Autonomous Driving Event Recording With State Image Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information recording devices cannot determine whether an accident in an autonomous vehicle is caused by the driver's operation or the autonomous driving system, and they struggle to acquire the selected autonomous driving function or level after being installed post-manufacture.
Innovation Solution
An information recording device that acquires outside images and autonomous driving information, simultaneously displaying and recording the outside image and autonomous driving state image, allowing for the recording of both the external situation and autonomous driving control state for later analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an information recording device is added to a vehicle afterwards, then the device can record outside images and basic driving information, but it cannot directly acquire the selected autonomous driving function or autonomous driving level from the vehicle
Solution Approach 1:
The patent introduces an autonomous driving state image as an intermediary representation that visually encodes the autonomous driving function and level information. Instead of directly accessing the vehicle's autonomous driving system data, the device captures the display state showing the autonomous driving level (e.g., L2, L3) and function information, which then serves as a readable record for accident analysis
Solution Approach 2:
The device creates a visual copy of the autonomous driving system's state by photographing the display screen that shows the autonomous driving level and function information. This copied visual information is then recorded alongside the outside image, preserving the autonomous driving state without requiring direct system integration
2Measurement precision
If only outside images are recorded, then the external situation can be documented, but it is impossible to determine whether the driver's driving operation or the autonomous driving operation caused the accident
Solution Approach 1:
The patent merges the outside image with the autonomous driving state image into a single composite record. The autonomous driving state image is superimposed or displayed alongside the outside image, creating an integrated visual record that simultaneously shows both the external situation and the autonomous driving system state at the time of the accident
Solution Approach 2:
The patent adds a new dimension of information by incorporating the autonomous driving state image as a separate visual layer. Instead of merely adding data fields to the outside image, it creates a multi-dimensional visual record where the autonomous driving state can be independently viewed and analyzed alongside the external scene

AI summary
An information recording device acquires outside image information corresponding to an outside image obtained by photographing the outside of a moving body from the moving body; acquires autonomous driving information indicating a state of autonomous driving control of the moving body; acquires display information for simultaneously displaying at least a part of the outside image and an autonomous driving state image indicating the state of the autonomous driving control at a time of photographing the outside image, based on the outside image information and the autonomous driving information; and records the display information in a recording medium. The autonomous driving state image includes brake information indicating whether braking of the moving body is under the autonomous driving control.
