Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driver assistance systems do not adequately account for individual driver preferences and road features when providing feedback to maintain a comfortable distance from road boundaries, leading to discomfort in various driving scenarios.
Innovation Solution
A driver assistance system that uses sensors and a controller to determine the location of road boundaries, select parameters based on driver preferences and road features, and provide feedback operations, such as assist forces and warnings, to help the driver maintain a desired distance from the boundary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed feedback operation is provided to assist the driver in avoiding the road boundary, then the system structure is simple, but the driver comfort is poor because it does not account for individual driver preferences and road features
Solution Approach 1:
The feedback operation is made dynamic by adjusting its magnitude based on real-time detection of road boundary distance and selection of parameters reflecting driver preferences and road features. The controller continuously adapts the feedback magnitude rather than using a fixed value, resolving the contradiction between simple system structure and driver comfort.
Solution Approach 2:
The system changes the parameter of feedback magnitude based on detected road boundary distance and selected parameters. By varying the feedback magnitude according to multiple factors (distance, driver preference, road features), the system achieves high driver comfort without requiring overly complex structural changes.
2Ease of operation
If the system provides feedback based on multiple parameters including driver preferences and road features, then driver comfort is improved, but the device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The controller is designed to perform multiple functions: detecting road boundary distance, selecting parameters based on driver preferences, identifying road features, and determining feedback magnitude. By making the controller multi-functional rather than adding separate dedicated systems for each function, the system achieves high driver comfort with minimized additional complexity.
Solution Approach 2:
The system uses existing vehicle sensors and the controller's processing capabilities to gather necessary information about road boundaries and vehicle position. Rather than requiring entirely new sensing systems, the invention leverages available resources to reduce the complexity increase while maintaining high driver comfort.
3Measurement precision
If the feedback magnitude is adjusted based on detected distance and selected parameters, then the accuracy of driver assistance is improved, but the processing time increases due to real-time analysis requirements
Solution Approach 1:
Parameters related to driver preferences and road features are selected and stored in advance based on pre-stored information about road segments. This preliminary selection reduces the real-time processing burden, allowing the system to maintain high feedback accuracy while minimizing additional processing time delays.
Solution Approach 2:
The system continuously monitors the actual distance to the road boundary and compares it with the target distance derived from selected parameters. This closed-loop feedback mechanism ensures high accuracy in feedback magnitude determination while using efficient comparison algorithms that minimize processing time.

AI summary
A method of assisting a driver of a vehicle in driving a road, the method includes determining a location of a road boundary relative to the vehicle using a sensor, selecting, via a controller, a parameter to assist a driver of the vehicle at the location of the road boundary, updating the parameter based on a previous operation of the vehicle, determining, via the controller, whether the vehicle is approaching the road boundary based on a vehicle trajectory and the location of a road boundary, and providing a feedback operation to assist the driver in avoiding the road boundary, the feedback operation based on the selected parameter.
