Description
25 532 7'l5 REDOGÖRELSE FÖR UPPFINNINGEN Ett syfte med föreliggande uppfinning är att åstadkomma ett förfarande och ett systern som minskar bränsleförbrukningen hos en förbränningsmotor som driver ett motorfordon. DISCLOSURE OF THE INVENTION An object of the present invention is to provide a method and a sister which reduces the fuel consumption of an internal combustion engine which drives a motor vehicle.
I enlighet med föreliggande uppfinning åstadkoms ett förfarande för styming av en växellåda förbunden med en förbränningsmotor som driver ett motorfordon. Först bestäms om ett tillstånd där låg effekt under ett visst tröskelvärde för drivning av fordonet föreligger eller snart kommer att föreligga. Om ett sådant tillstånd föreligger växlas växellådan till en hög växel så att fordonet drivs vid ett varvtal som är under momentplatån för den höga växeln. Härigenom behöver inget bränsle, t ex dieselolja då motom är en dieselmotor, tillföras vid de driftsfall då motom drivs (”släpas”) med den höga växeln ilagd.In accordance with the present invention, there is provided a method of controlling a gearbox connected to an internal combustion engine which drives a motor vehicle. It is first determined whether a condition where low power below a certain threshold value for driving the vehicle exists or will soon exist. If such a condition exists, the gearbox is shifted to a high gear so that the vehicle is driven at a speed which is below the torque plateau of the high gear. As a result, no fuel, eg diesel oil when the engine is a diesel engine, needs to be supplied in the operating cases when the engine is driven ("towed") with the high gear engaged.
I enlighet med en utföringsforrn av uppfinningen används en Look-Ahead (framförhållnings-) funktion för att prediktera när den höga växeln kan läggas i respektive måste läggas ur för att fordonet skall kunna drivas i marschhastighet med minimal bränsletillförsel.According to an embodiment of the invention, a Look-Ahead function is used to predict when the high gear can be engaged and must be disengaged in order for the vehicle to be driven at cruising speed with minimal fuel supply.
Uppfinningen avser också ett fordon och en datorprogramprodukt anordnade att realisera styrningen enligt det ovan beskrivna förfarandet.The invention also relates to a vehicle and a computer program product arranged to realize the control according to the method described above.
Genom att använda förfarandet, fordonet och datorprogramprodukten i enlighet med uppfinningen erhålls lägre parasitfórluster vid drivning av fordonet vilket i sin tur leder till en lägre bränsleförbrukning hos ett fordon drivet av en förbränningsrnotor.By using the method, the vehicle and the computer program product in accordance with the invention, lower parasite losses are obtained when driving the vehicle, which in turn leads to a lower fuel consumption of a vehicle driven by an internal combustion engine.
KORTFATTAD BESKRIVNING AV RITNINGARNA Föreliggande uppfinning kommer nu att beskrivas i närmare med hjälp av icke-begränsande exempel och med hänvisning till de bilagda ritningama, på vilka: 10 15 20 25 532 7'l5 - Fig. 1 är en generell delvy av en av motor, - Fig. 2 är en momentkurva med angivet drifioniråde for en växel, och - Fig. 3 är ett flödesschema som illustrerar steg i stymingen av en motor i ett motorfordon.BRIEF DESCRIPTION OF THE DRAWINGS The present invention will now be described in more detail by means of non-limiting examples and with reference to the accompanying drawings, in which: Fig. 1 is a general partial view of an engine , - Fig. 2 is a torque curve with the specified driving range for a gear, and - Fig. 3 is a flow chart illustrating steps in the steering of an engine in a motor vehicle.
BESKRIVNING AV FÖREDRAGNA UTFÖRINGSFORMER I fig. l visas schematiskt valda delar av en drivlina 100 i ett motorfordon 10. Drivlinan som är avbildad i fig. 1 kan till exempel vara avsedd att ingå i en lastbil eller ett annat tungt fordon, som en buss eller liknande. I drivlinan 100 ingår en motor 101. Motorn är vidare kopplad till en halvautomatisk växellåda 105.DESCRIPTION OF PREFERRED EMBODIMENTS I fi g. 1 schematically shows selected parts of a driveline 100 in a motor vehicle 10. The driveline depicted in fi g. 1 may, for example, be intended to be included in a truck or other heavy vehicle, such as a bus or the like. The driveline 100 includes a motor 101. The motor is further connected to a semi-automatic gearbox 105.
