Vehicle Steering Control for Multi-Obstacle Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face challenges in determining an appropriate steering assistance amount when multiple obstacles are present, as the steering assistance amount may be excessive or insufficient depending on the distance between obstacles, leading to inadequate collision avoidance.
Innovation Solution
A vehicle control apparatus that determines a steering assistance amount based on the distance between multiple obstacles in the direction of travel, using a determinator to calculate the assistance amount by considering the presence of obstacles on the same and opposite sides, thereby adjusting the steering assistance to ensure safe passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If steering assistance control is continuously performed for multiple obstacles, then collision avoidance is ensured, but the steering assistance amount becomes excessive or insufficient
Solution Approach 1:
The steering assistance amount is dynamically adjusted based on the distance between multiple obstacles. When multiple obstacles are detected, the system calculates the distance between them and modifies the steering assistance amount accordingly, making it larger when obstacles are close together and smaller when they are far apart, rather than applying a fixed assistance amount
Solution Approach 2:
The system changes the steering assistance amount parameter based on the spatial relationship between obstacles. By detecting the distance between multiple obstacles and adjusting the assistance amount as a variable parameter, the system optimizes steering control for different obstacle configurations
2Device complexity
If a fixed steering assistance amount is used for each obstacle, then simple control is maintained, but the steering assistance is not appropriate when obstacles are at different distances
Solution Approach 1:
The steering assistance amount transitions from a fixed value to a dynamic value that automatically adjusts based on obstacle distance. The system maintains simple control architecture while achieving precise steering assistance by making the assistance amount adaptive to the actual obstacle configuration
