Autonomous Parking Navigation Using Digital Car Park Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems lack digital maps of parking spaces, making autonomous vehicle navigation within parking lots difficult or impossible.
Innovation Solution
A method and device that transmit a digital map of a parking space and target position to a vehicle via a communication network, enabling the vehicle to autonomously navigate and park within the space, using a guidance device for independent longitudinal and transverse guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional navigation systems are used without digital maps of parking spaces, then the system structure remains simple, but autonomous navigation within parking lots becomes difficult or impossible
Solution Approach 1:
The system receives and stores digital map data of the parking space in advance before the vehicle needs to navigate. The server prepares the complete parking space map including boundaries, obstacles, and target positions beforehand, so that when the vehicle arrives, navigation can immediately begin using pre-prepared spatial information.
Solution Approach 2:
A server acts as an intermediary between the navigation system and the vehicle. The server receives digital maps, processes them, determines target positions, and transmits this information to the vehicle's navigation system. This intermediary handles the complexity of map management and route calculation, allowing the vehicle to focus on execution.
2Reliability
If a server with database and processing capabilities is introduced to provide digital maps and target positions, then autonomous navigation is enabled, but system complexity increases
Solution Approach 1:
The server performs multiple functions: storing digital maps in the database, determining target positions based on vehicle and obstacle information, calculating routes, and transmitting navigation data. This multi-functional approach consolidates what could be separate complex systems into a single coordinated platform.
Solution Approach 2:
The system replaces manual driver navigation decisions with automated server-based processing. The server's processor automatically determines target positions and calculates routes by processing digital map data, obstacle information, and vehicle coordinates, substituting human cognitive processes with automated computational processes.
3Adaptability or versatility
If the vehicle determines its own route internally, then independence from external systems is improved, but navigation efficiency may be reduced compared to server-determined routes
Solution Approach 1:
The system allows dynamic selection between server-determined routes and vehicle-determined routes. The server can provide pre-calculated efficient routes when available, while the vehicle retains the capability to independently determine routes when needed, creating a flexible system that adapts to different operational requirements.
