Sensor system and procedure for monitoring/measuring vehicle tyre adhesion on a surface and other physical data of the tyre

摘要

The system measures the force between a vehicle tyre and the track and may provide sensor signals for further tyre data. The system has a radio interrogation device (9) with an antenna (200) for output high frequency interrogation pulses and to receive the response signals. A radio sensor (10) with antenna (100) is built into the tyres. The radio sensor is formed such that it stores the energy of a respective interrogation pulse in the memory (70) and provides a corresponding response signal delayed in time, which contains the respective sensor signal. This signal is to be received in the interrogation unit from the pulse undistorted, and is processed to a measurement result.
