Abstract
(EN)
The present invention relates to a safety system for an autonomous ground vehicle. Specifically, the present invention deals with the need to provide a safety mechanism to avoid a autonomous ground vehicle operating at too high a speed in the proximity of human operators.Accordingly the present invention provides a method for avoiding collisions between a vehicle and personnel comprising the steps of: determining the locations of personnel within a predetermined range of said vehicle; determining the proximity to said vehicle of said personnel; applying a speed profile to said vehicle for reducing the speed of the vehicle or stopping the vehicle. Accordingly the present invention also provides a safety system for a vehicle comprising: a vehicle control system; and a safety system; wherein vehicle position data and personnel position data is provided to the safety system; and if the vehicle position data and personnel position data are determined by the safety system to indicate that said vehicle is in close proximity to personnel, the safety system applies a speed profile to the vehicle control system causing the vehicle to reduce speed or stop.

La présente invention concerne un système de sécurité destiné à un véhicule terrestre autonome. L'invention concerne précisément la nécessité de fournir un mécanisme de sécurité qui permette d'éviter à un véhicule terrestre autonome de fonctionner à trop grande vitesse à proximité d'opérateurs humains. En conséquence, l'invention concerne un procédé permettant d'éviter les collisions entre un véhicule et du personnel, qui comprend : la détermination des positions du personnel dans une plage prédéfinie dudit véhicule; la détermination de la proximité avec ledit véhicule du personnel; l'application d'un profil de vitesse au véhicule afin de réduire la vitesse du véhicule ou d'arrêter le véhicule. En conséquence, l'invention concerne également un système de sécurité destiné à un véhicule qui comprend : un système de commande de véhicule; et un système de sécurité; les données de position du personnel et les données de position du véhicule sont fournies au système de sécurité; et si le système de sécurité détermine que les données de position du véhicule et les données de position du personnel indiquent que le véhicule est à proximité du personnel, le système de sécurité applique un profil de vitesse au système de commande du véhicule, ce qui amène le véhicule à réduire sa vitesse ou à s'arrêter.
