Dual Communication Device Authentication for Agricultural Vehicle Control

The patent separates authentication functions from control functions by assigning them to different communication devices. The first communication device exclusively handles authentication of the work machine, while the second communication device handles control operations. This functional separation ensures that authentication security is independently validated before control permissions are granted, preventing invalid work machines from controlling the traveling vehicle while maintaining clear system architecture.

The authentication process is performed as a preliminary action before control operations begin. The first communication device authenticates the work machine in advance, and only after successful authentication does the second communication device permit control operations. This preliminary validation ensures that security checks are completed before any control functions are activated, enhancing system reliability.

The patent divides controller functions into two separate communication devices with specialized roles. The first communication device handles authentication tasks while the second handles control operations. This segmentation allows each device to be optimized for its specific function using more cost-effective hardware, eliminating the need to purchase and deploy expensive high-performance controllers that would be required if a single device had to handle all functions simultaneously.

The patent creates two separate communication devices that replicate necessary communication capabilities for their respective functions. Rather than requiring one powerful controller to handle all tasks, the system uses two simpler devices, each with copied essential communication functionalities tailored to their specific roles, thereby reducing overall system cost while maintaining full functionality.
