Abstract
An electric power steering apparatus includes a control unit for outputting an electric motor control signal V to control an electric motor for adding an auxiliary steering torque, in response to at least the manual steering torque signal T from a torque sensor TS. The control unit carries out a control to limit a maximum value of the electric motor control signal V in response to an electric motor current signal IMO sent from an electric motor current detecting unit . The control unit includes a maximum value limitation indicating unit for measuring the number of times of a maximum value limitation of the electric motor control signal V and has such a structure that conditions for starting the maximum value limitation of the control signal V are set to be more strict at a first time than those at a second time and thereafter.
