3 TailGUARD™
3.1 TailGUARD™ for trailers
TailGUARD™wasinitiallydevelopedfortrailervehiclesttedwithanEBSbrakingsystemandusedonthe
trailer.Incidentally,thisexplainswhythetrailersuseEBSEdiagnosticsoftwarefordiagnosingandconguringall
TailGUARD™systemsandputtingthemintooperation,evenwhereTailGUARD™isinstalledinthetowingvehicle
orbus.Thediagnosticsoftwareautomaticallydetectsthiswhenthesystemstartsupandswitchestotheappropriate
mode.
TwodifferentsystemsareavailablewithTailGUARD™fortrailervehicles:
 WithTailGUARDlight™,twoultrasonicsensorsareusedtomeasuretheactualdistancetotheloadingramp.The
systemdoesnotmonitortheentireareabehindthevehicle,butisonlyanaidforapproachingtheramp.
 TheotherthreeTailGUARD™variantsaresystemsformonitoringtheareabehindthevehicle.WABCO
recommendsaminimumsystemofthreesensorsonthesamelevel(thevariantTailGUARD™).Withthe
TailGUARD
ROOF
™variant,forexample,aroofovertherampcanbedetectedbytwoextraultrasonicsensors
mountedonanadditionalupperlevel.Arearareamonitoringsystemcanberealisedwiththeaidofsixultrasonic
sensorsontwolevels(TailGUARDMAX™)whichisalsocapableofdetectingsmallerobjectsbehindthevehicle.

3.2 TailGUARD™ for Truck & Bus
WithTailGUARD™fortowingvehiclesandbuses,thesamesensorisusedforthetrailervehicleswhichisusedto
monitortheareabehindthevehicle.Themostsignicantdifferenceconcernshowthesystemisintegratedinthe
vehicleelectricalsystem,andhowanautomaticbrakingactionisrealisedwhentheconguredminimumdistanceto
anobstacleisreached.
