Description

1 Forfarande for att bromsa ett fordon med en hybriddrivlina, en hybriddrivlina och ett fordon, innefattande en sadan hybriddrivlina.
UPPFINNINGENS BAKGRUND OCH KAND TEKNIK Foreliggande uppfinning avser ett forfarande for att bromsa ett fordon med en hybriddrivlina enligt ingressen till patentkravet 1. Uppfinningen avser ocksa en hybriddrivlina enligt ingressen till patentkravet 12 och ett fordon enligt ingressen till patent- kravet 13, innefattande en sadan hybriddrivlina.
Ett hybriddrivet fordon drivs 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 ocksa anvandas for att bromsa fordonet, varvid elma- skinen fungerar som en generator och darmed aterfOr energi till en elektrisk ackumu- lator i fordonet. Fordonet är ocksa forsett med en transmission for att fordela kraft fran forbranningsmotorn och elmaskinen samt for att astadkomma lamplig utvaxling till fordonets drivhjul.
I fordonets drivlina forekommer glapp mellan de i transmissionen samverkande kom- ponenterna, 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 pataglig markbart for passagerare i fordonet nar elmaskinen anvands for att retardera fordonet vid in- bromsning och nar elmaskinen anvands som drivmotor efter att inbromsning upphort.
Vid inbromsning och efterfoljande upphorande av bromsning kommer elmaskinens vridmoment pa grund av namnda glapp och fjadrande axlar att astadkomma en puls och stOtvag i hybriddrivlinan, vilken kommer att upplevas som stOrande kir farare och passagerare i fordonet. Pulsen och stotvagen kan ocksa framkalla en svangning i hybriddrivlinan pa grund av den torsionsfjadrande effekten hos axlarna. Denna svangning kommer ocksa upplevas okomfortabel av fordonets forare och passagera- re. 2 Dokumentet DE102011101487 visar ett fordon, som är forsett med en hybriddrivlina, som innefattar en forbranningsmotor och en elmaskin. Vid inbromsning anvands elmaskinen som generator for att bromsa fordonet.
SAMMANFATTNING AV UPPFINNINGEN Trots kanda losningar finns ett behov att vidareutveckla en hybriddrivlina som ger god akkomfort i fordonet vid inbromsning och nar inbromsning upphar.
Syftet med foreliggande uppfinning är saledes att tillhandahalla en hybriddrivlina som ger god akkomfort i fordonet vid inbromsning och nar inbromsning upphOr.
Detta syfte uppnas med ett fOrfarande for att bromsa ett fordon med en hybriddrivlina enligt det inledningsvis namnda slaget, vilket kannetecknas av de sardrag som anges i patentkravet 1.
En sadan hybriddrivlina kommer att ge god akkomfort for forare och passagerare vid inbromsning och nar inbromsning upphor. Genom att styra elmaskinen med en forut- bestamd momentbegransning vid inbromsning och nar inbromsning upphor kan forekommande glapp och torsionsfjadringseffekter i drivlinan tas am hand och utjamnas, vilket medfor att en puls och stotvag i hybriddrivlinan undviks, vilket medfor att akkomforten i fordonet akar.
Enligt en ytterligare utforingsform okas momentet hos elmaskinen stegvis under mo- mentbegransningen. Detta medfar att fOrekommande glapp och torsionsfjadringseffekter i drivlinan tas am hand och utjamnas, vilket medfor att en puls och stotvag i hybriddrivlinan undviks, sä att akkomforten i fordonet akar.
Ovan angivna syften uppnas aven med en hybriddrivlina av det inledningsvis namn- da slaget, vilket kannetecknas av de sardrag som anges i patentkravet 12, samt av ett fordon av det inledningsvis namnda slaget, vilket kannetecknas av de sardrag som anges i patentkravet 13. 3 Ytterligare fordelar med uppfinningen framgar av foljande detaljerade beskrivning.
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 diagram over bromspedalsposition och moment vid forfarandet for att for att bromsa fordonet med hybriddrivlinan enligt foreliggande uppfinning, och Fig. 4 visar ett flodesschema Over forfarandet for att bromsa fordonet med hybriddrivlinan enligt foreliggande uppfinning.
DETALJERAD BESKRIVNING AV FOREDRAGNA UTFORINGSFORMER AV UPP20 FINNINGEN 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. Drivhjulen 8 är forsedda med hjulbromsar 9.
