Abstract
The invention relates to a method and a monitoring system for automatically actuated, in particular power-driven closing covers, for example boot lids of motor vehicles. The invention also relates to a method and a detection system for detecting the presence of objects per se. The aim of the invention is to provide solutions for the implementation of a reliable safety system. According to the invention, this is achieved by a detection system comprising a modulation unit for generating an alternating voltage, which is applied between a first output and a second output on the modulation device, a field generation structure that is coupled to one of the outputs in order to generate an extensive excitation field and a detection device comprising a detection electrode structure for detecting a field-electric effect in a detection area that extends along the electrode structure, the field generation structure and the detection electrode structure being located in the vicinity of one another and the detection electrode structure and the field generation structure being shielded from one another, in such a way that when the excitation field and the detection area are bridged by an object to be detected, a voltage event that can be classified as indicating a presence is induced in the detection electrode structure.
