Abstract

The invention provides an electric power steering apparatus which can well maintain the steering feel of a steering disc in turning and a steering effort assist controlling apparatus. An electric power steering apparatus (11) provides a steering assist force to the steering system of a vehicle by controlling driving of an assist motor in accordance with a steering force acting on the steering wheel. The electric power steering apparatus (11) includes a yaw rate sensor (55) that obtains a measured yaw rate of the vehicle, a vehicle speed sensor (53) that detects the speed of the vehicle, a steering angle sensor (13) that detects the steering angle of the steering wheel, and a torque estimating apparatus (77) that estimates a self-aligning torque on the basis of the vehicle speed and data having a smaller absolute value among the measured yaw rate and the steering-angle standard yaw rate and that corrects the steering assist force on the basis of the estimated self-aligning torque.

Description

technical field [0001] The present invention relates to an electric power steering device and a steering wheel support control device for applying steering assist force to a steering system of a vehicle by controlling the drive of an assist motor based on a steering force acting on a steering member. Background technique [0002] Conventionally, there is known an electric power steering apparatus configured to apply steering assist force to a steering system of a vehicle by controlling the drive of an assist motor based on a steering force acting on a steering member such as a steering wheel. [0003] For example, in the electric power steering device of Patent Document 1, control is performed such that an additional friction torque to be applied to the steering wheel is set based on an actual steering angle, a target steering angle, and the like, and the additional friction torque is applied to the steering wheel. The additional friction torque changing unit changes the add...
