Method for detecting impact by elastically deformable hollow body and pressure sensors, involves providing signals of both pressure sensors with positive pressure pulse during collision, where signals are reviewed at negative pressure pulse

摘要

The method involves providing the signals of both pressure sensors with a positive pressure pulse during a collision and comparing the signals of both pressure sensors to each other. The signals are reviewed at a negative pressure pulse. A defect of a hollow body is detected, when the positive pressure pulses of the signals of both pressure sensors differ to more than a predetermined amount and when one signal of the two pressure sensors has the negative pressure pulse of predetermined strength.
