Work Vehicle Screen Transition Control for Reliable Screen Identification

The patent divides the screen management system into distinct functional modules: a screen identifier manager that assigns unique identifiers to each screen, a screen manager that tracks screen transitions, and a display instruction generator that processes operations. This segmentation allows each module to specialize in one aspect of screen management, ensuring reliable screen identification even when multiple screens are displayed simultaneously across different operation modes.

The patent implements a feedback mechanism where the screen manager continuously monitors the current screen state and provides this information to the display instruction generator. When an operator interacts with the display, the system uses the stored screen identifier to determine the current context and generate appropriate display instructions, ensuring that operations are performed on the intended screen. This feedback loop prevents unintended actions by maintaining awareness of the current screen state throughout the interaction sequence.

The patent implements a universal screen management architecture where the screen identifier manager, screen manager, and display instruction generator work together to handle all screen operations regardless of the specific screen type or operation mode. This multi-functional approach allows the same control mechanisms to manage simple information displays, complex hierarchical screens, and transitions between different operation modes, reducing overall system complexity despite the diverse information organization requirements.
