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 para controlar la transmisión continuamente variable incluye: una etapa de cálculo del valor de comando de corriente de calcular un valor de comando de corriente para la bomba de aceite de conformidad con un estado de operación; una etapa de limitación de corriente de limitar el valor de comando de corriente a una corriente de límite inferior en que el deslizamiento de correa no ocurre cuando una presión de aceite en la cámara de aceite primaria cae por debajo de una presión de aceite de límite inferior en la cámara de aceite primaria en que no ocurre el deslizamiento de correa; y una etapa de control de bomba de accionar la bomba de aceite utilizando el valor de comando de corriente para controlar una posición de pistón de la cámara de aceite primaria.
