Abstract: A storage evaporator for an air conditioning system in a vehicle includes a single, unified coolant component unit which includes the coolant condenser, the compressor, and the chiller. Four coolant connections and two electrical connections are provided between the unified coolant component unit and the rest of the air conditioning system. Two of the four coolant connections are made with the coolant condenser, with one connection being provided to have coolant flow into the condenser and the other being provided to have coolant flow out of the condenser. Two of the four coolant connections are made with the chiller, with one connection being provided to have coolant flow into the chiller and the other being provided to have coolant flow out of the chiller. The two electrical connections are associated with the compressor which is an electric compressor. The electrical connections are high voltage and control lines.

Abstract: A thermal system for use in autonomous motor vehicles includes an intelligent controller that receives inputs from various sources, interprets the inputs using an algorithm that learns during the process of interpreting the inputs, and generates outputs to control system features. The intelligent controller receives key input data that includes internet data and vehicle data. This data, together with other key inputs, are provided to the input layer which determines an energy balance that identifies the desired power level and the actual power level. Once the desired and actual power levels are identified, the controller generates outputs that regulate conditions within the vehicle's interior. The intelligent controller includes algorithms that enable the thermal system to make power management predictions for maximum system efficiency.

Abstract: An HVAC module for a vehicle includes a housing having a plurality of airflow paths to guide the air that passes through a cooling unit or a heating unit. An upper discharge outlet temperature is indeterminate based on a temperature of a single temperature sensor in one of the plurality of airflow paths and a blend setting. The HVAC module includes a temperature sensor to determine a reference temperature of the air at a sensor location. The reference temperature is offset from a floor outlet temperature by a floor offset function of the blend setting. The reference temperature is offset from the upper discharge outlet temperature by an upper offset function of the blend setting.

Abstract: The disclosure describes systems and methods that pertain to interactions between a vehicle and an occupant within the vehicle. More specifically, various systems and methods for enhancing the decisions of automated vehicle applications (collectively “decision enhancement system”) are disclosed. In a safety restraint embodiment, a sensor is used to capture various sensor readings. Sensor readings are typically in the form of images. Occupant information, such as location attributes, motion attributes, and occupant category attributes can be obtained from the sensor readings. Such information can then used by the system to enhance the decisions made by various automated applications.
