    A method for gear shifting in a gearbox, a gearbox and a vehicle BACKGROUND AND PRIOR ART The present invention relates to a method for gear shifting in a gearbox accor-ding to the preamble of patent claim 1. The invention also relates to a gearboxaccording to the preamble of patent claim 15, which is controlled by means ofsuch a method. The invention also relates to a vehicle according to the pre- amble of patent claim 16, which comprises such a gearbox.
    Vehicles, and in particular heavy goods vehicles, e.g. trucks, are usuallyequipped with a gearbox connected to the combustion engine, which gearboxmay be automatic, manual or a combination thereof. ln an automated manualtransmission, a so-called Al/lT gearbox, the gearbox is controlled by an elec-tronic control device. Such a gearbox may be equipped with a main shaft anda lay shaft parallel thereto. The gearbox may also be equipped with a rangegearbox, which may constitute a separate device or be integrated in the gear-box. The main shaft is connectible to an input shaft via the lay shaft and to anoutput shaft in the gearbox via the range gearbox, if this is integrated in thegearbox. The gearbox may also be equipped with a split gear device, via whichthe lay shaft is connectible via the input shaft. ln addition to the combustion engine, also an electrical machine may be arran-ged between the combustion engine and the gearbox. The combustion enginecan together with the electrical machine deliver power to the vehicle as a hy-brid drive or as an alternative may one of the combustion engine or the electri-cal machine deliver power to the vehicle. ln a parallel hybrid powertrain a pri-mary propulsion means such as the internal combustion engine and a secon-dary propulsion means such as an electric machine may operate in parallel tosimultaneously drive the vehicle, or the propulsion means may operate to drive the vehicle one at a time.
    A brake mechanism may be arranged to retard the lay shaft in connection withchange of gears in the gearbox, in order to achieve synchronous rotationspeeds in the lay shaft and the main shaft, so that the new gear may be enga-ged without any difference in rotation speed and without any greater torqueexisting between those transmission parts in the gearbox which are brought toengage with each other at the moment the new gear is engaged. The brakemechanism is thus used to retard the lay shaft in relation to the main shaft at astage during a shifting operation when the main shaft is in the neutral position,while the lay shaft is disconnected from the main shaft. ln gearboxes of this type, the synchronization devices, comprising conicalsynchronization rings and coupling rings, are replaced by toothed operatingsleeves, which are displaced axially in order to engage with cogwheels placedon the main shaft. Each cogwheel placed on the main shaft is engaged withcorresponding cogwheel elements, which are firmly attached to the lay shaft.On shifting, the operating sleeve is displaced axially in order to engage withcoupling teeth arranged on a selectable cogwheel, in order to connect thecogwheel to, and rotation lock it, on the main shaft. The synchronization devicein the split gearbox device may also be replaced by a toothed operating slee- VG.
    A gear shifting in a known gearbox and through known methods of this typewill now be discussed for illuminating but not in any way restricting the inven-tion thereto. First the main gearbox is brought into neutral position with the ge-ars thereof disengaged from said main shaft. Thereafter a gear shifting actioninvolving a shifting of gear in the split gearbox is performed. The engine is thencontrolled to obtain a rotational speed of the output shaft of the engine corres-ponding to a rotational speed of the input shaft of said gearbox being synchro-nous with respect to the rotational speed of the output shaft of the transmissiondetermined by the present rotational speed of the driven axel of the vehicle forthe gear to be selected by said shifting action. The synchronization means ofthe main gearbox is then controlled to act upon the main shaft until the rotatio- nal speed of the main shaft is synchronous with respect to the rotational speedof the input shaft and the output shaft of the transmission, so that the gear shif-ting may be completed in the main gearbox without any substantial speed dif-ference existing between the engaging parts in the moment of engagement.However, the period of time needed for said synchronization means of themain gearbox to act for obtaining synchronous rotational speed thereof may becomparatively long. Also, the gear shifting in sequence of the main and sp|itgearboxes within the known gearboxes needs an essentially long period of time to perform.
