Abstract
Description
Die Erfindung betrifft einen Sicherheits-Computer, mit dem Auffahrunfälle auf vorausfahrende Fahrzeuge durch fehlerhafte Abstandseinschätzung aus Unkenntnis der Einflüsse von Reaktionszeit und Bremsweg vermieden werden sollen. Außerdem soll dem Folgefahrzeug ein Signal gegeben werden, wenn der Abstand so gering geworden ist, daß bei plötzlicher Bremsung ein Unfall unvermeidlich wird.The invention relates to a security computer with the rear-end collision on vehicles ahead incorrect distance assessment due to ignorance of the Influences of reaction time and braking distance avoided should be. In addition, the following vehicle is supposed to Be given a signal when the distance has become so small is that in the event of sudden braking an accident becomes inevitable.
Dieser Sicherheits-Computer wird als Zusatzeinrichtung für Automobile erforderlich, weil ab Januar 1993 Autofahrer bestraft werden, wenn sie bei 80 km/h Geschwindigkeit den Abstand des halben Tachowertes unterschreiten. Da aber der Autofahrer bislang den Abstand nur nach der Länge der weißen Mittelstreifen mit den Zwischenräumen auf den Autobahnen abschätzen kann und diese Methode der Abstandsermittlung gefährlich ist, weil sie zu sehr ablenkt, wird eine Meßeinrichtung im Fahrzeug dringend erforderlich.This security computer is called Additional equipment for automobiles required because from January 1993 motorists are punished if they are at 80 km / h speed the distance of half the speedometer value fall below. But since the driver has so far Distance only according to the length of the white median strips estimate with the gaps on the highways can and this method of distance determination is dangerous because it becomes too distracting Measuring device in the vehicle is urgently required.
Außerdem soll ab Januar 1993 das dritte Bremslicht in der Mitte des Fahrzeugs Vorschrift werden, das sich als Blinklicht für Drängler anbietet, wenn sie den absolut notwendigen Sicherheitsabstand unterschreiten.In addition, from January 1993 the third brake light in the middle of the vehicle, which turns out to be Flashing light for drainers offers, if they absolutely fall below the necessary safety distance.
Bei der Entwicklung eines Sicherheits-Computers liegt es nahe, das Gerät entsprechend den Ansprüchen 1 und 2 auch zur Absicherung des Fahrzeugs zu verwenden. Hier gibt es eine neue Fülle von Möglichkeiten, wobei die Entnahme des Gerätes mit Hilfe einer Steck- und Führungsvorrichtung die einfachste ist, um mit Sicherheit zumindest den Diebstahl des Computers oder der Module zu vermeiden. Außerdem können die Geräte im Störungsfall schnell durch eine Ersatzeinheit ausgetauscht werden.When developing a security computer lies it close, the device according to claims 1 and 2 can also be used to secure the vehicle. Here there is a new abundance of possibilities, the Removal of the device using a plug and Guide device is the easiest to use Security at least the theft of the computer or to avoid the modules. In addition, the devices in the In the event of a fault, a replacement unit can be used quickly be replaced.
Die Verwendung eines Codes entsprechend Anspruch 2, der in den Computer zur Betriebsbereitschaft des Fahrzeugs eingegeben werden soll, kann in besonderen Fällen wichtig sein, um sicherzustellen, daß nur bestimmte Personen das Fahrzeug benutzen können.The use of a code according to claim 2, the in the computer for the operational readiness of the Vehicle can be entered in special Cases to be important to make sure that only certain people can use the vehicle.
Anspruch 4 der Erfindung behandelt die Abstandsmes sung mit Ultraschall, Radar, Laser und Video-Kameras. Ultraschall läßt sich wahrscheinlich nur für Entfernungen bis etwa 20 m anwenden, reicht also zur Entfernungsmessung des vorausfahrenden Fahrzeugs nicht aus. Auch die Radar- und Lasermessung sind schwierig anwendbar, weil entgegenkommende Fahrzeuge die Radarmessung stören und bei Kurvenfahrten der Laserstrahl nur schwierig reflektiert werden kann. Man braucht hierfür komplizierte Führungsgeräte.Claim 4 of the invention deals with the distance measuring solution with ultrasound, radar, laser and video cameras. Ultrasound can probably only be used for Using distances of up to about 20 m is sufficient for Distance measurement of the vehicle in front is not out. Radar and laser measurement are also difficult applicable because oncoming vehicles Disturb radar measurement and when cornering the Laser beam can be reflected only with difficulty. Man needs complicated guidance devices for this.
