Parking Support Apparatus Using Pre-Recorded Path for Reliable Auto Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking support apparatuses face challenges in automatically moving a vehicle to a registered parking position, especially when the vehicle encounters difficult-to-travel areas, as the imaging device may not capture these obstacles, leading to failed automatic parking control.
Innovation Solution
The apparatus includes an imaging device for capturing peripheral data, an instruction device for generating signals, a control device for performing automatic parking, and a memory for storing registered positions, allowing for the determination of a first determination position during automatic parking control and subsequent use as a registered position, reducing the likelihood of failed automatic parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver manually drives the vehicle to register a parking position, then the parking position can be registered, but the vehicle may encounter difficult-to-travel areas that are not captured by the imaging device, leading to failed automatic parking control
Solution Approach 1:
The system performs preliminary action by having the driver manually drive the vehicle to the target parking position and store the generated target path in advance. This pre-recorded path information is then used during automatic parking control to guide the vehicle, ensuring that the vehicle follows a previously verified safe route that avoids difficult-to-travel areas not detectable by the imaging device.
2Extent of automation
If the imaging device is positioned for automatic parking control, then the control can be performed, but the imaging device may not photograph difficult-to-travel areas, causing the target path to include uncaptured obstacles
Solution Approach 1:
The system introduces an intermediary element - the pre-recorded target path generated during manual driving. This target path serves as a mediator that bridges the gap between the limited imaging device coverage and the complete navigation requirements. The path is stored in memory and used during automatic parking control to guide the vehicle along a previously verified safe route, compensating for the imaging device's inability to detect certain obstacles.
3Ease of operation
If the vehicle is moved manually to avoid difficult areas, then the driver can navigate obstacles, but the automatic parking control cannot replicate this avoidance behavior
Solution Approach 1:
The system applies copying by recording the target path generated during manual driving - the very path that successfully avoided difficult-to-travel areas - and storing it in memory. During automatic parking control, the vehicle follows this copied path information, replicating the successful navigation strategy without requiring real-time imaging detection of obstacles that were avoided during the manual path creation phase.

AI summary
When an automatic parking registration method is selected, a vehicle control ECU performs a pre-registration automatic parking control and stores a position determined based on a position of a vehicle at a time point at which the vehicle is set to a stop state by the pre-registration automatic parking control as a registered parking position in a non-volatile memory. When an execution condition of a post-registration automatic parking control is satisfied, the vehicle control ECU performs the post-registration automatic parking control after setting a target parking position to registered parking position which has been stored in the non-volatile memory.
