Lane Departure Warning
The Lane Departure Warning (LDW) system detects lane markings on the road surface and warns the driver of unintended lane departures. If the driver does not signal his intent to switch lanes, a warning is issued. The system can be set to warn only when the vehicle is actually crossing lane markings or to give an early warning before they’re crossed.
This system is particularly effective when you’re driving on long stretches of highway where it’s easy get distracted with music, other passengers, or just general fatigue.
LDW Main Features:
- Uses advanced camera to detect lane markings
- Gives you up to 0.5 seconds notice before crossing lane
- Provides both audio and visual alerts
- Active at speeds over 37 mph
Did you know that…
- 60% of road accident fatalities are due to lane departure*
- Drifting out of the lane causes nearly 10% of all crashes**
How Safe Drive Systems’ LDW works
Lane Departure Warning: The RD140 provides visual and audio Lane Departure Warning alerts when a vehicle drifts out-of-lane. A tone that simulates driving over rumble strips lines will sound, and the separation lines at the sides of the display will blink white, respectively.
The RD-140 LDW system consists of a camera located behind your rearview mirror, which detects the lane markings ahead of you and monitors the car’s own relative position to the lane markings.
If a vehicle unintentionally begins to leave its lane without activating the turn signal, the system generates audio and visual alerts to get the driver’s attention. Using your turn signal will override the warning.
Our LDW feature is only available on the complete RD-140 system. If you choose to get just the RD-140 RDR system, there will only be a forward collision alert and no lane departure camera. Please contact our specialists at (855) 604-6525 to learn about our different types of systems, features, pricing, and more.
RD-140 also features a Forward Collision Warning System, which uses radar to detect vehicles in front of you and alert you when you’re at risk of a collision.
- LDW may not perform as expected due to factors such as bad weather (rain, snow, fog, etc.) and road conditions (tight curves, undulations, indistinct road markings, etc.). Additionally, under some conditions, lane markings may be mistakenly detected, causing a false warning. When operating the vehicle, drivers should always pay close attention to their surroundings. It is the responsibility of the driver to take appropriate actions including course corrections.
- LDW feature relies on lane markings to operate. This feature is not designed to work on unpaved roads or roads without lane markings. If the roadway is covered with snow, leaves, fog or debris, the lane departure warning may not be able to detect the lane markings on the road. When the system cannot detect lane markings, the warning will not activate.
