Description
537 574 LASTKANNANDE ELEMENT, FORFARANDE OCH BERAKNINGSENHET I FORDON TEKNISKT OMRADE Detta dokument beskriver ett lastkannande element, en berakningsenhet och ett farfarande. Narmare bestamt beskrivs ett lastkannande element innefattat i en lastbarande fordonskomponent som ingar i en forbindelse mellan hjulaxel och chassi p fordonet. TECHNICAL FIELD This document describes a load-scanning element, a calculating unit and a procedure. More specifically, a load-sensing element is described included in a load-bearing vehicle component which forms a connection between the wheel axle and the chassis of the vehicle.
BAKGRUND I ett fordon, kanske sarskilt ett fordon som ibland ken- med last av olika vikt och volym, sa10 som exempelvis en lastbil, en langtradare, en buss eller liknande, är det ofta onskvart att fâ en uppskattning av fordonets aktuella totalvikt inklusive last. BACKGROUND In a vehicle, perhaps especially a vehicle that sometimes has a load of different weights and volumes, such as a truck, a truck, a bus or the like, it is often difficult to get an estimate of the vehicle's current total weight including load.
Denna viktuppskattning kan anvandas far ett flertal olika berakningar i fordonet, exempelvis for att berakna bransleforbrukning, bromsstracka eller lampligt lufttryck i fordonets 15 Viktmatning av fordonet kan aven anvandas exempelvis far att varna foraren far att kara pa vagar/ broar dar den hogsta tillatna vikten overskrids, exempelvis. Darmed kan olyckor undvikas genom en korrekt och aktuell viktbestamning av fordonet och dess last. This weight estimate can also be used for a number of different calculations in the vehicle, for example to calculate fuel consumption, braking distance or lamp air pressure in the vehicle. for example. Thus, accidents can be avoided by a correct and current weight determination of the vehicle and its load.
Ett flertal olika matsystem/ vagsystem har utvecklats for dells andarnal. Dessa bygger ex- empelvis pa flagon av foljande tekniker som exempelvis: vinkelgivare med lankage eller liknande for att mats avstandet mellan axel och chassi; vinkelgivare for att mats fjaderns uttojning eller avstandet mellan axel och chassi; tradtojningsgivare som limmas eller skruvas pa chassikomponenter; lastceller mellan chassi och pabyggnad och/ eller lastceller mellan chassi och pabyggnad i kombination med tryckgivare i hydraulcylinder. A number of different food systems / weighing systems have been developed for dells andarnal. These are based, for example, on flakes of the following techniques, such as: angle sensors with a lance or the like to measure the distance between the axle and the chassis; angle sensors for feeding the extension of the spring or the distance between the axle and the chassis; wire strain gauges glued or screwed onto chassis components; load cells between chassis and superstructure and / or load cells between chassis and superstructure in combination with pressure sensor in hydraulic cylinder.
Problemet med de tre forstnamnda teknikerna ovan är att dessa gar ut pa att mata pa en fordonskomponent som är designed for att vara en chassikomponent med de krav p livslangd och hallbarhet som är nadvandiga for denna, men daremot inte noggrannhet vad galler tajning och deformation. Ofta kan det forekomma i detta sammanhang stora tillverk- soDessa stora toleranser medfor att det blir i princip omojligt att installera dessa vagsystem utan att kalibrera vale individ, vilket är tidskravande och darmed dyrt. En annan tankbar &fling är att tillverka ovan namnda chassikomponenter med hogre tillverkningstolerans. Detta blir dock mycket dyrt, och fyller knappast nagon annan funktion, utOver just att majliggara matning av fordonets lastvikt. The problem with the three first-mentioned techniques above is that they involve feeding on a vehicle component that is designed to be a chassis component with the longevity and durability requirements that are necessary for it, but not accuracy in terms of elongation and deformation. In this context, large manufacturing tolerances can often occur. These large tolerances mean that it becomes in principle impossible to install these weighing systems without calibrating the selected individual, which is time-consuming and therefore expensive. Another tankable & flake is to manufacture the above-mentioned chassis components with higher manufacturing tolerance. However, this becomes very expensive, and hardly fulfills any other function, apart from just feeding the vehicle's load weight.
