Abstract

A method for gearchange in a gearbox of a vehicle driving, said vehicle having a propulsion system comprising a combustion engine with an output shaft (2a), a gearbox (3) with an input shaft (3a), an electric machine (9) comprising a stator and a rotor, and a planetary gear comprising a sun gear (10), a ring gear (11) and a planet wheel carrier (12). The gearchange is carried out with the components of the planetary gear allowed to rotate with different rotational speeds and is finished by interlocking them. The combustion engine is controlled with respect to rotational speed during the gearchange towards the rotational speed required for the interlocking.
