Definitions
- the invention relates to a method for location-dependent warning of vehicles from dangerous situations with the preamble features of claim 1.
- the DE utility model GM 91 08 827 shows a signal output device for controlling the brake light in a motor vehicle, in which the position of the actuated by the driver of the vehicle accelerator pedal is evaluated to determine a sudden decrease in the vehicle acceleration.
- a moderate release of the accelerator pedal occurring under normal conditions does not initiate activation of the brake lights, while in the case of an abrupt release of the accelerator pedal, as this directly precedes emergency braking, the brake lights are activated.
- the choice of the change of the accelerator pedal position, in which a brake light control takes place always a compromise between avoiding unnecessary control of the brake lights in the case where no emergency braking follows the accelerator pedal change, and the necessary control of the brake lights in the case, in an emergency braking follows the accelerator pedal change.
- the DE 19814574 discloses a method for generating a signal for driving the brake lights of a motor vehicle.
- the change over time of the accelerator pedal change quantity representing the position of an accelerator pedal which can be actuated by the driver of the vehicle is determined, and the ascertained Accelerator pedal change quantity compared with at least one predefinable threshold value, and generates the signal depending on the comparison, wherein the threshold value is determined depending on at least one of the current driving stability of the vehicle and / or present driving safety of the vehicle representing stability / safety variable.
- From the DE 4342856 is a circuit for a hazard warning system equipped with an antilock system motor vehicle known. When an anti-lock control operation is triggered, a hazard warning light is activated.
- the DE 10005867 discloses a warning system, which is equipped with electronic circuits and sensors, and detects the vehicle's own movement and also the rear traffic events and identified by comparison and evaluation of this information situations with potential dangers and outputs warning signals.
- the actuation of the warning is primarily used to warn that a vehicle is in a potential danger situation or is insoloher.
- the surrounding vehicles can only determine on the basis of the visual image that a possible danger situation can occur, but not whether this dangerous situation has relevance for the own vehicle.
- the US 2002/0105423 A discloses a method for location-dependent warning of vehicles against dangerous situations according to the features of the preamble of claim 1.
- the invention is therefore based on the object to enable a simple and rapid production of a situation-dependent exchange of information between at least two vehicles in order to reduce dangerous situations.
- the advantage of the invention lies in the simple and efficient implementation of an output of individualized warnings to as many road-engaging vehicles as possible in order to recognize potential danger spots and to minimize dangerous situations. Furthermore, the information content of the transmitted message, which is first perceived by the surrounding vehicles as a "conventional" warning, advantageously extends and evaluates, the linking of various signals resulting in added value. It is advantageous that the hitherto necessary carrying a warning sign in a vehicle is required by the inventive method less often and mitigated the risk in positioning and setting up a warning sign for a person or no longer occurs. This is particularly advantageous in high and fast roads with high risk of accidents.
- the establishment of a communication link for warning of potential danger spots is shown.
- a vehicle vehicle or a vehicle infrastructure communication transmits according to the invention a first vehicle that the hazard warning lights is turned on.
- the position of the vehicle is transmitted.
- a second vehicle receives this information via the above-mentioned communication, if the first vehicle is located at a relevant location for the second vehicle.
- This relevant location is determined, for example, by map data or navigation / route guidance and made plausible.
- a warning is issued far in front of a non-visible curve in the vehicle, if the information is a relevant one, which is checked on the basis of the transmitted location information of the sending vehicle, if the vehicle is in standstill, for example.
- a warning symbol appears on a playback unit such as a cockpit display or head-up display.
- Vehicle safety systems all braking systems available in the vehicle can be used with electronic control.
- Vehicle safety systems may include Electronic Break System (EBS), Engine Management System (EMS), Antilock Braking System (ABS), Traction Control (ASR), Electronic Stability Program (ESP), Electronic Differential Lock (EDS), Transmission Control Unit (TCU) Electronic Brake Force Distribution (EBV) and / or Engine Drag Torque Control (MSR).

- Driver assistance systems are electronic ancillary devices in vehicles to assist the driver in certain driving situations. Here are often safety aspects, but also the increase in ride comfort in the foreground.
