Vehicle Yield Notification Display for Rear Driver Intent Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous driving scenarios, rear vehicles may not accurately grasp the intention of the host vehicle when it is giving way to others, leading to potential misunderstandings and safety risks, as existing technologies do not effectively communicate this intention to the rear vehicle.
Innovation Solution
An information notification device and method that utilize a first display on the host vehicle to visually convey to the rear vehicle that the host vehicle is giving way to others, including the time until the vehicle starts, and a second display to provide warnings when the host vehicle is detected passing, using a front camera-generated image to clarify the situation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the host vehicle stops to give right of way to others during autonomous driving, then the intention to yield is conveyed to pedestrians and other road users, but the rear vehicle cannot correctly grasp the intention of the host vehicle
Solution Approach 1:
The patent introduces a display device as an intermediary to transmit intention information from the host vehicle to the rear vehicle. The display shows icons or images representing the host vehicle's intention (e.g., yielding to pedestrians), making this information visible to the rear vehicle's driver and preventing misunderstanding
Solution Approach 2:
The patent creates a visual copy of the host vehicle's intention state and transmits it to the rear vehicle. By displaying icons or images that represent the current situation and intended action, the rear vehicle driver can grasp the host vehicle's intention without directly observing the physical scene
2Loss of information
If light or sound is emitted from the host vehicle to notify the rear vehicle, then some information is transmitted, but the driver of the rear vehicle may feel anxious because the driver cannot grasp the intention of the host vehicle
Solution Approach 1:
The patent uses different display colors or visual patterns to represent different intention states. For example, green may indicate safe to pass, yellow may indicate caution, and red may indicate do not pass. This visual coding system allows the rear vehicle driver to quickly understand the host vehicle's intention without ambiguity, reducing anxiety
Solution Approach 2:
The patent replaces ambiguous mechanical signals (light/sound emissions) with clear visual information display. Instead of using headlights or horns that may be misinterpreted, the system uses a dedicated display showing icons and images that clearly communicate the host vehicle's intention and the reason for stopping

AI summary
An information notification device is provided with a notification control unit configured to notify a rear vehicle that a host vehicle is giving right of way to others via a first display provided in the host vehicle so as to be visually recognized from the rear vehicle in a stop state in which the host vehicle is stopped in order to give right of way to others.
