Abstract: Systems, apparatus, and methods are disclosed that include an internal combustion engine having a plurality of cylinders operable by a valve actuation mechanism that opens and closes the intake and exhaust valves during nominal engine operations. In response to engine operations indicating a cylinder deactivation condition, one or more the cylinders is selected for deactivation and operated by combusting an amount of fuel that is effective to limit air flow through the deactivated cylinder(s) so that the air flow and combusted fuel amount are less than during nominal cylinder operations.

Abstract: Apparatuses, systems, methods, and techniques relating to engine start/stop functionality are disclosed. Automatic engine start/stop controls can be disabled during engine operating conditions in which one or more combustion parameters indicate a lack of combustion stability in one or more cylinders of the engine. Engine start/stop controls are enabled when the one or more combustion parameters satisfy combustion parameter conditions indicating combustion stability in the one or more cylinders.

Abstract: A system, method, and apparatus includes management of cruise speed in anticipation of upcoming terrain changes. A cruise speed controller can be structured to predict a change in speed of vehicle in light of an upcoming terrain feature, and lead a change in reference speed to which the cruise speed controller is regulating vehicle speed to accommodate the upcoming terrain feature. In one embodiment a physics based model of the vehicle is used to predict a speed change. If predicted speed change exceeds a threshold, the cruise speed controller will initiate a change in speed to either speed up for an upcoming uphill terrain feature, or slow down for an upcoming downhill feature. In one form the distance in advance of the terrain feature as well as the velocity change profile (acceleration or deceleration) are determined by computation of a regression formula.

Abstract: An alternator voltage may be controlled based on a proportional gain scheduling in response to an engine load of an internal combustion engine and/or a state of charge (SOC) deviation for a battery based on a target SOC of the battery and an actual SOC of the battery. The alternator voltage may be a voltage less than a current battery voltage under high engine loads to enable the battery to power an accessory system and the alternator voltage may be a voltage greater than a voltage of the battery under low engine loads or engine loads less than high engine loads to enable the alternator to charge the battery.
