Abstract
An engine is restarted in response to an idle stop OFF command at tso 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 t. 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 ΔTe, a command value of a starting frictional element engagement pressure Pis set to a control maximum value during the idle stop control including during the idle stop release time control.
