Convoy Vehicle Identification Using Shared Position Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for discriminating platoon vehicles struggle with accuracy when two forward vehicles travel side by side or swap positions, leading to reduced accuracy in identifying the correct platoon vehicle.
Innovation Solution
A platoon vehicle discrimination apparatus that acquires and compares identification information and location data from surrounding vehicles, using a storage section to store the first vehicle's information and an acquiring section to gather data from second vehicles, allowing for precise discrimination based on matching information and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If identification information is detected from forward vehicles using a detection section, then platoon vehicle discrimination can be performed, but accuracy is reduced when two forward vehicles run side by side or swap positions
Solution Approach 1:
The patent introduces a communication section as an intermediary that receives identification information from surrounding vehicles directly. This mediator approach allows the system to obtain identification information from multiple sources (detection section and communication section) and use both pieces of information together to resolve ambiguity when multiple forward vehicles are present, thereby improving discrimination accuracy
Solution Approach 2:
The patent adds a new dimension of information acquisition by implementing both detection-based identification (visual/sensor detection) and communication-based identification (direct data exchange from surrounding vehicles). This multi-dimensional approach allows the system to cross-validate identification information and accurately determine which forward vehicle belongs to the platoon, even when vehicles are positioned side by side or swapping positions
2Measurement precision
If only detection section is used to identify forward vehicles, then system complexity is low, but discrimination accuracy deteriorates in complex scenarios
Solution Approach 1:
The patent implements a multi-functional system where the communication section serves multiple purposes: receiving identification information from surrounding vehicles, exchanging data with platoon members, and providing backup identification methods. This universal approach allows the same communication infrastructure to handle various discrimination scenarios without requiring separate dedicated systems, thus improving accuracy while controlling complexity

AI summary
This convoy vehicle determination device can improve determination accuracy of a vehicle for forming a convoy. This convoy vehicle determination device, which determines convoy vehicle candidates, is provided with: an acquisition unit which acquires identification information of a third vehicle positioned in the periphery of any second vehicle from among the peripheral vehicles, read by the second vehicle, and, from the second vehicle, acquires position information of the second vehicle with respect to the third vehicle, specified by the second vehicle; and a determination unit which compares the identification information of the first vehicle and identification information of the third vehicle, and, on the basis of the results of said comparison and the position information of the second vehicle with respect to the third vehicle, determines a second vehicle from among the peripheral vehicles located in the periphery of the first vehicle as a convoy vehicle candidate.
