Title:
MOTOR CONTROL DEVICE, MOTOR DRIVE SYSTEM AND MOTOR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2018/012420
Kind Code:
A1
Abstract:
An ECU (motor control device) (101) is provided with multiple motor drive circuits (701, 702) and with multiple microcomputers (401, 402). The microcomputers (401, 402) operate on a microcomputer power supply generated by a power supply generation circuit (161, 162) connected to a power supply. At least one of the microcomputers (401, 402) has a stopping determination unit (531, 532) which determines when operation of the local microcomputer is about to be stopped, and transmits this information to the other microcomputer as a stop determination signal. A microcomputer which has received a stop determination signal from one or more other microcomputers actually stops operation of the local microcomputer at least on the basis of the stop determination signal of the other microcomputer.
