Assistedlanedeparturewarningsystem
Usingacameraplacedatthetopofthewindscreentoidentifylanemarkingsontheground,thissystemscorrectsthetrajectoryofthevehiclewhile
alertingthedriverifitdetectsariskofinvoluntarycrossingofaline.
Thissystemisparticularlyusefulonmotorwaysandmainroads.
Theassistedlanedeparturewarning
system cannot, in any circumstances,
replacetheneedforvigilanceonthepart
ofthedriver.
The driver remains responsible for the
vehicleinallcircumstances.Thesystem
helpsthedriveronlywhenthereisarisk
ofthevehicleinvoluntarilywandering
fromthelaneitisbeingdrivenon.
Itdoesnotmanagethesafedriving
distance, the speed of the vehicle or the
brakes.
Thedrivermustholdthesteeringwheel
inawaythatallowscontroltobetaken
backincircumstanceswherethesystem
is not able to intervene (where there are
nolanemarkings,forexample).
Itisnecessarytoobservethedriving
regulationsandtakeabreakevery
twohours.
OperationConditions for operation
The speed of the vehicle must be between 40
and112mph(65and180km/h).
Thecarriagewaymusthaveatleastonelane
marking(solidorbroken)ontheground.
The driver must hold the wheel with both
hands.
Thechangeoftrajectoryisnotaccompaniedby
operationofthedirectionindicators.
TheESCsystemmustbeactivated.
Oncethesystemidentifiesariskofthevehicle
involuntarilycrossingoneofthelanemarkings
detected,itmakesthecorrectiontothe
trajectorynecessarytoreturnthevehicletoits
initialpath.
Thedriverwillthennoticeaturningmovement
ofthesteeringwheel.
Thiswarninglampflashesduring
trajectorycorrection.
If the driver wishes to maintain the
trajectoryofthevehicle,theycan
preventthecorrectionbykeepingafirm
griponthewheel(duringanavoiding
manoeuvre,forexample).
The correction is interrupted if the
directionindicatorsareoperated.