- driver assistance systems are, for example, parking aid (sensor arrays for obstacle and distance detection), brake assist (BAS), cruise control, adaptive cruise control or proximity control (ACC), distance warning, turn assistant, traffic jam assistant, lane detection system, lane departure warning / lane assist (transverse guidance assistance, lane departure warning (LDW)), lane keeping support), lane change assistant, lane change support, Intelligent Speed Adaptation (ISA), adaptive cornering light, tire pressure monitoring system, driver condition detection, traffic sign recognition, platooning, convoy driver, Automatic emergency braking (ANB), headlamp dipping and dipping assist, night vision system.

- the visual and audible signals are supplemented by an intuitively detectable signal from the Force Feedback accelerator, which is output to the driver via a driver assistance system. By counter pressure it suggests the driver to slow down the pace.
- This triggering of the Force Feedback accelerator pedal is thus triggered by a defective and no longer roadworthy vehicle on the road, if additional information, such as meta-information from the sending vehicle are checked when activating the hazard warning lights, for which reason the hazard warning lights was turned on.
- a means of communication such as a telematic module using DSRC (Dedicated Short Range Communication) and / or Wireless Local Area Network (WLAN) transmission, provides a warning signal to the telematics units of other vehicles in the vicinity of sent several hundred meters. The drivers have sufficient time through this communication to slow down the pace and to drive carefully to the danger spot.
- DSRC Dedicated Short Range Communication
- WLAN Wireless Local Area Network
- additional information is added to the hazard warning function and, according to the invention, a situation analysis for the warning signal-emitting vehicle is carried out over a short period of time. Is found that the vehicle is stationary and no further meta-information is transmitted, thus all four wheels are detected as not being in motion over a period to be determined, this is interpreted as a parking situation, such as in the second row. If the vehicle continues to move slowly and the hazard warning function is still active, a potential jam end is detected by the received information.
- the sending vehicle has remained idle and thus "the vehicle can not move on suddenly", as is the case with second-row parking or when encountering a traffic jam end, it is made plausible that the sending vehicle is stationary and By itself, by using its own drive unit, can no longer be moved by technically determined additional information, eg is determined whether the warning triangle has been removed from its holder, the information of the fuel gauge, or the sensor is checked in the tank or if the hood is open. Furthermore, all information relating to the engine is transmitted via a data link such as e.g. read out the CAN bus. Alternatively, the diagnostic data output on a diagnostic connector is used to evaluate the vehicle condition. In addition to information representative of the operation of the powertrain, various technical means are used to verify that a tire is no longer fit for operation, such as when it "runs out of air".
- the information about the closed or opened access device to the vehicle is additionally monitored and used for plausibility checking.
- access devices are all entry options, such as doors, flaps, hoods and covers meant, which allow a person to get into the vehicle interior. It is checked, for example, whether a door or the trunk is open. For example, if a door is open and the hazard warning lights active, it is concluded that a There is a risk that people are on the road and the local area of the vehicle is classified by non-visible further danger objects, such as pedestrians on the road, with respect to the potential hazard potential higher.
- This additional information is also displayed to the driver of the second vehicle, if the information is classified as relevant by a separate situation analysis.

Die Betätigung der Warnlage dient primär zur Warnung, dass ein Fahrzeug in eine mögliche Gefahrensituation gerät oder sich insoloher befindet. Die umgebenden Fahrzeuge können nur aufgrund der visuellen Aufnahme feststellen, dass eine mögliche Gefahrensituation eintreten kann, jedoch nicht, ob diese Gefahrensituation eine Relevanz für das eigene Fahrzeug besitzt.The actuation of the warning is primarily used to warn that a vehicle is in a potential danger situation or is insoloher. The surrounding vehicles can only determine on the basis of the visual image that a possible danger situation can occur, but not whether this dangerous situation has relevance for the own vehicle.
Die
Der Erfindung liegt daher die Aufgabe zu Grunde, eine einfache und schnelle Herstellung von einem situationsabhängigen Informationsaustausch zwischen mindestens zwei Fahrzeugen zu ermöglichen, um Gefahrensituationen zu verringern.The invention is therefore based on the object to enable a simple and rapid production of a situation-dependent exchange of information between at least two vehicles in order to reduce dangerous situations.
Die Aufgabe wird erfindungsgemäß gelöst durch ein Verfahren mit den Merkmalen des Anspruchs 1.The object is achieved by a method having the features of claim 1.
