Abstract
(DE) Die vorliegende Erfindung betrifft ein Verfahren für ein Fahrzeug (10) zur Bestimmung einer Entfernungsinformation für das Fahrzeug (10). Bei dem Verfahren wird ein Betriebszustand des Fahrzeug (10) erfasst und ein moduliertes Signal in Abhängigkeit von dem Betriebszustand erzeugt. Eine Beleuchtungseinrichtung (11) des Fahrzeugs (10) wird in Abhängigkeit von dem modulierten Signal angesteuert, um eine Szene in einer Umgebung des Fahrzeugs (10) oder innerhalb des Fahrzeugs (10) auszuleuchten. Licht (16), welches von der Beleuchtungseinrichtung (11) abgegeben wurde und von einem Objekt (17) in der Szene reflektiert wurde, wird empfangen und in Abhängigkeit von dem empfangenen Licht (16) wird ein Empfangssignal erzeugt. Die Entfernungsinformation, beispielsweise eine Entfernung zwischen dem Objekt (17) und dem Fahrzeug (10), wird in Abhängigkeit von dem modulierten Signal und dem Empfangssignal bestimmt.
(EN) The invention relates to a method for a vehicle (10) in order to determine distance information for the vehicle (10). In the method, an operating state of the vehicle (10) is detected, and a modulated signal is generated dependent on the operating state. An illuminating device (11) of the vehicle (10) is actuated dependent on the modulated signal in order to illuminate a scene in an area surrounding the vehicle (10) or a scene within the vehicle (10). Light (16) which has been emitted by the illuminating device (11) and has been reflected by an object (17) in the scene is received, and a reception signal is generated dependent on the received light (16). The distance information, for example a distance between the object (17) and the vehicle (10), is determined dependent on the modulated signal and the reception signal.
(FR) L'invention concerne un procédé pour un véhicule (10) pour déterminer une information de distance pour le véhicule (10). Dans le procédé, l'état de fonctionnement du véhicule (10) est appréhendé et un signal modulé est engendré en fonction de cet état de fonctionnement. Un dispositif d'éclairage (11) du véhicule (10) est commandé en fonction du signal modulé pour éclairer une scène dans un environnement du véhicule (10) ou à l'intérieur du véhicule (10). La lumière (16) qui a été émise par le dispositif d'éclairage (11) et qui a été réfléchie par un objet (17) dans la scène est captée, et un signal de réception est engendré en fonction de la lumière captée (16). L'information de distance, par exemple la distance entre l'objet (17) et le véhicule (10), est déterminée en fonction du signal modulé et du signal reçu.
