    1015202530In this context, vehicles refer to, for example, trucks, lorries, flatbed trucks,transport car, truck, motorhome, pickup, work trailer, car, emergency vehicle,vehicle, van, quad bike, forwarder, excavator, car, car, crane truck, tanker,motorcycle, wheel loader, moped, scooter, limousine, sports car, race car, radio car,lawn mower, tank, snowmobile, snowmobile, off-road vehicle, tracked vehicle, tractor,go-kart, bus, combine harvester, agricultural machine, or other similar motor-drivenmanned or unmanned means of transport, adapted for land-based geographicaldisplacement.
    However, this is a particularly big problem for heavy traffic such as trucks, trucks,bus, timber truck, etc., as these are often equipped with speed limitsthrottling that makes speeds over a certain speed, for example 90 km / h, impossible, partlyloses more traction than lighter vehicles on uphill slopes. This leads to twotrucks on a straight line on a flat motorway section with good visibility and road conditions inrule drives at 90 km / h, ie the maximum possible speed for heavy traffic (ondue to legal requirements in many countries, including Sweden). Uphillhowever, these vehicles may have different capacities or tensile strengths, for example ondue to differences in engine power or vehicle load. A heavy vehicle behindwith better traction uphill may then want to try to drive againvehicle in front, the problem for the driver is to know if this is possible beforethe uphill slope ends, as both vehicles will probably have the samespeed downhill or on a flat road, ie where the driver still does notcome by. The driver of the vehicle behind usually does not know thatin front of the vehicle's performance and load conditions.
    Another problem with overtaking is that the overtaking driver normally does notknow what the road in front looks like after overtaking; for examplethere may be a hidden curve in front or exit that makes overtaking dangerousor inappropriate.
    Another problem for the driver of the vehicle behind is that he does notknow for sure what the traffic situation looks like in front of the vehicle in front.
    It can, for example, be a long vehicle queue as a result of a traffic accident orsimilar in front of the vehicle in front. A overtaking of this vehicle10152025then leads to increased fuel consumption without reaching the final destination faster, whichmakes overtaking essentially meaningless.
    It can be stated that much still remains to be done to make it easier for onedriver in an overtaking situation.
    SUMMARYIt is therefore an object of this invention to facilitate prior planningovertaking a vehicle in front, to solve at least some of the abovespecified problems and thus achieve a vehicle improvement.
    According to a first aspect of the invention, this object is achieved by oneprocedure in a calculation unit in a vehicle to facilitate planning aheadovertaking a vehicle in front. The method involves data collectionassociated with a change in speed of the vehicle in front as a wholefirst road section in the direction of travel of the own vehicle, from a sensor. The procedurealso includes calculation of the speed change of the foregoingthe vehicle under the first road section. Furthermore, the method comprises collectingspeed-related information associated with your own vehicle. The procedurealso includes the collection of route-related data, associated with apresently other road sections in the direction of travel of the own vehicle. The procedurealso includes calculation of the drivability of the vehicle in front ofthe present second section of road, based on the calculated speedthe change of the vehicle in front, the collected speedrelated information associated with the own vehicle and collectedroute-related data, associated with the preceding second section of the road.
    The method also includes presentation of the calculation made therefromthe drivability of the vehicle in front of the driver, in order to therebyfacilitate his planning before overtaking the vehicle in front.1015202530According to a second aspect of the invention, this object is achieved by onecalculation unit in a vehicle to facilitate planning before overtaking avehicles in front. The calculation unit comprises a receiver arranged tocollect data associated with a speed change of the foregoingthe vehicle, during a first road section in the direction of travel of the own vehicle, from asensor. The calculation unit also comprises a processor circuit, arranged tocalculate the speed change of the vehicle in front. Processor-the circuit is also arranged to collect speed related information associatedwith their own vehicle and also arranged to collect route-relateddata, associated with a pre-existing second road section of the own vehicledirection of travel. In addition, the processor circuit is arranged to calculate thethe reversibility of the vehicle on the second road section in front,based on the calculated velocity change of the foregoingthe vehicle, the collected speed-related information associated with itown vehicle and collected route-related data associated with itin front of the second road section. Furthermore, the calculation unit comprises acommunication connection, arranged to communicate data representing itmade the calculation of the drivability of the vehicle in front to aindicator.
