Vehicle Display Control for Actuator Mode Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers have difficulty intuitively understanding which vehicle actuators are in automatic or manual control mode, as existing systems represent automation levels with numerical values without clear indication of control mode for each actuator.
Innovation Solution
A vehicle information display control device that obtains automatic driving information and displays images of manual driving devices corresponding to each actuator, with superimposed manual-operation or automatic-operation recalling images to indicate control mode, allowing drivers to visually distinguish between manual and automatic control.

Engineering Contradiction Analysis
1Loss of information
If automation levels are represented by numerical values (1, 2, 3), then the system can indicate the degree of automation, but the driver cannot intuitively understand which specific actuator is in manual or automatic control mode
Solution Approach 1:
The patent segments the overall automation information into individual actuator-level information. Instead of displaying a single numerical automation level, the system divides the control information by actuator (steering, accelerator, brake, shifter), showing the control mode for each specific component separately. This segmentation allows the driver to understand which specific actuator is in manual or automatic mode, resolving the ambiguity of numerical representations.
Solution Approach 2:
The patent uses visual copying of actuator images with superimposed icons to represent control modes. It creates visual copies of each actuator (steering wheel, accelerator pedal, brake pedal, shift lever) and overlays specific icons on them to indicate whether each is in manual or automatic control mode. This visual copying approach makes the control mode information intuitive and easily understandable, directly addressing the driver's difficulty in comprehending numerical automation levels.
2Loss of information
If the display shows detailed information about each actuator's control mode, then the driver can understand the control status, but the display complexity increases
Solution Approach 1:
The patent employs color changes and visual iconography to encode control mode information efficiently. Different colors and icon styles represent different control modes (manual vs. automatic), allowing the display to convey detailed actuator-level information without requiring complex text or numerical representations. This visual encoding reduces display complexity while maintaining information completeness.
Solution Approach 2:
The display system segments information presentation into modular actuator-specific units. Each actuator is represented by its own visual element with a superimposed control mode icon, allowing the system to display detailed control mode information for multiple actuators in a structured, non-overwhelming manner. This segmentation approach manages display complexity by organizing information into discrete, easily processable visual units.

AI summary
A vehicle information display control device includes: an automatic driving information obtaining unit obtaining automatic driving information including information indicating that each actuator of a vehicle is in a manual control mode or an automatic control mode; and a display controller causing a display to display an image based on the automatic driving information. The display controller causes the display to display: an image of a manual driving device corresponding to the actuator; a manual-operation recalling image that is superimposed on the image of the manual driving device corresponding to an actuator in the manual control mode and that recalls an operation performed by a person; and an automatic-operation recalling image that is superimposed on the image of the manual driving device corresponding to an actuator in the automatic control mode and that recalls an operation performed by a machine.
