Automated Parking Path Control for Unavoidable Obstacle Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated parking systems face challenges when an unavoidable obstacle is encountered on the parking path, as the vehicle interrupts the parking process and the user, who has entered a house, is not immediately aware of the situation, making it difficult to recognize and address the obstacle.
Innovation Solution
A parking assistance method that includes storing information on a travel path, detecting obstacles, determining if an avoiding path can be generated, and notifying the user via a communication terminal if the path cannot be avoided, allowing the user to remove the obstacle and resume automated parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated parking control is implemented, then parking efficiency is improved, but the system cannot respond to unavoidable obstacles when the user is not present
Solution Approach 1:
The system continuously detects obstacles during automated parking and provides feedback to the user via communication terminal. When an unavoidable obstacle is detected and no avoiding path can be generated, the system notifies the user to remove the obstacle, enabling the parking process to resume. This feedback mechanism resolves the contradiction by maintaining automated efficiency while ensuring reliable obstacle response through user notification.
2Ease of operation
If the user enters the house during automated parking, then user convenience is improved, but the user cannot recognize obstacles on the parking path
Solution Approach 1:
The communication terminal acts as an intermediary between the automated parking system and the user. It transmits obstacle detection information from the vehicle to the user's terminal device, allowing the user to remain inside the house while still receiving real-time information about obstacles on the parking path. This resolves the contradiction by maintaining user convenience while preventing information loss through digital notification.
3Reliability
If the vehicle stops when an obstacle is detected, then safety is improved, but the parking process is interrupted and time is lost
Solution Approach 1:
The system applies partial stopping action by pausing the automated parking process only when unavoidable obstacles are detected, rather than stopping for all obstacles. When avoiding paths are available, the system continues parking automatically. This resolves the contradiction by maintaining safety through selective stopping while minimizing time loss by resuming automatically when safe to proceed.

AI summary
A parking assistance method according to the present disclosure is a method for performing automated traveling of a vehicle based on teacher traveling by a user. The method includes: causing a memory to store information on a travel path in teacher traveling; controlling the vehicle based on the stored travel path; detecting an obstacle during controlling the vehicle; determining whether an avoiding path for avoiding the obstacle is able to be generated; and notifying, when the avoiding path is not able to be generated, a communication terminal of the user not to be able to generate the avoiding path. Furthermore, the controlling is executed based on an instruction for automated traveling from the communication terminal.
