摘要
The present embodiments relate to an electronic power steering device, and relates to a technology for reducing a torque rise resulting from an increase in frictional force in a low-temperature situation of the electronic power steering device. According to the present embodiments, a viscous friction compensation current is calculated using a viscous gain, which has been determined according to a damping coefficient estimated from a temperature sensed in a low-temperature situation of the electronic power steering device, and a steering angular velocity, a Coulomb friction compensation current is calculated using the sensed temperature and the mount of accumulated steering angles, and the calculated viscous friction compensation current and the Coulomb friction compensation current are added to the motor driving current and then supplied such that the driver can have the same feeling of driving, even in the low-temperature situation, as that in the room-temperature situation.
