  • control unit 50 continues idling the engine 60 until the voltage of the capacitor C becomes equal to or higher than the target voltage (see S22 and S23 in FIG. 3).
  • the process returns to the step S11 again (see the right arrow of S22 in FIG. 3), and the engine 60 is temporarily stopped and idling stopped (see S11 in FIG. 3).
  • the voltage of the capacitor C becomes less than the startable voltage both while the motorcycle is temporarily stopped and the engine 60 is idling and while the engine 60 is idling stopped. It can be prevented that the engine 60 cannot be started. Further, the engine 60 can be idling stopped under appropriate conditions, so that fuel efficiency can be improved and an environmental load can be reduced.

Abstract

L'invention concerne un circuit (100) de commande du moteur d'un véhicule à deux roues pouvant être démarré en utilisant un kick de démarrage (65). Ledit circuit (100) de commande du moteur est muni des éléments suivants : un circuit de détection de tension (20) qui détecte la tension traversant un condensateur (C) ; une unité de commande (50) qui, sur la base de la tension du condensateur (C) détectée par le circuit de détection de tension (20), commande l'alimentation d'un moteur cellulaire (46) et l'alimentation du condensateur (C) en énergie électrique générée par un générateur (41) ; et un circuit de commande de charge (30) qui commande l'énergie électrique alimentant une charge (31). Si la tension traversant le condensateur (C) est inférieure à une tension permettant le démarrage lorsqu'un commutateur d'allumage (70) est mis en circuit, le circuit de commande de charge (30) bloque l'alimentation électrique de la charge (31) et l'unité de commande (50) empêche le moteur cellulaire (46) de démarrer le moteur (60). Mais si la tension traversant le condensateur (C) est supérieure ou égale à la tension permettant le démarrage lorsque le commutateur d'allumage (70) est mis en circuit, l'unité de commande (50) permet au moteur cellulaire (46) de démarrer le moteur (60).
