Shift control method based on morbidity index GMDH forecast

Multi-clutch transmissions usually use a three-segment buffer characteristic curve to shift control, which has a good controlling effect when the clutch runs in a good condition. But when the clutch has problems, it may lead to a worse effect. This paper begins with the process of combination when the clutch failure happens, and proposes a GMDH forecast method on the basis of the morbidity index, which considers the predictive morbidity index as the basis of the next shifting characteristic curve, thus reducing the working strength when the clutch is in trouble, and extending the working life of the clutch.
