    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.

    摘要: An industrial fork lift truck comprising an electric motor (3), a motor controller (2) for controlling the electric motor (3) and a truck computer (1) for controlling the motor controller (2), said truck computer (1) comprising a detection system (5) for detecting spinning and/or locking of the drive wheel of the truck characterized in that the detection system (5) is arranged to receive a signal corresponding to the momentary torque current of the motor (3); and further comprising:
    -a calculation unit (12) for calculating the theoretical torque current of the motor (3);
    -a comparison unit (13) for comparing the theoretical torque current of the motor (3) and the momentary torque current of the motor (3), wherein the truck computer is arranged to reduce the acceleration or the deceleration of the truck if there is a difference between the theoretical torque current of the motor (3) and the momentary torque current of the motor (3).
