  • Control system and method for maintaining a constant engine idle speed of an automatic transmission-equipped vehicle
    Patent number: 6799108
    Abstract: A control system and method maintains a constant engine idle speed during a garage shift of an automatic transmission-equipped vehicle with a torque converter. An engine control module or other processor identifies when transmission input clutch fill occurs. The engine control module increases engine output based on the transmission input clutch fill and before a decrease in engine idle speed occurs. The engine control module latches a turbine speed and a speed ratio (turbine speed/engine speed). The engine control module declares transmission input clutch fill if the latched turbine speed minus a current turbine speed is greater than the first calibration constant or if the latched speed ratio minus a current speed ratio is greater than the second calibration constant. The engine control module increases the engine output after waiting a first time delay after the transmission clutch fill.
