Vehicle Security Pairing via Mobile User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assigning a user to a motor vehicle, particularly as an owner, are inefficient and prone to misuse, often requiring manual input and lacking robust security measures.
Innovation Solution
A method utilizing existing communication connections between a mobile device and a motor vehicle's interaction device to securely establish a user's assignment to a security device, involving the transmission of unique identifications and authentication, ensuring automated and secure pairing without manual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual input methods are used for user assignment, then security can be maintained, but the assignment process becomes time-consuming and inefficient
Solution Approach 1:
The patent replaces manual input operations with automated electronic identification and authentication systems. The mobile device automatically transmits user identification data to the vehicle's control unit, which then performs automated authentication and assignment without requiring manual data entry or physical interaction beyond initiating the process.
Solution Approach 2:
The system enables self-service assignment where the mobile device autonomously completes the entire assignment process. The device automatically transmits identification data, receives authentication responses, and establishes the assignment relationship without requiring continuous user intervention or manual confirmation steps beyond the initial trigger.
2Ease of operation
If existing communication connections are utilized for assignment, then ease of operation is improved, but security risks from potential misuse increase
Solution Approach 1:
The control unit of the vehicle acts as an intermediary that receives communication from the mobile device but does not directly establish the assignment relationship. Instead, it forwards identification data to the external location for authentication, creating a security layer that separates the convenient communication channel from the critical assignment decision.
Solution Approach 2:
The system performs preliminary authentication of user identity before allowing assignment to occur. The external location verifies the user's identification data against authorized user records in advance of the assignment, ensuring that only pre-authorized users can be assigned to control the vehicle security functions.
3Productivity
If automated assignment is implemented, then productivity increases, but the complexity of the system architecture increases
Solution Approach 1:
The patent segments the assignment system into three distinct functional components: the mobile device for initiating assignment and providing identification, the vehicle's control unit for receiving communication and forwarding data, and the external location for authentication and decision-making. This segmentation allows each component to perform its function independently with well-defined interfaces.

AI summary
A method for establishing an assignment between a security device of a motor vehicle and a user of a mobile device, wherein the motor vehicle has an interaction device communicatively connected to the mobile device, includes the steps of transmitting a first identification assigned to the security device from the motor vehicle to the mobile device; deter-mining a second identification assigned to a user of the mobile device; transmitting the first and the second identification from the mobile device to an external location; determining that the first identification and the second identification are as-signed to the same motor vehicle; and transmitting a release of an assignment of the user of the mobile device to the security device.
