Vehicle Failure Notification Filtering by Option Function Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles equipped with option functions, drivers are unnecessarily notified of failures in instruments not relevant to their usage, leading to inconvenience in the development of sustainable transportation systems.
Innovation Solution
A failure management system and method that includes a device with an information collection unit, a notification unit, and an instruction unit to selectively output failure notices based on whether the failed instrument is involved in permitted option functions, using management information to determine whether to notify the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If failure notification is issued for all in-vehicle instruments, then comprehensive failure monitoring is achieved, but driver disturbance increases due to irrelevant notifications
Solution Approach 1:
The failure notification system is segmented by function type. The notification determination unit divides instruments into standard function instruments and option function instruments, applying different notification rules to each segment. This segmentation allows comprehensive monitoring of all instruments while selectively notifying only about relevant failures, resolving the contradiction between monitoring coverage and driver convenience.
Solution Approach 2:
Different notification policies are applied to different parts of the system. Standard function instruments use one notification policy (notify all failures), while option function instruments use another policy (notify only active option failures). This local differentiation enables the system to maintain high reliability through comprehensive monitoring while improving ease of operation by filtering out irrelevant notifications for the driver.
2Adaptability or versatility
If option functions are loaded in vehicle beforehand, then functional versatility is improved, but notification complexity increases due to multiple utilization states
Solution Approach 1:
The system performs preliminary classification of instruments into standard and option function categories during system setup. The notification determination unit pre-establishes the utilization state tracking mechanism for option functions, determining which options are active before failures occur. This preliminary organization simplifies the notification management process by having clear classification rules ready, reducing the complexity that would otherwise arise from managing multiple utilization states.
Solution Approach 2:
The notification system dynamically adapts to the utilization state of option functions. The notification determination unit continuously monitors whether option functions are currently active or inactive, and adjusts notification behavior accordingly. This dynamic approach allows the system to maintain versatility by supporting multiple option configurations while managing notification complexity through real-time state-aware decision making.

AI summary
A failure management device includes: an information collection unit configured to collect failure information which is information about a failure of devices or instruments loaded in a vehicle; a notification unit configured to output a failure notice notifying occurrence of the failure inside the vehicle; and an instruction unit configured to instruct the notification unit whether or not to output the failure notice when the failure of one of the devices or the instruments is found based on the failure information, and the instruction unit prohibits the notification unit from outputting the failure notice when the device or the instrument in which the failure is found is not involved in execution of an option function for which the execution is permitted, based on management information indicating whether or not the execution of the option function is permitted for each of the option functions in the vehicle.
