Distributed Vehicle Anti-Theft Network Using Sensor Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for preventing motor vehicle thefts, such as cloning keys or using GSM scramblers, are ineffective as they can be manipulated or disabled, leading to a need for reliable anti-theft measures.
Innovation Solution
A method where a monitored motor vehicle forms a group with nearby vehicles to share sensing technology, using query data records and sensor data to detect irregularities and generate alarms, ensuring continuous anti-theft protection by verifying the identity of the driver and monitoring the vehicle's surroundings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motor vehicle uses individual anti-theft measures (such as cloning keys or GSM scramblers), then the vehicle can be protected against theft, but the protection can be manipulated or disabled by thieves
Solution Approach 1:
The patent merges multiple individual anti-theft systems into a collective monitoring network where multiple vehicles share sensing resources. Instead of each vehicle having complete anti-theft capabilities, vehicles combine their sensors to form a distributed surveillance system that is more reliable and harder to manipulate than individual systems.
Solution Approach 2:
The sensing technology originally designed for individual vehicle monitoring is made universal by allowing it to serve multiple vehicles. The sensors in neighboring vehicles perform anti-theft monitoring for the monitored vehicle in addition to their primary functions, creating multi-functional use of existing hardware.
2Reliability
If a motor vehicle uses GSM scramblers to prevent tracking, then position-fixing is prevented, but the scramblers can be detected and bypassed by thieves
Solution Approach 1:
The patent introduces intermediary sensing systems in neighboring vehicles that indirectly monitor the vehicle's status and surroundings. Instead of relying on direct monitoring that can be bypassed, the intermediary sensors detect irregularities such as unauthorized opening attempts or movement, providing indirect but more difficult to bypass surveillance.
Solution Approach 2:
The system performs preliminary detection of theft attempts by monitoring for irregularities before actual theft occurs. The neighboring vehicles detect suspicious activities such as unauthorized access attempts or abnormal movements and can trigger alerts before the vehicle is stolen.
3Reliability
If a motor vehicle implements comprehensive individual monitoring systems, then theft prevention is improved, but energy consumption and system complexity increase
Solution Approach 1:
Instead of every vehicle implementing full monitoring capabilities, the patent uses partial action where only neighboring vehicles perform monitoring for a given vehicle. This distributed approach reduces the energy burden on each individual vehicle while maintaining comprehensive surveillance through the collective effort of multiple vehicles.
Solution Approach 2:
The system uses the existing sensing capabilities of neighboring vehicles for mutual benefit. Each vehicle's sensors serve not only its own monitoring needs but also contribute to the security of neighboring vehicles, creating a self-service network where resources are shared and energy consumption is optimized through cooperation.
Data Source
AI summary
The disclosure relates to a method for preventing thefts of motor vehicles. The method includes detecting motor vehicles within a predetermined neighborhood of a motor vehicle to be monitored. The method further includes sending a query data record from the motor vehicle to be monitored to the detected motor vehicles. The method also includes monitoring of the motor vehicle to be monitored by the detected motor vehicles on reception of the query data record.
