Abstract
In a steering assist device, a lane keep assist current value calculation unit calculates, based on a lateral deviation and a lateral deviation change rate, a lane keep assist current value that makes the lateral deviation and the lateral deviation change rate closer to zero. When the steering direction represented by the sign of control steering torque is the same as the steered direction represented by the sign of the fourth lane keep assist current value, a switch unit selects zero received at its second input terminal and outputs zero as a final lane keep assist current value.
