Abstract
The invention relates to a device for the inductive transfer of electric energy from a stationary unit comprising at least one primary inductance to a vehicle that is adjacent to said unit and has at least one second inductance. The stationary unit or the vehicle has a device for detecting the presence of an object in a predetermined area that covers at least the area lying between the primary inductance and the second inductance during the inductive energy transfer. The detection device has at least one contactless sensor and an evaluation unit that is connected to the sensor. At least the sensor of the detection device is integrated into or mounted on the same housing as the primary or secondary coil of the energy transfer device. The sensor can be an ultrasonic sensor, radar sensor, infra-red sensor or an electric image sensor.
