Autonomous Vehicle Display Cues for Passenger Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack the ability to communicate effectively with passengers and others outside the vehicle, as they do not have a human driver to convey information through physical gestures or direct communication.
Innovation Solution
The implementation of a notification system on autonomous vehicles that uses a display to convey information based on distance, context, and environmental factors, adjusting the content and brightness of notifications to ensure legibility and recognition by passengers, including the use of color, alphanumeric characters, icons, and dynamic adjustments based on speed, traffic, and weather.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a notification system with display is implemented on autonomous vehicles, then communication effectiveness with passengers is improved, but device complexity increases
Solution Approach 1:
The notification system acts as an intermediary communication channel between the autonomous vehicle system and passengers. The display device serves as a mediator that translates vehicle status, location, and operational information into visual notifications that passengers can understand, effectively bridging the communication gap without requiring direct human-driver interaction.
Solution Approach 2:
The patent replaces the mechanical communication methods used by human drivers (gestures, verbal communication, physical signals) with an electronic notification system. The display-based notification system substitutes the biological/mechanical communication capabilities of human drivers with an automated electronic information delivery system that provides consistent, clear, and comprehensive communication.
2Illumination intensity
If dynamic brightness adjustment is implemented based on environmental factors, then legibility and recognition are improved, but use of energy increases
Solution Approach 1:
The notification system dynamically adjusts display brightness based on real-time environmental conditions such as ambient light levels, time of day, and weather conditions. This dynamic adaptation ensures optimal legibility across varying conditions while avoiding excessive energy consumption by only increasing brightness when necessary for visibility.
Solution Approach 2:
The system changes the brightness parameter of the display based on environmental factors. By monitoring ambient conditions and adjusting the illumination intensity parameter accordingly, the system maintains effective communication with passengers while optimizing energy consumption - increasing brightness only when environmental conditions require enhanced visibility.
3Loss of information
If multiple notification types with additional information are displayed, then communication completeness is improved, but device complexity increases
Solution Approach 1:
The notification system segments information into multiple distinct notification types, each conveying specific aspects of vehicle status or passenger information. By dividing comprehensive communication into structured segments (e.g., arrival notifications, status updates, directional information), the system delivers complete information in an organized manner that manages complexity through systematic categorization rather than presenting all information simultaneously.

AI summary
Aspects of the disclosure provide for displaying notifications on a display of an autonomous vehicle 100. In one instance, a distance from the vehicle to a destination of the vehicle or a passenger may be determined. When the distance is between a first distance and a second distance, a first notification 650 may be displayed on the display. The second distance may be less than the first distance. When the distance is less than the second distance, a second notification 660 may be displayed on the display. The second notification provides additional information not provided by the first notification.
