Title
(EN) ADVERSE WEATHER CONDITION DETECTION SYSTEM WITH LIDAR SENSOR
(FR) SYSTÈME DE DÉTECTION DE CONDITIONS MÉTÉOROLOGIQUES DÉFAVORABLES À CAPTEUR LIDAR
Abstract
(EN)
A method and apparatus detects adverse weather conditions. The method provides a system including a LIDAR sensor having a transmitting portion including a light source and illumination optics (Tx), and a receiving portion having a photodetector or photodetector array for receiving reflected light, and receiving optics (Rx). The receiving optics (Rx) is spaced from the illumination optics (Tx). The illumination optics (Tx) and the receiving optics (Rx) each define a field of view, with the field of views overlapping at a certain distance from the sensor defining a solid object sensing region. A region located outside of the solid object sensing region defines a non-overlapping region (R). The photodetector determines if a signal exists in the solid object sensing region indicative of a solid object therein. The same photodetector also determines if a signal exists in the non-overlapping region (R) indicative of an adverse weather condition affecting the vehicle.

L'invention concerne un procédé et un appareil qui détectent des conditions météorologiques défavorables. Le procédé fournit un système comprenant un capteur LIDAR possédant une partie transmission comprenant une source de lumière et une optique d'éclairage (Tx), et une partie réception comprenant un photodétecteur ou un réseau de photodétecteurs permettant de recevoir la lumière réfléchie et une optique de réception (Rx). L'optique de réception (Rx) est espacée de l'optique d'éclairage (Tx). L'optique d'éclairage (Tx) et l'optique de réception (Rx) définissent chacune un champ de vision, les champs de vision se chevauchant à une certaine distance du capteur définissant une région de détection d'objet solide. Une région située à l'extérieur de la région de détection d'objet solide définit une région sans chevauchement (R). Le photodétecteur détermine l'existence ou non d'un signal dans la région de détection d'objet solide qui indique la présence d'un objet solide à l'intérieur de cette dernière. Ledit photodétecteur détermine également l'existence ou non d'un signal dans la région sans chevauchement (R) qui indique une condition météorologique défavorable affectant le véhicule.
