Vehicle Recording Apparatus Dynamic Voice Data Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses for vehicles do not effectively record voice data when imaging data is recorded without an event trigger, limiting the usefulness of the recorded data for troubleshooting purposes.
Innovation Solution
A recording apparatus equipped with an imaging data acquisition unit, a movement information acquisition unit, and a recording control unit that determines whether to record voice data based on movement information, such as vehicle speed and acceleration, to decide between recording first imaging data (with voice) or second imaging data (without voice).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If voice data is recorded in imaging data without event trigger, then the usefulness of recorded data for troubleshooting is improved, but user privacy protection deteriorates
Solution Approach 1:
The system changes the recording parameter (including voice data or not) based on the movement speed parameter. When the vehicle is moving at a lower speed, voice data is included in the recorded imaging data to provide context for troubleshooting. When the vehicle is moving at a higher speed, voice data is excluded to protect user privacy. This dynamic parameter adjustment resolves the contradiction by adapting the recording behavior to the operational context.
2Adaptability or versatility
If movement information is used to determine recording content, then the suitability of voice data recording is improved, but device complexity increases
Solution Approach 1:
The movement information acquisition unit and recording control unit serve multiple functions: they determine not only whether to include voice data but also can trigger event-based recording and manage recording modes (event recording mode vs. loop recording mode). This multi-functionality approach increases adaptability while managing complexity by consolidating control logic into existing system components rather than adding separate dedicated systems.

AI summary
A recording apparatus includes an imaging data acquisition unit, a movement information acquisition unit, an inter-vehicle detection unit and a recording control unit. The imaging data acquisition unit acquires imaging data and voice data. The movement information acquisition unit acquires movement information including a moving speed of the vehicle. The inter-vehicle detection unit detects an inter-vehicle distance between the vehicle and the other vehicle. The recording control unit determines that a voice recording condition is established when the moving speed of the vehicle is equal to or higher than a preset speed and the inter-vehicle distance is less than a preset distance, and causes the recording unit to record a first imaging data including the video data and the voice data when the voice recording condition is established or a second imaging data including the video data but not the voice data when the condition is not established.
