Approach of Debugging Control Laws of ABS Combined with Hardware-in-the-Loop Simulation and Road Experiment 2001-01-2729

Anti-lock Braking System (ABS) is an important control system that can improve the automotive performance, reliability and safety obviously. Hardware-in-the-loop Simulation (HILS) testing is a promising method to assistant design automotive electronics system. In the State Key Laboratory of Automotive Safety and Energy, a HILS system was established to assistant design ABS. The HILS system is composed of a hydraulic control unit of ABS, a normal brake system, a commercial personal computer, a data acquisition card, and several signal-conditioning modules. Powerful software was programmed to perform managing input and output signals, solving 7-freedom and 15-freedom vehicle models, and acquiring response signals of the brake system.
Based on the simulations of HILS system, the road experiments with the same conditions of ABS are very necessary and important. In this method, the combination of HILS and road experiment rapidly reduce the cycle of design and debugging the control laws of ABS in automobile.
