Description

1 Forfarande for att styra en hybriddrivlina, en hybriddrivlina, och ett fordon.
UPPFINNINGENS BAKGRUND OCH KAND TEKNIK Foreliggande uppfinning avser ett forfarande for att styra en hybriddrivlina i ett fordon enligt ingressen till patentkravet 1. Uppfinningen avser ocksa en hybriddrivlina, enligt ingressen till patentkravet 6, vilken innefattar organ anpassade att utfora styrningen av forfarandet. Uppfinningen avser ocksa ett fordon enligt ingressen till patentkravet 7, vilket innefattar en sadan hybriddrivlina.
Det farekommer att lastbilar är farsedda med en transmission av bade automatisk och manuell typ. pa denna typ av transmission utfors en vaxling fran en forsta vaxel till en andra vaxel genom att fran ett momenttillstand i drivlinan forsatta vaxelladan i ett momentlost tillstand, darefter lagga ur nuvarande vaxel, darefter synkronisera in- gaende axels varvtal och sidoaxelns varvtal till varvtalet motsvarande den andra vaxeln. Darefter ilaggs den andra vaxeln, varefter vaxelladan forsatts i ett av foraren begart drivlinemomenttillstand.
Fordonet kan drivas av en forbranningsmotor och en elmaskin, vilka samverkar for att avge onskad effekt och for att bland annat erhalla en god bransleekonomi hos fordonet. Elmaskinen kan vid acceleration och konstant hastighet hos fordonet fungera som elmotor. Vid retardation av fordonet kan elmaskinen fungera som en generator och utova ett bromsande moment pa fordonets drivlina.
I drivlinan forekommer glapp mellan de i transmissionen samverkande komponenterna, vilka glapp uppkommer av exempelvis kuggspel mellan kugghjul i ingrepp. Det forekommer ocksa en torsionsfjadrande effekt hos de roterbara axlar som finns i drivlinan. Glappet och den torsionsfjadrande effekten blir som mest pataglig nar vaxella- dan forsatts i ett drivlinemomenttillstand Iran ett momentlost tillstand. For det fall el- maskinen kraftigt accelereras eller retarderas efter det att den andra vaxeln ilagts kommer namnda glapp och fjadrande axlar att medfora en puls och stOtvag i hybriddrivlinan, vilken kommer att upplevas som storande for forare och passagerare i fordonet. Pulsen och stotvagen kan ocksa framkalla en svangning i hybriddrivlinan pa 2 grund av den torsionsfjadrande effekten hos axlarna. Denna svangning kommer ocksa upplevas okomfortabel av fordonets forare och passagerare.
Efter det att den andra vaxeln ilagts och moment skall tillforas transmissionen finns ingen garanti att fOrbranningsmotorn drivs vid det varvtal som kravs for att kunna kopplas in och tillfora moment till transmissionen. Darmed atgar tid for att styra forbranningsmotorn till Onskat varvtal och moment.
Dokumentet WO 2011141233, Al visar ett fordon, som är fat-sett med en hybriddriv- lina, som innefattar en forbranningsmotor och en elmaskin. Vid vaxling anvands el- maskinens troghetsmoment for synkronisering. Darmed kan synkroniseringsringar i vaxelladan elimineras.
SAMMANFATTNING AV UPPFINNINGEN Trots kanda losningar finns ett behov att vidareutveckla en hybriddrivlina som ger god akkomfort i fordonet vid vaxling, som uppvisar kort vaxlingstid och som kompenserar for en bristfalligt skattad kontaktpunkt mellan kopplingsdelar hos kopplingsanordningen vid inkopplingen av forbranningsmotorn.
Syftet med foreliggande uppfinning är saledes att tillhandahalla en hybriddrivlina som ger god akkomfort i fordonet vid vaxling.
Ett ytterligare syfte med uppfinningen är att tillhandahalla en hybriddrivlina som upp- visar kort vaxlingstid.
Annu ett syfte med uppfinningen är att tillhandahalla en hybriddrivlina som kompenserar for en bristfalligt skattad kontaktpunkt mellan kopplingsdelar hos kopplingsanordningen vid inkoppling av forbranningsmotorn till hybriddrivlinan.
Dessa syften uppnas med ett forfarande for att styra en hybriddrivlina i ett fordon av det inledningsvis namnda slaget, vilken kannetecknas av de sardrag som anges i patentkravet 1. 3 En sadan hybriddrivlina kommer att ge god akkomfort vid vaxling for forare och passagerare i fordonet. Genom att reglera elmaskinens acceleration eller retardation och detektera en styrsignal for nar elmaskinen nar eller overstiger en forutbestamd momentniva kan en puls och stotvag i hybriddrivlinan undvikas, vilket medfor att akkom- forten i fordonet akar.
