Automatic Parking Path Switching for Obstacle-Aware Maneuvering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic vehicle parking systems face challenges in complex and changing environments, leading to safety risks and poor user experience due to obstacles like wheel chocks, bumps, and slopes, requiring manual intervention.
Innovation Solution
The system switches to a new parking path when specific events occur, such as getting stuck, collision, or stopping prematurely, using chassis tracking information to adapt the parking route and avoid obstacles, ensuring the vehicle completes parking safely and efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the vehicle directly travels across the obstacle during automatic parking, then the parking process continues without manual intervention, but the vehicle may fail to cross or collide causing safety risks
Solution Approach 1:
The system continuously monitors parking status through chassis tracking information and event detection. When an obstacle is detected during parking, the system receives feedback about the abnormal condition and automatically adjusts the parking path or completes parking, eliminating the need for manual intervention while ensuring safety.
Solution Approach 2:
The parking path is made dynamic and adaptable. Instead of following a fixed predetermined path, the system can switch between different parking paths (first parking path, second parking path) based on real-time obstacle detection, allowing the vehicle to adapt its motion trajectory to avoid collisions while maintaining automatic operation.
2Reliability
If the vehicle does not travel across the obstacle during automatic parking, then safety is maintained, but the vehicle may not be parked in place requiring manual takeover
Solution Approach 1:
The system performs self-service by automatically detecting parking completion status and determining whether manual intervention is needed. Through chassis tracking information and event detection, the system autonomously judges whether the vehicle has successfully parked or needs to switch paths, reducing manual takeover requirements while ensuring safe parking completion.
3Reliability
If the vehicle switches to a new parking path when events occur, then safety and parking success rate improve, but system complexity increases
Solution Approach 1:
The parking control system is segmented into distinct functional modules: event detection module, path planning module, and execution module. The path itself is segmented into alternative routes (first parking path, second parking path). This modular segmentation manages complexity by dividing the control logic into manageable, independent components that can be developed and tested separately.

AI summary
Example intelligent parking methods and apparatuses are provided. In one example method, a vehicle is parked based on a first parking path. In response to determining that a first event occurs, the vehicle can complete parking, or can park based on a second parking path, where the second parking path is different from the first parking path. In an automatic parking process, when the first event occurs, the vehicle may switch a parking solution, to effectively avoid a safety risk or slow-start parking experience caused by continuing to park based on an original parking route.
