    TECHNICAL FIELD This document describes a procedure and a device in a vehicle as well as a procedure and a device in connection with a fellow road user of the vehicle. More specifically, a mechanism is provided for identifying a surrounding vehicle which has an increased need for attention as a result of a safety-critical driving behavior of the driver of this vehicle.
    BACKGROUND In a traffic situation, it sometimes happens that some surrounding drivers in front of their vehicle in an unpredictable, irrational way, or simply Icor careless for various reasons.
    Examples of this can be drivers who suddenly change lanes without using a correction indicator, drivers who use the inner lane as a overtaking lane on a motorway, drivers who take a detour over solid road markings or drivers who drive slalom with the vehicle between two lanes.
    As a result, fellow road users are often forced to adapt their 'corning to the carelessly forward vehicle with hard braking and / or rapid evasive maneuvers as a result. In any case, the result can be a traffic accident. A fellow road user of the careless driver must, however, have supervision over surrounding vehicles both in front and behind and on the sides of his own vehicle, as well as over traffic signs, lanes / lanes, etc., and may therefore have difficulty distinguishing and identifying the careless driver from the crowd. by other, more predictable road users. The driver must therefore critically examine all surrounding vehicles and may then miss the vehicle that is most at risk of unforeseen maneuvers.
    An existing solution to this problem is to mark certain risk vehicles, for example vehicles where the driver trains. These drivers are often overly cautious and hesitant in their crossover style and can therefore cause misunderstanding for fellow road users. The problem with the existing sign 30 sold on these vehicles is that it is usually only visible to the vehicle closest to the rear. In an intersection or roundabout, the training vehicle may, by hesitant and unclear action, cause misinterpretation by a fellow road user who only sees this vehicle from the front or from the side.
    JP 2012168811 shows a system for warning the driver of a vehicle behind the risk of colliding with his own vehicle. The system triggers a yarning when the own vehicle is close to another, forward-facing vehicle. Thereby, an underlying road user 2 is warned in the event of an imminent collision risk for his own vehicle and a series crash, for example, can be avoided. The problem with this solution is that it does not help the driver to identify other drivers who exhibit risky behavior in traffic.
    US 7411485 discloses a system for visually warning the driver when he leaves the lane in which the vehicle is driven. The system is activated when the driver shows signs of fatigue. This solution is about warning the driver of his own reckless driving as a result of fatigue or inattention, not about warning fellow road users of this. Nor does this solution make it possible to identify other drivers with risky behavior in traffic.
    US 8031063 discloses a system which determines if the own vehicle makes an unintentional lane change, and warns the driver when this occurs. No yarning Ors for fellow road users. Nor does this solution make it possible to identify other drivers with risky behavior in traffic.
    It can be stated that much remains to be done to facilitate a road user's detection and identification of careless or dangerous fellow road users in traffic.
    SUMMARY It is therefore an object of this invention to be able to solve at least some of the above problems and make it easier for a fellow road user to identify a surrounding vehicle with an increased need for attention.
    According to a first aspect of the invention, this targeting is achieved by a method in a vehicle, in order to determine and inform a fellow road user that the vehicle has an increased need for attention. The method comprises detecting the number of safety-critical operations in the vehicle over a period of time. Furthermore, the method comprises a comparison between the detected number of security-critical operations with one or more spruce values. The method also includes sending a message to the fellow road user to indicate an increased need for attention, as the detected number of safety-critical operations exceeds the said one or more spruce response values.
    According to a second aspect of the invention, this targeting is achieved by a device in a vehicle, arranged to determine and inform a fellow road user that the vehicle has an increased need for attention. The device comprises a detector, arranged to detect a safety-critical operation in the vehicle. Furthermore, the device comprises a processor circuit, arranged to receive an indication of a safety-critical operation of the driver from the detector, and to calculate the number of safety-critical operations of the driver during a period of time. The processor circuit is also arranged to compare the detected number of security-critical operations with one or more spruce values. The processor circuit is also arranged to send a control signal to trigger a transmission of a message to the fellow road user to indicate an increased need for attention from the vehicle, as the number of detected safety-critical operations exceeds the said one or more spruce values.