Der Vorteil der Erfindung liegt in der einfachen und effizienten Realisierung einer Ausgabe von individualisierten Warnungen an möglichst viele am Straßenverkehr teilnehmende Fahrzeuge, um potentiellen Gefahrenstellen zu erkennen und Gefahrensituationen zu minimieren. Des weiteren wird der Informationsgehalt der übermittelten Nachricht, die zuerst von den in der Umgebung befindlichen Fahrzeugen als "herkömmliche" Warnung wahrgenommen wird, vorteilhaft erweitert und bewertet, wobei die Verknüpfung verschiedener Signale zu einem Mehrwert führt. Vorteilhaft ist, dass durch das erfindungsgemäße Verfahren das bisher notwendige Mitführen eines Warnzeichens in einem Fahrzeug seltener notwendig wird und die Gefahr bei der Positionierung und Aufstellen eines Warnzeichens für eine Person entschärft oder überhaupt nicht mehr eintritt. Dies ist insbesondere vorteilhaft bei stark und schnell befahrenen Straßen mit hoher Unfallgefahr.The advantage of the invention lies in the simple and efficient implementation of an output of individualized warnings to as many road-engaging vehicles as possible in order to recognize potential danger spots and to minimize dangerous situations. Furthermore, the information content of the transmitted message, which is first perceived by the surrounding vehicles as a "conventional" warning, advantageously extends and evaluates, the linking of various signals resulting in added value. It is advantageous that the hitherto necessary carrying a warning sign in a vehicle is required by the inventive method less often and mitigated the risk in positioning and setting up a warning sign for a person or no longer occurs. This is particularly advantageous in high and fast roads with high risk of accidents.
Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.Further advantageous embodiments are specified in the subclaims.
Ausführungsbeispiele der Erfindung werden im Folgenden näher beschrieben.Embodiments of the invention will be described in more detail below.
Im Folgenden wird als eine Ausführungsform die Herstellung einer Kommunikationsverbindung zur Warnung von potentiellen Gefahrenstellen dargestellt. Über eine Fahrzeug-Fahrzeug oder eine Fahrzeug-Infrastruktur Kommunikation übermittelt erfindungsgemäß ein erstes Fahrzeug, dass der Warnblinker angeschaltet ist. Zusätzlich wird die Position des Fahrzeugs übertragen. Ein zweites Fahrzeug bekommt über die oben genannte Kommunikation diese Information angezeigt, falls sich das erste Fahrzeug an einer für das zweite Fahrzeug relevanten Stelle befindet. Diese relevante Stelle wird z.B. durch Kartendaten bzw. Navigation/Routenführung ermittelt und plausibilisiert. Somit wird weit vor einer nicht einsehbaren Kurve im Fahrzeug eine Warnung ausgegeben, wenn es sich bei der Information um eine relevante handelt, die anhand der übermittelten Ortsinformation des sendenden Fahrzeuges geprüft wird, ob sich das Fahrzeug im z.B. Stillstand befindet. Gleichzeitig erscheint auf einer Wiedergabeeinheit wie einem Cockpit-Display oder Head-Up Display ein Warnzeichen.In the following, as an embodiment, the establishment of a communication link for warning of potential danger spots is shown. Via a vehicle vehicle or a vehicle infrastructure communication transmits according to the invention a first vehicle that the hazard warning lights is turned on. In addition, the position of the vehicle is transmitted. A second vehicle receives this information via the above-mentioned communication, if the first vehicle is located at a relevant location for the second vehicle. This relevant location is determined, for example, by map data or navigation / route guidance and made plausible. Thus, a warning is issued far in front of a non-visible curve in the vehicle, if the information is a relevant one, which is checked on the basis of the transmitted location information of the sending vehicle, if the vehicle is in standstill, for example. At the same time, a warning symbol appears on a playback unit such as a cockpit display or head-up display.
