Abstract:
1. A triggering device for a safety device in an automotive vehicle, the triggering device comprising: an electrical component that has at least one force sensor and that is attached to the body of the automotive vehicle in such a way that a measurement signal that is dependent on the deformation of the body is applied at a measurement signal output of the force sensor; and an evaluation device that is used to process the measurement signal and that is connected to the measurement signal output, wherein the force sensor has at least one piezo element that, together with the evaluation device, is monolithically integrated into a CMOS chip, wherein the evaluation device has a nonvolatile data memory in which at least one triggering characteristic value is stored, the evaluation device has a comparison device to compare the at least one triggering characteristic value with the measurement signal, and wherein the evaluation device is configured such that the triggering signal is generated depending on the result of this comparison.
