Abstract
An apparatus for and a method of preventing a car from coming into collision with an object car running ahead or behind, by monitoring car running conditions in the front and rear of the car by the provision of front and rear sensors to give an alarm to the front and rear object cars when an emergency situation has monitored, sensing a slope of a road surface on which the car runs to remove an error caused by an inclination of the car, sensing a handle rotation of the car to enable the car to follow the front object car on a curved road and to be informed of situations in the front and rear of the car on the curved road, establishing a sufficient safety distance, and sensing an emergency situation occurring in the rear of the car to inform a driver of the rear object car of the emergency situation by the provision of a display. When a rotation of the handle is detected, the front and rear sensors are rotated in a direction corresponding to that of the rotation of the handle by an amount corresponding to a rotation angle of the handle, while when a slope of a road surface on which the car runs is detected, the front and rear sensors are rotated in a direction reverse to that of the …
