Abstract

A vehicle-based complex event processing (CEP) engine executes on at least one hardware computer processor in a first vehicle. The CEP engine receives a first input stream onto which vehicle information related to the first vehicle is published, and applies one or more queries to the first input stream to assess if a vehicle-related event has occurred. If it is determined that the vehicle-related event has occurred, the CEP engine publishes an indication of occurrence of the vehicle-related event on an output stream of the vehicle-based CEP engine, and transmits the indication of occurrence of the vehicle-related event from the first vehicle.
