Road Surface Degradation Evaluation for Vehicle Steering Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic steering technologies for vehicles do not account for the degradation status of road surfaces, which can significantly impact travel difficulty, leading to inadequate travel assistance.
Innovation Solution
An information processing apparatus that acquires road surface degradation status information and calculates an evaluation value indicative of travel difficulty, providing assistance by adjusting the steering wheel position and driver feedback based on this evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic steering technology is implemented without considering road surface degradation, then automation level is improved, but travel safety and reliability deteriorate due to inadequate travel assistance
Solution Approach 1:
The system acquires road surface degradation status information and calculates evaluation values to provide feedback to the driver about travel difficulty. This feedback mechanism allows the automatic steering system to inform drivers about road conditions, enabling them to make informed decisions about when to switch to manual control, thereby improving reliability while maintaining automation.
Solution Approach 2:
The system performs preliminary assessment of road surface degradation status before the driver encounters difficult traveling conditions. By calculating evaluation values based on acquired degradation information in advance, the system prepares travel assistance data that can be immediately provided to the driver, enhancing safety without compromising automation level.
2Reliability
If road surface degradation status is acquired and evaluated, then travel safety and reliability are improved, but device complexity increases
Solution Approach 1:
The system introduces an information processing apparatus as an intermediary that acquires road surface degradation status information and calculates evaluation values. This intermediary component processes complex degradation data and transforms it into simplified evaluation information that can be easily understood by the driver, thereby improving reliability without directly increasing the complexity visible to the user.
3Ease of operation
If real-time road surface evaluation is provided, then travel assistance quality is improved, but information processing time and computational load increase
Solution Approach 1:
The system calculates evaluation values based on acquired road surface degradation status information, focusing on providing sufficient travel assistance information rather than processing every possible parameter. This partial action approach delivers the necessary travel assistance quality while avoiding excessive computational processing time.
