A method for calculating the estimated torque of an air conditioner for a car is provided to calculate the estimated torque to be closer to the actual torque by calculating the estimated torque in consideration of the influence that RPM has an effect on the resonator torque computation. 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 a compressor and reflecting the estimated torque; a step of classifying one cycle, from the beginning of the drive of the compressor to the finishing, into several sections according to the compressor torque variation rate; a step of calculating the estimated torque in the other operation expression according to each section; and a step of calculating the estimated torque on the driving by reflecting RPM of the car and car speed. The RPM of the car multiply VS FACTOR according to RPM FACTOR and the car speed relative to the RPM in order to reflect. The RPM FACTOR is a value of 0.3 ~ 0.9 if the car RPM is 1000~4000. The VS FACTOR is the value of 0.8~0.9 if the car speed is 5Km/h~60Km/h. |
