Abstract
A system for the wireless transmission of information and energy between a removable vehicle seat and the vehicle body, in which the vehicle seat is detected by measuring the inductance. In this connection, the period of an oscillating circuit is determined, in which the winding of the primary side, and thus the inductance, is connected. In this context, the frequency of the resonance voltage is determined as a function of time. In this context, the zero crossings of the resonance voltage is measured. Alternatively, the secondary side impedance is additionally measured on the primary side by a forced oscillation, namely by a voltage decay in a resonance circuit in which the winding is connected as inductance. A monitoring of the performance reliability of a firing pellet is thereby implemented.
