Vehicle Meter Display Control for Driving Support Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems for braking/driving control information are difficult for drivers to recognize, especially in high driving load situations, as they rely on visual recognition of lamp lighting patterns, which can be distracting and decrease recognizability.
Innovation Solution
A display control method that superimposes a vehicle image on a background image on a meter panel display, changing the background image's display mode to notify the driver of active driving support controls, allowing for instantaneous visual recognition without focusing on the display content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lamp lighting patterns are used to display wheel control state information, then the driver can be notified of the controlled wheels, but the recognizability deteriorates in high driving load situations and the display becomes annoying
Solution Approach 1:
The patent uses color changes in the background image (specifically changing from a first color to a second color) to indicate the activation state of driving support controls. This color-based notification system provides reliable information transmission without requiring the driver to focus on specific display elements, thereby reducing attention burden while maintaining notification reliability.
Solution Approach 2:
The patent transitions from a one-dimensional lamp lighting notification system to a two-dimensional background image display system. By using the entire background image area and its color properties rather than discrete lamp positions, the system provides more intuitive spatial information that is easier to recognize peripherally, reducing the need for focused attention while maintaining reliable notification.
2Loss of information
If detailed lamp positioning information is displayed to show wheel control state, then the control information is provided, but the driver recognition becomes difficult under high driving load
Solution Approach 1:
The patent uses color changes in the background image to convey control activation information. The color transition from a first color to a second color provides clear, unambiguous information about driving support control activation without requiring detailed visual analysis, thereby maintaining information completeness while improving recognition accuracy under high load conditions.
Solution Approach 2:
The patent extracts the essential notification function from the detailed lamp positioning system and implements it through background image color changes. By separating the notification function from the detailed wheel position indication and implementing it through a different mechanism (background color rather than lamp patterns), the system maintains information delivery while improving recognizability.
3Ease of operation
If the background image display mode is changed to notify of driving support control activation, then the driver can grasp the change by peripheral vision, but the display complexity increases
Solution Approach 1:
The patent implements notification through color changes in the background image, which can be perceived by the driver's peripheral vision without requiring focused attention. This approach reduces visual effort for the driver while the underlying control system manages the color state transitions automatically, keeping the operational complexity low despite the enhanced notification capability.

AI summary
Information display is performed, in which recognizability of information regarding a driving support control is relatively good even in a situation where a driving load is relatively large, the information display not annoying a driver. A display controller displays a support state displaying image, which is an image having a configuration in which a vehicle image is superimposed on a mesh image as a mesh-like planar image, on a liquid crystal display device provided in a meter panel of a meter device. In addition, upon having determined that a driving support control implemented by a driving support device is operating, the display controller performs a display control to change a display mode of a mesh image portion of the support state displaying image, which is to be displayed on the liquid crystal display device, to a preset display mode.
