Design of Energy-Regenerative Braking Systems

The design of energy-regenerative braking systems requires clear understanding of the relationship between existing friction braking and added motor regenerative braking, as well as the interactions among vehicle control unit, motor control unit, and brake control unit. A significant challenge lies in enabling the friction braking system to regulate pressure independent of brake pedal input for real-time friction braking force control. This chapter introduces the overall scheme of regenerative braking systems and various schemes for hydraulic and pneumatic friction braking force adjustment mechanisms.
