Claim 19:
20. A system having exhaust gas emissions control, comprising:
an internal combustion engine configured to produce an exhaust gas having an exhaust emissions portion;
an exhaust gas aftertreatment apparatus configured to treat the exhaust gas to lower an amount of the exhaust emissions portion; and
a controller configured to:
set a target emissions value, for an emissions average value of the exhaust emissions portion, to achieve in relation to a period of time at a discharge from the exhaust gas aftertreatment apparatus; and
calculate an emissions reference value at a plurality of times during the period of time, wherein the emissions reference value is at least based on an already emitted amount of the exhaust emissions portion and the target emissions value during the period of time, wherein the emissions reference value is an emissions setpoint value selected to achieve the target emissions value by an end of the period of time, wherein the emissions reference value varies during the period of time, and the period of time occurs during a transient operating mode of the internal combustion engine.
