AdvantagesofPSM
–Superiortractionandlane-holdingabilityinalldrivingsituations-evenonroadsurfaceswithvaryingfriction.
–Thesystemcompensatesforundesiredvehi-clereactions(Ferrariaeffect)whenthedriverreleasestheacceleratorpedalorbrakesonbends.Thiscompensationfunctionsuptothemaximumlateralacceleration.
–PSMactivelystabilizesthevehicleduringdynamicdrivingmaneuvers(e.g.rapidsteeringmovements,duringlanechangesoronalternatingcurves).
–Improvedbrakingstabilityincurvesandondifferentorvaryingroadsurfaces.
–Itimprovesthebrakingfunctionsandshortensthestoppingdistanceifemergencybrakingisneeded(onlyvehicleswithfour-wheeldrive).
