Research on Regenerative Braking Combined Control Method for ESP of Pure Electric Vehicles

Through the analysis of the regenerative braking system of pure electric vehicles, a series type of regenerative braking control strategy based on a full decoupling braking system is proposed from the perspective of vehicle braking dynamics. The main factors influencing the regenerative braking control of pure electric vehicles are analyzed. Based on this, several common braking control strategies of regenerative systems are elaborated and analyzed according to the main influencing factors. Through the comparative analysis of the braking control strategies of the regenerative system, it is found that the parallel linkage brake control strategy can better meet the safe operation of pure electric vehicles. Compared with the original control strategy, the regenerative braking combined control strategy can improve the energy recovery rate when the vehicle is braking at high braking intensity and it can also improve the failure safety of the electronic control system when the vehicle is braking at high speed or at medium and high intensity.
