Telematics Voice Diagnostic Reporting for Drivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle diagnostic systems provide limited information to drivers about the severity of issues and do not offer clear guidance on corrective actions, relying on technical trouble codes that require technical expertise to interpret, and existing solutions require direct physical connection to the vehicle for data extraction.
Innovation Solution
A diagnostic test and reporting method using a telematics unit that communicates with the onboard diagnostic system, allowing drivers to request tests via a user interface, receive pre-recorded voice messages about diagnostic status and corrective actions, and optionally connect with a live advisor for further assistance through a wireless connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If pre-recorded voice messages are used to provide diagnostic information, then driver understanding is enhanced and attention diversion is reduced, but system complexity increases
Solution Approach 1:
Pre-recorded voice messages are prepared in advance for various diagnostic scenarios and stored in the telematics unit. When a diagnostic trouble code is detected, the system retrieves and plays the corresponding pre-prepared voice message, eliminating the need for complex real-time natural language generation while enhancing driver understanding.
2Ease of operation
If live advisor communication is provided for diagnostic assistance, then comprehensive guidance is available, but communication costs and call center burdens increase
Solution Approach 1:
The system enables drivers to obtain diagnostic information and corrective action guidance through pre-recorded voice messages that are automatically played based on detected trouble codes. This self-service approach provides comprehensive guidance without requiring live advisor intervention, significantly reducing communication costs and call center burdens.
Solution Approach 2:
The telematics unit acts as an intermediary between the diagnostic system and the driver, translating technical trouble codes into user-friendly voice messages. This intermediary function provides comprehensive guidance while eliminating the need for expensive live communication infrastructure.
3Loss of information
If diagnostic information is provided through textual display, then additional information is available to drivers, but visual attention must be diverted from the road
Solution Approach 1:
The system replaces visual textual display with auditory voice messages delivered through the vehicle's audio system. This substitution allows drivers to receive comprehensive diagnostic information through their sense of hearing while keeping their visual attention on the road, thereby eliminating the safety risk associated with visual distraction.
4Quantity of substance
If trouble codes are displayed without interpretation, then diagnostic data is provided, but drivers cannot understand or act on the information
Solution Approach 1:
The system transforms the parameter of information presentation from technical trouble codes to natural language voice messages. This parameter change maintains the complete diagnostic data while fundamentally improving understandability and usability for drivers, enabling them to comprehend and take appropriate actions based on the diagnostic information.
Data Source
AI summary
A system and method for providing user-initiated vehicle diagnostic testing and reporting in a telematics-enabled vehicle. In the method, a request for a vehicle diagnostic test is received from the driver through a user interface of a telematics unit on the vehicle. A simplified initial diagnostic check is made and a first voice message is played for the driver that provides information concerning any detected vehicle problem. The method then undergoes a more complete diagnostic check and the resulting diagnostic information is used to select and play a second voice message that provides instructions for taking corrective action to fix the detected problem. Communication with a live advisor is also provided by way of a cellular or other wireless carrier system.
