摘要:
A gearshift control method for a motor vehicle whose drive train comprises a turbo-charged combustion engine, a startup clutch and a shift clutch and an automatic stepped transmission, in which drive engine torque deficiencies, that occur during the build-up of load at the end of a tractive upshift, are avoided without assisting the engine with an additional device or increasing the charge pressure. The method provides that the engine accelerates at the earliest, after the disengagement of the load gear, and at the latest, at the start of the load build-up after the engagement of the target gear up to the boost threshold speed or an engine speed which is slightly above the boost threshold speed, and is loaded, during the load build-up, with a largely constant engine speed beyond the intake torque of the engine to nearly the full load torque, before slipping of the friction clutch ends.
