Vehicle Recognition Alert System for Driver Line of Sight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In traffic situations involving vehicles with automated driving functions, it is difficult for drivers to determine whether other vehicles recognize their presence, leading to anxiety and uncertainty, as looking towards a vehicle does not necessarily indicate recognition or appropriate action to avoid collisions.
Innovation Solution
A system on a saddle-ride type vehicle, such as a motorcycle, that inquires surrounding vehicles about their recognition using a camera, sensors, and communication units to identify the driver's line of sight and transmit recognition queries, outputting alert information on a display device if another vehicle is not recognized within the driver's range of interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver looks towards another vehicle to determine recognition, then the driver can potentially assess whether the other vehicle is aware of their presence, but this method is unreliable as looking does not necessarily indicate recognition or appropriate action to avoid collisions
Solution Approach 1:
The patent replaces the mechanical/visual method of determining recognition (driver looking at another driver's face) with an electronic information processing system. The output apparatus receives recognition information from other vehicles via communication units, processes this data, and presents it to the driver through display devices or audio output, thereby substituting direct visual assessment with automated information processing.
Solution Approach 2:
The patent introduces an intermediary system (the output apparatus) that mediates between other vehicles and the driver. Instead of the driver directly observing other drivers to assess recognition, the system acts as an intermediary that collects, processes, and presents recognition information from multiple sources, providing a more reliable and comprehensive assessment.
2Reliability
If the system provides alert information about all unrecognized vehicles, then the driver is fully informed of potential hazards, but this may cause unnecessary alerts and increase driver anxiety
Solution Approach 1:
The patent applies local quality by selectively presenting recognition information based on the driver's line of sight. The system determines the driver's attention direction and prioritizes presenting information about vehicles in that direction, rather than uniformly presenting all recognition information. This localized approach ensures critical information is highlighted while reducing unnecessary alerts about vehicles outside the driver's current focus.
Solution Approach 2:
The system implements feedback by continuously monitoring the driver's line of sight and dynamically adjusting which recognition information is presented. The output apparatus receives real-time data about driver attention direction and uses this feedback to selectively display or audio-output information about specific unrecognized vehicles, creating a responsive system that adapts to the driver's current needs.

AI summary
An output apparatus includes: an identifying unit that identifies a direction in which an occupant of a first vehicle is looking; a receiving unit that receives, from a second vehicle positioned in the direction identified by the identifying unit, information indicating whether or not the first vehicle is recognized by the second vehicle; and an output unit that outputs alert information to at least one alerting device among alerting devices attached to the first vehicle and the occupant of the first vehicle if the first vehicle is not recognized by the second vehicle.