    By measuring the actual values of speed change for a person in frontvehicles during a first road section, this information can be used to calculateonein front of other road sections. This way of assessing overtaking is moreand forecast whether a overtaking of the vehicle is possible duringreliable than assessments based solely on map data and / or instantaneous relativespeed between vehicles. This gives a more reliable assessment of whetherthe vehicle in front is drivable under a certain section of road, whichprovides a safer driving of the vehicle, but also saves fuel and thusalso money by making unnecessary and / or hopeless overtaking attempts possibleavoided. By avoiding unsuccessful overtaking attempts, the environmentalthe load. In addition, the road's passability for other road users, then itthe overtaking lane is blocked by a vehicle that does not pass oneanother vehicle.10152025Other benefits and additional features will become apparent from the following detailsdescription of the invention.

    DETAILED DESCRIPTION OF THE INVENTIONThe invention is defined as a method and a calculation unit forfacilitate the planning of overtaking of a vehicle in front, which canrealized in any of the embodiments described below. This inventioncan, however, be implemented in many different forms and should not be seen as limited by thosethe embodiments described herein, which are instead intended to illustrate andillustrate various aspects of the invention.
    Additional aspects and features of the invention may become apparent from itthe following detailed description when considered in connection with the attachedthe figures. However, the figures are only to be considered as examples of differentembodiments of the invention and should not be construed as limitingthe invention, which is limited only by the appended claims. Furthermore, the figuresnot necessarily to scale and are, unless otherwise specifically stated, intendedto conceptually illustrate aspects of the invention.
    Figure 1A shows a vehicle 100 traveling in a direction of travel 105 on a horizontalbase 110 towards a final destination. The vehicle 100 has a sensor 130, locatedfor example inside the wheelhouse behind the windscreen so that objects and / or vehiclesin front of the own vehicle 100 can be detected. You can also imagine otherslocations, for example, the sensor 130 may be located on the outside of the wheelhouse orroofs according to certain embodiments, or for example on the vehicle's bumper orchassis. However, it is an advantage to have the sensor 130 located inside the wheelhouse when itwhere is relatively protected from dirt, dust and sleet, which has abeneficial effect on sensor function, reliability and service life. to some extentthe sensor 130 is also slightly more protected from damage as a result of a traffic accident, theft,damage, and / or other damage by unauthorized persons when placed inside the wheelhouse.10152025The sensor 130 may comprise, or consist of, for example, a radar meter, aLaser meters such as a Light Detection And Ranging (LIDAR), sometimesalso called LADAR or laser radar, a camera such as a Timeof-Flight camera (ToF camera), a rangefinder based on ultrasonic waves orsimilar device configured for distance assessment.
    A LIDAR is an optical measuring instrument that measures the properties of reflected lightto find the distance (and / or other properties) of a remoteobject. The technology is very similar to radar, (Radio Detection and Ranging), butinstead of radio waves, light is used. Typically, you measure the distance to an objectby measuring the time delay between a transmitted laser pulse and the registered onethe reflex.
    A Time-of-Flight camera (ToF camera) is a camera system that takes a sequenceof images and measures a distance to an object based on the knownthe speed of light, by measuring the time required for a light signal between the cameraand the motif / object. A Time-of-Flight camera can be said to be a kind of non-scanning LIDAR, where the entire scene is captured with each laser or light pulse, in contrastto point by point with a laser beam as when scanning with LIDAR systems.
    The sensor 130 may also include, or consist of a communication module,arranged for wireless communication with a surrounding, in particular onein front, vehicles and through this wireless communication obtainrelated to itspeed change per unit time, type of vehicle, engine speed,information communicated to the vehicle,speed,gear selection, load quantity, total weight and similar information.such as, for exampleFurthermore, the vehicle 100 may comprise, or consist of, a plurality of sensors 130 ofeither the same type of sensor 130 or different types of sensors 130 according to differentembodiments. An advantage of having a plurality of sensors 130 is that you can thenmake more reliable assessments of distance / speed and / or identification ofvehicle in front or vehicle type.10152025It may further be an advantage to use sensors 130 that already existmounted in the vehicle 100 for other purposes, such as warning the driver tothe distance to the vehicle in front is too small, etc .; collision detector, or othersimilar sensor 130. This can avoid fitting a special sensor130 for this particular invention, leading to lower manufacturing costs and abetter resource utilization.
    Figure 1B illustrates an example of the driver environment in the vehicle 100.
