Calibrating the FLR Horizontal Alignment
After the physical horizontal alignment has been conducted on the chassis, there is a calibration procedure that should be implemented
prior to delivery to the customer . This can also be performed as a service function at any point in time, if required . The calibration procedure
requires the use of diagnostic software on a mobile computer that can be operated in the cab while the vehicle is in motion .
This procedure requires two people . The driver must not attempt to perform the calibration procedure while driving the vehicle .
In order to perform this procedure, the VORAD equipped vehicle must be traveling on a straight road at a speed above 30 mph behind a
target vehicle traveling in the same lane . The Bendix
™ VORAD ® -equipped vehicle should be placed into SmartCruise ® mode behind this
target vehicle . If the VORAD ® system is not Bendix ™ SmartCruise ® adaptive cruise control-equipped, position the vehicle manually 200 to
300 feet behind the target vehicle . At highway speeds, this can be approximated by the VORAD ® DIU displaying a following distance of "2
seconds" or "3 seconds ."
Double click on the option for "VORAD ® VS-400 Alignment Tests ."
Follow the steps shown on the diagnostic software .
Continue to run the truck for a period of time (2-5 min), monitoring the azimuth value . As long as the vehicle the VORAD ® system is tracking
is in the same lane, the azimuth position should be 0°, but fluctuations in driving techniques may cause the vehicle to drift +/- 0.3°. If this
value cannot be consistently kept, click the "Reset" button again and monitor the azimuth position . If the position is consistently more than
0.5° or less than -0.5°, the FLR horizontal alignment must be adjusted based on the average azimuth position.
Note: For best results it is recommended that the driver perform the alignment test for 2-5 minutes to verify correct tracking of vehicles in
the same lane .
