摘要： A control device for a belt-type continuously variable transmission CVT includes an engine 1, a belt-type continuously-variable transmitting mechanism 4; a forward/reverse switching mechanism 3 including a forward clutch 31 and a reverse brake 32; and a hydraulic control circuit 71 configured to control a pulley hydraulic pressure and engagement-element pressures for the forward clutch 31 and the reverse brake 32. The control device includes a selection control means for outputting a pulley hydraulic command to obtain an idle-time clamping pressure which is higher than an idle-time minimum pressure (idle-time MIN-pressure) calculated from an input torque, to the hydraulic control circuit 71, when the engine 1 is in operation during a selection of N-range. A position of an element clearance generated in the belt can be maintained even if drag torque is inputted.

摘要： A transmission controller determines whether a shift returning to low, changing a speed ratio of a continuously variable transmission to the lowest when a vehicle decelerates, is being performed or not, calculates a primary pressure measured lower limit value at which a belt begins to slip actually, based on a deceleration of the vehicle and the speed ratio of the continuously variable transmission, and sets a lower limit value of a target value of the primary pressure during the shift returning to low as the primary pressure measured lower limit value.

摘要： [Abstract] A control apparatus for a continuously variable transmission (1) that includes a belt-type continuously variable transmission mechanism (40) and friction engagement elements (32), (33) is disclosed. The control apparatus includes: operation position detection means (65) for detecting an operation position of a selection lever (50); selection control means (60b) for executing a selection control for engaging the friction engagement elements (32), (33) from a time point at which a switching from a non-travel range to a travel range is detected; determination means (60a) for determining engagement states of the friction engagement elements (32), (33); and pulley pressure control means (60c) for controlling a pulley pressure supplied to two pulleys (41), (42). The pulley pressure control means (60c) increases the pulley pressure in a case where it is determined that the friction engagement elements (32), (33) are released at a time point at which a predetermined time (T1) elapses from a start of the selection control and, thereafter, lowers the pulley pressure in a case where it is determined that the friction engagement elements (32), (33) are engaged. Thus, a belt slippage during an engagement of clutches is suppressed while a load on an oil pump is reduced.

摘要： A CVTECU (8) includes a secondary-pressure control section (8c) that controls a secondary pressure by way of a hydraulic feedback control having an integral action on the basis of a difference between a target secondary pressure and an actual secondary pressure, and a line-pressure control section (8b) that performs a same-pressure control to equalize a line pressure and the secondary pressure with each other if a predetermined start condition is satisfied. The line-pressure control section (8b) realizes a same-pressure state between the line pressure and the secondary pressure by lowering the line pressure below the target secondary pressure, and then controls the line pressure such that the actual secondary pressure is brought to the target secondary pressure by the hydraulic feedback control while maintaining the same-pressure state. The secondary-pressure control section (8c) includes a restriction section (8d) that restricts an accumulation of integral term of the integral action for a duration between a time point at which the actual secondary pressure starts to be pushed down and a time point at which the same-pressure state between the line pressure and the secondary pressure is realized.

摘要： First control unit performing first pseudo stepwise up-shift control that, in first travelling mode, increases vehicle speed while performing hold of transmission ratio and up-shift by first shifting speed and reduces engine torque upon up-shift, second control unit performing second pseudo stepwise up-shift control that, in second travelling mode, increases vehicle speed while performing hold of transmission ratio and up-shift by second shifting speed and reduces engine torque upon up-shift, and third control unit controlling change of travelling mode and switch between two pseudo stepwise up-shift controls according to control states of first and second control units, are provided. When travelling mode is changed to second travelling mode during progress of up-shift in first pseudo stepwise up-shift control, third control unit maintains first pseudo stepwise up-shift control until up-shift is completed. With this, harmonization between pseudo stepwise up-shift control and engine torque control is secured, then shift shock is suppressed.
