Vehicle Speed Verification via V2V Reference Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for verifying a vehicle's speed are costly and unreliable, often requiring two separate sensor systems, which can lead to incorrect speed indications that may cause damage to the power train and allow for potential manipulation of driving and rest times.
Innovation Solution
A method and system utilizing vehicle-to-vehicle (V2V) or vehicle-to-infrastructure (V2I) communication to verify a vehicle's speed by comparing its speed data with that of nearby vehicles or infrastructure, eliminating the need for dual sensor systems and allowing for real-time correction and logging of speed errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two separate sensor systems are used to verify vehicle speed, then speed verification accuracy is improved, but system cost and complexity increase
Solution Approach 1:
The patent uses other vehicles as intermediary reference objects to verify speed. Instead of installing dual sensor systems in one vehicle, the system communicates with nearby vehicles via V2V communication to obtain their speed data, which serves as a reference to verify the own vehicle's speed measurements, thereby avoiding the need for duplicate sensors while achieving verification accuracy
Solution Approach 2:
The patent makes the vehicle communication system multi-functional by using it for both normal vehicle operations and speed verification. The V2V communication infrastructure, originally designed for general vehicle-to-vehicle interaction, is also utilized for cross-verification of speed data, eliminating the need for dedicated verification hardware and reducing overall system complexity
2Measurement precision
If two separate sensor systems are used to verify vehicle speed, then speed verification accuracy is improved, but cost increases
Solution Approach 1:
The system uses existing V2V communication capabilities and standard sensors already present in modern vehicles to perform speed verification. By leveraging the vehicle's own communication infrastructure and data from other vehicles, the patent eliminates the need for additional expensive verification hardware, making the solution cost-effective while maintaining accuracy
Solution Approach 2:
Instead of physically duplicating sensor systems, the patent creates a virtual copy of speed measurement data by obtaining speed information from other vehicles through communication networks. This informational copying allows verification without the physical duplication of expensive sensor hardware, significantly reducing system cost
3Ease of manufacture
If V2V communication is used for speed verification, then system cost is reduced, but communication reliability requirements increase
Solution Approach 1:
The system continuously exchanges speed data with multiple surrounding vehicles through V2V communication, creating a feedback mechanism where speed measurements are constantly verified against reference values from other vehicles. This continuous feedback allows the system to detect and correct measurement errors in real-time, compensating for potential communication reliability issues through multiple data sources and ongoing verification
Solution Approach 2:
The patent uses speed data from multiple surrounding vehicles rather than relying on a single reference vehicle. By gathering excessive reference data from several vehicles and performing verification based on the collective information, the system increases reliability through redundancy, ensuring that communication failures or errors in individual vehicle data do not compromise the verification accuracy
