Blind Spot Display Device with Traveling State-Based Image Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blind spot display devices may distract drivers with unnecessary image displays, leading to decreased attentiveness during driving, as they do not effectively control image display based on the vehicle's traveling state.
Innovation Solution
A blind spot display device with image display units inside vehicle pillars and attention drawing units that switch display and non-display based on the vehicle's traveling state, ensuring images are only shown when necessary, using a traveling state estimation unit to determine when to display or hide images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blind spot display device displays images continuously regardless of traveling state, then the driver can check blind spot images at any time, but the driver may experience visual distraction and decreased attentiveness during driving
Solution Approach 1:
The display device dynamically adjusts its operation based on the vehicle's traveling state. The control unit receives signals from the traveling state estimation unit and switches between display modes (first display mode showing both blind spot images, second display mode showing only necessary blind spot image, third display mode not showing blind spot images) based on whether the vehicle is moving, stationary, or in specific traveling conditions. This dynamic adaptation ensures images are available when needed while preventing distraction during stable driving conditions.
2Reliability
If the blind spot display device displays images only when necessary based on traveling state, then visual distraction is reduced, but the driver may miss important blind spot information at inappropriate timing
Solution Approach 1:
The traveling state estimation unit continuously monitors vehicle conditions in advance to determine when blind spot images should be displayed. By proactively identifying traveling states that require blind spot awareness (such as low-speed movement, stationary conditions, or specific directional changes), the system prepares to display images before the driver needs to check blind spots, ensuring timely information availability without requiring driver initiative.
Solution Approach 2:
The control unit receives continuous feedback from the traveling state estimation unit about the vehicle's current state and adjusts display behavior accordingly. This closed-loop control ensures that blind spot images are displayed precisely when the traveling state indicates potential hazard or maneuvering conditions, and suppressed when driving conditions are stable and safe, optimizing both responsiveness and distraction prevention.
3Loss of information
If both image display units are always in display state, then complete blind spot coverage is provided, but unnecessary images may distract the driver
Solution Approach 1:
The display system applies different display qualities to different sides based on the vehicle's traveling state. When the vehicle is moving in a specific direction or under certain conditions, only the blind spot image relevant to that direction is displayed (second display mode), while the other side remains suppressed. This localized display approach ensures complete coverage when needed while eliminating distracting unnecessary images from specific locations based on current driving context.

AI summary
Disclosed is a blind spot display device which enables a driver to check the image of a blind spot area at required timing and can prevent the visual distraction of the driver due to display of unnecessary images, ensuring that the driver is sufficiently attentive during driving. On the basis of the traveling state of a vehicle estimated by a traveling state estimation section, a right display and a left display switch display and non-display of the image of the blind spot area, and the right attention drawing section or the left attention drawing section corresponding to the display displaying the image draws the attention of the driver. On the basis of the traveling state, the image is displayed only when necessary, and is not displayed when unnecessary.
