Vehicle Camping Mode Power Control for Battery Discharge Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During car camping, vehicle batteries often discharge due to continuous power consumption of unnecessary vehicle functions, leading to inconvenience and mobility issues.
Innovation Solution
A vehicle power management apparatus that sets a power management mode to 'camping mode' based on battery state of charge, allowing essential functions while limiting non-essential ones, and automatically switching to a power-saving mode when the battery level falls below a threshold, thereby preventing battery discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all vehicle functions are allowed to operate during car camping, then user convenience and comfort are improved, but battery power is consumed excessively leading to discharge
Solution Approach 1:
The system dynamically adjusts vehicle function operations based on camping mode detection and battery SOC levels. Essential functions remain operable while non-essential functions are limited, creating a dynamic balance between user convenience and power conservation
Solution Approach 2:
The system changes operational parameters of vehicle functions based on detected conditions. When camping mode is detected and SOC is sufficient, essential functions operate normally; when SOC drops below threshold, the system changes parameters to limit non-essential functions and switch to power-saving mode
2Use of energy by moving object
If non-essential vehicle functions are limited during camping mode, then battery power consumption is reduced, but user convenience is degraded
Solution Approach 1:
The system applies different operational qualities to different vehicle functions based on their essentiality. Essential functions (lighting, door unlocking) maintain full operational quality, while non-essential functions (automatic tailgate, seat adjustments) have their operations limited or disabled in camping mode
Solution Approach 2:
The system dynamically adjusts the level of function limitation based on real-time battery SOC monitoring. When SOC is above threshold, more functions remain available; when SOC drops, the system dynamically switches to power-saving mode with stricter limitations
3Reliability
If the system monitors battery SOC continuously and switches modes, then battery discharge is prevented, but system complexity increases
Solution Approach 1:
The system implements continuous feedback monitoring of battery SOC levels and uses this information to automatically switch between camping mode and power-saving mode. The feedback loop ensures reliable battery discharge prevention through real-time condition assessment and mode adjustment
Solution Approach 2:
The power management system operates autonomously by automatically detecting camping mode, monitoring battery SOC, and switching between operational modes without user intervention. The system serves itself by managing power distribution and function limitations based on detected conditions

AI summary
An embodiment vehicle power management apparatus includes a memory configured to store a threshold state of charge (SOC) and a processing device functionally connected with the memory, wherein the processing device is configured to set a power management mode to a camping mode, identify a battery SOC, identify whether the battery SOC is greater than or equal to the threshold SOC, and enter the camping mode to allow an operation of a first vehicle function and limit an operation of a second vehicle function in response to the battery SOC being greater than or equal to the threshold SOC.
