Autonomous Parking Repositioning for Close Parallel Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency in using parking spaces due to the requirement of maintaining a standard minimum distance between vehicles without autonomous driving systems, which restricts closer parking and utilization of space.
Innovation Solution
A method and system where a vehicle with autonomous driving capabilities detects an unlock signal from a nearby vehicle, determines if they are parked parallel and closely together, and autonomously adjusts its position to allow the driver of the other vehicle to enter and exit, thereby enabling closer parking without violating standard distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicles are parked at a regular distance from each other to allow driver entry and exit, then driver safety and ease of operation are improved, but parking space utilization deteriorates
Solution Approach 1:
The system dynamically adjusts the parking arrangement by having the second vehicle temporarily move out of its parked position when the first vehicle needs to be accessed. This dynamic adjustment allows the system to maintain close parking spacing while still enabling driver entry and exit when needed, resolving the contradiction between space utilization and operational ease.
Solution Approach 2:
The second vehicle autonomously detects the unlock signal from the first vehicle and automatically determines whether to move out to allow access. This self-service mechanism eliminates the need for manual coordination between drivers, enabling the system to automatically optimize parking space utilization while ensuring driver safety and ease of operation.
2Area of stationary object
If vehicles with autonomous driving systems park closer together to improve space utilization, then parking space efficiency is improved, but accessibility for drivers of non-autonomous vehicles deteriorates
Solution Approach 1:
The system maintains close parking spacing as a default state to maximize space efficiency, but dynamically adjusts by having the second vehicle move out when accessibility is needed. This dynamic behavior allows the system to achieve both goals: high space utilization during normal parking and improved accessibility when drivers need to enter or exit their vehicles.
Solution Approach 2:
The second vehicle is positioned in advance at a closer parking distance to optimize space utilization. When an unlock signal is detected, the system performs the preliminary action of moving the second vehicle out to allow access, ensuring that space efficiency is maintained during the majority of parking time while accessibility is provided when needed.
3Ease of operation
If the second vehicle moves out to allow driver entry into the first vehicle, then driver accessibility is improved, but the time required for parking and space utilization deteriorates
Solution Approach 1:
The system uses periodic monitoring of unlock signals to determine when accessibility is needed. The second vehicle remains in its close parking position continuously, and only temporarily moves out when an unlock signal is detected. This periodic action minimizes the time the vehicle is out of position, thereby reducing the impact on parking time while ensuring accessibility when needed.
Solution Approach 2:
The second vehicle quickly moves out of its parked position only when necessary to allow driver access, and then promptly returns to its original position. This rushing through the accessibility provision minimizes the time lost due to vehicle movement, allowing the system to maintain high space utilization while still providing necessary driver accessibility.

AI summary
A method for driving autonomously out of a parked position by a vehicle is provided. It comprises the steps of: a) detecting an unlock-signal for unlocking a central locking system of a first vehicle parked at a first position by a second vehicle parked at a second position; b) determining whether the two vehicles are parked parallelly and directly next to each other; c) if so, driving the second vehicle autonomously at least partly out of the second position; d) determining whether the first vehicle has left at least partly said first position; and, e) if so, driving the second vehicle autonomously back in said second position.
