Abstract
A cooperative control system for a prime mover and a continuously variable transmission of a vehicle, in which the continuously variable transmission is connected to an output side of the prime mover for generating a driving force for running, and in which a clamping pressure to set a torque capacity of the continuously variable transmission is raised and an input torque to the continuously variable transmission is lowered on the basis of a decision of the slip in the continuously variable transmission. A clamping pressure/input torque sequential control raises an actual pressure of the clamping pressure at or after a deciding instant of the slip convergence, and executes a control to complete a restoration of an actual torque of the lowered input torque afterward.
