ABSTRACT:
A control system for a continuously variable transmission for a vehicle, includes a hydraulically operable driver pulley, a follower pulley, a transmission V-belt tensioned between the driver and follower pulleys, and means, including a shift actuator and a shift control valve, for hydraulically controlling a reduction ratio between the driver and follower pulleys. In order to provide inproved shift response of the transmission upon depressing an accelerator pedal after a quick brake state of a vehicle where the vehicle wheels are locked, a position of a movable conical disk of the driver pulley which it would assume after initiation of the quick brake state is determined by arithmetic operation, and a shift actuator is driven toward a position thereof corresponding to the position assumed by the driver pulley so that the V-belt is tensioned between the driver and follower pulleys and conditioned to be ready for torque transmission.