    The document WO2013020761 relates to a method for shift control of an au-tomated gearbox in order to achieve short range shift times.
    The document US20130008271 relates to a transmission device and a methodfor operating such a transmission device in which an auxiliary group shiftingunit and a central synchronizing unit are actuated in parallel in a shifting opera- tion.
    SUMMARY OF THE INVENTION Despite prior art, there is a need to develop a method, which makes it possibleto shorten the period of time needed for completing the gear shifting operationand which increases comfort when completing the gear shifting operation.
    The object of the present invention is thus to provide a method for gear shiftingin a gearbox of the type defined in the introduction, which makes it possible toshorten the period of time needed for completing the gear shifting operation.Another objective of the present invention is to provide a method, which in-creases comfort when completing the gear shifting operation. These objectivesare achieved with a method, which is characterised by the features specified inpatent claim 1.
    These objectives are also achieved with a gearbox, which is characterised by the features specified in patent claim 15.
    These objectives are also achieved with a vehicle, which is characterised bythe features specified in patent claim 16.
    According to the invention, an advantageously short delay time can beachieved for completing the gear shifting operation in the gearbox when thegear in the main gearbox device is shifted, a synchronous rotational speed be-tween the second split cogwheel and the input shaft by means of the electricmachine is generated, and the gear in the split gearbox device is shifted. Pref-erably, is the main gearbox device shifted substantially simultaneously as asynchronous rotational speed between the second split cogwheel and the inputshaft by means of the electric machine is generated, and the gear in the splitgearbox device is shifted. As a result, a short delay time can be achieved forcompleting the gear shifting operation and the comfort for the driver and pas-sengers in the vehicle increases when completing the gear shifting operation.According to an embodiment of the invention the torque balance between thefirst main cogwheel on the main shaft and the cogwheel element on the layshaft is generated by means of the electrical machine. Preferably, when gen-erating the torque balance in such a way the first and second main cogwheelmay be engaged and disengaged on the main shaft by means of an axialmovable main gear sleeve. Thus, a conventional synchronization means com-prising conical sleeves and synchronization rings can be replaced by the axialmovable main gear sleeve. This means that the time needed for completingthe gear shifting action may be considerably shortened.
    According to a further embodiment of the invention the first and second splitcogwheels may be engaged and disengaged on the input shaft by means of anaxial movable split gear sleeve. Thus, a conventional synchronization ar- rangement comprising conical sleeves and synchronization rings can be re- placed by the axial movable main gear sleeve, which means that the time needed for completing the gear shifting action may be considerably shortened.
    When shifting gear in the main and split gearboxes in the gearbox the gearboxis synchronized from two directions, which means that the output shaft of thegearbox having a rotationa| speed determined by the rotationa| speed of thedriven axle of the vehicle, and the input shaft of the gearbox having a rotationa|speed controlled by the electrical machine and depending on the gear to beselected by the gear shifting. This that the synchronous rotationa| speedneeded for completing the gear shifting operation may be reached earlier thanif shifting in sequence were used.
    The invention also relates to a computer program and a computer program product for performing the method according to the present invention.

The engine 4, which may be an internal combustion engine, is connectedto the gearbox 6 by means of a controllable clutch 3. The gearbox 6 is furtherconnected to driving wheels 8 of the vehicle 1 via a propeller shaft 10. An elec-trical machine 5 is arranged between the clutch 3 and the gearbox 6.
