The embodiment of the invention discloses a method and device for regulating and controlling the energy recovery intensity of a vehicle, and the method comprises the steps: obtaining the road condition information of the vehicle and a first vehicle speed when the opening degree of an accelerator pedal of the vehicle is detected to be smaller than a preset threshold value in the driving process of the vehicle; determining a deceleration scene according to the road condition and the first vehicle speed, wherein the deceleration scene is used for identifying that the vehicle is decelerated from the first vehicle speed to a second vehicle speed after a target distance; according to the target deceleration and the difference value between the current deceleration of the vehicle and the target deceleration, the target energy recovery intensity is calculated, and when the target energy recovery intensity is larger than the preset energy recovery intensity of the vehicle, the energy recovery intensity of the vehicle is regulated to be the target energy recovery intensity, so that the energy recovery intensity of the vehicle is adjusted to be the target energy recovery intensity in the sliding stage of the vehicle. Energy recovery can be performed according to the target energy recovery intensity, and compared with the preset energy recovery intensity, more energy can be recovered, so that the sliding energy recovery efficiency of the vehicle is improved.
