<P>PROBLEM TO BE SOLVED: To generate a sound for positively urging surrounding persons to use caution without degrading control responsiveness of a rotary electric machine while suppressing generation of torque pulsations. <P>SOLUTION: An inverter control apparatus 60 includes a current command section 61 for commanding a current command signal corresponding to a command value and a magnetic sound command section 67 for commanding a magnetic sound signal for generating a magnetic sound resulting from vibration formed by a magnetic force of an iron core of the rotary electric machine 40 to command a superimposed signal of the magnetic sound signal and the current command signal. Because this configuration makes the current command signal and the magnetic sound signal have no mutual effect of each other, generation of torque pulsation can be suppressed without degradation in control responsiveness of the rotary electric machine 40. By superimposing a magnetic sound signal upon another, a magnetic sound is positively generated from the rotary electric machine 40, thus urging surrounding persons to use caution during low-speed running. <P>COPYRIGHT: (C)2012,JPO&INPIT |
