Title:
ROTARY ELECTRIC MACHINE CONTROL DEVICE AND ELECTRIC POWER STEERING DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/147402
Kind Code:
A1
Abstract:
A rotary electric machine control device (10 to 12) controls a rotary electric machine (80) which includes a plurality of winding sets (180, 280). Inverter circuits (120, 220) are provided for corresponding winding sets (180, 280). Power supply relays (121, 221) are provided for respective systems. Control units (150, 250) are provided for respective systems. Corresponding-system monitoring units (152, 252) monitor for anomalies in a corresponding system. Other-system monitoring units (153, 253) monitor for anomalies in another system. Drive control units (151, 251), when an anomaly requiring power-feed termination occurs in the corresponding system, turn off the power supply relay (121, 221) of the corresponding system. The other system monitoring units (153, 253) acquire, via signal lines (31 to 33, 41 to 43), power supply relay information concerning the state of the power supply relay (221, 121) of the other system, and monitor for anomalies in the other system on the basis of the power supply relay information.
