PURPOSE: An intelligent cruise control system for a vehicle and a method thereof are provided to detect the preceding vehicle entering a curved road conveniently by using the amplitude of a radar beam reflected from the preceding vehicle, and to perform auto-cruise safely by tracing the preceding vehicle. CONSTITUTION: An intelligent cruise control system is composed of critical distance amplitude DB(210) storing critical amplitude information on a radar reflected beam according to distance between vehicles; critical azimuth amplitude DB(220) storing critical amplitude information according to azimuth; a radar detector(110) detecting distance from the preceding vehicle, the azimuth of the preceding vehicle and the amplitude of the radar reflected beam; a steering detector(120) sensing the degree of steering; a gyro detector(130) sensing the rotational angle of the vehicle and outputting to a control unit(300); and the control unit accelerating and decelerating the vehicle by comparing distance, the angle of azimuth and the rotational angle with critical values. The auto-cruise is performed stably by detecting the preceding vehicle easily with the intelligent cruise control system.
