Adaptive Vehicle Acceleration Limits Based on Driver Behavior Score
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing acceleration limiting methods do not adapt to individual driver behavior, leading to insufficient or excessive acceleration limits for beginners and experienced drivers, respectively, and fail to provide a smooth driving experience.
Innovation Solution
A method to determine a driver's driving score based on vehicle information, adjusting the acceleration limit level dynamically to match the driver's behavior, using sensors for vehicle speed, distance, pedal operation, and torque, and providing feedback on score changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed acceleration limit value is applied, then the device complexity is reduced and ease of operation is improved, but the adaptability to different driver behaviors deteriorates
Solution Approach 1:
The acceleration limit is changed from a fixed value to a dynamic value that automatically adjusts based on the driver's behavior score. The control unit modifies the acceleration limit in real-time according to the driver's performance, making the system adaptive without requiring manual intervention from the driver.
Solution Approach 2:
The system changes the acceleration limit parameter based on the driver's behavior score. When the score improves, the acceleration limit is increased; when the score deteriorates, the acceleration limit is decreased. This dynamic parameter adjustment resolves the contradiction between ease of operation and adaptability.
2Reliability
If a restrictive acceleration limit is applied to beginner drivers, then safety is improved, but the driving experience and satisfaction deteriorate
Solution Approach 1:
The acceleration limit dynamically adjusts based on the driver's behavior score, which reflects their skill level. Beginner drivers with lower scores receive more restrictive limits for safety, while experienced drivers with higher scores receive higher limits that provide better driving experience and satisfaction.
Solution Approach 2:
The system provides feedback to the driver through the behavior score, which is displayed to show improvement progress. This feedback mechanism motivates drivers to improve their skills while the acceleration limit adjusts accordingly, balancing safety requirements with driving experience.
3Ease of operation
If the acceleration limit is increased for experienced drivers, then driving satisfaction is improved, but safety risks increase
Solution Approach 1:
The system continuously monitors driver behavior and updates the behavior score in real-time. Even for experienced drivers with high scores and higher acceleration limits, the system maintains safety by providing continuous feedback and being ready to adjust the limit if the driver's performance deteriorates.
Solution Approach 2:
The acceleration limit remains dynamic even for experienced drivers, adjusting up or down based on current performance. This ensures that driving satisfaction is improved through higher limits while safety is maintained through continuous monitoring and adjustment capability.
