ELECTRONIC CONTROLLER FOR A CVT RATIO. |
摘要 |
A continuously variable transmission (CVT) is provided for use on a recreational or utility vehicle. The CVT is electronically controlled by at least one control unit of the vehicle. The CVT includes a primary pulley (50) having a first sheave (100) and a second sheave (102)moveable relative to the first sheave. An actuator controls movement of the second sheave. The method includes: determining a speed of the engine (452); detecting a throttle demand (458); determining a pulley control variable (K-Factor) based on an operator input device (111), the CVT including a first and a second pulley, the first pulley (50) being moveable by an actuator (76) to modulate a gear ratio of the CVT; calculating a target engine speed (460) based on the throttle demand and the pulley control variable; and calculating a target position (470) of the first pulley of the CVT based on the calculated target engine speed and the determined speed of the engine. |
