Abstract

Système de commande pour véhicule automobile, ledit véhicule comprenant une pédale d’embrayage munie d’un capteur de pédale d’embrayage et une pédale d’accélérateur munie d’un capteur de pédale d’accélérateur, le capteur de pédale d’embrayage étant configuré pour émettre un signal logique d’embrayage ayant une première valeur logique si la pédale d’embrayage est actionnée, le capteur de pédale d’accélérateur étant configuré pour émettre un signal d’accélérateur dépendant de la course de la pédale, caractérisé par le fait que ledit système de commande comprend : - un comparateur relié par son entrée au capteur de pédale d’accélérateur, configuré pour émettre un signal logique d’accélérateur ayant une première valeur logique si le signal d’accélérateur reçu est supérieur à un seuil de pédale d’accélérateur, - une porte logique reliée par ses entrées au capteur de pédale d’embrayage et au comparateur, configurée pour émettre un signal logique de porte basé sur la valeur logique reçue sur ses entrées, - un moyen de logique temporisée relié par son entrée à la porte logique, configuré pour émettre un signal logique temporisé ayant une valeur logique qui correspond à la valeur logique du signal logique de porte reçu sur son entrée si la valeur logique reçue reste la même pendant une durée préétablie, et - un système d’alerte de conducteur relié à la sortie du moyen de logique temporisée, configuré pour alerter le conducteur de la nécessité de relâcher la pédale d’embrayage, après réception d’un signal logique temporisé ayant une valeur logique préétablie. Référence pour l’abrégé : Pas de figureControl system for a motor vehicle, said vehicle comprising a clutch pedal provided with a clutch pedal sensor and an accelerator pedal provided with an accelerator pedal sensor, the clutch pedal sensor being configured to output a clutch logic signal having a first logic value if the clutch pedal is actuated, the accelerator pedal sensor being configured to output an accelerator signal dependent on pedal travel, characterized by the fact that said control system comprises: - a comparator connected by its input to the accelerator pedal sensor, configured to emit an accelerator logic signal having a first logic value if the received accelerator signal is greater than a threshold of accelerator pedal, - a logic gate connected by its inputs to the clutch pedal sensor and the comparator, configured to emit a gate logic signal based on the received logic value on its inputs, - a timed logic means connected by its input to the logic gate, configured to emit a timed logic signal having a logic value which corresponds to the logic value of the gate logic signal received on its input if the logic value received remains the same for a pre-established duration, and - a driver alert system connected to the output of the timed logic means, configured to alert the driver of the need to release the clutch pedal, after receiving a logic signal timed having a pre-established logical value.
