Abstract
A control system includes a plurality of control devices each including an initial check unit that performs an initial check before drive control of a rotary electric machine, a transmission/reception unit that transmits/receives an end signal indicating that the initial check is ended, and a drive control unit that performs the drive control of the rotary electric machine after the initial check. The drive control unit starts the drive control of the rotary electric machine when the initial check of the corresponding control device is ended and the end signal is acquired from another control device, and starts the drive control of the rotary electric machine after a lapse of a predetermined time from the start of the initial check of the corresponding control device when the initial check of the corresponding control device is ended and the end signal is not acquired from the another control device.
