摘要： A vehicle heating, ventilation, and air conditioning (HVAC) system including a cabin air filter, a sensor for providing a sensor reading, and a controller for determining a feedback signal from the sensor reading, wherein the controller determines a cabin air filter expected blockage level from the feedback signal. The feedback signal relates to a usage modifier of the cabin air filter, wherein the controller at east partially adjusts the estimated usage the cabin air filter from the usage modifier.

摘要： A method for defogging a window of a vehicle includes steps of automatically selecting a climate control system operating mode and determining a risk of window fogging. The climate control system operating mode is selected from an outside air mode, an air-conditioning mode, and a defrost mode. A controller determines the risk of window fogging according to one or more inputs, and the same or a different controller may automatically select the climate control system operating mode. The controller is configured to increase a climate control system blower speed to increase a rate of airflow provided by the currently-actuated climate control system operating mode. The controller may sequentially advance the climate control system operating mode through the outside air mode, air-conditioning mode, and defrost mode.

摘要： A cold ambient battery chilling mode of an electric vehicle may be implemented if the vehicle battery is being charged when the ambient air temperature is low and a temperature of the battery is elevated. During cold ambient charging, coolant flows through a heater core and through a battery heat exchanger. Cold ambient air may be utilized to cool the coolant flowing through the heater core, and coolant from the heater core flows through the battery heat exchanger and cools the battery during charging. A battery chiller may be deactivated when the cold ambient battery chilling mode is activated to reduce energy consumption.

摘要： A vehicle thermal management system including an electric powertrain, a single thermal loop, and a controller is provided. The electric powertrain includes a high voltage battery. The single thermal loop is for managing thermal conditions of the high voltage battery and a vehicle cabin and may include a climate control system, a blower, and a front evaporator in fluid communication with the vehicle cabin. The controller is programmed to, responsive to detection of a climate control system off request, output a command to direct the blower to push air through a heater core to the vehicle cabin at a predetermined temperature such that a temperature within the vehicle cabin is maintained at a predetermined temperature and refrigerant continues to flow through the front evaporator. The system may include a vehicle cabin temperature sensor and an ambient temperature sensor, each in electrical communication with the controller.

摘要： A battery electric vehicle includes a passenger cabin, a refrigerant circuit adapted to cool the passenger cabin, a powertrain including a high voltage powertrain component, a coolant circuit adapted to cool the high voltage powertrain component and a control module. The refrigerant circuit includes a condenser and an evaporator. The coolant circuit includes a radiator downstream from the condenser. The control module is configured to recirculate cabin air to the passenger cabin in response to data indicating temperature of the high voltage powertrain component exceeds a predetermined threshold temperature in order to reduce the air outlet temperature at the condenser and the air inlet temperature at the radiator. A related method to cool a high voltage powertrain component of a battery electric vehicle is also disclosed.

摘要： A method for controlling a vehicle climate control system includes steps of determining that a first predetermined set of conditions are satisfied whereby a heating, ventilation, and air-conditioning (HVAC) system airflow into a passenger cabin will exceed a predetermined HVAC airflow temperature threshold and, if so, automatically implementing a first climate control system operating condition at least reducing the HVAC airflow into the passenger cabin. On determining that a second predetermined set of conditions are satisfied whereby the HVAC airflow into the passenger cabin will satisfy the predetermined HVAC airflow temperature threshold, the method includes a step of automatically implementing a second climate control system operating condition increasing the HVAC airflow into the passenger cabin. Climate control systems for implementing the described methods are provided.

摘要： Methods and systems are provided for heat sanitizing a vehicle. In one example, a method may include, responsive to receiving a request for cleaning an interior of a vehicle, adjusting a position of a sun shade based on at least one of an ambient temperature outside of the vehicle and a sun load of the vehicle, and operating a heating, ventilation, and air-conditioning (HVAC) system to heat the interior above an upper threshold temperature for a first threshold duration. In this way, the HVAC system may be advantageously used to expose the vehicle interior to temperatures that kill or inactive microbes.

摘要： A vehicle includes a traction battery, an electric machine powered by the traction battery and configured to power wheels of the vehicle, and a thermal-management system. The thermal-management system includes a battery loop, a cabin heating loop, and a valve configured to fluidly connect the battery loop and the cabin heating loop when in a first position and configured to fluidly isolate the battery loop and the cabin heating loop when in a second position. A controller is programmed to, responsive to (i) battery heating being requested, (ii) a temperature of the battery being greater than a lower threshold, and (iii) cabin heating being requested, actuate the valve to the first position to heat a cabin and the battery.

摘要： Methods and systems are provided for heat sanitizing a vehicle. In one example, a method may include, while receiving power from an external power source and responsive to receiving a request for cleaning an interior of a vehicle, operating an electric heater of a heating, ventilation, and air-conditioning (HVAC) system to heat the interior above an upper threshold temperature for a first threshold duration using the power received from the external power source. In this way, the HVAC system may be advantageously used to expose the vehicle interior to temperatures that kill or inactive microbes while vehicle battery power and fuel are conserved by using power supplied from the external power source.
