    Abstract: A system includes a sensor array and a processing circuit. The processing circuit is operable to: store a policy; receive the sensor information from the sensor array; receive horizon information from a horizon system; input the sensor information and the horizon information into the policy; determine an output of the policy based on the input of the sensor information and the horizon information; control operation of a vehicle system according to the output; compare the sensor information received after controlling operation of the vehicle system according to the output relative to a reward or penalty condition; provide one of a reward signal or a penalty signal in response to the comparison; update the policy based on receipt of the reward signal or the penalty signal; and control the vehicle system using the updated policy to improve operation in view of the operating parameter.

    Abstract: Systems and apparatuses include a controller structured to: receive information indicative of an operating condition of a vehicle subsystem, receive information indicative of an external static condition, and receive information indicative of an external dynamic condition. The system is further configured to predict a fuel cut event based on at least one of the operating condition of the vehicle subsystem, the external static condition, and the external dynamic condition. Responsive to predicting a fuel cut event, the controller is structured to modulate at least one of a torque or a speed of the engine based on the operating condition of the vehicle subsystem and at least one of the information indicative of the external static condition and the external dynamic condition.

    Abstract: A system for control of an internal combustion system having subsystems, each with different response times. Subsystems may include a fuel system, an air handling system, and an aftertreatment system, each being operated in response to a set of reference values generated by a respective target determiner. Calibration of each subsystem may be performed independently. The fuel system is controlled at a first time constant. The air handling system is controlled on the order of a second time constant slower than the first time constant. The aftertreatment system is controlled on the order of a third time constant slower than the second time constant. A subsystem manager is optionally in operative communication with each target determiner to coordinate control. Generally, dynamic parameters from slower subsystems are treated as static parameters when determining reference values for controlling a faster subsystem.