Ett problem med de tva senare metoderna namnda ovan, vilka innefattar lastceller mellan chassi och pabyggnad är att dessa är dyra, adderar mycket vikt och enbart mater massan 1 537 574 ovan chassiet. Dessa system blir beroende av hur pabyggnaden ser ut och kan resultera i mOnga varianter. Dessa system kan aven vara svara att eftermontera, vilket darmed kan bli dyrt. A problem with the two latter methods mentioned above, which include load cells between the chassis and the superstructure, is that these are expensive, add a lot of weight and only feed the mass 1,537,574 above the chassis. These systems depend on what the structure looks like and can result in many variants. These systems can also be difficult to retrofit, which can be expensive.
Ytterligare ett problem ar att lasten i ett fordon kan forskjutas under kerning, exempelvis vid kuivtagning till foljd av centrifugalkrafter. Harigenom kan lasten komma all skadas. Vidare kan fordonet komma att fâ forsamrade koregenskaper till NO av all fordonets tyngdpunkt forskjuts. 10 Det finns ett behov av all kunna mata aktuell fordonsvikt momentant, utan tidskravande individuell kalibrering av ett matsystem far varje fordon. Another problem is that the load in a vehicle can be displaced during driving, for example during take-off due to centrifugal forces. This can damage the load. Furthermore, the vehicle may have pre-assembled driving characteristics to the NO of all the vehicle's center of gravity shifted. There is a need for everyone to be able to feed the current vehicle weight momentarily, without time-consuming individual calibration of a feeding system for each vehicle.
SAMMANFATTNING 15 Det är darfar en malsattning all utveckla viktmatningen i ett fordon for att lase atminstone nagot av oven angivna problem och armed erhalla en forbattrad viktmatning i fordonet. SUMMARY It is necessary to develop the weight feed in a vehicle in order to read at least some of the above problems and to obtain an improved weight feed in the vehicle.
Enligt en forsta aspekt uppnas denna malsattning av ett lastkannande element i ett fordon. Det lastkannande elementet ar anordnat att bestamma fordonsvikt pa fordonet, vilket inne- fattar atminstone tva hjulaxlar och ett chassi. Det lastkannande elementet är innefattat i en lastbarande fordonskomponent som ingar i en forbindelse mellan respektive hjulaxel och chassi pa fordonet, dar den lastbarande fordonskomponenten har en tillverkningstolerans som understiger ett faststallt forsta gransvarde. According to a first aspect, this grinding is achieved by a load-scanning element in a vehicle. The load sensing element is arranged to determine the vehicle weight of the vehicle, which comprises at least two wheel axles and a chassis. The load-sensing element is included in a load-bearing vehicle component which engages in a connection between the respective wheel axle and chassis of the vehicle, where the load-bearing vehicle component has a manufacturing tolerance which is less than a fixed first inspection value.
Enligt en andra aspekt uppnas denna malsattning av ett farfarande i en berakningsenhet i ett fordon, for bestamning av fordonsvikt pa fordonet. Fordonet har atminstone tva hjulaxlar och ett chassi, samt ett antal lastkannande element. Forfarandet innefattar insamling av ett respektive matvarde fran de lastkannande elementen i fordonet. Vidare innefattar forfarandet summering av de insamlade matvardena. Forfarandet innefattar dessutom berakning av fordonsvikten for fordonet, baserat pa de summerade matvardena, genom omvandling av dessa till ett viktvarde, till vilken en konstant som motsvarar fordonets vikt pa hjul, hjulaxlar och fjadring adderas. According to a second aspect, this objective is achieved by a procedure in a calculation unit in a vehicle, for determining the vehicle weight of the vehicle. The vehicle has at least two wheel axles and a chassis, as well as a number of load-scanning elements. The method comprises collecting a respective food value from the load sensing elements in the vehicle. Furthermore, the method comprises summing the collected food values. The method further comprises calculating the vehicle weight of the vehicle, based on the summed food values, by converting these to a weight value, to which a constant corresponding to the weight of the vehicle on wheels, wheel axles and suspension is added.
