Automatic Parking Control Using Vehicle Motion History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking support apparatuses struggle to perform automatic parking efficiently, as they require manual confirmation of the parking position and do not effectively utilize the vehicle's surroundings for parking slot detection.
Innovation Solution
A parking support apparatus equipped with a processor that detects parking slots based on surrounding images and stores a history of vehicle operations and movements to automatically detect parking instructions and perform smooth automatic parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual confirmation of parking position is required, then parking accuracy is improved, but parking time increases
Solution Approach 1:
The parking support apparatus automatically detects parking instructions by analyzing the history of vehicle operations and movements without requiring manual confirmation from the driver. The system self-determines the parking position based on detected parking slots and vehicle state history, enabling automatic parking execution that reduces time loss while maintaining accurate parking position detection through image processing of parking slot boundaries
Solution Approach 2:
The system continuously monitors and stores the history of vehicle operations (acceleration, deceleration, steering) and movements (position, speed) to detect parking instructions. This feedback mechanism allows the apparatus to automatically recognize when the driver intends to park by analyzing patterns in the stored history data, eliminating the need for manual confirmation while ensuring accurate parking position detection
2Device complexity
If parking slot detection uses basic image processing, then system complexity is reduced, but detection precision deteriorates
Solution Approach 1:
The image processing system segments the captured image into multiple regions corresponding to different parking slots by detecting boundary lines. The processor divides the parking area into individual slot regions based on detected white lines, allowing precise identification of available parking slots without requiring complex overall scene understanding, thus maintaining relatively simple system architecture while achieving accurate detection

AI summary
A parking support apparatus includes an instruction detection section that detects the occupant's parking instruction based on an operation of the occupant of the vehicle or a history of a motion of the vehicle, and a vehicle control section that performs the automatic parking of the vehicle. When the history indicates that the vehicle has stopped after steering and turning from a straight movement, and that the occupant has performed a predetermined parking instruction operation, the instruction detection section determines that the parking instruction is detected.
