Vehicle Diagnostic Alert System Using Severity Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle diagnostic systems do not effectively notify vehicle owners of severe vehicle conditions, leading to potential unrecoverable problems and increased warranty costs due to delayed issue resolution.
Innovation Solution
A system that associates a cellular telephone with a vehicle's identification number, receives diagnostic information, and automatically transmits text message alerts to the owner if severity thresholds are exceeded, using wireless communication via BLUETOOTH or cellular networks, with optional instructions and hyperlinks for further vehicle health reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle diagnostic systems continuously monitor and transmit data, then vehicle condition awareness is improved, but energy consumption and system complexity increase
Solution Approach 1:
The system applies different monitoring thresholds and notification methods to different vehicle conditions. Critical issues trigger immediate alerts, while minor conditions are monitored without constant notification, optimizing resource usage while maintaining reliability.
Solution Approach 2:
The system changes monitoring parameters dynamically based on vehicle operation state. During normal operation, monitoring intensity is reduced to save energy, while during critical conditions or specific driving patterns, monitoring intensity increases to ensure safety.
2Reliability
If severe vehicle conditions are detected and alerts are sent immediately, then vehicle reliability is improved, but false alarms and owner anxiety increase
Solution Approach 1:
The system performs preliminary analysis of diagnostic data before triggering alerts. Multiple data points are evaluated together, and trends are analyzed to confirm genuine issues before sending notifications, reducing false alarms while maintaining early detection capability.
Solution Approach 2:
The system incorporates feedback mechanisms where alert history and vehicle response to previous alerts are considered. If similar conditions occur repeatedly without resolution, the system adjusts its alerting behavior to reduce false positives while maintaining sensitivity to genuine problems.
3Measurement precision
If comprehensive diagnostic data is collected and transmitted, then diagnostic accuracy is improved, but data transmission time and network usage increase
Solution Approach 1:
The system extracts and transmits only the most relevant diagnostic data points based on pre-defined criteria and current vehicle conditions. Non-critical data is filtered out or stored locally, reducing transmission time while maintaining diagnostic accuracy for important parameters.
Solution Approach 2:
Diagnostic data is segmented into priority levels, with critical data transmitted immediately, important data transmitted during appropriate windows, and routine data stored for periodic upload. This segmentation optimizes transmission timing and reduces overall transmission time.

AI summary
One aspect includes a system for monitoring a vehicle's health status. The system comprises a vehicle monitoring computer system configured to (1) receive information associating a cell phone with a vehicle, (2) receive vehicle diagnostic information including vehicle conditions, (3) automatically determine a severity status for the vehicle conditions based on pre-defined severity status values, and (4) if the severity status for any vehicle condition exceeds a pre-defined severity threshold value, automatically transmit a text message to the cellular telephone. Another aspect includes a system for detecting and monitoring a vehicle's health status. The system comprises (1) a vehicle monitoring computer system and (2) a vehicle computer system configured to communicate wirelessly with a cellular telephone located within a vehicle or its vicinity to transmit diagnostic information to a telecommunications network for communication with the vehicle monitoring system.
