Wireless Vehicle Servicing Gateway for Remote Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless vehicle diagnostics systems lack a standardized and secure method for remote vehicle servicing, including diagnostics, software updates, and key reprogramming, which limits efficient and authorized remote maintenance.
Innovation Solution
A computer-implemented method and system for remote vehicle servicing that uses a servicing terminal to receive instructions, generate and transmit servicing request data packets over compatible communication channels (like BLUETOOTH, cellular, or 802.11) to a vehicle computing system, adhering to standards such as J-2534, and presents servicing status information audibly, textually, or visually, with authorization validation onboard or offboard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication channels are used for remote vehicle servicing, then the need for physical vehicle presence is reduced, but communication compatibility and security challenges arise
Solution Approach 1:
The patent introduces a gateway as an intermediary device that mediates communication between the servicing terminal and vehicle modules. The gateway receives servicing requests from various communication channels (Bluetooth, cellular, 802.11), validates authorization, and translates requests into standardized vehicle communication protocols, thereby resolving compatibility issues without compromising ease of operation
Solution Approach 2:
The system dynamically changes communication parameters by selecting different wireless protocols based on the specific vehicle and servicing requirements. The gateway can adapt communication modes, data formats, and security protocols to match the target vehicle's specifications, enabling versatile remote access while maintaining system compatibility
2Adaptability or versatility
If standardized servicing protocols are implemented, then interoperability improves, but implementation complexity increases
Solution Approach 1:
The gateway is designed as a universal device that can handle multiple servicing standards and protocols simultaneously. It provides multi-functional capabilities to support different vehicle makes, models, and communication protocols through a single platform, achieving broad adaptability without requiring separate systems for each standard
Solution Approach 2:
The system implements automated authorization validation and protocol selection mechanisms that operate without manual intervention. The gateway automatically determines the appropriate servicing protocol based on vehicle identification, validates authorization credentials, and configures communication parameters autonomously, reducing the complexity burden on users
3Reliability
If authorization validation is performed onboard the vehicle, then security is enhanced, but processing time increases
Solution Approach 1:
The system performs preliminary authorization validation by pre-registering servicing credentials and vehicle identification data before actual servicing operations. Authorization tokens are cached and validated locally at the gateway, enabling rapid authentication during servicing without requiring real-time onboard processing for each operation
Solution Approach 2:
The system implements a feedback mechanism where authorization decisions and validation results are communicated between the gateway and vehicle computing system. The gateway receives confirmation of authorization status and can adjust subsequent communication based on this feedback, optimizing the balance between security verification and processing efficiency
Data Source
AI summary
Various embodiments include methods, systems, and computer-program products for wireless vehicle servicing. Instructions for performing a vehicle servicing operation may be received at a servicing terminal. Further, vehicle servicing operation data based on the instructions and data communication rules for communicating data to a vehicle computing system may be received. Servicing request data stored in computer-readable media may be generated and may include the vehicle servicing operation data and the one or more data communication rules. The servicing request data may be transmitted to the vehicle computing system and servicing return data may be received. Servicing status information may be presented on the servicing terminal based on the servicing return data.
