LDWS Lane Departure Warning System for Safe Driving

Automobile Active Safety

What kind of car is the most safe?

• Only body structure, airbags, etc. to assess the impact force against the safety car, merely represents the security level of passive safety systems. With the intelligent vehicle technology development, it gradually draws away from the anti-impact ability to rely on "passive safety" escort the old concepts, and brewing a "proactive security" of the new concept.
• The key is to prevent car accident and taken to the active safety technology. If the "security line" ahead of time to the moment before the accident, I am afraid there is nobody is willing to accept the life and death with thebody and the balloon test.
  
• On the face of it, the car is the most safe which has no anaccident or can be avoided, traffic safety need active safety technology.
  

The hazard of inadvertent lane departure

• Particularly at the end of a long and strenuous working day a driver will be liable to distraction by external factors.
• A single moment of concentration loss may cause the vehicle to drift from its intended path and come in the wrong lane or leave the road at the side.
  
• Over a third of all auto accidents or critical incidents on the motorway are related to unintended lane departures.
  
• In a quarter of the motorway accidents attributed to the auto driver, drowsiness, fatigue or distraction of the driver seems to be an important factor.
  

Lane Departure Warning System

• SystemThe Lane Departure Warning System (LDWS) is intended to prevent inadvertent lane changes and roadway departure accidents by alerting the driver if a crossing of the lane markings at either side is imminent.
• LDWS is based on machine vision technology. A camera behind the windscreen is used to track the vehicle’s position relatively to the lane markings.
  
• If the vehicle is about to leave its lane at the right-hand or left-hand side, the radio is muted and a distinctive rumble strip sound is givenfrom a speaker at the corresponding side to alert the driver to steer away from that side.
  
• Nuisance warnings are prevented by system logic to recognize intentional lane changes.
   

The lane departure warning system products base on machine vision , the function is as following:
(1)LDWS ——lane departure warning system
(2)HUD ——head up display
(3)LNVS ——low lightnight vision system
(4)OSW ——over speed warning

Product Working:
The active safety product for vehicle (LDWS + HUD + LNVS + EDR), which is using high-tech processing analysis technology and sophisticated algorithms technology (calculating 15 to 25 picture per second), auxiliary to remind the driver with alarm when the vehicle happens unconscious lane departure and speed over. It will get a good picture data through visual sensing camera,then LDWS host do analysis and processing, project the car speed and lane conditions infront windshield by HUD form and output LNVS on car DVD screen. Meanwhile, the optional EDR will record related information in the SD card. In order to install easy, you'd like to choose the selection, GPS SPEED.

Installation Instructions:
InstructionsLDWS Head unite bus wire (five wire )’s connection instruction as following.
(1)Blue white wire connect with car’s ACC wire;
(2)Black wire connect with bond strap;
(3)Green yellow wire connect with the left turning light wire;
(4)Green red wire connect with the right turning light wire;
(5)White blue connect with car speed wire. (If you use the GPS speed module, we can use the GPS speed directly, and no need to connect with the speed wire.)
