Description

10 15 20 25 30 In 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-driven manned or unmanned means of transport, adapted for land-based geographical displacement.

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 limits throttling that makes speeds over a certain speed, for example 90 km / h, impossible, partly loses more traction than lighter vehicles on uphill slopes. This leads to two trucks on a straight line on a flat motorway section with good visibility and road conditions in rule drives at 90 km / h, ie the maximum possible speed for heavy traffic (on due to legal requirements in many countries, including Sweden). Uphill however, these vehicles may have different capacities or tensile strengths, for example on due to differences in engine power or vehicle load. A heavy vehicle behind with better traction uphill may then want to try to drive again vehicle in front, the problem for the driver is to know if this is possible before the uphill slope ends, as both vehicles will probably have the same speed downhill or on a flat road, ie where the driver still does not come by. The driver of the vehicle behind usually does not know that in front of the vehicle's performance and load conditions.

Another problem with overtaking is that the overtaking driver normally does not know what the road in front looks like after overtaking; for example there may be a hidden curve in front or exit that makes overtaking dangerous or inappropriate.

Another problem for the driver of the vehicle behind is that he does not know 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 or similar in front of the vehicle in front. A overtaking of this vehicle 10 15 20 25 then leads to increased fuel consumption without reaching the final destination faster, which makes overtaking essentially meaningless.

It can be stated that much still remains to be done to make it easier for one driver in an overtaking situation.

SUMMARY It is therefore an object of this invention to facilitate prior planning overtaking a vehicle in front, to solve at least some of the above specified problems and thus achieve a vehicle improvement.

According to a first aspect of the invention, this object is achieved by one procedure in a calculation unit in a vehicle to facilitate planning ahead overtaking a vehicle in front. The method involves data collection associated with a change in speed of the vehicle in front as a whole first road section in the direction of travel of the own vehicle, from a sensor. The procedure also includes calculation of the speed change of the foregoing the vehicle under the first road section. Furthermore, the method comprises collecting speed-related information associated with your own vehicle. The procedure also includes the collection of route-related data, associated with a presently other road sections in the direction of travel of the own vehicle. The procedure also includes calculation of the drivability of the vehicle in front of the present second section of road, based on the calculated speed the change of the vehicle in front, the collected speed related information associated with the own vehicle and collected route-related data, associated with the preceding second section of the road.

The method also includes presentation of the calculation made therefrom the drivability of the vehicle in front of the driver, in order to thereby facilitate his planning before overtaking the vehicle in front. 10 15 20 25 30 According to a second aspect of the invention, this object is achieved by one calculation unit in a vehicle to facilitate planning before overtaking a vehicles in front. The calculation unit comprises a receiver arranged to collect data associated with a speed change of the foregoing the vehicle, during a first road section in the direction of travel of the own vehicle, from a sensor. The calculation unit also comprises a processor circuit, arranged to calculate the speed change of the vehicle in front. Processor- the circuit is also arranged to collect speed related information associated with their own vehicle and also arranged to collect route-related data, associated with a pre-existing second road section of the own vehicle direction of travel. In addition, the processor circuit is arranged to calculate the the reversibility of the vehicle on the second road section in front, based on the calculated velocity change of the foregoing the vehicle, the collected speed-related information associated with it own vehicle and collected route-related data associated with it in front of the second road section. Furthermore, the calculation unit comprises a communication connection, arranged to communicate data representing it made the calculation of the drivability of the vehicle in front to a indicator.

By measuring the actual values of speed change for a person in front vehicles during a first road section, this information can be used to calculate one in front of other road sections. This way of assessing overtaking is more and forecast whether a overtaking of the vehicle is possible during reliable than assessments based solely on map data and / or instantaneous relative speed between vehicles. This gives a more reliable assessment of whether the vehicle in front is drivable under a certain section of road, which provides a safer driving of the vehicle, but also saves fuel and thus also money by making unnecessary and / or hopeless overtaking attempts possible avoided. By avoiding unsuccessful overtaking attempts, the environmental the load. In addition, the road's passability for other road users, then it the overtaking lane is blocked by a vehicle that does not pass one another vehicle. 10 15 20 25 Other benefits and additional features will become apparent from the following details description of the invention.

DETAILED DESCRIPTION OF THE INVENTION The invention is defined as a method and a calculation unit for facilitate the planning of overtaking of a vehicle in front, which can realized in any of the embodiments described below. This invention can, however, be implemented in many different forms and should not be seen as limited by those the embodiments described herein, which are instead intended to illustrate and illustrate various aspects of the invention.