Die Warnung wird im empfangenden Fahrzeug dem Fahrerassistenz- und Fahrzeugsicherheitssystem übermittelt. Als Fahrzeugsicherheitssysteme sind alle im Fahrzeug verfügbaren Bremssysteme mit elektronischer Regelung einsetzbar. Fahrzeugsicherheitssysteme können das Electronic Break System (EBS), das Engine Management System (EMS), Antiblockiersystem (ABS), Antriebs-Schlupf-Regelung (ASR), Elektronisches Stabilitätsprogramm (ESP), Elektronische Differentialsperre (EDS), Transmission Control Unit (TCU), Elektronische Bremskraftverteilung (EBV) und/oder Motor-Schleppmomenten-Regelung (MSR) sein. Fahrerassistenzsysteme sind elektronische Zusatzeinrichtungen in Fahrzeugen zur Unterstützung des Fahrers in bestimmten Fahrsituationen. Hierbei stehen oft Sicherheitsaspekte, aber auch die Steigerung des Fahrkomforts im Vordergrund. Diese Systeme greifen teilautonom oder autonom in Antrieb, Steuerung (z.B. Gas, Bremse) oder Signalisierungseinrichtungen des Fahrzeuges ein oder warnen durch geeignete Mensch-Maschine-Schnittstellen den Fahrer kurz vor oder während kritischer Situationen. Solche Fahrassistenzsysteme sind beispielsweise Einparkhilfe (Sensorarrays zur Hinderniss- und Abstandserkennung), Bremsassistent (BAS), Tempomat, Adaptive Cruise Control oder Abstandsregeltempomat (ACC), Abstandswarner, Abbiegeassistent, Stauassistent, Spurerkennungssystem, Spurhalteassistent/Spurassistent (Querführungsunterstützung, lane departure warning (LDW)), Spurhalteunterstützung (lane keeping support)), Spurwechselassistent (lane change assistance), Spurwechselunterstützung (lane change support), Intelligent Speed Adaption (ISA), Adaptives Kurvenlicht, Reifendruckkontrollsystem, Fahrerzustandserkennung, Verkehrszeichenerkennung, Platooning, Kolonnenfahrtassistent, Automatische Notbremsung (ANB), Auf- und Abblendassistent für das Fahrlicht, Nachtsichtsystem (Night Vision).The warning is transmitted to the driver assistance and vehicle safety system in the receiving vehicle. As vehicle safety systems, all braking systems available in the vehicle can be used with electronic control. Vehicle safety systems may include Electronic Break System (EBS), Engine Management System (EMS), Antilock Braking System (ABS), Traction Control (ASR), Electronic Stability Program (ESP), Electronic Differential Lock (EDS), Transmission Control Unit (TCU) Electronic Brake Force Distribution (EBV) and / or Engine Drag Torque Control (MSR). Driver assistance systems are electronic ancillary devices in vehicles to assist the driver in certain driving situations. Here are often safety aspects, but also the increase in ride comfort in the foreground. These systems partly autonomously or autonomously intervene in drive, control (eg gas, brake) or signaling devices of the vehicle or warn the driver shortly before or during critical situations by means of suitable man-machine interfaces. Such driver assistance systems are, for example, parking aid (sensor arrays for obstacle and distance detection), brake assist (BAS), cruise control, adaptive cruise control or proximity control (ACC), distance warning, turn assistant, traffic jam assistant, lane detection system, lane departure warning / lane assist (transverse guidance assistance, lane departure warning (LDW)), lane keeping support), lane change assistant, lane change support, Intelligent Speed Adaptation (ISA), adaptive cornering light, tire pressure monitoring system, driver condition detection, traffic sign recognition, platooning, convoy driver, Automatic emergency braking (ANB), headlamp dipping and dipping assist, night vision system.
