Description

TECHNICAL EMBODIMENT The present invention relates to a method for leveling water shoes in a mobile unit according to the preamble of claim 1. The present invention also relates to a system. arranged for, level feeding of water shoes in a mobile unit according to the preamble of claim 20, as well as a computer program and a computer program product, which implement the procedure according to the invention.

Background The following background description provides a description of the background to the present invention, and thus does not necessarily constitute prior art.

Mobile devices, such as vehicles or craft, such as ships, aircraft or other mobile devices, often include one or more containers for water shoes. These water shoes may include washers which are required for the operation of the mobile unit, for example branish, cooler water, washer water, various types of lubricating water, such as motor or waxing soles, hydraulic water shoes, or exhaust gas cleaning agents, for example containing urea or other reducing agent. The water shoes can also include other types of water shoes that do not significantly affect the performance of the vehicle. For example, the containers may contain drinking water or other beverages. The containers can also be transport containers, in which water shoes are transported in the mobile unit. It should be understood that water shoes transported by the mobile device may be largely ay. which type of heist, for example chemical water shoes, oil heater heating, or food water shoes, since a transport container can be filled with essentially any liquid heist. In this document, the invention will be discussed in detail for its application in molds. However, the person skilled in the art realizes that the invention can also be implemented in substantially all types of mobile units in which water shoes are included in containers, for example the above-mentioned vehicles, ships and the film lamp.

Containers for waders often include one. feeding device, which Or arranged to feed the water level fbm the liquid in the container, since it is afro important to know how much liquid is in the container. For example, for the fluids that are important for the operation of the mobile unit, it is important to veto any fuel, smrvvatska, spolarvatska ochiel] er coolervatska that are left in the respective containers in the mobile unit.

Therefore, the containers in the mobile unit are often provided with a feeding device comprising one or more of a float, an ultrasonic sensor or any other device which can record an act of reporting a water level in the container. The. The matte water level Sari is then used to determine the available volume of water in each container.

For mobile devices comprising an engine, for example, Oct is hot enough to be able to rely on the availability of engine and gear oil to adequately lubricate the engine. respectively vaxelladan. In addition, there is an obligation on certain government requirements to be able to properly feed five uses of reducing agents, such as urea or AdBlue, in order to be able to prove that sufficient exhaust gas purification has been performed.

For water shoes that are transported in a transport container in the mobile echo tone, it is important to be able to monitor the water level in the container to be sure that the container is closed. This applies especially to the transport of neck straps. water shoes, as well as various types of chemicals. BRIEF DESCRIPTION OF THE INVENTION For mobile units comprising one or more hopper holders with feeding devices, Oct rid an individual mating case is black to correctly interpret which actual water level a measurement signal generated by a feeding device for feeding water hoist in a hopper actually corresponds to. This is due to the fact that the food value -F7Yr the water level in the food case ooh / or yid the food point is sometimes higher / lower than it should be because the liquid in the container splashes around in the container and / or has a non-horizontal seat. This rippling and / or this non-horizontal surface Ian, for example, is caused by the mobile unit accelerating or decelerating, or by, for example, a vehicle comprising the container being located in an uphill slope.

Previously, this problem was listed by the food values from the food device being averaged over time. The idea is then that the occasional erroneous values have a small, and for food insignificant, effect on the mean value-formed value for the water level if the mean value formation is made over a relatively long time. In other words, these previously known solutions have always calculated an average value for the water level over a relatively extended period of time so that occasional incorrect values for the water level will not cause errors in the mobile unit, such as alarm signals, incorrect system controls and the like.

However, it is not always advantageous to co-form these level food values over time periods. The average value formation quadruples the incorrect value Over the period of time for which the average value formation takes place. Dents also have their own vericfa (ieke-feaktiga.) Values quadrupled over this time period in a corresponding way, which means that the mean value formation of the niva food values risks "lowering" real deviating values by weighting them together. ails 3 audra varden during the time period. As a result, the formation of the mean value gives a time delay, which causes a rapid real change of the level food values Roomer 'to give a delayed changed mean level value.

For example, in the event of a rapidly declining level of engine, gearbox or brake oil, this is an important type of dust and warning system in the mobile unit as soon as possible to determine whether the level is indeed rapidly declining in order to implement measures that protect the mobile unit and / or a celebrant and any passengers.

It is therefore an object of the present invention to provide a method and a system for level feeding of water shoes in a mobile unit which correctly identifies incorrect food values and correct food values, respectively.

