DETALJERAD BESKRIVNING AV EN UTFORINGSSFORM AV UPPFINNINGEN
Fig 1 visar en drivlina far ett tungt fordon 1. Drivlinan innefattar en forbranningsmotor 2, en krafttransmission 3 i form av exempelvis
en stegad vaxellada, en kontinuerligt variabel transmission (CVT)
eller en direkt transmission, ett antal drivaxlar 4 och drivhjul 5. MeIlan forbranningsmotorn 2 och vaxelladan 3 innefattar drivlinan ett mellanliggande parti 6. Fig 2 visar en del av konnponenterna i det mellanliggande partiet 6 mer i detalj, narmare bestamt de som
aven finns att finna i tidigare kanda drivsystem, sasom det enligt
SE 536 329. Forbranningsmotorn 2 är forsedd med en utgaende axel 2a och vaxelladan 3 med en ingaende axel 3a i det mellanliggande partiet 6. Forbranningsmotorns utgaende axel 2a är koaxiellt anordnad i forhallande till vaxelladans ingaende axel 3a. For-
branningsmotorns utgaende axel 2a och vaxelladans ingaende axel 3a är roterbart anordnade runt en gemensam rotationsaxel 7. Det mellanliggande partiet 6 innefattar ett hus 8 som innesluter en forsta elektrisk maskin 9 och en planetvaxel. Den elektriska maskinen 9 innefattar pa sedvanligt satt en stator 9a och en rotor 9b.
Statorn 9a innefattar en statorkarna som är fast pa lampligt satt
pa husets 8 insida. Statorkarnan innefattar statorns lindningar. Den forsta elektriska maskinen 9 är anpassad att under vissa driftstillfallen utnyttja lagrad elektrisk energi for att tillfora drivkraft till vaxelladans ingaende axel 3a och under andra driftstillfallen
utnyttja rorelseenergin hos vaxelladans ingbende axel 3 for att utvinna och lagra elektrisk energi.
Planetvaxeln är anordnad vasentligen radiellt invandigt om den
elektriska maskinens stator 9a och rotor 9b. Planetvaxeln innefat-
tar pa sedvanligt satt ett solhjul 10, ett ringhjul 11 och en planethjulhallare 12. Planethjulhallaren 12 bar upp ett antal kugghjul 13 som är roterbart anordnade i ett radiellt utrymme mellan solhjulets 10 och ringhjulets 11 kuggar. Solhjulet 10 är fast pa en perifer yta
hos forbranningsmotorns utgaende axel 2a. Solhjulet 10 och for-
branningsmotorns utgaende axel 2a roterar som en enhet med ett forsta varvtal ni. Planethjulhallaren 12 innefattar ett fastparti 12a som är fast pa en perifer yta hos vaxelladans ingaende axel 3a med hjalp av ett splines-forband 14. Med hjalp av detta forband
kan planethjulhallaren 12 och vaxelladans ingaende axel 3a rotera
som en enhet med ett andra varvtal n2. Ringhjulet 11 innefattar en utvandig perifer yta pa vilken rotorn 9b är fast monterad. Rotorn 9b och ringhjulet 11 utgor en roterbar enhet som roterar med ett tredje varvtal n3.
Drivsystemet innefattar ett forsta lasmedel genom att forbranningsmotorns utgaende axel 2a är forsedd med ett forskjutbart kopplingsorgan 15. Kopplingsorganet 15 är fast pa forbranningsmotorns utgaende axel 2a med hjalp av ett splines-forband 16.
