Abstract
Disclosed are a steering control device, a steering control method, and a steering support system including same. Particularly, the steering control device according to the present disclosure comprises: a noise frequency calculation unit for calculating the noise frequency of noise transmitted to a wheel; a noise frequency filtering unit for determining filtering degree on the basis of two or more driving modes, and filtering the noise frequency according to the filtering degree; and a reactive torque calculation unit for calculating reactive torque on the basis of the filtered noise frequency.
Claims19
A steering control device, which filters a noise transmitted from a road surface to a wheel and calculates a reactive torque, comprising:
- a noise frequency calculator configured to calculate a noise frequency of the noise transmitted to the wheel;
- a noise frequency filter, electrically connected to the noise frequency calculator, configured to determine a filtering degree based on a driving mode selected from two or more driving modes, and filter the noise frequency according to the filtering degree, wherein each of the two or more driving modes has a predetermined filtering degree;
- a reactive torque calculator, electrically connected to the noise frequency filter, configured to calculate the reactive torque based on the filtered noise frequency;
- and
- a tuner, electrically connected to the noise frequency filter, configured to output a tuning signal corresponding to a user's tuning operation,
- wherein the noise frequency filter performs a fine adjustment of the filtering degree, according to the tuning signal, from the predetermined filtering degree of the selected driving mode selected from among the two or more driving modes.