Enligt en utfaringsform regleras elmaskinens acceleration och moment. Detta medfOr att forekommande glapp och torsionsfjadringseffekter i drivlinan tas om hand och utjamnas, vilket medfOr att en puls och stOtvag i hybriddrivlinan undviks, sá att akkom- forten i fordonet okar.
Enligt annu en utforingsform inkopplas forbranningsmotorn nar ett forutbestamt momentet hos elmaskinen uppnatts, eller nar ett for elmaskinen maximalt moment uppnatts om det for elmaskinen maximala momentet är lagre an det forutbestamda mo- mentet. Eftersom kopplingsanordningen stangs och forbranningsmotorn inkopplas forst nar glapp och torsionsfjadringsvag i drivlinan uppvridits erhalls en kompensation for en bristfalligt skattad kontaktpunkt mellan kopplingsanordningens kopplingsdelar. Detta ger en robusthet och mjuk inkoppling av forbranningsmotorn.
Enligt annu en utforingsform frankopplas forbranningsmotorn fran den ingaende ax- eln medelst kopplingsanordningen fore det att vaxling sker. Hybriddrivlinan kommer darvid att uppvisa en lag vaxlingstid.
Ovan angivna syften uppnas aven med en hybriddrivlina av det inledningsvis namn25 da slaget, vilken kannetecknas av de sardrag som anges i patentkravet 6, samt av ett fordon av det inledningsvis namnda slaget, vilket kannetecknas av de sardrag som anges i patentkravet 7.
Ytterligare fordelar med uppfinningen framgar av fOljande detaljerade beskrivning. 4 KORT BESKRIVNING AV RITNINGARNA I det foljande beskrivs, sasom ett exempel, foredragna utforingsformer av uppfin- ningen med hanvisning till bifogade ritningar, pa vilka: Fig. 1 visar i en sidovy ett schematiskt visat fordon med en drivlina enligt fOreliggande uppfinning, Fig. 2 visar i en sidovy en schematiskt visad drivlina enligt foreliggande uppfinning, Fig. 3 visar ett diagram over varvtal och moment vid forfarandet for att styra hybriddrivlinan enligt foreliggande uppfinning, och Fig. 4 visar ett flodesschema Over forfarandet for att styra hybriddrivlinan enligt fore- liggande uppfinning.
DETALJERAD BESKRIVNING AV FOREDRAGNA UTFORINGSFORMER AV UPPFINNINGEN Fig. 1 visar en schematisk sidovy av ett fordon 1, som innefattar en hybriddrivlina 2 med en forbranningsmotor 3 och en elmaskin 4, vilka är kopplade till en vaxellada 6. Vaxelladan 6 är vidare kopplad till fordonets 1 drivhjul 8.
Fig. 2 visar schematiskt en hybriddrivlina 2, som innefattar forbranningsmotorn 3 och elmaskinen 4, vilka är kopplade till en ingaende axel 10 hos vaxelladan 6. Fbrbranningsmotorn 3 kan till och frankopplas den ingaende axeln 10 medelst en kopplingsanordning 12, som kan vara manuellt och/eller automatiskt manovrerbar. Vaxelladan 6 är foretradesvis en kombinerad manuell och automatisk vaxellada 6 av splittyp och innefattar aven en huvudaxel 14, en sidoaxel 16 och en utgaende axel 18 pa vilka ett eller flera kugghjul 20 är anordnade. Mellan huvudaxeln 14 och den utgaende axeln 18 är en retarder 22 anordnad. Den utgaende axeln 18 är kopplad till en slutvaxel 24, som i sin tur är kopplad till fordonets 1 drivhjul 8. En elektronisk styrenhet 26 är kopplad till forbranningsmotorn 3, kopplingsanordningen 12, elmaskinen 4 och vaxelladan 6 medelst elektriska ledare 28. lstallet for att overfora signaler genom de elektriska ledarna 28 kan signaler mellan den elektroniska styrenheten 26 och forbranningsmotorn 3, kopplingsanordningen 12, elmaskinen 4 samt vaxelladan 6 overforas tradlost. Den elektroniska styrenheten 26 kan innefatta ett minne M och ett datorprogram P.
Det är ocksa mojligt att koppla en dator 30 till styrenheten 26.
