A cooling system for a hybrid vehicle that cools cooling medium for an air conditioner without reducing a driving performance, irrespective of a running condition. A detector detects data relating to operating conditions of a high-current device cooling circuit, a supercharger cooling circuit, a high-current device, an engine, a supercharger, and the hybrid vehicle. A controller selects one of a first water passage and a second water passage by manipulating a control valve based on the data collected by the detector, in such a manner as to maximize an amount of heat transferred from the cooling medium to high-current device cooling water or supercharger cooling water.

A vehicle air conditioner has a refrigeration cycle system including a compressor. The rotational frequency of the compressor is variably controlled, and the compressor is prevented from being operated within a resonating rotational frequency range of the compressor in which the vibration frequency of the compressor and the natural frequency of a steering device resonate with each other. When the vehicle performs automated driving, the compressor is also allowed to operate within the resonating rotational frequency range.

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.

A control system includes a refrigerant recovery module and at least one of a valve control module and a compressor control module. The refrigerant recovery module is configured to generate a refrigerant recovery signal to initiate a recovery of refrigerant from a first heat exchanger of a thermal system for an electric vehicle, and to stop the refrigerant recovery based on a temperature of refrigerant circulating through the first heat exchanger. The valve control module is configured to open a first valve to allow refrigerant to flow through the first heat exchanger in response to the refrigerant recovery signal. The compressor control module is configured to increase a speed of a compressor disposed upstream from the first heat exchanger in response to the refrigerant recovery signal.

A thermal management system control method for a vehicle is disclosed. An embodiment of the present disclosure provides a thermal management system control method for a vehicle, including: (A) a process in which a controller determines whether a track driving mode is selected based on data detected from a data detector before track driving of the vehicle, and determines an alignment position of a valve; (B) a process in which the controller, through the process (A), determines the alignment position of the valve to control a water pump or an oil pump, and operates an air conditioner; and (C) a process in which, when the air conditioner is operated through the process (B), the controller controls a battery chiller expansion valve and a compressor, and ends the control.

An Integrated thermal management valve (ITM) control apparatus of a vehicle includes a driving information generator that generates driving information of the vehicle, a refrigerant pressure measuring device that measures a refrigerant pressure of a vehicle air conditioner of the vehicle, and an ITM controller that is configured to control the ITM of the vehicle, according to the generated driving information and the measured refrigerant pressure.

A device for protecting an air conditioning system of a vehicle is configured to prevent damage to an air conditioning system due to excessive operation of a compressor or a deficit of a refrigerant by accurately determining whether to operate the compressor even without using a specific sensor that causes an increase in the manufacturing cost of a vehicle.

A control unit that controls a travelling state and an air conditioning state of a vehicle includes: a drive control unit performing a vehicle speed control and a power train control, the vehicle speed control selectively executing an acceleration operation where an engine mounted on the vehicle is operated and a deceleration operation where the engine is stopped to allow the vehicle to coast, the power train control selectively executing activation or deactivation of the engine; m and an air conditioning control unit that controls an air conditioning system provided in the vehicle to execute an air conditioning control. A content of control is changed for at least one of the vehicle speed control, the power train control and the air-conditioning control while the air conditioning system is operating, compared to a case where the air conditioning system is not operating.

In a vehicle air conditioner, a controller is configured (i) to set a target cooling temperature of air cooled by a cooling heat exchanger, (ii) to control an operation of a compressor based on a cooling temperature and the target cooling temperature of the cooling heat exchanger, and (iii) to determine a traveling state of the vehicle. The controller is configured to set a normal target temperature as the target cooling temperature when the vehicle is traveling with a normal condition, and to set a modified target temperature higher than the normal target temperature as the target cooling temperature when the vehicle starts decelerating. In addition, the controller is configured to cause the compressor to stop operating when the vehicle starts decelerating, and to cause the compressor to restart operating when the cooling temperature detected by a temperature sensor is equal to or higher than the modified target temperature.

Systems and methods are provided for controlling a hybrid powertrain of a hybrid vehicle, and may include: determining a value of a drive request for a combustion engine of the hybrid vehicle; determining electrical loading on batteries of the hybrid vehicle; adjusting operation of an accessory of the hybrid vehicle to reduce the electrical load of that accessory on the batteries of the hybrid vehicle when the drive request value is above a determined drive request threshold amount and the electrical loading on batteries of the hybrid vehicle is above a power loading threshold; and directing at least some of the power saved by adjusting operation of the accessory from the batteries of the hybrid vehicle to a drive motor of the hybrid vehicle to provide motive force for the vehicle.
