Device for combined detection of axle acceleration and wheel rotational speed and method for determining pressure |
摘要 |
The pressure in a motor vehicle tire can be determined by means of a 'wheel-independent' device (1) that is in a largely rigid manner connected mechanically to an element (2) of the vehicle body (3, 14) oscillating with the motor vehicle wheel (4). In order to determine the-preferably absolute-tire pressure by combining the evaluation of rotational speed data and axle frequency analysis, said device (1) includes a signal pre-processing element (6) provided with electronic components for processing the sensor signals, said element being connected to a magnetic sensor element (7) and an acceleration sensor element (8) or to a combined magnetic/acceleration sensor element (5) by means of an electrically conductive element connection (9), wherein the magnetic sensor element (7) or the magnetic/acceleration sensor element (5) is operatively connected to a magnetic encoder (16) arranged on the wheel side. To improve determination of characteristic quantities, preferably the vibration behavior of at least two wheels (4) is analyzed.
