HUD Passing Guidance for Lateral Positioning on Narrow Roads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems fail to provide adequate assistance for vehicles to smoothly pass each other on narrow roads by not anticipating the need for lateral position adjustment, leading to difficulties in maneuvering oncoming vehicles.
Innovation Solution
A display control device and program that utilize a head-up display (HUD) to overlap assistance images with the foreground, guiding drivers to adjust lateral position, and combine this with external environment images on a screen display to facilitate smooth passing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the driving assistance device displays the side camera image only when assistance is determined necessary, then the driver receives passing assistance information, but the driver cannot prepare in advance for lateral position adjustment
Solution Approach 1:
The system performs preliminary action by displaying the side camera image on the screen display device before the actual passing maneuver is needed. This allows the driver to view the blind spot area in advance, understand the spatial relationship with the oncoming vehicle, and prepare for lateral position adjustment before the critical passing moment arrives, thus resolving the contradiction between losing time and losing information.
2Ease of operation
If the system provides comprehensive passing assistance information, then the driver can maneuver smoothly, but the display complexity increases
Solution Approach 1:
The system applies segmentation by dividing the assistance information into two distinct display channels: the head-up display shows a simplified first assistance image with minimal overlay elements for immediate guidance, while the screen display device presents the comprehensive second assistance image with full external environment context. This segmentation allows comprehensive information provision without overwhelming the primary driving view, thus maintaining ease of operation while managing display complexity.

AI summary
A display control device or a non-transitory computer-readable storage medium storing a display control program grasps information of an oncoming vehicle that is a passing target on a narrow road, causes a head-up display to perform overlapping display of a first assistance image with a foreground of a subject vehicle, the first assistance image assisting a driver in lateral position adjustment, and displays, on a screen display device, an external environment image in which a second assistance image that assists passing overlaps with a capture image.
