Vehicle Evacuation Guidance Using Other-Vehicle Driving Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle guidance systems fail to prevent overlap between a vehicle's driving line and another vehicle's driving line during evacuation, leading to potential interference.
Innovation Solution
A vehicle guidance system that uses a guide device to direct a vehicle away from an estimated driving line of another vehicle by utilizing information about the vehicle's driving course, estimated driving line, and current position, prompting the user to move in an evacuation direction that avoids overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle guidance system guides the vehicle to a pre-set evacuation destination, then the vehicle can be evacuated to a safe area, but the driving line of the vehicle may overlap with the driving line of other vehicles causing interference
Solution Approach 1:
The system pre-calculates and stores multiple evacuation destinations and their corresponding driving lines before an emergency occurs. When evacuation is needed, the system quickly selects from pre-prepared routes, avoiding the need to calculate routes in real-time during the emergency situation.
Solution Approach 2:
The system obtains information about other vehicles' driving lines and uses this feedback to adjust the selected evacuation route. The guide device compares the pre-calculated evacuation driving line with actual other vehicle driving line information and modifies the guidance to avoid overlap and interference.
2Object-affected harmful factors
If the vehicle follows the guided evacuation direction, then overlap with other vehicles is suppressed, but the guidance system requires real-time information about other vehicles' driving lines
Solution Approach 1:
The system pre-calculates multiple evacuation routes and stores them in advance. This preliminary preparation ensures that route information is already available without needing to gather real-time data about other vehicles during the evacuation process.
Solution Approach 2:
The system uses a server or communication system as an intermediary to obtain other vehicle's driving line information. This intermediary collects and processes information from multiple sources, making it easier for the guidance system to access necessary data without direct real-time communication with each other vehicle.

AI summary
A vehicle guidance system of the present disclosure includes a guide device that guides the vehicle in a direction away from an estimated driving line estimated to be driven by other vehicle different from the vehicle as the evacuation direction based on the first information about a driving course on which the vehicle drive, the second information about the estimated driving line, and the third information about a current position of the vehicle.
