The invention relates to the technical field of electric vehicles, and discloses an electric vehicle energy recovery control method and device, an apparatus and a storage medium. The method comprisesthe following steps of acquiring a brake pedal opening signal of a target electric vehicle, and obtaining the driving speed data and tire rolling angular speed data of the target electric vehicle; determining a target energy recovery torque according to the brake pedal opening signal; and starting the energy recovery of the target electric vehicle based on the target energy recovery torque; calculating the current slip rate of the wheel of the target electric vehicle according to the driving speed data and the tire rolling angular speed data; judging whether to continuously recover energy or not according to the current slip rate, the running speed data and the tire rolling angular speed data, so that the energy recovery is started according to the brake pedal opening degree signal, the slip rate is calculated, whether energy recovery is continuously carried out or not is judged according to the slip rate, and the technical problems of how to reasonably control the energy recovery of the electric automobile and how to improve energy recovery safety, are solved.
Description
technical field [0001] The present invention relates to the technical field of electric vehicles, in particular to an electric vehicle energy recovery control method, device, equipment and storage medium. Background technique [0002] In order to improve the efficiency of electric energy utilization, electric vehicles will be equipped with energy recovery function, that is, when the vehicle brakes or coasts, and the power battery meets the charging permission conditions, the motor controller controls the driving motor to enter the charging mode, and converts mechanical energy into electrical energy and feeds it back to the At this time, the driving motor will apply braking torque to the driving wheels through the transmission system. At the same time, for safety reasons, electric vehicles will be equipped with anti-lock braking devices, and the anti-lock braking devices will be on the wheels Reduce the braking torque applied to the wheels immediately before locking.
