Die Geschwindigkeitsdifferenz zu voranfahrenden Fahrzeugen wird hierbei durch Bestimmung der Höhe der sich ergebenden Dopplerfrequenz und die Entfernung der angemessenen Fahrzeuge aus der Empfangssignalstärke ermittelt.CW radar device with separate transmitting and receiving antennas on the The front of the motor vehicle equipped with this collision protection system is rigidly mounted are and antenna directional diagrams that extend in the direction of travel of the vehicle parallel to its longitudinal axis, approximately up to 300 m in front of the vehicle, extend and the detection of moving vehicles located in this area by utilizing the Doppler effect in the radar device. The speed difference to preceding vehicles is determined by determining the amount of the resulting Doppler frequency and the distance of the appropriate vehicles from the received signal strength determined.
Auffahrunfälle durch nicht mit einer derartigen Warnanlage ausgerüstete, dem Träger der Warnanlage folgende Fahrzeuge sind hierdurch nicht vermeidbar.Rear-end collisions caused by not equipped with such a warning system, Vehicles following the person carrying the warning system cannot be avoided as a result.
Der Erfindung liegt die Aufgabe zugrunde, eine Warnanlage für Straßenfahrzeuge, insbesondere für Kraftwagen, anzugeben, die den Führer eines Fahrzeuges, das von hinten auf das Trägerfahrzeug der Warnanlage aufzufahren droht, möglichst eindringlich d rechtzeitig vor dem drohenden Auffahrunfall warnt.The invention is based on the object of providing a warning system for road vehicles, in particular for motor vehicles, to indicate the driver of a vehicle driven by threatens to collide with the carrier vehicle of the warning system, as urgently as possible d warns of the impending rear-end collision in good time.
Die Erfindung besteht bei einer Warnanlage der einleitend genannten Art darin, daß der Wirkungsbereich der Meßeinrichtung entgegen der normalen Bahrtrichtuag des Trägerfahrzeuges der Warnanlage gerichtet ist, daß die Meßeinrichtung zusätzlich an sich bekannte Mittel zur Unterscheidung kommender von gehenden Zielen (Fahrtrichtungstrennung) enthält und daß die Warnanlage in Abhängigkeit einerseits von der Relativgeschwinaigkeit ihres Trägerfahrzeuges zu einem im Wirkungsbereich der Meßeinrichtung befindlichen "kommenden" anderen Fahrzeug und andererseits von dem gegenseitigen momentanen Abstand des Trägerfahrzeugs zu dem anderen Fahrzeug solche vorgegebenen Warnsignale abgibt, die vom Führer des anderen Fahrzeugs wahrgenommen werden können.The invention consists in a warning system of the type mentioned in the introduction Kind in that the scope of the Measuring device against the normal Bahrtrichtuag of the carrier vehicle of the warning system is directed that the Measuring device additionally means known per se for differentiating coming from going goals (travel direction separation) and that the warning system as a function on the one hand from the relative speed of your carrier vehicle to one in the effective area the measuring device located "coming" other vehicle and on the other hand from the mutual current distance of the carrier vehicle to the other vehicle emits such predetermined warning signals that are perceived by the driver of the other vehicle can be.
