IX Node Assist Zone Mapping for Vehicle Application Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles operating with autonomous or driver assist features face challenges in utilizing information from smart infrastructure nodes (IX Nodes) due to a lack of a priori data about their assist zones, leading to ineffective navigation and operation in complex scenarios.
Innovation Solution
Vehicles retrieve data about IX Node assist zones, including broadcast range, field of view, and available services before entering the zone, enabling informed application selection and operation.

Engineering Contradiction Analysis
1Reliability
If vehicles rely on IX Node sensing to navigate intersections, then navigation capability in complex scenarios is improved, but the vehicle cannot effectively utilize IX Node information due to lack of a priori data about assist zones
Solution Approach 1:
The system performs preliminary actions by providing vehicles with a priori information about IX Node assist zones, broadcast ranges, and field of view areas before the vehicle reaches these zones. This advance information delivery enables vehicles to prepare and effectively utilize IX Node sensing data when entering assist zones, resolving the information loss problem while maintaining navigation reliability.
2Area of stationary object
If IX Node radio coverage covers the entire driving region, then coverage area is improved, but the vehicle still cannot make use of assistive messages without knowing where they occur
Solution Approach 1:
The system introduces an intermediary mechanism (map data layer) that mediates between the IX Node radio coverage and the vehicle's utilization of assistive messages. This intermediary provides structured information about assist zones and field of view areas, enabling the vehicle to effectively use IX Node messages within the covered area without requiring the vehicle to independently discover zone boundaries.
3Ease of operation
If the vehicle routes around difficult intersections to avoid complexity, then operational simplicity is maintained, but the vehicle cannot detect absence of expected service and change modes or paths
Solution Approach 1:
The system implements feedback by enabling vehicles to detect the absence of expected IX Node service through the provided a priori information about assist zones. When vehicles enter zones where IX Node assistance is expected but not received, they can detect this service absence and adaptively change their operational mode or routing path, thereby improving versatility while maintaining operational simplicity through informed decision-making.

AI summary
A system and method for operating a vehicle operating on a route that will pass within a predetermined distance of a smart infrastructure node (IX Node) includes: retrieving, prior to receiving a message from the IX Node, data about the IX Node including (a) an IX Node assist zone based on an effective broadcast range of the IX Node, (b) an IX Node field of view area that is within the IX Node assist zone and that is defined by a field of view of one or more IX Node sensors, and (c) available services from the IX Node; and selecting a vehicle application for operation on the route while in the IX Node assist zone based on the IX Node field of view area, and the available services from the IX Node, and/or a type and accuracy of one or more IX Node sensors.
