Vehicle Theft Detection via Body Control Module Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle theft detection systems are vulnerable to disablement via disconnection or wireless jamming, which can prevent vehicle tracking during theft, highlighting a need for enhanced methods and systems to improve theft detection efficacy.
Innovation Solution
A method and system that integrates a telematics module, a body control module, and an engine control module within a vehicle, with communication to a remote backend server, detecting events that define a theft flag and activate specific theft-detection states such as inhibited propulsion, video recording, and component lockdown when the telematics module is disabled, and deactivating these states when the module is re-enabled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the telematics module is disabled via disconnection or wireless jamming, then the vehicle tracking function is compromised, but the system complexity and cost increase with multiple monitoring modules
Solution Approach 1:
The patent combines multiple monitoring functions into a unified system where the body control module serves as a central hub that coordinates between the telematics module, engine control module, and various vehicle subsystems. This integration allows the system to detect theft through multiple indicators (telematics disablement, engine runaway, alarm triggers) without requiring separate dedicated modules for each function, thereby improving reliability while controlling complexity.
Solution Approach 2:
The body control module is designed with multi-functionality, serving as both a monitoring center and an actuator for theft-detection states. It can detect various theft indicators, coordinate responses across different vehicle systems, and manage communication between modules. This universal approach allows a single module to perform multiple roles, reducing the need for additional specialized components.
2Reliability
If multiple monitoring modules are added to detect telematics disablement, then the theft detection reliability improves, but the device complexity and cost increase
Solution Approach 1:
The patent merges the monitoring functions of multiple potential modules into the existing body control module. Rather than adding separate dedicated monitoring modules, the body control module is enhanced to perform monitoring of telematics communication, engine status, alarm systems, and coordination of theft-detection responses. This consolidation maintains reliability through multiple detection points while avoiding the complexity of additional standalone modules.
3Reliability
If the system activates multiple theft-detection states rapidly when theft is detected, then the security effectiveness improves, but the energy consumption increases
Solution Approach 1:
The system pre-defines multiple theft-detection states and their corresponding responses in advance. When theft is detected, the body control module can rapidly activate pre-programmed responses such as disabling propulsion, locking components, or triggering alarms without requiring real-time decision-making for each action. This preliminary configuration enables rapid response while optimizing energy usage by activating only the necessary pre-planned responses.
4Reliability
If the system continuously monitors for telematics module status, then the theft detection capability improves, but the energy consumption and processing load increase
Solution Approach 1:
The body control module implements periodic monitoring of telematics module status and communication rather than continuous monitoring. The system checks for theft indicators at defined intervals, monitoring for events such as loss of communication with the telematics module, engine runaway conditions, or alarm triggers. This periodic approach maintains effective theft detection capability while significantly reducing energy consumption and processing load compared to continuous monitoring.
