Vehicle Peripheral Image Display for Map-Free Position Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Peripheral monitoring devices that display peripheral images on vehicle displays face challenges when vehicles lack map data, require map enlargement for position identification, and experience repetitive screen display due to positioning inaccuracies, leading to driver frustration.
Innovation Solution
A peripheral monitoring device that uses cameras and sonars to capture images, associates registration positions with time-stamped images, and displays these images on a touch screen, allowing drivers to identify positions without map data and reducing repetitive display through wider range detection and threshold-based conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If map data is used to display registration positions, then position identification is enabled, but the system cannot be applied to vehicles without map data
Solution Approach 1:
The patent creates visual copies of the peripheral environment at registration positions by capturing images with photographing devices and displaying them on the display device. These image-based representations serve as substitutes for map data, allowing position identification without requiring actual map information. The system stores multiple images corresponding to different registration positions and retrieves appropriate images based on current vehicle position.
2Ease of operation
If map enlargement operation is required to identify registration positions, then position identification is possible, but driver operation becomes complex and time-consuming
Solution Approach 1:
The patent divides the display area into multiple regions, with each region showing a different peripheral image corresponding to a specific registration position. This segmentation allows the driver to view multiple registration positions simultaneously without requiring zoom or enlargement operations. The display device presents a segmented overview where each segment represents a different stored location, enabling quick visual identification and selection.
3Reliability
If the display device shows peripheral images frequently due to positioning inaccuracies, then position monitoring is enhanced, but driver frustration increases
Solution Approach 1:
The patent introduces a dead zone (second range) around each registration position where the peripheral screen is not displayed, even when the vehicle is detected within the monitoring range (first range). This local quality adjustment prevents excessive display activation in areas where the vehicle is merely passing by rather than actually needing peripheral monitoring. The system distinguishes between different zones: the first range for monitoring, the second range for suppressing display, and only activates when the vehicle truly needs attention.

AI summary
A peripheral monitoring device includes: a photographing device that is configured to photograph a peripheral area of a vehicle; and a control unit that is configured to display a peripheral screen including a predetermined peripheral image generated based on an image photographed by the photographing device, when a predetermined display condition is established.
