Vehicular Recording Control for Unnoticed Post-Event Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular recording systems struggle to properly record events, especially in cases where drivers, particularly elderly individuals, may not notice minor accidents due to poor visibility or other factors.
Innovation Solution
A vehicular recording control device that includes a capture-data acquisition unit, an event detection unit, a stop detection unit, and a recording control unit. This device acquires and saves capture data from a first capturing unit, detects events and vehicle stops, and controls recording to ensure proper capture of data before and after an event, even if the driver continues traveling without noticing the event.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the recording system only saves capture data for a fixed first period after event detection, then the recording duration is limited and manageable, but events where the driver continues traveling without noticing (such as minor accidents with elderly drivers or poor visibility conditions) cannot be properly recorded
Solution Approach 1:
The recording system dynamically adjusts the recording duration based on vehicle stop detection. When an event is detected, the system initially records for a first period, then extends to a second period if the vehicle continues moving, and potentially to a third period if the driver remains unaware. This dynamic extension ensures reliable event recording while adapting to the driver's response time and awareness state.
Solution Approach 2:
The system uses stop detection unit feedback to determine whether to extend the recording period. The feedback mechanism monitors vehicle stop status and triggers period extension when the vehicle continues moving after an event, allowing the system to adaptively respond to driver behavior and ensure complete event documentation.
2Reliability
If the system extends recording to cover prolonged periods after events, then complete event documentation is achieved, but storage space is consumed and recording efficiency decreases
Solution Approach 1:
The recording period is dynamically structured into multiple phases (first period, second period, third period) that are activated based on vehicle stop detection. This dynamic structure allows the system to extend recording only when necessary (when the driver continues traveling without noticing the event), thereby maintaining documentation completeness while avoiding unnecessary prolonged recording that would waste storage space and reduce efficiency.
3Reliability
If the system continuously monitors vehicle stop status to determine recording extension, then accurate event capture is achieved, but device complexity increases
Solution Approach 1:
The stop detection unit serves as an intermediary component that bridges event detection and recording control. This intermediary monitors vehicle stop status and provides feedback to the recording control unit, enabling accurate event capture through a modular and manageable system architecture that avoids excessive complexity while maintaining reliability.

AI summary
A vehicular recording control device includes a capture-data acquisition unit configured to acquire capture data captured by a first capturing unit that captures a vicinity of a vehicle, an event detection unit configured to detect an event to the vehicle, a stop detection unit configured to detect a stop of the vehicle after the event detection unit detects the event, and a recording control unit configured to save, in a case where the event is detected by the event detection unit, as event record data, at least capture data corresponding to a first period resulting from the detection of the event.
