A shift control system for a continuously variable transmission, in which a road load on a vehicle is detected, the lower limit speed is set according to the detected road load, in which a target input speed, as set according to the running state of a vehicle, is restricted with the set lower limit speed, and in which the gear ratio of the continuously variable transmission is controlled so that the actual input speed may be equal to the target input speed restricted. The target input speed is restricted after the actual input speed is more than the lower limit value, when the road load is light, and said target input speed is restricted irrespective of the actual input speed when the road load is heavy.
A shift control system for a continuously variable transmission to control a gear ratio so that an actual input speed may be equal to a target input speed, comprising:
A shift control system for a continuously variable transmission to control a gear ratio so that an actual input speed may be equal to a target input speed, comprising a controller which executes controls of:
A shift control method for a continuously variable transmission to control a gear ratio so that an actual input speed may be equal to a target input speed, comprising steps of:
