Vehicle Remote Debugging via Verified Cloud Tunnel Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle remote debugging methods lack security due to the potential for internal and external attacks through debugging links, especially when using intranet VPN techniques, and they require complex network environment handling and customized software development.
Innovation Solution
A vehicle remote diagnosis and debugging method and system that utilizes a cloud-side tunnel center to establish an intranet penetration tunnel, employing a vehicle-side debugging center and cloud-side debugging center for secure communication, with verification mechanisms like diagnosis debugging codes and tunnel connection codes, and an encryption mechanism to ensure security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If intranet VPN technique is used to establish debugging link, then remote debugging is enabled, but security is compromised due to potential internal and external attacks
Solution Approach 1:
The patent introduces a cloud-side tunnel center as an intermediary between the vehicle and external networks. This tunnel center establishes an intranet penetration tunnel that mediates all debugging communications, isolating the vehicle's internal network from direct external access while still enabling remote debugging functionality through the controlled tunnel connection.
Solution Approach 2:
The patent segments the debugging system into distinct components: vehicle-side debugging tools, cloud-side debugging center, and cloud-side tunnel center. This segmentation allows security functions to be separated from debugging functions, with the tunnel center handling security while debugging centers handle diagnostics, reducing the attack surface.
2Reliability
If customized software and private protocols are developed for each vehicle, then secure remote debugging is achieved, but development complexity and costs increase
Solution Approach 1:
The patent creates a universal cloud-side tunnel center that can serve multiple vehicles and debugging scenarios without requiring custom development for each vehicle. The tunnel center implements general security functions that work across different vehicle types, while vehicle-specific debugging protocols remain unchanged, reducing overall system complexity.
Solution Approach 2:
The vehicle-side debugging tools continue to use existing protocols and interfaces, maintaining their original functionality. The security infrastructure automatically establishes tunnels and manages connections without requiring custom software development on the vehicle side, allowing the vehicle system to serve itself while gaining enhanced security.

AI summary
The present application relates to the technical field of vehicle debugging, and discloses a vehicle remote diagnosis and debugging method and system. The method comprises: the vehicle sends information of a part to be debugged by a vehicle-side debugging center to a cloud-side debugging center, so that the cloud-side debugging center, in response to the information of the part to be debugged, requests tunnel connection information from a cloud-side tunnel center on a cloud platform; the vehicle receives the tunnel connection information returned by the cloud-side debugging center by the vehicle-side debugging center, forwards the tunnel connection information by the vehicle-side debugging center to a target part debugging center of the part to be debugged and the vehicle turns on a target vehicle-side tunnel client by the target part debugging center, and requests a debugging tunnel from the cloud-side tunnel center by the target vehicle-side tunnel client carrying the tunnel connection information, so that, after successfully verifying the tunnel connection information, the cloud-side tunnel center establishes the debugging tunnel; and the vehicle receives a remote debugging instruction sent by the cloud platform through the debugging tunnel. The present application solves the problem of low security of vehicle remote debugging under an intranet debugging condition.
