Description
AUTOMOTIVE COVERING SAFETY DISTANCE ALARM
SYSTEM
Technical Field
[1] The present invention relates to a driving safe distance alarm system of a vehicle, and more particularly, to a driving safe distance alarm system of a vehicle, in which alarm sound is generated when a safe distance between a vehicle being driven and another vehicle which is driven ahead of the vehicle being driven or an obstacle is unsecured, dozing off, night driving on foggy roads or driving in the state in which a safe distance is unsecured, thereby ensuring more safer driving. Background Art
[2] As well known, while a vehicle is driven, there occur many traffic accidents when a safe distance is not secured at the time of dozing off or night driving on foggy roads. These kinds of traffic accidents frequently lead to fatal accidents.
[3] In the prior art, in order to prevent accidents due to dozing off of the above kinds of traffic accidents, a technology has been devised in which a camera is installed within a vehicle and senses dozing off in order to awaken a driver.
[4] An alarm device for preventing such dozing off adopts a method of giving warning when the angle of a driver's head is inclined. Lots of these kinds of the alarm devices have been developed and produced.
[5] However, such an alarm device has a drawback that it generates an alarm sound even when a driver's head is slightly moved at normal times, thereby making users inconvenient.
[6] In the recent high-grades vehicles, in order to solve this drawback, there is proposed a camera device that generates an alarm sound when movement of a driver's eyelid is determined to occur due to drowsiness by sensing the movement in real-time.
[7] However, in order to implement this technology, expensive devices such as a camera are necessarily used. Accordingly, this camera device is disadvantageous in that the manufacturing cost is increased and is problematic in that it has low accuracy since there is a significant difference in driver's behaviors.
[8] Further, the high-grade vehicle is equipped with a system that can maintain a distance between a vehicle being driven and another vehicle ahead of the vehicle being driven. However, the system has a high prime cost and hence has not been commercialized. In addition, the system maintains only a predetermined distance between the vehicle being driven and the other vehicle ahead of the vehicle being driven, but is not constructed to generate alarm sound or secure a safe distance suitable for a driving speed. Accordingly, the conventional vehicle had lots of problems in that it does not help prevent traffic accidents due to overspeed. Disclosure of Invention
Technical Problem
[9] Accordingly, the present invention has been made in an effort to solve the above problems occurring in the prior art, and an object of the present invention is to provide a driving safe distance alarm system of a vehicle, in which alarm sound is generated when a safe distance (a safe distance (S) = a response distance (Sl) + a braking distance (S2)) between a vehicle being driven and another vehicle which is driven ahead of the vehicle being driven or an obstacle is not secured in order to inform a driver of dozing off, night driving on fog roads or driving in the state in which a safe distance is unsecured, and when a driver presses the brake, the alarm sound is stopped in response to the braking signal. Technical Solution
[10] To achieve the above object, the present invention provides a driving safe distance alarm system of a vehicle, including an ultrasonic distance sensor installed in a bumper for sensing a distance a vehicle being driven and another vehicle which is driven ahead of the vehicle being driven or an obstacle, a speed sensor installed in a dashboard for sensing a speed of the vehicle, and a CPU coupled to the ultrasonic distance sensor and the speed sensor for calculating a safe distance (a safe distance (S) = a response distance (Sl) + a braking distance (S2)) according to a driving speed.
Advantageous Effects
[11] In accordance with this driving safe distance alarm system of a vehicle, when a safe distance between a vehicle being driven and another vehicle which is driven ahead of the vehicle being driven or an obstacle is not secured, alarm sound is generated from the buzzer. Accordingly, a driver can be informed of unsecured safe distance due to dozing off or night driving on fog roads or driving of accidental unsecured safe distance, enabling safe driving. Further, the driving safe distance alarm system of the present invention is very simple in structure and can be produced cheaply. Accordingly, the present invention has lots of advantages in that it can reduce traffic accidents and protect human life and property through the lower base of the driving safe distance alarm system. Brief Description of the Drawings
[12] Further objects and advantages of the invention can be more fully understood from the following detailed description taken in conjunction with the accompanying drawings in which:
[13] FIG. 1 is an exemplary view in which a safe distance braking alarm system according to the present invention is installed; and
[14] FIG. 2 is a systematic diagram showing an operation relationship according to an embodiment of the present invention.

Best Mode for Carrying Out the Invention
[22]
Mode for the Invention
[23] The present invention will now be described in detail with reference to the accompanying drawings.
[24] FIG. 1 is an exemplary view in which a safe distance braking alarm system according to the present invention is installed. FIG. 2 is a systematic diagram showing an operation relationship according to an embodiment of the present invention.
[25] As shown in FIG. 1, an ultrasonic distance sensor 1 for sensing a distance from a vehicle, which is driven ahead of a vehicle being driven, or an obstacle is installed in a bumper 10. A wheel speed sensor 2 for sensing the speed of the vehicle in a dashboard is connected to a CPU 3 for calculating a safe distance (a safe distance (S) = a response distance (Sl) + a braking distance (S2)) according to a driving speed.
[26] Further, a buzzer 4 is installed to generate alarm sound when a safe distance is not secured and coupled to the CPU 3. The CPU 3 receives a sound signal generated from the buzzer when a safe distance is unsecured, and also receives a release signal when a brake is pressed. The CPU 3 is also coupled to a brake signal switch 5 and receives a brake signal generated from the brake signal switch 5 when the brake is pressed. The CPU 3 is coupled to a switch 6, which is installed in an interior space of the vehicle in order to select a sliding or normal mode.
[27] An operation of the driving safe distance alarm system of the vehicle as constructed above according to the present invention is described below in detail.
[28] The sliding or normal mode is selected using the switch 6, which is installed in the interior of a vehicle, according to current road conditions in which the vehicle is driven.
[29] First, when the switch 6 is set to the normal mode, the CPU 3 calculates an appropriate speed accordingly. [30] For example, when a vehicle is driven 100 km/h, the CPU 3 calculates a safe distance
(a safe distance (S) = a response distance (Sl) + a braking distance (S2)).
[31] In this state, the ultrasonic distance sensor 1 senses a distance a vehicle being driven and another vehicle which is driven ahead of the vehicle being driven, and continuously sends the sensed signals to the CPU 3. The wheel speed sensor 2 also senses a speed of the vehicle and sends the sensed speed signals to the CPU 3.
[32] In this state, when a safe distance between a vehicle being driven and another vehicle driven ahead of the vehicle being driven becomes close to the vehicle, the CPU 3 immediately sends a signal to the buzzer 4, which then generates alarm sound.
[33] The driver is given attention according to the alarm sound of the buzzer and presses the brake pedal so as to reduce the speed of the vehicle.
[34] In this case, an electrical signal from the brake signal switch 5 is sent to the CPU 3.
In response to the electrical signal, the CPU 3 releases the alarm sound of the buzzer 4.
[35] Further, even when the switch 6 is set to the sliding mode, the remaining operations are the same as that of the above operation except that the CPU 3 calculates a safe distance in a different way. Industrial Applicability
