Parking Space Angle Correction for Faster Assisted Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking support apparatuses require the vehicle to move again after entering a parking space to correct the parking angle, leading to increased parking time.
Innovation Solution
A parking support apparatus that includes a first parking space setting unit, a second parking space setting unit, a parking space determination unit, and a parking route generation unit. The apparatus calculates a first parking space and a second parking space by correcting the parking angle, determines the reliability of the second parking space, and generates a parking route to the determined parking space, eliminating the need for the vehicle to move again after entering the parking space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle moves again after entering the parking space to correct the parking angle, then the parking angle accuracy is improved, but the parking time is increased
Solution Approach 1:
The system performs preliminary correction of the parking angle by recalculating the parking space information before the vehicle completes its parking maneuver. The control unit calculates corrected parking space information including a corrected parking angle based on the actual parking route, and then guides the vehicle to park at the corrected parking space, eliminating the need for post-parking angle correction movements.
Solution Approach 2:
The system uses feedback from the actual parking route execution to correct the parking space information. The control unit monitors the vehicle's parking route, calculates the deviation from the initial parking space, and generates corrected parking space information that incorporates this feedback, allowing for real-time adjustment without requiring additional corrective movements after parking.
2Measurement precision
If the parking route is recalculated after entering the parking space, then the parking position accuracy is improved, but the parking operation complexity is increased
Solution Approach 1:
The system performs the recalculation of the parking route and correction of parking space information before the vehicle completes its parking maneuver. By calculating the corrected parking space information in advance based on the actual parking route, the system eliminates the need for complex post-parking operations and multiple movement cycles.
Solution Approach 2:
The system maintains continuous calculation and adjustment of the parking route during the parking maneuver. The control unit continuously monitors the vehicle's position and adjusts the parking space information throughout the parking process, ensuring smooth and continuous correction without interrupting the parking operation or requiring the vehicle to move in and out of the parking space multiple times.

AI summary
A parking support apparatus includes: a first parking space setting unit that sets a first parking space including information of a parking position and a parking angle of a vehicle at a parking completion position; a second parking space setting unit that calculates a second parking space, which is obtained by correcting the parking angle of the first parking space, based on information of measurement of the first parking space by using a vehicle surrounding sensor which measures a surrounding area of the vehicle; a parking space determination unit that calculates reliability of the second parking space and determines to use the first parking space or the second parking space based on the calculated reliability; and a parking route generation unit that generates a parking route to the first parking space or the second parking space determined by the parking space determination unit.
