PROBLEM TO BE SOLVED: To provide an electric power steering device capable of reducing a steering workload of a driver when a vehicle travels on a road (cant road) having inclination in the traverse direction.SOLUTION: An electric power steering device 10 includes a steering wheel 21, a steering actuator such as an electric motor 43, for turning steering wheels 29, 29, and control sections 42, 50 for determining the controlled variable of the steering actuator corresponding to the turning angle of the steering wheels 29, 29 according to the operation of the steering wheels 21 such as switches 21L, 21R (auxiliary operating member). The control sections 42, 50 add an additional controlled variable owing to the start of operation (for example, an additional current value determined by an additional current calculation section 50) on the controlled variable before starting operation (for example, a targeted current value determined by the motor controlling section 42), and hold the additional controlled variable constant without bringing the additional controlled variable back to zero after the operation is canceled. |
