METHOD FOR CALCULATING TORQUE OF COMPRESSOR FOR AIR CONDITIONER OF VEHICLE

摘要

PURPOSE: A method for calculating an expected torque of a compressor for air conditioner of vehicle is provided to prevent the abruptness of the revolution per minute in air conditioning system on/off and starting off. CONSTITUTION: A method for calculating an expected torque comprises the following steps. The expected torque of variable capacity type swash plate compressor in which the driving force is transmitted from the engine offering the driving force for the cooling of the driving force for the vehicle traveling is calculated(S200). According to the drive torque of the engine compensated as the calculated expected torque as described above, in order to control the drive of the engine the calculated expected torque is transmitted in the engine control unit(S400). If the drive of compressor is stopped, the value which regularly diminishes from the expected torque of the compressor calculated the compressor drive on shutdown is to the compressor expected torque value(S500).
