Description
532 #28 SAMMANFATTNING Syftet med den föreliggande uppfinningen är att tillhandahålla en metod och ett system som möjliggör en förbättrad reglering av motorvarvtalet hos tunga fordon försedda med hydrauliskt drivna enheter. 532 # 28 SUMMARY The object of the present invention is to provide a method and system which enables an improved control of the engine speed of heavy vehicles equipped with hydraulically driven units.
Dessa och andra syften uppnås med den metod, den enhet och det datorprogram som anges i bifogade krav. För att sålunda möjliggöra en effektiv drift av ett motorfordons hydrauliska enheter, framför allt hydrauliskt driven karossutrustning såsom en hydraulisk kran på en lastbil, regleras motorvarvtalet i relation till både ett aktuellt nödvändigt motorvarvtal som motorn erfordrar samt ett motorvarvtal som den hydrauliska enheten erfordrar. Framför allt gäller att motorns börvarvtal kan fastställas som det högsta av de motorvarvtal som erfordras av motom och den hydrauliska enheten eller en motors börvarvtal relaterat därtill.These and other objects are achieved by the method, device, and computer program specified in the appended claims. In order to enable efficient operation of a motor vehicle's hydraulic units, in particular hydraulically driven body equipment such as a hydraulic crane on a truck, the engine speed is regulated in relation to both a current required engine speed required by the engine and an engine speed required by the hydraulic unit. In particular, the engine set speed can be set as the highest of the engine speeds required by the engine and the hydraulic unit or an engine set speed related thereto.
Med hjälp av metoden och enheten i enlighet med den föreliggande uppfinningen erhålls en förbättrad reglering av motorvarvtalet hos ett motorfordon försett med en hydraulisk enhet, till exempel en lastbil försedd med en kran eller en frontlastare eller något annat motorfordon med en motor som driver en hydraulpump som driver en hydraulisk enhet. Eftersom motorvarvtalet som krävs för att driva fordonet övervakas och uppdateras kontinuerligt finns det inget behov av att välja ett onödigt högt motorvarvtal, vilket i sin tur sänker bränsleförbrukningen. Dessutom förbättras arbetsmiljön genom att motorbullret kan hållas på en miniminivå.By means of the method and the unit in accordance with the present invention, an improved control of the engine speed of a motor vehicle equipped with a hydraulic unit is obtained, for example a truck equipped with a crane or a front loader or any other motor vehicle with an engine driving a hydraulic pump which operates a hydraulic unit. Since the engine speed required to drive the vehicle is continuously monitored and updated, there is no need to choose an unnecessarily high engine speed, which in turn lowers fuel consumption. In addition, the working environment is improved by keeping engine noise to a minimum.
KORT BESKRIVNING AV RITNINGARNA Den föreliggande uppfinningen beskrivs nu mer i detalj med hjälp av icke- begränsande exempel ooh med hänvisning till bifogade ritningar, i vilka: 10 20 25 30 532 428 -3- - Fig. 1 är en allmän vy över ett system för reglering av motorvarvtalet hos ett motorfordon försett med hydrauliskt drivna enheter, och - Fig. 2 är ett flödesschema som illustrerar de steg som utförs vid reglering av motorvarvtalet hos ett fordon försett med hydrauliskt drivna enheter.BRIEF DESCRIPTION OF THE DRAWINGS The present invention will now be described in more detail by means of non-limiting examples ooh with reference to the accompanying drawings, in which: Fig. 1 is a general view of a system for control of the engine speed of a motor vehicle equipped with hydraulically driven units, and - Fig. 2 is a d circuit diagram illustrating the steps performed in controlling the engine speed of a vehicle equipped with hydraulically driven units.
DETALJERAD BESKRIVNING Fig.1 visar en vy över ett system 100 för reglering av motorvarvtalet hos en motor 105 som driver ett fordon försett med en hydraulisk enhet 103.DETAILED DESCRIPTION Fig. 1 shows a view of a system 100 for controlling the engine speed of an engine 105 which drives a vehicle equipped with a hydraulic unit 103.
Systemet innefattar en styrmodul 109 för reglering av varvtalet hos motorn 105. Styrmodulen 109 är programmerad för att ta emot styrsignaler i realtid från en motorstyrenhet 107, såsom en elektronisk styrenhet (ECU), vilken genererar signaler relaterade till motoms aktuella driftförhållanden.The system includes a control module 109 for controlling the speed of the motor 105. The control module 109 is programmed to receive real-time control signals from a motor control unit 107, such as an electronic control unit (ECU), which generates signals related to the current operating conditions of the motor.
Styrrnodulen 109 är även ansluten till en styrenhet 111 för reglering av den hydrauliska enheten 103. Styrenheten 111 är anpassad för att styra den hydrauliska enheten i relation till insignaler från en användare som till exempel använder ett manöverdon (ej visat).The control module 109 is also connected to a control unit 111 for controlling the hydraulic unit 103. The control unit 111 is adapted to control the hydraulic unit in relation to input signals from a user using, for example, an actuator (not shown).
