Vehicle Charging Lock Release Control Under Connector Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to effectively manage vehicle immobilization states when external charging is performed using automatic charging devices, particularly when issues arise with the charging device during the charging process, leading to potential inability to release the immobilization state.
Innovation Solution
A vehicle control device that monitors connection status, user requests, and obstacle presence to autonomously release the immobilization state when conditions are met, ensuring safe movement resumption even if the automatic charging device encounters trouble.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle is controlled to prohibit movement when receiving an instruction signal from an automatic charging device, then safety during charging is improved, but the vehicle cannot be released from immobilization when the charging device encounters trouble
Solution Approach 1:
The control device preliminarily establishes multiple release conditions (charging connector disconnection, obstacle absence, user request) that must be satisfied before releasing immobilization. This preliminary setup ensures safety while enabling release when conditions are met, even if the charging device encounters trouble.
Solution Approach 2:
The control device acts as an intermediary between the automatic charging device and the vehicle movement control. It independently evaluates release conditions and makes the final decision on immobilization release, rather than simply following commands from the charging device. This intermediary role prevents stuck immobilization when the charging device fails.
2Object-affected harmful factors
If the vehicle prohibits movement during automatic charging, then accidental starting is prevented, but user flexibility and emergency response are reduced
Solution Approach 1:
The immobilization state is made dynamic rather than static. The control device continuously monitors release conditions and can transition from immobilized to movable state when conditions are satisfied. This dynamic approach maintains safety during charging while allowing flexible user control when appropriate conditions exist.
Solution Approach 2:
The control device implements feedback by continuously monitoring the state of release conditions (connector connection status, obstacle detection, user requests) and automatically adjusting the vehicle's movement prohibition accordingly. This feedback mechanism balances safety prevention with user flexibility.

AI summary
A vehicle control device mounted on a vehicle capable of external charging, the vehicle control device being configured to: control to cause a state of the vehicle to a first state, in which a movement of the vehicle is prohibited, when receiving an instruction signal from an automatic charging device, which automatically connects a charging connector to a charging port; and release the first state under all of the following conditions are satisfied: a) there is a request for releasing the first state by a user of the vehicle while the vehicle is controlled under the first state, b) the charging connector is not connected to the charging port, and c) there is no obstacle in a traveling direction of the vehicle.
