Description

1. Problem1st problem

Seit Anfang des Jahres 2015 häufen sich Diebstähle von hochwertigen Pkw verschiedener Hersteller, die mit Keyless-Entry-Systemen oder Keyless-Go-Systemen ausgestattet sind. Die Fahrzeuge werden unter Zuhilfenahme von sogenannten Funkwellenverlängerern entwendet.Since the beginning of 2015, theft of high-quality cars from various manufacturers that are equipped with keyless entry systems or keyless go systems is increasing. The vehicles are stolen with the help of so-called radio wave extenders.

Diese Funkwellenverlängerer bestehen aus zwei Teilen, dem Car-Scanner und dem Key-Scanner. Während der Car-Scanner nahe an der Antenne, zumeist in Fahrertürnähe platziert wird, muss sich der Key-Scanner in der Nähe des Fahrzeugschlüssels befinden. Nach der Signalübertragung wird der Car-Scanner in den Pkw gelegt, so dass das Fahrzeug gestartet werden kann. Das Prinzip der Funkwellenverlängerer beruht auf der „Verlängerung” der Signale (Repeater-Funktion), die zwischen dem Fahrzeug und dem Fahrzeugschlüssel ausgetauscht werden. In der Praxis stellt sich das Vorgehen der Täter wie folgt dar: Ein Täter steht mit einem Car-Scanner in der Tasche am Fahrzeug und ein weiterer Täter mit einem Scanner in der Nähe der Haustür, da viele Autofahrer ihren Autoschlüssel in der Nähe der Haustür aufbewahren. Innerhalb kürzester Zeit wird das Fahrzeug geöffnet und gestohlen.These radio wave extenders consist of two parts, the car scanner and the key scanner. While the car scanner is placed close to the antenna, usually near the driver, the key scanner must be close to the vehicle key. After signal transmission, the car scanner is placed in the car so that the vehicle can be started. The principle of radio wave extenders is based on the "extension" of the signals (repeater function), which are exchanged between the vehicle and the vehicle key. In practice, the perpetrators act as follows: A perpetrator stands in the car's pocket with a car scanner and another offender with a scanner near the front door, as many drivers keep their car keys near the front door , Within a short time the vehicle is opened and stolen.

2. Lösung2nd solution

In den Funkschlüssel wird ein Bewegungsdetektor in Gestalt eines Beschleunigungssensors, Neigeschalters o. ä. integriert, der bei Bewegung des Funkschlüssels ein Zeitfenster von z. B. 3 Sekunden startet. Nur innerhalb dieses Zeitfensters wird das Aussenden des umcodierten Antwortsignals an das Fahrzeug gestattet.In the radio key, a motion detector in the form of an acceleration sensor, tilt switch o. Ä. Integrated, the movement of the radio key, a time window of z. B. 3 seconds starts. Only within this time window is it possible to send the transcoded response signal to the vehicle.

Somit kann ein Öffnen und Starten des Fahrzeugs nur dann erfolgen, wenn sich der Besitzer dieses Funkschlüssels dem Fahrzeug nähert.Thus, opening and starting of the vehicle can only take place when the owner of this remote key approaches the vehicle.
