Smart Key Door Lock Control During Vehicle Start State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle control systems require redundant buttons for locking and unlocking doors on both the smart key and the armrest, increasing costs and user operation difficulty, and do not allow keyless entry when the vehicle is started.
Innovation Solution
A control apparatus and method that utilize a smart key to substitute for the door locking and unlocking button on the armrest, allowing the smart key to transmit control signals for locking or unlocking the door when the vehicle is in a started state, and using a smart key check module and door control module to manage these functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If door locking and unlocking buttons are provided on both the smart key and the armrest of the door trim, then the user can operate door locking/unlocking from multiple positions, but the cost of the vehicle increases and operation difficulty increases due to redundant functions
Solution Approach 1:
The patent extracts the door locking and unlocking button from the armrest of the door trim, retaining only the smart key with these functions. This eliminates the redundant button on the armrest while preserving the core functionality of door locking/unlocking through the smart key.
2Ease of operation
If the vehicle can receive control signals for locking or unlocking doors only when the vehicle is in a turned-off state, then the system is simple to control, but the user cannot use the smart key after starting the vehicle, increasing the possibility of losing the smart key
Solution Approach 1:
The patent introduces dynamic control that adapts the smart key's functionality based on the vehicle's state. When the vehicle is started, the system dynamically adjusts to allow door locking/unlocking operations through the smart key, creating a flexible system that responds to changing conditions rather than maintaining a fixed restriction.
Solution Approach 2:
The system incorporates feedback mechanisms to monitor the smart key's presence and the vehicle's operational state, adjusting the allowed functions accordingly. This feedback loop enables the system to maintain security while permitting necessary operations during vehicle operation.
3Ease of manufacture
If there is no place to keep the smart key in shared or rental cars, then the vehicle sharing system is simple, but the user cannot find the smart key after driving
Solution Approach 1:
The patent implements a nested structure where the smart key is placed within a designated storage compartment or groove in the vehicle interior. This nesting approach provides a fixed, organized location for the smart key that is integrated into the vehicle's structure, making it easy to locate and retrieve while maintaining system simplicity.

AI summary
A control apparatus and a method for locking or unlocking a door include a smart key including a door locking and unlocking button provided thereon and configured for transmitting a control signal for locking or unlocking the door through a door locking and unlocking button; a smart key check module configured to determine whether the smart key is in a vehicle; and a door control module configured to determine whether the vehicle is in a started state or a turned-off state, determine whether to receive a control signal for locking or unlocking the door from the smart key according to a result of the determining whether the smart key is in the vehicle when the vehicle is in the started state, and control a corresponding door of the vehicle when receiving the control signal for locking or unlocking the door from the smart key.