    According to a third aspect of the invention, this object is achieved by a method for drawing the attention of a fellow road user to a vehicle which has an increased need for attention. The method comprises receiving a message from the vehicle indicating an increased need for attention of the vehicle. Furthermore, the method also includes an indication of the vehicle which has an increased need for attention.
    According to a fourth aspect of the invention, this object is achieved by a device for drawing the attention of a fellow road user to a vehicle which has an increased need for attention.
    Such a device comprises a receiver, arranged for receiving a warning message from the vehicle, which indicates an increased need for attention. The device also comprises an indicator, arranged to indicate the vehicle which has an increased need for attention. By defining traffic hazardous vehicle drivers, or vehicle drivers with an increased need for attention, and enabling a fellow road user to identify this vehicle, the fellow road users' attention can be directed towards the largest risk objects in the surrounding traffic, which can help reduce the risk of a traffic accident. This is an advantage for the driver in the dangerous vehicle, as for surrounding road users. This achieves a safer road user environment and safer vehicles for the vehicles involved.
    Other advantages and additional features will be apparent from the following detailed description.

    DETAILED DESCRIPTION Embodiments of the invention include methods and devices which may be realized according to any of the examples described below. However, this invention can be practiced in many different forms and should not be construed as limited by the embodiments described herein, which are intended to illustrate and obscure various aspects.
    Additional aspects and features of the invention may become apparent from the following detailed description when considered in conjunction with the accompanying figures. However, the figures are to be considered only as examples of various embodiments of the invention and are not to be construed as limiting the invention, which is limited only by the appended claims. Furthermore, the figures are not necessarily to scale, and are, unless otherwise specifically indicated, intended to conceptually illustrate aspects of the invention.
    Figure 1A shows a vehicle 100, adapted for motor-driven driving in, inter alia, a first direction of travel 105. For example, but not necessarily, the vehicle 100 may be a truck, a lorry, a truck, a bus, a car, a tractor, a motorcycle, or similar land-based manned or unmanned means of subsistence. Further, a fellow road user 110 is illustrated to the vehicle 100. In the illustrated example, the fellow road user 110 is constituted by a truck; however, this is just an arbitrary example. The fellow road user 110 may be, for example, one of the above-mentioned vehicle types, or a pedestrian, a cyclist or the like.
    According to one embodiment, a vehicle 100 is identified which is being driven carelessly, or which the fellow road user 110 of other shells has reason to be extra observant of. Such a shell may be, for example, that the driver shows signs of fatigue or inattention, that the driver has a new driver's license, that -The product is often involved in traffic accidents, that the vehicle's fuel is about to run out (which can cause either the vehicle 100 to stop suddenly , or that the driver makes a late lane change to get to an exit where there is a gas station), or the like. This identified vehicle 100 is suitably damaged in front of the road user 110. The road user 110 can be alerted by, for example, an audible signal, a rust message, visually by marking on a monitor or on the windscreen or on a head up display facing the windscreen, on which the vehicle 100 is marked as an increased risk. In this way, the fellow road user 110 can be noticed and made aware of the increased risk posed by the vehicle 100, with his current driver.
    The fellow road user 110 can thereby be helped to quickly identify and distinguish vehicles 100 which have a driver with an unpredictable or dangerous crossing style. By becoming aware of the increased accident risk posed by the vehicle 100, the passenger 110 can focus on this vehicle 100 and adapt his actions at an early stage, for example by keeping an extra long distance to the vehicle 100, to redirect the vehicle 100 to a wide, slow down your own speed, etc. As a result, an accident can be avoided, and / or the consequences of an accident can be reduced. This is an advantage, not only for the fellow road user 110 but also for the goods in the vehicle 100, as well as for other surrounding road users.
