Abstract
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 MG. 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 MGand MGexecute 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.
