Benjamin Fernando Fernandez Guzmann has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11231718
    Abstract: An autonomous skid-steer machine includes a chassis, a plurality of ground engaging elements supporting the chassis on a ground surface and one or more computing devices for controlling movement of the machine. The one or more computing devices are configured to generate a control signal for controlling operation of at least some of the plurality of ground engaging elements, the control signal being generated according to a control algorithm incorporating tuning parameters, and to automatically determine the tuning parameters in real time during operation of the machine such that the control algorithm is always optimized for a current speed of the machine. The tuning parameters are found using the machine's current speed, a natural frequency value and a damping value.

  • Patent number: 11054828
    Abstract: A control system for an off-road vehicle is configured to provide automatic guidance for the vehicle. The control system is configured to apply an estimator to determine a plurality of system process parameters, determine a reference model based at least in part on user input, determine a plurality of control parameters using the process parameters and the reference model, determine a guidance input according to the control parameters, a setpoint of a desired output, and a previously measured output, and use the guidance input to automatically guide the vehicle. The estimator is configured to determine the plurality of system process parameters such that the control system automatically guides the vehicle so that the vehicle responds substantially in the same manner across different ground surface conditions, hitch forces and vehicle velocities.
