Abstract: Methods and systems for improving fuel economy and reducing emissions of a vehicle with an electric motor, an engine and an energy storage device are disclosed. The methods and systems involve obtaining lookahead information and current state information, wherein the lookahead information includes a predicted vehicle speed, and the current state information includes a current state of charge (SOC) for the energy storage device coupled to the electric motor; and determining, based on the lookahead information and the current state information, a target power split between the energy storage device and the engine.

Abstract: A cooling system for an electrified vehicle includes a first cooling loop for circulating coolant for cooling at least one of power electronics and a motor/generator of the vehicle. The first coolant loop includes a heat exchanger for exchanging heat with the coolant in the first cooling loop. A second cooling loop is provided for circulating coolant for cooling a battery of the vehicle. The second cooling loop includes a coolant chiller connected to a refrigeration system of the vehicle for exchanging heat in the coolant received from the battery with the refrigeration system of the vehicle.

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: Systems and methods for controlling a hybrid system. For example, a computer-implemented method includes determining a system temperature zone of the aftertreatment system as being in: a first temperature zone below a first temperature threshold, a second temperature zone from the first temperature threshold to a second temperature threshold, or a third temperature zone above the second temperature threshold; determining a power demand corresponding to the operation of the hybrid system as being in: a first power demand zone if the power demand is below a power threshold, or a second power demand zone if the power demand is equal to or greater than the power threshold; and determining a control strategy based at least in part on the determined system temperature zone and the determined power demand.

Abstract: Systems and methods for conditioning an aftertreatment system. For example, a computer-implemented method for conditioning an aftertreatment system of a hybrid system including an electric motor and a combustion engine includes: determining whether the aftertreatment system is in a first temperature zone below a first temperature threshold; determining whether a power demand corresponding to the operation of the hybrid system is in a first power demand zone below a power threshold; and if the aftertreatment system is determined to be in the first temperature zone and the power demand of the hybrid system is determined to be in the first power demand zone, setting the hybrid system to compressor mode to heat the aftertreatment system.