Enligt en tredje aspekt uppnas denna malsattning av en berakningsenhet i ett fordon. Be-35 rakningsenheten är anordnad far bestamning av fordonsvikt pa fordonet. Fordonet har atminstone tva hjulaxlar och ett chassi, samt ett antal lastkannande element. Berakningsenheten innefattar en kommunikationsmodul, anordnad all ta emot signaler som represente- 2 537 574 rar ett respektive matvarde fran samtliga lastkannande element i fordonet. Vidare innefattar berakningsenheten en processor, anordnad att summera de insamlade matvardena, samt aven anordnad att berakna fordonsvikten for fordonet, baserat pa de summerade matvardena, genom omvandling av dessa till ett viktvarde, till vilken en konstant som motsvarar 5 fordonets vikt pa hjul, hjulaxlar och fjadring adderas. According to a third aspect, this targeting is achieved by a calculating unit in a vehicle. The monitoring unit is arranged for determining the vehicle weight of the vehicle. The vehicle has at least two wheel axles and a chassis, as well as a number of load-scanning elements. The calculation unit comprises a communication module, arranged to receive all signals representing a respective food value from all load-sensing elements in the vehicle. Furthermore, the calculation unit comprises a processor, arranged to sum up the collected food values, and also arranged to calculate the vehicle weight of the vehicle, based on the summed food values, by converting these to a weight value, to which a constant corresponding to the weight of the vehicle on wheels, wheel axles and suspension added.
Flarigenom; genom att placera lastkannande element i lastbarande fordonskomponenter i ett fordon, dar de lastbarande fordonskomponenterna är tillverkade med en tillverkningstolerans som underskrider ett gransvarde, kan ett matsystem erhallas for att m5ta fordonsvikt 10 pa ett tillfOrlitligt satt utan att tidsOdande och darmed kostsam individuell kalibrering av de lastkannande elementen i varje fordon maste gOras. Flarigenom erhalls en tillforlitligare och fOrbattrad matning av vikten pa fordonet, jamfart med tidigare kand teknik. Flarigenom; by placing load-sensing elements in load-bearing vehicle components in a vehicle, where the load-bearing vehicle components are manufactured with a manufacturing tolerance below a spruce value, a food system can be obtained to measure vehicle weight in a reliable manner without time-consuming and thus costly individual loading. the elements of each vehicle must be gOras. This results in a more reliable and improved feed of the weight of the vehicle, compared with prior art.

Furthermore, the figures are not necessarily to scale, and are, unless otherwise noted, intended to conceptually illustrate aspects of the invention.
Figur 1A visar ett fordon 100 med ett chassi 110. Fordonet 100 kan vara anordnat for att lastas med en last och utgOras av exempelvis en lastbil, langtradare, transportbil, personbil, utryckningsfordon, buss, stridsvagn, motorcykel, brandbil, tag, sparvagn, amfibiefarkost eller annat liknande motordrivet bemannat eller obemannat transportmedel, anpassat far 15 geografisk forflyttning till lands. Figure 1A shows a vehicle 100 with a chassis 110. The vehicle 100 may be arranged to be loaded with a load and consists of, for example, a truck, truck, transport vehicle, passenger car, emergency vehicle, bus, tank, motorcycle, fire truck, roof, tram, amphibious vehicle or other similar motorized or unmanned means of transport, adapted for geographical movement ashore.
I fordonets chassi 110 sitter en lastbarande komponent 120. I den illustrerade utforingsformen utgers den lastbarande komponenten 120 av en fjaderbult, som faster fordonets hjulfjadring 1i chassit 110, i ett framre faste och ett bakre faste. Det finns i denna utforings- form darfor en forsta fjaderbult 120-1 och en andra fjaderbult 120-2 som faster fordonets hjulfjadring i chassit 110 for varje hjulaxel 1i fordonet 100. Andra utfaringsformer kan innehalla ett annat antal fjaderbultar 120. A load-bearing component 120 is located in the vehicle chassis 110. In the illustrated embodiment, the load-bearing component 120 is provided by a spring bolt, which fastens the wheel suspension 1 of the vehicle in the chassis 110, in a front fastening and a rear fastening. There is therefore in this embodiment a first spring bolt 120-1 and a second spring bolt 120-2 which fasten the wheel suspension of the vehicle in the chassis 110 for each wheel axle 1 in the vehicle 100. Other embodiments may include a different number of spring bolts 120.
Figur 1B visar en lastbarande komponent 120 i form av en fjaderbult. Denna fjaderbult 1innefattar ett lastkannande element 150. Figure 1B shows a load-bearing component 120 in the form of a spring bolt. This spring bolt 1 includes a load scanning element 150.
