Description

A CAR WITHOUT SIDE-MIRROR AND A SYSTEM OPERATING THE SAME}

The present invention relates to an automobile and a system having a side mirror removed, and more particularly, a camera provided to both sides of the vehicle to face rearward, and an image provided in the interior of the vehicle and output from the camera. And a system including a pair of display apparatuses, a motor provided to change the photographing direction of the camera, and an input module for controlling the motor to change the photographing direction of the camera. will be.

In general, a vehicle is equipped with side mirrors so that a driver can grasp the situation on the left, right or rear side of the driving lane when driving.

The side mirrors are attached to both sides of the vehicle, and the driver changes the lane safely by recognizing the driving direction and speed of other vehicles driving from the rear through the mirror attached to the body of the side mirror while the driver watches the front and left and right sides while driving. Or to maintain the safety distance of the front and rear vehicles and to perform the application safely without disturbing the operation of other vehicles driving from the rear to perform a number of essential functions that are indispensable for safe operation.

The side mirrors used in this way are generally fixed to the front left and right body surface of the head lamp or the front side of the outer surface of the door so that the driver can check the traffic situation of the rear or side.

On the other hand, the side mirrors formed on the passenger side are far from the driver's seat, so the reflection angle of the mirror that the driver can see is very small, so that the reflection angle is slightly convex from both sides of the mirror to the center to secure the driver's viewing angle. It is decisive that it is almost impossible to secure the field of vision.

In addition, when the side mirror of the driver or the passenger seat is a flat mirror, there is no refraction, thereby providing accurate distance and reflection of the shape, but a blind spot that the driver cannot see in the side of the car due to the small viewing angle is inevitably required. There is a problem that occurs.

As a result, the conventional flat side mirrors installed in the vehicle while driving have a problem of small rear viewing angle, and the central block type side mirror designed to compensate for this is another problem, which is the exact distance and angle of another vehicle from the side and the rear. Because it is difficult to grasp and the convex angle is limited due to the refraction phenomenon, which is a special phenomenon of glass material, it implies the risk of contact accidents and large accidents due to left turn, right turn, and interruption with vehicles coming from the side and rear. In order to solve this problem, when purchasing an outside mirror having an auxiliary mirror and attaching it to an existing vehicle, the adjustment means becomes cumbersome because it has to be adjusted according to physical conditions of different drivers.

Also, in recent years, an automobile system has been provided in which a camera provided at the rear of the vehicle body is operated when the vehicle is reversed to display a rear view with a display device provided therein. When using a car equipped with such a system, a user has a convenient advantage of reversing while securing a rear view through the screen without having to turn uncomfortably.

Side mirrors provided on the side of a vehicle for a long time provide another problem, which is related to the generation of wind noise due to friction with air during driving of the vehicle.

Wind blowing sound is generated by the side mirror formed to protrude to the outside, there is a problem that the noise generated inside the vehicle while driving.

The present invention has been made to solve the above problems, to provide a vehicle from which the side mirror protruding to the outside of the vehicle is removed.

To this end, by installing a camera device on the side or rear of the vehicle and displaying the image photographed using the same on the display device inside the vehicle, the same effect as that of the side mirror can be obtained.

The present invention provides the following means for solving the above problems.

To this end, by installing a camera device on the side or rear of the vehicle and displaying the image photographed using the same on the display device inside the vehicle, the same effect as that of the side mirror can be obtained.

By removing the car's side mirrors, innovative changes in the car's design can occur. You can decorate the vehicle with a different design at the location where the side mirrors are currently mounted. In addition, in the case of an automobile approaching due to a large air resistance problem, for example, in the case of a racing car, a synergy effect can be obtained by removing the side mirrors. In addition, by providing one more option to the consumer, the choice of the consumer can be expanded.

And, the safety of the user can be improved. If the user sees the display device installed directly in front of the handle without turning his head at a large angle to see the side mirror, the safety can be improved.

In addition, the user does not have to worry about the side mirror while driving. Today's cars require a lot of effort to avoid hitting oncoming cars and side mirrors when crossing a narrow alley or road.

Finally, cameras and display devices can be used in many ways. For example, when back parking, the field of view can be secured through a camera on the rear left side, which was a conventional blind spot. In addition, when not operating can also be utilized as a function for the reproduction of multimedia.

EMBODIMENT OF THE INVENTION Embodiment of this invention is described with reference to drawings. The following embodiment is an illustration for demonstrating this invention, and is not intended to limit this invention only to this embodiment. The present invention can be implemented in various forms as long as the gist of the present invention is not deviated.

In describing the present invention, when it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The terms to be described below are terms set in consideration of functions in the present invention, and may be changed according to a user's intention or custom such as an experimenter and a measurer, and the definitions should be made based on the contents throughout the present specification.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The camera is characterized by using a fisheye lens.

The display device has a zoom in and zoom out function.

1 and 2 are perspective views of a vehicle in which the side mirror according to the present invention is removed. The side mirrors were removed and cameras were replaced on either side or the rear of the car. The side mounted camera is provided to face side or rear. Although the position of the camera is shown relatively later in FIGS. 1 and 2, the scope of the present invention is not limited to the position of the camera shown in the drawing. It may be present in the part where the current side mirror is located, which is more preferable since it can acquire images up to the side.

