Abstract
A method for controlling an electromotive drive of a motor vehicle. At least one of the motor vehicle wheels can be driven by an electric motor of the electromotive drive and the electromotive drive has at least one energy source for the electric motor. The method includes: identifying a request for applying a deceleration torque to the vehicle wheel, identifying status of the electromotive drive, selecting an operating mode of the electric motor according to the identified status, and controlling the electric motor in the selected operating mode for applying the deceleration torque. In a first operating mode, the electric motor is controlled such that the rotational energy of the vehicle wheel is converted at a first efficiency into electrical energy. In a second operating mode, the electric motor is controlled such that the rotational energy of the vehicle wheel is converted at a second efficiency into electrical energy.
