Vehicle Dashcam View Control for Storage-Limited Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving video recording systems for vehicles are limited in their ability to dynamically adjust the field of view and storage based on driving conditions, leading to inefficiencies in data capture and storage.
Innovation Solution
A control method for a driving video recording system that includes a camera module, first and second memories, and a processor to determine view conditions and selectively expand the field of view and storage region based on horizontal and vertical expansion conditions, such as lane count, road type, speed, steering angles, ADAS warnings, and time of day, to optimize data capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the field of view is expanded to record more information, then the quantity of recorded information increases, but the storage capacity is exceeded
Solution Approach 1:
The patent applies dynamics by making the field of view adjustable based on driving conditions. The controller dynamically changes the field of view between a first region (normal conditions) and a second region (expanded conditions) according to real-time parameters such as vehicle speed, steering angle, and road conditions. This resolves the contradiction by allowing the system to expand information capture only when necessary, rather than continuously overfilling storage.
Solution Approach 2:
The patent changes the parameter of field of view size based on driving conditions. When conditions indicate potential hazards (e.g., high speed, sharp steering, curved roads), the system expands the field of view to capture more information. In normal conditions, it narrows the field of view to conserve storage space. This parameter adjustment directly resolves the contradiction between recording quantity and storage capacity.
2Productivity
If the field of view is narrowed to conserve storage space, then storage efficiency improves, but the quantity of recorded information decreases
Solution Approach 1:
The system dynamically adjusts the field of view based on real-time driving conditions. During normal driving, it narrows the field of view to the first region to improve storage efficiency. When hazard conditions are detected (high speed, sharp steering, curved roads), it automatically expands to the second region to capture necessary information. This dynamic adjustment resolves the contradiction by optimizing storage efficiency without permanently sacrificing information quality.
Solution Approach 2:
The patent changes the field of view parameter based on driving condition parameters. The controller monitors speed, steering angle, road curvature, and other factors, then adjusts the field of view size accordingly. This ensures storage efficiency is maintained during normal operation while information quality is preserved when needed, resolving the contradiction between efficiency and quantity.
3Quantity of substance
If the field of view is expanded in all conditions, then the quantity of recorded information increases, but the storage capacity is exceeded and normal driving conditions waste space
Solution Approach 1:
The patent applies local quality by applying different field of view settings to different driving conditions. Instead of using a uniform expanded field of view for all situations, the system applies a narrow field of view (first region) during normal conditions and an expanded field of view (second region) only during specific hazard conditions. This localized approach resolves the contradiction by ensuring storage space is used efficiently while still capturing necessary information when needed.
Solution Approach 2:
The system changes the field of view parameter based on driving condition parameters such as vehicle speed, steering angle, and road curvature. When these parameters indicate normal conditions, the field of view is set to the first region. When parameters indicate potential hazards, the field of view expands to the second region. This conditional parameter change resolves the contradiction by preventing storage waste during normal operation while ensuring information quality during critical situations.

AI summary
A driving video recording system includes a camera module for monitoring surroundings of a vehicle, a first memory for storing an image transmitted from the camera module, a second memory for storing a computer program for controlling storage of the image, and a controller including a processor to execute the computer program. The processor determines whether a view condition is satisfied through execution of the computer program, selects one of a first region or a second region for a field of view of the camera module according to the determination, and stores the image obtained by the camera module according to the selection.
