Pulley actuating hydraulic pressure control for continuously variable transmission |
摘要 |
According to a hydraulic pressure control system for a continuously variable transmission embodying the present invention, a hydraulic fluid pressure supplied to pulleys is increased temporarily during a transient period where the transmission upshifts from a reduction ratio to a smaller reduction ratio as a result of a predetermined movement of a manual selector valve. The level of the hydraulic fluid pressure is allowed to return to the previous low level after the transient period.
