Abstract
An apparatus and method for controlling motor driven power steering system, the apparatus including: a column torque sensor detecting column torque applied to a steering column of a vehicle; an MDPS logic unit deciding a first command current based on the column torque and vehicle speed; a steering angle position control unit outputting a second command current for driving an MDPS motor in an autonomous driving mode, based on a command steering angle and a current steering angle inputted from an autonomous driving system and a steering angle sensor, respectively; a driver steering intervention determination unit monitoring the column torque of the column torque sensor in an autonomous driving mode, and determining whether a driver has intervened in steering; and an output control unit deciding a final command current by applying the weight decided by the driver steering intervention determination unit to the first and second command currents.
