Intersection Route Setting Based on Vehicle Attributes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route setting technologies for autonomously moving objects, such as vehicles, are unable to effectively set routes within intersections, as the optimal route depends on the attributes of the moving object, such as size and type.
Innovation Solution
A route setting apparatus that utilizes attribute information of the moving object, entry-exit information, and target position information to set a determination rule for setting routes within intersections, allowing for the selection of an appropriate route based on the moving object's attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a general car navigation apparatus is used to set routes, then the route setting process is simple, but it cannot set routes within intersections
Solution Approach 1:
The patent introduces an intersection management system as an intermediary between the navigation apparatus and the road network. This system specifically handles intersection route setting by calculating optimal trajectories through intersections based on entry and exit lanes, acting as a specialized mediator that bridges the gap between general navigation and complex intersection navigation
Solution Approach 2:
The patent segments the route setting function into two parts: general route setting handled by conventional navigation apparatus, and intersection-specific route setting handled by a dedicated intersection management system. This segmentation allows each component to specialize in its domain without requiring the entire system to be overly complex
2Adaptability or versatility
If a single route is set for all moving objects, then the route setting process is simple, but it cannot accommodate different attributes of moving objects
Solution Approach 1:
The patent applies local quality by setting different route parameters specifically for different types of moving objects (e.g., wide vehicles, long vehicles) based on their attributes. The system determines appropriate routes tailored to each object's characteristics rather than applying a universal route, allowing customized route optimization for specific vehicle types while maintaining a unified system architecture
Solution Approach 2:
The patent implements dynamic route setting where the route parameters are adjusted based on the attributes of the moving object. The system dynamically determines route information such as target positions and trajectories according to whether the vehicle is wide, long, or has other specific characteristics, making the route setting flexible and adaptive rather than static
3Reliability
If conventional route setting methods are used, then the system is easy to operate, but it cannot provide stable and efficient routes for moving objects through intersections
Solution Approach 1:
The patent implements self-service by enabling the intersection management system to automatically calculate and determine optimal routes for moving objects through intersections. The system autonomously processes entry lane, exit lane, and vehicle attribute information to generate appropriate route trajectories without requiring manual intervention, thereby ensuring reliable and efficient routing while maintaining operational simplicity

AI summary
An acquisition unit (110) acquires attribute information of a moving object, entry-exit information, and target position information. The entry-exit information is for specifying an entry position to an intersection and an exit position from the intersection. The attribute information of the moving object is information regarding the moving object. The target position information is information indicating a target position located in the intersection. The target position indicates a position at least near which a route of the moving object is to pass. A determination rule setting unit (120) sets a rule used when the route is determined, by using the attribute information of the moving object. A route setting unit (130) sets the above-described route using the rule set by the determination rule setting unit (120), and the entry-exit information and the target position information acquired by the acquisition unit (110) .
