Abstract:
(EN) A control device for a power transmission device for a four-wheel drive vehicle. The device has an increased degree of freedom of driving force distribution to provide the vehicle with favorable distribution of driving force. Driving force distribution change means (64) partially engages (slipping engagement) a clutch device (41) to change both a driving force outputted from a second driving force source (13) and the capacity of engagement (torque capacity) of the clutch device (41), and this changes the distribution of driving force between an output shaft (14) for front wheels and an output shaft (16) for rear wheels. Partially engaging the clutch device (41) enables a part of a driving force (T2) from the second driving force source (13) to be transmitted to the output shaft (14) for front wheels. Further, changing the driving force (T2) outputted from the second driving force source (13) increases the degree of freedom of driving force distribution between the front wheels (18) and the rear wheels (20).
(FR) La présente invention se rapporte à un dispositif de commande pour un dispositif de transmission de puissance destiné à un véhicule à quatre roues motrices. Le dispositif a un degré augmenté de liberté de distribution de force d’entraînement pour donner au véhicule une distribution favorable de force d’entraînement. Des moyens de changement de distribution de force d’entraînement (64) mettent partiellement en prise (prise coulissante) un dispositif d’embrayage (41) pour modifier à la fois une force d’entraînement sortie d’une seconde source de force d’entraînement (13) et la capacité de prise (capacité de couple) du dispositif d’embrayage (41), et cela modifie la distribution de force d’entraînement entre un arbre de sortie (14) destiné aux roues avant et un arbre de sortie (16) destiné aux roues arrière. La prise partielle du dispositif d’embrayage (41) permet à une partie d’une force d’entraînement (T2) provenant de la seconde source de force d’entraînement (13) d’être transmise à l’arbre de sortie (14) destiné aux roues avant. En outre, la modification de la force d’entraînement (T2) sortie de la seconde source de force d’entraînement (13) augmente le degré de liberté de distribution de force d’entraînement entre les roues avant (18) et les roues arrière (20).
(JA)  四輪駆動車両用動力伝達装置において、駆動力配分の自由度をさらに高め、好適な駆動力配分を得ることができる四輪駆動車両用動力伝達装置の制御装置を提供する。 駆動力配分変更手段64は、第2の駆動力源13から出力される駆動力およびクラッチ装置41の係合容量(トルク容量)を変化させることにより、前輪用出力軸14および後輪用出力軸16の駆動力配分を変更するため、クラッチ装置41を半係合(スリップ係合)させることで、第2の駆動源13からの駆動力T2の一部を前輪用出力軸14に伝達することができ、また、第2の駆動源13から出力される駆動力T2を変化させることで、前輪18および後輪20への駆動力配分の自由度を高めることができる。
