Abstract
(EN)
This object aims to provide a controller of a power transmission device for a vehicle, which includes an electric differential section in which loss of acceleration can be suppressed during acceleration of the vehicle. This controller performs inertia torque compensation control, in which a compensation torque (ΔTm1) for reducing the inertia torque (Tit) that is generated in a first motor (M1) due to changes in the rotational speed of a second motor (M2) during acceleration of a vehicle, thereby suppressing reduction in power outputted from the second motor (M2) and keeping a sufficient acceleration performance. In conclusion, a controller of the power transmission devices (10, 30) for a vehicle having electric differential sections (18, 34) capable of suppressing loss of acceleration controlling of the power transmission devices (10, 30) for a vehicle having electric differential sections (18, 34) during acceleration of a vehicle can be provided.

L'invention concerne un module de commande d'un dispositif de transmission de puissance pour un véhicule, le module de commande comprenant une partie différentielle électrique permettant de supprimer la perte d'accélération au cours d'une accélération du véhicule. Le module de commande assure une commande de compensation de couple d'inertie consistant à générer un couple de compensation (ΔTm1) destiné à réduire le couple d'inertie (Tit) généré dans un premier moteur (M1) du fait des variations de la vitesse de rotation d'un second moteur (M2) au cours de l'accélération du véhicule, de manière à éviter une réduction de la puissance fournie par le second moteur (M2) et à maintenir les performances d'accélération à un niveau acceptable. Le module de commande de l'invention permet donc de commander les dispositifs de transmission de puissance (10, 30) d'un véhicule grâce à des parties différentielles électriques (18, 34) susceptibles de supprimer la perte d'accélération au cours dune accélération du véhicule.
