摘要:
A control system/method for an at least partially automated transmission system (100) includes means to determine engine fueling required to cause a gross engine output torque (TEG (for zero flywheel torque)) resulting in zero flywheel torque (TFW=0). The engine (102) is caused to be fueled to the level required to cause zero flywheel torque at certain predetermined conditions, such as, for example, when disengaging a currently engaged ratio or during throttle recovery.

摘要:
A semi-automatic shift implementation system (100) for a manually lever (57) shifted, splitter-type transmission (10). Lever shifts are semi-automatically implemented by automatic splitter shifting and, upon sensing transmission neutral, automatic control of engine fueling to cause substantially synchronous conditions for engagement of a target ratio.

摘要:
A semi-automatic shift implementation system (100) for a lever-shifted mechanical transmission (10) includes an intent-to-shift sensor (122), such as an intent-to-shift button (120). Upon sensing an intent to shift, a controller (146) will cause the engine to be fueled to minimize torque-lock conditions at jaw clutches to be disengaged.
