The Driver Alert System is basically a “drowsiness detector” and senses if a driver drifts out of his/her lane when driving. The way it works is that a small forward-facing camera mounted behind the rearview mirror senses the position of lane markings on the road and looks for any slow drift. If the system detects any movement that fits the pattern of driver drowsiness, a small red coffee cup icon illuminates on the dash and a soft chime will sound. This is a gentle indicator to alert the driver that it might be a good idea to pull over and take a break. If the driver continues to drive and still seems fatigued, then another warning chime is issued. According to the AAA Foundation for Traffic Safety, more than 40 percent of Americans say they have fallen asleep or nodded off while driving at some point.
The Lane Keeping Alert System is designed to help drivers avoid unintentional lane changes. When the system detects the vehicle drifting close to lane markings, it will alert the driver through a vibration in the steering wheel to naturally grab the driver’s attention. This vibration can be compared to the feeling that one feels when an automobile runs over highway “rumble strips”. The system allows the driver enough time to react and steer the vehicle back into its lane. To calculate the lane position, the Lane Keeping Alert also uses data from the front camera on the windshield in addition.
Lincoln Lane Keeping Aid technology takes this previous two technologies even further by providing actual steering assist to allow the driver to steer back toward the center of the lane. Essentially the car gives the driver a steering correction to steer back to where the car should be. The system calculates the amount of steering correction required based on factors such as the distance to the lane markings, yaw angle and curve radius determined from the front camera and other positional sensors in the vehicle.
It should be noted that the sensitivity of the three system settings can be adjusted between “normal” and “increased”, which moves the warning zones in closer to the center of the lane. The intensity of the steering wheel vibrations can be adjusted as well between low, medium and high. The last-known setting for each selection is stored in memory so it does not have to be set each time the system is activated.
