Method and device for determining a signal offset of a roll rate sensor
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).
Abstract(Chinese):

为了确定车辆（10）中的滚动率传感器的信号偏移（OFS_SIG），检测到滚转速率传感器信号（OMEGA_ROLL_SIG）。 确定车辆（10）的横向加速度（AC）。 确定横向加速度（AC）的时间导数（DRV_AC）。 验证横向加速度（AC）的时间导数（DRV_AC）的值是否小于预定义的第一阈值（THD-1）。 如果横向加速度（AC）的时间导数（DRV_AC）的值小于预定义的第一阈值（...），则根据滚动速率传感器信号（OMEGA_ROLL_SIG）来确定滚动速率传感器的信号偏移（OFS_SIG） THD-1）。
