Abstract

The audible and/or visual alarm which may also inhibit starting of the engine is connected to an air compressor responsible for adjustment of tyre pressures, e.g. in accordance with road speed. Forced entry into the vehicle triggers the alarm and causes total deflation of one or more tyres, making it difficult to drive away. At a predetermined low value of tyre pressure, the regulator is immobilised so that immediate reflation is prevented effectively. ADVANTAGE - Pressure in deflated tyre(s) cannot be restored until theft alarm has been reset.

Description

Die Erfindung betrifft eine Sicherheitseinrichtung für Kraftfahrzeuge nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a safety device for Motor vehicles according to the preamble of the claim 1.

Es ist bekannt, Kraftfahrzeuge mit einer Diebstahlwarnanlage auszustatten. Ferner ist es bekannt, Kraftfahrzeuge mit einer Reifenluftdruck-Regelvorrichtung auszustatten, die eine fahrzeugeigene Luftdruckquelle, beispielsweise einen Kompressor, aufweist und mit der der Reifenluftdruck auch während der Fahrt beispielsweise in Abhängigkeit von der Fahrgeschwindigkeit geregelt werden kann.It is known to use a motor vehicle Anti-theft alarm system. It is also known Motor vehicles with a tire air pressure control device to equip a vehicle's own air pressure source, for example, a compressor, and with which Tire air pressure even while driving, for example in Depending on the driving speed can be regulated can.

Der Erfindung liegt die Aufgabe zugrunde, eine Sicherheitseinrichtung für Kraftfahrzeuge, die sowohl mit einer Diebstahlwarnanlage als auch mit einer Reifenluftdruck-Regelvorrichtung ausgestattet sind, besonders zweckmäßig auszubilden.The invention has for its object a Safety device for motor vehicles, both with an anti-theft alarm system as well as with a Tire air pressure control device are equipped training particularly useful.

Die Lösung dieser Aufgabe ist in dem kennzeichnenden Teil des Patentanspruchs 1 angegeben. Durch sie wird erreicht, daß neben den bekannten Maßnahmen, die im Alarmfall ausgelöst werden, beispielsweise akustische und/oder optische Warnsignale, Verhinderung des Startens des Fahrzeugantriebmotors, eine zusätzliche Maßnahme ergriffen wird, die ein Wegfahren des Fahrzeugs erschwert. Durch das Blockieren der Reifenluftdruck- Regelvorrichtung wird verhindert, daß der Reifenluftdruck während des Alarmfalls mit fahrzeugeigenen Mitteln angehoben werden kann.The solution to this problem is in the characterizing part of claim 1 specified. Through it is achieved that in addition to the known measures in the event of an alarm are triggered, for example acoustic and / or optical warning signals, prevention of starting the Vehicle drive motor, an additional measure is taken, the driving away of the vehicle  difficult. By blocking the tire air pressure Control device prevents the tire air pressure during the alarm with the vehicle's own means can be raised.

Es ist besonders zweckmäßig, den Reifenluftdruck bis auf den Atmosphärendruck abzusenken, also die Reifendruckluft völlig abzulassen.It is particularly useful to set the tire air pressure down to to lower the atmospheric pressure, i.e. the tire compressed air draining completely.

Außerdem ist es besonders zweckmäßig, die Druckabsenkung an allen Fahrzeugrädern vorzusehen. Jedoch kann ein Effekt in der gewünschten Richtung auch schon dadurch erzielt werden, daß die Druckabsenkung nur an einer Fahrzeugachse erfolgt.It is also particularly useful to reduce the pressure to be provided on all vehicle wheels. However, one Effect in the desired direction achieved that the pressure drop at only one Vehicle axis takes place.

Nach Beendigung des Alarmfalles ist die Blockierung der Reifenluftdruck-Regelvorrichtung aufzuheben. Dies kann mit der Bedienung der Diebstahlwarnanlage gekoppelt werden, so daß bei deren Rücksetzung die Reifen wieder aufgepumpt werden und anschließend die Reifenluftdruck- Regelvorrichtung wieder normal arbeitet.After the alarm case has ended, the Remove the tire air pressure control device. This can coupled with the operation of the anti-theft alarm system so that when you reset the tires again be inflated and then the tire pressure Control device works normally again.
