Apparatus for and method of preventing car collision utilizing laser
First Claim
1. An apparatus for preventing a first car from coming into collision with an object second car running ahead or behind, said first car having a bottom surface, said apparatus comprising:
- a car speed detecting unit for detecting a speed of the first car and generating a car speed detection signal;
a handle angle detecting unit for detecting a rotation of a handle equipped in the first car and for generating a handle angle detection signal indicative of a rotation angle of the handle;
a slope detecting unit including a vertical slope detecting sensor for detecting a road surface gradient by use of said vertical slope detecting sensor mounted on the bottom surface of the first car and generating a slope detection signal upon detecting a vertical slope of the road surface;
a sensing unit, comprising a front sensor and a rear sensor, for sensing a position of the object second car in front of or behind the first car;
a control unit for receiving output signals from the car speed detecting unit, the handle angle detecting unit, and the slope detecting unit and for controlling operation of said apparatus in response to the received signals and for determining an occurrence of an emergency situation in response to the position of the object second car in front of or behind the first car;
an acceleration unit for increasing the speed of the first car under control of the control unit;
a brake unit for automatically braking the first car, under control of the control unit, when the emergency situation occurs; and
a display unit for indicating the emergency situation under control of the control unit.

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 road surface slope by an amount corresponding to a gradient of the slope at a point of an estimated slope beginning time.

4. A method for preventing a first car from coming into collision with an object second car running ahead or behind, using a car-to-object distance measured by front and rear sensors utilizing a laser, comprising the steps of:
-
(A) when a rotation of a handle equipped in the first car is detected, rotating the front and rear sensors in a direction corresponding to a rotation direction of the handle by an amount corresponding to a rotation angle of the handle; and (B) when a slope of a road surface on which the first car runs is detected, deriving an estimated slope beginning time and rotating the front and rear sensors in a direction opposite to a road surface slope direction by an amount corresponding to a gradient of the slope at a point of the estimated slope beginning time. - View Dependent Claims (5, 6, 7)
