Verfahren zur Eichung eines Einpunktaufprallsensors
摘要
<p>A method for calibrating an impact sensor enables calibration to take place after sensor manufacture is completed. During calibration, the sensor undergoes an acceleration while vehicle specific calibration values are programmed into sensor memory for different incremental rates of acceleration. Calibration verification checks to verify that the relationship between acceleration and sensor output is linear. The calibration also includes a hysteresis test by comparing output values when incrementally increasing the acceleration to corresponding acceleration values while incrementally decreasing acceleration. The calibration method may also include calculating a response time for a self-test circuit that can be stored in memory and later used during self-tests of the sensor.</p>
