Abstract
The disclosure relates to a control method for an automated guided forklift, and an automated guided forklift and a controller applying same. The method includes the following steps: determining an angle and a height of the body of the automated guided forklift; determining a height of a fork hole of the carrier; and adjusting an angle and vertical displacement of a fork of the automated guided forklift according to the height of the fork hole and the angle and the height of the body, so as to limit an included angle between the fork and the carrier within a first angle threshold range, and to limit a height difference between prongs of the fork and the fork hole within a first distance threshold range.

An automated guided forklift, comprising a processor, wherein in a process of picking and placing a carrier by the automated guided forklift, a body of the automated guided forklift is in an inclined state, the carrier is in a roughly horizontal state, and the processor is configured to execute a program instruction so as to implement the following steps:
- determining an angle and a height of the body of the automated guided forklift;
- determining a height of a fork hole of the carrier;
- and
- adjusting an angle and vertical displacement of a fork of the automated guided forklift according to the height of the fork hole and the angle and the height of the body, so as to limit an included angle between the fork and the carrier within a first angle threshold range, and to limit a height difference between prongs of the fork and the fork hole within a first distance threshold range.
