Vehicle Path Planning via Positional Segmentation and Intermediary Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle driving methods are inefficient in planning travel paths, particularly in congested road conditions where ambulances need to quickly pass through, leading to delays in emergency situations.
Innovation Solution
A control method for vehicle driving that acquires real-time position information of vehicles within a preset distance range, determines their positional relationships, and adjusts their travel paths through communication instructions to improve driving efficiency and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicles follow traditional driving methods without real-time communication, then driving operations are simple, but driving efficiency is low and emergency passage is delayed
Solution Approach 1:
The system performs preliminary actions by acquiring position information of surrounding vehicles in advance and pre-calculating alternative travel paths before emergency situations occur. When an ambulance needs to pass, the path planning is already prepared, enabling immediate execution without delay.
Solution Approach 2:
The patent introduces a communication system as an intermediary between vehicles. The terminal device sends communication instructions to vehicles in the first position, mediating the coordination between the ambulance and other vehicles to resolve congestion and enable efficient emergency passage.
2Loss of time
If real-time position information is acquired and communication instructions are sent to adjust travel paths, then driving efficiency is improved, but information processing complexity increases
Solution Approach 1:
The system continuously acquires position information of vehicles in preset distance ranges in advance and pre-establishes communication protocols. When emergency passage is needed, the pre-prepared information and protocols enable rapid response without time loss.
Solution Approach 2:
The system segments the road environment into multiple position ranges (first position, second position, third position) based on distance and spatial relationship. This segmentation allows targeted information processing for different vehicle groups, reducing overall processing complexity while improving efficiency.
3Measurement precision
If vehicles in different positions are identified and targeted communication is implemented, then path planning accuracy is improved, but detection and measurement difficulty increases
Solution Approach 1:
The system divides the spatial environment into segmented position ranges (first position for vehicles directly ahead, second position for left-side vehicles, third position for right-side vehicles) based on directional relationships. This segmentation simplifies the detection process by focusing on specific spatial zones rather than analyzing all possible positions simultaneously.
Solution Approach 2:
The patent applies local quality by treating different position ranges with different communication strategies. Vehicles in the first position receive specific instructions compared to those in second or third positions, optimizing the precision of positional relationships for each local context.