Kopplingsorganet 15 ar i detta fall vridfast anordnat pa forbran-
ningsmotorns utgaende axel 2a och forskjutbart anordnat i en axiali riktning pa forbranningsmotorns utgaende axel 2a. Kopplingsorganet 15 innefattar ett kopplingsparti 15a som är forbindbart med ett kopplingsparti 12b hos planethjulhallaren 12. Ett schema-
11
tiskt visat forskjutningsorgan 17 är anpassat att forskjuta kopplingsorganet 15 mellan ett forsta !age da kopplingspartierna 15a, 12b inte är i ingrepp med varandra motsvarande ett frigoringslage hos det forsta lasmedlet och ett andra !age da kopplingspartierna
15a, 12b är i ingrepp med varandra motsvarande ett laslage hos
det forsta lasmedlet. I detta laslage kommer forbranningsmotorns utgaende axel 2a och vaxelladans ingaende axel 3a att vara hoplasta och darmed dessa samt den elektriska maskinens rotor att rotera med samma varvtal. Detta tillstand kan benamnas last pla-
net. Lasmekanismen kan aven med fordel ha den utformning som finns beskriven i det svenska patentet SE 536 559 och innefatta en med forsta splines forsedd hylsa som i frigoringslaget griper in med andra splines pa en forsta komponent hos planetvaxeln och i laslaget griper in med tredje splines pa en andra komponent hos
planetvaxeln. Den forsta komponenten är i detta fall foretradesvis
planethjulshallaren och den andra komponenten solhjulet. Lasmekanismen kan da vara utformad som en ringformad hylsa som vasentligen koncentriskt omsluter planethjulshallaren. Lasmedlet kan aven vara bildat av en lamplig typ av friktionskoppling.
En elektrisk styrenhet 18 är utformad att styra forskjutningsorganet 17. Styrenheten 18 är aven utformad att avgara vid vilka till-fallen som den elektriska maskinen ska arbeta som motor och vid vilka tillfallen som den ska arbeta som generator. For att avgora
detta kan styrenheten 18 mottaga aktuell information om lampliga
driftsparametrar. Styrenheten 18 kan vara en dator med programvara for detta andamal. Styrenheten 18 styr en schematiskt visad regleringsutrustning 19 som reglerar flodet av elektrisk energi mellan ett hybridbatteri 20 och den elektriska maskinens stator-
lindningar 9a. Vid tillfallen som den elektriska maskinen 9 arbetar
12
som motor tillfors lagrad elektrisk energi fran hybridbatteriet 20 till statorn 9a. Vid tillfallen som den elektriska maskinen arbetar som generator tillfors elektrisk energi fran statorn 9a till hybrid batteriet 20. Hybridbatteriet 20 levererar och lagrar elektrisk energi med en
spanning som är av storleksordningen 300-900 Volt. Da det mellanliggande partiet 6 mellan forbranningsmotorn 2 och vaxelladan 3 i ett fordon är begransat erfordras att den elektriska maskinen 9 och planetvaxeln utgor en kompakt enhet. Planetvaxelns komponenter 10, 11, 12 anordnas har vasentligen radiellt invandigt om
den elektriska maskinens stator 9a. Rotorn 9b hos den elektriska
maskinen, ringhjulet 11 hos planetvaxeln, forbranningsmotorns utgaende axel 2a och vaxelladans ingaende axel 3a är har roterbart anordnade runt en gemensam rotationsaxel 5. Med ett sadant utforande upptar den elektriska maskinen 9 och planetvaxeln ett re-
lativt litet utrymme. Fordonet 1 är utrustat med en motorstyrnings-
funktion 21 med vilken forbranningsmotorns 2 varvtal ni och/eller moment kan regleras. Styrenheten 18 har darmed mojlighet att aktivera motorstyrningsfunktionen 21 och skapa ett momentlost till-stand i vaxelladan 3 vid i- och urlaggning av vaxlar i vaxelladan 3.
Naturligtvis kan drivsystemet istallet for att styras av en enda sty-
renhet 18 styras av flera olika styrenheter.
Den sa langt beskrivna och i Fig 2 visade delen av ett drivsystem som ett fordon pa vilket ett forfarande enligt uppfinningen kan ut-
-lams forekommer i drivsystemet enligt SE 536 329. Nu kommer en del av det drivsystemet som kan laggas till till denna del for utforande av uppfinningen att beskrivas under hanvisning till Fig 3.
