  • Patent number: 8065104
    Abstract: An inertial measurement unit (IMU) contains three linear acceleration sensors and three rotational speed sensors. For the sensors there are desired installation directions parallel to the co-ordinate axes of a Cartesian co-ordinate system which is fixed to the vehicle. The actual installation directions of the sensors may differ from the desired installation directions owing to incorrect orientations. By comparing accelerations which are measured by the linear acceleration sensors for different attitudes of the vehicle with acceleration values which are known for these different attitudes in the Cartesian co-ordinate system which is fixed to the vehicle, the actual installation directions of the linear acceleration sensors are determined. By using a co-ordinate transformation it is then possible to convert the measured accelerations into the actual accelerations.

  • Patent number: 8024086
    Abstract: For determination of a relative movement of a chassis and a body of a wheeled vehicle, which is movably joined to the chassis, three linear accelerations of the wheeled vehicle, which extend perpendicular to each other, respectively, as well as at least two rotational speeds of one respective rotational movement or a component of a rotational movement about a coordinate axis of the wheeled vehicle are measured (in measuring device 1), the at least two coordinate axes running perpendicular to each other, respectively. A momentary position of the relative movement is determined (in evaluation unit 9) using the three linear accelerations and the at least two rotational rates.

  • Publication number: 20110004359
    Abstract: In order to determine a signal offset (OFF_SIG) of a pitch rate sensor of a vehicle (2), a signal (OMEGA_TETA_SIG) from the pitch rate sensor is detected. Longitudinal acceleration (ACC) of the vehicle (2) is determined. A time derivative (ACC_DRV) of the longitudinal acceleration (ACC) is determined. A check is carried out in order to determine whether a magnitude of the time derivative (ACC_DRV) of the longitudinal acceleration (ACC) is less than a first predefined threshold value (THD—1). The signal offset (OFF_SIG) of the pitch rate sensor is determined on the basis of the signal (OMEGA_TETA_SIG) from the pitch rate sensor if the magnitude of the time derivative (ACC_DRV) of the longitudinal acceleration (ACC) is less than the first predefined threshold value (THD—1).

  • Patent number: 7522985
    Abstract: For monitoring of a measuring device (1), located in a wheeled vehicle, the measuring device (1) is configured so as to measure three linear accelerations (in unit 3) of the wheeled vehicle, which extend perpendicular to each other, respectively, as well as three rotational speeds (in unit 4) and one respective rotational movement or a component of a rotational movement about an axis of the wheeled vehicle, the three axes running perpendicular to each other, respectively. At least components of an orientation of the wheeled vehicle in a vehicle-external coordinate system are determined (in unit 7) from the three rotational speeds, and at least one of the measured linear accelerations is monitored (in unit 9) using at least the components of the orientation and a comparative variable (from unit 8).
