Vehicle Display Control Dynamic Image Mode Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display control systems for vehicles fail to effectively notify occupants of the vehicle's movement mode towards a target position while providing an easy-to-understand visualization of the surrounding situation, especially when the vehicle is moving towards a target position.
Innovation Solution
A display control device that includes an image data acquisition unit to capture images around the vehicle and a display processing unit to display a peripheral image, along with a real vehicle image indicating the current state and a virtual vehicle image indicating the future state, with the display mode of at least one of these images changing based on the remaining distance to the target position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional display control systems show only static vehicle images, then the display is simple and easy to understand, but the system cannot effectively notify occupants of the vehicle's movement mode towards a target position
Solution Approach 1:
The patent applies the dynamics principle by dynamically changing the display mode of vehicle images based on the remaining distance to the target position. The system transitions from static to dynamic display, where the first vehicle image and second vehicle image are shown in different modes (e.g., transparent vs. opaque, different positions) depending on whether the vehicle is close to or far from the target, thereby conveying movement mode information without overwhelming complexity
Solution Approach 2:
The patent uses preliminary action by displaying a second vehicle image that shows the future state of the vehicle before the movement actually occurs. This predictive display allows occupants to anticipate the vehicle's movement mode and future position, providing advance information about the vehicle's intended action towards the target position
2Loss of information
If the system displays detailed information about vehicle state and surrounding situation, then the occupant's awareness is enhanced, but the display becomes complex and harder to understand
Solution Approach 1:
The patent applies segmentation by dividing the vehicle image information into two distinct parts: a first vehicle image showing the current state and a second vehicle image showing the future state. This segmentation allows the system to present multiple pieces of information (current position, future position, movement mode) in a structured, organized manner that is easier to process and understand than a single complex display
Solution Approach 2:
The patent uses local quality by applying different display characteristics to different parts of the vehicle image information. The first vehicle image and second vehicle image are displayed with different properties (transparency, position, size) depending on the remaining distance to the target, allowing critical information to be emphasized while maintaining overall simplicity
3Loss of information
If the display shows static images without dynamic adjustment, then the display mode is simple, but the system cannot convey the vehicle's approach to the target position
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting display parameters (such as transparency, position, or size of vehicle images) based on the remaining distance to the target position. This allows the system to convey information about the vehicle's approach to the target using simple parameter adjustments rather than complex display mode switches or additional hardware

AI summary
A display control device includes: an image data acquisition unit configured to acquire image data as a result of imaging by an imaging unit that images a situation around a vehicle; and a display processing unit configured to display, on a display unit, a peripheral image indicating the situation around the vehicle generated based on the image data and also display, on the peripheral image, a first vehicle image indicating a current state of the vehicle and a second vehicle image indicating a future state of the vehicle when the vehicle moves toward a target position and to change a display mode of at least one of the first vehicle image and the second vehicle image according to a remaining distance to the target position of the vehicle.