Additional aspects and features of the invention may become apparent from it the following detailed description when considered in connection with the attached the figures. However, the figures are only to be considered as examples of different embodiments of the invention and should not be construed as limiting the invention, which is limited only by the appended claims. Furthermore, the figures not necessarily to scale and are, unless otherwise specifically stated, intended to conceptually illustrate aspects of the invention.

Figure 1A shows a vehicle 100 traveling in a direction of travel 105 on a horizontal base 110 towards a final destination. The vehicle 100 has a sensor 130, located for example inside the wheelhouse behind the windscreen so that objects and / or vehicles in front of the own vehicle 100 can be detected. You can also imagine others locations, for example, the sensor 130 may be located on the outside of the wheelhouse or roofs according to certain embodiments, or for example on the vehicle's bumper or chassis. However, it is an advantage to have the sensor 130 located inside the wheelhouse when it where is relatively protected from dirt, dust and sleet, which has a beneficial effect on sensor function, reliability and service life. to some extent the 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. 10 15 20 25 The sensor 130 may comprise, or consist of, for example, a radar meter, a Laser meters such as a Light Detection And Ranging (LIDAR), sometimes also called LADAR or laser radar, a camera such as a Time of-Flight camera (ToF camera), a rangefinder based on ultrasonic waves or similar device configured for distance assessment.

A LIDAR is an optical measuring instrument that measures the properties of reflected light to find the distance (and / or other properties) of a remote object. The technology is very similar to radar, (Radio Detection and Ranging), but instead of radio waves, light is used. Typically, you measure the distance to an object by measuring the time delay between a transmitted laser pulse and the registered one the reflex.

A Time-of-Flight camera (ToF camera) is a camera system that takes a sequence of images and measures a distance to an object based on the known the speed of light, by measuring the time required for a light signal between the camera and 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 contrast to 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 one in front, vehicles and through this wireless communication obtain related to it speed 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 example Furthermore, the vehicle 100 may comprise, or consist of, a plurality of sensors 130 of either the same type of sensor 130 or different types of sensors 130 according to different embodiments. An advantage of having a plurality of sensors 130 is that you can then make more reliable assessments of distance / speed and / or identification of vehicle in front or vehicle type. 10 15 20 25 It may further be an advantage to use sensors 130 that already exist mounted in the vehicle 100 for other purposes, such as warning the driver to the distance to the vehicle in front is too small, etc .; collision detector, or other similar sensor 130. This can avoid fitting a special sensor 130 for this particular invention, leading to lower manufacturing costs and a better 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 is arranged to communicate with the sensor 130 over a wired or wireless interfaces according to different embodiments.

The wired interface may, for example, be based on any of the following technologies: Controller Area Network (CAN), Media Oriented Systems Transport (MOST), Ethernet, (USB), RS232, FireWire, Thunderbolt, to name just a few possibilities.

Universal Serial Bus Serial For example, the wireless interface may be based on one of the following technologies: Global System for Mobile Communications (GSM), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Code Division Access (CDMA), (CDMA 2000), Time Division Synchronous 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 / or Near Field Communication, (NFC), according to different embodiments.

A second vehicle 140 in front drives in front of its own vehicle 100. In the vehicle 100, there is further provided an indicator 125, which may be included in or connected to the computing unit 120. Such an indicator 125 may be a monitor, but the indicator can also consist of one or more diode (s) that can indicate when overtaking is appropriate and / or inappropriate. the indicator 125 may also be a or several speakers arranged to emit an audible signal 10 15 20 25 overtaking, and / or issue warning signs | to warn the driver of a dangerous or inappropriate overtaking.

The procedure for facilitating overtaking planning of a vehicle in front 140 includes that a calculation be made of how much speed is in front of it the 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 one uphill in some embodiments.

Based on this calculation, an assessment can then be made to estimate whether the vehicle in front 140 can be overtaken on a second in front road sections, based on the calculated relative speed change between vehicles 100, 140 during the first section of road.

The present second section of road can advantageously, according to certain embodiments consists 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 to other embodiments, the first road section and the second road section may have different character.

A possible advantage of letting the first road section and / or the second the 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 often gets a limited speed uphill, as previously stated.

Figure 2A shows a schematic example of a scenario where a procedure in a calculation unit 120 in a vehicle 100 to facilitate planning of overtaking of a vehicle 140 in front can be used.

Both the own vehicle 100 and the vehicle in front 140 travel in one common direction of travel 105.

