Remote ADAS Control via V2I Override Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-Infrastructure (V2I) communication systems are limited in their ability to provide comprehensive control over Advanced Driver-Assistance Systems (ADAS) as they rely on localized sensing and lack the capability to monitor and control vehicles beyond their detection range, restricting the effectiveness of ADAS in managing traffic situations and enhancing safety.
Innovation Solution
The integration of remote roadway infrastructure with in-vehicle ADAS systems allows for selective remote control of ADAS capabilities, enabling better performance by exchanging control messages and data between vehicles and roadside units (RSUs) to enhance ADAS functionality, switch between local and remote control based on conditions, and optimize ADAS countermeasures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If localized sensing and control is used in current V2I systems, then device complexity is reduced, but the ability to monitor and control vehicles beyond detection range deteriorates
Solution Approach 1:
The patent merges localized V2I communication with cloud-based remote ADAS control to create a hybrid system. The local RSU handles immediate communication needs while the remote cloud system provides comprehensive traffic situation awareness and control capabilities, combining the advantages of both distributed and centralized approaches.
Solution Approach 2:
The patent introduces a cloud-based remote ADAS controller as an intermediary between vehicles and infrastructure. This mediator receives data from multiple RSUs and vehicles, processes comprehensive traffic information, and provides coordinated control decisions, enabling extended monitoring and control beyond individual RSU detection ranges.
2Reliability
If remote ADAS control is implemented, then ADAS performance and safety are improved, but control authority and system complexity increase
Solution Approach 1:
The patent implements dynamic control authority management where the system can switch between local and remote ADAS control based on real-time conditions. The remote controller can assume control when beneficial for safety or traffic management, and local control can be restored when appropriate, creating a flexible and adaptive control architecture.
Solution Approach 2:
The patent changes the operational parameters of ADAS control by introducing remote control capabilities that can override local ADAS decisions. The system adjusts control parameters dynamically based on traffic situations, allowing remote intervention when local sensing or control limitations prevent optimal safety outcomes.
3Adaptability or versatility
If selective remote control is implemented, then ADAS functionality is enhanced, but communication requirements and data transmission needs increase
Solution Approach 1:
The patent extracts only the essential control functions and parameters needed for remote ADAS operation, transmitting selectively rather than continuously. The system transmits vehicle state data, ADAS capability information, and control decisions only when relevant to remote control operations, reducing unnecessary data transmission while maintaining enhanced functionality.
Data Source
AI summary
An example method broadcasts a first message to a vehicle entering a coverage area of an access point proximate a roadway, and receives a response from the vehicle under local advanced drive assistance system (ADAS) control within the coverage area. The method determines, based on the ADAS capability of the vehicle, whether to assume a first remote ADAS control of the vehicle by a remote ADAS controller communicating with the vehicle via the access point. In response to determining to assume the first remote ADAS control, the method requests override permission for the first remote ADAS control from a local ADAS controller of the vehicle, receives an override confirmation from the local ADAS controller permitting the first remote ADAS control within the coverage area of the access point, and responsive to receive the override confirmation, provides a first remote ADAS control instruction to the local ADAS controller of the vehicle.
