Method for detection of contact of chassis part with another chassis part of vehicle and for detection of approach on chassis part by person, involves determining change of capacitance of dipole, which consists of two chassis parts

摘要

The method involves ascertaining or determining the change of the capacitance of a dipole (1), which consists of a chassis part (2.1) and another chassis part (2.2) that are electrically insulated from each other. The capacitance is determined by measuring a value of an impedance of the dipole at a predetermined frequency, measuring a detuning of an oscillator with the dipole or by determining a charging or discharging constants of the resistance capacitor element with dipole. An independent claim is also included for a device for detection of a contact of chassis part with another chassis part of a vehicle and for detection of an approach on the chassis part by a person.
