• detecting, using at least a back camera mounted to a rear portion of a vehicle body, a broken line that is marked on the road and that divides the main road and the entrance ramp or the exist ramp over which the vehicle crosses as a broken line detection result;
• determining, using a vehicle control unit, a control zone of the driving assist control based on the broken line detection result;
• performing, using a vehicle control unit, the driving assist control based on the control zone, the driving assist control is a deceleration control the decelerates the vehicle when the driving assist control is performed on the exit ramp and the driving assist control is an acceleration control that accelerates the vehicle when the driving assist control is performed on the entrance ramp;
• starting the deceleration control, using the vehicle control unit, when the broken line detecting device detects a broken line that divides the main road and the exit ramp;
• and
• ending the acceleration control, using the vehicle control unit, when the broken line detecting device detects a broken line that divides the main road and the entrance ramp,
• wherein the detecting the broken line includes capturing an image of a road surface using the back camera.
