Autonomous Vehicle Path Occupation Right Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous driving vehicles lack a reliable mechanism to prevent collisions by ensuring exclusive access to specific path sections, which is crucial for maintaining safety and preventing accidents.
Innovation Solution
An autonomous driving vehicle and management apparatus that utilize a wireless communication unit to request and manage exclusive occupation rights for path sections, using an electronic map to determine optimal routes and adjust speed and direction, while a controller ensures safe travel by approving or rejecting occupation right requests based on predefined rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous driving vehicles use sensors and GPS to detect and navigate independently, then the vehicle can travel autonomously without driver intervention, but the system lacks a reliable mechanism to guarantee exclusive path access and prevent collisions with other vehicles
Solution Approach 1:
The patent introduces a path management server as an intermediary between autonomous vehicles and the path sections they occupy. This server coordinates occupation right requests from multiple vehicles, granting exclusive access rights to specific path sections for predetermined time periods. This mediator resolves the collision prevention reliability issue by centrally managing path access without requiring complex inter-vehicle communication or sensing between autonomous vehicles themselves.
2Reliability
If the system grants exclusive occupation rights to vehicles for path sections, then collision prevention is improved, but the system complexity increases due to the need for coordination and approval mechanisms
Solution Approach 1:
The patent divides the driving path into discrete path sections, each of which can be independently occupied by a vehicle for a predetermined time period. This segmentation allows the path management server to handle smaller, more manageable allocation units rather than managing entire routes or large geographic areas at once. The electronic map stores identification information for each section, enabling granular control and reducing the overall complexity of path coordination.
3Reliability
If the autonomous driving vehicle requests and receives approval for occupation rights before traveling, then path access safety is improved, but the travel time increases due to the approval process
Solution Approach 1:
The patent implements preliminary action by requiring autonomous vehicles to request occupation rights for path sections before actually traveling through them. The path management server processes these requests in advance and grants approval, ensuring that when a vehicle enters a path section, it has already secured exclusive access rights. This preliminary coordination prevents last-minute conflicts and reduces the need for emergency braking or route changes during travel.

AI summary
An autonomous driving vehicle, an autonomous driving management apparatus, and a method of controlling the same. The autonomous driving vehicle includes: a wireless communication unit configured to receive position information about the vehicle; a storage unit configured to store an electronic map; an input unit configured to receive a destination; a driving unit configured to adjust a travelling speed and a travelling direction; and a controller configured to search for a path from a point corresponding to the position information to a point corresponding to the destination in the electronic map, and control the vehicle to travel the approved section through the driving unit when receiving an approval of an occupation right for one or more sections included in the path through the wireless communication unit.
