A vehicle air conditioning apparatus is provided that can prevent temperature variations of the air after the heat exchange in a radiator to reliably control the temperature of the air supplied to the vehicle interior. During the heating operation and the heating and dehumidifying operation, target degree of supercooling SCt when target air-blowing temperature TAO is a predetermined temperature or higher is set to SCt1 that is greater than SCt2 when the target air-blowing temperature TAO is lower than the predetermined temperature. When amount of air Ga supplied from indoor fan 12 is lower than a predetermined value, the target degree of supercooling SCt is corrected, which is set such that the degree of supercooling is lower than target degree of supercooling corrected when the amount of air Ga supplied from the indoor fan 12 is a predetermined value or higher.

The in-vehicle temperature control system of the present disclosure includes a low-temperature coolant circuit and a high-temperature coolant circuit that are capable of exchanging heat through a refrigerant circuit, a low-temperature side heat exchanger provided in the low-temperature coolant circuit, a high-temperature side heat exchanger provided in the high-temperature coolant circuit, and a common heat radiation unit. The in-vehicle temperature control system executes heat radiation suppression control for suppressing exhaust heat from the high-temperature side heat exchanger under a predetermined condition in which cooling in the low-temperature coolant circuit that is performed based on a state of a unit that is cooled by exhaust heat from the low-temperature side heat exchanger is prioritized, based on the state of the unit.

A vehicle heating, ventilation, and air conditioning (HVAC) system includes: a compressor; an interior condenser located on the downstream side of the compressor and disposed in an HVAC case; a heating-side expansion valve located on the downstream side of the interior condenser; a water-cooled heat exchanger located on the downstream side of the heating-side expansion valve; and a controller. The controller is configured to adjust an opening degree of the heating-side expansion valve based on a temperature difference between air flowing from the interior condenser to front seats of a vehicle cabin and air flowing from the interior condenser to rear seats of the cabin. The controller is also configured to adjust the opening degree based on an amount of heat (heat release amount) transferred from the interior condenser to the air.

A thermal management system includes a five-way valve configured to switch a first circuit mode in which a chiller and a battery are thermally connected and a second circuit mode in which the chiller and an LT radiator are thermally connected, and an ECU configured to control a compressor based on a chiller temperature and a radiator temperature. The ECU is configured to, in a case where switching between the first circuit mode and the second circuit mode is performed by controlling the five-way valve during a heating operation of a refrigeration cycle, control the compressor to reduce a temperature difference between the chiller temperature and the radiator temperature prior to the switching.

A method of remotely activating a vehicle system of a vehicle, the vehicle being part of a vehicle-share enterprise, the method including generating a control signal based on session parameters associated with a vehicle-sharing session, preconditioning parameters associated with the vehicle-sharing session, and sensor data associated with the vehicle-sharing session, where the sensor data includes vehicle sensor data from one or more sensors of the vehicle associated with the vehicle-sharing session, client device sensor data from one or more sensors of a client device, or a combination thereof. The method includes, prior to initiating the vehicle-sharing session, broadcasting the control signal to the vehicle, where the control signal is configured to selectively control the vehicle system.

A vehicle control apparatus and a method thereof are provided. The vehicle control apparatus includes a memory storing a program instruction and a processor that executes the program instruction. The processor controls a temperature of at least one warmer for emitting heat to the inside of a vehicle, based on at least one of a need for a user to intervene in driving of the vehicle, a driving function of automatically controlled in the vehicle, an event detected while the vehicle is driving, or information of the user, or any combination thereof.

A method for the thermal pre-conditioning of a vehicle having an electric drive unit and an electrical energy reservoir. The method includes at least the following step: the thermal pre-conditioning of a component of the vehicle while the electrical energy reservoir of the vehicle is connected to the external electrical energy supply.

A method and apparatus to control an air conditioning system in a passenger compartment of a road vehicle comprising the steps of detecting a body temperature of at least a part of the body of one or more occupants of the passenger compartment and transmitting the detected body temperature to the air conditioning system, which controls a plurality of ventilation devices arranged inside the passenger compartment. The method comprises the further steps of identifying the number and the position of the one or more occupants seated in the passenger compartment; determining an optimized tuning at least based on the body temperature detected by the sensor member and controlling the ventilation devices as a function of the optimized tuning.
