The invention discloses a complex working condition-oriented vehicle multi-system coordination torque control method, which belongs to the technical field of vehicle stability control, and specifically comprises the following steps of: 1) acquiring real-time state information in a vehicle driving process through a vehicle sensor; 2) analyzing a stable boundary and an ideal track of the vehicle in combination with various data information; (3) an integrated multi-system coordination controller is designed, ideal operation condition data serve as system input, and transverse and longitudinal force and yaw moment needed by operation of the vehicle in the ideal state are calculated; and 4) further distributing the kinetic parameters, and issuing the kinetic parameters to a specific lower system to realize final control. From the perspective of the whole, a multi-system coordination control scheme based on AFS, DYC and SFS is provided, a hierarchical management framework is adopted by a controller, and model predictive control and optimization control methods are combined. The control defect of a single system is overcome, and the movement stability of the vehicle under complex working conditions can be remarkably improved.
