Title
(EN) COMPUTER-IMPLEMENTED METHOD FOR MAINTAINING A DRIVER'S PERCEIVED TRUST LEVEL IN AN AT LEAST PARTIALLY AUTOMATED VEHICULE
(FR) PROCÉDÉ MIS EN ŒUVRE PAR ORDINATEUR POUR MAINTENIR LE NIVEAU DE CONFIANCE PERÇU PAR UN CONDUCTEUR DANS UN VÉHICULE AU MOINS PARTIELLEMENT AUTOMATISÉ
Abstract
(EN)
The present invention concerns a computer-implemented method for maintaining a driver's perceived trust level in an at least partially automated vehicle (1), comprising the steps of monitoring one or more parameters concerning the driver (6), the vehicle (1) and/or a surrounding environment; predicting, based on the one or more parameters, a decrease in the perceived trust level; and carrying out one or more countermeasures to compensate for the predicted decrease in the perceived trust level.
(FR)
La présente invention concerne un procédé mis en œuvre par ordinateur pour maintenir le niveau de confiance perçu par un conducteur dans un véhicule au moins partiellement automatisé (1), comprenant les étapes consistant à surveiller un ou plusieurs paramètres concernant le conducteur (6), le véhicule (1) et/ou un environnement ambiant ; prédire, sur la base du ou des paramètres, une diminution du niveau de confiance perçu ; et réaliser une ou de plusieurs contre-mesures pour compenser la diminution prédite du niveau de confiance perçu.
