Automated Driving Log Storage for Low-Reliability Sensor Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited capacity of in-vehicle storage devices poses a risk of not being able to store necessary log data for automated driving control, particularly for detection information from recognition sensors, which is crucial for verification purposes due to its large data volume.
Innovation Solution
The automated driving system prioritizes storing log data from areas with low recognition reliability, allowing efficient use of storage capacity by preferentially storing target detection information related to these areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If log data of detection information is stored in the storage device, then verification capability is improved, but storage capacity is consumed
Solution Approach 1:
The patent applies local quality by differentiating storage priority based on spatial location (reliability area). Detection information is categorized into high reliability area and low reliability area, with preferential storage allocated to the low reliability area. This ensures that storage capacity is efficiently used by focusing on areas most critical for verification while maintaining verification capability.
2Productivity
If detection information from low reliability areas is preferentially stored, then verification efficiency is improved, but storage management complexity increases
Solution Approach 1:
The system performs preliminary action by pre-classifying detection information into high and low reliability areas based on predetermined criteria (e.g., detection distance, object type, environmental conditions). This classification is done in advance before storage, enabling automatic priority handling without complex real-time decision-making during storage operations, thus improving verification efficiency while keeping storage management relatively simple.

AI summary
An automated driving system one or more processors configured to recognize a situation around the vehicle from detection information detected by a recognition sensor and perform automated driving control based on a recognition result. The automated driving system execute a storing process of storing log data of the detection information in one or more storage devices while performing the automated driving control. In the storing process, the automated driving system specify a low reliability area around the vehicle where a reliability of the recognition result is low. When the low reliability area is specified, the automated driving system preferentially store the log data of target detection information that is the detection information related to the low reliability area.