Drivsystemet, narmare bestamt det mellanliggande partiet 6, upp30 visar aven en andra elektrisk maskin 30 med en stator 31 med
13
statorlindningar och en rotor 32 som är forbunden med forbranningsmotorns utgaende axel 2a. Ett andra lasmedel 33, vilket kan ha liknande utformning som det forsta lasmedlet 34, vilket är narmare framstallt i Fig 2, är utformat att i ett frigoringslage skilja en
forsta, narmast forbranningsmotorn anordnad part 35 av forbranningsmotorns utgaende axel fran en andra part 36 darav forbunden med planetvaxelns solhjul 10, sa att den andra elektriska maskinens rotor 32 och solhjulet 10 tillats rotera oberoende av den forsta parten 35 hos forbranningsmotorns utgaende axel. Det
andra lasmedlet är overforbart till ett laslage i vilket de bada par-
terna 35, 36 hos forbranningsmotorns utgaende axel är hoplasta och darmed den forsta parten 35 är ihoplast med den andra elektriska maskinens rotor. Styrenheten 18 är utformad att styra bransletillforsel till forbranningsmotorn 2 och utbyte av elektrisk energi
mellan a ena sidan den forsta elektriska maskinen 9 och den andra
elektriska maskinen 30 och a andra sidan i forekommande fall lager av elektrisk energi, sasom batterier, och elektriska hjalpaggregat och !aster hos fordonet, sasom servostyrenhet, pumpar, kylaggregat och dylikt.
Genom det tillkommande anordnandet av den elektriska maskinen 30 samt det andra lasmedlet 33 uppnas en rad positiva egenskaper hos drivsystemet, men det papekas an en gang att forekomsten av det andra lasmedlet och forbranningsmotorn hos kraftaggre-
gatskonfigurationen inte är nadvandig far att realisera forfarandet
enligt uppfinningen. Kars fordonet med det forsta lasmedlet 34 i laslage och exempelvis det andra lasmedlet 33 i laslage, och det uppstar onskemal om att overfora det forsta lasmedlet 34 i frigoringslage, da styrs kraftaggregatskonfigurationen mot momentba-
14
lans mellan de komponenter som är ihoplasta, dvs planethjulhallaren 12 och solhjulet 10, via det forsta lasmedlet 34 mot momentbalans. Detta kan da goras genom att styra den forsta elektriska maskinen 9 och atminstone en av den andra elektriska maskinen
och forbranningsmotorn 2, eftersom det andra lasmedlet 33 är i laslage, mot namnda momentbalans, varvid da aven mojlighet finns till energilagring i hybridbatteriet 30 om detta onskas. Darvid galler att momentbalans är uppnadd nar foljande relation mellan de paforda momenten är uppfyllda for den i Fig 3 visade exempel-
konfigurationen:

Zs är antal tander hos solhjulet,
Zr är antal tander hos ringhjulet.
Foljaktligen avses med momentbalans det tillstand da ett vridmo-
ment verkar pa ett hos planetvaxeln anordnat ringhjul, motsvarande produkten av momentet som verkar pa planetvaxelns planethjulshallare och planetvaxelns utvaxlingsforhallande samtidigt som ett vridmoment verkar pa planetvaxelns solhjul, motsvarande
produkten av momentet som verkar pa planethjulshallaren och (1 minus planetvaxelns utvaxlingsforhallande). Vid sadan momentbalans overfor namnda forsta lasmedel 34 inget moment mellan planetvaxelns komponenter. Nar sa momentbalans har uppnatts kan
det fOrsta lasmedlet 34 pa enkelt satt overforas till frigoringslaget,
sa att planetvaxelns komponenter inte langre är ihoplasta.