When the side mirror is removed, a performance increase is obtained by removing the side mirror in the case of an approaching car, for example, a racing car, due to a large air resistance problem. In addition, by providing one more option to the consumer, the choice of the consumer can be expanded.

3 to 5 is a block diagram of a vehicle system from which the side mirror according to the present invention is removed.

According to an embodiment of the vehicle system in which the side mirror according to the present invention is removed, the display device, the one or more cameras 430-1, 430-2, 430-3, the input module 450, and the control module 470 Include.

Cameras are mounted on the car body or on both sides of the vehicle. The camera may be mounted at a specific point for photographing the exterior of the vehicle to photograph the rear and the side. The camera transmits image data according to the captured image to the control module 470. The camera provided on the left side of the vehicle body is a camera for the left side mirror, and the camera provided on the right is a camera for the right side mirror.

The camera may use a general CCD camera, but it is also possible to use a fisheye lens to eliminate blind spots and to secure a wide viewing angle.

The display device may be divided into a left display device 410 provided on the driver side and a right display device 412 provided on the passenger seat side, and the display device is preferably provided indoors.

In particular, the left display device 410 is provided on the left side near the driver's handle and the right display device 412 is provided on the right side near the driver's handle to secure the driver's view. This is to prevent the driver from turning too much to see the display device.

In particular, it is also possible to provide a display device on the windshield of an automobile.

It is also possible to use only one display device and divide a screen into two to simultaneously perform the functions of the left display device and the right display device.

The input module 450 is a means for receiving an input signal for operating the camera and may be variously implemented as a button, a switch, and the like. In addition, the input module 450 may be a device for adjusting a direction of the camera mounted on the outside of the vehicle. In this case, the sensor may be a direction indicator or a sensor for recognizing the steering angle of the steering wheel.

That is, when the left signal is input through the direction indicator or the steering angle of the steering wheel is input to the left side, the photographing direction of the camera mounted on the left side moves to the left side. In this case, there is an advantage that it is possible to conveniently grasp the risk situation coming from the left direction.

When the direction indicator returns to its original state, it is preferable that the camera also returns to photograph the original direction.

The camera is provided with a motor operable under the control of the control module 470 so that the direction of the camera can be changed according to the situation. Since a technology of moving a camera's shooting direction remotely using a remote controller or the like is currently applied, it will be apparent to those skilled in the art that a control module combined with a wired or wireless device can adjust the camera's shooting direction.

In addition, the input module 450 may include a direction indicator (button or stick type) for adjusting the photographing direction of the camera by the user. That is, the user may manually adjust the photographing direction of the camera by using the orientation. This can now be implemented in a similar way to adjusting the mirror orientation of the side mirror using a specific key button.

When the direction indicator of the input module 450 generates a signal to the left (or the right), the control module 470 that recognizes the signal indicates a direction control signal so that the camera located on the left side can capture the left side more than the original shooting direction. send. Thereafter, the control module 470 outputs the image data received from the camera to the display device. Of course, the control module 470 may receive image data from the camera and transmit the image data to the display device, but the camera may directly transmit the image data to the corresponding display device.

In this case, the camera transmits the image data in a data format (eg, a decoded image signal) in a form that the display apparatus can output. In the following description, it is assumed that a camera directly transmits image data to a corresponding display device.

The camera can always operate when power is supplied without control by a separate control module 470.

In addition, the image output to the display device preferably has a zoom-out function.

The control module 470 may include a data transceiver 510, an input signal recognizer 520, a camera controller 530, an image processor 540, and a main controller 550 according to a function.

The data transmission / reception unit 510 is for transmitting and receiving data and specific signals with the input module 450 and the camera, and the control module 470 may be combined with each component by wire or wirelessly. In particular, CAN (Controller Area Network) has recently been applied as a communication system for automobiles. In the automotive field, cans are typically used to exchange information between on-board electronic control units (ECUs) such as engine management systems, transmission controls, instrument packs, and body electronics. It's a microcontroller that connects the same things together.

Therefore, each component of the vehicle system from which the side mirror including the control module 470 is removed may be connected to the CAN.

The input signal recognizer 520 functions to interpret the input signal transmitted from the input module 450. That is, the input signal recognition unit 520 recognizes whether the signal is input from the direction indicator or the signal from the steering angle sensor of the steering wheel, and recognizes whether the steering wheel signal is the left or right side and the steering angle of the steering wheel. do.

The camera controller 530 controls the camera corresponding to the input signal recognized by the input signal recognizer 520 to rotate by a predetermined angle in a specific direction. In particular, the size of the angle of rotation of the camera can be adjusted according to the size of the steering angle of the handle.

The image processor 540 functions to output the image data photographed and received from each camera to the corresponding display apparatus. If the display apparatus is not provided with an image codec, the image processor 540 may decode the image data to display the image on the display apparatus and transmit the image data to the display apparatus.

Of course, the image data received from the camera itself may be decoded data.
