Travel Route Hazard Mapping for Safer Automated Vehicle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated travel systems do not adequately address the risk of accidents at dangerous locations on travel routes, lacking consideration for safe vehicle operation.
Innovation Solution
A travel route generation device that acquires position and environment information, detects dangerous locations, and adds relevant information to the travel route data, allowing for speed reduction or specific operations to mitigate risks, integrated with a control device for autonomous or remotely controlled vehicle travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated travel is implemented without considering dangerous locations, then travel efficiency and automation extent are improved, but safety and reliability deteriorate
Solution Approach 1:
The system performs preliminary detection of dangerous locations along the travel route before automated travel begins. The dangerous location detection unit identifies hazardous areas in advance, and this information is stored and used to guide automated travel decisions, ensuring safety considerations are built into the automation from the outset
Solution Approach 2:
The system continuously monitors the vehicle's position relative to detected dangerous locations and provides feedback to the travel control device. When the vehicle approaches a dangerous location, the system adjusts travel parameters (such as reducing speed or changing route) to maintain safety while preserving automated operation
2Reliability
If dangerous location detection and response measures are added to automated travel systems, then travel safety is improved, but device complexity and processing requirements increase
Solution Approach 1:
The dangerous location detection unit utilizes the existing surrounding environment information acquisition capabilities of the automated travel system. By making the detection unit share the same sensing infrastructure and data processing pipelines already present in the automated vehicle, the system adds safety functionality without proportionally increasing overall device complexity
Solution Approach 2:
The system combines dangerous location detection with the existing travel route management and control functions. The dangerous location information is integrated into the same data structures and control loops that manage automated travel, allowing multiple functions to be implemented through shared computational resources and unified system architecture
