Parking Pilot System Using Image and Distance Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in parking due to the complexity of navigating and determining suitable parking spaces, leading to inefficiencies and potential traffic issues, as existing technologies primarily rely on image detection and do not automatically measure parking spaces or provide optimized paths for different parking modes.
Innovation Solution
A parking pilot method and device that captures images, detects vehicle speed and distance to barriers, evaluates parking lot suitability, and provides optimized pilot frames for various parking modes, guiding the vehicle to an initial position and outputting operation instructions for manual or automatic steering control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a driver manually parks the vehicle by observing surroundings and controlling the steering wheel, then the driver can park the vehicle, but the parking process becomes time-consuming and laborious
Solution Approach 1:
The patent replaces the manual mechanical parking operation with an automated pilot system that uses image capture units, processors, and control devices to automatically measure parking space dimensions, calculate optimal parking trajectories, and control the vehicle's steering and movement, thereby significantly reducing parking time and labor
Solution Approach 2:
The system enables the vehicle to park itself by automatically detecting parking spaces, calculating parking parameters, generating pilot frames, and executing parking maneuvers without requiring continuous manual intervention from the driver, allowing the vehicle to perform the parking function autonomously
2Ease of operation
If the system provides only auxiliary vehicle-backing lines, then the system structure remains simple, but the driver still has to back the car manually and cannot park fast and accurately
Solution Approach 1:
The patent replaces simple visual aid lines with a comprehensive automated pilot system that integrates image capture, processing, trajectory calculation, and automated steering control, transforming the system from a passive display function to an active automated control system that handles the entire parking process
3Adaptability or versatility
If the system uses only image detection to recognize the environment, then the detection method remains simple, but the system cannot automatically measure parking space or provide optimized pilot paths
Solution Approach 1:
The patent creates a multi-functional system where the image capture units serve multiple purposes: detecting parking spaces, measuring dimensions, identifying barriers, and providing visual feedback, while the processor performs multiple functions including image processing, trajectory calculation, and control signal generation, enabling the system to handle various parking modes universally
Solution Approach 2:
The patent replaces simple image detection with an integrated detection and measurement system that uses image processing algorithms to automatically calculate parking space dimensions, determine optimal parking trajectories, and generate pilot frames for different parking scenarios, thereby enhancing system versatility
Data Source
AI summary
A parking pilot method and a device thereof are disclosed. Image detectors capture surrounding images of a vehicle. A speed detector detects speed of the vehicle. A distance detector obtains distance between the vehicle and a barrier. A processor obtains relative coordinates of the vehicle and parking lot and the angle and width of the parking lot with the images, speed and distances. Thereby, the processor creates a preset parking pilot frame and works out a relative position of the preset parking pilot frame and the parking lot. Then, the processor designates the preset parking pilot frame and the parking lot on a display. According to the information on the display, the driver moves the vehicle to an initial position and makes the preset parking pilot frame coincide with the parking lot. Then, the processor instructs the driver to manually park the vehicle, or automatically parks the vehicle.
