摘要： A method of operating a vehicle climate system includes, by a controller, responsive to a same blower motor request, operating a blower motor at a first speed responsive to a heater core isolation valve (HCIV) directing coolant used to heat a cabin to an engine. The method further includes, by the controller, responsive to the same blower motor request, operating the blower motor at a second speed less than the first speed responsive to the HCIV directing the coolant to an electric heater and not to the engine.

摘要： A vehicle includes a traction battery configured to be charged from an external power source via a vehicle charger, a transceiver configured to wirelessly transmit vehicle data to an external server and to wirelessly receive adaptive traction battery charging settings from the external server, an interface module configured to selectively override control of the vehicle charger based on the adaptive traction battery charging settings wirelessly received via the transceiver from the external server, a human-machine interface (HMI), and a controller in communication with a persistent on-board vehicle memory, the vehicle charger, the override module, and the HMI, the controller configured to receive manually entered traction battery charging settings via the HMI, store the manually entered traction battery charging settings in the persistent on-board vehicle memory, and selectively control the vehicle charger using the manually entered traction battery charging settings in response to the adaptive traction battery charging settings being unavailable.

摘要： Methods and systems for providing de-icing a heat pump exchanger and heating a vehicle cabin are presented. In one example, a climate control system that experiences icing of the exterior heat exchanger may be operated in a first mode where thermal energy from the energy storage device is used to de-ice and also heat the cabin.

摘要： A vehicle thermal management system including a refrigerant circuit, a coolant circuit, a chiller, and a controller is provided. The refrigerant circuit may include an electric air conditioning (eAC) compressor and a pressure sensor. The coolant circuit may include a high-voltage battery. The chiller selectively thermally links the circuits. The controller may be programmed to, responsive to receipt of a sensor signal indicating refrigerant pressure exiting the eAC compressor is greater than a high threshold, output a pressure sensor fault error indicating the pressure sensor is faulty. The system may further include a timer to monitor operational timing of the eAC compressor. The controller may be further programmed to direct the system to operate without monitoring the eAC compressor responsive to the timer indicating the eAC compressor has been off for a time-period less than a time threshold reflective of the eAC compressor not being in an at rest state.

摘要： Methods and systems are provided for operating a climate control system. In one example, a method for operating a vehicle climate control system includes modeling a pressure in a heat pump downstream of an exterior heat exchanger an upstream of an expansion valve. The method also includes operating the expansion valve to cool a vehicle cabin using the modeled pressure in conjunction with a temperature from a sensor positioned upstream of the expansion valve and downstream of the exterior heat exchanger.

摘要： A system for a vehicle includes an air conditioning compressor, and a controller configured to operate the compressor based on temperature value, responsive to the temperature values being faulty and refrigerant pressure values exceeding a first threshold, operate the compressor based on the refrigerant pressure values, and responsive to the refrigerant pressure values falling below a second threshold, deactivate the compressor for a rest of a drive cycle.

摘要： A heating, ventilation, and air-conditioning (HVAC) system in a hybrid or battery-electric vehicle is provided. The HVAC system includes a compressor that has its own dedicated motor to control its speed. The compressor includes an inlet pressure sensor to determine and output the suction pressure, and an outlet pressure sensor to determine and output the discharge pressure of the compressor. At least one controller can be programmed to determine the discharge-to-suction pressure ratio, and limit the operating speed of the compressor in response to the ratio exceeding a pressure-ratio-threshold. The pressure-ratio-threshold can vary based on ambient air temperature. In the event an inlet pressure sensor is not available, the operating speed of the compressor can be reduced in response to the outlet pressure exceeding an ambient-temperature-based variable threshold.

摘要： A system for a vehicle includes a traction battery, an engine, and a controller configured to inhibit requests to start the engine in response to both the vehicle being within a first radius about a previously-identified frequent destination and an available battery energy being greater than twice a total battery energy expended during a prior trip to the destination from a second radius about the destination, the second radius being smaller than the first radius.

摘要： An exemplary preconditioning method includes, among other things, preconditioning an electrified vehicle using power from an external source without charging a traction battery from the external source. An exemplary vehicle assembly includes, among other things, a conditioning system that preconditions an electrified vehicle using power from an external source, and a traction battery having a state of charge that does not increase as the conditioning system preconditions the electrified vehicle.

摘要： A thermal management system for a vehicle includes a controller. The controller pre-heats a coolant in a power electronics loop via heat transfer between the coolant and an electronic component in response to an ambient temperature being less than a threshold and a coolant temperature being less than a battery temperature. The controller also pumps the coolant through a battery loop in response to the coolant temperature exceeding the battery temperature.
