The core intention of the AutoMat project is to establish a novel and open ecosystem in the form of a cross-border Vehicle Big Data Marketplace that leverages currently unused information gathered from a large number of vehicles from various brands. The interface to the marketplace is derived from a brand-independent Common Vehicle Information Model (CVIM) that makes aggregated vehicle data accessible to cross-sectorial service providers. AutoMat intends to reduce the costs for realizing and providing services based on vehicle data.
