Here,
– threegreenLEDsstandfordistancesbetween450and300cm,
– threeyellowLEDsstandfordistancesbetween300and150cm,
– andthreeredLEDsstandfordistancesbetween0and150cm.
– TheredLEDsalsohavetwodifferentstates:
▪ IfthecorrespondingLEDashes,thedistanceisabout50cm.
▪ IftheLEDlightsupcontinuously,thedistanceisapprox.25cmorless.
TheTrailerRemoteControlalsoemitsacousticsignalsviaabuilt-inbuzzer.Similartoparkingaidsfamiliarfrom
passengercars,thissignalisemittedatevershorterintervals,throughtoacontinuoustone,whenapproaching
anobjectbehindthevehicle.
Note:Thedisplayandcontrolunitiscalleda"TrailerRemoteControl"becauseitwasintroducedwith
TailGUARD™fortrailervehicles,andbecausehereitistheidenticalunit.Inthisconguration,however,the
devicehasnothingtodowithtraileroperations.
Incertaincountries,objectsbehindthevehiclecanalsobedisplayedbyacorrespondingashingofthe
vehicle'srearoutlinemarkerlampsinsteadofviatheTrailerRemoteControl.
• Second variant:Usually,itisreasonablyrequiredthatthesystem–inadditiontothedisplayandwarning
function–alsoautomaticallystopsthereversingvehiclewhenitreachesacertainpreconguredstopping
distance.Forthispurpose,thevehicleisautonomouslybrakedviaadditionallyttedpneumaticvalves.These
valvesarecontrolledbytheElectronicExtensionModule.
Theamountofcontrolledbrakingpressureisalsodependentupontheactualvehiclespeedsothatthestopping
distancecanbeadheredtosafely.Forthisreason,theElectronicExtensionModulereceivesthespeedsignal
fromthevehicleviaacorrespondingconnectioncable.
TheElectronicExtensionModulemustalsobeconnectedtothevehicleelectricalsystemwithotherspecial
cables,forexampletocontrolthestoplightsduringanautonomousbrakingaction.
• Third variant:Here,autonomousbrakingiseffectedbythevehicle'sownservicebrakeratherthanwiththeaid
ofseparatelyttedvalves.
Todothis,thevehiclemanufacturermusthaveinstalledacorrespondingelectronicTailGUARD™interface,
viawhichtheElectronicExtensionModulecansendtherequiredbrakingrequirementstothevehicle'sbraking
system.
Thisfunctionisavailablefrom2017asaspecialoptionforsometowingvehiclesproducedbyMercedes-Benz.
Here,theElectronicExtensionModuleisconnectedwiththreespecialcablestotheinterfaceprovidedbythe
manufacturer.Thisallowstheexchangeofotherinformation,suchasthevehiclespeed,thedrivingdirection,
andthedistancetoobjectsbehindthevehicle.
Withthisthirdvariant,thefunctionalreadinessofthesystemandthedistanceinformationareindicatedonthe
displayonthevehicle'sinstrumentpanel.Theacousticwarningissoundedviathealreadyttedspeakers.This
obviatestheneedfortheTrailerRemoteControl.
