Abstract

In a transmission method for variable parameters from loaded vehicle wheels, wherein energy is transmitted to a secondary coil (5) mounted concentrically on a wheel during varying excitation by a primary coil (2) integral with a vehicle, and an information signal, which is a function of the output signal of a sensor, is fed back from this secondary coil to a receiving coil integral with the vehicle, the primary coil (2) itself serves as the receiving coil. The information signal can be temperature-compensated, and compared in an evaluation circuit with a set value which is modified in accordance with various pressure-related parameters.
