EMB (Electro-Mechanical Brake) system that removes hydraulic brake device from conventional brake systems completely can be considered as BbW (Brake-by-Wire) system in the full sense. As the research on the EMB system is actively conducted, it is also required to establish the test methods for the performance verification and evaluation of developed EMB system.

In fact, however, the characteristics of the EMB system makes it difficult to apply it to an actual vehicle test due to the expense and safety matters in the process of the test and evaluation.

Thus, this study developed the EMB HILS (Hardware In the Loop Simulation) system in application of the actual EMB system in order to verify the actuating response characteristics and control logic performance of the EMB system before an actual vehicle test. In addition, for the comparative evaluation of the CBS (Conventional Brake System) that is conventional hydraulic brake system, the CBS HILS system was developed in application of a common ESC module and hydraulic brake device components.

Finally, the performance evaluation of the EMB system and CBS was conducted on the developed EMB HILS system and CBS HILS system, based on which the quantitative evaluation methods and indices to comparatively analyze the performance of the EMB system and CBS is presented.
