Vehicle Perimeter Display Controller with Conditional Obstacle Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing systems for vehicles often unnecessarily notify drivers of obstacles, disrupting operations and failing to provide timely notifications when required.
Innovation Solution
An image processing device with a display controller and determining unit generates a synthesized image of a vehicle's perimeter from a virtual viewpoint and switches to a notification screen only when specific conditions are met, such as the absence of navigation device operation, ensuring appropriate obstacle notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If display switching is performed every time an obstacle is detected, then the driver is notified of all obstacles, but unnecessary notifications are provided that disrupt driver operations
Solution Approach 1:
The system changes the notification parameter from binary (notify/notify) to conditional (notify/hold) based on detected parameters such as vehicle speed, steering angle, and obstacle distance. When the vehicle is stationary or moving slowly with the steering wheel in neutral position, notification is enabled. When the vehicle is in active operation, notification is held to avoid disruption.
Solution Approach 2:
The notification system transitions from a static always-on approach to a dynamic conditional approach. The determining unit continuously monitors vehicle state parameters and dynamically adjusts whether obstacle notification should occur, creating a flexible system that adapts to current driving conditions rather than following a fixed notification rule.
2Loss of information
If the conventional apparatus notifies the driver of all detected obstacles, then comprehensive safety information is provided, but the notification system cannot appropriately distinguish when notification is required
Solution Approach 1:
The system implements feedback by continuously monitoring vehicle operation parameters (speed, steering angle) and using this information to determine whether obstacle notification is appropriate. The determining unit receives feedback from the vehicle state and adjusts the notification behavior accordingly, creating a closed-loop system that improves notification appropriateness while maintaining obstacle detection completeness.
3Loss of information
If display switching is performed frequently, then all obstacles are communicated to the driver, but operational efficiency is reduced due to unnecessary display changes
Solution Approach 1:
The system changes the display switching parameter from frequent unconditional switching to conditional switching based on vehicle state parameters. By evaluating parameters such as vehicle speed and steering position, the system determines when display switching is appropriate, thereby maintaining obstacle information communication while eliminating unnecessary display changes that reduce operational efficiency.

AI summary
An image processing device according to an aspect of the embodiment includes a display controller and a determining unit. The display controller generates a synthesized image when viewing a perimeter of a vehicle from a virtual viewpoint based on an image from an image capturing device and causes a display unit to display the synthesized image. The determining unit determines, in a case where a screen other than a virtual viewpoint screen including the synthesized image is displayed on the display unit, whether a switching condition to a notification screen for notifying an occupant of presence of an obstacle is satisfied when the obstacle is detected by a detector. The display controller causes the display unit to display the notification screen obtained by superimposing a predetermined notification image on the virtual viewpoint screen, when the determining unit determines that the switching condition is satisfied.
