Abstract: A cooling system is provided for an engine. The cooling system may have an air cooler configured to cool intake air being supplied to the engine. The cooling system may also have a sensor configured to generate a temperature signal indicative of a temperature of the intake air and a fan in proximity to the air cooler. The cooling system may further have a controller in communication with the sensor and the fan. The controller may be configured to cause the fan to operate at a speed that is a function of the temperature signal when the temperature of the intake air is above a threshold temperature. The controller may further be configured to selectively cause the fan to pulse when the temperature of the intake air drops below the threshold temperature.

Abstract: A powertrain control system is disclosed. The powertrain control system may have a power source and a CVT coupled to an output of the power source. The powertrain control system may further have a controller in communication with the power source and the CVT. The controller may have a map with a plurality of speed modes, and, for at least one of the plurality of speed modes, the controller may be configured to vary an actual power source speed based on at least one of a CVT output speed or a ground speed.

Abstract: A transmission system is disclosed as having a transmission configured to receive torque output from a power source and to drive a traction device, and an input device. The transmission system may also have a control module configured to reference a signal from the input device with a map to determine a corresponding speed of the power source, and to determine a margin between an actual and a maximum available torque output of the power source at a current speed. The control module may also be configured to determine a delay time threshold based on the margin, to selectively adjust a speed of the power source mapped to the maximum displaced position of the operator input device based on the margin, and to selectively adjust fueling of the power source at a current displacement position of the operator input device and operation of the transmission based on the signal and the map.

Abstract: A power system is disclosed as having a power source, a transmission configured to receive a torque output from the power source and to drive a traction device, and an operator input device. The power system may also have a controller configured to reference a signal from the operator input device with a map stored in memory to determine a corresponding speed of the power source, and to determine a margin between an actual and a maximum available torque output of the power source at a current speed. The controller may also be configured to selectively adjust a speed of the power source mapped to the maximum displaced position of the operator input device based on the margin, and to selectively adjust fueling of the power source at a current displacement position of the operator input device and operation of the transmission based on the signal and map.
