Title:
STEERING CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/026342
Kind Code:
A1
Abstract:
This steering control system comprises a transverse gradient estimator that estimates the transverse gradient of a road surface, an assist amount calculator that calculates a first assist amount on the basis of the estimated transverse gradient, a low pass filter that outputs as a second assist amount the first assist amount after a low pass filter process has been performed on the calculated first assist amount, and a motor controller that uses the outputted second assist amount to control a motor. The low pass filter, depending on whether the second assist amount increases or the second assist amount is decreasing, switches a cutoff frequency of the low pass filter between a first cutoff frequency and a second cutoff frequency set to a higher value than the first cutoff frequency.
