Vehicle Surroundings Display Device with Direction Indicator Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle surroundings display systems switch displays at unintended times when the direction indicator state changes, affecting the ease of driving operations, particularly during turns or changes in direction.
Innovation Solution
A vehicle surroundings display device with an imaging system and display controller that shows a wider area when the direction indicator is active and reverts to a standard view after a standby duration when inactive, adjusting this duration based on vehicle speed and location to prevent unintended display switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the display switches immediately when the direction indicator transitions from active to inactive state, then the display responsiveness is improved, but the ease of driving operation deteriorates due to unintended display switches during turns
Solution Approach 1:
The display controller sets a standby duration period after the direction indicator transitions from active to inactive state before switching the display back to the first predetermined area. This preliminary waiting period prevents immediate switching that would occur during temporary steering corrections, thereby avoiding unintended display switches while maintaining reasonable responsiveness
Solution Approach 2:
The display switching behavior is made dynamic by introducing a time-based standby duration parameter. The display does not switch immediately but waits for a predetermined period, allowing the system to adapt to temporary direction indicator deactivations during turns while still switching back when the indicator remains inactive for the full standby duration
2Loss of information
If the display shows a wider area during direction changes, then the driver's awareness of surroundings is improved, but the device complexity increases due to multiple display modes and switching logic
Solution Approach 1:
The display area is segmented into two predetermined areas: a first predetermined area for normal display and a second predetermined area for wider view during direction changes. The display controller selectively switches between these two segmented display areas based on direction indicator state, providing enhanced awareness while maintaining manageable complexity through clear area segmentation
Solution Approach 2:
The display system serves multiple functions by showing different predetermined areas based on driving conditions. The same display device universally handles both normal viewing (first predetermined area) and enhanced surroundings awareness (second predetermined area) through conditional switching logic, eliminating the need for separate display systems

AI summary
A vehicle surroundings display device is provided. The vehicle surroundings display device includes an imaging device, a display device, and a display controller. The imaging device images a region toward a rear side of a vehicle and sideways from the vehicle. The display device is capable of displaying an image captured by the imaging device. The display controller displays a first predetermined area of the image as a first display image on the display device in cases in which a direction indicator of the vehicle is in an inactive state, displays a second predetermined area of the image corresponding to an activated side of the direction indicator as a second display image on the display device in cases in which the direction indicator has transitioned from an inactive state to an active state, the second predetermined area being wider than the first predetermined area and including the first predetermined area, and switches a display on the display device from the second display image to the first display image after a predetermined standby duration has elapsed when the direction indicator has transitioned from an active state to an inactive state.