    In support of overtaking, the vehicle 100 is provided with a calculation unit 120,located in, or adjacent to, the vehicle's wheelhouse. This calculation unit 120 isarranged to communicate with the sensor 130 over a wired or wirelessinterfaces according to different embodiments.
    The wired interface may, for example, be based on any of the followingtechnologies: Controller Area Network (CAN), Media Oriented Systems Transport(MOST), Ethernet, (USB), RS232, FireWire,Thunderbolt, to name just a few possibilities.
    Universal Serial Bus SerialFor example, the wireless interface may be based on one of the followingtechnologies: Global System for Mobile Communications (GSM), Enhanced DataRates for GSM Evolution (EDGE), Universal Mobile Telecommunications System(UMTS), Code Division Access (CDMA), (CDMA 2000), Time DivisionSynchronous CDMA (TD-SCDMA), Long Term Evolution (LTE); Wireless Fidelity(Wi-Fi), defined by the Institute of Electrical and Electronics Engineers (IEEE)standards 802.11 a, ac, b, g and / or n, Internet Protocol (IP), Bluetooth and / orNear Field Communication, (NFC), according to different embodiments.
    A second vehicle 140 in front drives in front of its own vehicle 100. In the vehicle100, there is further provided an indicator 125, which may be included in or connected tothe computing unit 120. Such an indicator 125 may be a monitor, butthe indicator can also consist of one or more diode (s) that can indicate whenovertaking is appropriate and / or inappropriate. the indicator 125 may also be aor several speakers arranged to emit an audible signal10152025overtaking, and / or issue warning signs | to warn the driver of a dangerous orinappropriate overtaking.
    The procedure for facilitating overtaking planning of a vehicle in front140 includes that a calculation be made of how much speed is in front of itthe vehicle 140 drops in relation to its own vehicle 100 during a first stretch of road.
    This first stretch of road may, but does not necessarily have to, include oneuphill in some embodiments.
    Based on this calculation, an assessment can then be made to estimate whetherthe vehicle in front 140 can be overtaken on a second in frontroad sections, based on the calculated relative speed change betweenvehicles 100, 140 during the first section of road.
    The present second section of road can advantageously, according to certain embodimentsconsists of a road section of a similar nature to the first road section,for example, an uphill slope of similar or comparable slope and size. According toother embodiments, the first road section and the second road section may havedifferent character.
    A possible advantage of letting the first road section and / or the secondthe road section consists of a respective uphill slope is that certain vehicles 100, 140,particularly heavily loaded vehicles such as trucks, buses, trucks and the like oftengets a limited speed uphill, as previously stated.
    Figure 2A shows a schematic example of a scenario where a procedure in acalculation unit 120 in a vehicle 100 to facilitate planning of overtaking ofa vehicle 140 in front can be used.
    Both the own vehicle 100 and the vehicle in front 140 travel in onecommon direction of travel 105.
    The vehicle 100 has a sensor 130 for collecting data associated with onespeed change of the vehicle in front 140 during a firstroad section 210 in the direction of travel of the own vehicle 105.1015202510The first road section 210 may in some embodiments have a positive slope d irelative to the horizontal plane 110, i.e. constitutes an uphill slope.
    Based on this data collected, a speed change may occurin front of the vehicle 140 below the first road section 210 is calculated. Thisspeed change is then related to the speed change of the own vehicleduring the first road section 210.
    In some embodiments, the first path section 210 may be defined and the measurement ofthe relative speed change of the vehicles 100, 140 relative to each other is initiatedby the driver, by, for example, marking for the calculation unit 120 it wasthe first road section 210 begins and ends, respectively.
    In other embodiments, the computing unit 120 may be arranged to initializethe measurement of the relative speed change of the vehicles 100, 140 relative toeach other, and thus also define the first road section 210 then onevehicle 140 in front is detected within a certain distance in front of its ownvehicle 100.
    In further embodiments, the sensor 130 is arranged to identify the vehicle typea vehicle in front 140. In some embodiments, the sensor is 130arranged to identify in particular heavy traffic such as trucks, lorries, timber trucks,tanker, bus, etc. It will then be possible to activate the procedure according to then onefront vehicle 140 of this type is detected by the sensor.
