Abstract

In the case of a process for the wireless transmission of energy and data between two parts, preferably the steering wheel and the steering column of a vehicle, having a transformer-type transmitter and consisting of a primary and secondary winding assigned to the parts, and a rectangular carrier frequency on the primary side, the data transmission is carried out in one direction by the modulation of the carrier signal and in the other direction outside the switching flanks of the carrier signal.