The vehicle 100 has a sensor 130 for collecting data associated with one speed change of the vehicle in front 140 during a first road section 210 in the direction of travel of the own vehicle 105. 10 15 20 25 10 The first road section 210 may in some embodiments have a positive slope d i relative to the horizontal plane 110, i.e. constitutes an uphill slope.

Based on this data collected, a speed change may occur in front of the vehicle 140 below the first road section 210 is calculated. This speed change is then related to the speed change of the own vehicle during the first road section 210.

In some embodiments, the first path section 210 may be defined and the measurement of the relative speed change of the vehicles 100, 140 relative to each other is initiated by the driver, by, for example, marking for the calculation unit 120 it was the first road section 210 begins and ends, respectively.

In other embodiments, the computing unit 120 may be arranged to initialize the measurement of the relative speed change of the vehicles 100, 140 relative to each other, and thus also define the first road section 210 then one vehicle 140 in front is detected within a certain distance in front of its own vehicle 100.

In further embodiments, the sensor 130 is arranged to identify the vehicle type a vehicle in front 140. In some embodiments, the sensor is 130 arranged 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 one front vehicle 140 of this type is detected by the sensor.

These embodiments have the advantage that one can filter out private car traffic, which does not lose speed on uphill slopes in the same way as heavy traffic, and not in normally is provided with speed-limiting throttling that makes it impossible speeds 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 in gradually 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 after first road section 210, calculated in the direction of travel 105 of the vehicles. 10 15 20 25 11 The second road section 220 may in some embodiments have a positive slope ß i relative 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 second the 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. IN some embodiments are at least some of the respective slope d, ß in relation to the horizontal plane 110 equal to 0, that is, consists of a horizontal road section. In some embodiments, at least one of the respective gradients is oi, ß i relation to the horizontal plane 110 less than 0, i.e. consists of one downhill. As previously mentioned, however, it is a special advantage according to some embodiments to let the respective slope d, ß in relation to the horizontal plane 110 be greater than 0, ie consist of a respective uphill slope.

Figure 2B also shows a schematic example of a scenario where one method in a calculation unit 120 in a vehicle 100 to facilitate planning of overtaking a vehicle in front 140 can be used. In Figure 2B, the vehicles have 100, 140 arrived at the second road section 220.

The vehicle behind 100 can now use the measured experience the the road section 210 to calculate whether an overtaking will be possible during regarding relative speed change between the vehicles during the first the 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 to with the already measured speed difference during the first road section 210, and with knowledge of the topographical and / or geographical conditions along the mileage of vehicles.

Figure 3A shows a monitor 125 adjacent to the computing unit 120 therein the vehicle behind 100. In this illustrative example, it is highlighted the second path section 220, a calculation having been made in the calculation unit 120, 10 15 20 25 12 that the vehicle behind 100 has time to complete and complete the overtaking before 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 start the overtaking of vehicle in front 140 and / or when the overtaking is calculated be completed. This can in some cases be illustrated graphically as in Figure 3A, and / or with a beep, a beep (green LED lights up when it's time to start overtaking, for example), a displayed text message or a recorded one audio message played in a speaker, etc. in various embodiments.

Figure 3B also shows the monitor 125 in the vehicle behind 100. In this examples of illustration, which can be shown together with the example in Figure 3A, or as an alternative to this display, or together with another indication that overtaking is advisable.

This example of information that can be displayed to the driver includes an indication which shows when it is appropriate to start the overtaking, that is, where the other road section 220 begins. In this case, this indication is displayed in time (10 seconds), but it can just as easily be displayed in distance / length (meters), or by reference to one geographical point ("start overtaking after the next right-hand curve"). Furthermore, this can indication in some embodiments is counted down as the vehicle 100 approaches the beginning of the second road section 220. This information can also be communicated to the driver auditory in the form of a voice message communicating this information. An advantage with communicating this information with a voice message may be to the driver can focus on driving and does not have to look away from the road to read on a monitor 125.

Furthermore, a decision basis in the form of information related to the overtaking displayed to the driver. Such information may include, for example, how long the driving takes, the length of the overtaking in meters, the extra fuel consumption that overtaking entails (in addition to fuel consumption if the overtaking does not carried out) and the additional cost of this fuel, possibly also, or instead, how much extra emissions the overtaking is forecast to give rise to. 10 15 20 25 13 The 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 extra emissions that are not released as a result of an inhibited overtaking are displayed. For example this can be displayed graphically in the form of a colored bar, for example green, the size of which accumulates / is reduced during the distance traveled by the vehicle 100. Correspondingly can the extra fuel cost for overtaking, respectively the savings that is done by inhibiting an overtaking illustrated in a colored stack, for example yellow. The colors green and yellow mentioned here are just examples of this possible colors, any other color can be used alternatively.

