Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diagnostic systems for vehicles lack an efficient method to test and diagnose connected services such as WiFi, BLUETOOTH, and storage media services, which are essential for ensuring the proper functioning of in-vehicle communication and entertainment systems.
Innovation Solution
A diagnostic system and method that utilizes a connected services diagnostic computer or computer program product to establish communication with a vehicle computing system, transmit diagnostic data to a diagnostics server, and determine the status of connected services, including the cause and location of failures, using a handheld device with LED indicators for output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a diagnostic system is implemented to test connected services in vehicles, then the reliability of communication and entertainment systems is improved, but the device complexity increases
Solution Approach 1:
The diagnostic computer is designed as a universal tool that can test multiple connected services (WiFi, BLUETOOTH, storage media, audio) through a single integrated interface. The system uses a standardized communication protocol that works across different vehicle models and service types, eliminating the need for separate diagnostic tools for each service while maintaining comprehensive coverage.
Solution Approach 2:
The system introduces a diagnostics server as an intermediary component that receives diagnostic data from the vehicle computing system and processes the results. This server acts as a mediator between the diagnostic computer and the vehicle's complex communication systems, simplifying the diagnostic process by centralizing data processing and result analysis in a dedicated component.
2Measurement precision
If comprehensive diagnostic testing of connected services is performed, then the measurement precision of service status is improved, but the loss of time increases
Solution Approach 1:
The diagnostic system performs preliminary actions by automatically establishing communication protocols and initiating service tests before the actual diagnostic process begins. The system pre-configures test parameters and communication channels, so when diagnostic testing starts, the infrastructure is already in place, reducing the time required for setup and enabling more comprehensive testing without proportional time increases.
Solution Approach 2:
The system implements feedback mechanisms that provide real-time status information during diagnostic testing. The diagnostic computer receives immediate feedback from the vehicle computing system about service status, allowing the system to identify and report issues quickly without requiring exhaustive manual checking of each service parameter, thus maintaining high measurement precision while minimizing testing time.
Data Source
AI summary
Various embodiments include tools and methods for diagnosing connected services in a vehicle. Communication with a vehicle computing system in a vehicle may be established. A diagnostic connection to a diagnostics server may also be established. Vehicle information and diagnostic data from one or more connected services may be received from the vehicle computing system and transmitted via a diagnostic connection to the diagnostics server. A connected services diagnostic status for the vehicle may be determined based on the vehicle information and the diagnostic data. The connected services diagnostic status may be received from the server and output to a user.
