A computer-implemented process for controlling a vehicle interior includes detecting a previously defined situation that relates to an undesirable environmental condition of the vehicle interior, and assessing both a risk level and an urgency level, based on a vehicle sensor input. The process also includes generating a vehicle command based upon the detected previously defined situation, the assessed risk level, and assessed urgency level, and executing the generated vehicle command to control at least one of an engine, a window, and a heating, ventilation and air conditioning (HVAC) unit to modify an environmental condition of the vehicle interior.

Hybrid-power transport refrigeration system (200) having a fixed-speed generator (202), a refrigeration compressor (204), a power bus (208) electrically connecting the fixed-speed generator (202) to the refrigeration compressor (204), an energy storage device (220) electrically connected to the power bus (208) and arranged to receive power from the fixed-speed generator (202) in an engine-operation mode and to supply power to the refrigeration compressor (204) in a battery-operation mode, and a DC/AC variable frequency drive electrically connected between the energy storage device (220) and the refrigeration compressor (204) to convert a DC power supply from the energy storage device (220) to a variable frequency power to drive the refrigeration compressor (204) when in the battery-operation mode.

A method of controlling air-conditioning of a vehicle, which controls an air-conditioning system of a vehicle when the vehicle is in an ignition-off state during vehicle stopping or parking, may include inputting, in the ignition-off state, setting of air-conditioning time for operating an air-conditioning system of the vehicle and setting of an air-conditioning target temperature; deriving required air-conditioning energy for operating the air-conditioning system of the vehicle on the basis of the setting of the air-conditioning time and a difference between the setting of the air-conditioning target temperature and an outside temperature of the vehicle; and driving the vehicle by increasing a setting of a minimum charge amount which is secured by a battery of the vehicle to secure the required air-conditioning energy.

The delivery system includes a vehicle and a server. The vehicle includes a power storage device and a refrigerator. The server performs a delivery planning process for determining an expected delivery time. In the delivery planning process, the server is configured to transmit, to the vehicle, an inquiry as to reception of the delivery matter. When the vehicle receives the inquiry from the server, the vehicle is configured to set a receivable time period and transmit it to the server. When the vehicle sets the receivable time period, if the vehicle is in a state that the vehicle is able to receive power from the power supply facility, the vehicle is configured to set the receivable time period to be longer than the receivable time period set if the vehicle is not in the state that the vehicle is able to receive power from the power supply facility.

A system including mode, engine, and battery modules, where the mode module determines whether to operate in an engine mode or a battery mode based on parameters. The engine module, while operating in the engine mode, runs a compressor at a first speed based on a temperature within a temperature controlled container of a vehicle and permits passage of refrigerant through eutectic plates independent of the temperature. A battery, while in the engine mode, is charged based on power received from an electrical source. The battery module, while operating in the battery mode and based on the temperature, runs the compressor at a second speed and prevents passage of the refrigerant through the eutectic plates. While in the battery mode, the battery is not being charged based on power from a shore power source and the electrical source from which power is received during the engine mode.

A heat pump and a heater core are provided at a heating coolant water circuit connected to an engine. As heating thermal amount control, the control of decreasing the output of the heat pump and increasing the output of the engine with an increase in an engine outlet water temperature detected by an engine outlet water temperature sensor, thereby ensuring a target heating thermal amount. Thus, in response to a decrease in a heat generation efficiency of the heat pump with an increase in the engine outlet water temperature, the output of the heat pump is decreased so that fuel economy can be improved while the output of the engine is increased so that the target heating thermal amount can be ensured.

A vehicle heating, ventilating, and air conditioning (HVAC) system can reduce a load applied to a vehicle powertrain during certain conditions. The system can include a fixed compressor operable between an ON state and in an OFF state. Systems and methods can determine whether an engine water temperature meets a forced HVAC recirculation intake threshold. Responsive to determining that the engine water temperature meets the forced HVAC recirculation intake threshold, it can be determined if the engine water temperature meets a high water temperature threshold. Responsive to determining that the engine water temperature meets the high water temperature threshold, it can be determined if a vehicle pitch meets a vehicle pitch threshold. Responsive to determining that the vehicle pitch does not meet the vehicle pitch threshold, the compressor can be operated according to an AC cut cycle.

A method of controlling a cooling fan in a cooling system in a vehicle includes detecting presence/absence of abnormality in a communication state, measuring an output voltage level of an air-conditioner pressure transducer (APT) sensor when the abnormality in the communication state is detected, determining a cooling fan control condition based on the measured output voltage level, and controlling a cooling fan motor according to the determined cooling fan control condition.

A vehicle includes a controller configured to determine when an HVAC system is providing at least one of heating, ventilating and air conditioning to a primary zone and to determine when a drivetrain is providing energy to a power source or the power source is providing surplus energy to the drivetrain, and in response, to activate a low cost energy mode wherein the HVAC system is operated to provide the at least one of heating, ventilating and air conditioning to at least one secondary zone.

A refrigeration system for a vehicle includes a compressor in fluid communication with a condenser and an evaporator. The compressor includes a variable speed motor and employs capacity modulation using refrigerant injection. The condenser and the evaporator include variable speed fans. The refrigeration system includes a battery to supply power to the refrigeration system. The battery is charged by one or more sources of power including the vehicle. The refrigeration system includes a control module configured to monitor one or more characteristics of the battery and to control one or more operating parameters of one or more of the compressor, the condenser, and the evaporator based on the one or more characteristics of the battery.