    A certain vehicle 100 can be driven by different drivers on different occasions and according to certain embodiments the driver of the vehicle is therefore identified, for example by unloading the digital tachograph card in vehicles in commercial traffic; unloading the driver's license card; in that different predefined drivers for the vehicle 100 have different keys or for example short radio transmitters (sometimes called tags) to identify them as individual drivers in the vehicle. In some embodiments, one may even consider face identification of the driver with a camera provided for this in the vehicle 100, identification of the driver's fingerprint with a fingerprint laser which may, for example, be built into the steering wheel or gear lever, retina scanner identifying the driver's eyes, or similar biometric identification method. The identification of the -Ware can, in addition to, for example, set the seat, steering wheel inclination and other driver-related parameters, 5N / en be linked to a stored history of the driver's chord data according to certain forms of performance. This enables 5N / an individual adaptation of the threshold value for different safety-critical operations in the vehicle 100, based on historical data about an identified driver in the vehicle 100.
    The term "vehicle 100 which has an increased need for attention" is used hate- sometimes sy10 anonymously with the term "driver who has an increased need for attention".
    Figure 1B shows the same scenario with the vehicle 100 and the fellow road user 110 as damaged in Figure 1A, but viewed from a bird's eye view. The driver of the vehicle 100 has crossed the corphal line several times during a certain time period. According to one embodiment of the invention, the product of this vehicle 100 can be categorized as a vehicle with a heightened need for attention. A message indicating an increased need for attention of the vehicle 100 can be sent to the fellow road user 110 according to certain embodiments, but a wireless interface.
    This wireless interface may be based on, for example, any of the following technologies for vehicle-to-vehicle communication: 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), LTE-Advanced; 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), WLAN, Bluetooth and / or Near Field Communication, ( NFC), or similar communication technology based on radio communication according to different embodiments, possibly via a base station or the like.
    Figure 2 shows an example of a vehicle interior of the vehicle 100. The vehicle 100 includes a device 200, for determining that the vehicle 100 has an increased need for attention due to detected safety-critical operations in the vehicle 100. The device 200 is also arranged to notify a fellow road user 110 that the vehicle 100 has an increased need for attention, via the sending of a wireless warning message. The vehicle 100 also comprises one or more detectors 2 of the same, similar or different type, arranged to detect a safety-critical operation in the vehicle 100. For example, the detector 210 may be performed by a camera directed towards the driver's eyes, and / or a vehicle sensor such as steering wheel angle. gear sensor and / or accelerometer. More examples of different detectors 210 that can cooperate in the vehicle 100 are given further down.
    The safety-critical operation may include, for example, changing lanes without using direction indicators; lane change without the driver looking in the rearview mirror; as the driver has his eyes closed longer than a predetermined period of time; The driver looks at something other than the windscreen / rear-view mirrors 10 longer than a certain period of time; then the driver is in a different file than what the vehicle's (GPS) navigator indicates (and therefore may need a quick file change soon); the vehicle's industry is about to run out; rerouting of another vehicle on the inside; slalom making between other vehicles in different lanes; when the distance in time to the vehicle in front is less than three seconds; when the driver activates his mobile phone without using hands-free while driving; as the vehicle's tachograph indicates that the maximum permitted short time without a break / day rest is about to be exceeded / has been exceeded (if the vehicle 100 has a tachograph); when the driver shortens the vehicle 100 without a break for a longer time than a certain spruce value, for example 4 hours; when the speed limit is exceeded, or exceeded by more than, for example, 10%; when a fatigue warning post in the vehicle 100 indicates that the driver is tired; when an alcohol feeder in the vehicle 100 indicates that the driver has drunk alcohol; when the vehicle 100 stops on the motorway; when the vehicle 100 backs on the motorway; when the vehicle 100 is to undergo winter trapping on the national road; or other similar act. This list is not exhaustive but can rather be seen as an example of various inappropriate actions during 'A detector 210 arranged to detect that the driver is changing lanes without looking in the rearview mirror, or to detect that the driver has his eyes closed for a longer predetermined period of time can be constituted by a camera or the like. A detector 210 arranged to detect when the driver is making a lane change without using direction indicators may comprise one or more sensors may detect the vehicle's position in the lane, or when the driver is in a different lane than what the vehicle's (GPS) navigator indicates. A detector 210 arranged to detect when the distance in time to the vehicle in front is less than three seconds may comprise, for example, a distance feeder, such as, for example, a laser distance feeder which can measure the distance to the vehicle in front. The detector 210 may further comprise, for example, a fatigue warning post in the vehicle 100, which may indicate that the driver is drunk, or an alcohol feeder in the vehicle 100, which may indicate that the product has been drinking alcohol. When the detector / sensors 210 have detected a security-critical operation, a message about this is sent to the device 200, via a wireless or wired interface. Such wired communication can be made, for example, via the vehicle's communication bus, which can be constituted by one or more of a cable; a data bus, such as a CAN bus (Controller Area Network bus), a MOST bus (Media Oriented Systems Transport), or any other bus configuration.
