Vehicle Module Pairing via BLE Authentication Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for pairing a mobile device with a vehicle's electronic module are tedious and time-consuming, particularly in scenarios like renting a vehicle where users may not have the time or desire to manually register and configure Bluetooth or wifi connections.
Innovation Solution
A method that facilitates pairing by exchanging identification codes between the mobile device and the vehicle's electronic module, allowing for automatic activation of different communication modes (e.g., BLE to Bluetooth or wifi) during initial authentication, eliminating the need for manual configuration and ensuring secure temporary key usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual registration and configuration of Bluetooth or wifi identification codes is performed, then secure communication between mobile device and vehicle module is achieved, but the pairing process becomes tedious and time-consuming
Solution Approach 1:
The system performs preliminary authentication using BLE to establish trust between devices before automatically configuring the second communication mode. The mobile device and vehicle module exchange and verify identification codes through BLE in advance, so that when Bluetooth or wifi connection is needed, the pairing is already complete and secure communication is established without manual intervention.
2Ease of operation
If automatic activation of second communication mode is implemented, then user convenience is improved, but security risks may increase due to automated processes
Solution Approach 1:
BLE serves as an intermediary authentication channel between the mobile device and vehicle module. The BLE connection acts as a trusted mediator that verifies identification codes and establishes authentication before enabling the second communication mode (Bluetooth or wifi). This intermediary step ensures that even though the process is automated, security is maintained through verified authentication.
3Reliability
If temporary identification keys are used for rental vehicles, then security against unauthorized access is improved, but the complexity of key management increases
Solution Approach 1:
The system uses temporary identification keys that are valid only for the duration of the rental period and are automatically invalidated when the rental ends. These disposable authentication credentials are generated specifically for rental scenarios, allowing secure access during the rental period while automatically preventing unauthorized access after return, without requiring complex manual key management by the user.

AI summary
The present invention relates essentially to a pairing method between a mobile device (SP) and an electronic module (M) of a vehicle (V), said method including an initial authentication step (200) for authenticating the mobile device (SP) with the electronic module (M) of the vehicle (V), the initial authentication step (200) being carried out according to a first communication mode, characterised in that the method comprises a step (210) which consists of exchanging, according to the first communication mode, between the mobile device (SP) and the electronic module (M) of the vehicle (V), a first identification code and a second identification code associated with the mobile device (SP) and the electronic module (M) of the vehicle (V), respectively, the first identification code and the second identification code authorising the mobile device (SP) and the electronic module (M) of the vehicle (V) to communicate with one another according to a second communication mode, the second communication mode being different from the first communication mode.
