Vehicle Display Control With Reachable Zones and Input Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle display systems lack appropriate operation controls that ensure safe and efficient use by drivers, particularly when large touch panel displays are used, as it may not be suitable for drivers to operate icons far away, potentially distracting them from driving.
Innovation Solution
A control device that divides the screen into areas, assigning priority devices for input operations based on the driver's reachability, suppressing inputs from non-priority devices, and managing operations between in-vehicle and external devices to prevent conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large touch panel display is used to provide comprehensive information and controls, then the display area and information capacity are improved, but the ease of operation deteriorates because icons and controls far from the driver are difficult to operate
Solution Approach 1:
The display screen is divided into multiple operational areas, with each area assigned to a specific device (in-vehicle display device or external device). This segmentation allows the driver to interact with nearby areas using the in-vehicle display while passengers can use external devices for distant areas, resolving the contradiction between large display area and ease of operation.
Solution Approach 2:
Different areas of the display are assigned different operational priorities based on their location relative to the driver. Areas closer to the driver are prioritized for in-vehicle display operations, while distant areas are prioritized for external device operations. This local differentiation ensures that each area is optimized for its intended user, improving overall operability while maintaining the large display area.
2Adaptability or versatility
If the entire screen is made operable to maximize functionality, then the versatility is improved, but the safety deteriorates because driver distraction increases when operating distant icons
Solution Approach 1:
The screen is segmented into operational zones with different safety priorities. The system identifies which areas should be operable through the in-vehicle display versus external devices, allowing full functionality while preventing driver distraction by restricting operation of distant areas to external devices only.
Solution Approach 2:
External devices serve as intermediaries for operations in distant areas of the display. Instead of requiring the driver to directly interact with distant icons on the in-vehicle display, the system uses external devices (such as mobile terminals) as mediators to handle operations in those areas, thereby maintaining safety while preserving versatility.
3Adaptability or versatility
If multiple devices can operate the entire screen simultaneously to maximize accessibility, then the versatility is improved, but the device complexity and conflict management increase
Solution Approach 1:
The screen is divided into operational areas, with each area assigned to a specific device. This segmentation simplifies multi-device operation by clearly defining which device should handle which area, eliminating the need for complex conflict resolution systems while maintaining broad multi-device accessibility.
Solution Approach 2:
Different operational priorities are assigned to different areas of the display based on their location and intended users. This local differentiation simplifies the overall operation management by creating clear, location-based rules for device interaction, reducing complexity while enhancing versatility.

AI summary
A control device that generates a screen displayed on a display device in a vehicle and a screen corresponding to the screen of the display device to an external device, wherein the control device includes: a selection unit for selecting the display device or the external device; a setting unit for setting an area for executing processing based on an operation input to the selected device, and for suppressing processing based on an operation input to a device other than the device selected by the selection unit; a processing unit for generating a screen based on operations associated with each area in the screen that are received by devices selected by the selection unit; and a display control unit for displaying the screen generated by the processing unit on the display device and providing a screen corresponding to the screen of the display device to the external device.
