Vehicle Control Device Timing Notifications for Low Driving Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems often annoy users by requesting the use of driving support devices during high driving load conditions, such as lane changes or heavy traffic, which can be distracting and inconvenient.
Innovation Solution
A vehicle control device that assesses driving load conditions and only requests the use of driving support systems when the load is low, avoiding sections with high merging, branching, road gradients, rain, lane regulations, or traffic congestion, and ensuring the user is not operating accessory devices, thus minimizing annoyance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system requests the user to use the driving support device during high driving load conditions, then the user may be reminded to use the safety feature, but the user is likely to feel annoyed and distracted
Solution Approach 1:
The system performs preliminary assessment of driving load conditions before issuing notifications. By evaluating path information, weather conditions, and traffic状况 in advance, the system determines whether the current conditions are suitable for requesting driving support device usage, thereby avoiding notifications during high-load periods that would cause user annoyance
Solution Approach 2:
The system continuously monitors driving load conditions and provides feedback on whether notification should be issued. By comparing real-time conditions against predefined thresholds for driving load, the system dynamically adjusts notification timing to ensure user acceptance while promoting driving support device usage
2Reliability
If the system frequently notifies the user to use the driving support device, then the reminder function is enhanced, but the user experience deteriorates due to repeated interruptions
Solution Approach 1:
The system implements periodic evaluation of driving conditions rather than continuous notification attempts. By setting appropriate time intervals and condition thresholds, the system notifies users only when conditions are favorable and sufficient time has passed since the last notification, balancing reminder effectiveness with user experience
3Measurement precision
If the system processes path information and weather data in real-time, then the accuracy of driving load assessment is improved, but the calculation load increases
Solution Approach 1:
The system performs preliminary processing of path information and weather data before they are needed for driving load assessment. By pre-processing and storing relevant information, the system reduces the calculation load during real-time operation while maintaining assessment accuracy
Solution Approach 2:
The system extracts only the essential features from path information and weather data that are relevant to driving load assessment. By filtering and selecting only the critical parameters, the system maintains measurement precision while reducing the overall calculation load
