Abstract
A device for controlling a compressor of vehicles may include a sensor module including a cabin temperature sensor, an outdoor temperature sensor, an evaporator temperature sensor detecting a temperature of cooling medium in an evaporator, a vehicle speed sensor, and a brake sensor, an injector, an air conditioning system including a condenser, an evaporator, the compressor, a temperature control door controlling a temperature of air flowing into a cabin, an intake door selectively distributing an inner air or an outer air into the cabin, and a blower blowing the air to the intake door, and a controller controlling the injector and the air conditioning system, wherein the controller accumulates a cold air energy by increasing an operation of the compressor if a speed-reducing condition occurs, and the air conditioning system uses the accumulated cold air energy by decreasing the operation of the compressor if a release condition occurs.
