Abstract

A method for shifting gear in a gear-by-wire system in a vehicle (1), comprising the steps of: determining if a reliable gear signal is obtainable from a gear shifting means (7), changing from a first mode for gear shifting in which a gear shift is initiated by manually actuating a clutch controlling means (21) and indicating a desired gear through the gear shifting means to a second mode for gear shifting if a reliable gear signal cannot be obtained, obtaining an appropriate gear in the second mode, and shifting to the appropriate gear if the clutch controlling means in the second mode is manually influenced and the appropriate gear is different from a currently engaged gear. A computer program (20), a computer program product (19), a vehicle and an electronic control unit for performing the method are also disclosed.
