Autonomous Vehicle Display Cues for Passenger Recognition at Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack the ability to communicate effectively with passengers or other individuals outside the vehicle, as they do not have a human driver to make physical gestures or communicate through verbal means.
Innovation Solution
The implementation of a method to display notifications on an autonomous vehicle's display, which determines the distance to a destination or passenger and displays a first notification when within a certain range, and a second notification with additional information when closer, using color, alphanumeric characters, icons, and adjusting brightness based on context and distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If autonomous vehicles use simple visual notifications, then energy consumption is reduced, but communication effectiveness with passengers deteriorates
Solution Approach 1:
The notification system is segmented into multiple levels: a first notification displayed at a first distance that provides basic information, and a second notification displayed at a second distance that provides additional information. This segmentation allows the system to consume less energy by using simpler displays at greater distances while providing comprehensive information when the passenger is closer, thus resolving the contradiction between energy consumption and communication effectiveness.
Solution Approach 2:
The notification system dynamically adjusts its content and complexity based on the detected distance to the passenger. When the passenger is at the first distance, a simpler first notification is displayed; when the passenger approaches to the second distance, a more informative second notification is displayed. This dynamic adaptation optimizes energy consumption while maintaining effective communication throughout the approach sequence.
2Loss of information
If autonomous vehicles display detailed information notifications, then passenger recognition is improved, but device complexity increases
Solution Approach 1:
The display system is segmented into two operational modes corresponding to two distance ranges. The first notification mode uses simpler display elements when the passenger is at the first distance, while the second notification mode activates more detailed display elements when the passenger is at the second distance. This segmentation reduces overall device complexity by not requiring all display capabilities to be active simultaneously, while still achieving effective passenger recognition.
Solution Approach 2:
Different notification qualities are applied locally based on distance. The first notification uses a first set of display characteristics appropriate for longer distance viewing, while the second notification uses a second set of display characteristics optimized for closer viewing. This local quality differentiation improves passenger recognition without requiring the entire display system to operate at maximum complexity at all times.
3Loss of information
If autonomous vehicles use color-coded notifications, then vehicle identification is improved, but manufacturing precision requirements increase
Solution Approach 1:
Color coding is applied as a local quality enhancement to the notification system. The first notification and second notification can use different color schemes or color intensities appropriate to their respective distance ranges. This approach improves vehicle identification effectiveness while allowing for more relaxed manufacturing precision tolerances compared to a system requiring uniform high-precision color display across all operating conditions.

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.
