    Optimal control of wheel loaders in short loading cycles is studied in this paper. For modeling the wheel loader, the data from a validated diesel engine model is used to find a control oriented mean value engine model. The driveline is modeled as a switched system with three constant gear ratios (modes) of −60 for backwarding, 60 for forwarding, and zero for stopping. With these three modes

  • [PDF] Optimizing the trajectory of a wheel loader working

    A study into alternative trajectories for wheel loaders working in short loading cycles has been conducted, examining other patterns than the traditional Vor Y-cycle. Depending on workplace setup and target function of the optimisation other trajectories can indeed prove beneficial. The results of this study can be used in operator models for offline simulations as well as for operator

  • Achievement of Fuel Savings in Wheel Loader by Applying

    On the other hand, the wheel loader operation is highly repetitive, that means the general operating mode of wheel loaders can be predicted and modeled [3,13]. Considering these two aspects, this paper optimizes HMPSTs using some features of the typical operating mode, in order to find the optimal fuel saving potential solution for HMPSTs.
