Vehicle Interaction Engine Mapping for Flexible Content Calling

The patent introduces an interaction engine as an intermediary component that manages the binding relations between content providers and exhibitors. This engine maintains a mapping table that stores the correspondence relationships, allowing devices to query and establish bindings without modifying their own software. The interaction engine acts as a mediator that handles content registration, querying, and distribution, thereby resolving the technical contradiction by eliminating the need for widespread software modifications while maintaining reliable binding relations.

The patent implements a universal interaction engine that serves multiple devices and content types simultaneously. This engine provides multi-functional capabilities including content registration, binding relation management, querying by content ID, and distribution to multiple exhibitors. By creating a single universal system that handles diverse interaction content (vehicle state information, prompt information, third-party application information) across multiple devices, the patent improves content sharing capability while eliminating the need for device-specific software modifications.

The patent segments the interaction system into distinct functional components: content providers, an interaction engine, and exhibitors. The binding relations are segmented and stored in a mapping table within the interaction engine rather than being hard-coded in each device. This segmentation allows the system to maintain stable content management through the engine's centralized control while enabling flexible interaction mode changes by simply updating the mapping relations in the engine without modifying individual device software.
