Title
(EN) SYSTEMS AND METHODS FOR BRAKING A VEHICLE BASED ON A DETECTED OBJECT
(FR) SYSTÈMES ET PROCÉDÉS DE FREINAGE D'UN VÉHICULE SUR LA BASE D'UN OBJET DÉTECTÉ
Abstract
(EN)
Systems and methods are provided for detecting an object and causing a vehicle to brake based on the detection. In one implementation, an object detecting and braking system for a vehicle includes at least one image capture device configured to acquire a plurality of images of an area including an object in front of the vehicle. The system includes at least one processing device programmed to perform a first image analysis to determine a first estimated time-to-collision of the vehicle with the object, and to perform a second image analysis to determine a second estimated time-to-collision of the vehicle with the object. The processing device is also programmed to calculate a difference between the first estimated time-to-collision and the second estimated time-to-collision, to determine that the difference does not exceed a predetermined threshold, and to cause the vehicle to brake based on the determination that the difference does not exceed the predetermined threshold.

La présente invention concerne des systèmes et des procédés permettant de détecter un objet et d'amener un véhicule à freiner en fonction de la détection. Dans un mode de réalisation, un système de détection d'objet et de freinage pour un véhicule comprend au moins un dispositif de capture d'image configuré pour acquérir une pluralité d'images d'une zone comprenant un objet à l'avant du véhicule. Le système comprend au moins un dispositif de traitement programmé pour effectuer une première analyse d'image pour déterminer un premier temps estimé avant collision du véhicule avec l'objet, et pour effectuer une seconde analyse d'image pour déterminer un second temps estimé avant collision du véhicule avec l'objet. Le dispositif de traitement est également programmé pour calculer une différence entre le premier temps estimé avant collision et la seconde estimation de temps estimé avant collision, pour déterminer que la différence ne dépasse pas un seuil prédéterminé, et pour amener le véhicule à freiner en fonction de la détermination selon laquelle la différence ne dépasse pas le seuil prédéterminé.
