In order to solve the limitations and complexity of a pressure coordinated control system for hybrid regenerative braking, a new pressure coordinated control system applicable for a regenerative braking system of hybrid electric vehicles is proposed in this paper based on an appropriate transformation on a traditional hydraulic braking system equipped with an antilock braking system (ABS). The system can realize regenerative braking and traditional ABS braking simultaneously. It also has greatly improved driver's brake pedal feel. The system model has been simulated and analyzed based on AMESim-simulink cosimulation. The simulation results show the effectiveness and feasibility of the system, which lay the foundation for design and optimization of the regenerative braking system.
