Control Terminal App Access Management for Work Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to reliably prohibit the use of applications on a control terminal connected to a work vehicle with wireless communication, especially for vehicles with autonomous traveling functions, to ensure secure operation and prevent unauthorized access.
Innovation Solution
The control terminal includes a storage unit for app use permission/prohibition information associated with unique identification information of connected apparatuses, and an app use control unit that manages application access based on this information, ensuring that prohibited applications are not used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple applications are provided on the control terminal for controlling the apparatus, then the versatility and functionality are improved, but the risk of unauthorized access and security breaches increases
Solution Approach 1:
The patent segments the application set into multiple categories (first applications and second applications) with different access restrictions. The storage unit stores app use permission/prohibition information that divides applications into those permitted for use and those prohibited for use, allowing selective control over which applications can access the apparatus based on their security requirements.
Solution Approach 2:
The patent introduces an intermediary mechanism (the app use control unit with permission/prohibition information) that mediates between the user's request to use an application and the actual access to the apparatus. This intermediary checks the permission status of each application before allowing access, preventing unauthorized applications from compromising system security.
2Reliability
If application access is restricted based on permission/prohibition information, then security is improved, but the complexity of application management increases
Solution Approach 1:
The patent implements preliminary action by pre-storing the app use permission/prohibition information in the storage unit before runtime. The identification information of the apparatus is registered in advance with corresponding permission settings, so that when an application requests access, the system can quickly check the pre-configured permission status without complex real-time decision-making processes.
3Ease of operation
If the control terminal communicates wirelessly with the apparatus, then the ease of operation is improved, but the vulnerability to unauthorized connection increases
Solution Approach 1:
The patent implements feedback by having the app use control unit continuously monitor and check the permission status of each application attempting to communicate with the apparatus. When a wireless connection request is received, the system provides feedback by checking the stored permission information and either allowing or blocking the connection based on the pre-configured authorization status, preventing unauthorized wireless access.

AI summary
A control terminal 3 includes: a storage unit 94 for storing, in association with identification information of an apparatus 2, app use permitted/prohibited information that indicates whether the use of each of a plurality of applications by the apparatus 2 is permitted or prohibited; and an app use control unit 84 that receives the apparatus 2 identification information from the apparatus each time wireless communication connection with the apparatus 2 begins, and that controls the use of the plurality of applications on the basis of the app use permitted/prohibited information that is stored in the storage unit 94 in association with the received identification information.
