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 patent claim 1.

Bei einer aus der DE 37 18 471 A1 bekannten Sicherheitseinrichtung dieser Art ist in den Reifen des Kraftfahrzeugs ein kugelförmiger Meßfühler frei beweglich angeordnet, der Angaben über den Reifendruck, die Reifentemperatur und die Meßfühler-Eigenbewegung liefern kann, von denen die Angaben über die Eigenbewegung des Meßfühlers zur Diebstahlsicherung des Kraftfahrzeugs herangezogen werden. Eigenbewegungen des Meßfühlers können sich nur bei Fahrbewegungen des Kraftfahrzeugs ergeben. Die Angaben über den Reifendruck sollen es ermöglichen, das Gewicht der Zuladung zu überwachen, und können ebenfalls die Diebstahlwarnanlage auslösen. In a safety device known from DE 37 18 471 A1 this type is in the tires of the motor vehicle a spherical probe is freely movable, the Information about the tire pressure, the tire temperature and the Sensor self-movement can provide, of which the information about the own movement of the sensor for theft protection of the motor vehicle are used. Own movements the sensor can only move when the Motor vehicle result. The information about the tire pressure should make it possible to monitor the weight of the load, and can also trigger the anti-theft alarm system.  

Aus der US 30 03 539 ist eine Diebstahlsicherung für Kraftfahrzeuge bekannt, bei der durch eine an dem Reifenventil angeordnete Reifenluftdruck-Absenkvorrichtung der Reifenluftdruck auf den Atmosphärendruck abgesenkt werden kann, wenn bei einer Radrotation ein Zentrifugalgewicht der Einrichtung ausgelenkt wird. Die Einrichtung kann ein- und ausgeschaltet werden. Bei ausgeschalteter Einrichtung ist ein unbehinderter Fahrbetrieb des Kraftfahrzeugs möglich. Bei eingeschalteter Einrichtung erfolgt hingegen die Druckabsenkung sowohl bei unbefugter Benutzung des Fahrzeugs als auch bei befugter Benutzung des Fahrzeugs, wenn beispielsweise vergessen wurde, die Absenkvorrichtung auszuschalten. Die Diebstahlsicherung wird nur bei Fahrbewegungen des Fahrzeuges wirksam, bei denen sich eine für die Auslenkung des Zentrifugalgewichts ausreichend hohe Raddrehzahl ergibt.From US 30 03 539 is an anti-theft device for Motor vehicles are known in which by on the tire valve arranged tire air pressure lowering device of the Tire air pressure can be reduced to atmospheric pressure can, if a centrifugal weight of the Facility is deflected. The facility can one and turned off. When the device is switched off unrestricted driving of the motor vehicle is possible. On the other hand, when the device is switched on Pressure reduction both when the vehicle is used without authorization as well as with authorized use of the vehicle if For example, it was forgotten to switch off the lowering device. The anti-theft device is only used when driving of the vehicle effective, in which there is one for the Deflection of the centrifugal weight sufficiently high wheel speed results.

Es ist auch bekannt, Kraftfahrzeuge mit einer Reifenluftdruck-Regelvorrichtung auszustatten, die eine fahrzeugeigene Druckluftquelle, beispielsweise einen Kompressor, aufweist und mit der der Reifenluftdruck auch während der Fahrt beispielsweise in Abhängigkeit von der Fahrgeschwindigkeit geregelt werden kann.It is also known to motor vehicles with a tire air pressure control device equip a vehicle's own Compressed air source, for example a compressor and with which the tire air pressure also during the Driving, for example, depending on the driving speed can be regulated.

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 to train particularly expediently.

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 Fahrrzeugs 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 triggered in the event of an alarm be, for example acoustic and / or optical Warning signals, preventing the vehicle drive motor from starting, an additional measure is taken that a Driving away 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.
