The present invention relates to a method for controlling a torque generated by at least one electric motor (130) of an electric lift truck (100), the method comprises: detecting (210) a fulfilment of at least one criterion when the torque of the at least one electric motor (130) is in a first mode, the fulfilment of the at least one criterion indicating insufficient amount of the torque in to maintain a motion of the electric lift truck (100), triggering (220) an electrical drive (140) of the at least one electric motor (130) to generate a control signal to generate a torque being larger than the torque of the at least one electric motor (130) in the first mode to change the torque to an increased torque mode. Some aspects relate to a control unit (150), to a computer program product and to an electric lift truck (100).
