    Abstract: An automatic transmission for a hybrid vehicle includes a hydraulic circuit (110) having a source of pressurized fluid (112), an actuation circuit (114) that delivers pressurized fluid to actuate components of the transmission, and a cooling circuit (116) used to cool components of the transmission. The source of pressurized fluid includes a first pump (134) that is operatively driven by the internal combustion engine of the hybrid vehicle and a second pump (136) that is operatively driven by the electric motor (138). The second pump (136) acts to supply pressurized fluid to the cooling circuit (116) when the first pump (134) is operatively driven by the internal combustion engine under certain predetermined conditions.

    Abstract: [Task] A required draining capacity of an electrically-powered oil pump is reduced and a small sizing of the electrically-powered oil pump is achieved by devising how to issue a starting frictional element engagement pressure command value.
    [Means for solving the problem]
    An engine is restarted in response to an idle stop OFF command at t1 so that a gear shift control purpose hydraulic pressure is raised according to a working oil from an engine driven oil pump. An idle stop release time control of the engine is allowed according to a torque down unnecessary determination when a gear shift control purpose hydraulic pressure has reached to a set hydraulic pressure at t2. In a case where this allowance causes an engine torque Te to be raised from a torque down value toward a driving operation corresponding value by a predetermined gradient ΔTe1, a command value of a starting frictional element engagement pressure P S is set to a control maximum value (a drain port opening angle of a clutch hydraulic pressure control valve for a clutch hydraulic pressure (an engagement pressure) command value is made small as compared with that in a case of an ordinary control (is made difficult to drain)) during the idle stop control including during the idle stop release time control. Thus, when starting frictional element engagement pressure P S is controlled upon receipt of this command value, the working oil from the electrically-powered oil pump is not needed to be drained. Consequently, the electrically-powered oil pump is not needed to discharge this draining working oil and the small-sizing can be achieved.
