Method for self-adjustment of a triaxial acceleration sensor during operation, and sensor system having a three-dimensional acceleration sensor |
摘要 |
A method for self-adjustment of a triaxial acceleration sensor during operation includes: calibrating the sensor; checking the self-adjustment for an interfering acceleration, with the aid of a measurement equation and estimated values for sensitivity and offset; repeating the adjustment 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. The step of checking the self-adjustment includes: estimating sensitivity and/or offset and the variance thereof; determining an innovation as the difference between a measured value of the measurement equation and an estimated value of the measurement equation; testing the innovation for a normal distribution; and recognizing the interfering acceleration in the event of a deviation from the normal distribution.
