Regenerative braking is one of the core technologies to improve the economy of pure electric vehicles. To realize the improvement of the energy recovery effect under conventional braking conditions and the coordinated control between regenerative braking and anti-lock system under emergency braking conditions of pure electric vehicles, this paper studies a front and rear axle braking force distribution method with the actual road adhesion coefficient and braking strength as the premise, while using fuzzy control to distribute the front axle electromechanical braking force. The sliding mode controller with double power convergence law is designed to enhance the stability of the anti-lock system. Finally, the braking coordination control strategy is proposed by combining the designed regenerative braking and anti-lock control. Through simulations and experiment, it has been proved that the control strategy is effective and can effectively improve the economy of pure electric vehicles.
