Method of calibrating a sensor, in particular a yaw rate sensor
Abstract:
The invention relates to a method of calibrating a sensor, in particular a yaw rate sensor, in which sensor values (Ysensor) and associated temperature values (T) are stored in the shape of reference points in a non-volatile memory of the sensor, in which case the values (Ysensor, T) are determined during a calibration mode in which the sensor is exposed to a predefined temperature profile. In order to further improve the accuracy of the calibration, the invention discloses that the values (Ysensor, T) determined in the calibration mode are used to determine coefficients (C0, . . . , Cn-1, Cn) of a polynomial of nth order, and these coefficients are stored.
