`Abstract of WO 9418645 (A1)
`in order to record accidents caused to parked vehicles, for example by other cars, the invention
`provides that an accident data memory installed in the parked vehicle is extended by means which,
`preferably after a certain time—|ag after switching off the engine, maintain the accident data memory of
`the vehicle operative for a limited time with a sensitivity which is greater than that prevailing when the
`vehicle engine is switched on, in constant readiness for the detection and recording of an accident
`situation.

`
`(54) Title: ACCIDENT DATA MEMORY
`
`(54) Bezeichnung: UNFALl..DA'I'ENSPEICI-IE1
`
`(57) Abstract
`
`In order to record accidents caused to parked vehicles, for example by other cars, the invention provides that an accident data memory
`installed in the parked vehicle is extended by means which, preferably after a certain time-lag after switching off the engine, maintain the
`accident data memory of the vehicle operative for a limited time with a sensitivity which is greater than that prevailing when the vehicle
`engine is switched on, in constant readiness for the detection and recording of an accident situation.

`
`Unfalldatenspeicher
`
`Die Erfindung betrifft einen Unfalldatenspeicher gemafi dem
`
`Oberbegriff des Anspruchs l. Unfalldatenspeicher sind in ihrem
`Aufbau als solche bekannt.
`
`Der Zweck eines Unfalldatenspeichers besteht in der Erfassung
`
`und Registrierung Von Daten, die ffir die objektive Klérung der
`
`Schuldfrage nach einem Unfallereignis sachdienlich'sind. Es ist
`
`Stand der Technik, die Bewegungsdaten sowie die Zustandsdaten
`
`einiger Fahrzeugaggregate wéhrend des Fahrbetriebs des mit
`
`einem Unfalldatenspeicher ausgerfisteten Fahrzeugs zu
`
`registrieren.
`
`Im Unfalldatenspeicher geméfi der EP 0 118 818 B1
`
`endet die Datenaufzeichnung mit dem Fahrzeugstillstand.
`
`Die Detektion eines Unfallereignisses erfolgt fiblicherweise
`
`zumindest durch eine Auswertung der vom Unfalldatenspeicher
`
`erfafiten Beschleunigungssignale. Da Strafienunebenheiten, die
`
`normale Fahrdynamik oder das Zuschlagen einer Fahrzeugtfir nicht
`
`zur Auslésung der speziell ffir eine Unfallsituation
`
`vorgesehenen Speicherverfahren ffihren dfirfen, weisen die
`
`bekannten Unfalldatenspeicher Auslésekriterien auf, die die
`
`Registrierung von kleineren "Rempeleien" nicht gestatten. Wird
`
`ein parkendes Fahrzeug zB bei dem Rangiermanaver eines
`
`Fremdfahrzeugs angefahren, kann ein derartiger Unfall von den
`
`bisher bekannten Unfalldatenspeichern nicht registriert werden.
`
`Die Aufgabe der vorliegenden Erfindung ist es, diesen Nachteil
`zu beseitigen. Sie wird durch die kennzeichnenden Merkmale des
`
`ersten Anspruchs gelbst. Die weiteren Ansprfiche zeigen
`
`I‘.
`
`vorteilhafte Weiterbildungen.
`
`Erfindungsgemafi wird vorgeschlagen, zusétzlich zu den wéhrend
`
`des Fahrbetriebs erforderlichen héheren Ansprechschwellen ffir
`
`die Auslbsung der speziell zur unlbschbaren Registrierung einer
`
`Unfallsituation vorgesehenen Speicherverfahren Mittel
`
`Page 002153
`
`

`
`WO 94/13645
`
`.
`
`PCT/EP94/00152
`
`vorzusehen, die die Betriebsbereitschaft des
`
`Unfalldatenspeichers nach dem Ausschalten des Antriebsaggregats
`
`des Fahrzeugs fur eine begrenzte Zeit mit einer erhfihten
`
`Empfindlichkeit ffir die Detektion und Registrierung Von
`
`Unfallereignissen fortzusetzen.
`
`Die Erhéhung der Empfindlichkeit kann dadurch erfolgen, dafi der
`
`zur Auslésung der Unfallregistrierung festgesetzte Schwellwert
`
`der Amplitude der Beschleunigungssignale um etwa 90 %
`
`herabgesetzt wird bei gleichzeitiger Verléngerung des
`
`Betrachtungszeitraums der zur Auslésung ffihrenden
`
`Einwirkungsdauer des Beschleunigungssignals. Dadurch, dafi der
`
`Unfalldatenspeicher mit Mitteln zur Durchffihrung dieser
`
`Mafinahme erweitert wird, werden am geparkten Fahrzeug auch
`leichte Stdfie detektierbar.
`
`Um Fehlauslbsungen zu vermeiden, ist eine Umschaltung des
`
`Unfalldatenspeichers auf diese erhéhte Empfindlichkeit nur bei
`
`stillstehendem Fahrzeug sinnvoll. Zur Steuerung der Umschaltung
`
`benétigt der Unfalldatenspeicher die Information darfiber,
`
`in
`
`welchem Betriebszustand sich das Antriebsaggregat des Fahrzeugs
`
`befindet. Diese Abfrage erfolgt Vorzugsweise fiber eine
`
`Erfassung der Schaltstellung des Zfindstartschalters des
`
`Fahrzeugs.
`
`Um Fehlauslbsungen unmittelbar nach dem Ausschalten des
`
`Antriebsaggregats des Fahrzeugs zu vermeiden, die
`
`beispielsweise durch das Verlassen des Fahrzeugs durch die
`
`Fahrzeuginsassen oder das Entladen des Fahrzeugs hervorgerufen
`
`werden kénnten, empfiehlt es sich, die Umschaltung auf die
`
`erhéhte Empfindlichkeit zeitverzbgert durchzuffihren. Eine
`
`Verzégerung Von ca.
`
`5 Minuten erscheint im allgemeinen
`
`praxisgerecht. Dadurch kann sichergestellt werden, dafi sich das
`
`Fahrzeug in Ruhe befindet.
`
`Um ermittlungsdienliche Aussagen zum Unfallereignis machen zu
`
`kannen, ist es vorteilhaft, den erfindungsgeméfi erweiterten
`
`Unfalldatenspeicher mit Zeitzéhlmitteln auszustatten, so dafi
`
`der Unfallzeitpunkt genau bestimmt werden kann. Die

`
`ausgebildeten Echtzeituhr oder nur aus einem Relativzeitmesser
`
`bestehen.
`
`In jedem Fall kann auf diese Weise zusétzlich zu den
`
`durch die Beschleunigungssignale erfafiten Stofidaten eine
`
`Zeitmarke in dem registrierten Datensatz abgelegt werden.
