Tele-Operated Driving Communication via Vehicle-Relayed Traffic Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concepts for tele-operated driving sessions do not effectively share full information available at the vehicle with the remote control center, limiting the remote control center's ability to control the vehicle efficiently.
Innovation Solution
The vehicle receives messages containing environmental information from traffic entities and forwards this information to the remote control center, enabling the remote control center to receive and utilize this information for controlling the vehicle, even if the remote control center is outside the transmission range of the traffic entity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the remote control center receives environmental information directly from traffic entities, then the information transmission is straightforward, but the remote control center is limited by transmission range and cannot receive messages outside its coverage area
Solution Approach 1:
The patent introduces the vehicle as an intermediary component that receives environmental information messages from traffic entities within transmission range and forwards this information to the remote control center. This mediator approach allows the remote control center to access environmental information indirectly when direct communication is not possible, resolving the transmission range limitation while maintaining system functionality.
2Loss of information
If the vehicle forwards all received messages to the remote control center, then complete environmental information is provided, but communication bandwidth and data processing load increase
Solution Approach 1:
The patent extracts and forwards only the essential environmental information content from received messages to the remote control center, rather than transmitting complete raw message data. This selective extraction approach provides sufficient environmental context for remote control operations while reducing communication bandwidth requirements and energy consumption.
3Adaptability or versatility
If the remote control center operates outside the transmission range of traffic entities, then operational flexibility is improved, but the ability to receive environmental information directly is lost
Solution Approach 1:
The vehicle serves as a mobile intermediary that extends the effective communication range of the remote control center. By receiving messages from traffic entities within its transmission range and relaying this information to the remote control center, the vehicle enables the control center to operate flexibly outside direct transmission range while maintaining access to environmental information.
