Remote Control Validation Logic for Secure Vehicle Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for vehicles lack the ability to validate and invalidate control operations securely, leading to potential improper implementations.
Innovation Solution
A remote control system with a command accepting unit and a controller that switches between valid and invalid states based on predetermined permission conditions, using communication units to verify and manage the switching process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If switching from invalidation to validation of remote control is unconditionally possible, then convenience for user is improved, but remote control may be implemented in improper situation
Solution Approach 1:
The system performs preliminary authentication checks (device authentication, person authentication, location authentication) before allowing validation of remote control. The command accepting unit checks whether the moving object is within a predetermined distance from the controller before switching from invalidation to validation state, preventing improper remote control activation.
Solution Approach 2:
The system provides feedback to the user about the authentication status and remote control validity. The judging unit determines whether authentication is successful and controls the command accepting unit accordingly, creating a feedback loop that ensures only properly authenticated operations can validate remote control.
2Reliability
If authentication checks are performed before validating remote control, then safety is improved, but operation complexity increases
Solution Approach 1:
The authentication system is segmented into three independent modules: device authentication (checking if the controller is a predetermined device), person authentication (checking if the operator is a predetermined person), and location authentication (checking if the moving object is within predetermined distance). This segmentation makes the complex authentication process more manageable and maintainable.
Solution Approach 2:
The command accepting unit serves multiple functions: it accepts remote control commands when in validation state, performs authentication checks, and switches between valid and invalid states. This multi-functionality reduces the need for separate dedicated components for each function.

AI summary
A remote control system includes a moving object including command accepting and first communication units. The command accepting unit is switchable between valid and invalid states. The valid state accepts a remote control command supplied from outside the moving object. The invalid state rejects the remote control command. The first communication unit transmits at least one information of first and second information. The first information indicates a sign that the operating state will switch to the valid state. The second information indicates that the operating state has switched to the valid state. A controller includes second communication and judging units. The second communication unit receives the at least one information. The judging unit permits switching of the operating state to the valid state when the judging unit judges that the second communication unit has received the at least one information and a predetermined permission condition is satisfied.
