Autonomous Forklift Truck Control System and Methods for Driving a Forklift Truck

摘要

The invention relates to a system for controlling a forklift truck, the system comprising: human control means for generating manual driving signals for vehicle actuators, the means comprising a hydraulic steering unit; A control module (1) comprising an automatic control sub-module for generating autonomous driving signals intended for one or more vehicle actuators, according to the control signals; A switching module 2 designed to select one or more manual driving signals and / or one or more autonomous driving signals; An electrohydraulic valve which allows the driving signal from the automatic control module to be converted into a signal for the hydraulic steering unit, the system according to the speed threshold of the proportional-integral controller, the two-position controller, and the forklift truck And an electrohydraulic valve servo-control system comprising means for activating either a proportional-integral controller or a two-position controller.
