AI Technical Summary
Conventional vehicle monitoring systems fail to accurately detect unauthorized towing due to their reliance on cloud-dependent architectures and lack of mechanisms tailored for gradual tilt and acceleration patterns, leading to latency and privacy concerns.
An autonomous warning device integrating an accelerometer and processor to analyze tilt and acceleration, with a GSM module for direct SMS alerts, operates independently of centralized servers to enhance detection accuracy and privacy.
The device provides precise towing detection with reduced latency and improved privacy by using autonomous sensors and direct communication, reducing false alarms and infrastructure dependency.

Abstract
Description
AREA
[0001] The present disclosure relates generally to a warning device for detecting the unauthorized towing of a vehicle using autonomous sensor and communication modules. GENERAL STATE OF THE ART
[0002] Conventional vehicle monitoring and warning systems typically use accelerometers, gyroscopes, GPS modules, and GSM communication interfaces to detect changes in movement, orientation, and location, and to send alerts to users. Such systems are commonly used for theft prevention, accident detection, navigation, and fleet management, and often rely on centralized servers or cloud platforms for data processing and notification delivery. However, these architectures result in latency, infrastructure dependency, and privacy concerns. Furthermore, existing systems are not specifically designed to detect unauthorized towing, which is characterized by gradual changes in tilt combined with distinctive acceleration patterns.As a result, conventional solutions lack precise, autonomous detection mechanisms tailored to towing scenarios, particularly in urban environments where unauthorized towing of vehicles is common. SUMMARY
[0003] The subject matter of the present invention is defined in the claims. BRIEF DESCRIPTION OF THE FIGURES Fig. Figure 1 illustrates a warning device for detecting the unauthorized towing of a vehicle using autonomous sensor and communication modules. DETAILED DESCRIPTION OF THE INVENTION
[0004] Unauthorized vehicle towing remains a persistent problem in urban areas, where parked vehicles are removed without the owner's knowledge. Conventional vehicle monitoring systems are based on cloud-dependent architectures and are primarily designed for theft or accident detection. They are unable to accurately identify towing operations, which are characterized by gradual changes in tilt and distinct acceleration patterns.
[0005] The present disclosure addresses the problem of unauthorized towing by providing an autonomous warning device specifically configured to detect towing-related vehicle movements. The device integrates an accelerometer configured to measure the vehicle's tilt angle and a processor configured to analyze the tilt angle in conjunction with the vehicle's acceleration to accurately determine towing activity. By correlating changes in tilt with acceleration thresholds, the processor distinguishes towing events from normal driving or parking conditions, thereby improving detection accuracy and reducing false alarms.A GSM communication module, operationally connected to a SIM card, is configured to send SMS notifications directly to the user's mobile device upon detecting towing activity. This direct communication architecture eliminates reliance on centralized servers or cloud platforms, ensuring immediate alarm transmission, reduced latency, improved reliability, and enhanced user privacy. The device is housed in a compact enclosure suitable for installation on two- and four-wheeled vehicles without any structural modifications. Tamper protection can be integrated to trigger an additional alarm if the device is removed without authorization.The accelerometer can be implemented as a three-axis sensor to detect lateral and longitudinal tilt angles, and the processor can execute intelligent algorithms to filter out transient tilt fluctuations. Optional features such as GPS integration, visual displays, and support for mobile applications further enhance usability. Through autonomous operation and modular integration as defined in the claims, the invention provides a precise, reliable, and user-friendly solution for detecting unauthorized towing.
[0006] Fig.Figure 1 shows a block diagram of a warning device 100 configured to detect the unauthorized towing of a vehicle. The system includes an accelerometer 102, which measures the vehicle's tilt angle; a processor 104, which analyzes the tilt angle in conjunction with the vehicle's acceleration to determine towing activity; and a GSM communication module 106, which is coupled to the processor 104 and functionally connected to a SIM card. The GSM communication module 106 is configured to send an SMS notification to the user's mobile device when towing activity is detected. The alarm device 100 is further configured to operate autonomously 108 without dependence on an external server, thus ensuring independent functionality.Each module is represented as a separate block connected to the central alarm unit 100, with the reference numbers clearly indicating its functions. The diagram visually illustrates the internal architecture and the logical data flow between the components for acquisition, processing, communication, and autonomous operation.
[0007] Although the implementations of the device for detecting the unauthorized towing of a vehicle and the system for detecting this process have been described with respect to certain structural features and functional modules, it should be noted that the appended claims are not limited to the disclosed particular embodiments. The described features and modules serve for illustration purposes, and variations, modifications, or equivalent arrangements that are compatible with the principles of the present invention may be implemented without derogation from the scope of the claims.
