aufprallsensor with at least two mutually beabstandeten electrodes and method for aufprallerkennung and triggering of devices with such a aufprallsensor

摘要

the invention relates to a aufprallsensor with at least two mutually beabstandeten electrodes and a method for aufprallerkennung and triggering of devices with a solcmr aufprallsensor.such a aufprallsensor to aufprallerkennung is usually from a first, aufprallrichtung (f) front electrode (e1) and at least one secondin aufprallrichtung (f) beabstandeten second electrode (e2).with the first and second electrode at least in a aufprallrichtung (f) vertical transverse (y) of the aufprallzone corresponding querlänge) and a aufprall the strength of the front electrode (e1) and the second electrode (e2) is deformed, and an electrical evaluation circuitry is provided.from the contact of the two electrodes (e1, e2), a collision is detected.the second electrode (e2) is an electrical impedance.which is at least a factor of 2 is greater than the electrical impedance of the first electrode (e1) and is located on the second electrode (e2), a known voltage (vin).also provided is a strommessmittel, which the flow of current (in).the second electrode (e2) is collected and a drop is provided, which, moreover, the voltage (vm) between the first and second electrode is collected.
