Abstract
Un método y un sistema para reducir la tasa de elevación de presión de frenado bajo condiciones de superficie de frenado de baja Mu, utilizando una velocidad de referencia del vehículo y una tasa de sangrado fijo para determinar si las ruedas están siendo frenadas en exceso. Cuando ocurre frenado en exceso, la tasa de elevación de presión es restringida, no permitiendo que una válvula (10) del sistema automático de frenado pase a un estado de aplicación (aproximadamente 100 psi/seg), independientemente de los niveles de aceleración de rueda. Se usa un estado de rampa en lugar del estado de aplicación y la elevación de presión es por tanto limitada a aproximadamente 30 psi/seg para mejorar el control de las ruedas. El ciclo de trabajo de rampa también es modificado para proporcionar los pasos de presión mas pequeños posibles con el equipo de válvula actual.
