More than 1 million people die in road traffic accidents every year worldwide. Nowadays, driving risks have become one of the most serious threats to life. Most traffic accidents are caused by blind spots and driver behavior. To prevent traffic accidents and live safely, YUWEI is committed to developing the latest ADAS camera and applying it to advanced driving assistance systems (ADAS), 360 AVM systems, for more accurate and timely monitoring and correction of driver behavior.

Lane Departure Warning System

What is Lane Departure Warning System (LDWS)?

Lane Departure Warning System (LDWS) is an auxiliary driving technology that uses sensors and other equipment to detect the vehicle's position and lane while traveling and determines whether the vehicle has deviated from the intended lane. If the vehicle actually deviates from the lane, the system issues a warning to remind the driver to take timely measures to correct the direction of travel. This system can reduce traffic accidents caused by driver errors or fatigue driving and improve road safety. However, it should be noted that LDWS cannot completely replace the driver's judgment and operation. Drivers still need to maintain control and responsibility for the vehicle and observe road and traffic conditions in order to take timely action to avoid potential dangers.

LDWS System Q&A

What is the relationship between ADAS and autonomous driving?

ADAS, which stands for Advanced Driver Assistance System, typically refers to the functionalities at L1 and L2 in autonomous driving. Some common features people often hear about, such as ACC (Adaptive Cruise Control), HUD (Head-Up Display), and BSM (Blind Spot Monitoring), are all part of the ADAS system.

Why is ADAS important?

ADAS can greatly improve road safety by minimizing human errors. Certain ADAS systems issue warnings when unsafe conditions arise, such as detecting a vehicle in the driver's blind spot that may pose a risk during a lane change, thereby compelling the driver to practice safe driving habits. Additionally, some ADAS systems automate driving behaviors, such as collision avoidance through autonomous emergency braking.

In fact, according to a study by Boston Consulting Group, ADAS can prevent 28% of accidents in the United States, potentially avoiding 9,900 deaths annually.

What is LDWS on a vehicle?

LDWS stands for Lane Departure Warning System. The Lane Departure Warning System (LDWS) detects lane markings on the road and warns the driver of unintentional lane departure.

What does LDWS on a dashcam mean?

Warning: Lane Departure Warning System (LDWS) functionality is provided for reference only and cannot replace your responsibility to observe all roads and driving conditions, comply with all traffic regulations, and always make safe driving judgments.

What is the difference between LDWS and FCWS?

LDWS: When enabled, the system will alert you when it detects the vehicle deviating from the designated lane. FCWS: When enabled, the system will alert you when the vehicle is traveling slowly and too close to the vehicle ahead.
