Cooperative control system for prime mover and continuously variable transmission of vehicle

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 said continuously variable transmission is lowered on the basis of a decision of the slip in the continuously variable transmission, comprising:

• clamping pressure/input torque sequential control means for raising an actual pressure of said clamping pressure at or after a deciding instant of said slip convergence, and for executing a control to complete a restoration of an actual torque of said lowered input torque afterward.
