1. A rotating electric machine control system disposed in a vehicle and controlling rotating electric machines, at least one rotating electric machine used to power a travel of a vehicle, the rotating electric machine control system comprising:
a power control unit including
a voltage converter converting a direct current voltage from a direct current power source and outputting a converted three-phase alternating current to the at least one rotating electric machine,a current detector detecting an electric current, as a detected current value, that is output from the voltage converter to the at least one rotating electric machine in each of three phases,a voltage detector detecting the direct current voltage, as a detected voltage value, anda communicator receiving plural values detected by at least one of the current detector or the voltage detector, generating a communication frame that includes the plural values, and outputting the communication frame that includes the plural values; a control section controlling the voltage converter to output the converted three-phase alternating current to the at least one rotating electric machine which outputs a requested torque from the at least one rotating electric machine, the control section being provided separately apart from the power control unit; a multiplex communication line communicably connecting the power control unit and the control section for a transmission of the communication frame from the communicator to the control section; a rotation detector detecting a rotation position of the at least one rotating electric machine and outputting the rotation position to the control section via a line other than the multiplex communication line; and a trigger communication line communicably connecting the power control unit and the control section to transmit a trigger signal from the control section to the communicator, wherein the control section outputs the trigger signal via the trigger communication line to the communicator upon receiving the rotation position from the rotation detector, the communicator, upon receiving an input of the trigger signal, generates the communication frame by receiving at least one of a plurality of detected current values or a plurality of detected voltage values from at least one of the current detector or the voltage detector, and outputs the communication frame to the control section via the multiplex communication line, and the control section performs a preset process for a control of the voltage converter based on (i) the rotation position from the rotation detector and (ii) the communication frame at a corresponding timing that corresponds to the rotation position from the rotation detector. |