Genom att placera det lastkannande elementet 150, som kan utgoras exempelvis av en sensor, en tradtojningsgivare, en lastcell, ett piezoelektriskt element eller liknande, pa en chassikomponent som bar hela lastvikten, i delta fall tjaderbulten 120 med vilken fordonets hjulladring är infast, erhalls ett vagsystem som är billigt, noggrant och aven innefattar chassivikten. By placing the load sensing element 150, which may be constituted, for example, by a sensor, a wire strain gauge, a load cell, a piezoelectric element or the like, on a chassis component which carried the entire load weight, in some cases the tether bolt 120 with which the vehicle wheel load is attached weighing systems that are cheap, accurate and also include the chassis weight.
En tojningsgivare an ett lastkannande elementet 150 som kan beskrivas som en elektrisk ledare med elektrisk resistans/ motstand. Nar ledaren, traden, utsatts far en fOrlangning 35 eller fOrkortning andras resistansen i den. Genom att mate resistansforandringen kan en uppfattning erhallas om hur mycket och at vilket hall materialet tojs. Forlangning ger okad resistans och vice versa. 4 537 574 En lastcell är en typ av lastkannande elementet 150 som mater krafter. NormaIt sett anvands de for matning av tyngd eller last. En lastcell är normalt konstruerad med hjalp av tradtojningsgivare kopplade i Wheatstones brygga. Effersom differensspanningen typiskt bara är upp till nagot tiotal millivolt kan en forstarkare for att avlasa signalen fran lastcellen anvandas i vissa utforingsformer. A strain gauge on a load sensing element 150 which can be described as an electrical conductor with electrical resistance / resistance. When the leader, the trade, is exposed, an extension or shortening of the resistance of others takes place in it. By feeding the change in resistance, an idea can be obtained of how much and at which hall the material is toasted. Desire gives increased resistance and vice versa. 4,537,574 A load cell is a type of load sensing element 150 that supplies forces. Normally they are used for feeding weight or load. A load cell is normally constructed with the help of wire strain gauges connected in Wheatstone's jetty. Since the differential voltage is typically only up to a few tens of millivolts, an amplifier for reading the signal from the load cell can be used in certain embodiments.
Genom all placera det lastkannande elementet 150 i fjaderbulten 120, som är placerad mellan hjulaxeln 130 och fjadern 140 pa samtliga barande hjulaxlar kan man mata tojning- 10 en som funktion av hela fordonets massa, exklusive axlar och hjul. Vikten pa hjulaxlar och hjul kan dock uppmatas eller uppskattas separat och antas vara konstant. Darned kan en viktberakning kompensera fOr detta genom att addera ett konstant varde. I vissa utfOringsformer kan eventuellt en kompensation gams far smuts, lera och liknande som fastnat pa hjulaxlar och fordonets underrede. Vikten pa denna är lag, eller mycket lag i relation till 15 fordonets totalvikt, kanske i storleksordningen 0-30 kg. By placing the load-sensing element 150 in the spring bolt 120, which is placed between the wheel axle 130 and the spring 140 on all bearing wheel axles, the towing can be fed as a function of the entire mass of the vehicle, excluding axles and wheels. However, the weight of wheel axles and wheels can be measured or estimated separately and assumed to be constant. Darned, a weight calculation can compensate for this by adding a constant value. In some embodiments, compensation may be provided for dirt, mud, and the like that is stuck to the wheel axles and vehicle chassis. The weight of this is law, or very law in relation to the total weight of the vehicle, perhaps in the order of 0-30 kg.
Fjaderbulten 120 är en relativt billig och lattillverkad komponent som gar all tillverka med hOg noggrannhet utan namnvard merkostnad. Vidare ar fjaderbultama 120 tillverkade med hog mattnoggrannhet, da dessa vanligtvis är svarvade. The spring bolt 120 is a relatively cheap and easy-to-manufacture component that can be manufactured with high accuracy without any significant additional cost. Furthermore, the spring bolts 120 are made with high matte accuracy, as these are usually turned.
