CALCULATING METHOD OF EXPECTED TORQUE FOR AIR CONDITIONER OF VEHICLE

摘要

A method for calculating the estimated torque of an air conditioner for a car is provided to prevent the RPM change due to the studying faculty of a car engine controlling system by adding a compensation value according to the operating time of the air conditioner. A method for calculating the estimated torque of an air conditioner for a car comprises: a step of calculating the torque to be generated by the drive of the car air conditioner and reflecting the calculated estimated torque; and a step of calculating the estimated torque by applying a compensation value in order to prevent the RPM decrease to be generated by the engine control property of an engine control system(200). The correction value is determined relative to the operating time of the air conditioner. The method for calculating the estimated torque reflects the correction value to the estimated torque.
