    Abstract: A vehicle system includes an engine, a transmission, a differential, and a waste heat recovery (WHR) drive that converts thermal energy into mechanical and electrical energy. The WHR drive can include a WHR power unit structured to convert thermal energy into rotation of a WHR drive shaft. A motor/generator having a motor/generator shaft can selectively operate as a motor or a generator. A mechanical linkage is structured to selectively link an output shaft to one of the WHR drive shaft and the motor/generator drive shaft independently of the other of the WHR drive shaft and the motor/generator drive shaft. The output shaft is selectively coupled to one of the engine, the transmission, or the differential. The vehicle system may also include a traction motor to provide drive to the vehicle. The output shaft can be selectively coupled to the traction motor or the engine.

    Abstract: A system and method are disclosed for controlling the temperature of an aftertreatment system, the method including interpreting an aftertreatment indicating temperature, determining that an engine fueling requirement is zero, and disengaging the engine from a transmission in response to the aftertreatment indicating temperature falling below a first threshold value and in response to the engine fueling requirement being zero, where the engine and the transmission comprise a portion of a vehicle powertrain. Alternatively, the method may include interpreting an aftertreatment indicating temperature, determining that an engine fueling requirement is zero, and performing a reduced air flow operation through the engine in response to the aftertreatment indicating temperature falling below a first threshold value and in response to the engine fueling requirement being zero.
