Side Mirror Camera Power Modes for Parking Surveillance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle monitoring systems consume excessive power and battery life during parking, making long-term monitoring difficult due to constant operation of image sensors and ECUs.
Innovation Solution
The in-vehicle monitoring system controls the imaging operation of surround view cameras in stepwise power consumption modes, starting from low to high, based on detected objects, and adjusts the imaging direction of side mirror cameras to maintain a consistent field of view regardless of the mirror state, enabling efficient power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image sensor and ECU operate constantly during parking to monitor surrounding situations, then the monitoring reliability is improved, but the power consumption increases
Solution Approach 1:
The system implements periodic imaging operations during parking mode instead of continuous operation. The control section controls the imaging section to perform imaging at predetermined intervals, allowing the system to maintain monitoring capability while significantly reducing power consumption compared to constant operation.
Solution Approach 2:
The system dynamically adjusts the imaging operation based on detected motion. When motion is detected in a captured image, the system transitions from periodic low-power imaging to more frequent imaging or full monitoring mode, optimizing the balance between reliability and power consumption according to actual environmental conditions.
2Area of stationary object
If the imaging section operates in high power consumption mode to ensure comprehensive monitoring, then the monitoring coverage is improved, but the battery life decreases
Solution Approach 1:
The system uses periodic imaging at predetermined intervals during parking mode to maintain comprehensive monitoring coverage of surrounding areas while operating in a power-efficient manner, thereby extending battery life during extended parking periods.
Solution Approach 2:
The system performs partial imaging operations focused on detecting motion in surrounding areas rather than continuous full-resolution imaging, achieving adequate monitoring coverage with reduced power consumption suitable for extended battery operation.
3Use of energy by moving object
If the imaging operation is set to low power consumption mode during parking, then the power consumption is reduced, but the detection capability decreases
Solution Approach 1:
The system dynamically adjusts detection capability based on motion detection results. In low-power periodic imaging mode, the system maintains basic detection capability, and when motion is detected, it transitions to enhanced imaging modes that improve detection capability while managing power consumption appropriately.
Solution Approach 2:
The control section acts as an intermediary that processes captured images to detect motion, then triggers appropriate imaging responses. This intermediary processing layer enables the system to maintain low power consumption while preserving detection capability through intelligent image analysis rather than continuous high-power imaging.

AI summary
In-vehicle monitoring is disclosed. In one example, an in-vehicle monitoring apparatus includes an imaging section provided in a side mirror housing. A control section is configured to control the imaging direction of the imaging section in accordance with a state of the side mirror housing, and sets an imaging operation of the imaging section to a first power consumption mode in accordance with an ignition turn-off determination of the vehicle. The imaging section operates such that, when a motion of a surrounding object has been detected based on first image data generated in the first power consumption mode, the imaging operation is to be set to a second power consumption mode that is higher than the first power consumption mode.
