A method for gear shifting in a gearbox, a gearbox and a vehicle

The invention relates to a method for gear shifting in a gearbox (6). The method comprises the following steps of: a) generate torque balance between at least two of the first planetary gear components (26, 28, 34, 36) by means of the first and second electrical machines (50, 52) and disengage at le...

Zusammenfassung:	The invention relates to a method for gear shifting in a gearbox (6). The method comprises the following steps of: a) generate torque balance between at least two of the first planetary gear components (26, 28, 34, 36) by means of the first and second electrical machines (50, 52) and disengage at least two of the first planetary gear components (26, 28, 34, 36) from each other by means of a first coupling element (38), b) generate torque balance in the range gearbox device (16) by means of the first and second electrical machines (50, 52), c) shift gear in the range gearbox device (16) to a neutral gear, so that the second planetary gear components (70, 72, 74, 78) are free to rotate in relation to each other, d) synchronize the speed between second planetary gear components (70, 72, 74, 78) in the range gearbox device (16) by means of at least one of the first and second electrical machines (50, 52), and e) engage a gear in the range gearbox device (16), by connecting at least two second planetary gear components (70, 72, 74, 78) to each other. The invention also relates to a gearbox (6), which is controlled by means of such a method and a vehicle (1), which comprises such a gearbox (6). The invention also relates to a computer program (P) and a computer program product for performing the method.
