<P>PROBLEM TO BE SOLVED: To control a compressor to be operated with low noises during stopping an engine. <P>SOLUTION: In a vehicular air-conditioner 8 which has the compressor 41 mounted on a hybrid vehicle with a vehicle driving engine 4 and a vehicle driving motor 3 and adapted to be driven by a IPM motor 11, an air-conditioner ECU 10 outputs a rotating speed command value for the IPM motor 11 to a control part 14 of an inverter device, outputs a normal mode signal during operating the engine 4 and outputs a low noise mode signal during stopping the engine 4. The control part 14 executes the maximum torque control when receiving the normal mode signal and executes weak field control when receiving the low noise mode signal. <P>COPYRIGHT: (C)2004,JPO |