Leichter dagegen ist die Abstandsmessung mit einer einfachen Video-Kamera, da das vorausfahrende Fahrzeug mit zunehmender Entfernung immer kleiner wird und somit die Größe des Fahrzeuges im Bild ein Maß für die Entfernung ist. Zeichnet man mit dem Computer eine horizontale Linie, deren Höhe von der Geschwindigkeit des Fahrzeuges bestimmt wird, so kann man diese so einstellen, daß sie beim Abstand des halben Tachowertes der Höhe des Fahrzeugs entspricht. Eine zweite Linie sollte vielleicht am Berührungspunkt der Räder mit dem Boden gezogen werden.The distance measurement is easier with a simple video camera as the vehicle in front with increasing distance it gets smaller and smaller the size of the vehicle in the picture is a measure of that Distance is. If you draw one with the computer horizontal line whose height depends on the speed the vehicle is determined, so you can this adjust that they are at the distance of half the speedometer value corresponds to the height of the vehicle. A second line should perhaps be at the point of contact of the wheels with the Ground.
Ist nun die Entfernung zum vorausfahrenden Fahrzeug kleiner als vorgeschrieben, so schneidet die obere Linie das Fahrzeug und man erkennt, daß man den Abstand durch eine kleinere Motordrehzahl wieder vergrößern sollte. Liegt die obere Linie dagegen über dem Fahrzeug, so ist der Abstand größer als vorgeschrieben und damit sicher ausreichend. Da die Abstandsmessung mit der normalen Video-Kamera nur bei Tageslicht, funktioniert, empfiehlt es sich, gegebenenfalls eine Infrarot-Kamera zu verwenden, die auch nachts noch die Abstandsmessung ermöglicht.Now is the distance to the vehicle in front smaller than prescribed, the upper one cuts Line the vehicle and you can see that you can see the distance increase again with a lower engine speed should. On the other hand, the top line is above that Vehicle, the distance is greater than prescribed and therefore certainly sufficient. Because the distance measurement with the normal video camera only in daylight, works, it is recommended to use one if necessary Infrared camera to use that even at night Distance measurement enabled.
In den Serienfahrzeugen werden auf Wunsch heute schon Geschwindigkeitsregler eingebaut, die eine vorgewählte Geschwindigkeit des Fahrzeugs konstant halten. Somit ist auch gemäß Anspruch 5 die Möglichkeit gegeben, durch einen Vergleich von Fahrzeuggröße und Geschwindigkeit im Computer ein Signal zu errechnen und dem Geschwindigkeitsregler zuzuführen, das den Abstand zum vorausfahrenden Fahrzeug auf den vorgeschriebenen Wert konstant hält. Parallel dazu kann der Fahrer mit dem Gashebel, z. B. für Überholvorgänge, eingreifen und das Fahrzeug selbst fahren.On request, the series vehicles are already available today Speed controller built in, which is a preselected Keep vehicle speed constant. Consequently there is also the possibility according to claim 5 by comparing vehicle size and Speed in the computer to calculate a signal and to the speed controller that feed the distance to the vehicle in front on the prescribed Value keeps constant. In parallel, the driver can use the throttle, e.g. B. for overtaking, intervene and drive the vehicle yourself.
Fährt ein Fahrer zu eng auf das vorausfahrende Fahrzeug auf, so gibt es einen Mindestabstand, der bei plötzlicher Bremsung des Vorderwagens zum Auffahrunfall führt. Dieser Wert, vielleicht mit einem Sicherheitsbetrag, soll dem Fahrer optisch oder akustisch signalisiert werden, weil meistens den Fahrern das physikalische Verständnis über Auffahrunfälle fehlt. Besser als die Warnung erscheint eine automatische Verringerung der Geschwindigkeit durch den Computer mit dem Geschwindigkeitsregler. Erkennt der Rechner die schnelle Verringerung des Abstandes zum vorausfahrenden Fahrzeug und ermittelt er hieraus einen voraussehbaren Auffahrunfall, so soll die Bremsung automatisch durchgeführt werden.If a driver drives too closely to the one ahead Vehicle on, there is a minimum distance at sudden braking of the front end to a rear-end collision leads. That value, maybe with one Security amount, should the driver optically or be signaled acoustically, because mostly Drivers physical understanding about Rear-end collisions are missing. Better than the warning appears an automatic reduction in speed through the computer with the speed control. Does the computer recognize the rapid reduction in Distance to the vehicle in front and determines it from a predictable rear-end collision, the Braking can be carried out automatically.
