Method for operating a mobile working machine and mobile working machine
Mobile machine 100 has a manipulator arm 110 mounted movably on a component 120 such as the body of the excavator 100 or a loading crane of a lorry. The position of the manipulator arm 110 relative to the body 120 is determined using at least one sensor 111, 112, 113, 114 mounted on the manipulator, such as displacement sensors, angle sensors, inertial sensors, rotation rate sensors and acceleration sensors. Rotation D of the body 120 about a vertical axis H of the mobile working machine 100 is detected using a rotation rate sensor 121. Over-all position of the manipulator arm 110 is determined using manipulator arm 110 position relative to the body 120 and rotational position of body 120 about the vertical axis H. The rotation position D of the body 120 is redundantly detected using a redundant camera 125 such as the vehicles rear-view manoeuvring camera 125. This uses image analysis to confirm position relative to external elements such as comparison of ground features. Alternatively, two or more cameras (Fig 4: 126, 127) mounted under body 120 can analyse relative position of excavator substructure 130 or wheels. Redundant image is used to compensate for vibration or noise reduction.