    These embodiments have the advantage that one can filter out private car traffic, whichdoes not lose speed on uphill slopes in the same way as heavy traffic, and not innormally is provided with speed-limiting throttling that makes it impossiblespeeds above, for example, 90 km / h and do not have a tachograph installed,which monitors the journey and the speed of the vehicle (an official inspection can ingradually impose a fine if the speed limit has been exceeded during the journey).
    Furthermore, a second road section 220 is shown, which is located before, or afterfirst road section 210, calculated in the direction of travel 105 of the vehicles.1015202511The second road section 220 may in some embodiments have a positive slope ß irelative to the horizontal plane 110, i.e. constitutes an uphill slope.
    The slope oi on the first road section 210 and the slope ß on the secondthe road section 220 may be the same slope, similar to the slope within a certain range,or be completely different and / or unrelated to each other according to different embodiments. INsome embodiments are at least some of the respective slope d, ß in relationto the horizontal plane 110 equal to 0, that is, consists of a horizontalroad section. In some embodiments, at least one of the respective gradients is oi, ß irelation to the horizontal plane 110 less than 0, i.e. consists of onedownhill. As previously mentioned, however, it is a special advantage according to someembodiments to let the respective slope d, ß in relation to the horizontal plane 110be greater than 0, ie consist of a respective uphill slope.
    Figure 2B also shows a schematic example of a scenario where onemethod in a calculation unit 120 in a vehicle 100 to facilitate planning ofovertaking a vehicle in front 140 can be used. In Figure 2B, the vehicles have100, 140 arrived at the second road section 220.
    The vehicle behind 100 can now use the measured experiencethethe road section 210 to calculate whether an overtaking will be possible duringregarding relative speed change between the vehicles during the firstthe second road section 220.
    This is possible by estimating that the speed difference between the vehicles 100,140 below the second road section 220 will be the same as, or similar towith the already measured speed difference during the first road section 210,and with knowledge of the topographical and / or geographical conditionsalong the mileage of vehicles.
    Figure 3A shows a monitor 125 adjacent to the computing unit 120 thereinthe vehicle behind 100. In this illustrative example, it is highlightedthe second path section 220, a calculation having been made in the calculation unit 120,1015202512that the vehicle behind 100 has time to complete and complete the overtakingbefore the tricky intersection shown in the upper left corner of the figure.
    In some embodiments, the driver may be given an indication, when it is appropriate to startthe overtaking of vehicle in front 140 and / or when the overtaking is calculatedbe completed. This can in some cases be illustrated graphically as in Figure 3A, and / orwith a beep, a beep (green LED lights up when it's time to startovertaking,for example), a displayed text message or a recorded oneaudio message played in a speaker, etc. in various embodiments.
    Figure 3B also shows the monitor 125 in the vehicle behind 100. In thisexamples of illustration, which can be shown together with the example in Figure 3A,or as an alternative to this display, or together with another indicationthat overtaking is advisable.
    This example of information that can be displayed to the driver includes an indicationwhich shows when it is appropriate to start the overtaking, that is, where the otherroad section 220 begins. In this case, this indication is displayed in time (10 seconds), butit can just as easily be displayed in distance / length (meters), or by reference to onegeographical point ("start overtaking after the next right-hand curve"). Furthermore, this canindication in some embodiments is counted down as the vehicle 100 approachesthe beginning of the second road section 220. This information can also be communicated to the driverauditory in the form of a voice message communicating this information. An advantagewith communicating this information with a voice message may be to the drivercan focus on driving and does not have to look away from the road to read ona monitor 125.
    Furthermore, a decision basis in the form of information related to the overtakingdisplayed to the driver. Such information may include, for example, how long thedriving takes, the length of the overtaking in meters, the extra fuel consumption thatovertaking entails (in addition to fuel consumption if the overtaking does notcarried out) and the additional cost of this fuel, possibly also, orinstead, how much extra emissions the overtaking is forecast to give rise to.1015202513The latter can also in some embodiments be shown graphically in a bar, diagram,graph or similar. In other examples, the opposite may be, that is, how much extraemissions that are not released as a result of an inhibited overtaking are displayed. For examplethis can be displayed graphically in the form of a colored bar, for example green, the size of whichaccumulates / is reduced during the distance traveled by the vehicle 100. Correspondinglycan the extra fuel cost for overtaking, respectively the savings thatis done by inhibiting an overtaking illustrated in a colored stack,for example yellow. The colors green and yellow mentioned here are just examples of thispossible colors, any other color can be used alternatively.
