Definitions

  • the invention relates to a method for informing at least one motor vehicle about a wrong-way driver vehicle.
  • the at least one motor vehicle is referred to below as the recipient vehicle, since it is the respective recipient of the information about the wrong-way driver vehicle.
  • the at least one receiver vehicle is informed about the wrong-way driver vehicle by a stationary server device.
  • the invention also includes a motor vehicle that communicates with a server device as a receiver vehicle.
  • warning messages such as for example against wrong-way drivers
  • TMC Traffic Message Channel
  • These messages are also not broadcast specifically for the relevant region, but globally, at least according to the range of the broadcaster. This means that the message has no relation to the current location of a recipient vehicle or its route.
  • the messages are only relevant for recipient vehicles in the vicinity of the traffic event and only if the recipient vehicle is moving towards the traffic event.
  • reports of wrong-way drivers have to be forwarded to a recipient vehicle with a slight time delay in order to achieve the maximum benefit.
  • a motor vehicle that automatically detects if it is on a wrong way or ghost ride. The motor vehicle can then report current location coordinates and the direction of travel to a central location.
  • a server device which specifically sends a warning about a wrong-way driver to those motor vehicles whose current position and route are related to the position of the wrong-way driver vehicle. It is a problem how to identify such recipient vehicles.
  • the invention is based on the object of specifically informing a respective driver of at least one receiver vehicle about a wrong-way driver vehicle which is relevant to his route and / or otherwise protecting him from it.
  • the invention provides a method by means of which at least one recipient vehicle is informed about a wrong-way driver vehicle.
  • a stationary server device receives wrong-way driver data from the wrong-way driver vehicle or from another motor vehicle or from a permanently installed monitoring device, which describe at least one position of the wrong-way driver vehicle.
  • the wrong-way driver data can, for example, also indicate a current driving direction and / or a planned and / or estimated driving route and / or a driving speed and / or a currently used lane or lane (English lane or track).
  • the server device can adequately trigger a protective measure in the at least one receiver vehicle on the basis of the wrong-way driver data.
  • the server device provides a digital road map which is divided into subareas of predetermined size. For example, a tile can be used as each partial area, the edge length of which can be in a range from 0.01 degrees to 0.1 degrees. The degree refers to the longitude and latitude.
  • a partial area represents a segment of the road map and includes or describes a partial area in which a motor vehicle can be located.
  • the server device uses the wrong-way driver data to select the partial area in which the wrong-way driver vehicle is located.
  • the map data of the selected partial area are then updated using the wrong-way driver data. So there is now map data available for the partial area also contain an entry or description of the wrong-way driver vehicle.
  • These updated map data of the partial area are sent to the at least one recipient vehicle.
  • the at least one receiver vehicle enters the received map data into an on-board digital road map. Now it has to be decided whether a protective measure is necessary for the respective driver of the at least one recipient vehicle. For this purpose, the at least one recipient vehicle checks on the on-board road map whether the wrong-way driver vehicle fulfills a predetermined relevance criterion for the recipient vehicle. If the relevance criterion is met, at least one predetermined protective measure is carried out in the recipient vehicle. The recipient vehicle therefore receives the card data, but does not immediately implement the at least one protective measure. Rather, the on-board road map is first used to check whether the wrong-way driver vehicle is relevant to the recipient vehicle at all.
  • the road map By using the road map, it is also possible to compare a route planned or estimated by the recipient vehicle with the position of the wrong-way driver vehicle or its wrong-way driver data. It is not necessary to transmit the complete road map from the server device to the recipient vehicle, but by dividing the road map into partial areas and generating updated map data for only one partial area, only the partial area of the road map required for displaying the wrong-way driver vehicle, i.e. the partial area with the wrong-way driver vehicle to enter or update the recipient vehicle in its on-board road map. If the wrong-way driver data also indicate the route of the wrong-way driver vehicle, it can also be checked whether the route of the recipient vehicle and the route of the wrong-way driver vehicle are likely to intersect.
  • the advantage of the invention is that the server device, by providing the map data, enables each recipient vehicle to determine for itself on the basis of the on-board road map or to determine whether the wrong-way driver vehicle is relevant, i.e. fulfills the relevance criterion, and then only if the relevance criterion is met at least one predetermined security measure is carried out in the respective recipient vehicle. A driver of the recipient vehicle is only affected by the at least one predetermined protective measure if the wrong-way driver vehicle is actually relevant or dangerous.
