  • Automated transmission system control with zero engine flywheel torque determination
    Patent number: 6962551
    Abstract: 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.
    Type: Grant
    Filed: June 19, 1996
    Date of Patent: November 8, 2005
    Assignee: Eaton Corporation
    Inventors: Thomas A. Genise, Ronald K. Markyvech, James R. McReynolds

  • Vehicular semi-automatic shift implementation system for lever-shifted, splitter-type, compound transmission with an intent-to-shift switch operable to cause automatic control of engine fueling and initiation of a splitter shift
    Patent number: 6015366
    Abstract: 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.

  • Semi-automatic shift implementation with automatic splitter shifting
    Patent number: 5755639
    Abstract: 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.
