IMPROVED DETERMINATION OF AN EXCAVATOR SWING BOOM ANGLE BASED ON AN ANGULAR VELOCITY RATIO
The present invention relates to a system for determining a swing boom angle of an excavator 1, wherein the excavator 1 comprises a vehicle frame 3 comprising a cabin 4, a swing boom 5 arranged on the vehicle frame 3 and configured to be rotated relative to the vehicle frame 3 about a first rotation axis 8 and a pneumatic or hydraulic cylinder 6. A first end of the pneumatic or hydraulic cylinder 6 is coupled to the vehicle frame 3 and a second end is coupled to the swing boom 5, wherein the cylinder 6 is configured to be rotated relative to the vehicle frame 3 about a second rotation axis 15 at the first end, wherein the cylinder 6 is configured to rotate the swing boom 5. The system comprises a first inertial measurement unit (IMU) 17, configured to be mounted on the swing boom 5 and to generate first IMU data, a second IMU 18 configured to be mounted on the cylinder 6 and to generate second IMU data and a processing unit. The processing unit is configured to receive the first and the second IMU data determine a first angular velocity of the swing boom 5 around the first rotation axis 8 based on the first IMU data and a second angular velocity of the cylinder 6 around the second rotation axis 15 based on the second IMU data when the cylinder 6 is actuated and determine the swing boom angle based on a ratio of the second angular velocity and the first angular velocity.