Fig. 3 visar ett diagram Over varvtal och moment vid fOrfarandet fbr att styra hybriddrivlinan 2 enligt foreliggande uppfinning. Den ovre heldragna kurvan representerar elmaskinens 4 varvtal Ne vid en forsta vaxel. Den streckade kurvan representerar elmaskinens 4 varvtal Ng vid en andra vaxel. Saledes representerar diagrammet i fig. 3 en uppvaxling. I fig. 3 visas ocksa elmaskinens 4 vridmoment Te och forbranningsmotorns 3 vridmoment Tc. Vid tidpunkten ti drivs fordonet 1 av elmaskinen 4 med varvtalet Ni och av forbranningsmotorn 3 vid den forsta vaxeln. For att genomfora ett vaxlingsforlopp fran den forsta till den andra vaxeln frankopplas forbran- ningsmotorn 3 den ingaende axeln 10 hos vaxelladan 6 medelst kopplingsanord- ningen 12 vid tidpunkten t2. Dessforinnan har, mellan tidpunkterna ti och t2 forbranningsmotorns 3 moment rampats ner till noll, vilket intraffar vid t2, varefter ett momentlost tillstand mellan sidoaxeln 16 och huvudaxeln 14 skapas med hjalp av elmaskinen 4, vilket intraffar vid tidpunkten t3. Nar ett momentlost tillstand skapats laggs den forsta vaxeln ur vid t3, sá att vaxelladan 6 intager ett neutrallage. Darefter inleds en synkroniseringsfas dar varvtalet hos elmaskinen 4 mellan tidpunkterna t3 och t4 minskas mot N2. Nar elmaskinens varvtal natt varvtalet N2, vilket sker vid tidpunkten t4, kommer den andra vaxelns kugghjul pa huvudaxeln intaga samma varvtal som huvudaxeln, varpa den andra vaxelns kugghjul forbinds med huvudaxeln. Den andra vaxelns ilaggning sker saledes vid tidpunkten t4.
Urlaggning av den forsta vaxeln, synkroniseringen samt ilaggningen av av den andra vaxeln sker i vaxelladan 6 och styrs av den elektroniska styrenheten 26. Ett antal varvtalsgivare och organ for att avkanna moment (inte visade) finns anordnade vid hybriddrivlinan 2 for att ge information om varvtal och moment hos forbranningsmo- torn 3, kopplingsanordningen 12, elmaskinen 4 samt de i vaxelladan 6 roterade komponenterna. 6 Nar den andra vaxeln är ilagd är elmaskinen 4 sammankopplad med fordonets 1 drivhjul 8 via vaxelladan 6 och slutvaxeln 24. I vaxelladan 6 och slutvaxeln 24 forekommer glapp mellan de i vaxelladan 6 och slutvaxeln 24 samverkande komponenterna, exempelvis kuggspel mellan kugghjul 20 i ingrepp. Det forekommer ocksa en torsionsfjadrande effekt has de roterbara axlar som finns i vaxelladan 6 och slutvax- eln 24 samt has axlar som sammankopplar vaxelladan 6, slutvaxeln 24 och drivhjulen 8, sasom kardan- och drivaxlar. Far det fall elmaskinen 4 kraftigt accelereras efter det att den andra vaxeln ilagts kommer namnda glapp och fjadrande axlar att medfora en puls och statvag i hybriddrivlinan 2, vilken kommer att upplevas som starande for forare och passagerare i fordonet 1. Pulsen och stotvagen kommer ocksa att framkalla en svangning i hybriddrivlinan 2 pa grund av den torsionsfjadrande effekten has axlarna. Denna svangning kommer ocksa upplevas okomfortabel av fordonets 1 forare och passagerare.
Genom att reglera elmaskinens 4 moment med en styrsignal enligt det uppfinnings- enliga forfarandet erhalles ett begransat moment, sá att en puls och stotvag i hybriddrivlinan 2 undviks, vilket medfor att de negativa effekterna som beskrivs ovan elimineras. Saledes accelereras elmaskinen 4 med ett begransat moment medelst styrenheten 26 efter det att den andra vaxeln lagts i vid t4. Under en tidsperiod mellan t4 och t5 kommer elmaskinens 4 varvtal och moment att aka utan att nagot namnvart moment kommer att overforas till fordonets 1 drivhjul 8 pa grund av glapp och torsionsfjadring i drivlinan 2.
Styrsignalen som reglerar momentet till elmaskinen 4 kan beskrivas som: Te req = Je X thw + re - tie X the ± Offset[ 1 ] re req avser det begarda momentet till elmaskinen 4 motsvarar troghetsmomentet has elmaskinen 4. thw motsvarar acceleration has fordonets ldrivhjul 8. re motsvarar vridmoment fran elmaskinen 4. 7 doe motsvarar elmaskinens 4 acceleration.
Offset motsvarar ett forutbestamt varde for elmaskinaccelerationen. Ju lagre offsetvarde desto langre blir tiden for att upptaga glappet i drivlinan.
Vid t5 nas ett tillstand dá glapp upptagits av elmaskinens 4 varvtal. Darefter retarde- rar elmaskinen 4, varvid den delen av styrsignalen som representerar -Je x (be kommer att ge ett positivt tillskott till styrsignalen. Nar styrsignalen overstiger ett visst forutbestamt varde, vilket i fig. 3 sker vid tidpunkten t6, anses glappet i drivlinan vara eliminerat.
