Abstract

The invention relates to a method (100) for controlling a transmission (20) in an electrified all-wheel-drive vehicle (10), comprising a first drive axle (30) which can be driven by a first motor (40) and a second drive axle (31) which can be driven by a second motor (41), wherein at least one of the two motors (40, 41) is designed as an electric motor, wherein the transmission (20) with at least two gears is assigned to the first and / or the second drive axle (30, 31), and a control unit (50), wherein the method (100) comprises the steps of: - detecting (110) a shifting requirement by the control unit (50), in particular based on a characteristic map (51) of the electric motor, - reducing (120) a drive power generated by the motor (40, 41) at the drive axle (30, 31) to a defined value and providing drive power through the non-shifting drive axle (30, 31),- Engaging (130) a starting gear (I) of the transmission (20) while the shifting drive axle (30, 31) is torque-neutral, - Shifting (140) the transmission (20) from the starting gear (I) to a target gear (II) while the shifting drive axle (30, 31) is torque-neutral, and - Increasing (150) the drive power of the motor (40, 41) at the shifting drive axle (30, 31) by the control unit (50) as soon as the target gear (II) is engaged.
