EV Charging Lid Notification System Suppressing Alerts During Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle notification systems for open lid members are inefficient, as they often provide unnecessary alerts, leading to user annoyance and decreased effectiveness, especially when the lid is deformed or the mechanism is temporarily non-functional.
Innovation Solution
A vehicle system that suspends notifications when the driving energy supply device is connected to the interface, reducing unnecessary alerts and enhancing notification effectiveness by changing notification modes based on vehicle speed and operational states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous notification is provided when the lid member is in the open state, then the user is notified of the open state, but the notification becomes annoying and less effective over time
Solution Approach 1:
The notification system dynamically adjusts its behavior based on the connection state of the driving energy supply device. When connected, notifications are suspended; when disconnected, notifications are activated. This dynamic adaptation resolves the contradiction by making the notification system responsive to operational context, maintaining effectiveness without causing continuous annoyance.
Solution Approach 2:
The system changes the notification parameter (active/inactive state) based on the connection status of the external power supply. This parameter change allows the system to provide notifications only when necessary (when the charger is disconnected and the lid should be closed), thereby maintaining notification effectiveness while avoiding unnecessary user annoyance.
2Reliability
If notification is provided when the lid member is open, then safety is improved, but unnecessary notifications occur when the vehicle is being charged
Solution Approach 1:
The notification relevance is optimized by changing the notification parameter based on the charging state. When the driving energy supply device is connected, the notification parameter is set to inactive, avoiding irrelevant notifications. When disconnected, it is activated to ensure safety-critical notifications are provided, thus preventing loss of relevant information while filtering out unnecessary alerts.
Solution Approach 2:
The connection state of the driving energy supply device acts as an intermediary condition that mediates between the lid open state and the notification output. This intermediary mechanism ensures that notifications are only provided when both the lid is open and the charger is disconnected, thereby maintaining safety while eliminating irrelevant notifications during charging operations.
3Object-affected harmful factors
If the lid member covers the interface, then protection is improved, but access for charging is hindered
Solution Approach 1:
The lid member dynamically changes its position between closed (protecting the interface) and open (allowing charging access) states based on operational requirements. This dynamic behavior resolves the contradiction by providing protection when needed and access when required, without compromising either function.
Solution Approach 2:
The lid member is extracted from the closed position during charging operations to provide access to the interface, and then returned to the closed position to restore protection. This extraction and restoration mechanism allows the system to temporarily remove the protective barrier when access is needed, thereby resolving the contradiction between protection and accessibility.

AI summary
A vehicle performs notification about an open/closed state of a lid member covering an interface for supplying driving energy. The vehicle includes a notification portion that performs notification when the lid member is in the open state and a connection detecting portion that detects a connection state of a driving energy supply device to the interface. In the vehicle, the notification portion suspends notification when the driving energy supply device is connected to the interface during the open state of the lid member.