  • a wrong-way driver vehicle is to be understood in particular as a motor vehicle which moves on a road which has two structurally separate road sides, each with a predetermined uniform driving direction, against the prescribed driving direction of the road side on which it is traveling.
  • the invention also includes further developments, the features of which result in additional advantages.
  • the server device sends the card data to a large number of recipient vehicles independently of their respective current own position and / or route.
  • the server device thus sends out the card data as a broadcast signal.
  • the relevance is then checked individually in the recipient vehicles using the relevance criterion.
  • the at least one receiver vehicle can register for the reception of certain subareas.
  • the server device receives registration data from each of the receiver vehicles, by means of which the respective receiver vehicle registers for at least one respective partial area. It is thus known in the server device about which at least one partial area the respective recipient vehicle would like to be informed, since the recipient vehicle has registered for the respective partial area.
  • the server device sends the updated map data only to the at least one recipient vehicle from the plurality of recipient vehicles which is registered for the partial area in which the wrong-way driver vehicle is located and / or to which the wrong-way driver vehicle is approaching.
  • a recipient vehicle can thus, for example, register the partial area in which it is currently located and / or at least an adjacent partial area with the server device by means of registration data. Then the recipient vehicle is supplied with map data only if the wrong-way driver vehicle is in a registered partial area and / or the wrong-way driver vehicle drives towards it. Through this registration, a targeted preselection of the at least one receiver vehicle for the transmission or transmission of the updated map data is thus already carried out on the part of the server device.
  • the relevance criterion used for this preferably includes that a planned or estimated travel route of the recipient vehicle intersects a travel route of the wrong-way driver vehicle.
  • a planned route can be read out or received from a respective navigation device.
  • An estimated route can be determined, for example, on the basis of historical driving data of the respective recipient vehicle and / or a statistical description of a possible route of the respective recipient vehicle.
  • the relevance criterion can include that the wrong-way driver vehicle must be arranged in front of the recipient vehicle in the direction of travel.
  • the relevance criterion can include that route data of the wrong-way driver vehicle indicate the same road as route data of the receiver vehicle. The consideration of the route does not meet the relevance criterion in the event that the wrong-way driver is traveling on a motorway and the recipient vehicle is traveling in a different direction on a country road running parallel to it. In the event that the recipient vehicle and the wrong-way driver vehicle are traveling on the same road, the relevance criterion preferably includes that the wrong-way driver vehicle is traveling on the same side of the road as the recipient vehicle. In the case of structurally separate lanes, the side of the street means half of the street on which a uniform direction of travel is prescribed.
  • the at least one protective measure is only carried out if the wrong-way driver vehicle is traveling on the same road in relation to the recipient vehicle and is still in front of the recipient vehicle and it can be assumed that the routes of the two vehicles intersect or intersect.
  • the at least one protective measure must be carried out. Which includes at least one protective measure preferably that an indication of the wrong-way driver vehicle is output in the recipient vehicle. A driver or vehicle occupant of the recipient vehicle is hereby warned. Additionally or alternatively, the at least one protective measure preferably includes that an autopilot device for carrying out a partially automatic or fully automatic trip in the recipient vehicle is activated and the autopilot device is programmed or set for an evasive maneuver to evade the wrong-way driver vehicle.
  • Fully automatic driving mode provides for the longitudinal guidance (acceleration and braking) and lateral guidance (steering) of the recipient vehicle to be carried out by the autopilot device.
  • a semi-automatic driving mode only provides for longitudinal guidance or transverse guidance. For example, semi-automatic driving can be limited to an emergency stop. By activating the autopilot device, the recipient vehicle can react faster than a driver of the recipient vehicle could.
  • the server device can also send out at least one control signal by means of which the server device switches at least one variable message sign and / or an electronic sign bridge.
  • a variable message sign can be constructed, for example, on the basis of light-emitting diodes, the activation of which allows a pixel-by-pixel representation of information about the wrong-way driver vehicle to be displayed, for example on the roadside.
  • An electronic sign bridge can span the street and, based on light-emitting diodes or other light sources, for example, display a pixel-by-pixel representation of the information.
  • a monitoring device detects the wrong way or ghost trip in the wrong-way driver vehicle by recognizing a currently used road class with directional separation based on a current position and a digital road map.
  • a road class can be, for example, a motorway or an expressway.
  • the monitoring device can detect oncoming traffic (oncoming motor vehicles) and / or at least an information sign be recognized.

