Vehicle Image Overlay for Pre-Stop Collision Risk Highlighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for presenting drivers with the conditions surrounding their vehicles do not effectively assist in avoiding collisions with obstructions before the vehicle comes to a stop, as they fail to recognize and appropriately present obstructions within the vehicle's pre-stop moving range.
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 pre-stop moving range and object positions on a screen, highlighting objects likely to overlap with the pre-stop moving range more saliently than others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an image indicating braking range is superposed on captured image without obstruction recognition, then the presentation is simple and easy to implement, but the ability to provide appropriate collision prevention assistance is insufficient
Solution Approach 1:
The system segments the display information by separating obstruction detection data from braking range calculation data. Obstruction recognition results are processed independently and then integrated with the braking range overlay, allowing each function to be optimized separately while maintaining overall system reliability for collision prevention
Solution Approach 2:
The system performs preliminary obstruction recognition and analysis before superposing the braking range image. By detecting and analyzing obstructions in advance, the system can provide more accurate and timely collision prevention assistance while maintaining a manageable implementation complexity
2Device complexity
If only moving direction and moving distance prediction is performed without considering pre-stop moving range, then the determination process is simple, but the presentation for preventing collision before stop is insufficient
Solution Approach 1:
The system calculates the pre-stop moving range in advance based on current vehicle speed and braking characteristics. This preliminary calculation is then integrated with the obstruction prediction, enabling accurate collision prevention presentation without significantly increasing determination process complexity
Solution Approach 2:
The system introduces the pre-stop moving range as an additional parameter to the collision determination process. By incorporating this parameter that reflects the actual stopping distance, the system improves presentation accuracy for collision prevention while maintaining a structured and manageable determination process

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.
