English Abstract

The present invention relates to a system and method for turning off a vehicle when in an idle state. The system comprises a stationary state detector for detecting a stationary state of the vehicle and a timer for measuring a period during which a stationary state is detected. In addition to this, the system further comprises a presence sensor for sensing the presence of a driver in the vehicle and an engine cutoff for turning off the fuel engine. Moreover, the system comprises a controller for processing an input from the stationary state detector, an input from the timer and an input from the presence sensor. The controller is adapted to activate the engine cutoff when the stationary state is detected for a period of time that is greater than a period threshold and when the presence sensor senses that the driver is present.


French Abstract

La présente invention concerne un système et une méthode permettant darrêter un véhicule lorsquil est en état au ralenti. Le système comprend un détecteur détat stationnaire permettant de détecter un état stationnaire du véhicule et un chronomètre permettant de mesurer une période pendant laquelle un état stationnaire est détecté. De plus, le système comprend un capteur de présence qui capte la présence dun conducteur dans le véhicule et un intercepteur de moteur permettant darrêter le moteur à essence. En outre, le système comprend un contrôleur qui traite des données dentrée provenant du détecteur détat stationnaire, des données provenant du chronomètre et des données provenant du capteur de présence. Le contrôleur est adapté pour activer lintercepteur de moteur lorsque létat stationnaire est détecté pendant une période plus longue quune période seuil et lorsque le capteur de présence détecte que le conducteur est présent.
