The invention discloses a steering controller based on GMM, and a steering system of rear driving wheels of a forklift. The steering system is provided with the steering controller arranged on the rear driving wheels of the forklift; the steering controller is provided with a shaft sleeve and two sets of GMM mechanisms, wherein the two sets of GMM mechanisms are left-right symmetrically arranged in the shaft sleeve; each GMM mechanism comprises a GMM rod, a coil and a push-pull rod; each GMM rod is inserted in the corresponding coil; one end of each GMM rod is propped against the inner wall of the shaft sleeve, and the other end of each GMM rod is connected with the corresponding push-pull rod; an opening is formed in each of ends of the shaft sleeve, so that the push-pull rods can stretch out from the openings. The steering system disclosed by the invention can complete steering intervention without a driver; through the steering intervention of the rear driving wheels, the stability control for the forklift is realized, so that the purpose of automatically changing the steering angles of front wheels is achieved; the operation, the stability and the track keeping capability of the forklift are improved; the dangerous occasion, namely the rollover of the forklift, is avoided; besides, the steering controller based on GMM, which is disclosed by the invention, can overcome the defects that the existing hydraulic steering system for the forklift is complex in structure, a hydraulic oil is liable to leak, and the like.
