    Title Method in connection with traffic monitoring, and a traffic monitoring system Field of the invention The present invention relates to a method and a system according to the preambles of the independent patent claims.
    Background of the invention Stagnant traffic is today not only a problem for the individual but also a societal problem that contributes to large costs and serious environmental consequences, and it is therefore increasingly important to be able to review the current traffic situation as soon as possible. Today, the traffic situation is monitored in some cases by cameras mounted along specially trafficked roads, but the monitoring is usually based on an individual vehicle driver reporting any disturbances to a traffic center.
    From 2014, there will be a requirement for trucks to be equipped with an automatic emergency braking system. A prerequisite for such a system to work is that the vehicle is equipped with a number of sensors to detect movements and objects in the environment.
    The sensors include, among other things, radar sensors which are particularly advantageous when detecting movements in the direction of movement of the vehicle. Furthermore, the vehicles are often equipped with cameras which, among other things, are used to detect objects next to the vehicle, and are used, for example, in connection with coral guard systems, LKA system (Lane Keeping Assistance). Distance sensors and cameras are already used today, for example in adaptive cruise control systems, ACC (Adaptive Cruise Control) systems.
    The forthcoming legal requirement has led to a major technological development in distance sensors and advanced image processing. This has been further developed through so-called sensor fusion, which points to opportunities for future object identification in real-time systems. At the same time, research in GPS and map data management has a maturity level that strengthens the precision in food data and contributes with additional significant information.
    Among other things, this makes it possible to provide systems which, for example, can detect which speed limit the road holds. Future systems will probably be able to offer additional information from the infrastructure (vehicle-toinfrastructure, V2I). Information Than traffic lights, other types of road signs, etc. can create additional parameters that together can help increase traffic safety.
    Together with information than GPS, map data, distance sensors, camera surveillance, and wireless vehicle-to-vehicle (V2V) communication, information from the infrastructure will form the basis for a high-quality electronic horizon, which in turn also can contribute to an Okad traffic safety.
    U.S. Pat. No. 5,598,163 discloses a method for detecting solid or moving objects in the vicinity of a vehicle using radar technology. The method is used, among other things, in an anti-collision system.
    The object of the present invention is to achieve an improved traffic monitoring where, among other things, an earlier indication of possible traffic obstructions is obtained.
    SUMMARY OF THE INVENTION The above objects are achieved by the invention defined by the independent claims.
    Preferred embodiments are defined by the dependent claims.
    The invention is based on the inventors' insight into the consequences of the vehicles 30 being "forced" to be equipped with the type of sensors discussed above, as there will be necessary information available to achieve a global presentation of the traffic team in real time.
    The basic idea behind the invention can simply be described as the sensors, for example radars and cameras, which are arranged on each vehicle being used to obtain an indication of how the traffic situation in the vehicle's environment is - it can be simply said that the vehicle is used as a night probe. If several vehicles are used in this way and the information received while the vehicles are compiled, a global compilation of the traffic situation can be achieved.
    According to two exemplary aspects of the invention, the driver is simply asked to report the passability or traffic situation of the road.
    According to one aspect of the present invention, for example, radar is used to detect stationary obstacles on the road ahead of the vehicle. When an obstacle has been detected, the driver can choose to report the obstacle, information about time, place and type of obstacle is then sent to affected parties, for example traffic monitoring or transport planning.
    According to another aspect of the present invention, radar is used to detect the speed of oncoming traffic. If the speed is less than the speed limit of the vehicle by a certain number of km / h, -Waren is asked to report the traffic situation. The driver can then choose to report the traffic situation, and information about time and place is then sent to the relevant pools, such as traffic monitoring or transport planning.
    The advantage of the solution according to the invention is that it uses existing infrastructure and thus contributes to increased accessibility and increased traffic safety.
    For example, the information can be sent automatically from the vehicle, or can be sent after it has been verified by the driver, ie. the system in the vehicle assembles and the driver gives his consent for the information to be sent in agag.
    BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a flow chart illustrating the method of the present invention.
    Figure 2 shows a flow chart illustrating an embodiment of the method of the present invention.
    Figure 3 is a schematic block diagram illustrating the traffic monitoring system of the present invention.
    Detailed Description of Preferred Embodiments of the Invention Referring to the figures, preferred embodiments of the invention will now be described in detail.
    Figure 1 shows a flow chart illustrating the method of the present invention.
    The invention relates to a method for monitoring a traffic situation, comprising: sensing, with the aid of one or more sensors on a first vehicle, the condition, conditions or circumstances of the vehicle and the environment around the vehicle and determining status parameters depending thereon, where the status parameters include at least the vehicle's speed, position and current time, and at least one parameter related to the environment around the vehicle, generates a vehicle environment signal in dependence on said status parameters, i.e. the status parameters are formatted so that the latter can be easily identified, sending said vehicle environment signal to a central unit.
    According to one embodiment, the driver of the vehicle is requested to verify the information in the vehicle environment signal, and that the vehicle environment signal is sent to the central unit only if the driver has verified the information. This embodiment is damaged by the flow chart in Figure 2.
