A method of operating an automatic start/stop system in a vehicle using a torque converter is disclosed. A method and system for operating an automatic start/stop system in a motor vehicle is disclosed, wherein the motor vehicle has an internal combustion engine, an automatic transmission, and a torque converter with an impeller disconnect clutch. The controller may implement an engine start/stop system by interrupting fuel at the appropriate time to stop the engine and restarting the engine when propulsion is required. During an engine start/stop event, the engine is automatically shut down and the impeller clutch of the torque converter can be disengaged to disengage the impeller from the engine, thereby providing fuel savings and emission reductions. |
