Abstract
A vehicle is provided with a shift control device including a rolling angular velocity sensor for detecting a rolling angular velocity of a component of the vehicle, and a steering-angle angular velocity sensor for detecting a steering-angle angular velocity of a handlebar of the vehicle. The shift control device is operable to inhibit shifting of a gear ratio of a continuously variable transmission during rolling operation of the vehicle when detection signals from the rolling angular velocity sensor and the steering-angle angular velocity sensor respectively are equal to or greater than predetermined reference values.
