Abstract:
1. A method for self-adjustment of a triaxial acceleration sensor during operation using a computing unit including an estimator, comprising: identifying, using the computing unit, a rest state of the acceleration sensor based on an output voltage of the sensor, directional sensitivities of the acceleration sensor included in a sensitivity matrix, and an offset; identifying whether acceleration values from the acceleration sensor are new values using the computing unit; calibrating the sensor using the computing unit for sensitivity and offset with the aid of calibration values when the acceleration sensor is in the rest state using the identified new values; checking for an interfering acceleration, with the aid of a measurement equation and estimated values for sensitivity and offset using the computing unit, wherein the checking includes: repeating the calibrating using the computing unit if an interfering acceleration is recognized; and accepting the estimated values for sensitivity and offset as calibration values if an interfering acceleration is not recognized.
