The present invention relates to a method for controlling an air conditioner for a vehicle, which includes a blower having a structure divided into a plurality of inlets and a plurality of outlets. The method may include: detecting or predicting, by a controller, one or more of an inside temperature of the vehicle, an outside temperature, a temperature of an engine serving as a heating source, an indoor humidity of the vehicle, CO.sub.2 concentration and rear seat passenger information; and comprehensively determining, by the controller, an outdoor state of the vehicle, an indoor state of the vehicle and a user's intention based on the detected or predicted information and a blower setting mode, and controlling an inlet door of the air conditioner according to one of a plurality of designated steps.

A control system and method for a heating system of an electric vehicle or hybrid vehicle is embodied such that when there is a heating request for a passenger compartment of the vehicle, a heating mode is set in order to heat the passenger compartment by heat from a heating circuit. In a mixed mode, excess heat in the heating circuit is output to the surroundings via a surroundings cooler in a cooling circuit, or in an excess mode it is retained in the heating system, in order to satisfy a heating request. In the mixed mode, a degree of opening of the heating circuit is set such that only a partial quantity of coolant from the heating circuit is exchanged with the cooling circuit and as a result the excess heat is output to the surroundings. The mixed mode is activated if the excess heat in the heating circuit exceeds a threshold value which is determined in accordance with the external temperature.

The present invention relates to an air conditioner for a vehicle which can block air introduced through a gap between an evaporator and an air-conditioning case and prevent condensate from overflowing toward a temperature adjusting door when condensate exceeding a drainable amount is generated. The air conditioner for a vehicle includes: an air-conditioning case having an air passageway therein; an evaporator disposed in the air passageway of the air-conditioning case; a drain hole disposed at the downstream side of the evaporator in an air flow direction to discharge condensate to the outside; a first baffle protruding upwardly from the bottom surface of the air-conditioning case; and a fourth baffle protruding upwardly from the bottom surface of the air-conditioning case and formed downstream of the first baffle in the air flow direction, wherein the first baffle and the fourth baffle are formed in such a way that at least some of them are overlapped with each other in the width direction to be formed doubly in the air flow direction.

A HVAC system for a motor vehicle having a housing, wherein the housing has an air inlet for admitting air and a cold air path in which cold air flows is provided in the housing and a warm air path in which warm air flows is provided in the housing, wherein the warm air path and the cold air path open into a mixing chamber, wherein a mixing flap is provided for controlling the proportion of cold air flowing into the mixing chamber and the proportion of warm air flowing into the mixing chamber, wherein the mixing flap is arranged rotatable about an axis and is driven by a flap actuator which has a drive shaft, wherein a gear with a nonlinear translation characteristic is provided between the mixing flap and the drive shaft.

A vehicle air conditioner is disclosed. The present invention provides the vehicle air conditioner, which: can directly control the amount of air passing through an evaporator and a heater core since a blower is disposed between the evaporator and the heater core; has front and rear seat discharge units respectively having heater cores, thereby having a simple form, minimizing energy consumption, and independently enabling four or more zones, including front and rear seats, the left and right of the front seats, and the left and right of the rear seats, to be air-conditioned; and can discharge an offensive smell to the outside during initial driving of a vehicle since the air outside a vehicle, flowing in from an air inlet, and indoor air flowing in from an inside air suction port, disposed at the center of the vehicle, are discharged to the outside of the vehicle by means of a second blower, and not by a front seat blower, for discharging the air to the rear seats.

A vehicle includes an integrated controller equipped with an advanced driver assistance system (ADAS). An air conditioner is configured to introduce air into the inside of the vehicle and to adjust a flow of the air. The air conditioner is configured to transmit the air to the integrated controller by branching an air conditioning duct that is a passage for transmitting air into the inside of the vehicle.

An air conditioning system for a vehicle and a control method thereof may include a temperature detector; an air conditioning actuator including a cooling device and a blower; and a controller connected to the temperature detector and the air conditioning actuator and including: a load determination portion determining an air conditioning load based on factors including an internal temperature or an external temperature of a vehicle detected by the temperature detector; a storage portion storing a control map that controls the air conditioning actuator according to the air conditioning load; and an update portion updating a control value, pre-stored in the control map, of the air conditioning actuator for the air conditioning load to a demand value of a user when receiving the demand value of the user for the air conditioning actuator.

The present invention relates to an air conditioner for a vehicle, which can send air-conditioned air toward a rear seat of the vehicle in order to perform air-conditioning of a front seat of the vehicle and air-conditioning of a rear seat. The air conditioner includes an air passageway formed in an air-conditioning case, wherein the air passageway includes: a rear seat cold air passageway which is a passageway that the air passed through the heat exchanger for cooling bypasses the heat exchanger for heating and flows toward a rear seat of the vehicle; and a warm air passageway which is a passageway that the air passed through the heat exchanger for cooling passes through the heat exchanger for heating and flows toward a front seat or the rear seat of the vehicle. The air conditioner includes a rear seat temperature adjusting door for controlling an amount of air flowing from the warm air passageway to the rear seat air outlet and an amount of air flowing from the rear seat cold air passageway to the rear seat air outlet.

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.

Illustrative examples of a vehicle system and associated methods may be directed to monitoring one or more vehicle components to prevent excess temperatures or heat. A thermal controller may be configured to determine a timer based on a predicted thermal input, and based on the timer, compare a temperature of the vehicle component to a temperature threshold. The thermal controller may be further configured to send an instruction to reduce the temperature of the vehicle component based on the comparison of the temperature to the temperature threshold.
