Abstract:
An electric power steering device, comprising:a steering link including 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 provided on one of the steering shafts and which detects the steering torque of that steering shaft; a steering angle sensor which is provided on 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.
