Route Evaluation Device for Interference-Aware Path Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route evaluation systems do not adequately consider the operations of other vehicles, potentially forcing drivers to perform sudden avoidance or braking maneuvers, which can lead to unsafe traffic environments.
Innovation Solution
A route evaluation device that generates route candidates for a host-vehicle by predicting the routes of other mobile objects, classifying interference forms, and evaluating these candidates based on interference patterns to prioritize safe routes that avoid conflicts with other vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the host-vehicle travels along a route that minimizes collision probability with other vehicles, then the host-vehicle safety is improved, but the driver of another vehicle may be forced to perform sudden avoidance or braking operations
Solution Approach 1:
The patent changes the evaluation parameters from simple collision probability to interference form classification, considering the behavioral patterns and responsibility distribution in different interference scenarios. This allows the system to select routes that minimize not only collision risk but also the likelihood of forcing other drivers into sudden maneuvers.
Solution Approach 2:
The patent performs preliminary classification of interference forms and evaluation of route candidates before final route selection. By anticipating potential interference scenarios and evaluating them in advance, the system can choose routes that prevent harmful situations before they occur, rather than reacting to them.
2Reliability
If the route evaluation considers multiple interference forms and predicted routes of other vehicles, then the traffic environment safety is improved, but the computational complexity increases
Solution Approach 1:
The patent segments the route evaluation process into distinct functional units: route candidate generation, predicted route acquisition, interference form classification, and route evaluation. This modular segmentation allows each component to be optimized independently and simplifies the overall system architecture while handling multiple interference forms comprehensively.
Solution Approach 2:
The patent introduces an interference form classification unit as an intermediary between route candidate generation and final evaluation. This intermediary component organizes and categorizes potential interference scenarios, making the evaluation process more structured and manageable, thereby reducing system complexity while maintaining comprehensive safety assessment.
