Abstract

A steering control device capable of transmitting a road surface state to a driver as a steering reaction force more appropriately is provided. An ideal vehicle model (72) computes first spring reaction force torque (T sp1 * ) based on a target pinion angle (¸ p * ) and second spring reaction force torque (T sp2 * ) based on at least lateral acceleration (LA) as components of a spring component (T sp * ) of a steering assist force. The ideal vehicle model (72) combines the first and second spring reaction force torques (T sp1 * ) and (T sp2 * ) with specified proportions of use to compute the spring component (T sp * ). The ideal vehicle model (72) decides the proportions of use of the first and second spring reaction force torques (T sp1 * ) and (T sp2 * ) on the basis of a distribution gain (G ´sp ) set in accordance with the difference value between the first and second spring reaction force torques (T sp1 * ) and (T sp2 * ). The ideal vehicle model (72) increases the proportion of use of the second spring reaction force torque (T sp2 * ) as the difference value between the first and second spring reaction force torques (T sp1 * ) and (T sp2 * ) is increased.
