METHOD FOR CONTROLLING A DRIVETRAIN IN A MOTOR VEHICLE

摘要

A method for controlling a drivetrain ( 1 ) in a motor vehicle is disclosed, in particular in an off-road vehicle with a drive unit ( 2 ), a multi-group transmission ( 4 ) and an output. The multi-group transmission ( 4 ) comprises at least an automatic gearbox ( 8 ) and a subsequent range transfer box ( 9 ) which may be switched by means of switching elements ( 24, 25 ). On changing the ratio in the range transfer box ( 9 ), a synchronisation of the switching element ( 24 or 25 ), for switching in the range transfer box ( 9 ), is carried out by means of a controller of switching elements in the automatic gearbox ( 8 ).
