Shift control system for continuously variable transmission
First Claim
1. A shift control system for a continuously variable transmission which has a gear ratio control means for controlling a 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 for maintaining a proper vehicle distance by controlling a throttle opening of an engine,wherein said gear ratio control means includes a shift speed control device for making a shift speed higher than a shift speed established when a vehicle distance is not controlled, when a vehicle distance is controlled by said vehicle distance control means.

Abstract
A shift control system for a continuously variable transmission CVT) has a gear ratio controller for controlling the gear ratio of CVT by determining a target gear ratio from a drive point determined on the basis of at least a throttle opening and a vehicle speed. The shift control system also has a vehicle distance controller for maintaining a proper vehicle distance by controlling the throttle opening of an engine. A shift speed control device provided in the gear ratio controller increases the shift speed from the shift speed established at the time the vehicle distance is not controlled by the vehicle distance controller, when the vehicle distance is controlled by the vehicle distance controller.
