The invention discloses a method, a system and equipment for generating a recommended driving curve of a virtual marshalling train, and relates to the technical field of rail transit signal control, the method comprises the following steps: constructing a kinetic equation of the virtual marshalling train; constructing a first optimization function, a second optimization function, a third optimization function and a fourth optimization function corresponding to an outbound traction stage, an inter-station cruise stage, an interval speed regulation stage and an inbound parking stage based on a kinetic equation according to the operation stages of different virtual marshalling trains in combination with urban rail operation characteristics; and solving each optimization function to obtain the control input quantity of each train unit in each operation stage in the virtual marshalling train. According to the method, the problem of asynchronous operation under an existing virtual marshalling train operation control framework can be solved, the condition that emergency braking is easy to trigger when entering and exiting a station is improved, the station entering and exiting efficiency is improved, and the station dwell time difference of the virtual marshalling train is reduced.
