摘要： An electric motor (7) is driven with high output at the time of low-speed running, and a steering at a high resolution is enabled at the time of fast-speed running.An electric power steering device (1) causes the electric motor (7) to generate auxiliary torque in accordance with the largeness of steering wheel torque by the steering operation of a wheel (9) made by a driver and reduces the steering wheel torque to the driver. A control device (10) drives, based on a vehicle-speed signal (Vs) from a speed sensor (11), the electric motor (7) with high output at the time of low-speed running, and enables steering at a high resolution at the time of fast-speed running without increasing an electric-motor output. Moreover, large steering wheel torque is requisite at the time of low-speed running, and a steering at a high resolution is requisite at the time of fast-speed running. Accordingly, this does not affect the steering feeling to the driver.
