Abstract
In order to determine a signal offset (OFS_SIG) of a roll rate sensor in a vehicle (10), a roll rate sensor signal (OMEGA_ROLL_SIG) is detected. A transversal acceleration (AC) of the vehicle (10) is determined. A temporal derivative (DRV_AC) of the transversal acceleration (AC) is determined. Verification is made as to whether a value of the temporal derivative (DRV_AC) of the transversal acceleration (AC) is smaller than a predefined first threshold value (THD—1). The signal offset (OFS_SIG) of the roll rate sensor is determined in accordance with the roll rate sensor signal (OMEGA_ROLL_SIG) if the value of the temporal derivative (DRV_AC) of the transversal acceleration (AC) is smaller than the predefined first threshold value (THD—1).
