As the vehicle electronic control technology grows fast and becomes complicated, a more efficient way than the traditional in-vehicle driving test is demanded for extensive testing of ECUs. For this purpose, hardware-in-the-loop simulation(HILS) scheme is very promising since it can replace significant portions of actual driving test procedures. It incorporates hardware components of prime concern in numerical simulation environment, yielding results with better credibility than pure numerical simulations. HILS runs in real time and it provides time-and cost-effectiveness over actual driving test. It also makes possible test procedures that are difficult or even impossible in actual driving tests. In-vehicle driving tests for evaluating performance of vehicle control devices are often time-consuming, expensive, and not reproducible. Using hardware-in-the-loop simulation scheme, actual control devices can be easily tested in real time in a closed loop with a virtual vehicle. This advantage has made HILS systems popular as testbench lately in automotive industries. This paper describes a PC-based HILS system for ABS that has been developed in Matlab environment with realtime rapid prototyping tools. Also presented in this paper is a semi-empirical vehicle dynamic model that has been designed to account for kinematic and compliant characteristics of the suspension system from rig tests.
