Abstract

Un método para controlar una transmisión continuamente variable es un método de control para controlar la entrada/salida de aceite hacia/desde una cámara de aceite primaria utilizando una bomba de aceite provista en un pasaje de aceite entre la cámara de aceite primaria y una cámara de aceite secundaria. El método incluye: una etapa de determinación de determinar si una velocidad de cambio descendente requerida es mayor que un valor permisible; una etapa de control de posición de establecer una posición de pistón objetivo de la cámara de aceite primaria de conformidad con un estado de operación de un vehículo y realizar un control de posición de un pistón de la cámara de aceite primaria con base en la posición de pistón objetivo; una etapa de control hidráulico de establecer una presión de aceite objetivo de la cámara de aceite primaria de conformidad con el estado de operación y realizar un control hidráulico de la cámara de aceite primaria con base en la presión de aceite objetivo; y una etapa de control de establecimiento de retroalimentación de aumentar la ponderación de acuerdo con un control de retroalimentación de posición con base en la posición de pistón objetivo en la etapa de control de posición cuando se determina que la velocidad de cambio descendente es menor que el valor permisible en la etapa de determinación y de aumentar la ponderación de acuerdo con un control de retroalimentación hidráulico con base en la presión de aceite objetivo en la etapa de control hidráulico cuando se determina que la velocidad de cambio descendente es mayor que el valor permisible.
