Vehicle Collision Avoidance via Tire Direction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-collision systems in intelligent vehicles cannot effectively determine the risk of collision by considering the movement of other vehicles, particularly when another vehicle cuts in front of the driver's vehicle while maintaining its lane.
Innovation Solution
A vehicle control system comprising a camera, a tire detecting unit, and a controller that photographs a front image, detects the tire of a nearby vehicle, measures its direction, estimates the nearby vehicle's path, and determines the risk of collision to provide warnings or control the driver's vehicle to avoid collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If current anti-collision systems only monitor the driver's vehicle movement, then the system complexity is reduced, but the collision risk detection accuracy deteriorates
Solution Approach 1:
The patent uses tire direction as an intermediary indicator to infer the movement intent of nearby vehicles. By detecting the orientation of tires on nearby vehicles, the system can estimate their future paths without directly tracking their complex motion, thus improving collision risk detection while avoiding the need for complex multi-vehicle tracking systems
Solution Approach 2:
The patent replaces direct mechanical tracking of nearby vehicle movement with an optical detection system that captures tire orientation images. This substitution allows the system to infer vehicle intent through image processing rather than complex mechanical sensing, resolving the contradiction between system simplicity and detection accuracy
2Measurement precision
If the system tracks movement of multiple vehicles, then the collision risk detection accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent extracts only the critical information needed for collision detection - specifically tire direction - from nearby vehicles. By focusing solely on this key parameter rather than tracking all movement aspects of multiple vehicles, the system achieves accurate collision risk assessment while maintaining relative simplicity in the detection system
Solution Approach 2:
The system performs preliminary detection of tire direction to predict future vehicle paths before actual collision risk materializes. This advance detection based on tire orientation allows the system to prepare collision avoidance measures early, improving detection accuracy without requiring complex real-time multi-vehicle tracking
