VBOX Lane Departure Warning Testing System
Lane Departure Warning Systems assist drivers in keeping to their lane. But in order to introduce LDW systems, manufacturers must conform to the NHTSA regulation.
This has led to the need for a reliable, accurate, and flexible way of testing and verifying Lane Departure Warning systems.
The Racelogic system allows ADAS developers to easily verify the effectiveness of their products, with real-time accurate measurement of vehicle parameters, synchronised perfectly with video.
Using a VBOX 3i R10G10, a 100Hz datalogger with RTK and GLONASS, the system is accurate to below 2cm. GPS and CAN data can be viewed real-time whilst being logged, and are displayed graphically over a video using the supplied Video VBOX (screenshot below).
What can the system log?
A wide range of parameters can be logged, analysed, and viewed in post processing or live, at a positional accuracy of 2cm.

What makes it so accurate?
The Lane Departure System uses the flagship, industry standard VBOX 3i R10G10 Data Logger.
As well as receiving GPS, the system uses Russian Glonass satellites. As Glonass operates on a number of different frequencies, it is more robust, and satellite lock can be acquired faster than GPS only systems.
In addition, the system receives corrections transmitted from a locally placed RTK differential BaseStation, which brings the positional accuracy to <2cm.
The NHTSA Lane Departure TestThe test takes place five times over three styles of road marking. A pass is granted when the LDW alert activates when a front corner of the vehicle is within 1 – 2.5 ft of crossing the lane. The VBOX systems ability to test the perpendicular distance from the vehicle front corners to lane edge at 2cm positional accuracy, along with lateral and longitudinal speed at 0.01 km/h accuracy, enables accurate testing and verification of any LDWS. |