Die optischen und akustischen Hinweise werden durch ein intuitiv erfassbares Signal des Force Feedback-Gaspedals ergänzt, das über ein Fahrerassistenzsystem an den Fahrer ausgegeben wird. Durch Gegendruck legt es dem Fahrer nahe, das Tempo zu drosseln. Diese Auslösung des Force Feedback-Gaspedals wird somit von einem defekten und nicht mehr fahrtüchtigen Fahrzeug auf der Straße angestoßen, wenn bei Aktivierung des Warnblinkers zusätzliche Informationen, wie Metainformationen vom sendenden Fahrzeug überprüft werden, aus welchem Grund der Warnblinker eingeschaltete wurde. Parallel zur Warnblinkanlage werden über die Mittel zur Kommunikation, wie ein Telematikmodul mit Hilfe der Breitbandkommunikationstechnologie DSRC (Dedicated Short Range Communication), und / oder der WLAN-Übertragung (Wireless Local Area Network), ein Warnsignal an die Telematikeinheiten der anderen Fahrzeuge im Umkreis von mehreren hundert Metern gesendet. Die Fahrer besitzen durch diese Kommunikation ausreichend Zeit, das Tempo zu drosseln und vorsichtig an die Gefahrenstelle heranzufahren.The visual and audible signals are supplemented by an intuitively detectable signal from the Force Feedback accelerator, which is output to the driver via a driver assistance system. By counter pressure it suggests the driver to slow down the pace. This triggering of the Force Feedback accelerator pedal is thus triggered by a defective and no longer roadworthy vehicle on the road, if additional information, such as meta-information from the sending vehicle are checked when activating the hazard warning lights, for which reason the hazard warning lights was turned on. In parallel to the hazard warning system, a means of communication, such as a telematic module using DSRC (Dedicated Short Range Communication) and / or Wireless Local Area Network (WLAN) transmission, provides a warning signal to the telematics units of other vehicles in the vicinity of sent several hundred meters. The drivers have sufficient time through this communication to slow down the pace and to drive carefully to the danger spot.
In einer zweiten Ausführungsform werden zur Warnblinkfunktion zusätzliche Informationen hinzugezogen und erfindungsgemäß eine Situationsanalyse für das Warnsignal gebende Fahrzeug über einen kurzen Zeitraum durchgeführt. Wird festgestellt, dass das Fahrzeug steht und keine weitere Metainformation übermittel wird, somit alle vier Räder über einen festzulegenden Zeitraum als nicht in Bewegung befindlich erfasst, wird dies als eine Parksituation, wie z.B. in zweiter Reihe ausgelegt. Fährt das Fahrzeug langsam weiter und die Warnblinkfunktion ist weiterhin aktiv, wird ein potentielles Stauende durch die empfangenen Informationen erkannt.In a second embodiment, additional information is added to the hazard warning function and, according to the invention, a situation analysis for the warning signal-emitting vehicle is carried out over a short period of time. Is found that the vehicle is stationary and no further meta-information is transmitted, thus all four wheels are detected as not being in motion over a period to be determined, this is interpreted as a parking situation, such as in the second row. If the vehicle continues to move slowly and the hazard warning function is still active, a potential jam end is detected by the received information.
Weitergehend wird, wenn das sendende Fahrzeug liegen geblieben ist und somit "das Fahrzeug sich nicht plötzlich weiterbewegen kann", wie das bei Parken in zweiter Reihe oder bei einem Auftreffen auf ein Stau-Ende der Fall ist, plausibilisiert, dass das sendende Fahrzeug steht und von sich aus, durch Nutzung der eigenen Antriebseinheit, nicht mehr fortbewegt werden kann durch technisch ermittelte Zusatzinformation, indem z.B. festgestellt wird, ob das Warndreieck aus seiner Halterung entnommen wurde, die Information der Tankanzeige, bzw. der Sensor im Tank überprüft wird oder ob die Motorhaube geöffnet ist. Des Weiteren werden sämtliche den Motor betreffende Informationen über eine Datenverbindung wie z.B. dem CAN-Bus ausgelesen. Alternativ werden die Diagnosedaten, die auf einem Diagnosestecker ausgegebenen werden, zur Bewertung des Fahrzeugzustandes herangezogen. Neben den für den Betrieb des Antriebsstranges repräsentativen Informationen wird über verschiedene technische Mittel überprüft, ob ein Reifen nicht mehr für den Betrieb geeignet ist, wie beispielsweise, wenn dieser "keine Luft mehr hat".Furthermore, if the sending vehicle has remained idle and thus "the vehicle can not move on suddenly", as is the case with second-row parking or when encountering a traffic jam end, it is made plausible that the sending vehicle is stationary and By itself, by using its own drive unit, can no longer be moved by technically determined additional information, eg is determined whether the warning triangle has been removed from its holder, the information of the fuel gauge, or the sensor is checked in the tank or if the hood is open. Furthermore, all information relating to the engine is transmitted via a data link such as e.g. read out the CAN bus. Alternatively, the diagnostic data output on a diagnostic connector is used to evaluate the vehicle condition. In addition to information representative of the operation of the powertrain, various technical means are used to verify that a tire is no longer fit for operation, such as when it "runs out of air".
