Abstract
A method for controlling an internal combustion engine of a vehicle having a continuously variable transmission is disclosed. When a driven pulley speed is less than a predetermined driven pulley speed and an actual engine speed is less than an engine speed causing a driving pulley speed to be a driving pulley engagement speed: controlling the engine to increase the actual engine speed to increase the driving pulley speed to be at least the driving pulley engagement speed. When the driven pulley speed is above the predetermined driven pulley speed, the actual engine speed is greater than the engine speed causing the driving pulley speed to be the driving pulley engagement speed, and the desired engine speed is less than the engine speed causing the driving pulley speed to be the driving pulley engagement speed: controlling the engine to operate under conditions corresponding to an engine braking speed.
