Abstract

The anti-theft system is combined with the onboard signal computer (2) linked to each of the vehicle electrical units, e.g. the engine operating control (3), the ignition coil (4), the starter motor (5) and the fuel pump (6), the computer only being activated upon scanning the correct code provided by a coding zone or code card incorporated in the vehicle ignition key. Pref. the signal computer only operates with a specific vehicle chassis number, to prevent it being changed, the electronic signal circuit using contact switches enclosed in a permanently sealed housing. USE - For preventing driving away of commercial vehicles unless authorised ignition key is inserted.

Description

Die Erfindung ist ein Diebstahlsicherungssystem für PKW und ähnliche Fahrzeuge.The invention is an anti-theft system for cars and similar vehicles.

Zusatz 2 zu Patent Nr. P 41 30 028.9Addition 2 to Patent No. P 41 30 028.9

Hier soll eine neue Aufgabenlösung aufgeführt werden.A new task solution is to be listed here.

Die Aufgabe wird wie folgt gelöst:The task is solved as follows:

Der Fahrzeugschlüssel hat auch hier einen Codierungs­ bereich, der mit dem Signalcomputer verbunden ist. Der Signalcomputer arbeitet nur durch Aktivierung mit dem Codierungsbereich. Erst dann gibt der Signalcomputer Spannungssignale an die entsprechenden Fahrzeugelemente, z. B. Zündspule, Anlasser usw.The vehicle key also has a coding here area connected to the signal computer. Of the Signal computer works only by activation with the Coding range. Then the signal computer gives Voltage signals to the corresponding vehicle elements, e.g. B. ignition coil, starter, etc.

Die Spannungszuführung von der Batterie erfolgt z. B. über eine Kontaktbrücke, die Signalelektronik steuert auf "ZU". Die dazu erforderlichen Bauteile sind in einem geschlossenen Gehäuse eingesetzt.The voltage supply from the battery takes place, for. B. about a contact bridge, the signal electronics control "CLOSE". The components required for this are enclosed Housing used.

Die daraus resultierenden Vorteile sind folgende:The resulting benefits are as follows:

Z.B. die Zündspule und der Anlasser bekommen Spannung von der Batterie, ein Kurzschließen ist nicht möglich. Der Signalcomputer muß die Spannungszuführung mittels einer Kontaktbrücke über die Signalelektronik einleiten.E.g. the ignition coil and the starter get voltage from the battery, a short circuit is not possible. The signal computer must use the power supply initiate a contact bridge over the signal electronics.

Ein Funktionieren der elektrischen Fahrzeugelemente ist nur durch die Spannungssignal-Abgabe vom Signalcomputer möglich und das wiederum erfordert ein Aktivieren durch Codierungsbereich (Zündschlüssel oder Karte). Ein Mani­ pulieren von außen ist somit ausgeschlossen. The electrical vehicle elements are functioning only by the voltage signal output from the signal computer possible and this in turn requires activation by Coding area (ignition key or card). A mani pulverizing from the outside is therefore excluded.
