METHOD FOR CALCULATING TORQUE OF COMPRESSOR

摘要

PURPOSE: A method for calculating an expected torque 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 drive of an air conditioning fan is sensed in the off-state of the air conditioning system(S200). In the state where the air conditioning system is switched off, the pressure of the operating pressure converter of the air conditioning system is stored when the air conditioning fan is driven(S300). The drive of the air conditioning system is detected. The expected torque of the compressor is produced by using a big value among the pressure of the stored operating pressure converter of the air conditioning and the driven pressure of the air conditioning system(S500). The expected torque calculating as described above is recompensed in addition to the control value for the engine drive torque(S600). The engine is controlled by using the compensated drive torque value as described above.
