Vehicle Object Detection Prioritization Under Bandwidth Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object detection apparatuses prioritize objects based solely on reflection intensity, which may not effectively account for varying traffic environments, potentially leading to incomplete or irrelevant data transmission to in-vehicle systems.
Innovation Solution
An object detection apparatus that receives information on surrounding objects and traffic environments, using a controller to determine priority for each object and selectively output information based on traffic conditions, such as road type, to ensure relevant data is transmitted to in-vehicle systems within bandwidth limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If object detection prioritizes only high reflection intensity objects, then detection simplicity is maintained, but detection accuracy and relevance to actual traffic safety deteriorates
Solution Approach 1:
The system changes the parameters used for priority determination from solely reflection intensity to a composite of reflection intensity, object type, and traffic environment. This allows the detection system to adapt its prioritization criteria dynamically, improving detection accuracy while maintaining operational simplicity through automated parameter integration.
Solution Approach 2:
The priority determination mechanism transitions from a static, single-criterion system to a dynamic, multi-criterion system that adapts to different traffic environments. The controller dynamically adjusts which objects receive higher priority based on real-time environmental context, enabling the system to handle varying detection scenarios effectively.
2Loss of information
If all detected object information is transmitted to in-vehicle apparatus, then information completeness is improved, but data transmission efficiency and processing load deteriorates
Solution Approach 1:
The system extracts and transmits only the most relevant object information based on calculated priorities, rather than transmitting all detected object data. This selective extraction approach maintains essential information completeness while significantly improving transmission efficiency by filtering out low-priority data that would consume bandwidth without adding safety-critical value.
Solution Approach 2:
Different levels of information detail are transmitted based on object priority and relevance to current traffic conditions. High-priority objects receive more detailed information transmission, while low-priority objects receive minimal or no transmission, optimizing the distribution of data resources according to local needs.
3Device complexity
If detection priority is based solely on reflection intensity, then device complexity is reduced, but adaptability to different traffic environments deteriorates
Solution Approach 1:
The detection system gains multi-functionality by integrating multiple detection criteria (reflection intensity, object type identification, traffic environment assessment) into a single unified priority determination mechanism. This allows the same system to effectively handle diverse traffic scenarios without requiring separate detection subsystems, maintaining reasonable complexity while dramatically improving adaptability.

AI summary
An object detection apparatus includes an input port that receives information on a plurality of objects in surroundings of a vehicle and information on a traffic environment of the vehicle, the plurality of objects being detected by a sensor installed on the vehicle, a controller that determines, based on the information on the plurality of objects and the information on the traffic environment, priority for each of the plurality of objects and determines first information based on the priority in a case where the total amount of information on the plurality of objects is greater than a determined value, the first information being information on part of the plurality of objects, and an output port that outputs the first information to an in-vehicle apparatus that controls the vehicle.
