Abstract

The strain-gauges are positioned in the steering-wheel lock, in the steering itself and in the door locks. Any attempt to force the operation of these controls operates a cut-out switch hidden in the electrics to isolate the battery (3). The security system incorporates security electronics it (5) which immobilise the operation of the vehicle, block the transmission and operate alarms. ADVANTAGE - Improved protection; uses sensors similar to impact sensors.

Description

Die Erfindung bezieht sich auf eine Kfz-Diebstahlsicherung, die aus zwei logischen Blöcken besteht; der Diebstahlerkennung und der Diebstahlverhinderung.The invention relates to a vehicle anti-theft device, which consists of two logical blocks consists; theft detection and theft prevention.

DiebstahlerkennungTheft detection

Ein oder mehrere Sensoren, die auf mechanische Spannungen im Metall ansprechen, werden von außen nicht zugänglich am Lenkradschloß oder in dessen Nähe angebracht. Wird das Lenkradschloß gewaltsam aufgebrochen, erkennt dieser Sensor die Erschütterung, die Verformung oder den Bruch an Lenkradschloß oder Lenksäule.One or more sensors that respond to mechanical stresses in the metal are used by not accessible from the outside on the steering wheel lock or in the vicinity. The steering wheel lock broken open by force, this sensor detects the shock, deformation or breakage on the steering wheel lock or steering column.

Der Sensor arbeitet nach einem ähnlichen der gleichen Prinzip wie die Sensorik des Airbags. Hierfür können handelsübliche Sensoren verwendet werden.The sensor works on a similar principle to that of the airbag sensors. Standard sensors can be used for this.

Der Sensor kann auch im Zünd- oder Türschloß angebracht werden um einen gewaltsamen Aufbruch zu erkennen.The sensor can also be installed in the ignition or door lock to prevent violent Recognizing departure.

Stand der TechnikState of the art

Den Erfindern sind keine diebstahlerkennenden Mechanismen an Lenkrad- oder Zündschlössern bekannt.The inventors are not aware of theft-detecting mechanisms on steering wheel or ignition locks known.

DiebstahlverhinderungTheft prevention

Das Signal des Sensors kann nun folgende Mechanismen in Gang setzen:The signal from the sensor can now initiate the following mechanisms:

Die gesamte Stromversorgung oder die für die Bewegung des Kfz wichtigen Teile werden abgeschaltet.The entire power supply or the parts that are important for the movement of the motor vehicle switched off.

Dies kann durch ein Unterbrechungsglied, in dem das vom Sensor kommende Signal erkannt wird, geschehen.This can be done by an interruption element in which the signal coming from the sensor is recognized, happen.

Fig. 1 stellt eine solche Schaltung schematisch dar. Ein solches Unterbrechungsglied ist einbruchsicher im Motorraum oder im Fahrzeuginneren einzubauen. Im einfachsten Fall wird es durch ein Relais, das über eine Transistorstufe geschaltet wird realisiert. Fig. 1 shows such a circuit schematically. Such an interruption element is burglar-proof to install in the engine compartment or inside the vehicle. In the simplest case, it is implemented by a relay that is switched via a transistor stage.

Ferner können durch das Sensorsignal Mechanismen zur Blockierung von Getriebe und Bremsen, Hup- und Lichtsignale ausgelöst werden.Mechanisms for blocking gears and brakes, Horn and light signals are triggered.

Vorteile der ErfindungAdvantages of the invention

Eine Entwendung des Kfz ist durch bloßen Aufbruch des Lenkrad- und Zündschlosses nicht mehr möglich. Ein Einbruch wird bemerkt und das Kfz fahrunfähig gemacht. Eine Aufhebung dieses Zustands ist dann nur durch geschultes Fachpersonal (z. B. Vertragshändler des Kfz-Herstellers möglich).Theft of the vehicle is no longer simply a matter of breaking the steering wheel and ignition lock possible. A break-in is noticed and the motor vehicle is disabled. Repeal this The condition is then only by trained specialist personnel (e.g. authorized dealer of the vehicle manufacturer possible).

Claims (6)

1. Diebstahlerkennung durch einen oder mehrere Sensoren, die auf mechanische Spannungen ansprechen und am Lenkradschloß oder in dessen Nähe angebracht sind. Wird das Lenkradschloß gewaltsam aufgebrochen, erkennt dieser Sensor die Erschütterung, die Verformung oder den Bruch an Lenkradschloß oder Lenksäule.1. Theft detection by one or more sensors that detect mechanical stresses respond and are attached to or in the vicinity of the steering wheel lock. The steering wheel lock broken open by force, this sensor detects the shock, deformation or breakage on the steering wheel lock or steering column. Der Sensor arbeitet nach einem ähnlichen oder gleichen Prinzip wie die Sensorik des Airbags. Hierfür können handelsübliche Sensoren verwendet werden.The sensor works on a similar or the same principle as the sensor system of the airbag. Standard sensors can be used for this. 2. Der Sensor kann im Zündschloß oder dessen Nähe angebracht werden, um einen gewaltsamen Aufbruch des Schlosses zu erkennen.2. The sensor can be placed in the ignition lock or its vicinity to detect a violent Recognize the opening of the castle. 3. Der Sensor kann im Türschloß oder dessen Nähe angebracht werden, um einen gewaltsamen Aufbruch des Schlosses zu erkennen.3. The sensor can be installed in the door lock or its vicinity to prevent violent Recognize the opening of the castle. 4. Der Sensor kann an jeden Teil des Kfz angebracht werden der bei einem Aufbruch des Kfz mechanischen Spannungen ausgesetzt ist.4. The sensor can be attached to any part of the car that breaks open when the car is exposed to mechanical stresses. 5. Das im Falle eines Aufbruchs vom Sensor kommende Signal wird von einer elektronischen Schaltung erkannt und löst diebstahlverhindernde Mechanismen aus.5. The signal coming from the sensor in the event of a break is sent by an electronic Circuit detected and released anti-theft mechanisms out.