This object is achieved by the above-mentioned method according to the rabbit-drawn part of claim I. The object is achieved by the above-mentioned system according to the pitcher-part of claim 20 and by the above-mentioned computer program and computer program product.

Through the method and system according to the present invention, a plausibility analysis of the food signal / food value there is obtained influenced by environmental factors, which can be used to increase the accuracy of the food values for the water levels.

By utilizing the method and system according to the present invention, the reliability of the supply of the water level is determined based on whether the mobile unit is affected by environmental factors. Thereafter, the food is utilized with the consideration taken to the determined reliability. 4 AlitsA, the feed can be interpreted on the basis of Iran the reliability that results from the possible external influence, which means that gains in precision and / or time. can Oras for the feeds of Liquid levels in the mobile device. This increased speed and / or precision may prevent damage to the mobile device and / or a driver and / or passenger in the mobile device.

Thanks to the present invention, unreliable food values can be treated differently, for example by being ignored or by taking less account of these unreliable food values, which reduces the risk. for erroneous decisions to be made based on unreliable values. Thus, utilization of faic level detections can be avoided by the present invention.

The present invention thus results in an overall 1-16g-higher quality of decisions read by control units / control systems in the mobile unit. In addition, even rapid changes in the water level can be followed when the present invention is used, which reduces the risk of, for example, engine failure due to rapid engine oil leakage, or of gear failure due to. rapidly leaking gear oil, as the rapidly declining oil level. SAFE will be discovered, whereby. Appropriate Actions, such as protective disturbances and / or seals, can be carried out to ensure that the engine / gearbox is protected.

According to an embodiment of the present invention, the determination of what effect the at least one environmental factor had on the food values of the water level in the first container is based on a second feed of at least one second liquid level in at least one second container for the liquid device arranged in the mobile unit. About the food values for the first container and. for At least a second container moves substantially uniformly no conclusionPn drawn an environmental factor reasonably affects the metrics, since the environmental factors affect all containers in the mobile unit. Alitsd can eat. in this. fail fixedstdilas corn joke reliable because they are influenced by At least one environmental factor. This embodiment can be implemented with very little addition in complexity, since several liquid containers in today's mobile units, as exemplified in fordpn, are already often provided. with measuring devices.

The present invention can therefore increase the precision of meetings and / or decisions in the mobile unit with very small differences in manufacturing cost and / or complexity.

Figure 3 shows a schematic container with MDF units, Figure 4 shows a control unit according to the present invention. Description of Preferred Embodiments 1-2 Figure 1 schematically shows an exemplary vehicle 100 embodying the present invention. The vehicle 100, which may be a passenger car, a truck, a bus, or another vehicle, includes a powertrain which conveys power to the drive wheels 113, 114 of the vehicle 100. The powertrain comprises an internal combustion engine 101, which in a conventional manner, via a 6 on the shaft 102 of the combustion chamber 101, the furnace is with a gearbox 103 via a coupling 106. The combustion engine 101 is driven by fuel from one. fuel tank 130, to which the internal combustion engine 101 is supplied via an industry line 131, as well as a hose or the like. The engine 101 is lubricated by engine oil, which is lubricated in an oil trajectory and the engine 101 is distributed by the internal parts of the feeder when they rotate the engine 101. Gearbox, Th 103 smOrls of a waxing ladle, which is located directly in the space in the gearbox. as axles ash gears firms in, ash viiken is distributed within the gear cell 103 when its gears ash axes rotate.

An output shaft 107 of the Iran gearbox 103 drives the drive wheel 113, 114 via an end shaft 108, such as e.g. a conventional differential, ash drive shafts 104, 105 connected to the said final shaft 108.

The vehicle 100 includes an exhaust gas treatment system 120 for treating / purifying exhaust gases resulting from combustion in the combustion chamber of the combustion engine 101. The exhaust gas treatment system 120 may comprise a container of reducing agent 121, in the silk, for example, urea slier AdBlue is stored in the exhaust gas treatment system 120 during its exhaust purification.

The internal combustion engine 101 is controlled by the control system of the vehicle via a control unit 150. Likewise, the clutch 106 (ash gearbox 103 can be controlled by the control system of the vehicle with the aid of one or more additional control unit displays). Of course, the vehicle's driveline may also be of a different type, such as a type with conventional automatic transmission, of a type with. hybriddilv] ina, etc.