In some embodiments, where the driver's bonus is related to fuel consumption can, based on the current calculation algorithm for the bonus, added bonus impact due to inhibited overtaking is shown, as an accumulated sum in kronor, or graphically in a bar, chart, graph or similar.

In some embodiments, even a graphical illustration of a switching diagram may calculated to be suitable during the overtaking is shown to the driver, for convenience his shift during overtaking. This applies to vehicle 100 with manual gearbox. By proposing and displaying a shift schedule for the driver, it can it is avoided that he enters the wrong gear, which can lead to the vehicle 100 losing traction. This is especially inappropriate just during overtaking, especially if overtaking is done on an uphill slope, as incorrect gear selection can lead to overtaking fail.

Figure 3C also shows the monitor 125 in the vehicle behind 100. In this For example, the calculation unit 120 has come to the conclusion that overtaking of vehicle 140 in front is not possible or suitable under the second section of road 220.

An indication that advises the driver not to overtake can then be displayed on the screen 125, for example in the form of a warning text and / or a graphic figure with overtaking warning meaning. In some embodiments, the indicator 125 may be formed some by a diode, lamp or similar that lights up, or goes out. IN 10 15 20 25 14 embodiments, a green light / diode lights up when overtaking is required / possible to implement 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 one voicemail, 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 on which overtaking is advisable, and distance in time (minutes) or length (meters) to this. An advantage of notifying the driver of such information is that he is then reassured and become less likely to overtake despite being warned about it.

Furthermore, according to certain embodiments, when the calculation unit 120 has determined that an 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 in overtaking lane, or changing lanes, according to certain embodiments. Thereby can hopeless overtaking attempts are prevented, leading to fuel savings.

Figure 4 shows an example of a method in a calculation unit 120 in a vehicle 100, 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 to the computing unit 120 according to certain embodiments. Such measurement data can collected, for example, from one or more different sensors 130 in the vehicle 110 and can refer 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 from the sensor 130 can, according to certain embodiments, be initiated by the driver by mark the start and end, respectively, of the first road section 210, over which a measurement is done.

According to certain other embodiments, such data collection can be done continuously or periodically with a certain predetermined or configurable time interval, when graphic data and / or geographical information of the current road section along 10 15 20 25 30 15 the route in the direction of travel 105 indicates that a section of road that may be special interesting for measurement is achieved by the vehicle in front 140, such as for example, an approaching uphill slope.

However, according to certain embodiments, the sensor 130 may be arranged independently collect and send measurement data to the computing unit 120, over a wired or wireless interface as previously described. Such transmission of measurement data can for example, is initiated by the sensor 130 when a vehicle in front 140 within one certain distance from the own vehicle 100 is detected, and / or when a vehicles 140 of a certain type of vehicle, such as, for example, trucks, detected within a certain distance from the own vehicle 100, possibly in some embodiments, in combination with insight into topographical, and / or geographical information indicating, for example, uphill.

Based on received measurement data related to the vehicle in front 140 can the calculation unit 120 then calculates the speed of the vehicle in front change during the first road section 210.

Furthermore, the computing unit 120 may collect speed-related information such as refers to the own vehicle 100. This collection can be done for example from the vehicle's navigation system, GPS equipment or similar, or simply from vehicle speedometer according to different embodiments. This speed related information may also include when a timing function starts the vehicle 100 reaches the first road section 210, and terminates when the vehicle 100 emerges from the first road section 210. The average speed of the vehicle can then 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 on the vehicle's trip meter, or a distance measurement made with, for example, the vehicle's sensor 130, to name just a few possible possibilities.

Measurement data can be collected, for example, from a positioning system such as a Global Positioning 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, 10 15 20 25 16 latitude and / or altitude. Furthermore, the route of the route, topographical conditions and the like are determined. It can be used in some embodiments previously received and saved values from sensors, accelerometers, gyro and / or positioning systems which in some embodiments are stored in a memory, with time 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, a difference in speed between the entrance to, and the exit from, the first section of road 210, or the like.

