发明名称 METHOD FOR SHIFTING ACTUATION OF AN AUTOMATED TRANSMISSION
摘要 A method for shifting an automated transmission situated in a drive train of a motor vehicle between an engine and a drive axle and having at least one multi-speed main transmission and a two-speed range change group rear-mounted thereon. The main transmission has at least one counter-shaft with an transmission brake. A clutch engages the prime mover and the main transmission and the range change group is shifted via unsynchronized dog clutches, which are combined in pairs in a common shift set having two shift positions and one neutral position such that during a range change gearshift, both in the main transmission and in the range change group, a change between two ratio stages occurs. A range change up-shift and down-shift each include active synchronization of the dog clutch by way of the transmission brake and of the separating clutch.
