CLUTCH CONTROL SYSTEM FOR A CONTINUOUSLY VARIABLE TRANSMISSION ABSTRACT: A clutch control system for a continuously variable transmission (25) includes a mode determination system which samples input signals including position of the neutral- drive selector (52), driver demand (45), engine speed (60), vehicle speed (58), and clutch input speed (61). From these signals the operating mode is determined and the clutch control system operating mode is set. In starting the vehicle, a minor pressure feedback loop and a major engine speed feedback loop are used. When the clutch is locked up, these control loops are not employed in regulating the vehicle operation.