    In some embodiments, where the driver's bonus is related to fuel consumptioncan, based on the current calculation algorithm for the bonus, added bonus impactdue to inhibited overtaking is shown, as an accumulated sum in kronor, orgraphically in a bar, chart, graph or similar.
    In some embodiments, even a graphical illustration of a switching diagram maycalculated to be suitable during the overtaking is shown to the driver, for conveniencehis shift during overtaking. This applies to vehicle 100 with manualgearbox. By proposing and displaying a shift schedule for the driver, it canit is avoided that he enters the wrong gear, which can lead to the vehicle 100 losingtraction. This is especially inappropriate just during overtaking, especially if overtakingis done on an uphill slope, as incorrect gear selection can lead to overtakingfail.
    Figure 3C also shows the monitor 125 in the vehicle behind 100. In thisFor example, the calculation unit 120 has come to the conclusion that overtaking ofvehicle 140 in front is not possible or suitable under the second section of road220.
    An indication that advises the driver not to overtake can then be displayed on the screen125, for example in the form of a warning text and / or a graphic figure withovertaking warning meaning. In some embodiments, the indicator 125 may be formedsomeby a diode, lamp or similar that lights up, or goes out. IN1015202514embodiments, a green light / diode lights up when overtaking is required / possible toimplement and / or a red light / diode when overtaking is not possible or appropriate.
    In some further embodiments, this information may also, or alternatively,also communicated auditorily in the form of an audio signal, which may also include onevoicemail, meaning that the driver is warned to overtake.
    In some embodiments, this information may also be further supplemented,for example by informing about another, present third section of road onwhich overtaking is advisable, and distance in time (minutes) or length (meters) tothis. An advantage of notifying the driver of such information is that he is then reassuredand become less likely to overtake despite being warned about it.
    Furthermore, according to certain embodiments, when the calculation unit 120 has determined thatan overtaking attempt will fail, or for other reasons is inappropriate,the driver is prevented from overtaking the vehicle in front 140,for example by power reduction on the engine when the vehicle 100 is swung out inovertaking lane, or changing lanes, according to certain embodiments. Thereby canhopeless overtaking attempts are prevented, leading to fuel savings.
    Figure 4 shows an example of a method in a calculation unit 120 in a vehicle100, to facilitate planning for overtaking a vehicle in front 140.
    In a first step, measurement data related to vehicle in front 140 can be collected tothe computing unit 120 according to certain embodiments. Such measurement data cancollected, for example, from one or more different sensors 130 in the vehicle 110 and canrefer to the configuration of the vehicle in front, such as the type of vehicle,and / or the speed of the vehicle in front. This collection of measurement data fromthe sensor 130 can, according to certain embodiments, be initiated by the driver bymark the start and end, respectively, of the first road section 210, over which a measurementis done.
    According to certain other embodiments, such data collection can be done continuouslyor periodically with a certain predetermined or configurable time interval, whengraphic data and / or geographical information of the current road section along101520253015the route in the direction of travel 105 indicates that a section of road that may be specialinteresting for measurement is achieved by the vehicle in front 140, such asfor example, an approaching uphill slope.
    However, according to certain embodiments, the sensor 130 may be arranged independentlycollect and send measurement data to the computing unit 120, over a wired orwireless interface as previously described. Such transmission of measurement data canfor example, is initiated by the sensor 130 when a vehicle in front 140 within onecertain distance from the own vehicle 100 is detected, and / or when avehicles 140 of a certain type of vehicle, such as, for example, trucks,detected within a certain distance from the own vehicle 100, possibly in someembodiments, in combination with insight into topographical, and / or geographicalinformation indicating, for example, uphill.
    Based on received measurement data related to the vehicle in front 140 canthe calculation unit 120 then calculates the speed of the vehicle in frontchange during the first road section 210.
    Furthermore, the computing unit 120 may collect speed-related information such asrefers to the own vehicle 100. This collection can be done for example fromthe vehicle's navigation system, GPS equipment or similar, or simply fromvehicle speedometer according to different embodiments. This speedrelated information may also include when a timing function startsthe vehicle 100 reaches the first road section 210, and terminates when the vehicle 100emerges from the first road section 210. The average speed of the vehicle canthen calculated when the length of the first road section can be extracted from either map.the information on this road section 210, GPS measurement, measurement based onthe vehicle's trip meter, or a distance measurement made with, for example, the vehicle'ssensor 130, to name just a few possible possibilities.
