    摘要： In a hydraulic controller of driving force distribution device, including: a hydraulic circuit composed of an oil pump for supplying hydraulic fluid to a piston chamber of a clutch (or a driving force distribution device), an opening and closing valve installed in an oil passage between a check valve and the piston chamber, and an accumulator communicating to the piston chamber; control is performed so that the piston chamber reaches a target hydraulic pressure based on the 1st characteristic by closing the opening and closing valve and driving the oil pump at the time of pressurizing the piston chamber; and control is performed so that the piston chamber reaches a target hydraulic pressure based on the 2nd characteristic by prohibiting the driving of the oil pump along with opening the opening and closing valve.

    摘要： A control device for a power transmitting device for four-wheel drive hybrid-vehicle is provided capable of preventing the occurrence of negative torque resulting from power generation control of a second electric motor MG2. Drive-force control executes a control such that rear-wheel output torque Tpr of rear wheels falls in a positive torque when first and second electric motors MG1 and MG2execute power generation controls, thereby preventing torques of front and rear wheels from orienting in different directions. Accordingly, the front and rear wheels have torques oriented in the same direction, thereby favorably preventing discomfort feeling during a vehicle running.
