Contact sensor for vehicle comprises sensors and evaluation and control unit for evaluating knocking sensor signals using knocking recognition algorithms for recognizing a collision with a pedestrian

摘要

Contact sensor comprises sensors (12, 14) and an evaluation and control unit (200) for evaluating knocking sensor signals using knocking recognition algorithms for recognizing a collision with a pedestrian. The evaluation and control unit recognizes a collision with a pedestrian when an internal signal formed from the sensor signals corresponding to a relative knocking intensity exceeds a prescribed trigger threshold. Preferred Features: A signal spreading switch (100) spreads the knocking sensor signal of the sensor and produces an integrator signal (IS) which is evaluated by the evaluation and control unit. The evaluation and control unit produces control signals for controlling the switch.
