SENSORSYSTEM UND SENSORELEMENT SOWIE VERFAHREN ZUM ÜBERWACHEN EINES SCHLIEßMECHANISMUS

摘要

Disclosed is a sensor system comprising an optical pressure sensor and an additional electrical, capacitive sensor in order to be able to reliably detect an object which is jammed between two parts that are moved relative to each other in a motor-driven closing mechanism, particularly an electromotive window lifter system. The optical pressure sensor encompasses a light-guiding element, a light source for injecting light into the light-guiding element, and a light sensor for detecting the extracted light. The electrical sensor encompasses an electrode that is connected to a voltage source. Both sensors are allocated to one respective evaluation unit for evaluating the respective signal.
