Abstract: The present disclosure provides a method of managing thermal loads in the powertrain of an electric vehicle and controlling various electronic components of a powertrain thermal management system. The method may include heating a coolant of a powertrain coolant loop utilizing waste heat from a liquid-cooled powertrain component (e.g., an electric motor, a DC-DC converter, etc.), measuring a coolant temperature, and utilizing combined feedforward and feedback control methods for different components (pump(s), radiator fan(s), valve(s)) of the powertrain thermal management system.

Abstract: The present disclosure provides a method of managing thermal loads in an electric vehicle and controlling various electronic components of a thermal management system. The method may comprise heating a battery coolant of a battery coolant loop utilizing waste heat from a battery to form a heated battery coolant, heating a refrigerant of a battery refrigeration loop by exchanging heat with the heated battery coolant, and measuring refrigerant temperature(s) and pressure(s) at an output of a chiller. The measured temperature(s) and pressure(s) may be utilized by the thermal management system as feedback signals for performing a proportional-integral-derivative control to compute an electronic expansion valve position command.

Abstract: A method is provided for controlling an HVAC system. The method includes receiving zone airflow target values for zones of a conditioned space. The method includes accessing a duct model including a first term that describes a flow factor for a zone damper as a nonlinear function of damper position, and a second term that describes zone airflow as a function of the flow factor and a branch pressure across zone-specific branches of an air circulation path. The method includes applying the zone airflow target values to the duct model to determine a damper position set, and actuating zone dampers to respective damper positions of the damper position set. The method may also include determining a value of total airflow to achieve the zone airflow target values with a total pressure target, and causing a fan to provide conditioned air with the value of the total airflow.