Ju storre glapp och torsionsfjadringsvag som forekommer i hybriddrivlinan 2, desto langre blir tidsperioden mellan t4 och t6. Tidsperioden mellan t4 och t6 paverkas av Offset-vardet, vilket kan farutbestammas eller momentant bestammas medelst en aterkopplingsfunktion till styrenheten 26. For det fall Offset-vardet forutbestams base- ras forutbestamningen pa erfarenhetsmassiga varden fOr glappets och torsionsfjad- ringsvagens storlek och den tid det tar att utjamna glappet och torsionsfjadringsvagen.
Nar styrsignalen till elmaskinen 4 nar ett forutbestamt signalvarde, som motsvarar det forutbestamda momentet for eliminerat glapp i drivlinan okas momentet till ett be- gart moment som foretradesvis valjs av en forare i fordonet 1. Darmed kommer fordonet 1 att paverkas med ett onskat moment. For det fall elmaskinen 4 nar sin begransning vad betraffar varvtal och/eller moment eller nar en viss kalibrerbar momentniva tillkopplas forbranningsmotorn 3 den ingaende axeln 10 genom att aktivera och stanga kopplingsanordningen 12, vilket sker vid t7. Eftersom kopplingsanord- ningen 12 stangs nar glapp och torsionsfjadringsvag i drivlinan 2 uppvridits erhalls en kompensation for en bristfalligt skattad kontaktpunkt mellan kopplingsanordningens 12 kopplingsdelar. Detta ger en robusthet och mjuk inkoppling av forbranningsmotorn 3. Nar forbranningsmotorn 3 tillkopplats kan elmaskinens 4 avgivna moment styras till ett forutbestamt malmoment utgaende fran en lamplig driftstrategi samtidigt som ett avtagande moment fran elmaskinen 4 kan kompenseras med momentet fran forbranningsmotorn 3 och anpassas till det moment som fOraren begar, vilket sker vid t8. 8 Fig. 3 representerar en uppvaxling fran en forsta vaxel till en andra vaxel. Uppfinningen är ocksa tillampbar vid en nedvaxling fran en andra till en forsta vaxel.
Fig. 4 visar ett flOdesschema over forfarandet fOr att styra hybriddrivlinan 2 enligt fa- religgande uppfinning. Forfarandet innefattar foljande steg: styr vaxelladan 6 till ett neutrallage; reglera varvtalet hos elmaskinen 4 till ett forutbestamt varvtal, som motsvarar ett malvarvtal kir den ingaende axeln 10 enligt nastkommande valda utvaxling; c) lagg i en vaxel i vaxelladan 6; reglera elmaskinen 4, sá att elmaskinen 4 accelereras eller retarderas beroende pa ett begart drivmoment for fordonet 1; detektera nar en styrsignal for elmaskinen 4 motsvarar ett forutbestamt signalvarde; och f) reglera elmaskinen 4 till det begarda drivmomentet.
Malvarvtalet has den ingaende axeln 10 styrs av vald vaxel i vaxelladan 6 och kan beraknas genom utvaxlingsforhallandet mellan den ingaende axeln 10 och den utgaende axeln 18 for den valda vaxeln. Saledes kan den ingaende axelns 10 varvtal be- raknas som ett malvarvtal innan den nya vaxeln ilaggs.
Under steget d) ovan accelereras eller retarderas elmaskinen 4 beroende pa am det begarda drivmomentet for fordonet 1 är positivt eller negativt, det vill saga am det begarda drivmomentet for fordonet lhar positivt eller negativt tecken.
I steg d) kan elmaskinen 4 enligt ett utfOrande regleras med en farutbestamd momentbegransning. Under en tidsperiod i steget d) kommer elmaskinen 4 accelerera eller retardera utan att nagot namnvart moment kommer att overforas till fordonets 1 drivhjul 8 pa grund av glapp och torsionsfjadring i drivlinan 2. Genom att reglera el- motorn med en forutbestamd momentbegransning undviks en puls och stotvag i driv- linan.
Genom att i steget e) detektera nar en styrsignal for elmaskinen 4 motsvarar ett forutbestamt signalvarde med avsende pa elmaskinens 4 moment kan eventuella glapp 9 och forekommen torsionsfjadring i drivlinan beaktas. Nar styrsignalen overstiger ett visst forutbestamt varde anses glapp och torsionsfjadring i drivlinan vara eliminerat, varvid en puls och stotvag i drivlinan undviks.
FOre steget a) kan enligt ett utforande g) forbranningsmotorn 3 frankopplas fran den ingaende axeln 10 medelst en kopplingsanordning 12. Forbranningsmotorn 3 är dá frankopplad drivlinan.
