Abstract: A method for controlling vehicle speed comprises selecting an engine speed profile for a vehicle. Road grade data is received and processed to determine a road grade for the vehicle. Vehicle speed data is received and processed to determine a vehicle speed for the vehicle. A cylinder deactivation mode for a valvetrain of a multi-cylinder engine of the vehicle is selected. The cylinder deactivation mode comprises deactivating one or more intake valve, exhaust valve, and fuel injection for one or more cylinder of the multi-cylinder engine. The selected cylinder deactivation mode provides a controlled deviation from the selected engine speed profile at the road grade and vehicle speed.

Abstract: A valvetrain for a type II engine comprises a valve bridge, a switching rocker arm, a center capsule, a first auxiliary rocker arm, and a first auxiliary capsule. The selectively switching rocker arm is configured to switch configurations to transfer a first valve actuation profile from a first overhead cam lobe to the valve bridge center point and to transfer a second valve actuation profile from a second overhead cam lobe to the center point. The center capsule is configured to switch between an active state and a lost motion state. The first auxiliary rocker arm is configured to transfer a first auxiliary valve actuation profile from a third overhead cam lobe to the valve bridge first valve mounting area. The valvetrain can further comprise a second auxiliary rocker arm and a second auxiliary capsule.

Abstract: A method for engine braking on a type III valvetrain diesel engine comprises, on a first downstroke of a reciprocating piston, deactivating a normal intake lift profile on a first intake valve to implement a deactivated intake profile. Before a first upstroke of the reciprocating piston completes, a late intake valve closing lift profile is actuating on a second intake valve and beginning an engine brake lift profile on a first exhaust valve. On a second downstroke of the reciprocating piston, the engine brake lift profile on the first exhaust valve is completing and a normal exhaust lift profile is deactivating on a second exhaust valve to implement a deactivated exhaust profile on the second exhaust valve. Before a second upstroke of the reciprocating piston completes, a second engine brake lift profile is beginning on the first exhaust valve.

Abstract: A transmission system selectively coupled to an engine crankshaft of an internal combustion engine arranged on a vehicle includes a transmission, an aftertreatment system, an accessory device and a controller. The aftertreatment system reduces emissions in an exhaust of the internal combustion engine. The accessory device is configured to provide power. The controller operates in an aftertreatment heat-up mode such that the aftertreatment system is heated up to an elevated temperature and emissions are thereby reduced based on the elevated temperature. The controller is configured to heat up the aftertreatment system to reach between one (1) and two (2) kilowatt hours (kWh) of enthalpy before two minutes at engine startup by (i) operating the internal combustion engine in cylinder deactivation mode (CDA); (ii) operating the internal combustion engine at an elevated idle speed; and (iii) operating the accessory device at a threshold power.

Abstract: A system includes a PTO device that selectively couples to a driveline of a vehicle at each of two driveline coupling positions, and a motor/generator electrically coupled to an electrical power storage system. The system further includes a shared load selectively powered by the driveline or the motor/generator. The PTO device further includes a coupling actuator that couples the shared load to the motor/generator in a first position, and couples the shared load to the driveline in a second position.

Abstract: A method for controlling a transmission of a vehicle during cylinder deactivation can comprise receiving and processing a zero or negative torque requirement for the vehicle. Receiving and processing vehicle speed data can be included to determine a vehicle speed for the vehicle. A cylinder deactivation mode can be implemented for a valvetrain of a multi-cylinder engine of the vehicle, wherein the cylinder deactivation mode comprises deactivating one or more intake valve, one or more exhaust valve, and fuel injection for one or more cylinder of the multi-cylinder engine. Selecting one of an in-gear mode and a neutral mode for a transmission of the vehicle can be included while implementing the cylinder deactivation mode and while maintaining the determined vehicle speed.
