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 to calculate a curvature of said curved lane and a banking of said curved lane;

    using said image of said road to estimate variation of a turning angle of a steering wheel of said vehicle moving on said curved lane, and using said variation of said turning angle and a plurality of types of vehicular dynamic information to predict a rollover angle and a lateral acceleration;

    using said rollover angle, said lateral acceleration, and said vehicular dynamic information to calculate an height of a gravity center of said vehicle and a critical rollover speed when said vehicle moving on said curved lane; and

    using said height of said gravity center, said rollover angle, and said lateral acceleration to define a vehicular rollover index, substituting values of said height of said gravity center, said rollover angle, and said lateral acceleration into said vehicular rollover index, and generating a warning signal or a control signal if said vehicular rollover index exceeds a preset value.
