The invention discloses a vehicle energy recovery control method and device, and relates to the field of new energy vehicle energy recovery, and the method comprises the steps: based on the obtained road information in front of a vehicle, when it is judged that the vehicle has a braking intention, carrying out the calculation of braking energy; according to the braking energy obtained through calculation and the braking distance obtained according to the information of the road in front of the vehicle, the braking torque of the motor is obtained through calculation; and according to the calculated braking torque of the motor, feedback braking control is carried out, so that vehicle energy recovery is achieved. According to an intelligent feedback brake triggering and control mechanism based on brake energy prediction, invalid sliding brake control is avoided; energy recovery control in a sliding intention, braking intention and sliding intention forbidding scene is identified, and the efficiency loss in the energy conversion process is reduced; and energy recovery control under the braking intention scene is conducted, full-decoupling type regenerative braking energy recovery is achieved, and mechanical braking energy loss is reduced.
