Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with installed application software, existing technologies do not effectively enhance driving safety by appropriately addressing abnormalities in the software that could impact safe driving.
Innovation Solution
A vehicle monitoring program and device that includes a monitoring unit to detect abnormalities in application software and an abnormality processing unit to select an appropriate response based on the adverse effect level on safe driving, allowing for tailored measures such as notification to the driver or external systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single fixed abnormality process is used for all application software abnormalities, then the system is simple to implement, but it cannot effectively address varying impacts on driving safety
Solution Approach 1:
The patent segments the abnormality processing into multiple levels based on adverse effect levels. Different abnormality processes are defined for different severity levels, allowing the system to respond appropriately to each type of abnormality without using a single fixed process for all cases.
Solution Approach 2:
The patent introduces dynamic selection of abnormality processes based on the detected adverse effect level. The system dynamically determines which abnormality process to execute by evaluating the severity of the abnormality, making the system adaptable rather than static.
2Reliability
If multiple abnormality processes are implemented with different adverse effect levels, then driving safety is effectively enhanced, but the system complexity increases
Solution Approach 1:
The monitoring unit automatically detects abnormalities and determines adverse effect levels without requiring manual intervention. The system self-manages the complexity by autonomously selecting and executing the appropriate abnormality process based on detected conditions.
Solution Approach 2:
The system implements feedback mechanisms where the monitoring unit continuously monitors application software and provides information about detected abnormalities. This feedback loop enables automatic determination of adverse effect levels and selection of appropriate responses.
3Reliability
If comprehensive monitoring of application software is performed, then driving safety is improved, but the monitoring complexity and resource consumption increase
Solution Approach 1:
The patent applies partial monitoring by focusing on specific abnormality conditions and adverse effect levels rather than monitoring all possible software behaviors. The system performs monitoring at the necessary level of detail without excessive resource consumption.
