Global competition of automotive market and affordable prices of electronic components become the major reason that automotive industries rpidly employ a large number of electric and electronic syseems to improve vehicle performance and to meet various regulations such as emission, fuel efficiency, and safety. Especially, the provision of a motor-driven steering column (MDSC) for luxury vehicle is getting popular for drivers' covenience. In this study, an MDSC is developed, which provides several intelligent features such as the manual operation for tilting and telescoping the steering wheel, and the save/recall operation for three different steering wheel positions. In addition, the over-current detecting circuit will protect the DC motors, and the diode circuitry for the power input will also protect the electric circuit of the ECU for reverese connection to power and ground.<br/>
