Abstract
Una transmisión incluye una válvula de enganche con estados trabado y destrabado. En el estado destrabado, la válvula de enganche dirige una presión de control a un circuito de aplicación del embrague. En el estado trabado, al que se entra en respuesta a una presión de control superior a una presión de enganche, la válvula de enganche dirige una presión de línea al circuito de aplicación del embrague. Un regulador maneja la transición de trabado a destrabado de manera diferente, según el par de entrada de la transmisión y el estado de cambio. En un par de entrada de la transmisión alto, el regulador primero reduce la presión de control para acelerar rápidamente una bobina en la válvula de enganche y luego aumenta la presión de control para impedir el deslizamiento del embrague. En un par bajo, el regulador reduce la presión a un valor intermedio durante la transición y luego la vuelve a reducir. Con pares moderados, el regulador reduce la presión directamente a una presión objetivo en una sola etapa.