    The device 200 and the detector / sensors 210 may also, or alternatively, be arranged for wireless communication over a wireless interface according to certain embodiments, for example any of the wireless interfaces listed above.
    The device 200 can then calculate the number of detected safety-critical operations of the driver over a period of time and compare the resulting number with a spruce value. If the threshold value is exceeded, the device 200 can send a control signal to trigger a transmission of a message to the fellow road user 110 to indicate an increased need for attention for the vehicle 100, via a wireless interface, for example through a transmitter.
    Furthermore, according to certain embodiments, the device 200 can be arranged to determine that the vehicle 100 in front of the -Waren has an increased need for attention d-the Ware training, regardless of whether this takes place in a cross school or in a private Training run. This can be done, for example, by the driver himself marking that the vehicle 100 has an increased need for attention as a result of training driving. Alternatively, a unloading of the driver's driver's card can be done, and the absence of driver's driver's license cards can be interpreted as practice driving or illegal driving in the vehicle 100. The fact that the driver of the vehicle does not have a valid driver's card can in itself be a concern for fellow road users 110.
    According to certain embodiments, the device 200 may determine that the driver has a cork card that has been issued less time ago than a second spruce value. This second spruce value can be a number of 5r, for example 1 5r, 2 5r, 5 5r; or a multiple of these, or a value between these values. This driver with a new driver's license has more limited experience than 35 other drivers. Furthermore, the device 200 can also determine that the driver is older than a third spruce value. This third spruce value can be, for example, 70 years, 75 years, 80 years, or a value in between. Older people over these ages are often overrepresented in accident statistics.
    The device 200 can also determine if the driver has previously had his driver card revoked; for example, by identifying -Waren according to the driver card, sending a request to a database if the driver has had his driver card revoked earlier and determining that the vehicle 100 in front of the driver has an increased need for attention in this case. The device 200 can also send a request to the car register and determine whether the vehicle 100 is prohibited from crossing, and / or is wanted. A vehicle 100 with a ban on crossing as a result of failing in the car inspection can pose a safety risk in traffic.
    The device 200 can also in certain embodiments determine that the driver has a number of injury-free years which is below a fourth spruce value. This fourth spruce value can be, for example, 1 year, 2 years, 3 years, 4 years, or the like. The device 200 can, for example, identify the goods via the card, send a request to a database, for example belonging to the driver's insurance company, and determine that the vehicle 100 in front of the goods has an increased need for attention.
    In some embodiments, the device 200 may also detect that the vehicle 100 is an emergency vehicle during emergency response and therefore has an increased need for attention as these have a right and sometimes even an obligation to violate ordinary traffic rules, for example regarding speed limitation. The device 200 can thereby detect when the driver activates sirens / blue lights in the vehicle 100 according to certain embodiments.
    The device 200 can also in certain embodiments detect other vehicle types with a deviating grain pattern, such as mail vans (which often stop at letterboxes), garbage trucks (which often stop in front of properties and have garbage cans that jump out of the vehicle 100), cleaning vehicles such as e.g. salt truck / plow truck (which may have to move over files, suddenly stop and turn, etc. to get bait snO), and / or detect that a vehicle 100 that is not a bus / taxi is running in a bus lane (then this road user within cards can be assumed to detect that they are in the bus file and then Ora a quick file change).
