Title: (DE) STEUERUNGSVERFAHREN FÜR HYBRIDSYSTEM
(EN) HYBRID SYSTEM CONTROL METHOD
(FR) PROCÉDÉ DE COMMANDE DE SYSTÈME HYBRIDE
Abstract: front page image
(EN) To reduce a torque drop caused by shift shock and time lag in a hybrid system. In a hybrid system control method of the present invention, when the gear ratio of a transmission is upshifted, the torque of a motor is instantaneously increased when half clutch control of a clutch is started, and during half clutch control, the torque of the motor is controlled to be zero or minus to compensate for an increase in a vehicle drive torque resulting from rotational inertia of an engine. The torque of the motor is increased when the clutch is completely engaged and, after this increase of the torque, is attenuated by a predetermined time constant. When the gear ratio of the transmission is downshifted, the torque of the motor is increased when half clutch control of the clutch is started, and during half clutch control, the torque of the motor is attenuated by a predetermined time constant from the torque that was increased to compensate for a drop in the vehicle drive torque resulting from rotational inertia of the engine and is smoothly connected to a torque up amount at the time of complete engagement of the clutch.
(FR) L'invention vise à réduire la chute de couple provoquée par un choc de transmission et un retard dans un système hybride. Lorsque le rapport de vitesse de transmission est amené à passer au rapport supérieur dans un procédé de commande de système hybride, un couple moteur est augmenté instantanément dès le début d'une demi-commande d'embrayage d'un embrayage, et le couple moteur commandé pour être nul ou négatif afin de compenser l'augmentation de couple d'entraînement de véhicule par l'inertie de rotation du moteur durant la demi-commande d'embrayage. Lorsque l'embrayage est complètement embrayé, le couple moteur est augmenté. Après l'augmentation du couple, le couple moteur diminue avec une constante de temps prédéterminé. Lorsqu'une rétrogradation est effectuée, le couple moteur est augmenté lors du début de la demi-commande d'embrayage et le couple moteur diminue avec une constante de temps prédéterminée à partir de l'augmentation du couple de façon à compenser la baisse du couple d'entraînement de véhicule par l'inertie de rotation du moteur, réalisant ainsi une liaison sans à-coup à une quantité de montée de couple lors d'un embrayage complet.
