Abstract: A powertrain including a prime mover and an electronically controllable clutch. The powertrain structured selectably engages the clutch to provide power from the prime mover to drive one or more ground contacting wheels and to selectably disengage the clutch to decouple with one or more ground contacting wheels. The electronic control system operatively communicates with the prime mover and the electronically controllable clutch, and uses a predictive cruise control (PCC) controller and an idle coast management (ICM) controller, to control vehicle speed during concurrent operation of the PCC controller and the ICM controller.

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: A method includes receiving, by a controller, information indicative of a temperature of an aftertreatment system of the vehicle and an exhaust gas characteristic. The method includes comparing, by the controller, the temperature of the aftertreatment system to a temperature threshold, and comparing, by the controller, the exhaust gas characteristic to a characteristic threshold. The method includes, responsive to the comparisons, commanding, by the controller, an aftertreatment system heater to selectively engage or disengage to warm the aftertreatment system of the vehicle.

Abstract: Systems and apparatuses include one or more processing circuits including one or more memory devices coupled to one or more processors. The one or more memory devices are configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to: receive a parameter regarding operation of a first vehicle of a first platoon; compare the parameter to a first predetermined threshold; responsive to determining that the parameter satisfies the first predetermined threshold, determine an exit parameter for the first vehicle; and cause the first vehicle to exit the first platoon based on the exit parameter.

Abstract: A system and method for power management of hybrid electric vehicles is provided. In some implementations, a plug-in series hybrid electric vehicle may include an engine, a motor/generator (MG), a traction motor, an energy storage device, and a controller. The controller is coupled to the engine and the MG to control operation of the engine and the MG such that a state-of-charge (SOC) of the energy storage device tracks a dynamic reference SOC profile during a trip and an average engine power (AEP) is maintained above a threshold. In some instances, maintaining AEP above a threshold supports emission control of the vehicle.

Abstract: The enclosed disclosure relates to hybrid vehicles and systems with an engine, a drivetrain with a clutch and a transmission, an electric machine, and a controller. The controller receives lookahead information within a lookahead window and present state information of the hybrid vehicle. The controller determines a predicted coasting opportunity exceeding a predetermined threshold within the lookahead window and determines a cruise control reference speed, a power split between the engine and the electric machine, and a timing of enabling engine-off coasting during the coasting opportunity. The controller deactivates the engine and disengages the clutch at a start of the coasting opportunity when the engine-off coasting is enabled.
