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.
