Title:
MOTOR CONTROL SYSTEM AND MOTOR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2015/129311
Kind Code:
A1
Abstract:
Configurations wherein each ECU is provided with a circuit for backing up another ECU lack versatility and increase costs. In the present invention, motor control ECUs (1-n) respectively control motors (100-n) via signal wires (L12-Ln2) that perform motor control. In addition, a dedicated substitute ECU (p) is connected to each motor (100-n) via signal wires (Lp1-Lpn) that perform motor control. A substitute control circuit part (p1) of the dedicated substitute ECU (p) runs to a network (N), is continuously receiving malfunction information and stability information via a signal wire (Lp), and detects the malfunction of the motor control ECU (1) from said information. Then the dedicated substitute ECU (p) substitutes for the motor control ECU (1) and performs a backup operation to continue control of the motor (100) via the signal wire (Lp1).
