Intersection Surround View Display Triggered by Reduced Field of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle surrounding monitoring systems display surrounding images unnecessarily when approaching a traffic intersection, causing driver discomfort due to reduced field of view, especially when buildings obstruct the view on either side of the vehicle.
Innovation Solution
A vehicle surrounding monitoring apparatus that displays surrounding images only when the vehicle approaches a traffic intersection and the field of view is reduced, using image acquisition and control units to determine the appropriate conditions, such as distance and road signs, to activate image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the surrounding image is continuously displayed by the displaying device, then the driver can obtain information on blind areas, but the driver may feel bothersome
Solution Approach 1:
The system dynamically adjusts the display state of the surrounding image based on real-time detection of field of view conditions. The electronic control unit continuously monitors whether the field of view condition is satisfied and activates the displaying device only when necessary, transitioning between display and non-display states according to changing driving conditions, thereby providing information only when the driver actually needs it.
Solution Approach 2:
The system uses the field of view value as a threshold parameter to control display activation. When the calculated field of view value falls below a predetermined threshold, indicating restricted visibility, the system triggers the display of the surrounding image. This parameter-based control ensures the display is activated only under conditions where the driver's natural field of view is insufficient.
2Reliability
If the surrounding image is displayed when the field of view is low, then the driver can see blind areas, but the surrounding image may be unnecessarily displayed when field of view is sufficient
Solution Approach 1:
The electronic control unit continuously calculates the field of view value based on current driving conditions and uses this feedback to control the displaying device. The system monitors the field of view condition in real-time and adjusts display activation accordingly, ensuring the surrounding image is displayed only when the field of view condition is satisfied, thereby avoiding unnecessary energy consumption while maintaining reliable visibility when needed.

AI summary
A vehicle surrounding monitoring apparatus comprises an image acquisition device which acquires a surrounding image corresponding to an image of a view around an own vehicle, and a displaying device which displays the surrounding image. The vehicle surrounding monitoring apparatus displays the surrounding image by the displaying device when the own vehicle has approached a traffic intersection, and a displaying condition becomes satisfied. The displaying condition corresponds to a condition that a field-of-view value is equal to or smaller than a predetermined field-of-view value. The field-of-view value corresponds to a value which represents a field of view from the own vehicle to the traffic intersection.
