleration Slip Regulation) key part. The development experimental platform is an experimental platform which integrates an ABS / ASR fault detecting function with a development function of a control unit, is specially developed for a tire pressure ABS / ASR system and is suitable for application. The development experimental platform consists of a mechanical system, a brake wheel cylinder simulation system, a human-machine interaction system, a signal control system, a signal acquisition system and a wheel speed simulation circuit system. According to the development experimental system, a real automobile brake hub is replaced by adopting the brake wheel cylinder simulation system, so that the development experimental system becomes the signal control system based on an xPCTarget real-time technology. In a control interface, the fault code setting of a control unit can be automatically modified according to the requirement; and a control strategy of the control unit can be developed by using a dynamical model.

Description

technical field [0001] The invention relates to a test device for detecting key components of an automobile air pressure ABS / ASR system and developing vehicle brake anti-skid and driving anti-skid control functions, in particular to an experimental platform for detecting and controlling key parts of an automobile air pressure ABS / ASR system. Background technique [0002] At present, in the prior art, there are many devices for ABS / ASR system test benches, but there are many devices for hydraulic systems, and there are few test benches specially invented for pneumatic ABS / ASR systems. Moreover, the current ABS / ASR test and development test benches are mainly divided into two categories: the first category is the ABS / ASR performance test based on the real vehicle, and the test purpose is achieved by placing the driving wheels of the real vehicle on the test bench. This kind of test bench is not only easily restricted by time, site, vehicle and other conditions, but usually doe...
