摘要： At vehicle stop judgment time t1, a first engine automatic-stop control permission judgment, based on idle stop permission conditions by which an instant permission judgment can be possible, is carried out. If a result of the first engine automatic-stop control permission judgment at time t1 is “permitted”, the second engine automatic-stop control permission judgment, based on an idle stop permission condition which requires a certain time for the judgment, is initiated, and an electric oil pump ON (drive) command (the test drive command) is issued. At time t2 at which an actual drive of the electric oil pump in response to the test drive command is detected, it is judged that a failure of an electric system of the electric oil pump and a foreign matter-biting failure of the electric oil pump do not occur, then a failure judgment of the electric oil pump becomes “normal”. This judgment is completed before time t3 at which the second engine automatic-stop control permission judgment ends, and both of “permitted” of a result of the second engine automatic-stop control permission judgment and “normal” of the failure judgment of the electric oil pump, an idle stop ON command is not outputted.

摘要： 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 Ps is set to a control maximum value during the idle stop control including during the idle stop release time control.

摘要： 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 PS 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 PS 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.

摘要： A continuously variable transmission (4) comprises an endless torque transmission member (13) looped around a pair of pulleys (11, 12). At least one of the pulleys changes a winding radius of the endless torque transmission member (13) in accordance with an applied pulley thrust. A controller (22) estimates a stretch amount of the endless torque transmission member (13) based on an operating state of the continuously variable transmission (4), sets a slip limit thrust based on the stretch amount, and controls the pulley thrusts based on the slip limit thrust. In this manner, appropriate pulley thrust control in accordance with whether or not the endless torque transmission member (13) stretches is realized.

摘要： A continuously variable transmission (4) shifts between a pair of pulleys (11, 12) via an endless torque transmission member (13) mounted on the pair of pulleys (11, 12). A controller (22) executes a feedback-control so that a real speed ratio between the pair of pulleys (11, 12) follows a target speed ratio (S6, S46). The controller (22) determines whether or not a elongation-affected shift condition, under which it is impossible for the real speed ratio to reach the target speed ratio depending on whether or not the endless torque transmission member (13) is elongated, holds (S2, S3, S12, S13), and limits a speed ratio feedback control when the elongation-affected shift condition holds (S4, S24, S34).

摘要： The transmission controller changes the gear position of the subtransmission mechanism and varies the speed ratio of the variator in an opposite direction to a speed ratio variation direction of the subtransmission mechanism when the actual through speed ratio passes a predetermined mode switch line. When the improvement in the shift response of the continuously variable transmission is determined to be required and the actual through speed ratio passes the mode switch line from a Low side to the High side, the transmission controller increases a shift speed of the subtransmission mechanism compared with a normal coordinated shift.

摘要： After an engine (1) has started, a controller (6) starts determining whether lockup should be prohibited or permitted based on the cooling water temperature of an engine (1) or the oil temperature of a transmission (2). Once it has been determined that lockup should be permitted, the controller (6) stops determining whether lockup should be prohibited or permitted until the next time the engine (1) is started. In this way, once the conditions for determining that lockup should be permitted hold, lockup prohibition or permission based on the engine cooling water temperature or transmission oil temperature is no longer determined, so repeat engaging and disengaging of the lockup clutch (5) due to fluctuations of engine cooling water temperature or transmission oil temperature, is prevented.
