Description

Vehicle Event Data Recorder Black Box {Vehicle EDR (Event Date Recorder) Black Box}

The present invention relates to a vehicle event date recorder (EDR) black box system in which an event date recorder (EDR) function is added to an existing vehicle black box.

A black box is an accident recorder used to find out the cause of an accident and to prevent future accidents by analyzing data afterwards by storing all the operational conditions of the plane at the time of the accident, such as speed, altitude, and voice of the pilot. . In recent years, such a black box is also installed in a car and used to induce the driver's own safety driving as well as to identify the cause of an accident when an accident occurs.

In the past, such a black box was collected to obtain information, and the obtained information was analyzed to check the accident contents, or the information of the black box was transmitted to the management server through other relay communication devices, and the information was analyzed by the management server. Confirmed.

EDR (Event Date Recorder) is an accident record storage device that receives the signal and records the engine revolutions per minute, brake operation, and accelerator pedal operation for 5 seconds before the airbag is fired.

Suddenly suspected car accidents stand out only in automotive vehicles, and 95% of them are not mandated and disseminated in the Korean passenger car market.

In addition, the conventional vehicle black box does not receive various vehicle information such as engine RPM, accelerator pedal and brake pedal operation from the vehicle and thus cannot store important information related to the vehicle state.

In this regard, the EDR black box for a vehicle can be used as important evidence for identifying suspicion of sudden accidents that are being driven by drivers' errors.

In order to achieve the above object, the vehicle EDR black box includes a communication port for receiving information from the vehicle in addition to the function of the existing black box and a control unit for storing the received driving information of the vehicle.

The condition of the vehicle (engine RPM, accelerator pedal, brake pedal operation, etc.) can be analyzed and compared with the image data, which can be used as important evidence for identifying the cause of an accident.

BRIEF DESCRIPTION OF THE DRAWINGS The present invention is capable of various modifications and various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting of the present invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this application, the terms "comprise" or "have" are intended to indicate that there is a feature, number, step, operation, component, part, or combination thereof described in the specification, and one or more other features. It is to be understood that the present invention does not exclude the possibility of the presence or the addition of numbers, steps, operations, components, components, or a combination thereof.

Hereinafter, a vehicle black box according to an embodiment of the present invention will be described with reference to FIG. 2. 2 is a block diagram illustrating a vehicle black box according to an embodiment of the present invention.

As shown in FIG. 2, the vehicle black box 100 according to an embodiment of the present invention includes a photographing unit 110, a storage unit 120, a power supply unit 130, a communication port 140 with a vehicle, and The controller 150 is included.

 The photographing unit 110 includes at least one camera, photographs the outside or the inside of the vehicle by using each camera, and transfers the photographed image to the storage 120.

Each camera may be a CCD camera and may be installed inside or outside the vehicle.

The storage unit 120 stores the image transmitted from the photographing unit 110 and the information transmitted by the controller 150.

The power supply unit 130 applies the power of 12v supplied from the vehicle to the vehicle black box 100.

The communication port 140 with the vehicle receives a vehicle speed, an engine RPM, a gear state (N, R, 1, 2, 3, 4, etc.), a brake operating state, and the like using communication from the vehicle.

The controller 150 displays vehicle speed information, engine RPM, gear state (N, R, 1, 2, 3, 4, etc.) received through the communication port 140 with the vehicle, brake operation state, and the like. Transfer to the storage unit 120.

As such, the vehicle black box 100 of the present invention can receive various state information of the vehicle through a communication port with the vehicle, and can store the state information of the vehicle thus received, so that the cause of the accident is only stored in the image when the accident occurs. It can be used to make up for the lack of information, and can be very useful information when the vehicle condition at the time of the accident is most important in determining the cause of the accident, such as a sudden accident.

On the other hand, the present invention can be used as a product for the After Market for a vehicle that is already manufactured as a separate product from the conventional black box, can be added to the navigation of the vehicle can be used by combining the functions of the present invention It may be.

Although the configuration of the present invention has been described in detail with reference to the preferred embodiments and the accompanying drawings, this is only an example, and various modifications are possible within the scope without departing from the spirit of the present invention. Therefore, the scope of the present invention should not be limited by the illustrated embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
