Improved control system for an industrial truck

摘要

A method for controlling an industrial truck is disclosed, as well as a corresponding control system. The truck has at least one motor for driving a movable part of the truck and a sensor for measuring the actual motor speed and/or speed of the movable part in real time. The sensor transmits a real time speed signal representing the actual motor speed in real time to the controller, where the speed signal is compared with to predetermined data and/or to a speed control signal provided to the at least one motor. Based on the analysis, a secondary control data is generated for controlling the truck. The control method is usable in conjunction with a traction motor for the truck, whereby e.g. anti-spin and anti-brake lock functions could be implemented. The control method is also usable in conjunction with a motor/pump in a hydraulic system, whereby e.g. weight estimation and position determination functions could be implemented.
