Title:
MOTOR CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2018024335
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor control device that is able to match error in an amount of control between systems and able to improve motor torque ripple and NV (Noise Vibration) unlike a case where each system controls a motor independently.SOLUTION: A motor control device 4 shares at least some parameters of either one of systems. On the basis of the parameters, a first control arithmetic section 31 and a second control arithmetic section 41 calculate an amount of assist control. Thereby, on the basis of the amount of assist control, the motor drive part of each system drives a motor coil 15u and so on. That is, in both systems 30, 40, in a case where both steering torque and vehicle speed of the systems 30, 40 are normal, the assist control sections 33, 43 calculate an amount of assist control on the basis of the steering torque Th1 and the vehicle speed S1.SELECTED DRAWING: Figure 2
