摘要： An electric power steering apparatus in which, when an abnormality is generated in an electric power steering apparatus, an assist is reduced smaller than normal when a steering burden is estimated to be small; and the assist can be increased to normal and the steering burden can be sufficiently reduced when the steering burden is estimated to be large. When an abnormality is detected, an assist command is set smaller than at a normal time when there is no abnormality in a first range where the steering burden estimated by the steering burden estimation unit is small; the assist command is increased to that at a normal time in a second range where the steering burden estimated by the steering burden estimation unit is larger than the first range; and an assist torque of a motor is controlled in response to the assist command at the abnormal time.