Hos det uppfinningsenliga forfarandet styrs den forsta elektriska maskinen 9 att uppna efterfragat moment att overfora pa planet-
vaxelns utgaende axel, dvs vaxelladans ingaende axel 3a, samti-
digt som varvtalsstyrning utfors av antingen forbranningsmotorn 2 eller den andra elektriska maskinen 30 for bringande av varvtalet hos planetvaxelns ingaende axel 2a mot varvtalet hos dess utgaende axel 3a, sa att sedan overforing av det forsta lasmedlet 34
till laslaget kan ske nar vasentligen samma eller samma varvtal
uppnatts has den ingaende 2a och utgaende 3a axeln hos planetvaxeln. Det uppfinningsenliga forfarandet mojliggor aven overforing av det forsta lasmedlet fran frigoringslaget till laslaget utan nagot momentavbrott i fordonets drivlina och med frihet for fordo-
nets forare, farthallare eller annan momentreglerande funktion hos
fordonet att bestamma och andra drivlinemomentet under forfarandet.
En stor fordel med ett drivsystem enligt Fig 3 med eller utan det
andra lasmedlet är mojligheten till kontinuerlig elkraftsforsorjning
av elektriska aggregat i samtliga driftsfall med inkopplad forbranningsmotor i fortvarighet. Detta klaras normalt inte av med hybridlosningar med bara en elektrisk maskin. Nar det forsta lasmedlet är i laslaget forsorjs namnda elektriska aggregat genom att den
efterfragade elektriska effekten till de elektriska hjalpaggregaten
16
och elektriska lasterna hos fordonet fordelas vasentligen lika mellan de elektriska maskinerna. Pa sa satt minimeras forlusterna i de elektriska maskinerna genom att momentet per elektrisk maskin halveras jamfOrt med att en elektrisk maskin hade statt for hela
den elektriska effekten. Eftersom de elektriska maskinernas for-
lusteffekter skalar vasentligen mot det palagda momentet i kvadrat sa innebar detta vasentligen en halvering av de elektriska maskinernas forluster. Dock är en sadan fordelning (50/50) eventuellt inte optimal i det fall de bada elektriska maskinerna har dimens-
ioner som skiljer sig avsevart fran varandra, men da stravas an-
dock efter att valja namnda proportioner under att ha denna optimala fordelning i atanke.
Nar det forsta lasmedlet är tippet kommer den forsta elektriska
maskinen att bestamma momentet i drivlinan. Forbranningsmotorn
varvtalsstyrs till en driftspunkt som valjs genom att forlustminimera forbranningsmotorforluster ihop med elektriska maskins- och inverter-forluster. Den andra elektriska maskinen anvands da till att balansera effekten till eventuellt forekommande energilager, elekt-
riska aggregat och den forsta elektriska maskinen. En stor styrka
är att kraftforsorjningen av de elektriska aggregaten kan ske aven om fordonet inte utrustats med elektriskt energilager. Forsorjningen kan aven ske kontinuerligt under alla typer av upp- och nervaxlingar, under krypkOrning, under ivagkorning och inbroms-
ning. Alla korfall utom elektrisk korning och bromsregenerering gar
att utfora utan elektriskt energilager eller med ett defekt energilager. Vid driftsfall utan eller med defekt elektriskt energilager sa kommer normalt den andra elektriska maskinen spanningsstyras for att uppratthalla ratt spanningsniva pa DC-Ianken (matnings-
spanningen till de tva invertrarna som är anslutna till statorerna
17
hos de elektriska maskinerna). Man kan aven tanka sig att istallet den forsta elektriska maskinen spanningsstyrs i vissa fall. Spanningsstyrning är en "mod" i invertern dar en spanning begars fran invertern. Invertern styr dä den elektriska maskinens vridmoment
sa att den begarda spanningen uppratthalls pa inverterns mat-
ningssida.
Fig 4 visar forenklat ett drivsystem som skiljer sig fra n det enligt Fig 3 genom att forbranningsmotorn 2 är permanent forbunden
med den andra elektriska maskinens rotor 32, medan Fig 5 forenklat visar ett drivsystem som helt saknar forbranningsmotor. Utforingsformer av det uppfinningsenliga forfarandet är genomforbara hos fordon med dessa alternativa drivsystem.
