In order to make full use of the foundation provided by the smart ships and digital waterways, ship virtual aided driving is studied for the development of intelligent driving level and shipping.［Methods］Three different inland river routes were chose, in which ship virtual aided driving models were simulated based on the flow-ship interaction mechanism under the primary goal of security of ship sailing. In addition, the navigation rules and flow details of waterways were also considered.［Results］The simulation of ship sailing process in the typical inland river routes under specific current condition provides the corresponding virtual aided driving plan, in which
