Method and device for calibrating a steering input device of an electric power steering of an industrial truck

摘要

EP1310419 NOVELTY - The steering wheel (30) has a reference position, which is assigned to the position of the floor conveyor wheels (12). A first sensor arrangement (34,36) detects the actual position of the steering wheel and a second sensor arrangement (22,26) detects the actual position of the wheels. The steering control determines, in an aligning phase for the detected actual positions of the steering wheel and the wheels, whether the steering wheel in its reference position leads to a predetermined position of the wheels during a predetermined transmission ratio between the steering wheel and the wheels. The steering control prevents the activation of the wheels during the aligning phase. After a successful determination, the steering control switches over into an operating phase, during which the movement of the steering wheel leads to the activation of the wheels with a predetermined transmission ratio.
