摘要： In a speed ratio control device for a belt continuously variable transmission according to this invention, when a speed ratio is subjected to feedback control on the basis of a difference between an actual speed ratio and a target speed ratio, pressure supplied to a primary pulley is corrected through feedforward (S17, S18) in order to suppress variation in the groove width of the primary pulley caused by a rapid variation in an input torque into the primary pulley (S17) while traveling in a fixed speed ratio mode (S14) in which the target speed ratio is held at a fixed value.

摘要： In a line pressure control apparatus of a belt-drive CVT, a shift is achieved by varying V- groove widths of primary and secondary pulleys by a differential pressure between primary and secondary pulley pressures, originating from line pressure. The differential pressure is created by bringing a shift actuator, such as a step motor, into a control position corresponding to a target transmission ratio. The target transmission ratio is calculated based on a theoretical transmission ratio based on engine-and-vehicle operating conditions, taking account of a hardware response delay and a disturbance. The target transmission ratio is converted into a reference-model operative position, corresponding to a reference-model number-of-steps of the shift actuator. An actual transmission ratio is converted into an actual-transmission-ratio related operative position. Line pressure is corrected in a manner so as to reduce the positional deviation between the reference-model operative position and the actual-transmission-ratio related operative position.

摘要： A positional deviation ERRstep of a step motor 27 is calculated on the basis of a reference model step StepMdl, an actual speed ratio-corresponding step Bstep, and an added value obtained by adding together a target deviation GTstep, calculated in accordance with a transmission input torque Ti, and a starting learned value Gstep. When the transmission input torque Ti is large, the target deviation GTstep is increased in accordance with the transmission input torque Ti. A line pressure PL is then controlled on the basis of the positional deviation ERRstep obtained as a result.

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.
