Patent attributes
A joint orientation system is provided for a work vehicle having a chassis and an implement coupled to the chassis at a joint. The joint orientation system includes a first IMU positioned on a first side of the work vehicle relative to the joint and configured to collect a first IMU acceleration and a first IMU angular velocity and a second IMU positioned on a second side relative to the joint and configured to collect a second acceleration and a second angular velocity of the implement. A controller is configured to receive the first and second IMU accelerations and the first and second IMU angular velocities; determine a joint orientation correction based on IMU accelerations and IMU angular velocities; modify an estimate of joint orientation with the joint orientation correction to generate a current joint orientation; and output the current joint orientation for actuation of the implement.
