Driving Assistance Planning Using Surrounding Vehicle Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not consider improving the traveling safety and reliability of vehicles that are not equipped with a driving assistance device using a high-definition map.
Innovation Solution
A driving assistance control device that recognizes surrounding vehicles, determines their traveling reliability based on high-definition map usage, and creates a driving assistance plan to enhance the safety and reliability of the subject vehicle by following or avoiding vehicles with higher reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a driving assistance device uses a high-definition map to improve the traveling safety and reliability of the subject vehicle, then the traveling safety and reliability of the subject vehicle improve, but the traveling safety and reliability of other vehicles that are not equipped with such a device do not improve
Solution Approach 1:
The patent introduces an intermediary mechanism where the subject vehicle communicates its high-definition map usage status to surrounding vehicles. This allows surrounding vehicles to benefit indirectly from the subject vehicle's advanced capabilities through information sharing, thereby improving their traveling reliability without requiring them to be equipped with the same expensive hardware
Solution Approach 2:
The patent creates a virtual copy of the high-definition map information by having the subject vehicle transmit its map usage status to surrounding vehicles. This allows surrounding vehicles to access replicated information about road conditions and lane data without needing their own expensive high-definition map systems, effectively copying the benefit of advanced navigation

AI summary
In a driving assistance control device, a surrounding vehicle recognition unit recognizes a position of a surrounding vehicle existing around a subject vehicle. A surrounding vehicle control information acquisition unit acquires surrounding vehicle control information including information as to whether or not the surrounding vehicle is performing traveling control using a high-definition map. A surrounding vehicle reliability determination unit determines traveling reliability of the surrounding vehicle. A driving assistance plan creation unit creates a driving assistance plan in which the subject vehicle is controlled to travel along the surrounding vehicle with the high traveling reliability as much as possible, or a driving assistance plan in which the subject vehicle is controlled not to travel along the surrounding vehicle with the low traveling reliability as much as possible on the basis of the traveling reliability of the surrounding vehicle.
