Abstract
Control method for an electric power steering apparatus feeds back a motor current, flowing through a motor whose operation is controlled in accordance with a target motor current, so that the driving of the motor is controlled with the fed-back motor current. Peak value of the motor current is detected, and, for feedback control based on the detected peak value, the detected peak value is corrected to decrease. The thus-corrected peak value is fed back to control the motor current to conform to a target motor current value.
Claims7
A control method for an electric power steering apparatus, said control method comprising:
- a step of detecting a peak value of a motor current flowing through a steering assisting motor whose operation is controlled on the basis of a PWM signal generated in accordance with a target motor current signal;
- a step of correcting the peak value detected by said step of detecting;
- and
- a step of performing feedback control of the motor current on the basis of the peak value corrected by said step of correcting.
