Method and device for determining the inclined position of a vehicle

Abstract

The invention relates to a method for determining the inclined position of a vehicle. A rotational speed (?), with a roll rate portion and a yaw rate portion, is detected by means of a sensor (1), the measurement axis (2) of said sensor being inclined by a pitch angle (ß) in relation to the longitudinal axis (3) of the vehicle. A roll angle (f) is finally determined from the rotational speed (?), to describe the inclined position of the vehicle.

Description

technical field [0001] The invention relates to a method for determining the tilt position of a vehicle, in particular a motor vehicle, and a device for carrying out the method. Background technique [0002] The tilted position of the vehicle is generally described by the pivot angle φ. It is known from the prior art to first measure the yaw rate W of the vehicle by means of a yaw rate sensor and to determine the yaw angle φ by subsequent integration of the yaw rate. However, the value determined in this way only represents the value Δφ by which the swivel angle changes during the integration phase. In contrast, without knowing the starting value φ at the beginning of the integration 0 (offset). Therefore, the calculated pivot angle φ has an offset error. In addition, all occurring errors are summed, since the changes in the swivel angle are correspondingly added to form the current value. The swing ratio is thus not long-term stable. A suitable determination of the pi...

Problems solved by technology

This method for determining the swivel angle φ requires two rotational speed sensors and is therefore relatively expensive
