Classification: CPC F  B | IPC B  F

Claim 7:
8. A system for delaying cylinder reactivation in a vehicle, comprising:
an engine system comprising a first cylinder and a second cylinder;
a controller coupled to the engine system, the controller configured to;
identify a request to exit a cylinder deactivation state for the engine system, while the cylinder deactivation state is present;
determine whether the request is due to a transient condition;
in response to the controller determining that the request is due to the transient condition, perform an analysis of 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;
determine a first adjustment to the vehicle based on the analysis, the first adjustment configured to mitigate the transient condition;
implement the first adjustment with the system without exiting the cylinder deactivation state, the first adjustment comprising at least one gear shift event;
monitor 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, determine 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
implement the second adjustment with the vehicle.
