In-Vehicle Road Display for Target Object Crossing Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle display technologies do not effectively convey the possibility of a target object crossing a road, lacking clarity in display content regarding the object's actual position and direction relative to the vehicle.
Innovation Solution
An information processing device that displays a target object image on an in-vehicle display at a position reflecting its actual position in a road image, considering the object's expected crossing and orientation, and erases the image when the object is no longer expected to cross the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If target object information is displayed on the in-vehicle display, then the occupant can grasp the target object, but the display content does not clearly indicate the possibility of the target object crossing the road
Solution Approach 1:
The patent uses color changes in the target object image to indicate the possibility of crossing the road. When the target object is detected to have a high possibility of crossing, the image color changes to a predetermined color (e.g., red or orange), providing immediate visual information about the crossing risk without adding complex display elements.
Solution Approach 2:
The patent adds a new dimension to the display by showing the target object image at its actual position on the road rather than just on the HUD. This dimensional change from virtual overlay to actual road position representation provides clearer spatial context about the target object's location and crossing possibility.
2Measurement precision
If the target object image is displayed at the position reflecting actual position, then the occupant can grasp the actual position and direction, but the display may show unnecessary information when the object is no longer a threat
Solution Approach 1:
The patent implements dynamic display control where the target object image is automatically erased when the object is no longer expected to cross the road. This dynamic adjustment ensures that the display shows information only when relevant, maintaining position accuracy when needed while avoiding unnecessary information display when the threat has passed.
Solution Approach 2:
The system continuously monitors the target object's movement and crossing possibility, providing feedback that triggers erasure of the image when the crossing possibility ceases. This feedback mechanism ensures that the displayed information accurately reflects the current state of the target object's threat level.

AI summary
The information processing device includes a target unit. When a target object existing in a traveling direction of a vehicle traveling on a road is detected by a detection unit, and it is assumed that a positional relationship between the vehicle and the target object is in a predetermined state, and the target object crosses the road, the control unit displays a target object image showing the target object at a position reflecting the actual position of the target object in the road image showing the road displayed on the display unit in the vehicle.