Vom Fahrzeug geht aktiv Gefahr für andere aus wenn zum Beispiel Benzin ausläuft. Dies wird detektiert durch den Tanklevelsensor. Bei einer Rauchentwicklung ist ebenfalls von einer Gefahrsituation auszugehen, wobei eine Raucherkennung im Fahrzeug herangezogen wird. Unter Beobachtung der Temperatursensoren liegt eine Gefahrensituation vor, wenn die Temperatur sehr schnell über einen kurzen Zeitraum ansteigt und das Fahrzeug in Brand geraten kann. Eine Gefahrensituation liegt ebenfalls vor,wenn Z.B. ein Reifen geplatzt bzw. abmontiert ist. Diese Gefahrensituationen werden durch ein Reifendrucküberwachungssystem ermittelt. Handelt es sich bei dem Fahrzeug um einen Gefahrenguttransporter, wird die Dringlichkeit der Warnung erhöht, da in Kombination mit den obigen Meldungen die Gefahr höher ist.From the vehicle is active danger to others when, for example, gas leak. This is detected by the tank level sensor. When a smoke is also assumed to be from a hazard situation, with a smoke detection in the vehicle is used. Under observation of the temperature sensors, there is a danger situation when the temperature rises very rapidly over a short period of time and the vehicle may catch fire. A dangerous situation is also present if, for example, a tire has burst or has been removed. These hazardous situations are determined by a tire pressure monitoring system. If the vehicle is a dangerous goods transporter, the urgency of the warning is increased, since in combination with the above messages the danger is higher.
Vom Fahrzeug geht aktiv Gefahr für andere aus:
- Benzin läuft aus (über Tanklevelsensor zu erkennen)
- Raucherkennung (Fahrzeug könnte brennen)
- Temperatur steigt sehr schnell sehr stark an (Fahrzeug könnte brennen)
- Reifen ist geplatzt (irgendwo müssen noch Reifenteile sein)
- Reifen fehlt (der muss auch irgendwo sein)
- Fahrzeug ist ein Gefahrenguttransporter (in Kombination mit den obigen Meldungen noch gefährlicher!)
- Gasoline runs out (can be detected via tank level sensor)
- Smoke detection (vehicle could burn)
- Temperature rises very fast very quickly (vehicle could burn)
- Tire has burst (some parts have to be left)
- Tire is missing (it has to be somewhere)
- Vehicle is a dangerous goods transporter (in combination with the above messages even more dangerous!)
In einer weiteren Ausführungsform werden noch zusätzlich die Informationen über die geschlossene oder geöffnete Zugangsvorrichtung zum Fahrzeug überwacht und zur Plausibilisierung herangezogen. Als Zugangsvorrichtungen sind alle Einstiegmöglichkeiten, wie Türen, Klappen, Hauben und Verdecke gemeint, die es einer Person ermöglichen in das Fahrzeuginnere zu gelangen. Es wird beispielsweise überprüft, ob eine Tür oder der Kofferraum geöffnet ist. Ist beispielsweise eine Tür geöffnet und der Warnblinker aktiv, wird darauf geschlossen, dass eine Gefahr besteht, dass sich Personen auf der Fahrbahn befinden und der Ortsbereich des Fahrzeuges durch nicht einsehbare weitere Gefahrenobjekte, wie Fußgänger auf der Straße, bezüglich des potetiellen Gefahrenpotentials höher einzustufen ist.In a further embodiment, the information about the closed or opened access device to the vehicle is additionally monitored and used for plausibility checking. As access devices are all entry options, such as doors, flaps, hoods and covers meant, which allow a person to get into the vehicle interior. It is checked, for example, whether a door or the trunk is open. For example, if a door is open and the hazard warning lights active, it is concluded that a There is a risk that people are on the road and the local area of the vehicle is classified by non-visible further danger objects, such as pedestrians on the road, with respect to the potential hazard potential higher.
Diese zusätzlichen Informationen werden ebenfalls dem Fahrer des zweiten Fahrzeugs angezeigt, falls die Information durch eine eigene Situationsanalyse als relevant eingestuft wird.This additional information is also displayed to the driver of the second vehicle, if the information is classified as relevant by a separate situation analysis.
