Automatic Parking Using Pre-Mapped Trajectories in Common Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic parking systems require vehicles to detect surrounding parking spaces and drive to their vicinity before parking, making the process less intelligent and inefficient.
Innovation Solution
The system uses a pre-stored environment map to determine the vehicle's location and parking trajectory within a common parking area, allowing for direct parking without the need for the driver to manually position the vehicle near the space, utilizing GPS, image capturing, and SLAM technology to construct and update environment maps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the vehicle uses traditional automatic parking detection to find surrounding parking spaces, then the parking operation can be performed, but the vehicle must first be driven to a vicinity of the common parking space manually, which reduces automation and efficiency
Solution Approach 1:
The system pre-stores environment maps of common parking areas and pre-calculates parking trajectories for multiple parking spaces within these areas. When the vehicle enters a common parking area, the system can directly guide the vehicle to the target parking space using the pre-prepared trajectory, eliminating the need for manual positioning to a vicinity first. This preliminary preparation of maps and trajectories enables direct automatic parking execution.
2Adaptability or versatility
If the vehicle parks into common parking spaces using traditional methods, then parking is achieved, but the process is not intelligent enough as it requires manual intervention to reach the vicinity
Solution Approach 1:
The system enables the vehicle to automatically perform the complete parking process including navigation to the parking space, positioning, and parking execution. The pre-stored environment maps and calculated trajectories allow the vehicle's control system to autonomously determine the optimal path and execute parking without requiring the driver to manually drive the vehicle to a vicinity first, making the entire process self-service and fully automatic.
3Productivity
If the system uses pre-stored environment maps and parking trajectories, then direct parking into common parking spaces is enabled, but more computational resources are needed for map storage and trajectory calculation
Solution Approach 1:
The system pre-calculates and stores parking trajectories for multiple parking spaces within common parking areas before the vehicle arrives. The environment maps of common parking areas are pre-acquired and stored. When the vehicle needs to park in a common parking area, the system can directly retrieve the pre-stored map and trajectory data, avoiding real-time calculation complexity and enabling fast execution of the parking maneuver.
4Measurement precision
If the vehicle detects available parking spaces in real-time, then accurate parking is achieved, but the process is slower compared to using pre-stored information
Solution Approach 1:
The system pre-acquires environment maps of common parking areas that contain information about parking spaces. When the vehicle arrives at a common parking area, it retrieves the pre-stored map data which already contains parking space locations and characteristics. The system then matches the vehicle's current state with the pre-stored trajectory data to determine the optimal parking space, combining the speed of pre-stored information with the accuracy of targeted detection for the specific parking space to be used.
