Gesture-Controlled Vehicle Repositioning for Double-Parked Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driver assistance systems fail to effectively address the challenges of moving a double-parked vehicle, leading to potential conflicts and discomfort when drivers attempt to push or move them, and there is a risk of collision with adjacent vehicles.
Innovation Solution
A driver assistance apparatus equipped with cameras and detectors that identify pre-designated gestures to control the vehicle's gear state and movement, and a method that uses collision warnings and position adjustments based on distance to avoid collisions with approaching vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a driver pushes a double-parked vehicle by hand to secure departure space, then the vehicle can be moved, but the driver experiences discomfort and potential conflict with the double-parked vehicle driver
Solution Approach 1:
The patent replaces the manual mechanical pushing action with an automated gesture recognition system. The camera captures hand gestures, the processor identifies push gestures, and the driving device automatically moves the vehicle without requiring physical contact. This substitution eliminates driver discomfort and potential conflicts while achieving the same goal of moving the double-parked vehicle.
2Productivity
If a driver pushes and moves a double-parked vehicle, then the vehicle position changes, but there is a risk of colliding with adjacent double-parked vehicles
Solution Approach 1:
The system continuously monitors the vehicle's movement through camera feedback and processor analysis. As the vehicle moves in response to a push gesture, the system tracks the position changes and can detect when the vehicle is approaching adjacent parked vehicles, providing real-time feedback to prevent collisions.
Solution Approach 2:
The system applies preliminary anti-action by detecting the presence of adjacent double-parked vehicles before movement begins. The camera and processor identify potential obstacles in advance, and the system prepares to adjust the movement trajectory or stop before a collision can occur, preventing the harmful effect rather than reacting to it.
3Adaptability or versatility
If the vehicle gear state is changed to move the vehicle, then the vehicle can be repositioned, but the system requires complex control mechanisms
Solution Approach 1:
The camera system serves multiple functions: it captures images for gesture recognition, monitors vehicle position during movement, and detects adjacent vehicles. The processor performs multiple tasks including gesture identification, movement calculation, and collision risk assessment. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall system complexity while maintaining versatile vehicle movement control.
Data Source
AI summary
Disclosed herein is a driver assistance apparatus including a camera which is installed in a vehicle, has a field of view around the vehicle, and is configure to acquire image data, and a controller including a processor configured to process the image data. The controller is configured to identify a gesture corresponding to a predesignated reference gesture based on the image data, and change a gear state of the vehicle and control a driving device of the vehicle to move the vehicle, based on identifying the gesture.
