Abstract
After the throttle opening degree has exceeded a predetermined value, a target value in engine speed that varies in correspondance with the throttle opening degree is modified to vary in a second pattern whereby the continuously variable transmission is shifted to a predetermined reduction ratio and then kept operating at the predetermined reduction ratio so as to allow the engine speed to increase with the variation in vehicle speed, thus providing an increased acceleration feel.
