Abstract

Système de déverrouillage ou d'ouverture d'ouvrant(s) de véhicule, notamment automobile, de type « mains libres », comportant un dispositif de détection de présence, ainsi que des moyens pour l'émission d'un signal d'interrogation qui sont réveillés lorsque ledit dispositif détecte la présence d'un individu, caractérisé en ce que ledit dispositif de détection de présence comporte des moyens d'émission d'un signal ultrasonore ou radioélectrique, des moyens pour la détection d'un signal d'écho et des moyens pour le traitement du signal ainsi détecté afin d'en déduire une information sur la présence d'un obstacle.
The vehicle doors unlocking system includes a device (1) for detection of the presence of a person near to the vehicle. In response to this detection a circuit (2) producing an interrogation signal is activated. The interrogation signal operates either by an ultrasound signal or a radio signal to interrogate a transponder (3) which is carried by the owner of the vehicle. The unlocking system for opening vehicle doors includes a device (1) for detection of the presence of a person near to the vehicle. In response to this detection a circuit (2) producing an interrogation signal is activated. The interrogation signal operates either by an ultrasound signal or a radio signal to interrogate a transponder (3) which is carried by the owner of the vehicle. If the interrogation of the transponder produces a valid response, then the vehicle is automatically unlocked. The system is active only when the vehicle is stopped. The system for the detection of the presence of a person or object adjacent to the vehicle may also be used as an aide to parking.
