Abstract
A vehicle steering apparatus includes a steering reaction actuator that produces a steering reaction force to be applied to the manual steering unit, a steering reaction force controller that outputs a steering reaction force command value to the steering reaction force actuator, and a road surface input torque detector that detects a road surface input torque inputted to steerable road wheels from a road surface, wherein the steering reaction force controller includes a low cut-off frequency filter that extracts a low frequency component equal to or lower than a predetermined frequency from an output of the road surface input torque detector and sets the steering reaction force command value on the basis of a vehicle driving condition and an output of the low cut-off frequency filter. A vehicle steering method is also provided.