Ytterligare en fordel genom all placera det lastkannande elementet 150 i en fjaderbult 120 som i sin tur infaster hjulfjadringen 140 i fordonets chassi 110 är att det lastkannande elementet 150 inte är utsatt for statisk belastning fran skruvforbandet. Dessutom paverkas inte givarsignalen fran det lastkannande elementet 150 av ovriga delars styvhet. Darmed kan man undvika att behova g6ra en individuell kalibrering fOr varje fordon 100, vilket underlattar och forbilligar montering. A further advantage of placing the load sensing element 150 in a spring bolt 120 which in turn attaches the wheel suspension 140 to the vehicle chassis 110 is that the load sensing element 150 is not subjected to static load from the screw connection. In addition, the sensor signal from the load sensing element 150 is not affected by the stiffness of other parts. Thus, one can avoid having to do an individual calibration for each vehicle 100, which facilitates and avoids assembly.
Figur 2A visar aterigen ett fordon 100 med ett chassi 110, snarlikt det fordon 100 som tidigare presenterats i figur 1A. Fordonet 100 har en bakre boogiehjulsinstallation, vilken skil- jer sig fran den i figur 1A schematiskt illustrerade framaxeln. Har bar en fjader 140 tva hjulaxlar 1-1, 1-2 som ãr upphangda pa en pivot, aven benamnd boggiebalk. Denna fjader 140 är i det illustrerade exemplet inte upphangt pa ett bultforband utan vilar mot ett fjadersate 120-1, 120-2 monterade i framre boggieaxel 130-1 respektive bakre boggieaxel 130-2. 537 574 Genom aft integrera lastkannande element 150, exempelvis i form av en lastcell i respektive fjadersate 120-1, 120-2 kan ett vagsystem erhallas som är billigt, noggrant och aven innefattar chassivikten p fordonet 100. Figure 2A again shows a vehicle 100 with a chassis 110, similar to the vehicle 100 previously presented in Figure 1A. The vehicle 100 has a rear boogie wheel installation, which differs from the front axle schematically illustrated in Figure 1A. Has a spring 140 two wheel axles 1-1, 1-2 which are suspended on a pivot, also called bogie beam. In the illustrated example, this spring 140 is not suspended on a bolt joint but rests against a spring seat 120-1, 120-2 mounted in the front bogie shaft 130-1 and the rear bogie shaft 130-2, respectively. 537 574 By integrating load scanning elements 150, for example in the form of a load cell in respective spring sets 120-1, 120-2, a weighing system can be obtained which is cheap, accurate and also includes the chassis weight of the vehicle 100.
Det lastkannande elementet 150 kan exempelvis placeras i fjadersateskroppen 120-1, 12 och ett lock kan placeras pa det lastkannande elementet 150, som en utbytbar detalj da denna slits nar fjadern 140 glider aver det lastkannande elementet 150 pa fjadersatet 11, 120-2. 10 En fardel harmed är aft det lastkannande elementet 150 skyddas fran forslitning och utbytesintervall av dessa forlangs. Placeringen av det lastkannande elementet 150 gar att hela fordonets massa kommer att baras av det lastkannande elementet 150, oavsett ojamnheter som boggin kompenserar for. Om det lastkannande elementet 150 konstrueras sa aft en-bad kraftvektorn i vertikalled upprnats, sa kan man eliminera eventuellt bidrag fran sidolas- 15 ter och friktionslaster. The load sensing element 150 can for instance be placed in the spring seat body 120-1, 12 and a lid can be placed on the load sensing element 150, as a replaceable detail as it wears when the spring 140 slides over the load sensing element 150 on the spring set 11, 120-2. A part of the carriage is thus protected by the load-sensing element 150 from wear and replacement intervals thereof. The location of the load sensing element 150 means that the entire mass of the vehicle will be supported by the load sensing element 150, regardless of irregularities that the bogie compensates for. If the load sensing element 150 is constructed so that both the vertical force vector is obtained, then any contribution from lateral loads and friction loads can be eliminated.
Den har diskuterade placeringen är aven fordelaktig ur ett service- och installationsperspektiv. De lastkannande elementen 150 är integrerade i sm5 komponenter som 5r latta aft byta och sitter skyddade; detta galler alien den utforingsform som askadliggjorts i figur 1A 20 och 1B. Vidare mojliggors installation av ett vagsystem utan all behova kalibrera varje individuellt lastkannande element 150. The location discussed has also been advantageous from a service and installation perspective. The load scanning elements 150 are integrated in small components which are easy to change and are protected; this applies to the alien embodiment embodied in Figures 1A and 1B. Furthermore, the installation of a weighing system without any need to calibrate each individual load scanning element 150 is possible.
