WIPO Patent Application WO/2021/218152

A1

A navigation control method for a track laying machine, a track laying machine, and a track laying machine system. The navigation control method for a track laying machine (1) comprises: obtaining real-time planar coordinates of the track laying machine (1), and obtaining, from a preset planned path, coordinates of two adjacent virtual coordinate points close to the real-time planar coordinates; obtaining, according to the coordinates of the two virtual coordinate points and the real-time planar coordinates, the deviation of the track laying machine (1) with respect to the preset planned path; and controlling, according to the deviation, the track laying machine (1) to operate. The method can improve the navigated operation precision of a track laying machine, and reduces errors of the track laying machine during track laying operation.
