Vehicle Door Authentication via Design Cover Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In smart entry systems, high-speed operation of the operating member can lead to premature latch release before user authentication is complete, resulting in the need for additional operations to open the door.
Innovation Solution
A vehicle door open/close operation apparatus that includes a design cover with a detection switch to initiate user authentication upon opening, an electric actuator for latch release, and a control unit to ensure authentication is completed before allowing latch release, thereby preventing the need for repeated operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authentication is carried out after detecting operation of the operating member, then security is maintained, but the door cannot be opened smoothly when the operating member is operated quickly
Solution Approach 1:
The detection switch detects displacement of the design cover from the closed position toward the open position and triggers user authentication before the operating member operation is completed. This preliminary authentication action ensures that authentication is finished before latch release is enabled, preventing the need for repeated operations even when the operating member is operated quickly.
2Loss of time
If the detection switch detects displacement of the design cover to trigger authentication, then authentication timing is improved, but the device complexity increases
Solution Approach 1:
The detection switch serves multiple functions: it detects both the opening of the design cover and triggers the user authentication process. By making this single component multi-functional, the patent avoids adding separate detection mechanisms, thereby minimizing the increase in device complexity while achieving timely authentication.
3Ease of operation
If latch release is enabled immediately upon operating member operation, then ease of operation is improved, but premature latch release occurs before authentication
Solution Approach 1:
The control unit continuously monitors the authentication state and uses this feedback to control when latch release is enabled. Latch release is only enabled after user authentication is successfully completed, ensuring that the door can be opened easily by legitimate users while preventing premature latch release before authentication.

AI summary
A vehicle door open/close operation apparatus is provided in which a design cover can be opened by a manual operation and can close at least part of an opening provided in a door, and a latch release is operated by a latch device due to the operation of an operating member in a state in which the design cover is open, wherein displacement of the design cover (24) from a closed position toward an open position is detected by a detection switch (26), and a control unit carries out the user authentication in response to detection of displacement of the design cover (24) by the detection switch (26). This enables the necessity for carrying out an operation of the operating member again to be avoided even if the operating member is operated quickly, thus enabling the door to be opened smoothly.
