STEERING CONTROL DEVICE

摘要

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 curve direction steering torque detection unit programmed to detect a steering torque in a curve direction. An offset suppression unit suppresses a change in the offset amount more as a detected steering torque in the curve direction increases.