    Measurement data can be collected, for example, from a positioning system such as a GlobalPositioning System (GPS), Gallileo Global Navigation Satellite System (GNSS)GLObalnaja NAvigatsionnaja Sputnikovaja Sistema (GLONASS) or similar,which makes it possible to determine the existing position of the vehicle in the form of longitude,1015202516latitude and / or altitude. Furthermore, the route of the route, topographicalconditions and the like are determined. It can be used in some embodimentspreviously received and saved values from sensors, accelerometers, gyroand / or positioning systems which in some embodiments are stored in a memory, withtime statement.
    Based on the above-mentioned information, the speed of the own vehicle can be calculated.
    This calculated speed may include, for example, an average speed,a final speed when the far end of the first road section 210 is reached, adifference in speed between the entrance to, and the exit from, the first section of road210, or the like.
    A comparison between the respective speeds of the vehicles during the firstthe road section 210 can then be made. In some embodiments, the calculationunit 120 instead, or even calculate the relative speed difference betweenvehicles 100, 140 at the entrance to and exit from the first, respectivelyroad section 210. This information, how much speed the formerthe vehicle 140 drops below the first road section 210 in relation to how muchspeed the own vehicle 100 drops under the same road section 210 can thenbe used to forecast the possibility of re-driving the foregoingthe vehicle 140 under a second road section 220 in front.
    This assessment may also include detecting a previous secondroad section 220, during which the overtaking speed is assessed or calculated. Thisdetection of the second road section 220 may include a search among topographicaldata after a second road section 220 which exhibits a topographical characteristic such asrecalls, or is comparable to the measured first road section 210, according tocertain embodiments. According to certain embodiments, information regardingthe vehicle's destination and / or route is obtained, for example from the vehicle'snavigation system, which can be used to find a relevant second road section220, for example from a topographical or other point of view.1015202517When a second road section 220 in the direction of travel 105 of the vehicles has been detected and determinedthe calculation unit 120 can make a calculation and assessment of thethe drivability of the vehicle during this second road section 220.
    This assessment may be based on the collected relative velocity differencebetween the own vehicle 100 and the vehicle in front 140 below itfirst road section 210. If the own vehicle 100 has a relatively higher speedunder the first road section 210 than the vehicle in front 140, if necessarywith the addition of a hysteresis, or threshold value that may be, for examplevehicle type dependence, the vehicle 140 can be judged to be drivable.
    According to certain embodiments, the calculation of the vehicle in front mayreversibility also include an evaluation of the geographical locationrestrictions for overtaking, such as hidden exits, unattendedintersections, curves with poor visibility and the like. About such geographical limitationfound on the second road section 220, for example when analyzing geographical dataobtained from a memory, or from the vehicle's navigation system, GPS receiveror the like, a detour from overtaking on the relevant road section 220 mayissued and displayed to the driver.
    According to certain embodiments, the calculation of the vehicle in front mayreversibility also include an assessment of the formerthe traffic situation and an assessment of the meaningfulness of implementing itovertaking. According to some embodiments, this may involve obtainingtraffic information and / or detection of one or more accessibility restrictionsfactors in the direction of travel 105 of the vehicle, in front of the second road section 220. Exampleon such a limitation factor may be traffic accident, queuing,damaged or closed roadway, official control, bridge opening, railwayintersection, speed limit, road work, traffic lights, roundabout, fog, slipperiness,precipitation or similar. This information can also be combined withtime collection, or be time-controlled, such as that traffic volume / queue formation often has onetendency to increase in some well-known directions around cities in rush hour traffic.1015202518Such information related to a passability limiting factor in the vehicledirection of travel 105 can be obtained from either or a plurality of, for example, a trafficsurveillance service, traffic police, traffic radio, information database, weather serviceor similar.
    Detection of such a limitation factor can lead to a dissuasionfrom overtaking according to certain embodiments. An advantage of this is that you canavoid carrying out a costly overtaking from a fuel consumption point of view ”iunnecessarily ", if there is still a passability restriction such as onequeuing behind the hilltop in front.
    Furthermore, according to certain embodiments, an assessment of the vehicle's is also possibleestimated time of arrival at the destination is taken into account according to certainforms.
