Abstract:
A power transmitting apparatus includes a clutch that operates based on pressure of a fed fluid to adjust a mode of power transmission of an engine or/and a motor/generator on a power transmission route, a first driving pump that feeds the fluid to the clutch by being driven in accordance with rotation of the motor/generator, and a second driving pump that feeds the fluid to the clutch by being driven in accordance with electric power, wherein a first engagement unit and a second engagement unit can be caused to engage rapidly or slowly by selecting one of the first driving pump and the second driving pump as a source of the fluid, and when a drive request of the clutch is present and a rotation speed of the motor/generator is lower than a predetermined rotation speed, the first engagement unit and the second engagement unit are caused to engage rapidly by feeding the fluid from the second driving pump.
