1. A method for delaying cylinder reactivation in a vehicle, comprising:
identifying, by a controller, a request to exit a cylinder deactivation state for an engine system of the vehicle, while the cylinder deactivation state is present;
determining, by the controller, if the request is due to a transient condition;
in response to the controller determining that the request is due to the transient condition, analyzing, by the controller, the transient condition and a condition of the vehicle based on data from a sensor, wherein the data from the sensor comprises a grade of a road being traversed by the vehicle or a size and shape of a curve in the road being traversed by the vehicle;
determining, by the controller, a first adjustment to the vehicle based on the analyzing by the controller the transient condition and the condition of the vehicle, the first adjustment configured to mitigate the transient condition;
implementing, by the controller, the first adjustment to the vehicle without exiting the cylinder deactivation state, the first adjustment comprising at least one gear shift event;
monitoring, by the controller, the transient condition to determine at least one change to the transient condition;
in response to the at least one change to the transient condition, determining, by the controller, a second adjustment to the vehicle, wherein the second adjustment is at least one of implementing a gear shift event, activating exhaust gas recirculation, or adjusting the position of a variable geometry turbocharger; and
implementing, by the controller, the second adjustment with the vehicle.
