Verfahren zur Steuerung der Kupplungsbetätigung für Fahrzeuge.

摘要

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 a driver's intention of acceleration or deceleration: and controlling the 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. A method of determining clutch engagement completion in a continuously variable speed transmission comprises setting a lower limit of an expected clutch engagement completion vehicle speed corresponding to an accelerator opening representing an 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 is above the lower limit and the opening of said clutch valve is below a given opening, and permitting subsequent speed ratio control.
