Description
Die vorliegende Erfindung betrifft ein Verfahren zur Steuerung eines Warnsignals eines Abstandswarnsystems. Anwendung findet das Verfahren in Kraftfahrzeugen, insbesondere in Kraftfahrzeugen mit Abstandsregelsystem.The The present invention relates to a method for controlling a Warning signal of a distance warning system. Application finds the method in motor vehicles, especially in motor vehicles with distance control system.
Ein
Verfahren zur automatischen Abstandsregelung ist z. B. in der Offenlegungsschrift
Ein
weiteres Verfahren zur Regelung des Abstands zwischen fahrenden
Kraftfahrzeugen ist in der Patentschrift
Es ist nahe liegend in einem solchen Abstandsregelsystem auch eine Warnung des Fahrers vorzusehen, wenn ein vorgegebener Mindestsicherheitsabstand unterschritten wird und somit eine kritische Situation eintreten könnte. Unabhängig davon sind auch separate Abstandsmesssysteme mit Warnvorrichtung bekannt, die dem Fahrer signalisieren, wenn ein vorgegebener Mindestabstand unterschritten wird. Ein Beispiel für ein solches System ist die Einparkhilfe auf der Basis von Ultraschallsensoren.It is obvious in such a distance control system also one Warning the driver if a given minimum safe distance falls below and thus enter a critical situation could. Independently of these are also separate distance measuring systems with warning device known to signal the driver when a predetermined minimum distance is fallen short of. An example of such a system is the parking aid on the basis of ultrasonic sensors.
Ein Nachteil eines solchen abstandsabhängigen Warnsignals kann darin liegen, dass trotz bereits eingeleiteter kollisionsvermeidender Maßnahmen, weiterhin ein Warnsignal an den Fahrer ausgegeben wird. Dies wird i. d. R. von einem bereits aufmerksamen Fahrer als störend empfunden und mindert die Aktzeptanz eines solchen Systems beim Kunden.One Disadvantage of such a distance-dependent warning signal can therein lie that despite already initiated collision avoiding Activities, continue to issue a warning signal to the driver. this will i. d. R. by an already attentive driver as disturbing and reduces the acceptance of such a system by the customer.
Die Aufgabe der Erfindung liegt also darin, ein entsprechend verbessertes Verfahren zur Steuerung eines Warnsignals eines Abstandswarnsystems anzugeben.The The object of the invention is therefore a correspondingly improved Specify a method for controlling a warning signal of a distance warning system.
Diese Aufgabe wird gemäß einer Anordnung nach Patentanspruch 1 gelöst. Die abhängigen Patentansprüche zeigen vorteilhafte Ausführungsformen und Weiterentwicklungen der Erfindung auf.These Task is done according to a Arrangement according to claim 1 solved. The dependent claims show advantageous embodiments and further developments of the invention.
