Abstract

Un método de control de transmisión continuamente variable para controlar la entrada y la salida de aceite en una cámara de aceite de polea primaria mediante una bomba de aceite eléctrica dispuesta en una trayectoria de aceite entre la cámara de aceite de polea primaria y una cámara de aceite de polea secundaria, el método de control que incluye: comparar una temperatura de la bomba de aceite eléctrica con un primer umbral; y restringir una cantidad de cambio de una transmisión continuamente variable cuando la temperatura de la bomba de aceite eléctrica es mayor que el primer umbral.
