The invention relates to the technical field of navigation instruction analysis, and discloses a navigation instruction analysis method of a single-steering-wheel type transfer robot. The method comprises the steps of S1, receiving a signal, and receiving a signal instruction of departure of a navigation system; S2, predicting the position of a forklift; S3, setting a state variable, wherein the set state variable is represented by x; S4, establishing an observation equation, and and establishing a state observation equation of the single-steering-wheel forklift after the state variable is set; and S5, analyzing the state, calculating by using a Kalman filtering algorithm during state analysis, wherein the state analysis includes state prediction, position correction and noise estimation.According to the method, the navigation instruction is accurately analyzed into the execution speed and angle of the steering wheel, the track tracking performance of automatic driving of the forkliftis greatly improved, the safety and reliability of automatic driving of the forklift are guaranteed, and the operation efficiency of the forklift is improved.