Es wird ein Verfahren zur Steuerung eines Warnsignals eines Abstandswarnsystems in Kraftfahrzeugen, insbesondere in Kraftfahrzeugen mit Abstandsregelsystem, vorgestellt. Das Abstandswarnsystem gibt ein Warnsignal aus, sobald ein vorgegebener Mindestabstand zum vorausfahrenden Fahrzeug unterschritten wird. Das hier vorgestellte Verfahren berücksichtigt erfindungsgemäß eine nach dieser ersten Warnung eintretende erkennbare Fahrerreaktion bzw. erkennbare Fahrerabsicht für das weitere Warnverhalten. Wird eine Fahrerreaktion bzw. erkennbare Fahrerabsicht erkannt, wird keine weitere, in ihrer Dringlichkeit höhere Warnstufe aktiviert. Eine Warnstufe höherer Dringlichkeit würde in einem Abstandswarnsystem gemäß dem Stand der Technik z. B. durch einen noch weiter verringerten Abstand zum vorausfahrenden Fahrzeug ausgelöst. Denkbar ist auch, dass in einem Abstandswarnsystem gemäß dem Stand der Technik eine Warnstufe höherer Dringlichkeit eingesetzt wird, wenn der Mindestsicherheitsabstand längere Zeit unterschritten wird. Es wird angenommen, dass die Aufmerksamkeit des Fahrers durch eine weniger dringliche Warnstufe nicht geweckt wurde. Warnsignale mit verschieden Dringlichkeitsstufen können z. B. durch verschiedene Signalarten wie z. B. ein optisches, akustisches oder haptisches Signal umgesetzt werden und/oder durch verschiedene Signalstärken, Wiederholfrequenzen, Tonhöhen etc.It discloses a method for controlling a warning signal of a distance warning system in motor vehicles, in particular in vehicles with a distance control system, presented. The distance warning system will give a warning signal as soon as a predetermined minimum distance to the vehicle in front falls below becomes. The method presented here takes into account according to the invention one after this first warning occurring recognizable driver reaction or recognizable Driver intent for the further warning behavior. Will a driver reaction or recognizable Driver's intention is recognized, no further, in their urgency higher Warning level activated. A warning level of higher urgency would be in one Distance warning system according to the state the technology z. B. by an even further reduced distance to preceding vehicle. Conceivable is also that in a distance warning system according to the prior art a Warning level higher Urgency is used when the minimum safety distance longer Time is undershot. It is believed that the attention of the driver not awakened by a less urgent warning level has been. Warning signals with different levels of urgency z. B. by different types of signals such. B. an optical, acoustic or haptic signal are converted and / or by different signal strengths, repetition frequencies, pitches Etc.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass nach einem ersten Warnsignal und einer erkennbaren Fahrerreaktion bzw. erkennbare Fahrerabsicht keine weitere Warnung mehr erfolgt. In einer dritten Ausgestaltung der Erfindung werden nach einem ersten Warnsignal und einer erkennbaren Fahrerreaktion bzw. erkennbare Fahrerabsicht nur noch optische bzw. in ihrer Dringlichkeit gering einzustufende Warnsignale ausgegeben, auch wenn der vorgegebene Mindestabstand zum vorausfahrenden Fahrzeug weiterhin unterschritten wird.A Another embodiment of the invention provides that after a first Warning signal and a recognizable driver reaction or recognizable driver intention no further warning is given. In a third embodiment The invention is based on a first warning signal and a recognizable Driver reaction or recognizable driver intention only optical or in their urgency issued low warning signals, even if the predetermined minimum distance to the vehicle in front continues to fall below.
In einer vorteilhaften Ausführungsform der Erfindung die Betätigung der Bremse ab einem vorgegebenen Schwellwert der Bremskraft als erkennbare Fahrerreaktion gewertet. In einer besonderen Ausgestaltung der Erfindung beträgt der vorgegebene Schwellwert ca. 40% der maximalen Bremskraft.In an advantageous embodiment the invention, the operation the brake from a predetermined threshold of the braking force as recognizable driver reaction scored. In a particular embodiment of the invention the predetermined threshold is about 40% of the maximum braking force.
Vorzugsweise wird als eine erkennbare Fahrerreaktion bzw. erkennbare Fahrerabsicht die Betätigung der Gaspedals bzw. einer Vorrichtung zur Beschleunigung des Fahrzeugs ab einem vorgegebenen Schwellwert der Beschleunigungskraft erkannt. In einer vorteilhaften Ausgestaltung der Erfindung beträgt der vorgegebene Schwellwert ca. 40% der maximalen Beschleunigungskraft. Das beschriebene Fahrerverhalten deutet auf einen geplanten Überholvorgang hin, d. h. der Fahrer hat die Gefahrensituation erfasst und Maßnahmen zur Kollisionsvermeidung eingeleitet. Ein geplanter Überholvorgang kann ebenso durch die Betätigung einer Vorrichtung zur Spurwechselanzeige bzw. durch eine Lenkbewegung des Fahrzeugführers eingeleitet werden. Auch diese Fahrerreaktionen werden in einer besonderen Ausgestaltung der Erfindung als eine erkennbare Fahrerabsicht gewertet und das Warnsignal entsprechend gesteuert.Preferably, as an identifiable driver reaction or recognizable driver intent, the operation of the accelerator pedal or a device for accelerating the vehicle is detected from a predetermined threshold value of the acceleration force. In an advantageous embodiment of the invention, the predetermined threshold is about 40% of the maximum acceleration force. The described driver behavior indicates a planned overtaking process, ie the driver has detected the dangerous situation and measures for collision avoidance initiated. A planned overtaking operation can also be initiated by the operation of a device for lane change indication or by a steering movement of the driver. These driver reactions are evaluated in a particular embodiment of the invention as a recognizable driver intent and the warning signal controlled accordingly.
