Lane Assist or Lane Departure Warning System (LDWS) are two different names describing the same technology introduced by car manufacturers to help drivers who fall asleep to keep their lane.
LDWS (lane departure warning system) is a system designed to prevent accidents caused by unintentional leaving of the lane or leaving the carriageway by alerting the driver in case exceeded of the road markings is imminent. Lane Assist and Lane Departure Warning System (LDWS) are names of the same technology, introduced by automakers to help drivers who fall asleep at the wheel to keep their lane. Full details and documentation is available on the this page.
About 17% of accidents occurring on motorways and national roads are caused by driver fatigue, which asleep at the wheel and leave the roadway, reports National Highway Traffic Safety Administration (NHTSA). Lane Assist prevents precisely inadvertent lane changes on national roads and motorways.
This technology is found in many automakers under different names. The system also works differently depending on the price of the car.
On cars more affordable when we talk about price, the system merely warn the driver who fell asleep at the wheel or who exceeded the traffic lane through light signals, audio or vibration.
On the more expensive cars, the technology is more advanced and efficient. When it detects the lane departure the system automatically reinstate the car on normal lane without the driver to intervene.
This is made possible due to the cameras that are mounted on top of the windshield that monitors travel speed and road marking. If the driver uses turn signals turn signals to change willfully the sense, lane assist system is deactivated.
The first such system was introduced by Mercedes Benz Actros on their truck in the late ’90s. The first constructor who proposed such technologies on production cars was Nissan, which in 2001 equipped Cima sedan – the Japanese version of the third generation Infiniti Q45 – with a type LDW system; three years later, the solution of combating inattention was offered and to Infiniti FX SUV, becoming the first car in the United States thus equipped. Toyota responded with Lane Monitoring System in 2002, so as in 2004, to equip the model Crown Majesta with a Lane Keeping Assist sort of technique.
However, the first electronic assistant specializing in keeping the traffic lane was implemented by Honda pn Inspire in 2003, it automatically rectifying the trajectory of the car if the driver does not take action. As European producers, only in 2005 Citroen introduced a warning system to lane departure to both on C4 and C5.
In the early 2000s, Lane departure warning system was found on several cars manufacturers like Citroen, Nissan, Honda, Toyota and BMW.
For some producers, the two assistance systems Lane Departure Warning System (LDWS) and Lane Keeping Assist System (LKAS) are separated from each other and must be enabled separately, but other manufacturers – Mercedes, for example – have integrated in such a nature as their missions to become phases of the same process, to prevent accidents.
The only thing that really matters is that both technologies have the ability to mitigate risk. And this is how …
Take, for example, if the driver can not abstain to write down something in the phone book or write a message; Therefore, its focus of maintaining direction is almost zero.
[Regardless of the security solution, however, it is a must to remember this: even supervised by an virtual "instructor" the life remains in your hands.]
