1. A method of automatically controlling speed of a vehicle in the vicinity of a speed bump, comprising steps of:

  • a) receiving, in a control unit coupled to a cruise control system of a vehicle, information about a speed bump from a navigation device and calculating a distance between the vehicle and the speed bump;

    b) upon determining that the calculated distance between the vehicle and the speed bump is less than a preset reference distance, determining that the vehicle is entering or has entered an area of the speed bump;

    c) upon determining that the vehicle is entering or has entered the speed bump area, computing a speed difference between a safe speed bump crossing speed set to allow the vehicle to safely drive across the speed bump and a current speed of the vehicle, and calculating a required acceleration value based on the calculated distance between the vehicle and the speed bump and on the computed speed difference; and

    d) controlling the speed of the vehicle so that the vehicle decelerates or accelerates in accordance with the calculated required acceleration value.
