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 connected vehicles. The interface to the marketplace forms one single point of data access for service providers and intends to supersede proprietary vehicle data interfaces. AutoMat develops and leverages the novel Common Vehicle Information Model (CVIM) data format, which harmonizes information and provides generic and brand-independent datasets.