    Fig. 2 shows a sectional view of a gearbox which is controlled by the methodaccording to the present invention. The gearbox 6 is provided with a main shaft12 and a lay shaft 14 parallel thereto. The gearbox 6 is also provided with arange gearbox 16, which is integrated in the gearbox 6. The main shaft 12 isconnectible to an input shaft 18 in the gearbox 6 via the lay shaft 14, and to anoutput shaft 20 in the gearbox 6 via the range gearbox 16. One part of the con-trollable clutch 3 is arranged on the input shaft 18. The gearbox 6 is equippedwith a split gearbox device 22, via which the lay shaft 14 is connectible via theinput shaft 18. A brake mechanism 2 is connected with the lay shaft 14 and isarranged to retard the lay shaft 14 in connection with change of gears in thegearbox 6. The gearbox 6 is also equipped with a main gearbox device 7, viawhich the lay shaft 14 is connectible via the main shaft 12. The electrical ma-chine 5 is arranged on the input shaft 18 and may generate driving torque orbrake torque on the input shaft. The electrical machine 5 is connected to anelectrical accumulator which delivers electrical power to the electrical machine5 or receives electrical power from the electrical machine 5 when the electrical machine 5 generates brake torque on the input shaft.
    The main gearbox device 7 comprises operating main gear sleeves 24a- 24c,which are equipped internally with toothing 26. Each main gear sleeve 24a-24c is displaced axially through an operating fork 28 to be brought into enga-gement with main cogwheels 30a-30d placed on the main shaft 12. The maincogwheels 30a-30d are free to rotate in relation to the main shaft 12 by meansof the bearings 27. The operating forks 28 are activated through the operatingelement 29, which may consist of pneumatic or hydraulic cylinders. Only oneoperating fork 28 and one operating element 29 are shown schematically in Fig. 2. Each main cogwheel 30a- 30d, placed on the main shaft 12, is engagedwith corresponding cogwheel elements 32a-32d, which are anti-rotationallyconnected with the |ay shaft 14. On shifting, the operating sleeve 24a- 24c isdisplaced axially from a disengaged position to an engaged position in order toengage with coupling teeth 34 arranged on a selectable main cogwheel 30a-30d in order to connect the cogwheel 30a-30d to, and rotation lock it, on themain shaft 12. Alternatively, the axially displaceable main gear sleeves 24a-24c may also be brought into engagement with the main cogwheels 30a-30d by means of synchronization means 21.
    The split gear box device 22 comprises an operating split gear sleeve 25,which is equipped internally with toothing 23. The split gear sleeve 25 is disp-laced axially through an operating fork 31 to be brought into engagement withsplit cogwheels 30e-30f placed on the input shaft 18. The split cogwheels 30e,30f are free to rotate in relation to the input shaft 18 by means of the bearings36. The split cogwheel 30e may be arranged by means of bearings on themain shaft 12. The operating fork 31 is activated through an operating element33, which may consist of pneumatic or hydraulic cylinders. Each split cogwheel30e- 30f, placed on the input shaft 18, is engaged with corresponding cogwhe-el elements 32e-32f, which are anti-rotationally connected with the |ay shaft14. On shifting, the split gear sleeve 25 is displaced axially from a disengagedposition to an engaged position in order to engage with coupling teeth 35 ar-ranged on a selectable split cogwheel 30e-30f in order to connect the splitcogwheel 30e-30f to, and rotation lock it on, the input shaft 18, even if one ofthe split cogwheels 30e-30f are arranged rotatably on the main shaft 12 bymeans of bearings. Alternatively, the axially displaceable split gear sleeve 25may also be brought into engagement with the split cogwheels 30e-30f by me-ans of a synchronization arrangement 37. However, it is possible to let theelectrical machine 5 to take over the synchronization between the input shaftand the |ay shaft when shifting gears in the split gearbox.
    The shifting of gears and thus the main gear sleeves 24a- 24c and the splitmain sleeve 25 are controlled by a control unit 44, which is connected to theoperating elements 29, 33. The control unit 44 receives information from amemory 46 about shifting properties, whereby the control unit 44 uses the in-formation for the shifting operation. The control unit 44 is preferably run by acomputer 48 including a computer program P for carrying out the method ac-cording to the invention, in which a software algorithm provides calculationsabout the shifting of gears. Also, position detectors 50 arranged at the opera-ting forks 28, 31 are connected to the control unit 44. The position detectors 50provide the control unit 44 with information about the axial position of respec-tive main gear sleeves 24a- 24c and the split main sleeve 25.
