A lane keeping assist system of a vehicle includes a camera and control having an image processor that processes image data captured by the camera to determine a lane boundary of a lane of a road traveled by the vehicle. The control establishes a virtual boundary line at an initial location relative to the determined lane boundary, with the initial location of the virtual boundary line at or inboard of the determined lane boundary. The control, responsive to a lateral speed of the vehicle relative to the determined lane boundary, laterally adjusts the virtual boundary line relative to the determined lane boundary. Responsive to a determination that the vehicle, when moving towards the determined lane boundary, would cross the virtual boundary line, the control at least one of (i) generates an alert to the driver of the vehicle and (ii) controls a steering system of the vehicle.
