Remote Parking Assistance With Autonomous Park-or-Exit Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems cannot remotely control vehicles for both forward and reverse parking directions, limiting their functionality and user convenience, especially when exiting a parking space.
Innovation Solution
A remote-controlled parking assistance system that includes a receiver device for selecting movement directions and a control device capable of autonomously determining parking situations, allowing vehicles to park or exit in either forward or reverse directions based on the parking space position, using a decision logic that considers user input and vehicle position changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system always interprets forward travel as parking and reverse travel as parking-space-exiting, then the control logic is simple, but the system cannot perform reverse parking
Solution Approach 1:
The control device autonomously determines whether a parking situation or parking-space-exiting situation is present based on stored position data and received movement directions, without requiring explicit user specification. This self-service approach enables the system to handle both forward and reverse parking while maintaining simple user interaction.
Solution Approach 2:
The system stores the vehicle's starting position and continuously compares it with the current position to determine the operational mode. This feedback mechanism allows the system to automatically adapt its behavior based on the vehicle's movement relative to the stored position, enabling versatile parking operations without complex control logic.
2Ease of operation
If the system requires explicit user specification of parking situation, then the control precision is high, but the ease of operation decreases
Solution Approach 1:
The control device automatically determines the operational situation (parking or parking-space-exiting) by comparing the vehicle's current position with the stored starting position and analyzing the received movement directions. This eliminates the need for explicit user specification while maintaining accurate situation detection through automated position-based logic.
3Productivity
If the vehicle moves in unsteered fashion in reverse, then the device complexity is low, but the productivity of reverse parking is zero
Solution Approach 1:
The system dynamically adjusts its control behavior based on the determined operational situation. When a parking situation is detected, the system activates steered vehicle movement to enable precise reverse parking. When a parking-space-exiting situation is detected, the system uses unsteered movement. This dynamic adaptation enables reverse parking capability while maintaining simple control architecture.

AI summary
A parking assistance system is remote-controlled for automated parking and exiting from a parking space. The parking assistance system has a receiver for receiving a movement direction of the vehicle selected by the user. A control device which is coupled to the receiver is configured to decide independently, without the user making any specification about the presence of a parking situation or parking-space-exiting situation, whether there is a parking situation or parking-space-exiting situation. If the control device decides that the parking situation is present, the vehicle is parked in the parking space in accordance with the received selected movement direction by forward driving or driving in reverse. Otherwise, if the control device decides that the parking-space-exiting situation is present, the vehicle is made to exit the parking space in accordance with the received selected movement direction by forward driving or driving in reverse.