Weitere Vorteile und Besonderheiten der Erfindung werden anhand eines Ausführungsbeispiels näher erläutert.Further Advantages and features of the invention will be explained in more detail with reference to an embodiment.
Als ein Ausführungsbeispiel der Erfindung werden zwei Fahrzeuge angegeben, die sich hintereinander auf einer Fahrspur mit gleicher Fahrtrichtung bewegen. Das Folgefahrzeug verfügt über ein Abstandsregelsystem, das die Distanz zu einem vorausfahrenden Fahrzeug bestimmt und die Fahrgeschwindigkeit des Fahrzeugs der des voran fahrenden Fahrzeugs anpasst.When an embodiment The invention provides two vehicles, which are consecutively Move on a lane with the same direction of travel. The following vehicle has a distance control system, which determines the distance to a vehicle ahead and the Driving speed of the vehicle that of the preceding vehicle adapts.
Zunächst erfolgt eine Zufahrt auf das relevant eingestufte Objekt. Bewegt sich das folgende Fahrzeug mit einer höheren Geschwindigkeit als das voran fahrende Fahrzeug (das relevante Objekt), regelt das Abstandsregelsystem die Fahrzeuggeschwindigkeit auf das Niveau des voran fahrenden Fahrzeugs, wenn der Fahrer nicht in die Abstandsregelung eingreift. Während der Folgefahrt wird ein definierter Sollabstand eingestellt.First of all an access to the relevant classified object. Does that move? following vehicle with a higher Speed as the leading vehicle (the relevant object), The distance control system regulates the vehicle speed on the Level of the vehicle ahead, if the driver is not in the Distance control intervenes. While The following travel is set a defined nominal distance.
Im Falle des Überholwunsches durch den Fahrzeugführer wir dieser das Abstandsregelsystem durch ein eigenes Fahrmanöver, eine Betätigung des Gaspedals, überstimmen. Unterschreitet der Fahrer durch die selbst gewählte Fahrzeuggeschwindigkeit bestimmte Abstandsschwellen zum detektierten Objekt, erfolgen Abstandswarnungen. In einem Abstandsregelsystem nach dem Stand der Technik würden diese Warnungen nach dem Unterschreiten bestimmter Abstandsschwellen erfolgen, z.B. zunächst durch eine optische Symbolanzeige, später durch ein kurzes akustisches Warnsignal und schließlich durch eine dauerhafte akustische Warnung. Nach dem hier angegebenen Verfahren zur Steuerung eines Warnsignals unterbleibt zumindest die dauerhafte akustische Warnung da eine Fahrerabsicht, eine Betätigung des Gaspedals bzw. des Blinkers, erkannt wird.in the Trap of passing desire by the driver we have this the distance control system through its own driving maneuver, one activity of the accelerator, override. If the driver falls below the self-selected vehicle speed certain Distance thresholds to the detected object, distance warnings are made. In a prior art proximity control system, these would Warnings after falling below certain distance thresholds, e.g. first through an optical symbol display, later by a short acoustic warning signal and finally by a permanent acoustic warning. Following the procedure given here to control a warning signal is omitted at least the permanent Acoustic warning as a driver intention, an actuation of the Accelerator or the turn signal is detected.
