Vehicle Mobile Device Auto-Unlock via ID Code Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when frequently entering a personal identification code to unlock mobile devices in vehicles, and there is a risk of theft if the code is forgotten.
Innovation Solution
A method where the mobile device is coupled to the vehicle using a vehicle identification code stored in the vehicle's memory, which is transmitted to the mobile device to unlock it, eliminating the need for a personal identification code each time, with a secondary personal identification code as a secondary security measure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a personal identification code is used to unlock the mobile device, then the device security against theft is improved, but the ease of operation deteriorates because the user must enter the code every time
Solution Approach 1:
The system performs preliminary authentication by comparing the vehicle identification code with the unlocking code stored in the mobile device before requiring user input. This preliminary check automatically unlocks the device when the vehicle is detected, eliminating the need for repeated code entry while maintaining security through the pre-stored authentication credentials.
Solution Approach 2:
The vehicle identification code serves as an intermediary element that mediates between the vehicle's security system and the mobile device's locking mechanism. Instead of directly using the personal identification code, the system introduces the vehicle-specific ID as a intermediary authentication factor that triggers automatic unlocking when matched with the stored unlocking code.
2Ease of operation
If the mobile device is always unlocked for convenience, then the ease of operation is improved, but the risk of theft increases
Solution Approach 1:
The unlocking functionality is activated locally and specifically within the vehicle environment. The device remains locked when outside the vehicle but automatically unlocks when detected inside, creating location-specific access control. This localized unlocking behavior provides convenient access when needed while maintaining security when the device is outside the protected environment.
3Ease of operation
If geographic position-based unlocking is implemented, then the ease of operation is improved by eliminating code entry, but the device complexity increases
Solution Approach 1:
The mobile device leverages its existing universal capabilities (data connection, code storage, comparison functions) to implement the unlocking system. Instead of requiring specialized geographic positioning hardware or complex location-based authentication mechanisms, the system uses the device's universal data processing and code comparison abilities already present in standard mobile devices, thereby avoiding increased device complexity.

AI summary
The invention relates to a method for communicating data in a vehicle (1) between a vehicle-mounted data communication device (2) and a mobile device (8). In said method, the mobile device (8) is coupled to the vehicle (1) in a locked state, the vehicle-mounted data communication device (2) transmits a vehicle identification code stored in a non-modifiable manner in a memory (20) of the vehicle (1) to the mobile device (8) where the transmitted vehicle identification code is compared with an unlocking code securely stored in the mobile device (8), and if the compared codes match, the mobile device (8) is unlocked. The invention further relates to a system for operating a mobile device (8) in a vehicle (1), said vehicle (1) comprising a vehicle-mounted data communication device (2) for communicating data with the mobile device (8) as well as a memory (20) in which a vehicle identification code is stored in a non-modifiable manner, and the mobile device (8) comprising a locking device (21) in which an unlocking code is securely stored. The system is characterized in that vehicle-mounted data communication device (2) can transmit the vehicle identification code stored in the memory (20) of the vehicle (1) to the mobile device (8), and the transmitted vehicle identification code can be compared, in the locking device (21) of the mobile device (8), with the unlocking code stored in the unlocking device, and if the compared codes match, the mobile device can be unlocked.
