Abstract:
1. A method for the measurement of acceleration, the values of acceleration applied to the sensor being within the sensor measurement range, in the direction of three dimensions using a micromechanical acceleration sensor, which acceleration sensor comprises at least four units of sensor measurement devices measuring in different measurement directions, of which four vectors describing the measurement directions of the sensor measurement devices no three vectors belong to the same plane, wherein in the method, the continuous self-testing of the acceleration sensor during start-up and/or operation is implemented such that to the accelerations {right arrow over (a)} the accelerations {right arrow over (a)} the value of the expression k the value of said expression is compared to a pre-defined threshold value, and if the value of said expression deviates from the value {right arrow over (0)} more than said pre-efined threshold value, an error message is given.
