Shift change control method of motive for action machine equipped on vehicle automatic transmission

摘要

A method of shift control for an automated vehicle transmission which is connected to an engine by an automated clutch. The internal combustion engine includes a controllable fuel injection such that, during a gear shift from a gear under load to a target gear, before the loaded gear is disengaged, the torque of the engine is adjusted to an idling torque by modifying the fuel injection amount and, after the target gear has been engaged, to a load torque by a converse modification of the injection amount. At the beginning of the shift, at least one operating parameter, characterizing the vehicle's current operating condition, and/or a shift parameter, characterizing the desired shift operation, is detected and evaluated to adjust the shift to the operating situation. A fuel injection amount of the engine, associated with the idling torque, is variably adapted to the vehicle's operating condition and/or the shift operation depending on the evaluation.
