ABS实时四轮轮速信号采集系统

Abstract

Abstract:

A method using automobile selfprovided collection system to collect wheelspeed signal from anti\|lock braking system (ABS) was studied. After collection of it from the ABS wheelspeed sensor, the signal was separated, enlarged, filtered, integrated, followed by computer collection, wheel speed calculation and other series data processing, the automobile wheel speed was got accurately and fast. This method has been widely applied to field experiment for all types of automobile by State Key Laboratory of Automobile Dynamic Simulation of Jilin University. Experiment results show that this method is precise, constant, easyinstallation and feasible to every type of automobile.

Key words: antilock braking system, operational amplifier, filter, lagging comparator
