Innovation Solution
A smart parking assist apparatus and method using imaging devices and ultrasonic sensors to search for a parking slot, recognize the parking line, and set a parking reference line after the vehicle stops, allowing for one-time input to initiate parking and reducing the complexity of parking maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple switch manipulations are required to select parking modes and directions, then parking control precision is improved, but driver convenience deteriorates
Solution Approach 1:
The system automatically detects parking slots and determines parking modes and directions without requiring driver input. The imaging device captures images of the surrounding environment, and the controller automatically processes these images to identify parking slots and set parking parameters, making the system serve itself rather than requiring continuous driver intervention.
Solution Approach 2:
The system performs preliminary detection and analysis of parking slots before the actual parking maneuver. The imaging device captures images in advance, the controller processes these images to identify parking slots and determine parking modes, and prepares the parking reference line before the vehicle begins moving, so that when parking is initiated, all parameters are already determined.
2Measurement precision
If the vehicle moves forward to scan for parking slots using ultrasonic sensors, then parking slot detection accuracy is improved, but the number of movements and time required increases
Solution Approach 1:
The system replaces the mechanical scanning method (moving the vehicle forward while ultrasonic sensors search for parking slots) with an optical imaging method. The imaging device captures images of the surrounding environment while the vehicle is stationary, and the controller processes these images to detect parking slots, substituting mechanical movement with optical detection and image processing.
Solution Approach 2:
The system performs preliminary detection of parking slots using the imaging device before the vehicle moves. The controller processes images to identify parking slots and determines parking parameters in advance, so that when the parking maneuver begins, all detection and analysis work is already completed, eliminating the need for forward scanning movements.
3Reliability
If parking control starts after the vehicle passes the parking slot by a predetermined distance, then parking safety is improved, but parking efficiency deteriorates
Solution Approach 1:
The system performs preliminary detection and determination of parking slots and parking parameters before the vehicle moves. The controller identifies parking slots, determines parking modes and directions, and sets the parking reference line in advance using image processing, so that when the parking maneuver begins, all control parameters are already prepared, allowing immediate execution without waiting for the vehicle to pass a certain distance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system simplifies the parking process by allowing the vehicle to be parked with reduced movements and time, improving driver convenience by enabling parking slot selection and control without the need for multiple switch manipulations and forward scanning, thus enhancing parking accuracy and efficiency.
Implementation Method 1
searching a parking slot using imaging devices (e.g., camera, video cameras, and the like)
Implementation Method 2
recognizing a parking line of the target parking slot and an object adjacent to the target parking slot
Data Source
AI summary
A smart parking assist apparatus and method are provided. The smart parking assist apparatus operates a smart parking assist function after a vehicle stops and searches a parking slot using a plurality of imaging devices. In addition, the searched parking slot is set to a target parking slot and parking slot information regarding the target parking slot is output. The apparatus recognizes a parking line of the target parking slot and an object adjacent to the target parking slot and sets a parking reference line based on the recognized information, after the parking slot information is output. The vehicle is then operated to be parked in the target parking slot based on the parking reference line.