Motorn 101 och växellådan 105 styrs av minst en styrenhet 107, till exempel en elektronisk styrenhet (ECU). Styrenheten är anpassad för att ta emot sensorsignaler från olika delar av fordonet, inklusive växellådan och motorn. Styrenheten 107 är vidare anordnad att leverera styrsignaler till olika delar och komponenter av fordonet, som motorn, inklusive men inte begränsat till styrsignaler för växellåda. Styrenheten 107 är vidare anordnad att mottaga data från en så kallad ”Look ahead” (LA) funktion 103. Look ahead funktionen förser styrenheten med information bland annat om hur vägen frarnfór fordonet ser ut. Till exempel kan information om vägens lutning erhållas via Look ahead funktionen.The motor 101 and the gearbox 105 are controlled by at least one control unit 107, for example an electronic control unit (ECU). The control unit is adapted to receive sensor signals from various parts of the vehicle, including the gearbox and the engine. The control unit 107 is further arranged to supply control signals to various parts and components of the vehicle, such as the engine, including but not limited to gear control signals. The control unit 107 is further arranged to receive data from a so-called "Look ahead" (LA) function 103. The look ahead function provides the control unit with information, among other things, about what the road in front of the vehicle looks like. For example, information about the slope of the road can be obtained via the Look ahead function.
Styrningen av olika delar och komponenter i fordonet och särskilt val av växel styrs av förprogrammerade instruktioner i styrenheten. De förprogrammerade instruktionerna utgörs typiskt av en datorprogramprodukt 109 lagrad på ett digitalt lagringsmedium som ett arbetsminne (RAM), flashminne (EPROM, EEPROM) eller ett läsminne (ROM), och som exekveras av styrenheten. Genom att ändra de förprogrammerade instruktionerna kan fordonets uppträdande i en specifik situation anpassas. 10 l5 20 25 532 'F15 Växellådan l05 i fordonet l0 är försedd med minst en hög växel anordnad att ha ett drifiområde under momentplatån för växeln. Fordonet är således inte körbart med en sådan hög växel ilagd eftersom motorvarvtalet är för lågt för att ge nödvändigt moment i en sådan driftpunkt. Syfiet med en sådan växel är att minimera parasitförluster och därmed bränsleförbrukningen under driñförhållanden då det föreligger ett lågt effektbehov. Om till exempel fordonet framförs på en väg som lutar utför väljs den höga växeln och motorn sparar bränsle samtidigt som motorvarvtalet går ned till mycket lågt värde och sänker ljudnivån från motorn. Om styrenheten förses med data om hur vägen framför fordonet ser ut kan den höga växeln läggas i vid en optimal tidpunkt utan att känna av motorsignaler för att bestämma att ett lågt effektbehov föreligger. Om styrenheten till exempel är ansluten att ta emot data om vägen från en Look-ahead funktion kan data från denna funktion användas för att bestämma när den höga växeln skall läggas i.The control of various parts and components in the vehicle and especially the choice of gear is controlled by pre-programmed instructions in the control unit. The pre-programmed instructions typically consist of a computer program product 109 stored on a digital storage medium such as a working memory (RAM), fl ashm memory (EPROM, EEPROM) or a read only memory (ROM), and which is executed by the control unit. By changing the pre-programmed instructions, the behavior of the vehicle in a specific situation can be adapted. 10 l5 20 25 532 'F15 The gearbox l05 in the vehicle l0 is equipped with at least one high gear arranged to have a drive area below the torque plate for the gear. The vehicle is thus not drivable with such a high gear engaged because the engine speed is too low to provide the necessary torque at such an operating point. The purpose of such a gear is to minimize parasite losses and thus fuel consumption under driñ conditions when there is a low power requirement. For example, if the vehicle is driven on a sloping road, the high gear is selected and the engine saves fuel while the engine speed drops to a very low value and lowers the noise level from the engine. If the control unit is provided with data on what the road in front of the vehicle looks like, the high gear can be engaged at an optimal time without sensing engine signals to determine that there is a low power requirement. For example, if the controller is connected to receive data about the path from a Look-ahead function, data from this function can be used to determine when the high gear should be engaged.
