Actuator Control Mode Visualization in Vehicle Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face difficulty in understanding which vehicle actuators are in automatic or manual control mode, as existing systems represent automation levels with numerical values without clear differentiation between actuators.
Innovation Solution
A vehicle information display control device that uses images to represent control modes for each actuator, with a depth relationship between first (manual) and second (automatic) images to clearly indicate the control mode, ensuring the driver can easily identify which actuators are manually or automatically controlled.

Engineering Contradiction Analysis
1Loss of information
If numerical values are used to represent automation levels, then the system can indicate the degree of automation, but the driver cannot understand which specific actuators are in manual or automatic control mode
Solution Approach 1:
The display system segments the overall automation information into individual actuator-specific indicators. Each actuator (steering, accelerator, brake, shifter) has its own dedicated image or icon that independently shows its control mode, allowing the driver to understand the status of each actuator separately rather than receiving a single aggregated automation level number.
Solution Approach 2:
Visual images serve as intermediaries between the complex automated control system and the driver. Instead of directly displaying numerical automation levels or technical control mode data, the system uses intuitive images (such as icons representing each actuator) that mediate the information transfer, making it easier for the driver to comprehend which actuators are under automatic or manual control.
2Ease of operation
If the display shows detailed information about each actuator's control mode, then the driver can understand the control status, but the display becomes more complex and harder to interpret
Solution Approach 1:
The display applies different visual characteristics (such as color, brightness, or position) to different actuators based on their specific control mode. Each actuator's image can have localized visual properties that indicate its state, allowing the driver to quickly distinguish between manual and automatic control modes for each specific actuator without a uniform complex display structure.
Solution Approach 2:
The system adds a spatial dimension to the display by arranging actuator images in a specific spatial configuration (such as positioning images closer to or farther from the driver's viewpoint). This dimensional arrangement provides additional information about control modes without increasing the complexity of individual display elements, making the information easier to process visually.

AI summary
A vehicle information display control device includes: an automatic driving information obtaining unit that obtains automatic driving information including information indicating whether each of actuators of a vehicle is in a manual control mode or an automatic control mode; and a display controller that causes a display to display an image based on the automatic driving information. The display controller simultaneously displays a first image and a second image representing the manual control mode and the automatic control mode, respectively, of each of the actuators, and displays (i) the first image of an actuator in the manual control mode closer than the second image of the actuator in the manual control mode and (ii) the second image of an actuator in the automatic control mode closer than the first image of the actuator in the automatic control mode.
