摘要： A transmission controller determines whether a shift is a kickdown, and when the shift is determined as the kickdown, the target line pressure is increased to a first target pressure corresponding to an input torque to a continuously variable transmission increased by the kickdown; the transmission controller then determines whether the line pressure has reached the first target pressure, and if determined that the line pressure has reached the first target pressure, the target line pressure is increased to a second target pressure higher than the first target pressure.

摘要： A target primary pressure and a target secondary pressure are set based on a speed ratio, a target line pressure as a target value of a line pressure is set to be a value obtained by adding an offset amount, as a positive value, to either one having a higher value out of the target primary pressure and the target secondary pressure, in at least a cross-point region as a region where an absolute value of a deviation, obtained by subtracting the target primary pressure from the target secondary pressure, is smaller than a predetermined deviation, and a primary pressure, a secondary pressure, and the line pressure are controlled to be the target primary pressure, the target secondary pressure, and the target line pressure, respectively.

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.
摘要翻译： CVTECU（8）包括：二次压控制部（8c），其基于目标二次压与实际二次压之间的差，通过具有积分作用的液压反馈控制来控制二次压;以及管路压力控制部（8b），在满足规定的起动条件的情况下，进行相同的压力控制，以使管路压力和二次压力相互一致。管路压力控制部（8b）通过将管路压力降低至目标的二次压以下来实现管路压与二次压之间的相同的压力状态，然后控制管路压以使实际的二次压达到通过液压反馈控制目标二次压力，同时保持相同的压力状态。次级压力控制部（8c）包括限制部（8d），该限制部（8d）限制积分动作的积分项的累积持续时间在实际的次级压力开始被压下的时间点和从而实现管路压力和次级压力之间的相同压力状态。

摘要： In a hydraulic control circuit including a solenoid valve, whose change responsiveness in an actual pressure with respect to a change in an instructional pressure deteriorates when the instructional pressure enters a dead band region on a lower pressure side than a dead band threshold, for adjusting a hydraulic pressure supplied to a hydraulic device operated by the hydraulic pressure based on the instructional pressure, the instructional pressure is increased in a stepwise manner to a charge pressure higher than the dead band threshold, when the instructional pressure is set in the dead band region and the instructional pressure increases within the dead band region to such an extent that a speed ratio does not change. Then, a lower limit of the instructional pressure is set to the dead band threshold, and use of the dead band region is prohibited for a certain period of time.
