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 hereinafter referred to in each case as a receiver vehicle, since it is the respective receiver of the information about the wrong-way driver vehicle.
  • the at least one receiver vehicle is informed by a stationary server device about the wrong-way driver vehicle.
  • the invention also includes the server device and a motor vehicle, which can communicate with the server device as a receiver vehicle, as well as a motor vehicle, which independently detects a wrong-way or ghost ride.
  • warning messages such as from wrong-way drivers
  • TMC Traffic Message Channel
  • these messages are not sent specifically to the relevant region, but globally, at least according to the transmitter range. This means that the message has no relation to the current whereabouts of a receiver vehicle or its route.
  • the messages are only relevant to receiver vehicles in the vicinity of the traffic event and only when the receiver vehicle is approaching the traffic event.
  • messages about wrong-way drivers must also be forwarded to a recipient vehicle with a short time delay in order to achieve the maximum benefit.
  • a motor vehicle which recognizes automatically, 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 is known, which selectively sends a warning about a wrong-way driver only to those motor vehicles whose current position and route has a relation to the position of the wrong-way driver vehicle. It poses a problem how to identify such recipient vehicles.
  • the object of the invention is to inform a respective driver of at least one receiver vehicle specifically about a wrong-way driver vehicle, which is relevant for his route, and / or to protect him otherwise.
  • the invention provides a method by means of which at least one receiver vehicle is informed about a wrong-way driver vehicle.
  • a stationary server device receives from the wrong-hander vehicle or from another motor vehicle or from a permanently installed monitoring device wrong-way driver data which describe at least one position of the wrong-way driver vehicle.
  • the wrong-way driver data may also indicate, for example, a current direction of travel and / or a planned and / or estimated route and / or a driving speed and / or a currently traveled lane or lane.
  • the server device provides a digital road map that is divided into subareas of predetermined size.
  • a tile may be used whose edge length may be in a range of 0.01 degrees to 0.1 degrees.
  • the degree refers to the longitude and the latitude.
  • Such a subarea constitutes a segment of the road map and comprises or describes a subarea in which a motor vehicle can be located.
  • the server device uses the wrong-way driver data to select the sub-area in which the wrong-way vehicle is located.
  • the map data of the selected sub-area is then updated by means of the wrong-way driver data.
  • map data available for the subarea which also contain an entry or a description of the wrong-way driver 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 receiver vehicle. For this purpose, the at least one receiver vehicle checks on the on-board road map whether the wrong-way driver vehicle for the receiver vehicle fulfills a predetermined criterion of relevance. If the relevance criterion is met, at least one predetermined protective measure is carried out in the receiver vehicle. The receiver vehicle thus receives the map data, but does not immediately perform the at least one protective measure. Rather, it is first checked on the basis of the on-board road map, whether the wrong-way driver vehicle is relevant at all for the receiver vehicle.
  • the road map By using the road map, it is also possible to match a route planned or estimated by the receiver vehicle with the position of the wrong-way driver vehicle or its wrong-way driver data. In this case, it is not necessary to transmit the complete road map from the server device to the receiver vehicle, but by dividing the road map into subareas and generating updated map data for only a subarea, only the partial area of the road map required for displaying the wrong-way vehicle is shown the wrong-way vehicle to enter or update the recipient vehicle in its on-board road map. If the wrong-way driver data also indicates the route of the wrong-way vehicle, it is also possible to check whether the route of travel 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 receiver vehicle to determine for itself using the on-board road map or to determine whether the wrong-way driver vehicle is relevant, ie fulfills the relevance criterion, and then only if the relevance criterion is met at least one predetermined safety measure is performed in the respective receiver vehicle.
  • a driver of the recipient vehicle is affected by the at least one predetermined protective measure only if the wrong driver vehicle is actually relevant or dangerous.
  • a wrong-way driver vehicle is to be understood in particular as meaning a motor vehicle which moves on a road which has two structurally separate road sides, each with a predetermined uniform direction of travel, counter to the prescribed direction of travel of the road side on which it is traveling.
