Abstract

An internal-to-vehicle mechanism for monitoring the air pressure of a tire of a vehicle includes a sensor, detecting the tire pressure, which rotates, together with an electrotechnical first device, synchronously with the wheel and which, as a function of the tire air pressure that is determined, modifies parameters of the first device, namely the energy uptake of the first device. A stationary electrotechnical second device radiates an electric and/or magnetic, in particular electromagnetic, field through which the first device passes at, preferably, each wheel rotation with an uptake of energy from the field. A monitoring device detects the energy uptake and/or energy release of the second device.
