External Vehicle Display for Machine-Readable Location Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle detection systems face inaccuracies in associating vehicle location data with images, requiring additional hardware like GPS and IMU, and are cumbersome due to the need for data association between received data and image data.
Innovation Solution
The use of an external vehicle display with LEDs that transmit vehicle data, allowing cameras to extract location information directly from the display, eliminating the need for data association and reducing hardware requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional vehicle detection systems use GPS and IMU with data association between received data and image data, then vehicle location can be determined, but the system becomes complex and prone to inaccuracies in associating data
Solution Approach 1:
The patent uses the existing external vehicle display as a copy/alternative source for location information. Instead of relying on GPS/IMU data that needs to be associated with images, the system extracts location data directly from the visual display that is already present on the vehicle exterior. This eliminates the complex data association process while maintaining location determination capability.
Solution Approach 2:
The patent extracts location information directly from the external vehicle display that is already mounted on the vehicle. By taking out the location data from the display interface rather than from GPS/IMU systems, the patent simplifies the overall system architecture and eliminates the need for complex data association between multiple data sources.
2Reliability
If additional hardware like GPS and IMU is added to improve vehicle detection accuracy, then location data can be obtained, but hardware complexity increases
Solution Approach 1:
The patent makes the external vehicle display serve multiple functions: its original purpose for human recognition and an additional function for transmitting machine-readable location data to other vehicles. This multi-functionality eliminates the need for separate GPS/IMU hardware while maintaining reliable location determination.
Solution Approach 2:
The external vehicle display, which is already present on the vehicle for its original purpose, is utilized to also provide location information for vehicle detection. The existing hardware serves itself by providing dual functionality, eliminating the need for additional dedicated location hardware.
3Loss of information
If vehicle data is transmitted using traditional communication methods, then information can be exchanged, but the system requires separate communication hardware and data association processes
Solution Approach 1:
The patent merges the information transmission function with the external vehicle display that is already present on the vehicle. By combining location data transmission with the existing display hardware, the patent eliminates the need for separate communication hardware and simplifies the system architecture while maintaining complete information exchange.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach improves vehicle detection accuracy and reduces hardware complexity by enabling direct extraction of vehicle location data from the external display, enhancing vehicle communication and control systems.
Implementation Method 1
The external vehicle display includes a plurality of light emitting diodes (LEDs), wherein a first subset of the plurality of LEDs displays a human-recognizable image, and wherein a second subset of the plurality of LEDs displays the vehicle data about the first vehicle.
Data Source
AI summary
Examples of techniques for vehicle communication between a first vehicle and a second vehicle are disclosed. An example method includes displaying, on an external vehicle display of the first vehicle, vehicle data. The method further includes capturing, by a camera of the second vehicle, an image of the external vehicle display. The method further includes processing, by a processing device associated with the second vehicle, the image to extract the vehicle data about the first vehicle. The method further includes determining, by the processing device, a position of the first vehicle relative to a position of the second vehicle based at least in part on the vehicle data. The method further includes controlling, by the processing device associated with the second vehicle, the second vehicle based at least in part on the position of the first vehicle relative to the position of the second vehicle.