Fig. 2 visar schematiskt en hybriddrivlina 2, som innefattar forbranningsmotorn 3 och elmaskinen 4, vilka är kopplade till en ingaende axel 10 has vaxelladan 6. Forbranningsmotorn 3 kan till och frankopplas den ingaende axeln 10 medelst en kopplings- anordning 12, som kan vara manuellt och/eller automatiskt manovrerbar. Vaxelladan 6 kan vara en godtycklig vaxellada 6, men 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. MeIlan huvudaxeln 14 och den utgaende axeln 18 är en retarder 22 anordnad. Den 4 utgaende axeln 18 är kopplad till en slutvaxel 24, som i sin tur är kopplad till fordo-nets 1 drivhjul 8, som är forsedda med hjulbromsar 9. En elektronisk styrenhet 26 är kopplad till forbranningsmotorn 3, kopplingsanordningen 12, elmaskinen 4, vaxelladan 6 och hjulbromsarna 9 medelst elektriska ledare 28. En bromspedal 29 är kopp- lad till styrenheten far att paverka elmaskinen 4 och hjulbromsarna 9. lstallet for att overfora signaler genom de elektriska ledarna 28 kan signaler mellan den elektroniska styrenheten 26 och farbranningsmotorn 3, kopplingsanordningen 12, elmaskinen 4, vaxelladan 6, hjulbromsarna 9 och bromspedalen 29 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 bromspedalsposition och moment vid forfarandet for att styra hybriddrivlinan 2 enligt foreliggande uppfinning. Den ovre heldragna kurvan representerar bromspedalens 29 position. Den nedre heldragna kurvan representerar elmaskinens 4 moment vid inbromsning av fordonet 1.
Vid tidpunkten t1 trycker fordonets 1 forare pa bromspedalen 29, som darmed fors fran en forsta position D1 mot en andra position D2. Enligt fig. 3 nar bromspedalen positionen D2 vid tidpunkten t2. Nar bromspedalen 29 aktiveras genom att den trycks ner och fors fran positionen D1 frankopplas forbranningsmotorn 3 den ingaende ax- eln 10 has vaxelladan 6 medelst kopplingsanordningen 12, vilket sker vid tidpunkten t1. For det fall bromspedalspositionen i den andra positionen D2 eller bromspedalens acceleration nar den lamnar positionen D1 motsvarar en mycket kraftig inbromsning aktiveras fordonets 1 hjulbromsar 9. Vid nedtryckningen och darmed aktiveringen av bromspedalen 29 vid tidpunkten t1 omkopplas aven elmaskinen 4 till generatordrift far att pabarja bromsning och tillsammans med hjulbromsarna 9 ytterligare bidraga till inbromsning av fordonet 1 medelst ett fran elmaskinen 4 verkande bromsmoment pa drivlinan 2. Samtidigt som bromspedalen 29 aktiveras vid tidpunkten t1 skickas en signal Iran styrenenheten 26 till elmaskinen 4. Nar det star klart att bromspedalen 29 aktiveras med en acceleration och/eller en kraft, som overstiger ett forutbestamt gransvarde eller alternativt nar bromspedalen 29 farts till en viss position motsvarande positionen D2, kommer aven fordonets 1 hjulbromsar 9 att aktiveras.
For det fall bromspedalen 29 aktiveras med en acceleration och/eller en kraft som understiger ett forutbestamt gransvarde eller alternativt att bromspedalspositionen i den andra positionen D2 motsvarar en mjuk inbromsning kommer enbart elmaskinen 4 aktiveras genom att omkopplas till generatordrift for att bromsa fordonet 1 medelst ett pa drivlinan 2 verkande bromsmoment. For det fall bromsmomentet fran elmaski- nen 4 är tillrackligt for att inbromsa fordonet 1 aktiveras inte fordonets 1 hjulbromsar 9. Vid bromspedalens 29 position D1 är det bromsande momentet TO fran elmaskinen 4 vasentligen obefintligt eller noll.
I vaxelladan 6 och slutvaxeln 24 forekommer glapp mellan de i vaxelladan 6 och slut- vaxeln 24 samverkande komponenterna, exempelvis kuggspel mellan kugghjul 20 i ingrepp. Det forekommer ocksa en torsionsfjadrande effekt hos de roterbara axlar som finns i vaxelladan 6 och slutvaxeln 24 samt hos axlar som sammankopplar vaxelladan 6, slutvaxeln 24 och drivhjulen 8, sasom kardan- och drivaxlar. For det fall elmaskinen 4 utverkar ett kraftigt bromsmoment vid omkopplingen till generatordrift kommer namnda glapp och fjadrande axlar att medfora en puls och stotvag i hybriddrivlinan 2, vilken kommer att upplevas som storande 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 hos axlarna. Denna svangning kommer ocksa upplevas okomfortabel av fordonets 1 forare och passagerare.
