The sliding mode algorithm is used for air fuel ratio control, device control, and other systems because of its high responsiveness and robustness. A special feature is that the disturbance suppression characteristic can be set as needed by changing the gradient of the switching line. However, there has been no research into applying this feature. Taking note of the fact that a servo system with a high compliance can be established by lowering the disturbance suppression characteristic, this algorithm was applied to gearing control in automated manual transmissions. During gear changes, automated manual transmissions require the positioning control of a shift rod, the contact control of a sleeve and synchronizer ring, and revolution synchronizing control of the main shaft and counter-shaft by pressing in the sleeve.
