On-Vehicle System Multi-Application Display Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems between mobile terminal devices and on-vehicle devices only display information from a single application software, failing to handle multiple applications simultaneously executed on the mobile terminal device.
Innovation Solution
An on-vehicle system that allocates and displays information from multiple application software on multiple display areas connected to the on-vehicle device, enabling simultaneous execution and visibility of multiple applications on the mobile terminal device and on-vehicle device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single application software information is displayed on the on-vehicle display, then the display is simple and easy to control, but multiple applications executed simultaneously cannot be displayed
Solution Approach 1:
The on-vehicle display is divided into multiple display areas, with each area dedicated to displaying information from a specific application software. This segmentation allows multiple applications to be displayed simultaneously without overwhelming the display system, as each application occupies a distinct segment of the display area.
Solution Approach 2:
The display control unit is designed to universally handle multiple application software types by allocating display areas based on application information received from the mobile terminal device. This multi-functional capability allows the same display system to accommodate various applications without requiring application-specific display hardware.
2Loss of information
If multiple display areas are allocated for multiple applications, then all applications become visible simultaneously, but the display allocation becomes more complex
Solution Approach 1:
The display control unit pre-establishes display area allocations for different application software based on information received from the mobile terminal device. By preparing the display allocation in advance before actual display needs arise, the system avoids complex real-time allocation decisions and ensures all application information is readily visible when needed.

AI summary
An on-vehicle system 100 according to an embodiment of the present invention causes a mobile terminal device 40 and an on-vehicle device 50 to work together, and allocates and displays two pieces of application software information about a widget from the mobile terminal device 40 on two display areas of gadget displays 61V and 62V connected to the on-vehicle device 50. Also, the allocation of the application software information is conducted via a touch panel 3 on the mobile terminal device 40 provided with a display device 6 for displaying a widget setting screen.
