Method and device for operating a system for monitoring and wirelessly wirelessly signalling a pressure change, and for automatically regulating the pressure in pneumatic tyres on vehicles
First Claim
1. A method for operating a device for monitoring and wirelessly signalling a pressure change, and for automatically regulating the pressure in pneumatic tyres on vehicles, wherein the pressure information for the electronic tyre pressure regulating system is provided by a sensor unit inside the tyre, the loading state of the vehicle is automatically determined and in the event of deviations of the actual value of the tyre pressure from the desired value depending on the weight loading, the tyre pressure is corrected to the desired value, characterized in that during the journey respectively with the engine running and with the wheels simultaneously at a standstill, the axle loads are determined in time steps and the last value of the axle load is used as the current actual value for calculating the desired value of the tyre pressure.

Abstract
The invention relates to a method for operating a system for monitoring and wirelessly signalling a pressure change, and for automatically regulating the pressure in pneumatic tyres on vehicles. The invention is characterised in that an electronic sensor mechanism (12) inside the tyre provides pressure information for the electronic tyre pressure regulation system. This enables both an increase in the reliability and the safety of the wheel system and an improvement in the driving dynamics.
