Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic driving systems face challenges in accurately determining the impact range of interference on sensor detection results, leading to reduced detection accuracy and potential safety issues due to mutual interference between vehicle-mounted sensors.
Innovation Solution
The detection apparatus reports an interfered range of interference, including indication information such as interfered distance, speed, or angle ranges, along with interference intensity, to the fusion apparatus, enabling it to improve the confidence and accuracy of the fusion result.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detection apparatus sends only basic detection results to the fusion apparatus, then the communication load is reduced, but the fusion apparatus cannot accurately determine the impact range of interference, leading to reduced detection accuracy
Solution Approach 1:
The interference information is segmented into multiple dimensions including interfered distance range, interfered speed range, and interfered angle range. Each dimension is independently reported to the fusion apparatus, allowing comprehensive characterization of the interference impact without overwhelming communication load.
Solution Approach 2:
The patent extends the interference reporting from a single dimension (presence/absence of interference) to multiple dimensions (distance, speed, angle ranges). This dimensional expansion enables the fusion apparatus to accurately determine the interfered range in the detection result by considering interference impact across multiple parameters simultaneously.
2Reliability
If the detection apparatus reports detailed interference information including multiple ranges and intensity, then the fusion apparatus can improve detection accuracy, but the data transmission volume and processing complexity increase
Solution Approach 1:
The patent applies local quality by providing different levels of interference information for different regions in the detection space. The interfered range is characterized separately for distance, speed, and angle dimensions, allowing the fusion apparatus to apply appropriate confidence adjustments only to the affected regions rather than uniformly processing all detection data.
Solution Approach 2:
The patent changes the parameter representation of interference information from simple binary (interfered/not interfered) to multi-parameter ranges (distance range, speed range, angle range) with associated intensity values. This parameter expansion enables more precise reliability assessment while maintaining structured data format that simplifies processing.
3Measurement precision
If the detection apparatus uses interval-based interfered range representation, then the accuracy of describing the interfered range is improved, but the data structure complexity increases
Solution Approach 1:
The interfered range is segmented into discrete intervals along each dimension (distance, speed, angle). By representing continuous ranges as intervals, the patent achieves precise description of the interfered regions while maintaining a structured, computationally efficient data format that balances accuracy and complexity.