    A check can be made in certain embodiments, based for example on an identification of the driver with a driving license, if he is criminally charged; alternatively if the vehicle is 100 years wanted. Lifestyle criminals are often less concerned about a thoughtful and thoughtful cross-style.
    Even in certain embodiments, the driver himself can inject into the device 200 that the vehicle 100 has an increased need for attention. This can be done, for example, in an emergency situation where the driver needs to drive a sick or needy person to hospital or the equivalent, for example when a highly pregnant woman needs to be rushed to a maternity ward. The driver can also choose to activate the sending of a warning message based on self-insight about their own momentary or existing limitations in chorus form, for example as a result of fatigue, stress, sudden onset of illness or other reason. Furthermore, a co-passenger in the vehicle 100 may admit that the vehicle 100 has an increased need for attention in the device 200. This is because the co-passenger can often complain about the driver's deficient chords and more objectively than the driver himself, while the co-passenger has an obvious self-preservation interest not to .
    In some cases, the detector 210 may include a sound level detector and / or a whistle detector, through which a grumpy fellow passenger and / or dissatisfied / crashing children may be detected in the vehicle 100. Highly dissatisfied / cranky fellow passengers and / or so-called rear seat drivers may be suspected of having a stress bike effect on the driver, which can lead to increased need for attention.
    In some embodiments, the detector 210 may be arranged to relieve the driver's stress level by feeding one or more stress-related body parameters such as moisture on the driver's skin, electrical resistance on the driver's skin, frequency of disturbances, body temperature, heart rate, respiration, blood pressure, muscle movements, hand sweats and the like. In this way, a stressed driver can be detected, regardless of the cause of this stress, by a comparison with one or more spruce guards.
    Furthermore, according to certain forms of performance, fellow road users may have disturbed the driver of the vehicle and have an increased need for attention as a result of, for example, the driver's driving. The driver of the vehicle may have previously received and stored judgments of his crossover style, and since a number of critical judgments, in excess of a configurable spruce value, are received, according to one embodiment, the driver of the vehicle is judged to have a heightened need for attention. This configurable spruce value can be, for example, 1, 2, 5, 10, 50 or a water in between or in the vicinity; or a multiple of some or some of these waters.
    Furthermore, the driver of the vehicle may have been blacklisted by fellow road user 110 at a previously wobbly meeting. The fellow road user 110 may have indicated that a permanent yarning, blacklisting, for the driver of the vehicle 100 is desired. Figure 3A shows an example of a vehicle interior of the fellow road user 110, which is located behind the vehicle 100, for example in the previously depicted scenarios in Figure 1A and Figure 1B. In this example, the fellow road user 110 may be a car, truck, bus or the like. The fellow road user 110 has access to a device 300, in order to be alerted to a surrounding vehicle 100 which has an increased need for attention. The device 300 includes, or is connected to a receiver 310, arranged to receive a warning message from the vehicle 100 indicating an increased need for attention. The receiver 310 can receive wireless signals transmitted through any of the previously listed vehicle-to-vehicle communication technologies.
    Furthermore, the device 300 may comprise, or be connected to an indicator 320, arranged to point to the vehicle 100 which has an increased need for attention for the fellow road user 110. This indicator 320 is exemplified in Figure 3A as a monitor with a camera on the rear side which is directed towards the track and the vehicle in front 100. Such an example of danger for vehicle 100 as the indicator 320 / screen can also show ashes in Figure 3B. In this case, the vehicle 100 is marked on the screen and a text message warns the road user 110 that the vehicle 100 has been shaken. The indicator 320 may also, or alternatively, include a loudspeaker or the like and send out an audible or rust message which draws the attention of the fellow road user to the vehicle 100.
    Figure 4A shows an example of a device 300 with a included receiver 310 and connected indicator 320. The co-traffic 110 is in this example constituted by a pedestrian which stands at the edge of the carriage, is connected to a transition stall.
