    摘要: A partially automated mechanical transmission system (92) includes a splitter-type compound transmission (10) and controls for automating splitter shifting upon manual selection of the highest main section ratio position (ninth/tenth). Logic is provided to provide an optimized response to manual shifting into main section neutral from the highest main section ratio position.

    摘要: A shift control system is provided that is suitable for semi-automatic transmissions in heavy duty vehicles. The torque modulation system includes logic circuitry that employs a ramping torque function or algorithm to control the acceleration of torque, both positive and negative, and/or provides a longer dwell time in the torque clutch disengagement range. Moreover, dwell time at peak is not required. A method for improving gear disengagement and shift control in accordance with the principles of the invention is also disclosed.
