Vehicle Coded Lock Password Reset via NFC Card Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process of unlocking a vehicle-mounted coded lock by inputting a password through a central control screen is inefficient and cumbersome, requiring users to drive to a vehicle maintenance shop or use an after-sales diagnostic instrument when the password is forgotten, leading to delays and increased complexity.
Innovation Solution
A method using a card reader to obtain near field communication information from a near field communication card, determine a verification result based on a target identification, and clear the pre-stored correct password to unlock the coded lock, utilizing a vehicle-mounted host to facilitate password clearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user drives to a vehicle maintenance shop or uses an after-sales diagnostic instrument to clear the password, then the password can be cleared, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The system enables the user to clear their own password using a near field communication card and card reader within the vehicle, without needing external assistance from maintenance shops or diagnostic instruments. The user simply places the card on the card reader and follows the on-screen instructions to complete the password clearing process independently.
Solution Approach 2:
A near field communication card is introduced as an intermediary object that stores identification information and enables the user to authenticate and clear their password. The card reader acts as another intermediary that reads the card information and transmits it to the vehicle-mounted host for verification and password clearing.
2Reliability
If the user drives to a vehicle maintenance shop to clear the password, then the password can be cleared, but time is lost and efficiency is reduced
Solution Approach 1:
The user's identification information is pre-stored in a near field communication card before the password locking incident occurs. This preliminary preparation allows the user to quickly clear their password by simply presenting the pre-prepared card, without needing to travel to a maintenance shop or use complex diagnostic procedures.
Solution Approach 2:
The manual process of driving to a maintenance shop and using physical diagnostic instruments is replaced by an automated electronic system. The near field communication card and card reader enable automatic authentication and password clearing through electromagnetic communication, eliminating the need for mechanical travel and manual diagnostic operations.
3Reliability
If the user drives to a vehicle maintenance shop or uses diagnostic instruments, then the password can be cleared, but the process complexity increases
Solution Approach 1:
The password clearing functionality is extracted from the complex external diagnostic instruments and maintenance shop procedures, and integrated into the vehicle's own system. The near field communication card contains only the necessary identification information, and the card reader performs only the essential function of reading and transmitting this information, simplifying the overall process.
Solution Approach 2:
The near field communication card serves multiple functions: it stores user identification information, acts as an authentication credential, and enables password clearing. The card reader also performs multiple functions including reading the card, transmitting information to the host, and controlling the unlocking process. This multi-functionality reduces the need for separate specialized devices and procedures.

AI summary
The present application provides a method for clearing a password of a vehicle-mounted coded lock, an apparatus, a device and a storage medium. The method includes: activating a card reader in response to a user triggering a password-forgotten component; obtaining first near field communication information, where the first near field communication information is information pre-stored inside a first near field communication card and then collected by the card reader, the first near field communication information includes a first target identification corresponding to the first near field communication card, and the first near field communication card belongs to a target near field communication card; determining a first verification result of the first near field communication card based on the first target identification; clearing a pre-stored correct password corresponding to the coded lock based on the first verification result being verification passed, and unlocking the coded lock, where the coded lock is mounted on a vehicle. The present application can improve unlocking efficiency and reduce unlocking complexity.
