The invention provides an improved vehicle braking energy recovery control method and device, a vehicle and a storage medium. The method comprises the steps: calculating the braking force needed by the vehicle according to the current state of the vehicle when a vehicle controller receives a braking signal, obtaining three control variables, and calculating the three control variables based on animproved genetic algorithm of a prediction model; executing a genetic algorithm under the model prediction control framework; adopting a multi-population combination iteration and average distributionmethod; calculating the three control variable values of the optimal control sequence according to the historical information of the vehicle, generating a multi-dimensional dot matrix based on an input set, and selecting a control variable closest to the current state in the dot matrix when the vehicle is braked; According to the motor regenerative braking torque of the optimal control variable,the vehicle control unit sends a control signal to the motor and a controller thereof to control the motor to output the corresponding braking torque. The safety of the whole vehicle is guaranteed under the emergency braking working condition, and braking recovery energy is improved under the conventional braking working condition.
