Abstract
A method of controlling clutch operation, for a vehicle having a transmission and clutch means comprises setting a reference capacity of said clutch means corresponding to a parameter representing vehicle speed and an accelerator opening representing the driver's intention of acceleration or deceleration: and controlling said degree of the engine power transmitted to the wheels by adjusting the capacity of said clutch means so as to coincide with said reference capacity. An embodiment of the method includes a method of determining clutch engagement completion in continuously variable speed transmission comprises setting a lower limit of an expected clutch engagement completion vehicle speed corresponding to an accelerator opening representing operator's intention of acceleration and deceleration, determining, in vehicle start, that said clutch valve is closed to engage the clutch completely when it is detected that vehicle speed has been below the lower limit and the opening of said clutch valve has been below a given opening, and permitting successive speed ratio control.
