The performance of ESC system is greatly influenced by vehicle design factor and tire performance. But many car maker develop the vehicle can have variability to meet the variety consumer requirement of several countries. ESC system also should be developed with considering the chassis configuration of vehicle and being satisfied the requirement. So, robust control algorithm and value-added-function regarding market requirements are required. The more variant vehicle has, the more complex validation test in vehicle level become. Test for the evaluation of ESC performance in real vehicle is time consuming and required much cost. Therefore, many evaluation processes is replaced by laboratory test such as hardware in the loop simulation. HILS (Hardware in the loop simulation) is the computer simulation include real hardware control unit in simulation loop. It is useful tool to test and validate these controllers in phase of development. This paper described the outline of HIL simulation for ESC performance evaluation and the process of HIL simulator development is explained, then interface model is introduced between real time platform and hardware system. Finally, automated system application for the change of factor influencing ESC performance is presented.
