Next Generation lane departure warning system from Meritor Wabco


Meritor Wabco - a North American joint venture focused on the development and delivery of proven, integrated safety technology and efficiency components - has announced that its next generation lane departure warning (LDW) system will be available for fleet installation starting in October this year.

Meritor Wabco’s LDW, powered by Takata’s SafeTrak technology, is a forward-looking, vision-based system designed to monitor the road and the vehicle’s position in the lane, audibly warning the driver if the vehicle unintentionally leaves its lane.

Drivers are also alerted if the system detects lane drifts, weaving or lane changes without a turn-signal application.

Takata is the world’s leading automotive safety supplier.

Advanced image analysis algorithms enable the system to detect a wide variety of lane markings, such as dividing lines on the highway, even in unfavorable lighting or weather conditions where there are limited visible solid, dashed or reflective lane markings.

The Meritor Wabco LDW is a fully integrated compact unit with automatic calibration and integrated diagnostics that simplify setup and operation. It combines a small video camera and sophisticated machine vision software.


Drowsy driving

A valuable feature unique only to the Meritor Wabco LDW is a driver alertness warning (DAW) function that provides a warning when the system determines that the driver is drowsy, says Alan Korn, Meritor Wabco’s director of brake system integration. This is done when the system detects erratic or degraded driving based on weaving behavior within driving lines.

This feature helps drivers stay aware of dangerous driving situations caused by fatigue, he says.

The Federal Motor Carrier Safety Association (FMCSA) has cited “failure to keep in proper lane” as the third most cited reason for a fatal truck accident, an event that is commonly caused by distraction or fatigue, notes Korn. While fleet management can monitor and train on adhering to Hours of Service (HOS) regulations to mitigate drowsiness, drivers may still operate their vehicles while fatigued or inattentive.

Fatigued or inattentive driving can result in higher accident costs - an average of $91,000 for all accident types, including property damage, injury and fatal, and less favorable Compliance Safety Accountability (CSA) ratings.

The CSA weighting for a fatigued driver violation in the Driver Fatigue BASIC is the most extreme, and truck fleets are beginning to realize that LDW systems can assist them in preventing this violation.

The FMCSA has estimated the payback for LDW type systems to be as short as nine months and the payback as high as $6.55 for every dollar spent.

The National Transportation Safety Board (NTSB) has recommended the adoption of LDW due to their high efficacy.
