Vehicle Identification via Image and Inter-Vehicle Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle management systems face challenges in accurately determining a vehicle's travel section due to falsification of information or powering off of the vehicle-mounted device, leading to inaccurate fee calculations.
Innovation Solution
A vehicle management system that includes a vehicle-mounted device equipped with a photographing device for image capture, a reception information detector for inter-vehicle communication, and a determination unit to identify and verify the correspondence between vehicles, allowing for the identification of vehicles with non-functional or falsified devices by transmitting images of unverified vehicles to a management device for recording as fraudulent candidates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If GPS-based position detection is used to determine travel section, then fee calculation can be performed without roadside devices, but accuracy deteriorates due to information falsification or device powering off
Solution Approach 1:
The patent introduces an intermediary verification mechanism using photographing devices and inter-vehicle communication to mediate between the vehicle-mounted device and the fee calculation system. This intermediary layer captures images of the vehicle and verifies communication signals, preventing falsification while maintaining GPS-based fee calculation capability.
Solution Approach 2:
The system implements feedback by having photographing devices capture vehicle images and verify whether captured vehicles match the vehicle-mounted device's claims. This feedback loop provides verification of travel sections, preventing information falsification while maintaining the versatility of GPS-based fee calculation.
2Device complexity
If only inter-vehicle communication is used for vehicle identification, then device complexity is reduced, but reliability deteriorates due to inability to verify actual vehicle presence
Solution Approach 1:
The patent merges inter-vehicle communication with photographing device verification. The system combines data from communication signals with visual confirmation from images, creating a unified identification process that maintains simplicity while enhancing reliability through multiple verification methods.
Solution Approach 2:
The photographing device serves as an intermediary that provides visual verification of vehicle presence. This intermediary component validates the authenticity of inter-vehicle communication data, ensuring that identified vehicles actually exist and have not been falsely reported.
3Reliability
If photographing device is added to verify vehicle identity, then identification reliability is improved, but device complexity increases
Solution Approach 1:
The system uses self-service by having vehicles photograph each other using their own photographing devices. Each vehicle-mounted device serves as both the subject to be verified and the verification tool, eliminating the need for external verification infrastructure and reducing overall system complexity while maintaining high reliability.

AI summary
A vehicle-mounted device is configured to identify another vehicle from an image generated by photographing the surroundings of a host vehicle using a photographing device. The vehicle-mounted device is configured to detect identification information of the another vehicle on the basis of a signal received via inter-vehicle communication with a vehicle-mounted device of the another vehicle located in a communication range of the inter-vehicle communication. The vehicle-mounted device is configured to determine whether the identification information corresponding to the another vehicle identified from an image has been acquired.