    Alternatively, the vehicle environment signal can be sent automatically as soon as it is available after step B) has been completed.
    For both alternatives, the signal is sent via wireless, for example via the mobile network or via an Internet connection.
    The parameter related to the environment refers to the speed of other vehicles near the first vehicle or the identification of obstacles along the vague of the first vehicle, and that the method includes comparing the speed of the own vehicle with the current speed limit and generating a first deviation signal depending on the comparison .
    The method comprises, according to another embodiment, further determining the speed of oncoming vehicles and comparing the determined speed with the current speed limit and generating a second deviation signal depending on the comparison.
    Step C), i.e. to send the vehicle environment signal, is performed only if a deviation signal or both deviation signals indicate a deviation that exceeds a predetermined threshold level.
    The central unit is, according to one embodiment, adapted to compile the information from vehicle environment signals received from a plurality of vehicles within a geographically limited area and generate a traffic situation signal for the area depending on the received vehicle environment signals. Darigenonn provides up-to-date and up-to-date information on the traffic situation in the area where the vehicles are located as sent in the information.
    With reference to the block diagram in Figure 3, the traffic monitoring system according to the present invention will now be described.
    The invention thus also comprises a traffic monitoring system 2 intended to monitor a traffic situation, and comprising a central unit 4 comprising a communication unit 6. The central unit may for example be located at a traffic monitoring center and may consist of a personal computer adapted for use in connection with traffic monitoring. For example, presentation screens and relevant map databases may be available.
    The traffic monitoring system further comprises at least one vehicle sensor module 8 arranged on a first vehicle 10 and adapted to receive sensor signals 12 Than one or more sensors 14 on the vehicle adapted to detect the condition, conditions or circumstances of the vehicle and the environment around the vehicle. These sensors can, for example, consist of sensors for distance assessment, e.g. radar, sensors for object identification, e.g. camera and for position and speed wetting, e.g. GPS sensors.
    The vehicle sensor module 8 is adapted to determine status parameters depending on the measured values, where the status parameters include at least the vehicle's speed, position and current time, and at least one parameter related to the environment around the vehicle. The vehicle sensor module is further adapted to generate a vehicle environment signal 16 in dependence on said status parameters, and to send the vehicle environment signal to the central unit 4 where the communication unit 6 receives the signal.
    According to a preferred embodiment of the invention, the vehicle environment signal is adapted to be presented to the driver of the vehicle who is asked to verify the information in the vehicle environment signal. The information can, for example, be presented on a display in the instrument panel. If the driver intends to verify the information, this can be done by consuming a command, for example via controls in the instrument panel. When the information has been verified, the vehicle environment signal is sent wirelessly to the communication unit in the central unit.
    The transmission can, for example, take place via the mobile network or via an Internet connection.
    According to another embodiment, the vehicle environment signal is instead sent automatically to the central unit as soon as it is generated.
    The parameter related to the environment refers, according to one embodiment, to the speed of other vehicles in the vicinity of the first vehicle or the identification of obstacles along the vagus of the first vehicle. When feeding the speed of other vehicles, radar sensors are preferably used, while when identifying obstacles along the road, camera sensors can also be used.
    According to a further embodiment, the vehicle sensor module is adapted to compare the speed of the own vehicle with the current speed limit and generate a first deviation signal depending on the comparison. Bile velocity limitation can, for example, be phased from a map database stored in the vehicle sensor module. The deviation signal is thus generated if the own speed deviates too much from the speed limitation, which can for instance be caused by cow formation which makes the speed significantly lower. For example, if the speed limit is 90 km / h, a threshold level can be set to 45 km / h, ie. the deviation signal is generated if the own speed is lower than 50% of the crazy speed limit.
    Similarly, the speed of intrusive vehicles can be determined and compared with the current speed limit and the vehicle sensor module is adapted to generate a second deviation signal depending on the comparison. If the speed of the oncoming vehicle deviates too much from the galloping speed limit, it may be an indication that some obstacle has caused cow formation. Even in this case, the deviation signal can be generated if the speed of the oncoming traffic is lower than, for example, 50% of the galling speed limit.
    According to one embodiment, the vehicle sensor module is adapted to transmit the vehicle environment signal only if one or more of the deviation signals indicate a deviation that exceeds a predetermined threshold level.
    The central unit is adapted to compile the information from vehicle environment signals received from a plurality of vehicles within a geographically limited area and generate a traffic situation signal for the area depending on the vehicle environment signals received. If several vehicles within an area submit information about the traffic situation that is consistent, using the present invention, a current, and constantly updated presentation of the traffic situation can be obtained. It can, for example, be presented on monitors at the traffic center, but can of course also be made accessible via a website.
    The present invention is not limited to the preferred embodiments described above. Different alternatives, modifications and equivalents can be used. The above embodiments are, therefore, not to be construed as limiting the scope of the invention as defined by the appended claims.
