Remote Vehicle Control Using Roadside Sensing to Cut Uplink Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote driving technologies face inefficiencies due to the large amount of data that needs to be transmitted upstream, leading to inefficient use of wireless transmission resources, particularly in 5G networks, especially in harsh environments where remote driving is crucial.
Innovation Solution
A vehicle control method and apparatus that establish communication connections with roadside devices to dynamically adjust the data to be transmitted by the vehicle based on the sensing capability of the roadside device, reducing the need for vehicles to transmit road environment information directly to the remote control end, and instead using roadside devices to relay this information for control instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle transmits all necessary data (vehicle status information and road environment information) to the remote control end, then the remote control end can make accurate control decisions, but the upstream bandwidth occupation increases and wireless transmission resources are used inefficiently
Solution Approach 1:
The patent introduces a roadside device as an intermediary between the vehicle and the remote control end. The roadside device collects road environment information using its sensors (cameras, radars, etc.) and transmits this information to the remote control end, eliminating the need for the vehicle to transmit the same data. This mediator approach reduces upstream bandwidth occupation while ensuring the remote control end receives accurate environmental data for control decisions.
Solution Approach 2:
The roadside device performs self-service by autonomously collecting, processing, and transmitting road environment information to the remote control end without requiring the vehicle to perform these functions. The roadside device's sensing capabilities are utilized to provide environmental data, reducing the communication burden on the vehicle and optimizing wireless resource usage.
2Loss of information
If the vehicle transmits detailed road environment information, then the remote driver has better situational awareness, but the amount of uplink transmitted data increases
Solution Approach 1:
The roadside device acts as an intermediary that collects and transmits road environment information to the remote control end. This eliminates the need for the vehicle to transmit detailed environmental data, reducing uplink transmitted data while ensuring the remote driver receives comprehensive situational awareness information through the roadside device's sensing capabilities.
3Reliability
If the vehicle continuously transmits status parameters and visual information, then the remote control end maintains real-time vehicle monitoring, but wireless transmission resources are used inefficiently
Solution Approach 1:
The roadside device serves as a mediator that provides real-time road environment information to the remote control end, eliminating the need for the vehicle to continuously transmit this data. The vehicle only transmits its status parameters, maintaining real-time monitoring capability while significantly improving wireless transmission resource efficiency by leveraging the roadside device's sensing and communication capabilities.
