Vehicle Hazard Display Modes for Blind Spot Target Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing preventive safety technologies in vehicles fail to provide drivers with location information of risk targets in their blind spots, making it difficult to detect potential collision hazards.
Innovation Solution
A display control system and method that uses a display control device to project location information of target recognition objects on a screen member, adapting between two modes based on the driver's visibility of the object, with a first mode for visible targets and a second mode for invisible targets, utilizing a vehicle location identification unit, map information, and captured images to ensure the driver is aware of all potential hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors and cameras are used to detect risk targets, then detection capability is improved, but blind spots remain where targets cannot be detected
Solution Approach 1:
The patent introduces an intermediary system consisting of multiple cameras positioned at different locations (front, rear, left, right) that capture images of areas not visible to the driver. These camera images are processed by a control unit that synthesizes them into a composite view, acting as a mediator to bridge the gap between what sensors can detect and what the driver can see directly.
Solution Approach 2:
The patent transitions from two-dimensional direct visual perception to a multi-dimensional information space by capturing images from multiple camera angles and projecting them onto a display surface. This allows the driver to access spatial information from blind spots that would otherwise be inaccessible, effectively adding dimensional coverage beyond the driver's direct line of sight.
2Loss of information
If the display shows location information of all targets, then driver awareness is improved, but display complexity increases
Solution Approach 1:
The patent segments the display information by spatial location, dividing the display area into multiple zones corresponding to different camera fields of view (front, rear, left, right). Each zone displays information from its corresponding camera, allowing the driver to systematically access information from different directions without overwhelming visual complexity.
Solution Approach 2:
The patent implements dynamic display behavior where the system adapts to driver needs by showing different information based on driving conditions. The control unit dynamically adjusts which target information is displayed and in what format, potentially highlighting only relevant targets or adjusting display intensity based on traffic conditions and driver behavior patterns.

AI summary
The disclosure provides a display control system and a display control method thereof. The display control device controls the display device to display the location information image on the screen member based on the current location of the vehicle, map information, a captured image, and location information of a target recognition object. When the user is able to see the target recognition object, the display control device controls the display device to display the location information image representing the location information of the target recognition object in the first mode on the screen member. When the user is not able to see the target recognition object, the display control device controls the display device to display the location information image representing the location information of the target recognition object in a second mode on the screen member.
