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.

Abstract: A blind spot sensor system detects and/or classifies objects in a defined monitoring region of a motor vehicle. The blind spot sensor system contains a first device for emitting a first radar beam, and a second device for emitting a second radar beam. The radial visual range of the first radar beam (beam I) inclines counter to a direction of travel of the motor vehicle and the radial visual range of the second radar beam (beam II) is oriented in an substantially vertical manner in relation to the direction of travel such that the visual range of the radar beams (I and II) at least partially overlap and cover, substantially, the monitoring region. At least the first radar beam (beam I) can be actuated in a CW modulation mode and in a FMCW modulation mode. The blind spot sensor is used in vehicles, for example for assisting in lane changing.
