Vehicular steering controller

A vehicular steering controller includes an operating section for operating an actuator for steering-controlling a tire angle, a consistency-determining section, and a contribution ratio-increasing section. When a steering angle of a steering wheel is greater than or equal to a predetermined angle, the consistency-determining section determines whether consistency between first steering of the vehicle corresponding to an input operation performed on the steering wheel and second steering based on the target path is greater than or equal to a predetermined value. When the operating section operates the actuator based on the input operation performed on the steering wheel, the contribution ratio-increasing section increases a contribution ratio in which the target operation amount of the actuator contributes to an actual operation amount of the actuator by the operating section, provided that the consistency is greater than or equal to the predetermined value.
