Abstract

The invention relates to a method for controlling a gearbox (4) of a vehicle powertrain (3), the gearbox (4) comprising: an input shaft (200) selectively connected to the propulsion unit (2); an output shaft (300) connected to the at least one driving wheel (8); a first gearbox unit (4A) connectable to the input shaft (200); and a second gearbox unit (4B) arranged downstream of the first gearbox unit (4A) connectable to the first gearbox unit (4A) and the output shaft (300); wherein the gearbox (4) comprises a coupling device (40) arranged downstream of the second gearbox unit (4B) for selectively disconnecting the second gearbox unit (4B) from the output shaft (300), the method comprising: controlling (s101) the coupling device (40) to disconnect the second gearbox unit (4B) from the output shaft (300) so as to achieve a freewheeling mode.