Styrmodulen 109 tar emot signaler från styrenheten 111 som anger det för tillfället nödvändiga motorvarvtalet för att driva den hydrauliska enheten 103. l enlighet med ett utförande sänder styrenheten en signal som anger det för tillfället nödvändiga flödet i den hydrauliska enheten 103. l enlighet med ett utförande är hydraulpumpen som driver den hydrauliska enheten en pump med fast kapacitet som inte kan justeras. l ett annat utförande är hydraulpumpen som driver den hydrauliska enheten en tryckkompenserad variabel pump med tryckreglerad kapacitet. Styrrnodulen programmeras då till att omvandla det nödvändiga flödet till ett förinställt motorvarvtal med användande av till exempel en uppslagstabell. I enlighet med ett annat utförande är styrenheten 111 anpassad för att sända ut en signal som anger det nödvändiga motorvarvtalet för det nödvändiga flödet i den hydrauliska enheten. 20 25 532 438 Med hjälp av signalerna från motorstyrenheten 107 och hydraulikstyrenheten 111 ställer styrmodulen kontinuerligt in motorvarvtalet i relation till minst båda signalerna från motorn och den hydrauliska enheten. I enlighet med ett utförande väljs motorvarvtalet till det högsta av de motorvarvtal som anges av signalen fràn motorstyrenheten och signalen från hydraulikstyrenheten.The control module 109 receives signals from the control unit 111 indicating the currently required engine speed to drive the hydraulic unit 103. In accordance with one embodiment, the control unit transmits a signal indicating the currently required i fate in the hydraulic unit 103. in accordance with one embodiment. the hydraulic pump that drives the hydraulic unit is a pump with a fixed capacity that cannot be adjusted. In another embodiment, the hydraulic pump driving the hydraulic unit is a pressure compensated variable pump with pressure controlled capacity. The control module is then programmed to convert the required flow to a preset motor speed using, for example, a look-up table. In accordance with another embodiment, the control unit 111 is adapted to emit a signal indicating the required engine speed for the required fl fate in the hydraulic unit. 532 438 Using the signals from the motor control unit 107 and the hydraulic control unit 111, the control module continuously sets the motor speed in relation to at least both signals from the motor and the hydraulic unit. According to one embodiment, the engine speed is selected to the highest of the engine speeds indicated by the signal from the engine control unit and the signal from the hydraulic control unit.
Om till exempel signalen från motorstyrenheten anger att motorns börvarvtal ska vara 800 varv per minut och det nödvändiga flödet i den hydrauliska enheten anger att motoms börvarvtal ska vara 900 varv per minut, ställer styrmodulen 109 in motorvarvtalet som det högsta av de två, i detta exempel skulle motorvarvtalet ställas in till 900 varv per minut.For example, if the signal from the engine control unit indicates that the engine set speed should be 800 rpm and the required fl fate in the hydraulic unit indicates that the engine set speed should be 900 rpm, the control module 109 sets the engine speed as the higher of the two, in this example the engine speed would be set to 900 rpm.
Fig. 2 visar ett flödesschema som illustrerar några procedursteg som utförs vid reglering av motorvarvtalet hos ett motordrivet fordon försett med en hydraulisk enhet. I steg 201 fastställs först ett motorreglerat motorvarvtal utgående från motorsignaler. Hämäst fastställs i steg 203 ett hydrauliskt reglerat motorvarvtal utgående från det för tillfället nödvändiga flödet i den hydrauliska enheten. Därefter ställs motorns varvtal in på ett värde i relation till de motorvarvtal som fastställs i steg 201 och 203. Framför allt gäller att motoms börvarvtal ställs in som det högsta av de motorvarvtal som fastställs i steg 201 och 203 eller ett värde relaterat till det hösta värdet. Därefter återgår proceduren till steg 201 för att kontinuerligt uppdatera motorns varvtal i steg 207.Fig. 2 shows a flow chart illustrating some procedural steps performed in controlling the engine speed of a motor vehicle equipped with a hydraulic unit. In step 201, a motor-regulated motor speed is first determined on the basis of motor signals. At the top, step 203 determines a hydraulically regulated engine speed based on the currently required fl fate of the hydraulic unit. Thereafter, the engine speed is set to a value in relation to the engine speeds determined in steps 201 and 203. In particular, the engine setpoint speed is set to the highest of the engine speeds determined in steps 201 and 203 or a value related to the maximum value. . Thereafter, the procedure returns to step 201 to continuously update the engine speed in step 207.
Den regleringsmetod som beskrivs häri kan med fördel implementeras med hjälp av en dator och regleralgoritmen kan lagras som programmerade instruktioner i ett datorprogram lagrat i ett digitalt lagringsmedium. 10 532 4.28 -5_ Med hjälp av metoden och systemet som beskrivs häri erhålls en förbättrad reglering av motorvarvtalet hos ett motorfordon försett med en hydraulisk enhet, till exempel en lastbil försedd med en kran eller en frontlastare eller något annat motorfordon med en motor som driver en hydraulpump som driver en hydraulisk enhet. Eftersom motorvarvtalet som krävs för att driva fordonet övervakas och uppdateras kontinuerligt finns det inget behov av att välja ett onödigt högt motorvarvtal, vilket i sin tur sänker bränsleförbrukningen. Dessutom förbättras arbetsmiljön genom att motorbullret kan hållas på en miniminivå.The control method described herein can be advantageously implemented using a computer and the control algorithm can be stored as programmed instructions in a computer program stored in a digital storage medium. 10 532 4.28 -5_ Using the method and system described herein, an improved control of the engine speed of a motor vehicle equipped with a hydraulic unit is obtained, for example, a truck equipped with a crane or a front loader or any other motor vehicle with an engine driving a hydraulic pump that drives a hydraulic unit. Since the engine speed required to drive the vehicle is continuously monitored and updated, there is no need to choose an unnecessarily high engine speed, which in turn lowers fuel consumption. In addition, the working environment is improved by keeping engine noise to a minimum.
