Abstract
A method for determining a tilt angle of a vehicle includes measuring accelerations of a vehicle in directions along a longitudinal axis, a transverse axis, and a vertical axis of the vehicle. A current tilt angle of the vehicle is calculated as a function of the measured accelerations. A magnitude-compensated tilt angle is calculated as a function of the current tilt angle, of a preceding tilt angle, and of the magnitude of the vector sum of the measured accelerations. A gyroscopically stabilized magnitude-compensated tilt angle is calculated as a function of the current tilt angle, of a preceding tilt angle, of the magnitude of the vector sum of the measured accelerations, and of a change in the tilt angle over a given time period calculated from angular rate data provided by a gyroscope.