    The device 200 in the vehicle 100 has in this example made a detection and analysis of how the driver acts at the transition stables and made the assessment that the driver has a tendency not to leave lined up, for example by not stopping at three of the five last passed transition stables, where it has been justified to stay. By warning the fellow road user 110 of this, it is possible to avoid that he trusts that the vehicle 100 will be left lined up at the Transition Stable and thereby avoid becoming a packer. In the illustrated example, the passenger's device 300 is constituted by a mobile telephone or similar barbaric device, arranged to receive wireless signals from the vehicle device 12 200. The ash exposure can be done, for example, by playing a light rust message to attract the car user's attention to the vehicle 100. In one embodiment shown in Figure 4B, the indicator 320 may be a pair of glasses having a built-in transparent display on which a mark may be made which marks or warns the vehicle 100. For example, but not necessarily, this may be done by a technique sometimes referred to as augmented reality. , or Augmented Reality (AR).
    Augmented reality is a general term for a technology in which information from the user's physical environment, such as the environment including the vehicle 100, as seen by the fellow road user 110 through the glasses 320, is mixed with information from a software application; in this case a marking and yarning for the vehicle 100. An example of augmented reality may be, for example, to show the image from a mobile camera together with the name of an object visible in the image. Augmented reality can be seen on a monitor; via computer, mobile phone, TV (game console), via a projection on another image surface such as the windscreen of a vehicle, a head up display, or the like in various embodiments.
    Figure shows an example of an embodiment where a vehicle 100 passes a fellow road user 110. The fellow road user 110 may have been given an opportunity to test the driving skills of the driver in the vehicle 100, through a questionnaire presented on the fellow road user's device 200, for example the fellow road user's mobile phone or other similar device . In the illustrated example, a rating of the driver can be made on three levels. This is an arbitrary example only; such assessment may include any number of levels according to various embodiments, including the ability to blacklist only one vehicle 100.
    An advantage of this embodiment is, in addition to warning other fellow road users of a potentially dangerous driver in a vehicle 100 and thereby reducing the risk of accidents, that it can stimulate many drivers to a sensible cornering to obtain a high straightening. This behavior of the drivers can be further strengthened, for example through a social community, sometimes called a "community" or similar where high rejection gives high status. In certain embodiments, the driver's claim may also be posted on an Internet site, or the like.
    Figure 6 shows an example of an embodiment from the perspective of a fellow road user. On the road in front of the fellow road user 110, you can see the current traffic through the windscreen of his vehicle; among other things, you see the vehicle 100, which in this example is marked with a star and an arrow marking to attract the attention of the fellow road user. 13 Other vehicles in front are marked in this example with a circle to show that they are equipped with a device 200, but that no reason for increased need for attention of this driver has been detected, or a triangle, respectively, which shows that this vehicle either lacks a working device 200 , or do not want to announce their status.
    These markings can be made, for example, by the technology augmented reality shown on a head-up display against the windscreen, projected against the windscreen or by including a transparent screen in different embodiments. In this scenario, an example is shown of how the fellow road user 110 can use the information obtained from a plurality of surrounding vehicles to directly identify the vehicle 100 which he primarily needs to look out for.
    Figure 7 illustrates an example of an embodiment of the invention. The flow chart in Figure 7 ashes a vehicle 700 in a vehicle 100, to determine and notify a fellow road user 110 that the vehicle 100 has an increased need for attention.
    According to certain embodiments, the vehicle 100 may be found to have an increased need for attention, for example when: the driver is training; the driver has a driving license that has been issued a short time ago than a second spruce guard; the driver is older than a third spruce value, such as 75 years; the driver has previously had his driver card revoked; The driver has a number of injury-free years, according to the driver's insurance company, which is less than a fourth spruce value; the vehicle 100 is an emergency vehicle during emergency; the vehicle's industry is about to run out; the vehicle 100 is in the bus lane without being a bus / taxi; the vehicle 100 constitutes a mail van, garbage truck or refuse collection vehicle such as e.g. salt truck / plow truck; the driver himself, or a fellow passenger, initiates the transmission of the warning message to the fellow passenger 110; and / or the driver or vehicle 100 has previously been judged to have an increased need for attention by fellow road users 110, or by other road users.
