Abstract:
1. A method for preventing a vehicle from rolling over in curved lane, comprising steps: using at least two image capture devices to capture at least one image of a road before said vehicle, and using said image of said road, Equation: and Equation: x=k· 2 +m·y+b to calculate, by a processor, a curvature of said curved lane and a banking of said curved lane; using said image of said road to estimate, by the processor, variation of a turning angle of a steering wheel of said vehicle moving by Equation: {circumflex over (ζ)}=57.3L/R+Ka Equation: Equation: and Equation: using said rollover angle, said lateral acceleration, and said vehicular dynamic information to calculate, by the processor, a height of a gravity center of said vehicle by Equation: and a critical rollover speed by Equation: when said vehicle moving on said curved lane; and defining a vehicle rollover index by Equation: by using said height of said gravity center, said rollover angle, and said lateral acceleration, and generating a warning signal or a control signal if said vehicular rollover index exceeds a preset value.
