Adaptive Drive Assist Control for Driver Skill Categories
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle drive assist technologies fail to provide appropriate control based on the difference in drive characteristics among drivers, despite considering road friction coefficients and drive skills.
Innovation Solution
A vehicle drive assist apparatus that acquires road condition and drive skill information, determines relevant categories, and executes a drive assist process tailored to the specific road conditions and drive skills of the driver, adjusting driving force limitations based on the driver's skill level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drive assist control is applied uniformly to all drivers, then implementation simplicity is maintained, but drive assist appropriateness deteriorates due to ignoring individual drive characteristics
Solution Approach 1:
The patent segments drivers into different categories based on their drive characteristics (e.g., aggressive drivers, conservative drivers, novice drivers). This segmentation allows the control system to apply different drive assist control strategies tailored to each driver category, improving drive assist appropriateness without requiring complex individualized analysis for every driver. The segmentation is achieved by analyzing driving behavior data and clustering drivers into distinct groups with similar characteristics.
Solution Approach 2:
The patent changes the parameter of drive assist control strength based on the determined driver category. For example, aggressive drivers may receive stronger deceleration assistance or earlier warnings, while conservative drivers may receive gentler assistance. This parameter adjustment allows the system to adapt control intensity to match individual drive characteristics, enhancing appropriateness while maintaining a manageable control architecture.
2Reliability
If drive assist control is intensified to improve safety, then safety performance is improved, but driver comfort deteriorates due to excessive intervention
Solution Approach 1:
The patent applies different levels of drive assist control intensity to different driver categories based on their individual characteristics. For example, novice drivers or drivers with poor safety records may receive more intensive control assistance, while experienced and safety-conscious drivers receive minimal intervention. This localized quality adjustment ensures that safety-critical drivers get enhanced protection without subjecting all drivers to unnecessary intervention, thereby maintaining driver comfort.
Solution Approach 2:
The drive assist control intensity is dynamically adjusted based on the determined driver category and real-time driving conditions. The system can adapt the level of assistance provided, increasing control strength when safety risks are detected for specific driver categories and reducing it when conditions are safe. This dynamic adjustment optimizes both safety performance and driver comfort by matching control intensity to actual needs.
