Cloud-Managed Vehicle Diagnostic Permissions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the ability to offload vehicle data via a mobile device without a dedicated diagnostic application, resulting in missed opportunities for data collection from existing device-to-vehicle interactions.
Innovation Solution
A system that utilizes a cloud server to manage application permissions and send diagnostic requests to vehicles through a vehicle-enabled mobile application, allowing for the collection of diagnostic data via an existing communication channel without the need for a specific diagnostic app on the mobile device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated diagnostic application is installed on the mobile device, then diagnostic data can be collected from the vehicle, but the system complexity increases and user convenience decreases
Solution Approach 1:
The mobile application is designed to perform multiple functions: it serves as both a general vehicle control application and a diagnostic data collection tool. The cloud server automatically manages diagnostic requests and data retrieval, eliminating the need for a separate dedicated diagnostic application while maintaining diagnostic capabilities through the universal vehicle control app.
Solution Approach 2:
The system enables self-service diagnostic data collection where the cloud server automatically sends diagnostic requests to the vehicle and retrieves results without requiring user intervention to install or configure specialized diagnostic software. The existing application permissions infrastructure is leveraged to automatically facilitate data offload.
2Loss of information
If application permissions are expanded to allow data access, then diagnostic data can be retrieved, but user privacy concerns increase
Solution Approach 1:
The cloud server acts as an intermediary between the mobile application and the vehicle systems. It manages application permissions and controls data access, retrieving only necessary diagnostic information while preventing unauthorized access to sensitive user data. This intermediary layer protects user privacy by filtering and managing what data is accessed and how it is used.
Solution Approach 2:
The system implements granular permission control where specific diagnostic data access rights are granted locally to the application based on its identity and purpose. Rather than broad permission grants, the cloud server configures precise permission sets that allow only the necessary diagnostic data to be accessed, maintaining user privacy while enabling functional requirements.
3Adaptability or versatility
If third-party applications are allowed to integrate with the vehicle, then application versatility increases, but security risks and unauthorized data access increase
Solution Approach 1:
The cloud server provides universal permission management that works across all third-party applications regardless of their specific function. By creating a standardized permission framework that serves multiple applications and purposes, the system enables versatile integration while maintaining consistent security controls through centralized permission configuration and validation.
Data Source
AI summary
A processor of a vehicle is programmed to send a message to a mobile device connected to the processor to request an application permissions update for the vehicle from a remote server, responsive to the vehicle lacking application permissions for a vehicle-enabled mobile application executed by a mobile device. The processor is further programmed to receive, from the server, the application permissions update including both the application permissions and a diagnostic request to receive data from the vehicle.
