Study on the brake pedal control model for regenerative braking integrated system

摘要

Brake pedal movement signal is the only way for the driver to transmit the brake demand, in the combined braking system of regenerative braking and hydraulic braking. It is prone to bring fluctuations between the mechanical brake and electric brake system, resulting in a poor brake pedal feel. In this paper, the traditional purely hydraulic braking pedal features is taken as the research object, the brake pedal control model of regenerative braking integrated system is established by using trajectory tracking control strategy. The simulation results show that, the model can achieve a predetermined vehicle brake pedal feel, and we can get the brake demand and pedal feel demand by the resolve of brake pedal state motion, the research can also provide a theoretical basis for the design of regeneration brake pedal system, including the electric vehicle and hybrid vehicle.
