Abstract
The hardware in-the-loop simulation (HILS) system has historically been used in the development and testing of complex and costly systems such as military tactical missiles, aircraft flight control system, satellite control systems, and automotive systems. Especially in the automotive industry, HILS is an effective tool for design, performance evaluation and test of vehicle subsystems such as antilock brake system (ABS), active suspension system, and steering system. This paper describes a HILS model for an ABS/ASR application. Also the design and implementation of HILS system for development of the ABS ECU (electronic control unit) for commercial vehicles are presented. Fourteen degrees of freedom vehicle dynamics model is simulated in alpha-chip processor board. The proposed HILS system is tested by a basic ABS control algorithm. The HILS system simulation results show that the proposed HILS system maybe used to realistically test performance, stability, and reliability of the vehicle.
