Vehicle Data Exchange via Portable Electronic Identifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for data exchange between a central data processing device and a vehicle-mounted data processing unit lack flexibility and security, particularly when multiple users share the same vehicle, as they do not allow users to easily set up their own accounts or change existing links, and fail to ensure convenient data access while maintaining high security.
Innovation Solution
A method involving a portable device with an electronic identifier that couples to the vehicle, allowing the creation of user accounts and establishing a secure connection between the vehicle's data processing unit and a central server, using a portable device as an ID card, with user accounts differentiated by unique input data, ensuring secure and convenient data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a connection is established between a user account in the motor vehicle and a user account on a central server via the telephone number of a mobile phone card permanently installed in the vehicle, then data exchange between the vehicle and central server is enabled, but the system lacks flexibility when multiple users share one vehicle as users cannot change or set up their own accounts
Solution Approach 1:
The system segments the account management by separating the permanent vehicle account from temporary user accounts. Each user can have their own account credentials stored in the portable device, allowing independent access without affecting the central vehicle-server connection. This segmentation enables multiple users to share the vehicle while maintaining individual account privacy and control.
Solution Approach 2:
The portable device (smartphone or tablet) acts as an intermediary between the user and the vehicle's data processing unit. It stores user account credentials and facilitates the connection process by providing authentication information to the vehicle system, thereby enabling flexible user access without requiring direct user-registration-complex-system interactions.
2Ease of operation
If user-specific data is stored on a server accessible via network connection, then data can be accessed from any location, but security risks increase with unauthorized access
Solution Approach 1:
The system performs preliminary authentication by verifying user credentials stored in the portable device before establishing any data connection. The vehicle's data processing unit checks the provided user identification and authorization data against stored information, and only after successful verification does it enable data exchange. This preliminary security check ensures that only authorized users can access the vehicle's data, even though the data is accessible via network connection.
3Adaptability or versatility
If a portable device with electronic identifier is used to couple to the vehicle for user identification, then user-specific data access is enabled, but the coupling process must be secure to prevent unauthorized access
Solution Approach 1:
The portable device serves multiple functions: it acts as an electronic identifier containing user credentials, as a communication interface between the user and vehicle system, and as a secure storage medium for account information. The vehicle's data processing unit is designed to universally accept different types of portable devices (smartphones, tablets) that meet the authentication requirements, thereby enabling flexible user identification without requiring device-specific complex coupling mechanisms.

AI summary
The method involves providing a portable device in which a readable electronic identification is stored. A unit is provided for coupling the portable device with the vehicle. The readable electronic identification is communicated to the latter data processing unit by coupling the portable device with the vehicle. The possibility of executing a user node in the latter data processing unit is created. A central data processing unit coupled to the network is provided in which user nodes are guided. An independent claim is included for a vehicle with a unit for reading an electronic identification from the coupled portable device into the data processing unit.
