This invention relates to the field of AGV control technology, and more particularly to an AGV safety control method based on ARM. This invention continuously collects the force values ​​at several load points on the load plane corresponding to different types of loads during AGV movement, and extracts specific behavioral features by combining historical movement characteristics, thereby constructing a set of historical specific behavioral features strongly correlated with the type of load. When a new control command is received, the relevant set of historical specific behavioral features is invoked to determine whether intervention is needed, and the control command is optimized, such as adjusting the moving speed or braking force, thereby improving the safety and operational reliability of the AGV under complex working conditions.
