Abstract | A shift control system for a continuously variable transmission (2) which has a gear ratio control means (14) for controlling gear ratio of said continuously variable transmission by determining a target gear ratio from a drive point determined on the basis of at least a throttle opening and a vehicle speed, and a vehicle distance control means (11) for maintaining a proper vehicle distance by controlling a throttle opening of an engine, comprises: a shift speed control device provided in said gear ratio control means and making a shift speed higher than a shift speed established at the time when of a vehicle distance is not controlled by said vehicle distance control means, when a vehicle distance is controlled by said vehicle distance control means. |
