Claim 0:
1. A method for determining parallel lift feedforward control of a bucket of a work vehicle, comprising:
calculating, via a controller, a current stroke length of a bucket cylinder at a current moment based on a current bell crank plate angle and a current boom angle;
predicting, via the controller, a future boom angle after a certain number of steps;
calculating, via the controller, a required bell crank plate angle from a learned cutting edge angle and the future boom angle;
calculating, via the controller, a future stroke length of the bucket cylinder after the certain number of steps;
calculating, via the controller, an average speed command for bucket control based on the current stroke length and the future stroke length of the bucket cylinder; and
calculating, via the controller, a bucket cylinder control command based on the average speed command for bucket control.
