PROBLEM TO BE SOLVED: To provide an electric power steering device capable of resolving an insufficient assistance during a turning of a vehicle at a high speed.SOLUTION: A basic assist torque command value setting part 41 sets a basic assist torque command value Taoon the basis of a detected steering torque T detected by a torque sensor 11 and a vehicle velocity V to be detected by a vehicle speed sensor 24. A compensation amount setting part 63, when a vehicle is determined as in a high-speed traveling state by a high-speed travel state determination part 61 and when the vehicle is determined as in a turning state by a turning state determination part 62, sets an assist torque compensation amount Tac on the basis of a lateral acceleration Gy detected by a lateral acceleration sensor 25. A compensation amount addition part 43 adds the assist torque compensation amount Tac to the basic assist torque command value Tao. |
