Systems and methods for coordinated exhaust temperature control with electric heater and engine

A system, comprising:

• at least one controller structured to:
• determine whether an exhaust gas temperature is at or below a predefined threshold temperature;
• provide a first command to control a heater in response to the exhaust gas temperature being at or below the predefined threshold temperature;
• provide a second command to increase the exhaust gas temperature;
• and
• coordinate the first and second commands, wherein the first command is provided followed by the second command only if the predefined threshold temperature is not attained by the first command.

A method, comprising:

• determining that an exhaust gas temperature is at or below a predefined threshold temperature;
• and
• determining a sequence of commands, the sequence of commands including:
• providing a first command to control a heater responsive to determining that the exhaust gas temperature is at or below the predefined threshold temperature;
• and
• selectively providing a second command to increase the exhaust gas temperature.
