More Information
Summary:A method for detecting stray contacts on at least one approach or contact sensor integrated into a door handle, the handle including two electrodes whose capacitances are measured, a locking electrode, an unlocking electrode, the method includes detecting simultaneity in the crossing of the noise tolerance limits by the two capacitance value signals, and then in detecting the presence, on at least one signal, of a peak having a predetermined amplitude, the simultaneity and the peak being representative of stray contact on at least one of the electrodes.