    In order to be able to correctly determine this increased need for attention and communicate this to the fellow road user 110, the method 700 may comprise a number of steps 701-704. It should be noted, however, that some of the steps described are included only in certain alternative embodiments of the invention, such as, for example, step 704. Furthermore, the described steps 701-704 may be performed in a slightly different chronological order from what the number order suggests and that some of they can be performed in parallel with each other. Method 700 includes the following steps: Step 701 Detecting a number of safety-critical operations in the vehicle 100 over a period of time.
    This time period can be predetermined or configurable. For example, the time period can be an hour, a day, a 5r, a lifetime or any other time period in between. The time period may in some embodiments be different for different types of security-critical operations.
    The safety-critical operation of the vehicle 100 may be caused by its driver and include, for example: lane change without the use of direction indicators; lane change without the driver looking in the rearview mirror; d5 the driver has the eyes closed longer than a predetermined period of time; as the driver is in a different lane than the vehicle's (GPS) navigator indicates; recirculation of another vehicle on the inside; d5 the distance in time to the vehicle in front is less than three seconds; d5 the driver activates his mobile phone without using hands-free while driving; as the vehicle's tachograph indicates that the permitted maximum short time without a break / day rest is p5 vague to be exceeded / has been exceeded; d5 speed limit is exceeded; when a fatigue warning post in the vehicle 100 indicates that the driver is fatigued; when an alcohol feeder in the vehicle 100 indicates that the driver has drunk alcohol or other similar act. Furthermore, the safety-critical operation in the vehicle 100 may comprise, for example, stopping the vehicle 100 p5 motorway, reversing the vehicle 100 p5 motorway, the vehicle 100 must swing left turn p5 country road.
    Step 702 The detected 701 number of security-critical operations is compared with one or more spruce values.
    In some embodiments, for example, the safety-critical operation may be to make a lane change without using direction indicators and the period may be, for example, one hour. The spruce value can be set to a predetermined or configurable integer between zero and impermeability, such as tie.
    Furthermore, several checkpoints can be configured in certain embodiments for the same security-critical operation, so that, for example, when the number of security-critical operations is less than a first checkpoint, the vehicle 100 is considered as without increased need for attention; since the number of safety-critical operations exceeds one first spruce value but not another, higher spruce value, the vehicle 100 is found to have an increased need for attention; and since the number of safety-critical operations exceeds both the first branch guard and the second branch guard, the vehicle 100 is found to have a significantly increased need for attention; etc.
    Such a spruce sword or spruce sword can in certain embodiments be different for different types of security-critical operations. For certain types of security-critical operations, the spruce value can be zero.
    Step 703 A message is sent to the fellow road user 110 to indicate an increased need for attention, as the detected 701 number of safety-critical operations exceeds the said one or more spruce values.
    The sent message may contain information addressed to the fellow road user 110 which indicates that the vehicle 100 does not have an increased need for attention, as the detected 701 number of safety-critical operations does not exceed the said one or more spruce values.
    The message can be transmitted over a wireless interface through vehicle-to-vehicle communication, such as WLAN, wi-fi, bluetooth or similar technology based on radio communication. In this way, the fellow road user 110 can be warned, or made aware of the vehicle's increased need for attention and take appropriate action with this in mind, such as keeping an extra long distance.
    Step 704 This process step may not be possible in some, but not necessarily all, embodiments of the procedure 700.
    An assessment of the vehicle's attention needs can in certain embodiments be received from the fellow road user 110, over a wireless interface. Such an assessment may include, for example, a rating, a rating, an estimate or a blacklist.
    Such an assessment can be received over a wireless interface through vehicle-to-vehicle communication, such as WLAN, wi-fi, bluetooth or similar technology based on radio communication.
    In this way, fellow road users can leave feedback to a driver and / or the behavior of a certain vehicle in traffic, and thereby also indirectly warn other fellow road users of this vehicle 100, without having to confront this driver and through, for example, gestures convey their assessment of this -Ware's cross-skill. ; an action that in itself can constitute a traffic hazard as the focus is taken from the traffic situation.
