Abstract (en)
[origin: WO03031990A1] The pressure of a motor vehicle wheel can be determined by means of a device (1), independent of the wheel mechanically fixed to an element (2) of the body (3, 14) of the vehicle oscillating with the wheel (4). In order to determine tyre pressure, preferably absolute pressure, by combining the evaluation of data concerning the rotational speed and analysis of axle frequency, said device (1) comprises a signal preprocessing unit (6) provided with electronic components for processing sensor signals, said unit being connected to a magnetic sensor element (7) and an acceleration sensor element (8) or to a combined magnetic/acceleration sensor element (5) by an electrically conductive connection (9). The magnetic sensor element (7) or the combined magnetic/acceleration sensor element (5) is operatively connected to a magnetic encoder (16) arranged on the wheel side. In order to improve determination of characteristic quantities, the oscillating behaviour of at least two wheels (4) are analysed.
