Description

The invention relates to a method for operating a theft warning system of a motor vehicle. Furthermore, the invention relates to a theft warning system. Methods for operating a motor vehicle anti-theft alarm system, as well as motor vehicle anti-theft alarm systems themselves, are well known in the prior art. These systems are fundamentally designed to have a deterrent effect by triggering an alarm signal and informing the owner or the public of a potential break-in or theft attempt. Such an anti-theft alarm system necessarily incorporates vehicle sensors. To detect unintentional movement of the vehicle, at least one vibration sensor is required. However, this vibration sensor also detects movements, vibrations, or shocks resulting from intentional transport, such as on a ferry or car train. Often, direct access to the vehicle is not possible in these cases, meaning that a triggered alarm signal cannot be silenced immediately. In this context, it is important to note that... DE 10 2006 047 390 A1 It is known to compare sensor signals from different sensor types to rule out false alarms. JP 2006 69362 A In contrast, one theft warning system uses a navigation system to determine whether the vehicle is on an authorized transport vehicle. While both approaches reduce the number of false alarms, their design means they cannot account for all transport situations. Therefore, the object of the invention is to provide a method for operating a theft warning system of a motor vehicle and a theft warning system that avoid the aforementioned disadvantage in a simple and cost-effective manner. This problem is solved according to the invention by determining a vehicle's position using a GPS module and transmitting vehicle position data to a control unit. Vehicle sensors detect changes in the vehicle's position, vibration, and/or shock, and transmit the resulting vehicle movement data to a control unit. Subsequently, the vehicle position data is compared with the vehicle movement data, and a probability profile is created for the expected movement that would trigger a position-dependent alarm signal. Then, either a position-independent alarm signal is triggered by an alarm system in the case of a low probability, or a check of the vehicle's immediate vicinity is performed in the case of a high probability, in order to then trigger the alarm signal by the alarm system in the immediate vicinity. This ensures high reliability. Finally, break-ins can also occur on intended transport routes, which in this case must be reliably detected. By transmitting the vehicle position data as raw data from the GPS module to an analysis unit, the control unit then uses GPS analysis to transmit processed vehicle position data. This allows the vehicle position data to be easily overlaid with images, which can then be verified in the next step. For this purpose, the control unit compares the processed vehicle position data with image data of the vehicle's surroundings. The problem is also solved by an anti-theft warning system for operating such a method, wherein the anti-theft warning system comprises at least a GPS module, a control unit, at least one vehicle camera, vehicle sensors with at least one vibration, acceleration, or tilt sensor, and at least one alarm signaling system. Advantageously, the alarm signaling system can be designed as a vehicle signaling system. A second analysis unit for classifying image data from the vehicle camera is particularly advantageous. This allows raw data from the GPS module to be processed quickly and easily. The first and/or second analysis unit can be self-learning, for example, using AI. Furthermore, a second analysis unit for classifying image data from the vehicle camera can be advantageously provided. The control unit advantageously includes a decision algorithm for calculating the probability profile. An embodiment of the invention is explained in more detail with reference to the drawing. The single figure shows in schematic form a method according to the invention for operating a theft warning system 2. In the present embodiment, the theft warning system 2 comprises a GPS module 4, a control unit 6, a vehicle camera 8, and vehicle sensors 10 with various sensors not shown. The system includes sensors such as vibration, acceleration, or tilt sensors. The anti-theft alarm system also features an alarm signaling system 12 in the form of a vehicle signaling system. However, additional alarm signaling systems, such as headlights or a key fob, can also be included. It is also possible to send a push notification or a call to a mobile device. This can be done directly via a phone contact or an app. Furthermore, a first analysis unit 14 is provided for processing vehicle position data with stored image data, and a second analysis unit 16 is provided for classifying image data from the vehicle camera 8. Both analysis units 14 and 16 are self-learning, with a standard pre-training program upon which the
