Execution state management method of steer-by-wire system

The invention relates to the technical field of steering systems, in particular to an execution state management method of a steer-by-wire system. An execution state management method of a steer-by-wire system is characterized in that the specific method comprises the following steps that S1, after a signal processing module processes signals of all ends, all kinds of effective signal signals are sent to a fault management module; s2, the fault management module judges a fault setting signal and then sends the fault setting signal to the state machine module; s3, controlling jumping of a state machine in the state machine module; and S4, when the state detection verification module passes the verification, outputting a normal verification state. Compared with the prior art, the execution state management method of the steer-by-wire system is provided, interaction of an upper steering system and a lower steering system is designed according to the characteristics of the steer-by-wire system, and a high-order a
