Abstract:
An internal-to-vehicle mechanism for monitoring an air pressure of a tire of a vehicle, comprising:an electrotechnical first device;a sensor detecting the tire air pressure, the sensor rotating, together with the first device, synchronously with a wheel of a vehicle, the sensor modifying at least one of a first magnetic field energy uptake and a first electromagnetic field energy uptake of the first device as a function of the detected tire air pressure;a stationary electrotechnical second device radiating an electromagnetic field, the first device passing through the electromagnetic field; anda monitoring device coupled to the second device and for detecting at least one of a second energy uptake and an energy release relating to a second energy of the second device, wherein the second energy is used to build up at least one of a magnetic field and the electromagnetic field, and wherein at least one of the sensor and the first device is adapted to being arranged on a pulse ring of an antilock braking system device rotating synchronously with the tire.
