ABSTRACT:
A method for stimulating wheel electronics systems of single tires of at least one tire group in a motor vehicle. The wheel electronics systems are stimulated with a low frequency trigger signal, as follows: a trigger signal is emitted from an LF trigger to the wheel electronics systems of the relevant tire group at a variably adjustable first transmission field strength. Radio frequency signals are transmitted from those wheel-side wheel electronics systems, at which a sufficiently high transmission field strength of the trigger signal has arrived containing an item of trigger information, to a vehicle-side receiving unit. A determination is made of the number of RF signals received by the vehicle-side receiving unit, each containing one item of trigger information.
