  • a demand as in the restart routine of Fig. 4 after the position of the clutch 3 or the transmission 6 is not necessary here, since a switching of the transmission 6 in a driving gear during the standby state by the switching prevention device 25 is generally prevented. A critical driving state in an automatic restart of the internal combustion engine 1 is prevented in this way.
  • the shutdown routines shown in FIGS. 2, 6 may comprise a further query (not shown), namely whether the charge state of the battery 19 is equal to or greater than a further, second minimum value, which is preferably selected to be greater than the first in the turn-on routines of FIG 4 and 8 described minimum value.
  • a further query not shown
  • the transition to the standby state is prevented from the outset if the charge state of the battery is so low that an automatic restart of the motor would be necessary after a short standstill.

Abstract

L'invention concerne un procédé pour faire fonctionner un véhicule automobile à moteur thermique (1), d'une boîte de vitesses manuelle (6) et d'un embrayage (3) qui relie le moteur thermique (1) à la boîte de vitesses manuelle (6). Un dispositif de commande (22) produit, en condition d'arrêt, une coupure automatique du moteur thermique (1) dans un mode d'arrêt, et condition de marche, un redémarrage automatique du moteur thermique (1). Outre un redémarrage automatique courant du moteur thermique (1) pour remettre en marche le véhicule automobile, il est prévu un redémarrage si l'état de charge d'un accumulateur d'énergie (19) pouvant être rechargé par le moteur thermique (1) tombe en dessous d'une valeur minimale pendant le mode d'arrêt. Selon l'invention, afin d'empêcher qu'un redémarrage ait lieu avec un rapport engagé et l'embrayage (3) embrayé, ce qui pourrait produire un état de marche critique pour la sécurité, le conducteur est invité au moyen d'un signal à débrayer l'embrayage ou mettre la boîte de vitesses au point mort. Selon une variante, l'invention concerne un dispositif (25) empêchant le passage de rapport, qui empêche de commuter la boîte de vitesses (6) du point mort à un rapport de marche pendant le mode d'arrêt du moteur thermique (1).
