Abstract:
1. A method for operating a wheel electronics system of a tire checking system for a vehicle, the wheel electronics system being located on a wheel of the vehicle, the method comprising the following steps: providing a controllable, battery-free power supply having at least one rechargeable power storage medium located on the wheel in the wheel electronics system for supplying power to the wheel electronics system, the wheel electronics system including a control device located on the wheel configured to operate the controllable, battery-free power supply of the wheel: determining data relating to tire-specific parameters with the wheel electronics system; and transmitting the data to a vehicle-mounted communication device as modulated transmission signals, with less transmission power being used for the transmission signals in the power-reduced transmission mode than in the normal transmission mode, the transmission signals in the first, power-reduced transmission mode being modulated according to a first modulation method and the transmission signals in the subsequent normal transmission mode being modulated according to a second modulation method different from the first modulation method.