Fig 6 illustrerar ett flodesschema av ett forfarande enligt en utfo-
ringsform av foreliggande uppfinning utfort pa ett fordon med ett drivsystem av den typ som visas i Fig 3-5. Det antages att fordonet [(ors med det forsta lasmedlet i frigoringslage. Forfarandet startas da genom att i ett forsta steg Si den forsta elektriska maskinen
styrs att uppna efterfragat drivlinemoment, och detta steg Si utfors
under hela forfarandet. I ett andra steg S2 varvtalsstyrs en part hos kraftaggregatskonfigurationen vilken verkar pa planetvaxelns ingaende axel mot och till varvtalet hos planetvaxelns utgaende axel. Sedan stalls i ett tredje steg S3 fragan om varvtalet hos pla-
netvaxelns ingaende och utgaende axel är samma eller vasentli-
gen samma, och om svaret pa denna fraga ar la" overfors det forsta lasmedlet till laslage i steg S4 via styrning av forskjutningsorganet 17 hos utforingsformen enligt Fig 2.

Datorprogramkod for implementering av ett forfarande enligt uppfinningen är lampligen inkluderad i ett datorprogram som är inlasningsbart till internminnet hos en dator, sasom internminnet hos en elektronisk styrenhet hos ett fordon. Ett sadant datorprogram
är lampligen tillhandahallet via en datorprogramprodukt innefat-
tande ett av en elektronisk styrenhet lasbart varaktigt datalagringsmedium, vilket datalagringsmedium har datorprogrammet lag-rat darpa. Namnda datalagringsmedium är exempelvis ett optiskt datalagringsmedium i form av en CD-ROM-skiva, en DVD-skiva
etc., ett magnetiskt datalagringsmedium i form av en harddisk, en
diskett, ett kassettband etc., eller ett Flashminne eller ett minne av typen ROM, PROM, EPROM eller EEPROM.
Fig. 7 illustrerar mycket schematiskt en elektronisk styrenhet 18
innefattande ett exekveringsmedel 37, sasom en central proces-
sorenhet (CPU), for exekvering av datorprogramvara. Exekveringsmedlet 37 kommunicerar med ett minne 38, exempelvis av typen RAM, via en databuss 39. Styrenheten 18 innefattar aven ett varaktigt datalagringsmedium 40, exempelvis i form av ett Flashminne
eller ett minne av typen ROM, PROM, EPROM eller EEPROM. Exekveringsmedlet 37 kommunicerar med datalagringsmediet 40 via databussen 39. Ett datorprogram innefattande datorprogramkod for implementering av ett forfarande enligt uppfinningen är lagrat pa datalagringsmediet 40.
Uppfinningen är givetvis inte pa nagot satt begransad till de ovan beskrivna utforingsformerna, utan en mangd mojligheter till modifikationer darav torde vara uppenbara for en fackman pa omradet utan att denne for den skull avviker fran uppfinningens ram sadan
denna definieras i bifogade patentkrav.
19
Exempelvis kan det uppfinningsenliga forfarandet utforas pa ett fordon med en kraftaggregatskonfiguration som saknar forbranningsmotor, dvs är rent elektriskt drivet av de !pada elektriska ma-
skinerna. I ett sadant fall skall kraftaggregatskonfigurationen upp-
visa atminstone ett lager av elektrisk energi, men i fallet av forekomst av en forbranningsmotor är det inte nodvandigt att kraftaggregatskonfigurationen uppvisar sadant lager av elektrisk energi.
Det uppfinningsenliga forfarandet skulle kunna utforas pa ett for-
don med ett drivsystem som har planetvaxelns ringhjul som namnda forsta komponent och solhjul som namnda tredje komponent, vilket betyder att den forsta elektriska maskinens rotor skulle vara forbunden med planetvaxelns solhjul och den andra elekt-
riska maskinens rotor och forbranningsmotorn vid forekomst av sa-
dan skulle vara forbunden med planetvaxelns ringhjul istallet for med solhjulet. Med fordel är dock planetvaxelns utgaende axel for overforing av moment for fordonets framdrivning forbunden med planethjulhallaren.
Det är inte heller nadvandigt att den utgaende axeln fran planetvaxeln är en ingaende axel hos en vaxellada, utan fordonet skulle kunna sakna vaxellada.
