Abstract

The invention provides a vehicle sliding energy recovery triggering method and device, electronic equipment and a storage medium, and the method comprises the steps: determining the sliding speed of avehicle at a current moment when the vehicle is detected to enter a sliding state; acquiring the sliding speed of the vehicle at the historical moment; determining the sliding speed at the moment tobe estimated according to the sliding speed at the current moment, the sliding speed at the historical moment and the sliding speed prediction model; determining wheel-side required braking torque based on the sliding speed at the current moment and the sliding speed at the moment to be estimated; determining motor end required braking torque according to the vehicle attribute information and thewheel edge required braking torque; and sending the braking torque required by the motor end to the motor, and triggering the motor to recover sliding energy. Thus, the sliding energy can be properlyrecovered, the driving feeling cannot be affected by excessive recovery of the sliding energy, and the energy recovery efficiency cannot be low due to excessive recovery of the sliding energy.

Description

technical field [0001] The present application relates to the technical field of automobiles, and in particular to a method, device, electronic device and storage medium for triggering vehicle coasting energy recovery. Background technique [0002] Hybrid vehicles are the mainstream of the current development of new energy vehicles. The coasting energy recovery function is an essential function of hybrid vehicles. When the vehicle is running, the energy of coasting is recycled to the energy storage unit through the motor to provide power for the subsequent power demand. . The current braking and coasting energy recovery strategy of intelligent driving vehicles is generally controlled based on the driver's intention. When encountering a red light or other road conditions in the city, the driver completely releases the accelerator pedal to keep the vehicle coasting. The coasting inertia of the vehicle is used to drive the generator to generate electricity, so as to recover th...
