发明名称 METHOD FOR OPERATING A DRIVETRAIN
摘要 A method for operating a drivetrain comprising an automatic transmission (2) and a power engine (1) such that, in order to carry out a shift operation, in particular an upshift, a clutch (4) connected between the automatic transmission (2) and the power engine is first disengaged and, after carrying out the shift operation, engaged again. A vehicle speed gradient, a transmission input rotational speed gradient, a transmission output rotational speed gradient or a wheel rotational speed gradient is monitored, and after the shift operation has been carried out, the clutch (4) is engaged in such a manner that the gradient being monitored lies within a defined range of values or assumes a defined value.
