Vehicle Control Device Dynamic Detection Load for Valet Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems face challenges in safely approaching a user during valet parking, often requiring the vehicle to stop at a distance due to high collision probability, which limits its ability to get close to the user.
Innovation Solution
A vehicle control device and method that includes a detector to assess the vicinity situation and a controller to adjust the vehicle's speed and steering for approaching a user, while reducing the detection load by dynamically altering scan regions and scan cycles based on the presence of the user, allowing the vehicle to safely and efficiently approach the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle maintains high detection load to ensure safety, then collision avoidance capability is improved, but the vehicle cannot approach close to the user
Solution Approach 1:
The patent applies dynamics by making the detection load adjustable rather than fixed. The detection load is dynamically changed based on the vehicle's proximity to the user: high detection load is maintained when the vehicle is far from the user to ensure safety, and reduced when the vehicle approaches close to the user to enable closer positioning. This dynamic adjustment resolves the contradiction between maintaining collision avoidance capability and enabling close approach to the user.
2Length of moving object
If the vehicle reduces detection load to enable closer approach, then approach distance to user is improved, but safety monitoring capability deteriorates
Solution Approach 1:
The patent applies local quality by differentiating detection requirements in different spatial zones. When the vehicle approaches close to the user, the detection load is reduced specifically in regions where the user is not present, while maintaining or enhancing detection capability in regions where the user might be located. This localized adjustment allows the vehicle to reduce overall detection load for closer approach while preserving safety monitoring capability in critical areas.
3Area of stationary object
If the vehicle uses fixed scan regions for detection, then detection coverage is improved, but detection efficiency deteriorates when approaching user
Solution Approach 1:
The patent applies dynamics by making scan regions adjustable rather than fixed. The scan regions are dynamically modified based on the vehicle's approach state: when the vehicle is far from the user, larger scan regions are used to ensure comprehensive detection coverage; when the vehicle approaches close to the user, scan regions are reduced or adjusted to focus on critical areas, thereby improving detection efficiency while maintaining necessary coverage.
Solution Approach 2:
The patent applies segmentation by dividing the detection space into multiple regions with different detection requirements. Instead of uniformly scanning the entire detection area, the system segments the space and applies different detection strategies to different segments: full coverage in distant regions and focused scanning in near regions where the user is present. This segmentation improves detection efficiency by reducing redundant scanning while maintaining comprehensive coverage where needed.

AI summary
A vehicle control device includes a detector configured to detect a vicinity situation of a vehicle, a first controller configured to cause the vehicle to move to a position at which a user of the vehicle gets on or gets off the vehicle by controlling a speed and steering of the vehicle on the basis of the vicinity situation detected by the detector, and a second controller configured to reduce a detection load of the detector when the vehicle moves to the position as compared to when the vehicle does not move to the position.
