The invention discloses a lift force cooperative high-speed train suspension semi-active comprehensive control method, which comprises a state early warning system, a vehicle GPS positioning device and a sensor, and the state early warning system, the vehicle GPS positioning device and the sensor are all carried on a high-speed train and are used for automatically identifying listed working conditions; under different working conditions of train operation, a better control algorithm is adopted, and real-time switching of the control algorithm is carried out according to different working conditions, so that the dynamic performance of the lift collaborative high-speed train is optimized. When a train runs under the working conditions of open line windless, open line crosswind, open line meeting and tunnel passing, a vertical switch type ceiling damping control algorithm, a transverse switch type hybrid damping control algorithm, a transverse virtual inertia damping control algorithm and a vertical virtual inertia damping control algorithm are adopted to conduct semi-active control on a speed reducer.
