An electric power steering device includes a steering link that includes a
plurality of connected steering shafts that connect a steering wheel to a
steered wheel, a motor that provides a steering torque to assist the
steering link, a torque sensor which is mounted to one of the steering
shafts and which detects the steering torque of that steering shaft, a
steering angle sensor which is mounted to one of the steering shafts and
which detects a steering angle of that steering shaft, a calculating unit
that calculates a steering assist amount based on the steering torque
detected by the torque sensor, the steering angle detected by the steering
angle sensor, and predetermined crossed axes angles between the connected
steering shafts, and a motor controller that drives the motor so as to
apply a steering assist force to the steering link based on the steering
assist amount. As a result, it is possible to correct the torque by a
simple method.
