Vehicle Notification Controller Threshold Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems often provide unnecessary and confusing notifications when switching from engine traveling mode to EV traveling mode is disabled, as they notify the user every time the switching control is disabled, even if the disabled state is apparent, leading to user frustration and increased information overload.
Innovation Solution
A vehicle control apparatus with a condition determining unit, mode switching controller, and notification controller that determines whether enabling conditions for switching to an engine stop mode are satisfied, and only notifies the user when a measured time value exceeds a threshold, thereby reducing frequent notifications and providing appropriate timing for notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system notifies the user every time switching control is disabled, then the user is informed of the disabled state, but the user experiences information overload and frustration
Solution Approach 1:
The notification controller implements periodic action by comparing the measured time value with a threshold value to determine when notifications should be made. Notifications are not issued continuously or at every disabling event, but only at periodic intervals when the threshold is exceeded, thereby reducing information overload while maintaining essential user awareness
Solution Approach 2:
The system changes the parameter of notification frequency by introducing a time-based threshold mechanism. Instead of notifying at every switching disablement, the system adjusts the notification parameter to only trigger when the disabled state persists beyond a predetermined time threshold, thus filtering out transient or unnecessary notifications
2Loss of information
If the system provides detailed information about disabled switching, then the user can identify causes, but the user receives overwhelming information
Solution Approach 1:
The notification controller extracts only the essential information needed for user awareness - specifically, it notifies only when the disabled state persists beyond the threshold time. This extraction principle filters out unnecessary notification events while retaining the critical information about sustained disabled states, reducing information volume while maintaining cause identification capability
3Speed
If the system notifies immediately when switching is disabled, then the user is promptly informed, but frequent notifications occur even for brief disabled states
Solution Approach 1:
The system performs preliminary action by measuring the time value of the disabled state before issuing a notification. Instead of notifying immediately upon disablement, the system first measures whether the disabled state persists beyond the threshold, thereby preventing premature or unnecessary notifications while still providing timely alerts for sustained issues

AI summary
A vehicle control apparatus includes a condition determining unit, a mode switching controller, and a notification controller. The condition determining unit is configured to determine whether enabling conditions set to enable a switching control to an engine stop mode are satisfied. The engine stop mode stops an engine of a vehicle in a driving state. The mode switching controller is configured to perform the switching control to the engine stop mode in response to that the condition determining unit determines that the enabling conditions are satisfied. The notification controller is configured to compare a measured time value and a threshold both related to the enabling condition which the condition determining unit determines as not being satisfied. The notification controller is configured to perform, in response to that the measured time value exceeds the threshold, a control of making notification that the switching control is in a disabled state.