A comparison between the respective speeds of the vehicles during the first the road section 210 can then be made. In some embodiments, the calculation unit 120 instead, or even calculate the relative speed difference between vehicles 100, 140 at the entrance to and exit from the first, respectively road section 210. This information, how much speed the former the vehicle 140 drops below the first road section 210 in relation to how much speed the own vehicle 100 drops under the same road section 210 can then be used to forecast the possibility of re-driving the foregoing the vehicle 140 under a second road section 220 in front.

This assessment may also include detecting a previous second road section 220, during which the overtaking speed is assessed or calculated. This detection of the second road section 220 may include a search among topographical data after a second road section 220 which exhibits a topographical characteristic such as recalls, or is comparable to the measured first road section 210, according to certain embodiments. According to certain embodiments, information regarding the vehicle's destination and / or route is obtained, for example from the vehicle's navigation system, which can be used to find a relevant second road section 220, for example from a topographical or other point of view. 10 15 20 25 17 When a second road section 220 in the direction of travel 105 of the vehicles has been detected and determined the calculation unit 120 can make a calculation and assessment of the the drivability of the vehicle during this second road section 220.

This assessment may be based on the collected relative velocity difference between the own vehicle 100 and the vehicle in front 140 below it first road section 210. If the own vehicle 100 has a relatively higher speed under the first road section 210 than the vehicle in front 140, if necessary with the addition of a hysteresis, or threshold value that may be, for example vehicle type dependence, the vehicle 140 can be judged to be drivable.

According to certain embodiments, the calculation of the vehicle in front may reversibility also include an evaluation of the geographical location restrictions for overtaking, such as hidden exits, unattended intersections, curves with poor visibility and the like. About such geographical limitation found on the second road section 220, for example when analyzing geographical data obtained from a memory, or from the vehicle's navigation system, GPS receiver or the like, a detour from overtaking on the relevant road section 220 may issued and displayed to the driver.

According to certain embodiments, the calculation of the vehicle in front may reversibility also include an assessment of the former the traffic situation and an assessment of the meaningfulness of implementing it overtaking. According to some embodiments, this may involve obtaining traffic information and / or detection of one or more accessibility restrictions factors in the direction of travel 105 of the vehicle, in front of the second road section 220. Example on such a limitation factor may be traffic accident, queuing, damaged or closed roadway, official control, bridge opening, railway intersection, speed limit, road work, traffic lights, roundabout, fog, slipperiness, precipitation or similar. This information can also be combined with time collection, or be time-controlled, such as that traffic volume / queue formation often has one tendency to increase in some well-known directions around cities in rush hour traffic. 10 15 20 25 18 Such information related to a passability limiting factor in the vehicle direction of travel 105 can be obtained from either or a plurality of, for example, a traffic surveillance service, traffic police, traffic radio, information database, weather service or similar.

Detection of such a limitation factor can lead to a dissuasion from overtaking according to certain embodiments. An advantage of this is that you can avoid carrying out a costly overtaking from a fuel consumption point of view ”i unnecessarily ", if there is still a passability restriction such as one queuing behind the hilltop in front.

Furthermore, according to certain embodiments, an assessment of the vehicle's is also possible estimated time of arrival at the destination is taken into account according to certain forms. In this case, the calculation unit 120 can perform a calculation of the vehicle 100 are expected to arrive before or after the estimated and / or agreed time of arrival, and if the calculation indicates that the vehicle 100 is ahead of schedule, that is say is expected to arrive before the agreed arrival time, one can advise against overtaking is issued, according to certain embodiments. In this case, overtaking can be avoided if these result in the driver of the vehicle 100 having to wait at the destination, who can be, for example, a ferry terminal, or a loading dock where the staff has not yet arrived.

Furthermore, the calculation unit 120, when it is determined whether / that the present vehicle 140 can / should / should be overtaken under the second road section 220, send one signal to the indicator 125 to present the result of the estimate made of the drivability of the vehicle in front of the driver, in order thereby facilitate the planning of the overtaking of the vehicle in front 140.

This can be done, for example, by lighting a green light, a recorded one voicemail calls for overtaking and / or information related to it the resulting situation is displayed on a screen.

The driver can then, according to certain embodiments, use this information as decision basis for assessing whether an overtaking should be made or not. It can of course be such that the driver sees other reasons not to overtake, 10 15 20 25 19 such as, for example, that a third, vehicle behind has already started one overtaking your own vehicle 100; or that the vehicle in front 140 is part of a collaboration with one's own vehicle 100, such as one vehicle trains in so-called platooning; or that the driver simply does not want to drive again just because it is technically possible.
