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： 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.

摘要： A first target secondary pulley pressure (Psteng) is calculated based on an output torque (Teng) of an engine (5), and then an offset value (Psteng+PO) is calculated by adding a predetermined offset (PO) to the (Psteng). The (Psteng) is outputted as a target secondary pulley pressure (Ps(n)) when a target secondary pulley pressure (Ps(n-1)) in a previous control cycle is less than or equal to the (Psteng); the offset value (Psteng+PO) is outputted as the (Ps(n)) when the (Ps(n-1)) is greater than or equal to the offset value (Psteng+PO); and otherwise, the (Ps(n-1)) is outputted as the (Ps(n)) (steps S2 to S6). Accordingly, an oscillation in the target secondary pulley pressure (Ps(n)) can be suppressed.

摘要： In a control apparatus for a continuously variable transmission with a sub transmission, a primary solenoid valve (118) installed at an oil passage midway position from a mechanical oil pump (10) to a primary pulley (21) and configured to control a hydraulic pressure to the primary pulley (21) and a transmission controller (12) which outputs a primary current command value (PriSOL/I*) to primary solenoid valve (118) are provided. The transmission controller (12) outputs primary current command value (PriSOL/I*) which previously closes an oil passage from the mechanical oil pump (10) to the primary pulley (21) to the primary solenoid valve (118) before a rise in engine revolution number (Ne) due to at least a re-start of the engine, when a coast stop control/an idle stop control is carried out.
