Classification: CPC B | IPC B

Claim 0:
1. A steering control device comprising at least one processor configured to:
estimate a transverse gradient of a road surface on which a vehicle travels;
calculate a first assisting amount based on the transverse gradient;
perform a low pass filter processing for the first assisting amount, and output the first assisting amount subjected to the low pass filter processing, as a second assisting amount; and
control a motor that generates a steering assist torque, using the second assisting amount,
wherein the at least one processor switches a cut-off frequency of the low pass filter processing between a first cut-off frequency and a second cut-off frequency that is set to a value higher than the first cut-off frequency, depending on whether the second assisting amount increases with time or the second assisting amount decreases with time,
wherein the first assisting amount and the second assisting amount are amounts of steering torque used to assist a driver in steering.
