Vehicle Display Control Device Periodic Connection Image Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience discomfort due to prolonged waiting times when connecting a mobile terminal to a vehicle display system, as they cannot visually track the connection process, leading to increased focus on the display and potential distraction while driving.
Innovation Solution
A vehicle display control device that includes a reception unit for mobile terminal screen information, a display control unit, and a timing determination unit to display a connection-processing image only after a predetermined time, reducing the perceived waiting time and minimizing driver distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a during-connection-processing image is displayed continuously from the start of connection processing until screen information is displayed, then users can grasp the connection status, but the waiting time feels long and may distract drivers
Solution Approach 1:
The during-connection-processing image is displayed periodically rather than continuously. Specifically, the image is updated at predetermined intervals (e.g., every 5 seconds) during the connection processing period, rather than being displayed without interruption from the start of processing. This periodic display reduces the overall display duration while still providing users with connection status information at regular intervals, thereby shortening the perceived waiting time without completely eliminating status feedback.
2Loss of information
If a during-connection-processing image is displayed continuously, then users can know the connection is being processed, but users may gaze at the display which hinders driving
Solution Approach 1:
The connection processing image is displayed periodically at predetermined intervals rather than continuously, creating natural breaks in the display. These intervals reduce the cumulative time the display shows connection information, thereby reducing the likelihood that drivers will continuously gaze at the display during connection processing, while still providing sufficient status updates to keep users informed.
3Object-affected harmful factors
If no during-connection-processing image is displayed, then driver distraction is minimized, but users cannot grasp the connection situation
Solution Approach 1:
Instead of no display or continuous display, the system employs periodic display of the during-connection-processing image at predetermined intervals. This provides users with connection status information at regular intervals, ensuring they are kept informed about the connection process while minimizing overall display time and reducing driver distraction compared to continuous display.

AI summary
A vehicle display control device includes a timing determination unit that determines timing when it is authenticated that the mobile terminal is an object that can provide the mobile screen information after the start of processing of connection between an HCU and the mobile terminal. A display control unit displays a during-connection-processing image indicating that connection with the mobile terminal is being processed, on the display device after the timing is determined by the timing determination unit until the mobile screen information becomes possible to be displayed on the display device. The display control unit does not display the during-connection-processing image on the display device after the connection processing is started until the timing is determined by the timing determination unit.
