Driver Assistance System with Concentration-Based Dynamic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems fail to provide suitable assistance based on the driver's concentration level, as the attributes and driving proficiency do not change significantly over a short period, leading to inadequate support during varying levels of driver attention.
Innovation Solution
A driver assistance system equipped with a concentration degree detection module, which adjusts the levels of driver assistance functions automatically based on the detected concentration level, distinguishing between auxiliary and safety systems, and considering the driving environment and skill level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the driver assistance system uses fixed assistance levels based on driver attributes and driving proficiency, then the system structure remains simple, but the system cannot adapt to varying driver concentration levels during driving
Solution Approach 1:
The patent implements dynamic adjustment of assistance levels based on real-time detection of driver concentration parameters. The system transitions from static assistance levels (based on fixed driver attributes) to dynamic levels that automatically adapt as driver concentration changes during operation, resolving the contradiction between adaptability and complexity by making the system responsive to operational conditions
Solution Approach 2:
The system incorporates feedback mechanisms by detecting driver concentration parameters (such as eye movement, head position, or operational responses) and using this feedback to automatically adjust assistance levels. This closed-loop approach enables the system to adapt to varying driver states without requiring complex manual reconfiguration
2Adaptability or versatility
If the system provides high assistance levels for all driver assistance functions when driver concentration is low, then driver safety is improved, but the system cannot provide differentiated assistance for different types of functions
Solution Approach 1:
The patent segments driver assistance functions into different categories (e.g., collision avoidance, lane keeping, adaptive cruise control) and applies different assistance level adjustment strategies to each segment. This allows the system to prioritize safety-critical functions while providing differentiated support for other functions based on driver concentration levels
Solution Approach 2:
The system applies local quality by providing different degrees of assistance enhancement to different function types based on their safety criticality. Safety-critical functions receive higher priority adjustment when driver concentration drops, while non-critical functions receive proportionate but differentiated support, ensuring overall safety while maintaining functional versatility
3Ease of operation
If the system automatically changes assistance levels based on driver concentration, then suitable driver assistance is provided, but the driver's manual control over assistance settings is reduced
Solution Approach 1:
The system implements self-service by automatically detecting driver concentration and adjusting assistance levels without requiring manual driver input. The system serves itself by using its own detection capabilities to make real-time adjustments, reducing the operational burden on the driver while maintaining adaptability through automatic response to driver states

AI summary
A driver assistance control device includes a detection part detecting a degree of concentration of a driver; an acquisition part acquiring assistance levels set by the driver; a driver assistance control part performing a plurality of the functions; and a changing part automatically changing setting of the plurality of the functions in accordance with the degree. The changing part automatically changes the settings of first driver assistance functions including one of a plurality of the functions so that the assistance levels become higher than the levels set by the driver when the degree becomes lower than a first value, and automatically changes the settings of second driver assistance functions including at least another of a plurality of the functions so that the assistance levels become higher than the levels set by the driver when the degree becomes lower than a second value different from the first value.
