Description

Vehicle accident warning device and method

The present invention relates to an accident warning apparatus and method of a vehicle, and particularly, to warn that an accident has occurred in the vicinity of an accident, and also, when an accident occurs, a vehicle accident warning device for automatically turning off the vehicle when driving at a certain speed. And to a method.

In recent years, the number of vehicles has increased rapidly, and the traffic accidents caused by the increase of vehicles are also increasing in proportion to the increase of vehicles.

In addition, the conventional vehicle was not equipped with a device for warning the drivers or pedestrians of the surrounding vehicles even if an accident occurred while driving.

However, as described above, the driver and pedestrians of the surrounding vehicle could not be warned, causing a chain collision accident, and also causing a hit-and-run vehicle that escaped from the eyes of witnesses. .

Therefore, the present invention is to solve such a problem, if a collision occurs in the vehicle while driving, based on the intensity of the collision to warn the occurrence of the surroundings, and also if the vehicle is traveling at a certain speed in the accident occurrence state It is an object of the present invention to provide a vehicle accident warning device and a method which can automatically turn off the vehicle to prevent hitting.

It is characterized by including.

EXAMPLE

Hereinafter, preferred embodiments of the present invention will be described with reference to FIGS. 1 and 2.

Referring to FIG. 1, an accident warning apparatus for a vehicle according to the present invention includes a collision detection unit 1 for detecting a collision generated during driving and a first storage unit 2 storing a reference value of a vehicle speed for determining an accident occurrence. )Wow; A second storage unit (3) for storing a reference value of the collision strength for determining hit and run when an accident occurs; When the start switch 4 is turned on, the detection values input from the collision detection unit 1 and the speed detection unit 5 are compared with the reference values stored in the first and second storage units 2 and 3, respectively. And a control section 8 for controlling the operation of the horn section 6 and the warning section 7 based thereon.

When the start switch 4 is turned on and a collision occurs in the vehicle while driving, the collision detection unit 1 detects the intensity of the collision and inputs a detection value to the control unit 8, and the control unit 8 stores the first storage unit. Search (2) and input the collision reference value, and then the controller 8 compares and judges the input collision detection value and the magnitude of the collision reference value, and if it is determined that the collision detection value is large, the controller 8 generates an accident. It judges that the horn (6) and the warning (7) to operate to inform that the accident around.

In addition, if an accident occurs as described above and the vehicle continues to run while the horn unit 6 and the warning unit 7 are in operation, the speed detecting unit 5 detects the current vehicle speed to detect a vehicle speed detection value. The controller 8 inputs the vehicle speed reference value by searching the second storage unit 3, and then the controller 8 compares and determines the magnitude of the input vehicle speed detection value and the vehicle speed reference value. If it is determined that the vehicle speed detection value is large, the controller 8 determines that the vehicle is hit and turns off the start of the vehicle.

Referring to FIG. 2, in step ST1, the start switch 4 is turned on. Step ST1 proceeds to step ST2, and in step ST2, the collision detection unit 1 inputs the collision detection value to the controller 8. Step ST2 proceeds to step ST3, and in step ST3, the controller 8 searches for the first storage unit 2 and inputs a collision reference value. Step ST3 proceeds to step ST4, and in step ST4, the controller 8 determines whether the collision detection value is larger than the collision reference value. If it is determined that the determination result is large, step ST4 proceeds to step ST5, and in step ST5, the control unit 8 operates the horn unit 6 and the warning unit 7.

In addition, step ST5 proceeds to step ST6, and in step ST6, the speed detector 5 inputs the vehicle speed detection value to the controller 8. Step ST6 proceeds to step ST7. In step ST7, the controller 8 searches for the second storage unit 3 and inputs a vehicle speed reference value. Step ST7 proceeds to step ST8, and in step ST8, the controller 8 determines whether the vehicle speed detection value is greater than the vehicle speed reference value. If it is determined that the determination result is large, step ST8 proceeds to step ST9, and in step ST9, the controller 8 turns off the start of the vehicle.

If it is determined in step ST4 that it is small, the process returns to step ST2. If it is determined in step ST8 that it is small, the flow returns to step ST7.

As described above, the accident warning apparatus and method of the vehicle of the present invention determines the strength of the collision when a collision occurs, and if it is determined that the accident is an accident, alerts the driver and pedestrians of the surrounding vehicle to the accident, and also generates an accident. If the vehicle is traveling at a certain speed in a state, the vehicle is automatically turned off to provide an excellent effect of preventing hit.