The control unit. 150 according to the present invention also comprises a first fixing unit 151 and a second fixing unit 152, and is connected to, and receives measuring means from, at least one feeding device for measuring a water level in a container in the tardon. The first. the determining unit 151 and the ahdra. the fixing unit 152 is described in detail below. In the example of Figure 1, the control unit 150 is connected to a feed device for leveling the engine oil in the engine 101, to a measuring device for leveling the gearbox oil in the gear unit 103, to a measuring device for feeding the bulbs in the brahsi tank 1 and to a feeding device for leveling the reducing agent. the tank for reducing agent 121. The control unit 150 is also connected to a medium supply for level supply of at least one additional liquid. AtmAnstone an additional container 140, which may for example be one or more flora of flushing liquid, cooling liquid and liquid in a transport tank of the vehicle. One skilled in the art will also recognize that substantially any type of liquid container containing substantially all of the type of liquid fed by a feeder may be connected to the control unit provided. All measurement signals are supplied to the control unit 150.

Figure 2 shows a flow chart of the process of the present invention. In the first stage 201 of the procedure, a first meeting is performed by Atminstnne a first liquid shaker a first container for water shoes, where this first container Or is arranged in the mobile unit. For example, the level of engine oil in the engine 101 in the vehicle 100 can be met by a dosing feeder. a second strut 202 of the process is determined to have an effect. At least one environmental factor may have on the first feed pitch in the first stage 201. It. at least one environmental factor. hdr consists of an environmental factor that affects the mobile device. For example, the environmental factor may be a road section for a road section on which a vehicle 100 is located.

In a third step 203 of the method of the present invention, the first measurement in the first step 201 is determined to be reliable. This determination of the reliability of the first feed is based on the determination of the effect parsed in the second stage 202 of the method.

By the method of the present invention,. The reliability of the first saturation of the water level is determined based on whether the mobile unit there is affected by environmental factors, after which the feed can then be used with regard to all the determined. reliability. In other words, it is established that the mobile unit is influenced from the outside, after which the food signal / measure from the food device is interpreted on the basis of the reliability that results from the actual impact from the outside. Thus, when the present invention is applied, gains in precision and time can be made for the feeds of water levels in the mobile unit.

As a result, non-reliable food values can be treated differently, for example by being ignored or by taking less account of these non-reliable food values. This significantly reduces the risk of decisions being made based on lake-reliable food values. This is an overall higher quality of decisions. In addition, even rapid changes can occur when the present invention is utilized, which reduces the risk of, for example, engine failure. due to rapid engine oil leakage.

Previously known attempts at solutions to problems with. Water level feeds have resulted in considerable work and 9 considerable manufacturing costs being placed on various optimizations of tank geometries and / or placements of food points in containers to minimize the impact of environmental factors. By utilizing the present invention, this problem can instead be handled in the software by control units / control systems, which is a considerably less labor-intensive and less costly solution to the problem.

According to an embodiment of the present invention, the determination of at least one environmental factor affecting the food value is based on a slope experienced by the mobile unit when the feed is made. This slope a can be. either in the direction of travel of the mobile unit and / or at an angle to the direction of travel.

Since the mobile unit is a vehicle, the slope may be the road surface on a road section on which the vehicle is located. The vehicle inclination a can then indicate the inclination along the direction of travel of the vehicle and / or the inclination of the vehicle a at an angle to, for example, perpendicular to, the direction of travel of the vehicle. The direction of the vagal inclination a may have an effect on the vagiutation's effect on the cloud level feed after the liquid container in which the feed is made may have a geometric design and / or may have a position of the feeding device, which makes the feed more probable for inclinations in one direction. If, for example, the feed point, such as the float door or ultrasonic device Or is located, in one direction of the container in the direction of travel, but centrally in a direction perpendicular to the direction of travel, then it means that vagiutning in the direction of travel has a greater effect on the feeds than the direction of travel. This is described in more detail below. The carriage a can be horse-fed / fed by the vehicle itself, for example by using an accelerometer, a force equation. and / or a hbjdfbrandxing. In systems where information is exchanged with: Lan vehicles are also used Pan. '-; vaglutnina a and / or your information related to a vagiutting a estimated by a vehicle is provided to other vehicles, either directly, or via an intermediate unit such as a database or the like. Thus, the road inclination can be determined based on information provided by another vehicle.

The slope of Pan is also determined based on topographic map data, for example map data from digital maps containing topographic information. Vii determination is often used to take positioning information, such as GPS information. (Global Positioning System). With the aid of the positioning information, the position of the vehicle in relation to the map data can be determined so that the vaginal slope a can be extracted from the map data. The positioning information can also be based on radar information, on camera information, on information from another vehicle, on positioning information previously stored in the vehicle.

