Vehicle Control Device Authority Management via Parallel Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of automatic vehicle control systems, there is a need for appropriate authority management to ensure that only authorized service providers can use specific control information for vehicle control, preventing unauthorized access and processing delays.
Innovation Solution
A control device and method that acquire control information from an information processing device via wired or wireless communication, executing vehicle control processes while simultaneously performing authentication on usage authority, allowing the process to continue or suspend based on the authentication result, thereby ensuring proper authority management and preventing delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication process is performed before vehicle control process, then authority management is ensured, but processing delay occurs
Solution Approach 1:
The system performs preliminary authentication of usage authority before the vehicle control process begins. The control device acquires control information from an information processing device, authenticates the usage authority embedded in that information, and only then proceeds with vehicle control if authentication succeeds. This preliminary action ensures authority management is maintained while the parallel execution minimizes time loss.
Solution Approach 2:
The authentication process and vehicle control process are executed in parallel whenever possible. The control device initiates both processes simultaneously after acquiring control information, allowing the useful action of vehicle control to continue without waiting for authentication to complete, thereby reducing processing delay while maintaining security.
2Reliability
If usage authority is set in control information, then proper authority management is achieved, but device complexity increases
Solution Approach 1:
The control device is designed to handle multiple functions: acquiring control information from information processing devices, authenticating usage authority embedded in that information, and executing vehicle control processes. By integrating these functions into a single multi-functional device, the system achieves proper authority management without proportionally increasing overall system complexity.
Solution Approach 2:
The control information itself contains the usage authority information, allowing the control device to perform self-authentication without requiring additional external authentication systems. The control device extracts and validates the usage authority embedded in the control information it receives, enabling authority management through self-service mechanisms.

AI summary
A control device includes a communication unit configured to acquire control information on a vehicle from an information processing device in a wired or wireless communication, and a processing unit configured to execute a process of starting vehicle control based on the control information. The processing unit continues or suspends the process of starting vehicle control depending on a result of an authentication process on usage authority of the control information, and the authentication process is executed while the process of starting vehicle control is executed.
