Vehicle Display Processing Apparatus for Safe Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems face challenges in allowing drivers to safely complete operations limited by drive enforcement while traveling, as they may be forced to continue incomplete tasks due to limited access to navigation screens during stops, especially on highways where stopping opportunities are rare.
Innovation Solution
A vehicle display processing apparatus that determines whether the vehicle is at a stop or traveling, and if traveling, transfers the operation screen from a center display to a head-up display, enabling the driver to continue operations safely by reducing the need for visual confirmation of the center display during travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drive enforcement limits operations while the vehicle is traveling, then driving safety is improved, but operation completeness deteriorates
Solution Approach 1:
The display system dynamically switches between two display devices based on vehicle motion state. When the vehicle is detected to be traveling, the operation screen is displayed on the head-up display (second display device) instead of the center display (first display device). This dynamic adaptation allows drivers to complete operations safely during travel while maintaining full operational capability when stopped, thereby resolving the contradiction between driving safety and operation completeness.
2Ease of operation
If the operation screen is displayed on the center display while traveling, then operation accessibility is improved, but driving distraction increases
Solution Approach 1:
The head-up display serves as an intermediary device that presents operation screens in the driver's forward field of view. By projecting the operation screen through the windshield or onto a transparent surface in front of the driver, the system allows drivers to access navigation and other vehicle functions without shifting their gaze to the center display, thus maintaining operation accessibility while eliminating driving distraction.
3Measurement precision
If the driver must stop the vehicle to complete operations, then operation accuracy is improved, but time efficiency deteriorates
Solution Approach 1:
The system prepares operation screens in advance and makes them available through the head-up display before the driver needs to stop the vehicle. By having the operation interface ready and accessible in the driver's field of view during travel, the driver can complete operations such as setting destinations or adjusting navigation without waiting for a stop, thereby maintaining operation accuracy while eliminating time loss.

AI summary
A vehicle display processing apparatus includes: a first determination portion that determines whether a vehicle is at a stop; a first display processing portion that displays on a first display device, an operation screen image, the first display device being provided between a driver seat and a front passenger seat; a second display processing portion that displays a screen image relating to the operation screen image, which is displayed on the first display device, on a second display device provided to a driver seat side; and a second determination portion that determines whether a running speed of the vehicle is equal to or greater than a predetermined speed. The second display device is provided by a head-up display. When the running speed of the vehicle is lower than the predetermined speed, the second display processing portion does not display the screen image on the second display device.
