Abstract

La présente invention a pour objet une unité de commande électronique (1) comportant une diode (7) de protection contre des inversions de polarité, caractérisée en ce qu'elle comporte un moyen (8) permettant de court-circuiter ladite diode (7) de protection. Elle concerne encore un procédé de gestion de l'alimentation d'une unité de commande électronique (1) pendant la phase de démarrage du moteur d'un véhicule automobile muni d'une batterie, caractérisé en ce que : • on détecte une commande de démarrage moteur indiquant le début de la phase de démarrage moteur ou une tension de batterie inférieure à une tension de seuil prédéterminée ; • on court-circuite la diode (7) de protection ; • on maintient ce court-circuit tant que le démarrage effectif du moteur n'est pas acquitté ou tant que la tension de la batterie n'a pas atteint un seuil prédéterminé ; • on rétablit la connexion de la diode (7) de protection lorsque le démarrage effectif du moteur est acquitté.The present invention relates to an electronic control unit (1) comprising a diode (7) for protection against reverse polarity, characterized in that it comprises a means (8) for short-circuiting said diode (7) protection. It also relates to a method for managing the power supply of an electronic control unit (1) during the starting phase of the engine of a motor vehicle fitted with a battery, characterized in that: • a control command is detected engine start indicating the start of the engine start phase or a battery voltage lower than a predetermined threshold voltage; • the protection diode (7) is short-circuited; • this short circuit is maintained as long as the effective start of the engine is not acknowledged or as long as the battery voltage has not reached a predetermined threshold; • the connection of the protective diode (7) is restored when the actual start of the motor is acknowledged.
