Vehicle Image Recording Controller Battery Charging Strategy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of a 12V low-voltage battery for image recording in vehicles leads to premature discharge, either due to insufficient charging for the set recording time or dark current consumption when the vehicle is parked, resulting in incomplete recording operations.
Innovation Solution
An apparatus and method that include a controller to manage battery charging and image recording operations based on input settings, fully charging the battery when the vehicle is started and adjusting recording times based on real-time battery charge levels to prevent discharge during parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a 12V low-voltage battery is used for image recording, then the cost is reduced by avoiding auxiliary battery mounting, but the battery is discharged prematurely due to insufficient charging time or dark current consumption
Solution Approach 1:
The controller performs preliminary charging of the battery when the vehicle is started, before the actual image recording operation begins. This advance charging ensures sufficient energy is stored to prevent premature discharge during the recording period, while still using only the existing 12V battery without additional auxiliary batteries.
2Use of energy by moving object
If the battery is charged fully when vehicle is started, then sufficient energy is available for image recording, but charging time is extended during vehicle operation
Solution Approach 1:
The charging control strategy is dynamic rather than static. The controller adjusts charging parameters based on real-time conditions including remaining recording time, current battery charge level, and power availability. This dynamic adjustment optimizes charging speed while ensuring sufficient energy is accumulated for the complete recording duration.
Solution Approach 2:
The controller continuously monitors battery charge amount and adjusts charging control accordingly. When the battery reaches sufficient charge level for the planned recording time, the controller automatically reduces or stops charging, preventing unnecessary extended charging time while ensuring adequate energy supply.
3Duration of action of moving object
If image recording is controlled based on real-time battery charge amount, then recording duration is optimized, but control complexity increases
Solution Approach 1:
The controller autonomously manages the entire process of determining recording duration based on battery charge levels without requiring complex external control systems or user intervention. It automatically calculates available recording time from current charge amount and adjusts operations accordingly, keeping the control system relatively simple while achieving optimized recording duration.

AI summary
An apparatus for controlling image recording of a vehicle includes: an input device that receives image recording setting information; and a controller that determines whether to control charging of a battery or an image recording operation according to whether the image recording setting information is input and whether the vehicle is in a starting state, thus controlling image recording while a vehicle is parked without the need for a separate battery and reducing an unnecessary increase in cost.