Figur visar en fjader 140 i en boogiehjulsinstallation, exempelvis i fordonet 100 som askadliggjorts i figur 2A. Fjadern 140 vilar i sin ena ande pa ett fjadersate 120 i en av for- 25 donets hjulaxlar 130. I detta fjadersate 120 kan i vissa utfOringsformer ett lastkannande element 150 vara monterat. Detta lastkannande element 150 kan ha ett skyddslock 160 monterat, anordnat att placeras mellan det lastkannande elementet 150 och hjulfjadringen 140 sa aft det lastkannande elementet 150 skyddas fran forslitning till foljd av hjulfjadringens rorelse vid belastning. Det lastkannande elementet 150 kan utgaras av en lastcell, en- sovissa utforingsformer. Vidare kan det lastkannande elementet 150 vara konstruerat att enbart karma av krafter i vertikalled enligt vissa utfaringsformer.

It should be noted, however, that some of the described steps 301-304 may be performed in a different chronological order from what the numbering order suggests and that some or a plurality of them may be performed in parallel with each other, according to different forms of performance. Furthermore, certain steps are performed only in certain embodiments, such as, for example, step 302. The method 300 includes the following steps: Step 301 A respective food value from the load scanning elements 150 in the vehicle 100 is collected.
Matvarden kan tas emot fran de lastkannande elementen 150 Over ett tradbundet eller tradlast granssnitt enligt olika utforingsformer. The food guard can be received from the load-scanning elements 150 over a wired or wire-loaded interface according to different embodiments.

Sadan lasfforskjutningsvarning kan innefatta exempelvis att en varningslampa tands i fordonets instru- mentpanel, en auditiv varningssignal utlOses, eller liknande. Collected 301 food items from load-sensing elements 150 placed on different wheel axles 1 on the vehicle 100, and / or placed on the right and left sides of the vehicle 100, respectively. If the difference between these food values exceeds a second spruce value, a load displacement warning can be triggered to grab the driver's attention. Such a laser displacement warning may include, for example, a warning light being lit in the vehicle's instrument panel, an auditory warning signal being triggered, or the like.
Flarigenom kan en forskjutning av lasten i fordonet 100 under fard detekteras och aven atgardas av foraren innan flagon olycka intraffar. In this way, a displacement of the load in the vehicle 100 while driving can be detected and also guarded by the driver before a flag accident occurs.
Steg 303 De insamlade 301 matvardena som samlats in fran de lastkannande elementen 150 i fordonet 100, summeras. Step 303 The food values collected 301 collected from the load scanning elements 150 in the vehicle 100 are summed.
Steg 304 Fordonsvikten for fordonet 100 beraknas, baserat pa de summerade 303 matvardena, genom omvandling av dessa matvarden till ett viktvarde, till vilken en konstant som motsvarar fordonets vikt pa hjul, hjulaxlar 130 och qadring 140 adderas. 8 537 574 Exempelvis kan matvarden lagras exempelvis i en tabell, eller en graf dar matvarden, motsvarande tojningsvarden är mappade mot viktvarden p fordonet 100 och dess last. 5 Flarigenom kan en kontinuerligt uppdaterad viktberakning av fordonet 100 erhallas, vilket mojliggor aft en mer exakt berakning av fordonsvikten kan anvandas som parametervarde i de berakningar som utfors i fordonet 100, som exempelvis berakning av bransleforbrukfling, mojlig rackvidd med nuvarande branslemangd, bromsstracka etc. Step 304 The vehicle weight of the vehicle 100 is calculated, based on the summed 303 food values, by converting these food values to a weight value, to which a constant corresponding to the weight of the vehicle on wheels, wheel axles 130 and suspension 140 is added. 8 537 574 For example, the food value can be stored, for example, in a table, or a graph where the food value, corresponding to the strain value, is mapped to the weight value of the vehicle 100 and its load. In this way, a continuously updated weight calculation of the vehicle 100 can be obtained, which enables a more accurate calculation of the vehicle weight to be used as parameter values in the calculations performed in the vehicle 100, such as calculation of fuel consumption, possible rack width with current fuel quantity, braking distance, etc.
