ROTATION RATE OFFSET COMPENSATION

Measurements of rotation rates (10) obtained with a rotation rate sensor (150) on board of a vehicle (200) are corrected by a temperature dependent offset (25). This offset (25) is provided from a table (20). The table (20) may be updated if the vehicle (200) is at rest by determining a temperature...

Zusammenfassung:	Measurements of rotation rates (10) obtained with a rotation rate sensor (150) on board of a vehicle (200) are corrected by a temperature dependent offset (25). This offset (25) is provided from a table (20). The table (20) may be updated if the vehicle (200) is at rest by determining a temperature (15) and determining a rotation rate (10) from the rotation rate sensor (150). Additionally, ageing of the rotation rate sensor (150) may be taken into account. A total error (31) of the corrected rotation rate (30) may also be provided.
