Parking Assistance Device Automatic Stall Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assistance devices require user intervention to select a target parking position, placing a burden on the driver and increasing the complexity of the parking process.
Innovation Solution
A parking assistance device that includes a ground object detection unit, a parking stall calculation unit, and a target parking stall setting unit, which automatically sets a target parking stall based on detected ground objects and vehicle dimensions, allowing for intuitive and burden-free parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple target parking positions are detected and the user is prompted to select, then the parking assistance device can handle complex parking scenarios, but the user burden increases due to required operations
Solution Approach 1:
The system performs automatic selection of target parking positions based on pre-set criteria (width direction from driver's seat) without requiring user intervention. The control unit automatically determines which parking stall to use among multiple detected options, making the system self-serve the selection function that would otherwise require user input.
2Ease of operation
If automatic target parking stall selection is implemented, then user burden is reduced, but the system complexity increases
Solution Approach 1:
The patent replaces manual user selection operations with an automated control system that uses image processing and logical rules to select parking positions. The control unit substitutes the mechanical interaction of user pressing buttons or making selections with an automated computational process based on detected parking stall positions and pre-set selection criteria.
3Productivity
If the detection region is set on the lateral side of the vehicle, then the system can detect parking stalls efficiently, but the detection region size is constrained
Solution Approach 1:
The system concentrates detection resources on the lateral side of the vehicle where parking stalls are most relevant for garage parking maneuvers. By setting the detection region specifically on the lateral side rather than attempting to detect all possible parking positions in all directions, the system achieves efficient detection of relevant parking stalls with an optimized, focused detection area.

AI summary
Provided is a parking assistance device capable of setting a parking target position without placing a burden on a driver. The parking assistance device includes: a ground object detection unit configured to detect a ground object that defines a parking stall in a predetermined detection region set in advance on a lateral side of a vehicle; a parking stall calculation unit configured to, based on the ground object detected by the ground object detection unit, calculate a parking stall that exists in the detection region; and a target parking stall setting unit configured to, among the parking stalls calculated by the parking stall calculation unit, sets a parking stall in a width direction of the vehicle in a view from a driver's seat of the vehicle as a target parking stall.
