20100115920 | Exhaust component having permanently associated life indicator - An exhaust component for use with a combustion engine is disclosed. The exhaust component may have a housing at least partially defining an inlet and an outlet, and a treatment device supported by the housing in communication with exhaust passing from the inlet to the outlet. The exhaust component may also have a life indicator permanently associated with at least one of the housing and the treatment device. | 05-13-2010 |
20130303321 | DRIVE SYSTEM HAVING A PLANETARY GEAR SET - A machine includes a power source, a transmission, and a drive system configured to transmit torque from the power source to the transmission. The drive system includes a planetary gear set, a variator coupled to the planetary gear set, and a storage device operably connected to the variator. The storage device is configured to receive energy from and provide energy to the variator. | 11-14-2013 |
20130303333 | CONTROLLING A DRIVE SYSTEM HAVING A PLANETARY GEAR SET - A method of controlling a drive system includes receiving a machine travel speed request, and determining an output speed of a variator, associated with the drive system, required to satisfy the travel speed request at a current power source speed. The method also includes determining that a storage device operably connected to the variator has an amount of stored energy sufficient to operate the variator at the variator output speed, and providing torque to a machine transmission with a machine power source and the variator. The variator is operated at the variator output speed using stored energy from the storage device to provide torque to the transmission. The torque provided to the transmission with the power source and the variator is sufficient to satisfy the travel speed request at the current power source speed. | 11-14-2013 |
20140052359 | System And Method For Controlling Torque Load Of Multiple Engines - A method of controlling torque load of multiple engines according to a torque distribution algorithm includes determining a combined torque output value responsive to actual torque outputs of first and second engines. A desired torque output for the first engine is determined responsive to a first desired contribution portion of the combined torque output value, and a desired torque output for the second engine is determined responsive to a second desired contribution portion of the combined torque output value. A torque error for each of the first and second engines is determined responsive to a difference between the desired torque output for a respective one of the first and second engines and the actual torque output from the respective engine. Operation of each of the first and second engines is controlled responsive to the respective torque error. | 02-20-2014 |
20140077599 | Multiple Hybrid Integration - A power platform for a motorized work device that includes hybrid power sources is disclosed. The hybrid power system may include a hydraulic power source that provides power and stores power, an electric power source that provides power and stores power and a kinetic power source that provides power and stores power. | 03-20-2014 |
20140077610 | SELECTING A HYBRID POWER SOURCE - A method of controlling power in a hybrid power system comprising a plurality of power sources is also disclosed. The state of charge of each power source may be determined where the power source stores and provides power. A current power score for each power source may be determined where the power score is a function of the current state of charge and state of efficiency. If there is power demand, power may be provided from the power source with the highest current power score. | 03-20-2014 |
20140080660 | USING AN INTEGRATED STARTER/GENERATOR TO REPLICATE IMPELLER CLUTCH FUNCTIONALITY - A method utilizing an integrated starter generator as a hybrid power source to an engine in a movable device is also disclosed. The impeller clutch activation decision may be based on load demand, more specifically, whether load demand for the engine is greater than the power from the engine at the current speed of the engine. | 03-20-2014 |
20140121868 | Prediction Control Strategy for Hybrid Machinery - A computing system may provide guidance to a vehicle with hybrid power systems on how to efficiently engage the hybrid systems and the primary power source on a given plan. As a result, additional efficiency may be obtained. | 05-01-2014 |
20140172252 | Grade and Payload Estimate-Based Transmission Gear Selection - A vehicle includes an automatic transmission and a set of sensor inputs providing values indicating a current operational status of the vehicle pertinent to controlling the automatic transmission. The set of sensor inputs include: engine speed, engine torque, current transmission gear; and vehicle speed. The vehicle includes a programmed processor configured to iteratively and co-dependently generate a vehicle mass parameter value and a grade of incline parameter value. The programmed processor, when generating the vehicle mass parameter value and the grade of incline parameter value, uses a set of parameters including: a propulsive force driving the vehicle; a set of forces acting on the vehicle resisting forward movement, and an observed rate of change of a speed of the vehicle. | 06-19-2014 |
