Abstract: A vehicle includes at least one electric motor configured to convert electric power to rotational motion, a battery system electrically connected to the at least one electric motor, and a controller coupled to the battery system. The controller includes a non-transitory computer readable memory and a processor. The memory stores a charging control software module configured to cause the processor to perform the method of: determining an optimum charging profile based at least partially on an available received charging power, an ambient temperature of the battery system, charging system constraints, and at least one driver preference.

Abstract: A method for controlling a vehicle charging and thermal operation includes monitoring at least a charge characteristic of a battery system and a thermal characteristic of the battery system. The method predicts a battery system temperature at a future time (t) based at least in part on the monitored characteristics using a predictive physics model and maintains the battery system temperature above a minimum temperature threshold and below a maximum temperature threshold by adjusting a charging profile based at least in part on the predicted battery system temperature.

Abstract: A method for generating energy-optimized travel routes with a vehicle navigation system includes generating candidate travel routes between a route origin and one or more route destinations, and then dividing each candidate travel route into a plurality of route segments. The method includes estimating expected travel speeds along each segment using cloud information and calculating an expected energy efficiency over each of the candidate travel routes using one or more vehicle-specific energy efficiency models. The travel routes are displayed via the navigation system, including a trace of the energy-optimized travel routes and an expected or relative energy efficiency along the energy-optimized travel routes. A vehicle includes the navigation system and a powertrain. A powertrain controller may control vehicle speed over a selected route to maintain an optimally energy-efficient speed.

Abstract: A direct-injection internal combustion engine is described and includes a pressure sensor that is disposed to monitor in-cylinder combustion pressure. A method, executed as a control routine in an attached controller, includes monitoring engine speed, engine load, temperature and combustion pressure. Combustion variation parameters are determined based upon the combustion pressure. A desired state for a combustion parameter can be determined based upon the engine speed, the engine load, and the temperature, and an adjustment to the desired state for the combustion parameter can be determined based upon the combustion variation parameters, wherein the adjustment to the desired state is selected to achieve acceptable states for the combustion variation parameters. Operation of the internal combustion engine is controlled based upon the desired state for the combustion parameter and the adjustment to the desired state for the combustion parameter.

Abstract: A vehicle propulsion system includes a combustion engine configured to output a propulsion torque to satisfy a propulsion demand, and a traction electric machine to generate a supplemental torque to selectively supplement the propulsion torque. The propulsion system also includes a controller programmed to forecast an acceleration demand based on at least one estimation model. The controller is also programmed to issue a command indicative of a required axle torque corresponding to the acceleration demand. The controller is further programmed to engage at least one fuel conservation action in response to the required axle torque being within a first predetermined torque threshold range.
