APPARATUS AND METHOD FOR MEASURING OFFSET OF EPS MOTOR POSITION SENSOR |
| 摘要 |
The present invention relates to an apparatus for measuring an offset of an EPS motor position sensor and a method therefor, the apparatus comprising: a drive motor that drives an EPS motor at a predetermined constant speed; a back electromotive force measurement unit that measures a back electromotive force generated by the EPS motor so as to generate a back electromotive force signal; a motor position sensor that senses the rotation of the EPS motor so as to generate a position signal; and an offset calculation unit that calculates an offset value by using a difference between the back electromotive force signal measured in the back electromotive measurement unit and the position signal generated by the motor position sensor. |
