Study on a new kind of electromagnetic mechanical coupled regenerative braking system for electric vehicles

Abstract

Electric vehicles technology is an effective way to solve the automobile energy and pollution problems, and regenerative braking is one of the advantageous technologies to achieve electric vehicles high braking energy recovery and to improve the energy efficiency. On the basis of electromagnetic theory and braking energy flow analysis, combined with modern advanced electromechanical control technology, we put forward a new kind of electromagnetic mechanical coupled braking system (EMCB), and make simulation experiments for longitudinal stability control of the system. The results showed that: the proposed ABS continuous state control strategy based on the new EMCB system improved the shortcomings of the traditional ABS discrete switch control, and avoided the high frequency chattering vibration of the system, with good response, robustness and slip rate control performance, which improves the braking energy recovery and braking comfort and effectively increases the driving range of electric vehicles.
