Abstract

In an electronic unit (12) installed securely in the vehicle, a pluggable memory card (5) is locked mechanically so as to be withdrawable by authorised persons only. It has four memory blocks for time of day (1), road speed (2), and transverse and longitudinal accelerations (3,4) measured by separate accelerometers (10,11). A time-signal receiver (6) drives a clock pulse generator (7). All memories (1-4) are clocked synchronously and recordings are interrupted simultaneously when a standstill condition is detected (8). USE/ADVANTAGE - Esp. for accident investigations, all significant data are precisely timed and stored directly and separately in individual memories.

Description

Der Kurzwegschreiber (KWS) wird in einem Kraftfahrzeug eingebaut, und hat die Aufgaben, die Daten: Zeit, Geschwindigkeit, Quer- und Längs­ beschleunigungen einzulesen und zu speichern.The short path recorder (KWS) is installed in a motor vehicle, and has the tasks, the data: time, speed, lateral and longitudinal read in and save accelerations.

Da es nach kurzer Zeit immer wieder zur automatischen Löschung der Daten kommt, ist es eine Frage der Speicherkapazität und der Erfahr­ ungswerte, welche Zeitspanne zukünftig erforderlich ist. (z. B. 60 Sek.) Nach dem Stand der Technik gibt es Unfallschreiber, die Zeit - Geschwin­ digkeit - und Weg - Informationen nicht direkt aufzeichnen. Sie werden nach dem weit verbreiteten Verfahren der Koppel-Navigation, die auch in der Luft - Raum- und Schiffahrt üblich ist, ausgewertet.Since after a short time the automatic deletion of the When data comes, it's a question of storage capacity and experience values, which time period will be required in the future. (e.g. 60 seconds) According to the state of the art, there are accident recorders, the time - speed Do not record information directly and on the way. you will be according to the widespread method of paddock navigation, which too in the air - space and shipping is evaluated.

Die Erfindung hat sich die Aufgabe gestellt, alle Daten direkt und ge­ trennt in einzelnen Speichern zeitgleich einzulesen. Dies ist möglich, indem der KWS mit einem Zeitzeichen-Empfänger (6) ausgerüstet ist und die vom Sender DCF-77 ausgesandten Zeit-Informationen empfängt. Gleichzeitig mit dem weiteren Vorteil, daß bei einer Unfallaufzeich­ nung Sekunden - Minuten - Stunden und Datum exakt gespeichert sind. Ebenfalls synchron zu allen anderen Fahrzeugen, die auch einen KWS ein­ gebaut haben. Bei der Auswertung von Massenkarambolagen ist dies sehr wichtig.The invention has set itself the task of reading in all data directly and separately in individual memories at the same time. This is possible because the KWS is equipped with a time signal receiver ( 6 ) and receives the time information sent by the transmitter DCF-77. At the same time with the further advantage that seconds, minutes, hours and date are saved exactly in the event of an accident recording. Also in sync with all other vehicles that have built a KWS. This is very important when evaluating billiards.

Durch die getrennte und getaktete Datenspeicherung von Zeit (1), Ge­ schwindigkeit (2), Quer- (3) und Längsbeschleunigung (4) auf einer Speicherkarte (5) zusammengefaßt, ist es sehr einfach, die Daten am Monitor sichtbar zu machen. Ein Herausnehmen der Speicherkarte aus dem KWS ist nur von Befugten möglich. Durch die Nullkennung (8) wird der absolute Stillstand des Fahrzeugs erkannt und damit alle Datenspeicher­ ungen zeitgleich gestoppt. Die Löschsperre (9) wird bei einem Unfall aktiviert und verhindert, daß vorhergehende Daten nicht gelöscht, son­ dern noch durch die Daten des Unfalls ergänzt und erhalten bleiben. Bei einem Unfall genau in Fahrtrichtung liefern beide Sensoren (9) und (10) den gleichen Meßwert. Bei einer Differenz der Meßwerte lassen sich innerhalb der Daten-Speicherungszeit Überholvorgänge, Schlangenfahren, und Aufprall-Winkel beim Unfall registrieren.Due to the separate and clocked data storage of time ( 1 ), Ge speed ( 2 ), lateral ( 3 ) and longitudinal acceleration ( 4 ) summarized on a memory card ( 5 ), it is very easy to make the data visible on the monitor. Only authorized persons can remove the memory card from the KWS. The zero identification ( 8 ) detects the absolute standstill of the vehicle and thus all data storage is stopped at the same time. The deletion lock ( 9 ) is activated in the event of an accident and prevents previous data from being deleted, but supplemented and retained by the data from the accident. In the event of an accident exactly in the direction of travel, both sensors ( 9 ) and ( 10 ) deliver the same measured value. If there is a difference in the measured values, overtaking maneuvers, queuing, and impact angles in the event of an accident can be registered within the data storage time.
