Parking Alignment Adjustment Using Sensor Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic parking assistance systems have complex operation procedures and limitations in parking space search performance, leading to unsatisfactory parking alignment due to sensor limitations and driver variability, making them less convenient and effective.
Innovation Solution
A parking alignment adjustment apparatus and method that uses sensors to determine if a vehicle is parked and calculates a target parking position based on surrounding environment information, allowing drivers to improve alignment by entering a command to adjust the vehicle's position after initial parking, using sensors like steering angle, speed, and ultrasonic or image sensors to control the vehicle's alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional automatic parking assistance systems are used, then parking assistance function is provided, but operation procedure is complicated and requires driver learning
Solution Approach 1:
The system performs automatic parking alignment adjustment without requiring driver intervention after initial parking. The control unit automatically detects parking completion and executes alignment correction based on sensor data, allowing the system to serve itself rather than requiring complex driver operations.
Solution Approach 2:
The system pre-calculates the target parking position and alignment correction path before the driver completes parking. By preparing the adjustment plan in advance and automatically executing it after parking detection, the system eliminates the need for complicated post-parking driver operations.
2Adaptability or versatility
If conventional automatic parking assistance systems are used, then parking assistance is provided, but parking space search performance is limited due to sensor limitations
Solution Approach 1:
The system combines multiple sensor types (ultrasonic sensors for distance measurement, image sensors for visual recognition, steering angle sensors for orientation) to overcome the limitations of individual sensors. This fusion of sensor data enables accurate parking space detection and target position calculation despite individual sensor constraints.
Solution Approach 2:
The control unit acts as an intermediary that processes and integrates data from multiple sensors, transforming raw sensor signals into accurate parking space identification and target position determination. The control unit mediates between limited sensor inputs and the required parking guidance output.
3Ease of operation
If driver manually parks the vehicle, then parking is completed based on driver judgment, but final parking alignment varies depending on driver concentration and conditions
Solution Approach 1:
The system continuously monitors parking status using sensors and provides feedback to the driver about the current alignment status. After parking completion, the control unit compares the actual position with the target position and automatically executes correction, ensuring consistent alignment regardless of driver variability.
Solution Approach 2:
The system replaces the driver's manual alignment adjustment operations with automatic control. The control unit substitutes the driver's concentration-dependent manual steering with automated steering control based on sensor feedback, eliminating variability caused by driver conditions.
4Manufacturing precision
If driver alights from vehicle to adjust parking state, then parking alignment may be improved, but this requires driver to get in and out of vehicle which is inconvenient
Solution Approach 1:
The system performs automatic alignment adjustment without requiring the driver to exit and re-enter the vehicle. The control unit autonomously detects parking completion, calculates the correction needed, and executes the alignment adjustment, allowing the system to self-correct rather than requiring driver intervention.
Solution Approach 2:
The system prepares the alignment correction plan in advance and automatically executes it after detecting parking completion. By having the adjustment ready and automatically implementing it, the system eliminates the need for inconvenient driver exit and re-entry operations.
