Regional Driving Message Delivery for Vehicles Without OBUs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intelligent transportation systems face challenges in enabling vehicles with low networking levels to participate in high-level networking, leading to inadequate synchronization of road-side information, as many vehicles lack on-board units (OBU) for receiving vehicle-to-everything (V2X) messages, resulting in inefficient traffic management.
Innovation Solution
A centralized vehicle-infrastructure cooperation message is pushed to conveyances, using a V2X-based standardized message, where a central platform subsystem issues driving-related messages to regional platform subsystems, which then send these messages to conveyances, facilitating intelligent control of traffic systems without the need for on-board units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles are equipped with on-board units (OBU) to receive V2X messages, then the reliability of receiving road-side information is improved, but the device complexity and cost increase
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the road-side infrastructure and conventional vehicles without OBUs. The gateway receives V2X messages from road-side units and forwards them to vehicles through existing communication interfaces, enabling information delivery without requiring vehicles to have OBU equipment.
Solution Approach 2:
The system creates a copy of the V2X message transmission function at the gateway level. Instead of requiring each vehicle to have OBU capability, the gateway replicates the message distribution function, sending information to vehicles through alternative communication channels that do not require onboard V2X hardware.
2Adaptability or versatility
If all vehicles are equipped with OBU for V2X communication, then the adaptability of the traffic system is improved, but the ease of manufacture and deployment deteriorates
Solution Approach 1:
Instead of equipping vehicles with OBU to enable V2X communication, the patent inverts the approach by bringing the V2X message distribution function to the gateway/infrastructure side. Conventional vehicles without OBUs can receive processed information through standard communication interfaces, eliminating the need for vehicle-side hardware modifications.
Solution Approach 2:
The gateway device performs multiple functions: it receives V2X messages from road-side units, processes and adapts the information, and distributes it to various types of vehicles through different communication channels. This multi-functional approach allows the system to serve both connected and conventional vehicles without requiring vehicle-specific modifications.
3Productivity
If V2X messages are pushed to all conveyances, then the productivity of traffic management is improved, but the loss of information increases due to inadequate synchronization
Solution Approach 1:
The gateway device implements feedback mechanisms to track which vehicles have received which messages. By monitoring reception status and vehicle locations, the system can identify missing information and retransmit or redirect messages to ensure complete information delivery to all target vehicles.
Solution Approach 2:
The system performs preliminary actions by pre-processing V2X messages at the gateway before distribution. Information is validated, formatted, and prepared in advance, ensuring that when messages are pushed to vehicles, they are complete and synchronized, reducing information loss during transmission.

AI summary
A method and apparatus for driving control, a device, a medium and a system are provided. An embodiment of the method includes: receiving, at a conveyance located in a first geographic region, a first message from a device platform subsystem associated with the conveyance, the first message including information related to a first regional platform subsystem, and the first regional platform subsystem including a driving-related message related to the first geographic region; and sending a second message to the first regional platform subsystem, the second message including conveyance-related information of the conveyance. Then, receiving, from the first regional platform subsystem, a driving-related message associated with the conveyance in the first geographic region, where the driving-related message associated with the conveyance is determined based on the conveyance-related information and is used for a driving control on the conveyance in the first geographic region.