I Fig. 2 visas en momentkurva och driftområde för en hög växel enligt ovan. I fi g. 2 framgår att växeln är avsedd att brukas i en driftpunkt under momentplatån för momentkurvan. Om till exempel fordonet framförs i en marschhastighet av 80 km/h och ett lågt effektbehov föreligger kan den höga växeln väljas och motom sparar bränsle. Motorn kommer nu att arbeta med ett mycket lågt varvtal under momentplatån såsom visat i Fig. 2. När vid ett senare tillfälle effekt behöver tas ur motorn växlar styrenheten ner till en lägre växel.Fig. 2 shows a torque curve and operating range for a high gear as above. In fi g. 2 it appears that the gear unit is intended to be used in an operating point below the torque plateau for the torque curve. If, for example, the vehicle is driven at a cruising speed of 80 km / h and there is a low power requirement, the high gear can be selected and the engine saves fuel. The motor will now operate at a very low speed below the torque plateau as shown in Fig. 2. When at a later time power needs to be taken out of the motor, the control unit shifts down to a lower gear.
I Fig. 3 visas ett flödesschema som visar steg som utförs vid styrning av en motor enligt ovan. Först i ett steg 301 bestäms att ett lågt behov av motoreffekt föreligger. Typiskt kan ett lågt effektbehov bestämmas föreligga om effektbehovet är lägre än ett visst tröskelvärde.Fig. 3 shows a flow chart showing steps performed in controlling a motor as above. Only in a step 301 is it determined that there is a low need for motor power. Typically, a low power requirement can be determined to exist if the power requirement is lower than a certain threshold value.
Tröskelvärdet kan till exempel vara en del av men maximala effekten såsom 10 - 15% av den maximala effekten. Till exempel kan styrsignaler från motom användas för att bestämma att en låg motoreffekt för att driva fordonet för närvarande behövs. I enlighet med en utfóringsform används data om vägen framför fordonet för att bestämma att låg 10 15 20 LT! FU motoreffekt för att driva fordonet för närvarande behövs. Särskilt kan data från en Look- Ahead funktion användas. När det bestämts att låg motoreffekt för drivning av fordonet behövs växlas i ett steg 303 växellådan till en hög växel som ej är körbar, dvs. varvtalet ligger under momentplatån för växeln då fordonet framförs i marschhastighet, till exempel 80 eller 90 krn/h.The threshold value can, for example, be part of the maximum effect, such as 10 - 15% of the maximum effect. For example, control signals from the engine can be used to determine that a low engine power to drive the vehicle is currently needed. In accordance with one embodiment, data on the road in front of the vehicle is used to determine that low 10 15 20 LT! FU engine power to drive the vehicle is currently needed. In particular, data from a Look-Ahead function can be used. When it has been determined that low engine power for driving the vehicle needs to be shifted in one step 303 the gearbox to a high gear which is not drivable, i.e. the speed is below the torque plateau for the gear when the vehicle is driven at cruising speed, for example 80 or 90 krn / h.
Därefter kontrolleras i ett steg 305 kontinuerligt om det föreligger ett behov av driveffekt fiån motorn. Till exempel kan ett gaspådrag från föraren och eller styrsigrialer från motorn användas för att bestämma att ett behov av driveffekt föreligger. Om styrenheten 107 har tillgång till data om vägen kan dessa data användas för att bestämma om behov av driveffekt föreligger eller snart kommer att föreligga. Om det i steg 305 bestäms att driveffekt behövs eller snart kommer att behövas växlas motom ner i ett steg 307, annars fortsätter motom att drivas med den höga växeln ilagd.Thereafter, in a step 305, it is continuously checked if there is a need for drive power from the motor. For example, a throttle from the driver and or control signals from the engine can be used to determine that there is a need for drive power. If the controller 107 has access to data about the road, this data can be used to determine if there is a need for drive power or will soon be there. If in step 305 it is determined that drive power is needed or will soon be needed, the motor is shifted down in a step 307, otherwise the motor continues to be driven with the high gear engaged.
Genom att använda förfarandet, fordonet och datorprogramprodukten såsom beskrivna häri erhålls en lägre bränsleförbrukning hos ett fordon drivet av en förbränningsmotor. Detta beror bland annat på att inget bränsle behöver tillföras fórbränningsmotorn vid de driftsfall då den drivs (”släpas”) vid ett lågt varvtal under moment platån på momentkurvan.By using the method, the vehicle and the computer program product as described herein, a lower fuel consumption of a vehicle powered by an internal combustion engine is obtained. This is partly due to the fact that no fuel needs to be supplied to the internal combustion engine in the operating cases when it is operated ("towed") at a low speed below the torque plateau on the torque curve.