The day. Topographical Parties, and Even today's positioning systems, have high accuracy, which means that excavation factors which depend on the vagiutning a can be determined quickly and accurately in the vehicle.

The route guidance at Pan Oven is determined on the basis of in-vehicle position previously stored positioning information and route guidance information, or on information. ernallen Iran traffic system related to said vague section. 1 flema. In the existing cruise control system, map data and positioning information are utilized in the cruise control. Such systems can provide map data and positioning information to the present invention system, thereby minimizing the complexity of determining the direction of the sag.

The slope that the mob ha unit experiences can also constitute a terrain slope if the vehicle is located in the terrain, that is to say outside the vehicle, for example if the vehicle is a tractor or another off-road vehicle.

The slope as the mobile device. experience can also utqdra one. water leakage a caused by said mobile unit in conjunction with one or more formations of water, for example vapor, am the niobile unit Is a water vessel, such as a vessel, the silk hefinner sic in / on water.

Correspondingly, the slope that the mobile unit experiences can also constitute an air slope a, which is caused by the mobile device interaction with. Daft. The mobile unit for this embodiment is typically a flying vehicle, such as a flywheel or a helicopter, the silk is in the air.

According to one standard, it is at least an enveloping factor which. Affects the vehicle depending on how the vehicle is driven. Therefore, the determination can be made as to what effect the at least one emission factor may have on the measurement if the water level is accelerated on the driving of the vehicle.

If the vehicle is accelerated, this causes an environmental factor that affects the feed, as water shoes in the container in the vehicle move at great speed. Vehicle acceleration. may have alitsa cooperate with the design of the container as well as any feremal, for example extraction means, in the container.

Typically, wave formations occur in the vehicle's direction 12 of the tanks as the vehicle accelerates, which (= so that the water level determined by the center device may correspond poorly with the actual water level in the heliallar).

A slow and / or even acceleration often causes less vague formations in the behdliar into fast and / or jerky / uneven accelerations. It may, however, be the case that a slow and / or steady acceleration can be judged to give reliable measurements, while fast and / or jerky / uneven accelerations give jockey reliable measurements. in the same way, decelerations in the vehicle affect the supply of white rail levels in the vehicle's fluid reservoir, since vagal images are also then created in the bone vessels. Sometimes a slow and / or slow deceleration can give reliable mean values while fast and / or vigorous / slow decelerations give unsatisfactory values.

Thus, according to the embodiment, the reliability of the first feed can be determined based on whether the vehicle accelerates / decelerates. Acceleration / deceleration can be determined based on a vehicle speed signal, for example by deriving the speed signal, based on information. from an accelerometer, based on positioning information, based on information about the requested engine torque, or based on other useful information from which acceleration / deceleration can. determined.

Other types of vehicle propulsion can also have an effect on the measurements of white level in the vehicle's alloy wheels. For example, a driving vehicle may have a speed exceeding a threshold value vt: r „, hold at the same time as the vehicle has a steering wheel stroke c Exceeding a threshold value for steering wheel stroke ctn„ .. affect the feed. Therefore, according to the embodiment, the reliability of the feed can be determined based on the speed of the steering wheel a.

According to an embodiment of the invention, at least one control unit 150 in the mobile unit, for example in a vehicle 100, comprises information to what extent / extent the various respective environmental factors affect the supply of water levels in the containers in the unit. This information may include a location of at least one feeding point in each container and / or a geometry for each container and / or a functional roreise Thom respective container.

As mentioned above, the geometry of the container and / or the position of the food point j the container can affect Our star impact accelerations, decelerations, speeds exceeding the spruce value speed vtnreshold at the same time as steering range Exceeding giansvard Cttjrejoi, vagiutningar and other environmental factors at the water levels fOr. This is schematically exemplified in Figure 3, where a liquid container 300 is subjected to an ambient factor in the form of a variation in the direction of travel, which causes the surface 301 of the liquid to be inclined relative to the container because the container has an angle of inclination corresponding to the horizontal surface to the horizontal surface. The location of the food point may have a significant effect on the food result. As illustrated in the figure, the ambient factor affects the vagueness of the food value corresponding to food points 302, 303 in the spirits of the container in the direction of travel, while the food value is less affected at a food point in the middle of the container. The location of the food points across the direction of travel affects in a corresponding way the food values at the slope of the food direction in the opposite direction of travel. 14 The geometry of the container can also correspondingly affect the influence of the environmental factors on the food values, since the design of the volume within the container can counteract or contribute to. impact of environmental factors -.0a. vatskeytah, con adrmed pa vatskenivan, i behallaren. In addition, the geometry of the container in conjunction with the location of the food point can affect the effect of environmental factors on food values.

