Vehicle Notification System Dynamic Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle notification systems transmit notification information based on pre-set importance, which may not align with the vehicle's current surroundings, potentially leading to inappropriate information being communicated to the driver.
Innovation Solution
A vehicle notification system comprising a surrounding information acquiring unit, a priority setting unit, and a notification unit that dynamically sets priority based on real-time surrounding information, ensuring that high-priority notifications are communicated to the driver accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notification information is transmitted based on pre-set importance, then the notification system is simple to operate, but the notification may not be appropriate for the vehicle's current surroundings
Solution Approach 1:
The notification system dynamically adjusts the priority of notification information based on real-time surrounding environment data. The priority setting unit changes the importance ranking of notifications according to detected surroundings, transforming a static pre-set system into a dynamic adaptive system that responds to current conditions, thereby improving notification appropriateness without requiring complete system redesign
Solution Approach 2:
The system incorporates feedback loops where surrounding information is continuously acquired, processed, and used to adjust notification priorities. The priority setting unit receives feedback from the surrounding information acquiring unit about current environmental conditions and modifies notification importance accordingly, creating a closed-loop control system that improves reliability through continuous adaptation
2Loss of information
If multiple items of notification information are transmitted simultaneously, then information completeness is improved, but information overload occurs making it difficult for the driver to focus on important notifications
Solution Approach 1:
The notification system transmits only the necessary subset of notification information at any given time rather than all available notifications simultaneously. The priority setting unit filters and selects notifications based on current surrounding conditions, transmitting partial information that is most relevant to the current situation, thereby preventing information overload while maintaining essential information completeness
Solution Approach 2:
Different notification information is assigned different priority levels based on local conditions and specific situations. The system applies different importance weights to different types of notifications depending on the surrounding environment, ensuring that critical safety-related notifications receive higher priority while less urgent notifications are deprioritized or delayed, making it easier for drivers to focus on important information
