Abstract
Un método y aparato para detectar un filtro de aceite de transmision restringido o derivado proveyendo transductores de presion a ambos lados del filtro de aceite con lo cual el diferencial de presion indicará la extension de restriccion del filtro de aceite. Una primera alarma es activada en un primer diferencial de presion para indicar un filtro restringido y la necesidad de recambio del filtro. Una segunda alarma, de nivel más alto, es activada para indicar que el filtro ha sido derivado y se reduce la velocidad del motor para permitir que la presion y el diferencial de presion caigan hasta el punto en que el filtro ya no es derivado. Esto permite que el vehículo sea operado con capacidades limitadas para permitir que sea llevado al taller para cambiar el filtro. Si la velocidad disminuida del motor es insuficiente para reducir la diferencial de presion para detener la derivacion, entonces la velocidad del motor se reduce adicionalmente a una regulacion baja y la transmision es pasada a punto neutral. El filtro debe ser reemplazado antes que el vehículo pueda ser operado nuevamente para impedir averías en la unidad hidrostática de la transmision.