The functional rudder travel of the respective tank as the at least one control unit 150 has information on the San consists, for example, of information on how rotating parts inside the engine 101, or rotating gears and axes with the gearbox 103 affect the feeding of water levels in the tanks in the unit, for example when feeding ay. engine- oh / or gear oil.

In the development of previously known solutions to the present problems, considerable fashion and also considerable manufacturing costs have been spent on optimizing geometries and / or placements of food points in containers in order to minimize the impact of the environmental factors. By utilizing the present invention If this problem is instead handled by control units / control systems in the mobile unit, there is a considerably less costly solution.

According to one embodiment of the present invention, the determination of the effect is based on it. At least one environmental factor was on the food values for the water level. a second supply of at least one second water level in at least one second container for water shoes arranged in the mobile unit.

However, the determination of the effect of the environmental factors on the food values may include an analysis of the values of the first feeds of the first water level in the first container and the values of the second feeds of the at least one second water level in the at least one second container or otherwise changed. . For example, having the first food value obtained in a first container, such as a fuel tank, may be compared with other foodstuffs son coda] ice in at least one second container such as a flushing water container. If the first food values for the first container and the second food values for it At least one second container changes in a similar way in some way, for example about the food values. fOr bAda the containers. Affected by a vagal slope as illustrated in Figure 3, sA can. the analysis results in the food values changing substantially uniformly.

If a uniform change for several liquid containers can be established, it can be concluded that environmental factors affect the food values, since the environmental factors should affect all containers in the mobile unit. In this way it can be established that the first feed of the liquid level in the first container, and the other feedings in the at least one second container, are not reliable, since they were affected by Atmin at least one environmental factor.

If, instead, it can be established that a uniform change does not exist for several water containers, it can be concluded that environmental factors do not affect the values, since the environmental factors should have affected all containers in the mobile unit. In other words, the answers should be reliable.

According to one embodiment, if the uniform change in time involves substantially synchronous reactions, it will be said that changes in the food values in the different containers occur essentially at the same time. According to one embodiment, the substantially uniform change comprises historically similar changes, i.e. that changes in the values occur which are substantially equal in the different containers, since these changes must not be synchronized in time. The 16th vase. likformiqa. The change Ian also contained. combinations of temporally substantially synchronous reactions and star-like mass-like burnt rings.

According to an embodiment of the invention, the first saturation of the first knowledge knife is judged to be unreliable if the at least one environmental factor should have had a significant effect on said first feeding. By substantial influence can be meant, for example, that the at least one environmental factor of a food value deviates by 5-20%, and according to an embodiment by at least 10%, from a real value for the wheat knife.

When the control unit / control system is fixed here during the first feeding of the water level, it is reliable or not horsepower according to one embodiment a value for the water level. The value for the water knife is determined here based on the fixed reliability for the first feed.

Vardet fbr vatskenivan ken. for example, is determined by an averaging, which according to an embodiment of the invention is adapted based on the effect that At least one environmental factor is considered to have on the first saturation.

This adaptation of the mean value formation Ian include an adaptation of a number of food values that are included in the mean value formation. Here the lesser food value is taken with the first feeds bed: 5ms as reliable, whereby the value for the water level Ian is determined faster because the feeds are reliable. Through this adaptation ken alitse fast father: and-rings fbllas am reliable food is available. Correspondingly, the food value is included in the mean value formation, and the first feed is called a joke. 1 7 The mean value slope can also be adapted by utilizing weighting factors in the mean value blood Sc to the food value which. bed6ms som til] forli * ijga ges hagre VI It an matvarden villa bedoms som atilifdriltliga.

Alitsa Ian the speed and / or precision of averaging, and thus. for the determination of the value of the water level, is adjusted based on the established reliability of the food values, which is advantageous.

According to a. another embodiment ignores the feed am den. the first supply of the first water level is judged to be reliable. This avoids incorrect decisions Read on unreliable food values for water levels.

According to an embodiment of the invention, one or more of a control unit and a control system arranged to refrain from performing an operation in the supply of water level are judged to be unreliable. Has therefore refused the control unit / control system to carry out an action that should have been carried out during the feeding had been judged to be reliable. Alitsa is connected, the control unit / control system's action to the fixed availability of the feeds, which means that the occurrence of incorrect actions, which are based on incorrect data, is reduced.
