Abstract: A power system is disclosed. The power system may include one or more memories and a controller. The controller may determine an exhaust temperature of an engine associated with a continuously variable transmission or a hybrid transmission. The controller may determine a target increase to the exhaust temperature based on the exhaust temperature failing to satisfy a threshold. The controller may determine, based on a lookup table, a target increase to a torque output of the engine based on the target increase to the exhaust temperature. The controller may cause a parasitic torque of the engine to be increased based on the target increase to the torque output.

Abstract: A method for controlling a machine. The machine includes a swing system and a plurality of systems. The method comprises generating, by an inertial measurement unit, data pertaining to rotation of an upper carriage of the machine relative to a work surface, determining, by a controller, data pertaining to rotation of the upper carriage relative to an undercarriage of the machine based on the data generated by the inertial measurement unit. The method includes determining, by the controller, an amount of torque received by the swing system from a power source based on the data pertaining to the rotation of the upper carriage relative to the undercarriage, determining, by the controller, a total torque demand based on the first amount of torque and adjusting, by the controller, the total torque demand when the total torque demand exceeds a maximum torque capacity of the power source.

Abstract: A powertrain control system is disclosed for use with a mobile machine. The powertrain control system may have an engine, and a continuously variable transmission operatively coupled to the engine. The powertrain control system may also have an operator input device configured to generate a signal indicative of a desired speed of the engine, a feature selector usable by an operator to select activation of a powertrain control feature, and a controller in communication with the engine, the continuously variable transmission, the operator input device, and the feature selector. The controller may be configured to make a determination that the operator has selected activation of the powertrain control feature via the feature selector, lock a speed of the engine based on the determination and the signal, and lock a torque output of the continuously variable transmission based on the determination and the locked speed of the engine.

Abstract: A rollback prevention system is disclosed for use with a mobile machine having an engine and a transmission. The rollback prevention system may have an input device configured to receive an input indicative of a desired travel direction of the mobile machine, a sensor configured to generate a signal indicative of an actual travel direction of the mobile machine, and a controller in communication with the input device, the sensor, the engine, and the transmission. The controller may be configured to make a determination that the actual travel direction of the mobile machine is opposite the desired travel direction based on the signal, and determine a load on the transmission. The controller may also be configured to selectively increase a torque output of the transmission based on the determination only when the load on the transmission is less than a threshold value.