Üblicherweise wird der Wirkungsbereich der Meßeinrichtung der erfindungsgemäßen Warnanlage somit vom Heck des Fahrzeugs weggerichtet sein und wird sich die Meßeinrichtung oder zumindest deren Antenne im Heck des Trägerfahrzeugs der Warnanlage befinden. Vorteilhafterweise findet als Neßeinrichtung der erfindungsgemäßen Warnanlage ein CW/FM-Radargerät Verwendung, wobei CW die übliche Abkürzung für impulsfrei (continuous wave) und FM die übliche Abkürzung für Frequenzmodulation bedeuten. Die ggf. kombinierte Sende- und/oder Empfangsantenne der erfindungsgemäßen Warnanlage ist bei Verwendung eines Kraftwagens als Trägerfahrzeug vorteilhaft im hinteren Stoßfänger des Trägerfahrzeuges angeordnet oder als dessen hinterer Stoßfänger ausgebildet. Als Geber der Warnsignale findet bei der erfindungsgemäßen Warnanlage vorzugsweise eine Blinklampe Verwendung, deren Blinkfrequenz zweckmäßigerweise in Abhängigkeit von der Höhe der Kollisionsgefahr gewählt ist.Usually, the range of action of the measuring device is that of the invention Warning system will thus be directed away from the rear of the vehicle and will be the measuring device or at least their antenna is located in the rear of the carrier vehicle of the warning system. The warning system according to the invention is advantageously used as the measuring device CW / FM radar device use, where CW is the usual abbreviation for impulse-free (continuous wave) and FM are the usual abbreviations for frequency modulation. The possibly combined Transmitting and / or receiving antenna of the warning system according to the invention is in use one Motor vehicle as a carrier vehicle is advantageous in the rear bumper the carrier vehicle arranged or designed as its rear bumper. The warning system according to the invention is preferably used as a transmitter of the warning signals Use a flashing lamp, the flashing frequency of which is expediently dependent is selected on the level of the risk of collision.
Die von der Meßeinrichtung der erfindungsgemäßen Warnanlage vorwiegend in Fahrbahnkrümmungen erfaßten Objekte neben der Fahrspur, z. B. Bäume, Masten, Schilder, sind automatisch in an sich bekannter Weise als "gehende" Ziele erkennbar und werden deshalb für die Warnsignalgabe nicht ausgewertet* Ein mit höherer als der eigenen Fahrgeschwindigkeit von hinten sich näherndes Fahrzeug wird Jedoch von der Meßeinrichtung der erfindungsgemäßen Warnanlage gemeldet, wobei bei Unterschreiten eines von der relativen Annäherungsgeschwindigkeit abhängigen gegenseitigen Fahrzeugabstandes zwischen dem Trägerfahrzeug und den denselben folgenden Fahrzeug die vorgegebenen Warnsignale abgegeben werden. Die Entfernungsmessung erfolgt bei der erfindungsgenßen Warnanlage vorzugsweise durch Benutzung und Auswertung einer Frequenzmodulation der Sendesignale der Rückstrahlmeßeinrichtung.The predominantly of the measuring device of the warning system according to the invention Objects detected in lane curvatures next to the lane, e.g. B. trees, masts, Signs are automatically recognizable as "going" targets in a manner known per se and are therefore not evaluated for issuing a warning signal. * A higher than However, if the vehicle is approaching from behind at its own speed, it will be affected by reported to the measuring device of the warning system according to the invention, and if the value falls below a mutual vehicle distance dependent on the relative approach speed between the carrier vehicle and the same following vehicle the specified Warning signals are given. The distance measurement takes place in the case of the invention Warning system preferably by using and evaluating a frequency modulation the transmission signals of the reflection measuring device.
Die erfindungsgemäße Warnanlage hat den großen Vorteil, daß der Führer des von hinten auffahrenden Fahrzeugs durch das vorausfahrende Fahrzeug gewarnt wird, ohne daß er selbst das Instrumentenbrett seines eigenen Fahrzeugs beobachten muß; er erkennt die Gefahr, in die er sich durch zu große Annah'erung an das vorausfahrende Fahrzeug begibt, in seiner eigenen Blickrichtung, nämlich hinten am vorausfahrenden Fahrzeug an dessen Warnsignalgeber.The warning system according to the invention has the great advantage that the driver of the vehicle driving up from behind through the vehicle ahead being warned without even touching the instrument panel of his own vehicle must watch; he recognizes the danger in which he can become too close to the vehicle ahead, in its own viewing direction, namely at the rear of the vehicle in front on its warning signal generator.
Die Erfindung ist nicht auf die Verwendung im Straßenverkehr auf dem Lande beschränkt, sondern auch vorteilhaft zur Verkehrs sicherung auf anderen Verkehrswegearten, benutzbar beispielsweise im Binnenschiffahrtsverkehr.The invention is not intended for use on the road Land restricted, but also advantageous for traffic safety on other types of traffic routes, can be used, for example, in inland waterway traffic.
