Vehicle Display Control Using Simulated Headlight Beam Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional preventive safety technologies in vehicles fail to provide simple and easy-to-understand prompt messages, affecting driving safety and convenience, especially for vulnerable road users.
Innovation Solution
A display control device and method that projects an information image representing a target recognition vehicle in different modes based on the intersection of traveling directions, using a first mode for non-intersecting directions and a second mode simulating a vehicle headlight beam for intersecting directions to enhance user understanding of location and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional display technology is used to provide safety information to the driver, then information can be transmitted, but the driver cannot quickly understand the information content, affecting driving safety
Solution Approach 1:
The patent uses different display modes with distinct visual characteristics (first mode and second mode) to represent different types of target vehicles. The second mode specifically simulates headlight beam patterns to intuitively convey directional information, enabling drivers to quickly comprehend spatial relationships and improve reaction time.
Solution Approach 2:
The patent projects the information image onto a screen member that is provided between the target recognition vehicle and the user, creating a layered display dimension. This allows the safety information to be superimposed on the driver's field of view without blocking the actual road scene, enabling simultaneous awareness of both the environment and the warning information.
2Loss of information
If detailed information about target vehicles is displayed, then comprehensive safety data is provided, but the display becomes complex and harder to understand quickly
Solution Approach 1:
The patent segments the display information into different modes based on the type of target vehicle detected. The first mode represents non-motorized vehicles, while the second mode represents motorized vehicles with simulated headlight beams. This segmentation allows the driver to quickly distinguish between different vehicle types and their associated risks without being overwhelmed by uniform detailed information.
Solution Approach 2:
The patent changes the display parameters (visual mode) based on the detected target vehicle characteristics. When a motorized vehicle is detected, the system switches to the second mode with headlight beam simulation, which provides directional information in an intuitively understandable format, balancing information completeness with comprehension ease.

AI summary
The disclosure provides a display control device and a display control method thereof. The display control device controls a display device to project an information image representing a target recognition vehicle in a first mode on a screen member. The screen member is provided between the target recognition vehicle and a user of the vehicle. When a traveling direction of the target recognition vehicle intersects with a traveling direction of the vehicle, the display control device controls the display device to project the information image in a second mode on the screen member. The information image in the second mode includes an image simulating a vehicle headlight beam of the target recognition vehicle.