Mit Anspruch 6 der Erfindung soll die Unfallgefahr durch ein folgendes Fahrzeug verringert werden, indem mit einem Ultraschall-Meßgerät der kritische Abstand gemessen wird, bei dessen Unterschreitung es im Falle eines plötzlichen Bremsvorganges zum Auffahrunfall kommt. (Falls dieser Abstand nicht größer als etwa 20 m ist!). Der Computer verarbeitet das Signal des Ultraschallgerätes zu einem Blinksignal, dessen Dauer und Leerpause eingestellt werden können, damit es nicht als Dauerblinklicht den Fahrer zu sehr provoziert, der auf Grund seiner größeren Fahrzeugleistung überholen möchte. Als Blinklicht könnte das dritte Bremslicht verwendet werden, das Anfang 1993 in alle Pkw's per Gesetz eingebaut werden soll.With claim 6 of the invention, the risk of accidents be reduced by a following vehicle by the critical distance with an ultrasonic measuring device is measured, below which it falls in the case a sudden braking process to a rear-end collision is coming. (If this distance is not greater than about 20 m is!). The computer processes the signal from the Ultrasound device for a flashing signal, its duration and white break can be set so it doesn't as a steady flashing light provokes the driver too much overhaul due to its greater vehicle performance would like to. The third brake light could be used as a flashing light used in early 1993 in all cars Law should be incorporated.
Wird der kritische Grenzabstand genügend schnell durchfahren, wie z. B. an Ampeln und im Stau, so erfolgt kein Blinken. Das gilt auch für das Anfahren der Pkw's.The critical limit distance becomes fast enough drive through, such as B. at traffic lights and in a traffic jam, is done no blinking. This also applies to starting the cars.
Autofahrer, besonders wenn sie durch Mitfahrer abgelenkt werden, übersehen häufig die Schilder mit vorgeschriebener Maximalgeschwindigkeit. Die Ansprüche 6 und 7 der Erfindung gehen davon aus, daß die Fahrbahnen in der Höhe der Schilder streifenartige Markierungen erhalten, die ein Sensor abtastet und dem Computer mitteilt. Breite und Abstand der Markierungen ergeben beim Abtasten Signale, die im Computer zur Geschwindigkeitsangabe verarbeitet und angezeigt werden, solange, bis eine neue Vorgabe erfolgt. Der Fahrer kann sich also ständig informieren, welche Geschwindigkeit einzuhalten ist. Mit dem Computer kann aber auch entsprechend Anspruch 5 die vorgeschriebene Geschwindigkeit des Fahrzeuges automatisch eingestellt und konstant gehalten werden.Motorists, especially when driven by passengers are distracted, often overlook the signs prescribed maximum speed. The requirements 6 and 7 of the invention assume that the Roadways at the height of the signs are strip-like Receive markings that a sensor scans and the Computer communicates. Width and spacing of the markings result when scanning signals that are used in the computer Speed information processed and displayed until a new specification is made. Of the Drivers can always find out which ones Speed must be maintained. With the computer can but also the prescribed according to claim 5 Vehicle speed set automatically and be kept constant.
Die Fahrbahnmarkierungen können jederzeit auf Straßen und Autobahnen aufgebracht werden, z. B. als Farbstreifen, mit Schmelz-Kunststoff-Klebern, mit Farb- Zement-Mischungen, als Bitumenkleber mit Magnetpulver zusätzen für induktive Geber etc. Hier sind die Erfahrungen der Straßenbauer zu berücksichtigen.The lane markings can be on roads at any time and highways are applied, e.g. B. as Color strips, with melt plastic glue, with color Cement mixtures, as bitumen adhesive with magnetic powder additions for inductive sensors etc. Here are the Consider the experience of road builders.
Die gleichen Einrichtungen und Mittel sind auch gemäß Anspruch 7 für die Ortsanzeige anwendbar. Man verwendet hierfür die gleichen Sensoren und Fahrbahnmarkierungen, nur die Zahl- und Ausführung der Streifen entsprechend dem Informationsinhalt, z. B. mit dem Bar-Code, ändert sich.The same facilities and resources are also in accordance Claim 7 applicable to the location display. One uses the same sensors and road markings for this, only the number and design of the strips accordingly the information content, e.g. B. with the bar code changes yourself.
Um die Ortsbestimmung richtig nutzen zu können, gibt man in den Computer das Fahrziel ein. Mit der Anzeige des jeweiligen Ortes und des Fahrzieles wird die jeweilige Distanz in km angezeigt. Um das Einlesen des Fahrzieles leicht zu machen, kann man hierfür z. B. einen Bar-Code-Griffel und eine Städtetabelle mit Barcode verwenden.In order to be able to use the location correctly, there are one into the computer the destination. With the ad of the respective place and the destination is the respective distance is shown in km. To read the To make the destination easy, you can do this e.g. B. with a bar code stylus and a city table Use barcode.
