Abstract
In an electric power steering system, an ECU calculates a steering angle of a steering wheel based on an output of a rotation angle sensor and an EPS gear ratio. The ECU calculates a correction amount for canceling a steering deviation caused due to a temperature change, based on a temperature of a rack shaft detected by a temperature sensor and a map stored in a memory, and corrects the correction amount by adding the correction amount to the calculated steering angle.