  • the invention also includes developments, the characteristics of which provide additional advantages. Since each receiver vehicle decides for itself whether the wrong-way driver vehicle is relevant, it can be provided that the server device transmits the map data to a plurality of receiver vehicles, irrespective of their respective current own position and / or route. The server device thus transmits the map data as a broadcast signal. The relevance is then individually checked by means of the relevance criterion exclusively in the recipient vehicles. Alternatively, the at least one receiver vehicle may register to receive certain subareas. For this purpose, it can be provided that the server device receives registration data from each of the receiver vehicles, by which the respective receiver vehicle registers for at least one respective subarea.
  • the server device it is thus known via which at least one subarea the respective receiver vehicle wishes to be informed, since the receiver vehicle has registered for the respective subarea.
  • the server apparatus transmits the updated map data only to the at least one receiver vehicle of the plurality of receiver vehicles, which is registered for the subarea in which the wrong driver vehicle is located and / or to which the wrong vehicle driver is approaching.
  • a receiver vehicle can thus register, for example, the subarea in which it is currently located and / or at least one adjacent subarea in each case at the server device by means of registration data. Then, the receiver vehicle is supplied with map data only if the wrong-way vehicle is in a registered sub-area and / or drives the wrong-way vehicle thereon.
  • 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 server device side.
  • the relevance criterion used for this purpose preferably comprises that a planned or estimated route of the recipient vehicle intersects a route of the wrong-way driver vehicle.
  • a planned route can be read out or received from a respective navigation device.
  • An estimated travel 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 may include that the wrong-way driver vehicle must be arranged in front of it in the direction of travel of the receiver vehicle. If the wrong-way driver vehicle is already behind it in the direction of travel of the receiver vehicle, then the wrong-way driver vehicle can no longer be dangerous to the receiver vehicle and is therefore irrelevant. Additionally or alternatively, the relevance criterion may include that the wrong-vehicle driving-route data indicate the same road as the traveling-route data of the receiving vehicle. By considering the route is in the event that the wrong-way driver on a highway and the receiver vehicle on a parallel running country road in different directions are traveling, the relevance criterion is not met.
  • the relevance criterion preferably includes that the wrong-way vehicle drive on the same road side as the receiver vehicle.
  • road side is meant in structurally separate lanes each half of the road on which a uniform direction is prescribed.
  • the at least one protective measure must be carried out.
  • the at least one protective measure includes preferred that an indication of the wrong-way vehicle in the receiver vehicle is issued. As a result, a driver or vehicle occupant of the recipient vehicle is warned.
  • the at least one protective measure preferably comprises activating an autopilot device for performing a semi-automatic or fully automatic ride in the receiver vehicle and programming or setting the autopilot device for an evasive maneuver for avoiding the wrong-way vehicle.
  • Fully automatic driving provides for performing the longitudinal guidance (acceleration and deceleration) and transverse guidance (steering) of the receiver vehicle through the autopilot device.
  • a semi-automatic driving mode provides only the longitudinal guide or the transverse guide.
  • a partially automatic driving operation may be limited to an emergency stop, for example.

Abstract

L'invention concerne un procédé permettant d'informer au moins un véhicule récepteur (16) au sujet d'un véhicule roulant à contresens (15), selon lequel un dispositif serveur fixe (19) reçoit du véhicule roulant à contresens (15) des données de circulation à contresens (20) qui décrivent sa position instantanée. Selon l'invention, le dispositif serveur (19) produit une carte routière numérique (23) qui est divisée en aires partielles (24) d'une dimension prédéfinie, sélectionne sur la carte routière (23) au moyen des données de circulation à contresens (20) l'aire partielle (24) dans laquelle le véhicule roulant à contresens (15) se trouve, met à jour au moyen des données de circulation à contresens (20) les données cartographiques (27) de l'aire partielle sélectionnée (24), et adresse les données cartographiques mises à jour (27) au/aux véhicules récepteurs (16). Le ou les véhicules récepteurs (16) entrent les données cartographiques reçues (27) dans une carte routière numérique embarquée (25) et vérifient au moyen de la carte routière numérique embarquée (25) si le véhicule roulant à contresens (15) remplit pour le véhicule récepteur (16) un critère de référence prédéfini (28), et une mesure de protection (29) est mise en œuvre dans le véhicule récepteur (16) si le critère de référence (28) est rempli.
