Parking Assist Control for Relocating to a Forward Adjacent Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems do not facilitate easy and safe exit from a parking space, particularly when a second available parking space is present in front of the initially parked vehicle, as they primarily focus on forward parking without considering the possibility of moving to a more favorable parking position.
Innovation Solution
A parking assistance apparatus that includes a detection section to identify allowed parking spaces and a control section to manage the vehicle's movement, allowing it to transition from a first parking space to a second available space in front, enabling backward parking and easier exit through forward movement, with features like image detection, feature point recognition, and occupant input for decision-making.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle is forward parked in the first parking space, then the vehicle can be parked in the detected parking space, but the vehicle cannot easily exit the parking space when a second parking space is available in front
Solution Approach 1:
The parking assistance apparatus dynamically adjusts the parking strategy based on real-time detection of available parking spaces. When a second parking space is detected in front of the vehicle, the control section automatically initiates a relocation maneuver, transforming the static parking decision into a dynamic, adaptive process that optimizes exit ease.
Solution Approach 2:
The detection section performs preliminary detection of parking spaces before the vehicle completes parking in the first space. By identifying the second parking space in advance, the system can proactively plan and execute the relocation maneuver before the vehicle is fully stationary, making the subsequent exit operation easier.
2Reliability
If the vehicle remains in the first parking space, then the parking operation is completed, but the occupant cannot confirm surroundings easily when exiting
Solution Approach 1:
Instead of exiting directly from the first parking space with limited visibility, the vehicle first relocates to the second parking space where the exit orientation provides better surrounding visibility. This inverts the traditional exit sequence by using an intermediate parking position to improve safety confirmation before final exit.
3Productivity
If the control section only manages forward parking in the detected space, then the parking function is simple, but the system cannot optimize parking position for easier exit
Solution Approach 1:
The control section is designed with multi-functionality, handling both initial forward parking and subsequent relocation maneuvers. This universal control capability allows the system to perform multiple parking-related functions using the same detection and control infrastructure, optimizing the parking operation efficiency while enabling easier exit through strategic repositioning.

AI summary
A parking control method includes: detecting a first parking space based on the ambient image of the vehicle captured by an imaging device; controlling at least a steering actuator of the vehicle to cause the vehicle to be parked in the first parking space; detecting a second parking space based on the ambient image of the vehicle captured by the imaging device, while the vehicle is travelling into the first parking space, the second parking space being adjacent to the first parking space in a travelling direction of the vehicle, the second parking space being farther than the first parking space from the vehicle; and controlling at least the steering actuator of the vehicle to cause the vehicle to be parked in the second parking space.
