PURPOSE: To provide a motor-driven power steering device with good steering feeling which can generate steering assist force with a good balance kept on the right and left for steering wheel operation. CONSTITUTION: This motor-driven power steering device is provided with a motor control means 12 which has an offset correction means 20 for taking in a motor current detection signal IMD (=ΔIMD) corresponding to the offset value of the motor current IM detected by a motor current detection means 14 with a target current signal ISD where motor current 13 is taken as 0 kept at 0, storing it as an offset correction signal ΔIMD, computing a deviation (IMD-ΔIMD) between the motor current detection signal IMD and the offset signal ΔIMD the target current signal ISD is a finite value, and outputting a correction current sill IMC (=IMD--ΔIMD) to a deviation determination means 17. |
