摘要

A method is provided to control a hybrid powertrain, comprising: a) engaging a gear corresponding to either a gear pair connected with a first planetary gear in the gearbox or corresponding to a gear pair connected with a second planetary gear and an output shaft; b) selecting a gear by connecting two rotatable components in the first planetary gear with each other, via a first coupling device and/or connecting two rotatable components in the second planetary gear with each other, via a second coupling device; and c) controlling a switch such that a first electrical machine is set into a waiting state, if the second coupling device connects the two rotatable components of the second planetary gear with each other, and such that a second electrical machine is set into a waiting state, if the first coupling device connects the two rotatable components of the first planetary gear with each other.
