Electric power steering apparatus, control method thereof and program

A control method of an electric power steering apparatus comprising:

• calculating a target current to be supplied to an electric motor applying steering assist force to a steering wheel on the basis of steering torque of the steering wheel;
• and
• when a rotation speed of the electric motor is less than a predetermined rotation speed, correcting the calculated target current to be reduced on the basis of an actual current supplied to the electric motor and a time during which the actual current is supplied, and
• when the actual current supplied to the electric motor is more than a predetermined current value, correcting the calculated target current so that the target current becomes smaller as the actual current is larger.

A program causing a computer to executing processing comprising:

• calculating a target current to be supplied to an electric motor applying steering assist force to a steering wheel on the basis of steering torque of the steering wheel;
• and
• when a rotation speed of the electric motor is less than a predetermined rotation speed, correcting the calculated target current to be reduced on the basis of an actual current supplied to the electric motor and a time during which the actual current is supplied, and
• when the actual current supplied to the electric motor is more than a predetermined current value, correcting the calculated target current so that the target current becomes smaller as the actual current is larger.
