Abstract
A steering control device includes a steering reaction force control unit that applies a steering reaction force to a steering unit in accordance with a steering reaction force characteristic that is based on steering torque and steering angle of the steering unit in which the steering torque increases as the steering angle increases. A curvature detection unit detects a curvature of a white line. An offset unit calculates an offset amount that increases as the detected curvature increases and that offsets the steering reaction force characteristic such that a neutral point of the steering is moved in a curve direction according to a magnitude of the detected curvature. A lateral acceleration detection unit detects a lateral acceleration of a host vehicle. An offset suppression unit suppresses an increase in the offset amount more as an absolute value of the detected lateral acceleration increases.
