Gearchange control method for gearbox involves controling applied engine torque and/or torque transferred by starting coupling as well as torque transferred by change coupling

摘要

The method involves determining the output torque at the gearbox (1) output by controling the applied engine (2) torque and/or the torque transferred by the starting coupling (3) as well as by controling the torque transferred by the change coupling (12,13). The change coupling corresponding to the selected ratio remains closed until the drive torque builds up.
