Automated Valet Parking Control for White-Line Crossing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated valet parking systems face challenges when a vehicle needs to be parked across a white line, as existing systems may not allow for this, leading to the inability to implement automated valet parking.
Innovation Solution
The system sets two distinct movement permission areas: one for autonomous traveling that does not include the target parking space, and another for automated valet parking that includes the target parking space and surrounding areas, allowing the vehicle to park across a white line if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the boundary or area where the vehicle can travel is strictly set based on the white line, then the parking rule compliance is improved, but the automated valet parking cannot be implemented
Solution Approach 1:
The movement permission area is dynamically adjusted based on the vehicle's state. When the vehicle is in autonomous traveling mode, the movement permission area is set to exclude the target parking space and allow travel along the traveling path. When the vehicle arrives near the target parking space or sends notification of start of automated valet parking, the movement permission area is changed to include the target parking space and part of the traveling path near the target parking space, enabling the vehicle to cross the white line for parking.
Solution Approach 2:
The system changes the parameters of the movement permission area based on different operational phases. The area definition transitions from a travel-oriented configuration (excluding target parking space) to a parking-oriented configuration (including target parking space), allowing the vehicle to legally cross the white line boundary when performing automated valet parking operations.
2Adaptability or versatility
If the movement permission area includes the target parking space during autonomous traveling, then the automated valet parking can be implemented, but the vehicle may incorrectly enter the parking space before ready
Solution Approach 1:
The movement permission area is dynamically adjusted based on the vehicle's state. When the vehicle is in autonomous traveling mode, the movement permission area is set to exclude the target parking space and allow travel along the traveling path. When the vehicle arrives near the target parking space or sends notification of start of automated valet parking, the movement permission area is changed to include the target parking space and part of the traveling path near the target parking space, enabling the vehicle to cross the white line for parking.

AI summary
The system includes a first movement permission area setting unit configured to set a movement permission area for autonomous traveling that includes a part of a traveling path along which the autonomous driving vehicle reaches the target parking space and does not include the target parking space, and a second movement permission area setting unit configured to, when it is determined that the autonomous driving vehicle has arrived near the target parking space or when notification of a start of the automated valet parking for the target parking space is sent from the autonomous driving vehicle, set a movement permission area for automated valet parking that includes the target parking space and a part of the traveling path near the target parking space.
