Abstract
(DE) Die Erfindung betrifft ein Verfahren zur Steuerung einer Brennkraftmaschine, wobei die Brennkraftmaschine mit einer Vorrichtung zur Änderung einer Ventilsteuerung ausgestattet ist. Um eine Änderung der Ventilsteuerung nur dann stattfinden zu lassen, wenn diese für den Betrieb der Brennkraftmaschine erforderlich ist, wird vorgeschlagen, ein der Brennkraftmaschine nachgeschaltetes Getriebe dahingehend zu überwachen, ob im Getriebe ein Schaltvorgang stattfindet. Wird ein solcher Schaltvorgang erkannt, so wird eine Änderung der Ventilsteuerung unterdrückt.
(EN) The invention relates to a method for control of an internal combustion engine, whereby the internal combustion engine is equipped with a means of variable valve control. The aim of the invention is to only permit a change in valve control, when necessary for the operation of the internal combustion engine. Said aim is achieved, whereby a gearbox, arranged in series with the engine, is monitored for a gear change process. When such a gear change process is occurring, the change in valve control is inhibited.
(FR) L'invention concerne un procédé de commande d'un moteur à combustion interne, ce moteur à combustion interne étant pourvu d'un dispositif de variation d'une commande de soupapes. Pour autoriser une variation de la commande de soupapes uniquement lorsque celle-ci est nécessaire au fonctionnement du moteur à combustion interne, on vérifie en continu selon l'invention si un processus de changement de vitesse a lieu dans une boîte de vitesses placée en aval du moteur à combustion interne. Si un tel processus de changement de vitesses est détecté, une variation de la commande de soupapes est empêchée.
