Vehicle Trouble Sequence Display for Intermittent Fault Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques struggle to accurately determine whether a vehicle trouble is temporary, intermittent, or continuous, making it difficult for repair personnel to take appropriate actions.
Innovation Solution
An information processing apparatus and storage medium that acquire vehicle information including trouble codes, status, and date/time information from a server, generating display data to visualize the trouble sequence in a calendar format, allowing different modes for temporary, intermittent, or continuous troubles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only trouble codes are read from the control device, then the diagnosis process is simple, but it is impossible to accurately determine whether the trouble is temporary, intermittent, or continuous
Solution Approach 1:
The system performs preliminary actions by acquiring and storing date and time information along with trouble codes and status information in advance. This allows the system to have complete trouble sequence data ready before diagnosis is needed, enabling accurate determination of whether troubles are temporary, intermittent, or continuous without needing to perform complex real-time analysis.
Solution Approach 2:
The invention adds a temporal dimension to traditional trouble code diagnosis by incorporating date and time information. Instead of only analyzing the presence of trouble codes, the system now analyzes troubles across the time dimension, displaying them in chronological order to reveal patterns that indicate temporary, intermittent, or continuous trouble types.
2Measurement precision
If detailed vehicle information including date and time is acquired and analyzed, then accurate trouble identification is possible, but the processing complexity increases
Solution Approach 1:
The system creates a simplified representation or copy of the complex trouble sequence data by displaying it in an organized chronological format. Instead of processing raw data internally, the system generates a visual copy showing trouble codes, status, and timestamps in order, making complex information easily interpretable without requiring complex processing algorithms.
3Ease of operation
If trouble information is displayed in chronological order with date and time, then the trouble sequence becomes clear, but the data processing and storage requirements increase
Solution Approach 1:
The system extracts only the essential elements needed for trouble sequence analysis - specifically the date and time information, trouble codes, and status information - from the complete vehicle data set. By taking out only these critical components and organizing them chronologically, the system achieves clear trouble sequence visualization without needing to store and process all possible vehicle data.
Data Source
AI summary
An information processing is provided. An acquisition unit acquires, from a server that accumulates vehicle information, the vehicle information including a trouble code stored by a control device of a vehicle, a status about an event to be identified by the trouble code, and date and time information associated with the trouble code and the status. A generation unit generates display data for displaying a sequence of a trouble in the vehicle, based on the vehicle information that has been acquired by the acquisition unit. A display control unit causes a display device to display the display data that has been generated by the generation unit.
