摘要： PROBLEM TO BE SOLVED: To provide a control device for an automobile continuously variable transmission, capable of reducing overshooting of a gear ratio, even when increasing the shifting speed during gear-ratio shifting. SOLUTION: The control device comprises an actual pulley ratio detecting means 102, an arrival target pulley ratio setting means 100, and a control means 103 for controlling the position of a step motor 27. The control means 103 consists of a normal control part 103b for feedback-controlling the step motor 27 to be operated at a first speed; a high-speed control part 103a for open-loop controlling it to be operated, at a second speed higher than the first speed, based on the arrival target pulley ratio; a determining part 101 for determining whether high speed operation is required; and a change-over part P1 for selecting control by the normal control part 103b in a normal condition and changing over it into control by the high speed control part 103a, when change-over starting conditions, including the determination that the high speed operation is required, are established.

摘要： PROBLEM TO BE SOLVED: To prevent hunting of a transmission ratio caused by abrupt decrease of actual line pressure during a line pressure feedback control. SOLUTION: In a line pressure controller for a belt type continuously variable transmission of the invention, when a feedback control of line pressure is performed so that the line pressure becomes equal to target line pressure of not less than larger pressure out of hydraulic pressure supplied to a primary pulley and hydraulic pressure supplied to a secondary pulley (S1), and when it is determined the divergence between the actual line pressure and the target line pressure since the target line pressure becomes first low pressure (S6), the target line pressure is limited not to be below a lower limit value (S7).

摘要： PROBLEM TO BE SOLVED: To provide a control device for an automobile continuously variable transmission, capable of preventing slippage of a belt by increasing actual secondary pressure even when increasing a shifting speed at shifting. SOLUTION: The control device comprises a secondary pressure control valve 24 for controlling the thrust of both pulleys 2, 3 on the belt 4, an orifice mounted in an oil path between the secondary pulley 3 and the secondary pressure control valve 24, a hydraulic pressure sensor 15 provided on the side of the secondary pressure control valve 24 beyond the orifice, a target secondary pressure setting means 12c, and a control means 12 for feedback-controlling the secondary pressure control valve, based on the target secondary pressure and the actual secondary pressure. The control means 12 has an operation change-over part P1 for performing shifting operation at a higher speed than normally. The target secondary pressure setting means 12c corrects the target secondary pressure to be increased, when correcting conditions including the change-over of the shifting operation to be performed at a higher speed are established.
