<P>PROBLEM TO BE SOLVED: To provide a compressor torque estimation device capable of accurately, simply and inexpensively performing estimation of a compressor torque of a refrigerating cycle in real time. <P>SOLUTION: The compressor torque estimation device of a vehicle air conditioning system which is equipped with the refrigerating cycle having a fixed displacement type compressor 5 for pressure feeding a refrigeration medium, a radiator 6, an expansion valve 9, and an evaporator 10, a high-pressure side refrigeration medium pressure detection means 7 for detecting a physical quantity relating to a high-pressure side refrigeration medium pressure to the expansion valve 9, and a clutch control means for outputting a clutch control signal. The compressor torque estimation device is provided with a main controller 31 which refers the physical quantity and the clutch control signal entering an input layer Ni of a neural network, multiplies the physical quantity and the control signal by a matrix of a weighing factor of a predetermined intermediate layer Nm respectively, adds the matrix of the constant of the predetermined intermediate layer Nm to perform one intermediate layer operation, and multiplies the operation result by the matrix of a weighing factor of an output layer No, adds the matrix of the constant of the predetermined output layer No, and calculates a compressor torque estimation value. <P>COPYRIGHT: (C)2009,JPO&INPIT |
