Hardware-in-the-loop simulation for ABS based on PC

The prevalence of microprocessor-based controllers in automotive systems ha s greatly increased the need for tools which can be used to validate and tu ne the control systems over their full range of operation. The objective of this paper is to develop a real time simulator for an anti-lock brake syst em (ABS) based on the methodology of hardware-in-the-loop simulation using a personal computer. By use of this simulator, the analysis of a commercial electronic control unit as well as the validation of the developed control logic for ABS was performed successfully. The idea of the simulator can be applied to the development of more advanced control systems, such as tract ion control system, vehicle dynamic control system and so forth.
