Abstract
Disclosed is an automatic row-guiding method for maize combine harvester based on the situation of missing plants, comprising: S1, guiding calculation of missing plants according to a traveling speed of a harvester and output values of left and right detecting sensors; and S2, performing guiding calculation of missing plants if there is a situation of missing plant, obtaining a first target turning angle of an electric steering wheel; or obtaining a second target turning angle according to the output values of the left and right detecting sensors if there is no situation of missing plant, then adjusting the steering wheel in terms of controlling direction, and finally, realizing automatic row-guiding of the combine harvester.
