Vehicular Application Controller for Context-Aware Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicular systems, the execution of multiple applications can lead to unnecessary information being provided to users, distracting them and reducing concentration while driving, as well as overwhelming them with numerous icons for application selection.
Innovation Solution
A controller in the vehicular system specifies the purpose of use and selects suitable applications, inhibiting the execution of unsuitable applications to prevent wasteful execution of unnecessary information and simplify icon selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple applications are made executable in the vehicular system, then various pieces of information can be provided to the user, but unnecessary information is provided to the user which makes the user uncomfortable and lowers concentration on driving
Solution Approach 1:
The system dynamically changes the execution state of applications based on the detected purpose of use. The controller selectively executes or inhibits applications according to whether they match the current purpose, thereby adapting the system behavior to different driving scenarios and avoiding provision of unnecessary information that would distract the user
Solution Approach 2:
The system extracts and executes only the necessary applications related to the current purpose of use, while inhibiting execution of unrelated applications. This selective execution approach separates useful information from unnecessary information, ensuring that only relevant applications run based on the detected driving purpose
2Adaptability or versatility
If many applications are made executable, then various functions are available, but many icons must be displayed on the screen which takes much time for the user to find the desired application
Solution Approach 1:
The system extracts and displays only the icons corresponding to applications that are necessary for the current purpose of use. By filtering out unnecessary application icons based on the detected purpose, the system reduces the number of displayed icons, allowing users to quickly locate and select desired applications without being overwhelmed by irrelevant options
Solution Approach 2:
The display of application icons is dynamically adjusted based on the detected purpose of use. The system changes which icons are displayed on the screen according to the current driving context, ensuring that only relevant applications are visible and accessible, thereby reducing user search time while maintaining full functionality when needed

AI summary
A use specifying unit specifies a “purpose of use” of a vehicle based on a running-data table. An application selection unit selects one or more information-related applications which are suitable for the “purpose of use”, from a plurality of information-related applications. Then, an execution inhibition unit inhibits execution of information-related applications which are not selected to be suitable for the specified purpose of the vehicle. As a result, it is possible to prevent information-related applications which are unnecessary for the “purpose of use” of the vehicle from being executed wastefully.
