Vehicle Signal Authentication Module for Non-Disruptive Anti-Theft Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle anti-theft systems often require disruptive methods that interfere with internal functions or are easily bypassed, failing to prevent theft and provide comprehensive authentication.
Innovation Solution
A signal-based authentication system that integrates into a vehicle's electromechanical systems, using a microprocessor to authenticate users and control vehicle functions without disrupting normal operation, allowing or altering signals based on authentication status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disruptive methods like short circuiting power supply are used to prevent theft, then security is improved, but the internal functions of the system are interfered with and damaged
Solution Approach 1:
The patent introduces an authentication system as an intermediary layer between the user and the vehicle's electro-mechanical systems. This authentication module intercepts and validates control signals (like ignition requests) before they reach the target systems, preventing unauthorized access without disrupting the normal operation of the vehicle's internal functions. The intermediary approach allows security checks to be performed seamlessly in the signal flow path.
2Reliability
If access control mechanisms are added to prevent unauthorized access, then security is improved, but the complexity of the system increases
Solution Approach 1:
The authentication system is designed to work universally with various electro-mechanical systems in the vehicle (ignition, steering, fuel injection, etc.) through a common signal interception approach. Rather than adding separate access control mechanisms for each system, the patent creates a single authentication module that can control multiple functions by intercepting their respective control signals, thereby reducing overall system complexity while maintaining comprehensive security.
3Reliability
If comprehensive authentication systems are integrated into electro-mechanical systems, then unauthorized usage is prevented, but maintenance and upgradability become difficult
Solution Approach 1:
The authentication functionality is extracted as a separate, standalone module that interfaces with the vehicle's existing electro-mechanical systems through signal interception. This modular design allows the authentication system to be removed, upgraded, or maintained independently without affecting the core vehicle systems. The separation enables easier repair and upgradability while maintaining comprehensive unauthorized usage prevention.