  • a vehicle camera can also be used as a plausibility check. If an object detection connected downstream of the vehicle camera detects that a "prohibited passage sign" is being driven through, the vehicle can be declared as a wrong-way driver.

  • Communication in vehicles of other road users can be configured as follows.
  • the vehicles move on a navigation map, i.e. an on-board digital road map.
  • This street map can be organized or divided into subareas, for example in the form of "tiles" with a fixed size (for example a size of 0.05 x 0.05 degrees).

Vehicles know their current tile including their neighboring tiles and use registration data to register in the backend system for this subset of preferred tiles. This enables the backend system to send tiles with updated map data more efficiently and specifically only to those vehicles that can derive specific benefits from the information. The relevant vehicles are thus notified of an update by the backend system.
  • the relevance of the information is assessed locally in the vehicle, i.e. a determination of the road users for whom the wrong-way driver report is relevant.

  • the route of the recipient vehicle must also be included. For example, a wrong-way driver on the highway and a receiver vehicle on a country road could be traveling in different directions. If at the same time the distance between these two roads is smaller than the variance of the GPS / GNSS position determined, a warning message would be incorrectly propagated become. An error message is counteracted by considering the route.
  • the route of the recipient vehicle can be taken from the set navigation destination or from an estimated route. The person skilled in the art can combine the corresponding conditions into one relevance criterion.
  • Warning notices and maneuver notices for wrong-way drivers can thus be generated for other road users in the recipient vehicles, and if relevant, acoustic, visual and haptic warnings can be given analogously to the point "Warning notices for wrong-way drivers and maneuver notices".

Details can e.g. the lane used by the wrong-way driver and its speed. This can better resolve or mitigate a dangerous situation. Thanks to the additional details, recommendations such as "Change to the left / right side” (i.e. "safe” lane for this situation). Some of these points can also be done automatically depending on the situation.
  • the vehicle will switch to a piloted mode in the future and automatically clarify the situation using an autopilot device.
  • the vehicle can also draw a "wrong-way driver icon" locally and dynamically on the navigation map shown on the display or screen at the location of the wrong-way driver. Other vehicles that are not in the relevant area and do not drive in the relevant direction of travel would not do this.
  • Previous methods are characterized by a considerable delay and distribute the warning geographically over a large area and not in a targeted manner to the relevant road users in the vicinity of the traffic event.
  • the method described here enables warnings to be displayed with current location-time reference and / or accuracy, and optionally additional details. Details can be, for example, the lane used by the wrong-way driver and / or its speed. Automatic detection of a wrong-way driver and immediate notification to other road users via a back-end system happens in real time. A time-consuming manual report by eyewitnesses and sending via TMC can be omitted.
  • warning message can also be passed on to emergency services or used to switch variable message signs and / or signals on electronic gantries.
  • an anonymized aggregation of traffic events over a longer period of time can determine whether wrong-way drivers have already been reported more frequently at specific points. This information can e.g. Municipalities and cities are made available so that measures can be taken to improve the labeling of the relevant driveways in the wrong direction.
