A control method for a vehicle includes determining whether an internal combustion engine is overheated based on driving information of the vehicle and cooling information of a passenger compartment while the vehicle is driving and an HVAC system is operating in a cooling mode, and controlling an alternator or an actuator of a switching door to reduce a cooling capacity provided by the HVAC system when it is determined that the internal combustion engine is overheated.

Control system and control method for vehicle

A compressor control apparatus and method includes: a sensor configured to detect air conditioner operation state information necessary to control engagement and disengagement of a clutch of an air conditioner compressor; an electromagnetic coil in the clutch of the air conditioner compressor configured to perform clutch engagement upon receiving battery current; a microcomputer configured to determine whether the current air conditioner operation state satisfies a clutch engagement allowance condition or a clutch disengagement condition based on the air conditioner operation state information detected by the sensor and to output an operation signal based on the result of determination; and a switch configured to be turned on or off according to the operation signal output by the microcomputer and to control supply of the battery current to the electromagnetic coil such that clutch engagement or clutch disengagement is performed.

Compressor control apparatus and method

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.

Device for protecting an air conditioning system of a vehicle

An air-conditioning control method for calculating an optimum operation amount of an air-conditioning blower in an air-conditioning system of a vehicle includes: determining a heater heat quantity after an engine of the vehicle is started under a maximum heating condition of the air-conditioning system and the air-conditioning system is turned on according to current vehicle state information and air-conditioning information; determining a lost heat quantity discharged outside the vehicle during a current air-conditioning mode; determining an effective heating energy efficiency by calculating a difference between the heater heat quantity and the lost heat quantity; calculating the optimum operation amount of the air-conditioning blower where the effective heating energy is maximized; and controlling operation of the air-conditioning blower according to the determined optimum operation amount.

Air conditioning control method for vehicle

An air-conditioning control method for dividing an indoor space of a vehicle into a plurality of zones to perform individual air-conditioning for each zone, may include selecting boarding zones occupied by passengers from the plurality of zones, checking whether the number of the boarding zones occupied by the passengers may be one, correcting a detection temperature of an incar sensor into a temperature of the boarding zone using a mixing ratio of air for air-conditioning discharged from the corresponding boarding zone with air existing in the boarding zone when the number of the boarding zones occupied by the passengers may be one, and performing individual air-conditioning on the selected boarding zones by determining a target discharge temperature based on the corrected temperature of the boarding zone and using the determined target discharge temperature.
