A control system/method for an at least partially automated transmission system () includes means to determine engine fueling required to cause a gross engine output torque (T(for zero flywheel torque)) resulting in zero flywheel torque (T). The engine () 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.

Automated transmission system control with zero engine flywheel torque determination

A control system/method for an at least partially automated transmission system ( ) includes means to determine engine fueling required to cause a gross engine output torque (T (for zero flywheel torque)) resulting in zero flywheel torque (T &equals;0). The engine ( ) 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.

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.

Vehicular semi-automatic shift implementation system for lever-shifted,

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.

A check valve is positioned in the pneumatic power system of a vehicle in which air is supplied to a pneumatic compressor from an induction manifold of an engine. The compressor has an oil sump, a start and stop clutch, an air inlet, and an air outlet. A check valve is emplaced in the air inlet conduit leading from the engine manifold to the compressor to provide a one-way flow of air into the compressor when the compressor is running and to block the conduit in response to a vacuum created therein and prevent the vacuum from reaching the compressor when the compressor is not running. The valve prevents oil from the compressor sump from being drawn into the pneumatic system and fouling air actuated devices.
