(PSM)
GeneralinformationregardingPSM
PSMisanactivecontrolsystemforstabilizationofthevehicleduringextremedrivingmanoeuvres.ThemostrecentversionofPSM(onlyonvehicleswithfour-wheeldrive)improvesthebrakesystemfunctionality.
Warning!

Adaptyourdrivingstyletotheprevailingroadandweatherconditions.
Obeyalltrafficlaws.
AdvantagesofPSM
–Superiortractionandlane-holdingabilityinalldrivingsituations-evenonroadsurfaceswithvaryingfriction.
–Thesystemcompensatesforundesiredvehi-clereactions(Ferrariaeffect)whenthedriverreleasestheacceleratorpedalorbrakesonbends.Thiscompensationfunctionsuptothemaximumlateralacceleration.
–PSMactivelystabilizesthevehicleduringdynamicdrivingmaneuvers(e.g.rapidsteeringmovements,duringlanechangesoronalternatingcurves).
–Improvedbrakingstabilityincurvesandondifferentorvaryingroadsurfaces.
–Itimprovesthebrakingfunctionsandshortensthestoppingdistanceifemergencybrakingisneeded(onlyvehicleswithfour-wheeldrive).
Readinessforoperation
PSMisswitchedonautomaticallyeverytimeyoustarttheengine.
Function
Sensorsatthewheels,brakes,steeringsystemandenginecontinuouslymeasure:
–Speed
–Directionoftravel(steeringangle)
–Lateralacceleration
–Rateofturnabouttheverticalaxis
PSMusesthesevaluestodeterminethedirectionoftraveldesiredbythedriver.PSMintervenesandcorrectsthecourseiftheactualdirectionofmotion
deviatesfromthedesiredcourse(steering-wheelposition):Itbrakesindividualwheelsasneeded.Inaddition,theenginepowermaybemanipulatedinordertostabilizethevehicle.

–Thevehicledeceleratesandsteering-wheelforcesarealteredasthePSMcontrolsthebrakes.
–Reducedenginepower.
–Thebrakepedalpulsatesanditspositionischangedduringbraking.Inordertoachievefullvehicledeceleration,footpressuremustbeincreasedafterbeginningofthebrakepedalpulsing.
