Systems and methods to update the calibration data of a control system includes a calibration system. The calibration system includes a first cloud connected application system structured to communicatively couple to a second cloud connected application system, determine, via at least one of the first cloud connected application system or the second cloud connected application system, a calibration update request corresponding to a control system, generate custom calibration data including preference data based on at least one of the calibration update request or the preference data, and provide the custom calibration data during at least one of an active engine state or an inactive engine state, wherein the custom calibration data is transmitted from the second memory portion to the first memory portion in response to the inactive engine state.

Updating electronic controller through telematics

One exemplary embodiment is a method of controlling a vehicle system including an engine, a transmission, and a control system in operative communication with and structured to control operation of the engine and the transmission. The method determines an operating point of the engine including an engine torque and an engine speed and evaluates a relationship between the operating point and a soft limit on engine torque. The method modifies the soft limit to permit operation outside a boundary of the un-modified soft limit. Modification of the soft limit is constrained by a non-adjustable limit. The operating point of the engine is adjusted to increase engine torque above the boundary of the un-modified soft limit. The method may mitigate a vehicle speed lug event and/or avoid a transmission shift event.

Powertrain controls including transient torque management with dynamic release compensation

Systems, methods and techniques for exhaust gas recirculation are provided. The system includes controlling the mixing of exhaust flow from at least one cylinder of an engine with air in an air intake system prior to combustion in response to an EGR fraction deviation condition. The exhaust flow from the at least one cylinder is accumulated prior to mixing and distributed into the intake air system in a controlled manner to mitigate or prevent the EGR flow from deviating from an expected EGR fraction.

Transient control of exhaust gas recirculation systems through mixer control valves

A method includes determining a first NOconversion efficiency (&#x3b7;) value and determining that a diesel exhaust fluid (DEF) level has increased a threshold amount. Further, the method includes determining a second NOconversion &#x3b7; value and comparing the first NOconversion &#x3b7; value and the second NOconversion &#x3b7; value, determining a NOconversion &#x3b7; change in response to comparing, and determining a DEF quality indicator in response to the NOconversion &#x3b7; change.
