PREDICTION OF DRIVE TORQUE IN HYDRAULIC WHEEL LOADER

This research presents method for the online estimation and prediction of drive forces in heavy duty vehicles. The estimation is based on the measured velocity and longitudinal dynamics. The same method can be applied for the prediction but the reference velocity is given as the input of the system instead of actual velocity. The prediction and estimation of drive forces are essential when optimizing the fuel consumption or emission. Especially, the control of the diesel engine requires information about loading torque for the prevent stalling of engine and guarantee rapid reaction of the machine.
