Understanding Lane Departure Warning Systems Modern vehicles are incredibly easy to drive, so much so that drivers can take safety for granted. But the dangers remain, and one of the more common errors that lead to accidents today is by veering out of a lane unintentionally. This can occur when the driver is distracted or tired, leading to vehicles colliding with others on the road or simply leaving the road completely. To prevent this, lane departure warning systems monitor the vehicles position on the road and provide a warning if it begins to cross the lane markers. There are various alerts that can be used, some use an alarm sound, others flash warning lights or vibrate the seat, often there is a combination of two or more of these approaches. The idea is to refocus the driver to make the correction before the vehicle has ventured outside of the lane. This advanced technology is not just about safety for today’s road vehicles, the ability to track lane markers and know where the vehicle is in relation to them is one of the key technologies required for self-driving vehicles, and as such, Lane Departure Warning technology is a crucial component of the future of road vehicles. Get Lane Departure Warnings How does it work? Lane departure warning systems use a number of technologies to create the full system, combining cameras, sensors and software algorithms to recognize road position and car behavior. Each of these components is equally important, and include: Camera Monitoring — The vehicle camera systems monitor lane markings Detection System — The camera feed is directed to a software detection system that recognizes when the vehicle begins to cross the lane markings Alarm — Once this occurs, the detection system triggers an alarm of some kind, whether audible, visible or tactile, or a combination of the three Response — The latest lane departure systems include the ability to automatically steer the vehicle back into the lane if the alarm receives no response Discover Now! These systems are highly integrated into the vehicle, and operate most effectively where there are clear lane markings, such as a highway, and at speeds over 35 mph. While a few years ago you would only find these systems on high end vehicles, today you can find lane departure warning systems on vehicles from most major manufacturers, as you can see in the table below. Manufacturer Model System Type Special Features Toyota Camry, Corolla Lane Departure Alert Includes Steering Assist Honda Accord, Civic Road Departure Mitigation Integrates with Collision Mitigation Braking Ford Fusion, Escape Lane-Keeping System Offers lane-keeping aid and alert modes BMW 3 Series, 5 Series Lane Departure Warning Includes gentle steering adjustments Mercedes-Benz C-Class, E-Class Active Lane Keeping Assist Can intervene with corrective braking Conclusion By monitoring one of the most common causes of accidents on the road today, lane departure warning systems enhance safety and save lives. Not only do these systems provide real-time alerts for drivers, but it forms the foundation of self-drive technology and smart vehicle applications. As such, lane departure technology is crucial for the future of the automotive industry. Questions? Let’s get in touch!
