20100023605 | System and method for synchronizing configurations in a controller network - A method is disclosed for synchronizing configuration data. The method may include providing a controller network that includes a plurality of control modules and each control module may have registration information stored thereon. The method may include detecting a registration information change associated with a control module and receiving current configuration data from the control module, if the registration information change is detected. The method may also include creating new configuration data for each control module in the controller network based on the received current configuration data, and synchronizing the configuration of each control module with the created new configuration data. | 01-28-2010 |
20120253609 | Proportional control using state space based scheduling - A method for proportional state space based scheduling of gain within a machine includes generating a speed error value and when the speed error value is substantially nonzero producing an implement position difference value representing the amount by which an implement position differs from a position that would provide a desired machine speed. The method then converts the implement position difference value to a desired implement position command and differences the desired implement position command and a position signal indicative of the current implement position to produce an implement difference value. The implement difference value is used to generate one or more implement actuator signals | 10-04-2012 |
20120253631 | CVT control using state space based gain scheduling - An engine powered wheeled machine having improved engine over speed and under speed protection includes a parallel path transmission having a gear train with first and second transmission inputs and a transmission output, and including a hydraulic variator having a variator output driving the first transmission input, the hydraulic variator having a variator pump and a variator motor, the displacement of the variator pump being controlled by a variator actuator. The machine further includes an engine having an engine output driving the second transmission input and driving the variator pump and a controller for receiving one or more values indicative of one or more ranges of permissible engine speed, a value indicative of an actual engine speed, and a value indicative of the position of the variator actuator, with the controller being configured to control the position of the variator actuator based on state space gain mapping to maintain the engine speed within the one or more ranges of permissible engine speed. | 10-04-2012 |
20130260962 | ADAPTIVE POWER SOURCE CONTROL SYSTEM - A method of controlling a power source associated with a machine includes determining a difference between an underspeed setpoint associated with a peak power source torque and a first power source speed. The method also includes determining a torque distribution associated with the power source and at least one parasitic load receiving power from the power source. The torque distribution is based on the difference and respective torque priority values associated with the power source and the at least one parasitic load. The method further includes providing torque from the power source to the at least one parasitic load based on the torque distribution and modifying at least one of the respective torque priority values. Modifying at least one of the torque priority values reduces a difference between the underspeed set point and a second power source speed different than the first power source speed. | 10-03-2013 |
20130288856 | TORQUE CONTROL SYSTEM - A method of controlling a machine includes receiving a torque demand associated with at least one of a first parasitic load and a second parasitic load. At least the first parasitic load receives power from a power source of the machine via a transmission coupled to the power source. The method also includes providing torque from the power source to the at least one of the first and second parasitic loads in response to receiving the torque demand. In such a method wherein torque is provided to the at least one of the first and second parasitic loads based on a torque priority value associated with the at least one of the first and second parasitic loads. In addition, the torque priority value is adjustable by an operator of the machine during operation of the machine. | 10-31-2013 |
20130289836 | TRANSMISSION CONTROL SYSTEM - A method of controlling a transmission associated with a machine includes determining a torque demand associated with a parasitic load, the parasitic load receiving power from a power source of the machine via the transmission. The method also includes converting the torque demand into a corresponding torque request using a first neural network associated with a control system of the machine. The torque demand is an input of the first neural network and the torque request is an output of the first neural network. The method further includes directing the power source to provide torque to the transmission substantially equal to the torque request. | 10-31-2013 |
20140032057 | FEEDFORWARD CONTROL SYSTEM - A method of controlling a machine power source includes receiving a request indicative of desired machine implement movement. The desired movement will require a corresponding change in loading on a hydraulic pump. The method also includes determining a steady state torque required for the request, and determining a transient torque required for the request. The transient torque is based on a desired rate of implement movement associated with the request. The method further includes generating a power source fueling signal corresponding to a total torque required for the change in loading on the pump, and providing fuel to the power source based on the fueling signal prior to transmission of the change in loading on the pump to the power source. | 01-30-2014 |