Die Ansprüche 9 bis 13 der Erfindung betreffen die automatische Lenkung des Fahrzeugs. Sie erfordert einen zusätzlichen Lenkantrieb für Automatikbetrieb, z. B. elektromotorisch, hydraulisch oder pneumatisch, einen Führungsstreifen auf der Straße oder auf der Autobahn, einen Sensor und den Computer für die Signalverarbeitung und Ausgabe. Der Antrieb ist so konzipiert, daß der Fahrer ständig eingreifen und die Lenkautomatik korrigieren kann. Auch wenn man der Meinung ist, eine Automatiklenkung sei überflüssig, so ist sie doch im Zusammenhang mit den Ansprüchen 4 bis 8 von nicht zu unterschätzender Bedeutung, besonders für Fahrer von langen Strecken. Automatische Lenkung sollte auch automatisches Fahren mit automatisch eingehaltenen Sicherheitsabständen sein.Claims 9 to 13 of the invention relate to the automatic steering of the vehicle. It requires one additional steering drive for automatic operation, e.g. B. electric motor, hydraulic or pneumatic, one Lane on the street or on the highway, a sensor and the computer for that Signal processing and output. The drive is like that designed to constantly intervene and the driver Automatic steering can correct. Even if you are the Opinion is that automatic steering is superfluous, so it is in connection with claims 4 to 8 of importance not to be underestimated, especially for Long distance drivers. Automatic steering should also automatic driving with automatically adhered to Safety distances.
In der Regeltechnik beginnt die Fuzzy-Logik immer größere Bedeutung zu bekommen. In Anspruch 14 soll deshalb sicher gestellt werden, daß dieses Prinzip zur Anwendung kommen soll, wenn Experimente zeigen sollten, daß hiermit eine größere Zuverlässigkeit bei besserem Regelverhalten erzielt werden kann.Fuzzy logic always starts in control technology to get more meaning. In claim 14 should therefore be ensured that this principle for Should be used if experiments should show that hereby greater reliability with better Control behavior can be achieved.
Der Anspruch 15 der Erfindung ist eine Möglichkeit, das Problem der Übermüdung der Fahrer etwas besser zu beherrschen, wenn der gute Wille da ist. Bei LKW'S und Personen-Bussen könnte zusätzlich eine Zwangspause gesetzlich eingeführt werden, die den Fahrern einen Rechtsanspruch auf Ruhepausen gewährleistet.Claim 15 of the invention is a possibility the problem of driver fatigue a little better master when the good will is there. With trucks and Passenger buses could also take a break be introduced by law to give drivers a Legal entitlement to rest breaks guaranteed.
Meistens nehmen Autofahrer die gefahrene Zeit nicht zur Kenntnis. Erst wenn die Augen vor Übermüdung kurz zufallen und sie angstvoll auf den nächsten Blackout warten, bemühen sie sich, einen Parkplatz für einen kurzen Schlaf zu erreichen. Das kann aber manchmal zu spät sein. Deshalb kann die Fahrzeitmessung mit selbst gewählter Fahrzeit und Signalisierung des Endes dieser Fahrzeit durchaus ein sicheres Mittel sein, Unfälle durch Übermüdung zu vermeiden.Mostly, drivers do not take the time driven note. Only when the eyes short of fatigue fall and they fearful of the next blackout wait, strive to find a parking space for one to achieve short sleep. But sometimes that can be late. Therefore, the travel time measurement with yourself selected travel time and signaling the end of this Driving time can be a safe means of accidents to avoid fatigue.
Die Ansprüche 16 bis 18 der Erfindung behandeln die Ausführungsmöglichkeiten. Eine Kombination mit dem Autoradio soll zwar möglich sein, ist aber wohl keine optimale Lösung. Wenn die Funktionsmodule entwickelt werden, ist wohl die Anwendung eines einzelnen Moduls, z. B. für die Abstandsmessung, zunächst zu erwarten.Claims 16 to 18 of the invention deal with the Execution options. A combination with that Car radio should be possible, but is probably not optimal solution. When the functional modules are developed is probably the use of a single module, e.g. B. for distance measurement, to be expected initially.
Ein Sicherheits-Computer mit allen Funktionen der Erfindung würde wohl etwa die Größe eines Autoradios haben, einen kleinen Monitor besitzen, und könnte ähnlich wie dieses im Auto eingebaut werden.A security computer with all the functions of Invention would probably be about the size of a car radio have a small monitor, and could similar to this to be installed in the car.
