Vehicle Dark Current Controller Automatic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dark current controllers require manual mode switching from pre-delivery to post-delivery, leading to potential customer discomfort and reduced vehicle reliability due to forgotten mode settings.
Innovation Solution
A system and method that automatically switch the dark current mode from manufacturer management to customer management without a physical switch, using a dark current controller with a storage device for customer address information, navigation for location tracking, and start detection to determine mode changes based on vehicle usage and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a physical mode switch is used for manual mode switching, then the dark current controller can be operated, but the circuit size increases and driver convenience deteriorates
Solution Approach 1:
The patent replaces the mechanical physical mode switch with an electronic control system. The dark current controller uses electronic signals and software logic to switch between pre-delivery mode and post-delivery mode, eliminating the need for a physical switch. This substitution reduces circuit complexity and improves ease of operation while maintaining the mode switching functionality.
2Reliability
If manual mode switching is required, then the dark current controller can be operated, but the reliability deteriorates due to forgotten mode settings
Solution Approach 1:
The patent implements self-service functionality where the dark current controller automatically determines and switches between modes based on stored delivery information. The system checks whether delivery has been completed and automatically transitions from pre-delivery mode to post-delivery mode without requiring manual intervention from the driver, thereby improving reliability while maintaining operational simplicity.
Solution Approach 2:
The patent uses feedback mechanisms where the dark current controller continuously monitors the delivery status and automatically adjusts the mode accordingly. The system receives feedback about whether delivery has been completed and uses this information to automatically switch modes, eliminating the need for manual mode setting and preventing reliability issues associated with forgotten mode changes.
3Reliability
If the mode switch is kept in OFF state, then the dark current is interrupted, but the convenience functions do not operate normally causing customer discomfort
Solution Approach 1:
The patent implements dynamic mode switching where the dark current controller automatically transitions between pre-delivery mode (interrupting dark current) and post-delivery mode (enabling dark current) based on delivery status. This dynamic adjustment ensures that convenience functions receive appropriate power supply after delivery, eliminating customer discomfort while maintaining battery protection during the pre-delivery period.

AI summary
A system for controlling a dark current of a vehicle includes: a storage device storing address information of a customer; a navigation device acquiring current location information of a vehicle; a start detection device detecting a start of the vehicle to acquire start information; and a dark current controller determining whether to switch an initially set operation mode based on the address information, the current location information, and the start information. A method for controlling a dark current of the vehicle includes: storing the address information; acquiring the current location information; acquiring the start information; and determining whether to switch an initially set operation mode based on the address information, the current location information, and the start information.
