Abstract
Una función hidráulica puede extenderse y retraerse bajo el control de una unidad de válvula electro- hidráulica. Una palanca de comando que puede ser movida por el conductor en la región de extensión, centra y de retracción. Un sensor genera una senal de posición de palanca. Una unidad de comando de palanca electrónica recibe la senal de posición de palanca y genera una sela de comando de válvula. Una unidad de control de válvula electrónica está alejada de la unidad de comando de palanca y comunicada con la misma. La unidad de control de válvula electrónica controla la comunicación de fluido hidráulico con la función hidráulica en respuesta a la senal de comando de válvula. Un método para generar la senal de comando de válvula incluye generar una senal de comando que es proporcional a la senal de posición de palanca cuando la palanca se mueve de manera relativamente lenta, y generar una sela de comando que está basada en una excursión máxima de la palanca en las regiones de extensión y retracción cuando la palanca se mueve en forma relativamente rápida. Las senales de comando son transmitidas a la unidad de control de válvula después de un período de tiempo de retardo que es una fracción de un período de la oscilación de movimiento de la palanca.
