ABSTRACT:
A hydraulic continuously variable speed transmission includes means for detecting a speed reduction ratio of said continuously variable speed transmission, means for detecting an accelerator opening, and means for detecting vehicle speed. During running, when the means for detecting the accelerator opening detects that the accelerator opening has been fully closed, the means for detecting speed the reduction ratio detects the speed reduction ratio at the moment, and then an operation initiating vehicle speed of said clutch valve is determined based on the detected speed reduction ratio, and when the vehicle speed detected by the means for detecting vehicle speed is reduced to the operation initiating vehicle speed, the clutch valve starts to open.
