Vehicle Image Overlay for Pre-Stop Obstacle Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle collision avoidance systems fail to effectively present drivers with critical information about potential obstructions before the vehicle comes to a stop, as they do not accurately detect and display objects within the pre-stop moving range, leading to inadequate collision prevention.
Innovation Solution
An image presentation device and method that acquires vehicle speed, calculates a pre-stop moving range, detects objects using sensors, and superposes the moving range and object positions on a screen, highlighting objects likely to overlap with the moving range more saliently than others, providing a clear visual warning to the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an image indicating braking range is superposed on a captured image without recognizing obstructions, then the presentation is simple and easy to implement, but the system cannot provide appropriate collision prevention assistance
Solution Approach 1:
The system segments the display information by separating obstruction detection results from the captured image, superposing detection results (such as bounding boxes or markers) directly on the image. This allows the system to maintain simplicity in implementation while adding valuable obstruction recognition functionality that improves collision prevention capability.
2Device complexity
If the system merely predicts moving direction and distance without considering pre-stop moving range, then the calculation is simple, but the system fails to provide appropriate collision prevention presentation
Solution Approach 1:
The system performs preliminary calculation of the pre-stop moving range based on current vehicle speed and braking characteristics before superposing obstruction information. This allows the system to accurately determine whether obstructions lie within the stopping distance, providing reliable collision prevention assistance while maintaining reasonable calculation complexity through pre-computed parameters.
3Ease of operation
If all detected objects are displayed with equal prominence, then the display is uniform and simple, but the driver cannot quickly identify critical collision risks
Solution Approach 1:
The system applies different display qualities to different obstructions based on their position relative to the pre-stop moving range. Obstructions within the stopping distance are displayed with higher prominence (such as different colors, larger markers, or flashing indicators) compared to those outside the range, enabling drivers to quickly identify critical risks while maintaining overall display simplicity.

AI summary
A vehicle speed acquiring unit acquires a vehicle speed. A moving range calculating unit calculates, based on the vehicle speed, a pre-stop moving range within which the vehicle may cover before coming to a stop. A sensor information acquiring unit acquires object detection information indicating a detected object, detected by a sensor, in the surroundings of the vehicle. An image superposing unit superposes the pre-stop moving range and the position of the detected object included in the object detection information on top of each other on a screen. In addition, the image superposing unit generates a superposed image that displays the position of a detected object estimated, based on position information of the detected object included in the object detection information, to have a possibility of overlapping the pre-stop moving range, more saliently than the positions of other detected objects. An image presenting unit presents the generated superposed image.
