Modeling of comprehensive electric drive system for a study of regenerative brake system

Regenerative brake system is more complicate compared to a conventional brake system since its design and control goals require not only to achieve a good braking performance but also to recover brake energy as much as possible. In this paper, a comprehensive regenerative brake system model has been developed for a study of brake performance and effective regenerative brake energy recovery. This paper presents a detailed modeling of electric drive system, design of a brake force distribution, and effective brake force allocation between motor brake and friction brake forces. The performance of a proposed model has been evaluated using a commercially available full vehicle model (CARSIM) through simulation.
