Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated driving systems lack the ability to dynamically manage imaginary lines and stop lines, especially in the presence of obstacles, which can hinder efficient and safe vehicle navigation.
Innovation Solution
An automated driving vehicle management system that includes an imaginary line management unit and an imaginary stop line management unit, capable of generating, updating, and adjusting these lines to avoid obstacles and manage traffic flow, using a communication unit to share this information with vehicles for coordinated navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If automated driving systems use fixed road markings and static map information for navigation, then the system structure is simple, but the system cannot adapt to dynamic obstacles and changing road conditions
Solution Approach 1:
The patent applies the Dynamics principle by transforming static road markings into dynamic virtual lines that can be generated, moved, and deleted in real-time. The management server dynamically creates virtual road markings (first through fourth virtual lines) based on detected obstacles and communicates them to automated driving vehicles, enabling the system to adapt to changing conditions without physical infrastructure modifications.
Solution Approach 2:
The patent uses an intermediary approach by introducing a management server that acts as a mediator between obstacle detection and vehicle navigation. The server generates virtual road markings as an intermediate representation of road conditions, translating complex obstacle information into simplified navigational guidance that vehicles can easily follow.
2Reliability
If the system generates virtual stop lines and imaginary lines to manage traffic flow, then traffic safety improves, but the complexity of line management increases
Solution Approach 1:
The patent applies segmentation by dividing the virtual road marking system into distinct functional components: first and second virtual lines for lane guidance, third virtual lines for stop indications, and fourth virtual lines for obstacle avoidance. Each segment serves a specific safety function, making the overall complex system manageable through modular organization.
Solution Approach 2:
The system implements preliminary action by pre-defining the structural framework for virtual road markings with specific geometric relationships. The management server calculates and establishes the relative positions, angles, and distances between different virtual line segments in advance, enabling rapid deployment and adjustment without complex real-time computations.
3Reliability
If the imaginary line position is fixed based on map information, then the system is easy to implement, but it cannot avoid obstacles effectively
Solution Approach 1:
The patent implements feedback by continuously monitoring obstacle positions and using this information to adjust the positions of virtual road markings. The management server receives obstacle detection data, recalculates the appropriate positions for first through fourth virtual lines, and communicates updated markings to vehicles, creating a closed-loop system that adapts to real-time conditions.
