摘要： The electric power steering apparatus in accordance with the present invention is achieved with an object allowing overheat protection control to function sufficiently when an IG switch is turned ON again even when the temperature estimation processing of a heating part such as a motor ends imperfectly, thereby preventing the heating part from becoming an overheated state. The electric power steering apparatus includes a power self-holding means which can control own power off after power is turned on by an IG switch, a temperature estimation means for estimating the temperature of a heating part and performing temperature control by the temperature estimate, a temperature estimation status storage means for storing predetermined data indicating the status of temperature estimation processing before the temperature estimation means stops in a storage section within the control unit, and an initial value setting means for setting the initial value of the temperature estimate on the basis of the predetermined data when the IG switch is turned ON again and the temperature estimation means is activated.
