Vehicle Accessory Pairing Gateway for Secure In-Vehicle Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle user experience and control systems are limited to monitoring and controlling only built-in vehicle components and lack adequate security mechanisms to prevent unauthorized hardware and software interactions with the vehicle.
Innovation Solution
An in-vehicle control system with a vehicle accessory integration framework that allows seamless identification, authentication, authorization, integration, display, and control of vehicle accessories through a predetermined software requirements specification (SRS) and plug-and-play (PnP) ecosystem.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the in-vehicle control system allows any vehicle accessory to connect, then the adaptability and versatility of the system is improved, but the security and reliability of the vehicle is compromised
Solution Approach 1:
The system performs preliminary authentication and authorization checks before allowing accessory integration. The gateway module verifies accessory credentials and checks compatibility against a whitelist of approved accessories, preventing unauthorized devices from connecting to the vehicle's control system.
Solution Approach 2:
The gateway module acts as an intermediary between the accessory and the in-vehicle control system. It mediates the connection by authenticating the accessory, verifying its compatibility, and authorizing it to communicate with specific vehicle systems, thereby maintaining security while enabling versatility.
2Reliability
If the in-vehicle control system implements strict authentication and authorization protocols, then the security and reliability of the vehicle is improved, but the complexity of the system increases
Solution Approach 1:
The gateway module serves multiple functions within a single component: it authenticates accessories, authorizes communication, manages integration, and enforces security policies. This multi-functionality reduces the number of separate security components needed, thereby managing complexity while maintaining strong security protocols.
3Reliability
If the system performs comprehensive authentication and compatibility checks, then the reliability and security of accessory integration is improved, but the time required for pairing and integration increases
Solution Approach 1:
The system performs authentication and compatibility checks in advance during the pairing process, before the accessory is fully integrated. This preliminary verification ensures that only compatible and authorized accessories are integrated, maintaining reliability while completing the process efficiently.

AI summary
A control system for a vehicle may include one or more processors configured to execute instructions to receive, by one or more modules of the vehicle control system, a request to pair an accessory with the vehicle and determine, by the one or more modules of the vehicle control system, whether the accessory is preconfigured for pairing with the vehicle. In response to determining that the accessory is preconfigured for pairing with the vehicle, the one or more processors are configured to execute instructions to pair, by the one or more modules of the vehicle control system, the accessory with the vehicle and cause, by the one or more modules of the vehicle control system, a display of the vehicle to display a user interface customized for the accessory as paired with the vehicle.
