Abstract: One embodiment is a method of operating an electronic control system (ECS) to control an engine to propel a vehicle. The method comprises receiving a throttle command, determining an operation to increase engine cycle efficiency by reducing engine torque below a magnitude corresponding to the throttle command and below a torque curve limit over a first vehicle operation segment and permitting an increase in engine torque above the torque curve limit over a second vehicle operation segment, controlling the engine to output torque below the magnitude corresponding to the throttle command and below the torque curve limit over the first vehicle operation segment, and controlling the engine to output torque above the torque curve limit over the second vehicle operation segment in response to a second received throttle command and constrained by an extended limit on operation of the engine above the torque curve limit.

Abstract: A method, an optimization controller, and combustion engine are disclosed. The method includes determining, by an optimization controller, values of a performance parameter of a target vehicle using characteristics of at least two platoons travelling on a roadway, each of the values corresponding to a platoon of the at least two platoons; selecting, by the optimization controller, one of the at least two platoons based on a comparison of the values of the performance parameter, and coordinating, by the optimization controller, for the target vehicle to join the selected of the at least two platoons.

Abstract: A system for a vehicle includes a powertrain system including an engine, a transmission, a drive shaft, and a final drive. The system also includes a controller communicably coupled to the powertrain system. The controller is structured to: receive vehicle operation data during operation of a vehicle; receive route data for a route of the vehicle, wherein the route data is received in advance of the vehicle traveling the route; determine a cylinder deactivation event has occurred based on the vehicle operation data; determine an adjustment to a shift schedule for the transmission based on at least one of the cylinder deactivation event and the route data; and provide a command to implement the adjustment with the transmission.

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: 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.
