Parking Assist Overhead View for Teacher-Driven Route Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to objectively understand the positional relationship between the travel route of a vehicle based on teacher driving and objects and roads around the vehicle.
Innovation Solution
A parking assist method that includes acquiring images of the vehicle's periphery using imaging devices, recording the travel route, generating an enlarged overhead image of the display target range, and displaying this image on a display device to facilitate understanding of the positional relationship.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional parking assist technology is used to perform autonomous driving based on teacher driving, then the vehicle can automatically park in fixed positions, but users cannot objectively understand the positional relationship between the travel route and surrounding objects and roads
Solution Approach 1:
The patent transforms the conventional 2D planar display of travel routes into a 3D overhead view that shows the vehicle's position, travel route, and surrounding objects/roads in a top-down perspective. This dimensional change allows users to visually comprehend the spatial relationship between the vehicle path and environmental features, resolving the information loss problem while preserving autonomous parking functionality.
Solution Approach 2:
The patent introduces an overhead image display as an intermediary visual interface between the autonomous driving system and the user. This mediator presents processed visual information showing the vehicle's position, recorded travel route, and detected objects/roads, enabling users to understand the positional relationships without interfering with the automated parking execution.
2Loss of information
If detailed captured images are displayed to show positional relationships, then user understanding improves, but device complexity and processing requirements increase
Solution Approach 1:
The patent extracts only the essential visual information needed for user understanding from the full captured images - specifically the vehicle position, travel route trajectory, and key surrounding objects/roads. By selecting and displaying only these critical elements in an overhead view rather than showing complete detailed images, the system reduces processing complexity and display requirements while maintaining adequate user comprehension.
Solution Approach 2:
The patent applies different levels of detail to different regions of the display - the travel route area receives focused attention with clear positional markers, while surrounding areas show contextual objects and roads at appropriate detail levels. This localized quality adjustment optimizes information presentation without uniformly increasing overall system complexity.

AI summary
A parking assist method according to the present disclosure is for performing autonomous driving of a vehicle on the basis of teacher driving by a driver. The parking assist method includes acquiring, from an imaging device installed in the vehicle, captured images obtained by imaging periphery of the vehicle in time series according to movement of the vehicle during the teacher driving. The method includes recording a travel route of the vehicle in the teacher driving, and generating, on the basis of the captured images, a first enlarged overhead image of a display target range viewed from above. The display target range covers the travel route and a periphery of the travel route. The method further includes causing a display device to display the first enlarged overhead image.
