  • an authorization proof key circuit can be done so that a certain signal transfer is handled in the context of a preprocessing, and a decisive for the change of the locking state signal transfer in the context of an introduced by the signal change pattern second dialogue phase takes place.

  • This signal (fl) is fed to an input of an exclusive OR (XOR).
  • XOR exclusive OR
  • a second oscillator is constructed whose frequency-determining element consists of a resistor and a small capacitor (approximately 1 pF). The output of this oscillator should also be digital and lead to the second input of the XOR (f2).
  • a low-pass filter connected, for example, has a transmittance of about 10 kHz (0-10 kHz).
  • the capacitor Cl of the second oscillator is connected at one end to ground, connected at the other with the frequency-determining resistor Rl. At this point, the sensor element of the handle is turned on. When an additional capacitance, for example a human hand, is brought into the vicinity of this sensor, the total capacity of the oscillator 2 increases and its frequency decreases.
  • Oscillator 2 is set to 101 kHz, so that at the output of the voltage applied to the XOR low pass resulting from the mixture low frequency of 1 kHz can be measured.
  • the oscillator 2 When approaching a hand to the sensor element, an additional capacitance Cx, the oscillator 2 causes to lower its frequency. If this reaches 100 kHz, then the difference between the oscillator 1 is equal to zero, which can also be tapped off as a zero level at the low pass. This point should be set so that it happens just when the hand is close enough to the grip to be able to enclose it. If the grip is now further enclosed, the capacitance of oscillator 2 again increases, so that the frequency 2 2 is lower than that of the stable oscillator 1, for example 98 kHz. This has the consequence that at the output of the low-pass a frequency change from zero to 2 kHz is observed.
  • the approach of the hand to a handle initially produces a mixing frequency of 1 kHz to zero and then from zero to over 2 kHz. Only when an activated logic detects such a frequency change, a safe opening intention can be determined.
  • the frequency 2 2 changes so much due to the now high capacitance Cx on the oscillator 2 that a very high mixing frequency arises.
  • the sensor element can easily distinguish between approach, enclosure and touch of a handle safely.
  • the slightly higher frequency of the oscillator 2 (here, for example, 1 kHz) in its initial position can be used on the one hand to constantly detect the correct operation of the sensor (monitor) and on the other hand it can compensate for ambient drift (temperature, humidity, etc be made by a control circuit ensures that with little deviation, the frequency is always adjusted.
  • the circuit of Figure 1 is connected to a metallic door handle. A hand is then brought in the vicinity of the door handle, as if you want to enclose this below.
  • the output frequency on the low pass is now set to zero.
  • the fundamental frequency at the output of the low-pass filter can be measured.
  • this frequency drops to zero and rises again when the handle is enclosed.
  • An intention to open is recognizable by the typical time change of the frequency occurring when the hand approaches, before the door handle is actually touched.

Abstract

L'invention concerne un circuit électrique permettant de générer ou de recevoir un signal de sortie ou un état de commutation déterminant l'état de verrouillage effectif du système portière, notamment du système portière d'un véhicule automobile. L'invention vise à créer un circuit délivrant un signal qui détermine l'état de verrouillage d'un système portière et dont la génération prend plus en considération l'intention de l'utilisateur ou la situation du moment. A cet effet, on utilise, selon un premier aspect de l'invention, un circuit électrique destiné à la génération d'un signal de sortie ou d'un état de commutation déterminant le déroulement de la détermination de l'état de verrouillage d'un système portière. Ce circuit comprend des composants système qui sont montés sur la portière et renferment des moyens permettant la détection d'interactions électriques en relation avec une action, notamment le déplacement d'un utilisateur dans la zone environnante du système portière, notamment à proximité de la portière. Et ce circuit permet d'analyser les modifications de chaque interaction, notamment en ce qui concerne certains motifs de modification de signaux temporels, et l'éventuelle présence de certains motifs de modification de signaux temporels lors du traitement électronique ultérieur des signaux, est prise en considération pour déterminer l'état de verrouillage.
