Parked Vehicle Impact Recording With Battery-Aware Camera Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle monitoring systems that use acceleration sensors to record images of a vehicle's surroundings during parking increase power consumption, which can drain the vehicle's battery.
Innovation Solution
A vehicle monitoring system that employs an acceleration sensor operated with a constant power supply from the vehicle's battery, activating image recording devices only when the detected acceleration exceeds a predetermined value, and includes a monitoring control device to manage power consumption by calculating remaining battery capacity and determining if recording can be performed without compromising the vehicle's ability to start the engine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the acceleration sensor and image recording devices are constantly activated during parking to detect impacts and record images, then the monitoring capability and image recording reliability are improved, but the power consumption of the battery increases significantly
Solution Approach 1:
The acceleration sensor operates periodically rather than continuously - it is activated only when impact detection is needed (during parking) and deactivated when not needed (during vehicle operation). The image recording devices are activated periodically only when impact is detected by the acceleration sensor, rather than running continuously. This periodic activation pattern significantly reduces power consumption while maintaining monitoring reliability when required.
Solution Approach 2:
The system dynamically adjusts the operational state of different components based on vehicle status. The monitoring control device determines whether the vehicle is parked or in operation, and accordingly activates or deactivates the acceleration sensor and image recording devices. This dynamic control ensures high reliability during parking monitoring while minimizing power consumption during normal vehicle operation.
2Reliability
If the image recording devices are activated whenever the acceleration sensor detects impact during parking, then the image recording capability is improved, but the battery may be depleted and the vehicle may fail to start
Solution Approach 1:
The monitoring control device continuously monitors battery capacity and uses this feedback to make intelligent decisions about image recording activation. When impact is detected by the acceleration sensor, the control device checks the current battery capacity before activating image recording. If battery capacity is sufficient, recording is activated; if not, recording is suppressed. This feedback mechanism ensures image recording capability is maintained when possible while preventing battery depletion that would prevent vehicle startup.
Solution Approach 2:
The system changes the operational parameter of image recording devices based on battery capacity thresholds. When battery capacity is above a predetermined threshold, the system allows image recording activation upon impact detection. When battery capacity falls below the threshold, the system changes the parameter to prevent recording activation, even if impact is detected. This parameter change strategy balances recording capability with battery conservation.

AI summary
A vehicle monitoring system includes: an acceleration sensor mounted on a vehicle and operated by a first power supply that is constantly supplied from a battery of the vehicle; and a monitoring control device that operates by the first power supply and activates one or more devices that record an image of a periphery of the vehicle when the acceleration sensor detects an acceleration of a predetermined value or more while the vehicle is parked, and causes the image to be recorded.
