The invention discloses a space station large-scale flexible solar wing unfolding and folding and sun orientation comprehensive type driving control device, and aims at the unfolding and folding and sun orientation driving functions of a space station large-scale flexible solar wing. Driving circuits of a lifting mechanism, a box body unfolding and folding mechanism, a restraining and releasing mechanism, a stretching mechanism and a sun orientation driving mechanism which are used for achieving multi-step unfolding of the large flexible solar wing are integrated in the same comprehensive driving control device, and the high-integration-level design of aerospace products is achieved. The flexible working mode that the large flexible solar wing of the space station is fully automatically unfolded according to a program or independently unfolded and folded in a time-sharing and single-step mode is achieved; according to the technical scheme, high-reliability multi-type instruction interface design including 1553B bus communication and redundant OC hard wire instructions is achieved, under the high-priority OC hard wire instruction execution working condition, a drive control task can be completed in a minimum function circuit in a single machine in an isolated mode, and the high reliability requirement of the drive control device is met.
