    摘要: A method of maintaining a substantially stable engine speed after a garage shift of an automatic transmission includes identifying a moment when a load from the automatic transmission is applied to an engine via a torque converter during the garage shift based on a first turbine speed change with respect to a reference engine speed change and a second turbine speed change with respect to an actual engine speed change. The method further includes generating a feed forward torque command based on a turbine speed decrement after identifying the moment when the load from the automatic transmission is applied to the engine, and controlling the engine based on the feed forward torque command to maintain a substantially stable engine speed after the garage shift.

    摘要: A vehicle includes an engine, transmission, engine control module (ECM), and transmission control module (TCM). The transmission includes an input member and an input clutch which selectively connects a crankshaft of the engine to the input member. The TCM identifies a target clutch torque of the input clutch during a creep maneuver of the vehicle, and communicates the identified target clutch torque to the ECM. The ECM maintains engine idle speed at a threshold level through the creep maneuver and a requested launch using the target clutch torque as a feed-forward term. A method includes identifying a target clutch torque of the input clutch during a creep maneuver, and communicating the identified target clutch torque to the ECM. The idle speed is maintained at a threshold level by the ECM through the creep maneuver and a detected launch using the target clutch torque as a feed-forward idle speed control term.

    摘要: A method of controlling torque output of a power-plant during launch of a vehicle having a transmission with a manually-operated clutch is disclosed. The power-plant torque is varied based on clutch pedal and throttle pedal positions using a proportional-integral-derivative (PID) control logic in an electronic fuel control system. The method includes setting power-plant idle speed, detecting clutch engagement without application of the throttle pedal, and raising power-plant torque after clutch engagement is detected. In each PID feedback loop, the method includes detecting actual power-plant speed and a rate of change in actual power-plant speed, and adjusting the raised power-plant torque in response to the determined rate of change in actual power-plant speed. The method additionally includes determining a difference between the set idle speed and the actual power-plant speed, and maintaining constant power-plant torque, if the difference between the set idle and actual power-plant speeds is within an acceptable range.
