Method for shift control of automatic transmission in powertrain of commercial vehicle, involves increasing switching dynamic with increasing nominal driving resistance, which is corrected depending on operational parameters

摘要

The method involves controlling a clutch actuator for disengagement and engagement of a friction clutch and gear plates for removing and inserting gears in a transmission by switching dynamic (SD) during shift operation of a drive motor. The switching dynamic of the shift operation is determined depending on corrected driving resistance (FFW-kor). The switching dynamic is increased with increasing nominal driving resistance (FFW-nom). The nominal driving resistance is corrected depending on operational parameters e.g. vehicle mass.