Genom att styra elmaskinen 4 med en forutbestamd momentbegransning och/eller gradvis Oka elmaskinens 4 moment under tidsperioden t1—t3 for att undvika att en puls och stotvag i hybriddrivlinan 2 uppkommer kan de negativa effekterna som be- skrivs ovan elimineras. Saledes momentbegransas elmaskinen 4 under kontrollerade former medelst styrenheten 26 efter det att inbromsningen pabarjats vid t1. Detta innebar att under tidsperioden mellan t1 och t3 kommer elmaskinens 4 moment att Oka utan att nagot namnvart moment kommer att overforas till fordonets 1 drivhjul 8 pa grund av att glapp och torsionsfjadring i drivlinan 2 upptas av det begransade mo- mentet hos elmaskinen 4. Vid t3 nas ett moment Ti dá glapp och torsionsfjadring i drivlinan 2 upptagits av elmaskinens 4 moment, varvid elmaskinens 4 momentbegransning upphor. Elmaskinens 4 moment kommer darvid kraftigt aka fran momentet Ti under en period mellan t3 och t4 for att darefter ater begransas vid ett uppnatt moment 12, som upptrader strax fore ett moment 13 nas, vilket motsvarar bromspe- 6 dalens 29 andra position D2. Nar tidpunkten t5 natts bromsas fordonet med det moment som foraren begart nar bromspedalen 29 tryckts ned.
Momentbegransningen och tidsperioden mellan t1 och t3 styrs av den elektroniska styrenheten 26. Tidpunkten t4 som intraffar strax fOre ett moment T3 nas detekteras och styrs av styrenheten 26. Ett antal varvtalsgivare och organ for att bestamma moment (inte visade) finns anordnade vid hybriddrivlinan 2 fOr att ge information om varvtal och moment hos forbranningsmotorn 3, kopplingsanordningen 12, elmaskinen 4 samt de i vaxelladan 6 roterade komponenterna.
Glappet och torsionsfjadringen i drivlinan 2 som styrs ut av det begransade momentet fran elmaskinen 4 kan beskrivas med ekvationen: re req = Je x thw + re - Je x the ± Offset[ 1 ] re req avser det begarda momentet till elmaskinen 4 Je motsvarar troghetsmomentet hos elmaskinen 4. thw motsvarar acceleration hos fordonets 1 drivhjul 8. Te motsvarar vridmoment Iran elmaskinen 4. 60e motsvarar elmaskinens 4 acceleration.
Offset motsvarar ett forutbestamt varde for elmaskinaccelerationen. Ju lagre offsetvarde desto langre blir tiden for att upptaga glappet i drivlinan.
Ju storre glapp och torsionsfjadringsvag som forekommer i hybriddrivlinan 2, desto langre blir tidsperioden mellan t1 och t3 samt mellan t4 och t5. Tidsperioden mellan t1 och t3 paverkas av Offset-vardet, vilket kan forutbestammas eller momentant bestammas medelst en aterkopplingsfunktion till styrenheten 26. For det fall Offsetvardet forutbestams baseras forutbestamningen pa erfarenhetsmassiga varden kir glappets och torsionsfjadringsvagens storlek och den tid det tar att utjamna glappet och torsionsfjadringsvagen. 7 Vid tidpunkten t7 manovrerar foraren bromspedalen 29 fran den andra till den forsta positionen D1 for att darmed avsluta bromsningen av fordonet 1. For att inte en puls eller stot skall uppkomma nar elmaskinens 4 moment upphor styrs elmaskinen 4 pa sa vis att momentet minskas med en forutbestamd momentbegransning. Under en tidsperiod motsvarande t6-t7 minskas momentet fran T3 till T2. Darefter styrs elma- skinen 4 utan momentbegransning mot ett moment som motsvarar bromspedalens 29 fOrsta position Dl. Fbr att undvika en puls eller stbt i drivlinan 2 nar elmaskinens 4 moment helt upphor styrs elmaskinen 4 till ett tillstand vid tidpunkten t8 med en forutbestamd momentbegransning innan momentet som motsvarar bromspedalens 29 forsta position D1 nas vid tidpunkten t9. Momentet hos elmaskinen 4 kan stegvis minskas under momentbegransningen nar bromsningen av fordonet 1 avslutas. FOretradesvis utfors momentbegransningen under en forutbestamd tidsperiod, som baseras pa erfarenhetsmassiga varden.
