Vehicle Notification Lighting for Multiple Pedestrian Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic driving vehicles struggle to effectively communicate their recognition of pedestrians to multiple individuals around the vehicle, leading to anxiety due to unpredictable behavior, as existing systems can only direct a single light source towards one person at a time.
Innovation Solution
A notifying device mounted in the vehicle, comprising a controller and a light emitter, which determines the directions of multiple pedestrians using detection results from sensors like cameras and emits light patterns or icons in those directions, allowing each pedestrian to confirm the vehicle's recognition without requiring the light emitter to rotate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single movable device with light source is used to notify pedestrians, then the device can be directed toward one person, but it cannot simultaneously notify multiple pedestrians
Solution Approach 1:
The single movable device is divided into multiple fixed light-emitting units positioned at different locations on the vehicle. Each unit independently emits light in a fixed direction, allowing simultaneous notification of multiple pedestrians without requiring mechanical movement or rotation of the devices.
2Adaptability or versatility
If the light emitter rotates to track multiple pedestrians, then each pedestrian can be notified, but the system becomes more complex and response time is reduced
Solution Approach 1:
Multiple light-emitting units are pre-positioned at different locations on the vehicle body before the vehicle operates. Each unit is fixed in a specific direction, so when pedestrians are detected, the system can immediately activate the appropriate units without any rotation or movement delay, providing instant notification to multiple pedestrians simultaneously.

AI summary
A notifying method includes detecting an object existing in a periphery of the vehicle, and emitting a visible light to irradiate at least a part of the periphery of the vehicle in a direction of the object with an irradiation pattern. A color of the visible light irradiated is a complementary color of a color of a road surface.
