Abstract
Industrial truck, in particular a lift truck, with a drive axle with drive wheels and a drive motor, a steering axle with two steerable wheels, a target value sensor that is connected to a steering wheel, a steering motor, a steering device which is in effective connection with a steering tie rod, a position transducer magnet whose position is recorded by two magnetic resonance sensors that are arranged in parallel, where the position transducer magnet and the resonance sensors are moved relative to each other during a steering movement of the steering device, and where the magnetic resonance sensors generate counter directional analog signals for the actual value of the steering angle of the steerable wheels, a steering control, connected to the target value sensor, the steering motor, and the magnetic resonance sensors, which evaluates the signals received from the target value sensor and the magnetic resonance sensors, and controls the vehicle steering angle to the target steering angle, where the signals of the magnetic resonance sensors are evaluated by the steering control for the recognition of malfunction of one of the magnetic resonance sensors.
