Abstract

Un dispositif de commande de passage de rapports (1) inclut un moteur électrique (7) qui génère une puissance électrique en utilisant un couple régénératif (Tr) d'une roue motrice (12), ou un couple de moteur thermique (5) généré par un moteur thermique (5), et génère un couple de fonctionnement électrique (Tp) pour la roue motrice (12) en utilisant la puissance électrique d'une batterie rechargeable; une transmission (11) qui transmet le couple de moteur thermique (5) à la roue motrice (12) ; un embrayage (9) qui transmet et interrompt le couple de moteur thermique (5) ; et une unité de commande qui commande le couple de fonctionnement électrique (Tp) du moteur électrique (7), le désenclenchement et l'enclenchement de l'embrayage (9), et le passage de rapports de la transmission (11). Lorsque l'unité de commande permet à la transmission (11) de changer de vitesse alors que le moteur électrique (7) réalise la génération de puissance, l'unité de commande diminue le couple du moteur électrique (7), commence le désenclenchement de l'embrayage (9), et après cela commence le passage de rapports de la transmission (11).A gear change control device (1) includes an electric motor (7) which generates electric power by using regenerative torque (Tr) of a drive wheel (12), or heat engine torque (5) generated. by a heat engine (5), and generates an electrical operating torque (Tp) for the drive wheel (12) using the electrical power of a rechargeable battery; a transmission (11) which transmits the torque of the heat engine (5) to the driving wheel (12); a clutch (9) which transmits and interrupts the torque of the heat engine (5); and a control unit which controls the electric operating torque (Tp) of the electric motor (7), the disengagement and engagement of the clutch (9), and the shifting of the transmission (11). When the control unit allows the transmission (11) to change speed while the electric motor (7) is generating power, the control unit decreases the torque of the electric motor (7), starts the disengagement of the clutch (9), and after that begins the gear change of the transmission (11).
