Automatic Parking Control Device Frame Reachability Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic parking control devices face challenges in accurately guiding vehicles to a target parking position without relying on full route regeneration, especially when external environment recognition errors or changes cause deviations from the intended route.
Innovation Solution
An automatic parking control device with a determination unit, calculation unit, and adjustment unit that assesses whether the vehicle can reach the next frame by adjusting the steering angle and travel direction, allowing for a light-load adjustment route to be generated without full route regeneration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full route regeneration is performed when the vehicle deviates from the parking route, then the vehicle can reach the target parking position with high reliability, but the processing time increases and the vehicle may need to stop
Solution Approach 1:
The patent segments the parking route into multiple section routes, each extending from a turning position to a next turning position or target parking position. This allows the system to perform feedback control and deviation determination on individual section routes rather than regenerating the entire parking route, significantly reducing processing time while maintaining arrival accuracy at each section endpoint
Solution Approach 2:
The patent performs preliminary determination of whether the vehicle can reach the next frame before actual vehicle control. The determination unit assesses reachability based on current vehicle position, section route information, and external environment recognition results, allowing proactive adjustment before significant deviation occurs, thereby reducing the need for time-consuming full route regeneration
2Manufacturing precision
If normal route generation processing is applied to various positional relations, then the parking route can be generated accurately, but the processing becomes complicated and time-consuming
Solution Approach 1:
The patent applies different control strategies to different section routes based on their specific characteristics. The determination unit evaluates reachability to the next frame for each section route individually, allowing the system to simplify processing for sections where the next frame is clearly reachable while maintaining rigorous processing only where needed, thus reducing overall complexity without sacrificing accuracy
3Measurement precision
If feedback control is applied to make the vehicle travel on the parking route, then the vehicle can follow the calculated route, but accumulation of errors may cause the end position to deviate from the next frame
Solution Approach 1:
The patent implements a determination unit that continuously monitors whether the vehicle can reach the next frame based on current position, section route information, and external environment recognition. This feedback mechanism detects potential arrival failures before they occur, allowing the system to proactively determine reachability and adjust control strategies, preventing error accumulation from causing missed frames

AI summary
Provided is an automatic parking control device capable of causing a vehicle to correctly reach the next frame, without relying on normal parking route regeneration, when a determination is made that the vehicle cannot reach the next frame under automatic parking vehicle control along a section route constituting a part of a parking route. When a determination is made whether the next frame is located on an extension of the current section route and the determination result shows that the next frame is located on the extension, the host vehicle is caused to further travel, or when the determination is made whether the next frame is located on a remaining section of the current section route and the determination result shows that the next frame is located on the remaining section, the host vehicle is caused to decelerate earlier, thereby allowing the host vehicle to reach and come to a stop at the next frame.
