Abstract: In a steering assist device, a correction gain setting unit sets correction gain to one if it determines that that the sign of a lateral deviation change rate is different from that of a second derivative value of a lateral deviation. The correction gain setting unit sets the correction gain to a predetermined value that is larger than one, if it determines that that the sign of the lateral deviation change rate is the same as that of the second derivative value of the lateral deviation. A gain multiplication unit corrects a lane keep assist current value calculated by a lane keep assist current value calculation unit by multiplying the lane keep assist current value by the correction gain set by the correction gain setting unit.

The ideal vehicle model decides the proportions of use of the first and second spring reaction force torques on the basis of a distribution gain set in accordance with the difference value between the first and second spring reaction force torques. The ideal vehicle model increases the proportion of use of the second spring reaction force torque as the difference value between the first and second spring reaction force torques is increased.

Abstract: The actuator control device includes an assist control circuit for calculating a first assist component and an automatic steering control circuit for calculating a second assist component. The automatic steering control circuit is allowed to calculate the second assist component while a steering torque is less than a first threshold value. The automatic steering control circuit calculates the second assist component by performing PID control that uses an integral term obtained on the basis of an angle deviation. When the steering torque is less than the first threshold value but not less than a second threshold value, the automatic steering control circuit limits the integral term in such a manner that it is harder for the integral term to increase while the steering torque is not less than the second threshold value than while the steering torque is less than the second threshold value.
