8 Analysis of the Regenerative Braking System for a Hybrid Electric Vehicle using Electro-Mechanical Brakes Ki Hwa Jung, Donghyun Kim, Hyunsoo Kim and Sung-Ho Hwang Sungkyunkwan University Republic of Korea 1. Introduction In the future, automobile makers will be required to produce new technologies that reduce automotive emissions while still satisfying the ever increasing performance demand of drivers. Active safety control systems such as Anti-lock Brake System (ABS), Electronic Braking force Distribution (EBD), Traction Control System (TCS) and Electronic Stability Program (ESP) need to improve their existing braking functions in order to be truly effective in improving driving safety. Therefore, brake systems will need to be faster and more sophisticated when controlling braking forces at the wheels. In addition, smaller pedal pressure and reduced stroke will be required to produce a larger braking force. With ABSs, the surge and fluctuation of pedal force gives the driver an uncomfortable feeling. These are only a few of the problems and technical limitations of current braking control systems (Semm et al., 2003, Peng et al., 2008). Figure 1 shows the development trend of braking control systems. The future development in braking technology will progress towards brake-by-wire; therefore, brake manufacturers will need to take a greater interest in the development of Electro-Mechanical Brake (EMB) systems (Line et al., 2004, Emereole
