First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used to refer to the same components even though they are shown in different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 is a schematic block diagram of an illegal parking guide device for a vehicle according to an exemplary embodiment.

Referring to FIG. 1, the illegal parking guide device for a vehicle according to the present invention includes a camera 10, a control unit 20, a data storage unit 30, and a guide unit 40.

In FIG. 1, the camera 10 photographs a parking stop line existing on the right side and provides an input image to the controller.

The controller 20 analyzes the input image received from the camera 10 to detect line data in the input image, and compares the line data with the parking stop line stored in the data storage unit 30 to park or stop in the parking stop zone. The control signal for guiding the determination result is outputted.

The guide unit 40 receives the control signal output from the control unit 20 and transmits a result of whether or not parking is possible to the driver of the vehicle by the OSD to the speaker or the liquid crystal display.

The data storage unit 30 stores in advance a pattern relating to the line of the parking stop zone, and stores a guide record.

2 is a schematic block diagram of an illegal parking guide device for a vehicle according to another exemplary embodiment of the present invention.

Referring to FIG. 2, the illegal parking guide device for a vehicle according to the present invention includes a camera 10, a controller 20 ′, a data storage unit 30, a guide unit 40, an engine speed detection unit 50, The vehicle speed detecting unit 60 and the switch 70 are configured.

The engine speed detection unit 50 detects an engine speed variable according to a change in an engine operating state of the vehicle, and applies an engine speed detection signal corresponding to the detected engine speed to the controller 20 ′, wherein the vehicle speed The detection unit 60 changes according to the change in the driving state of the vehicle.

By detecting a variable vehicle speed and applying a vehicle speed detection signal corresponding to the detected vehicle speed to the controller 20 ′, for example, a wheel speed sensor for detecting a rotation speed of a vehicle wheel may be used.

The controller 20 ′ determines whether the vehicle is parked or stopped by the engine speed detection signal and the vehicle speed detection signal, and operates the illegal parking guide device by the switch 70 when it is determined that the vehicle is parked or stopped. Let's do it.

An operation example of the present invention configured as described above will be described in detail with reference to FIG. 3. First, when the vehicle is started and power from the battery or the vehicle generator is supplied to the entire vehicle, each component including the controller 20 'is initialized (S10).

When the vehicle is running, the engine speed detection unit 50 detects the engine speed of the vehicle and applies an engine speed detection signal corresponding to the detected engine speed of the vehicle to the controller 20 ′, and applies the vehicle speed detection unit ( In operation 60, the speed of the vehicle is sensed, and a vehicle speed signal corresponding thereto is generated and applied to the controller 20 '(S20).

At this time, the control unit 20 'detects the driving state of the vehicle (S20), when the vehicle stops or travels below a certain speed, by applying a control signal to the switch included in the control means to operate the illegal parking guide device ( S30, the camera 10 located on the right side of the vehicle starts shooting (S50).

The image photographed in the above step is received by the controller, and the controller detects line data from the input image (S60). On the other hand, the control unit compares the line data detected in the step and the parking stop line previously stored in the data storage unit (S70).

If the controller determines that the detected line data is not a parking stop line, the operation of the present invention is terminated (S80).

If the controller determines that the line data detected in the step is a parking stop line, the controller analyzes the pattern of the input image received from the camera (S90).

As a result of the analysis in the above step, if the control unit determines that the pattern of the received input image is a solid line, the control unit transmits the parking stop prohibition guidance control signal to the guide unit, and in the case of the dotted line, the parking prohibition guidance control signal is transmitted to the guide unit (S100). .

Next, the guide unit outputs the control signal received from the controller in a voice or OSD format and transmits it to the driver of the vehicle (S110 and S120).

Those skilled in the art will appreciate that the present invention can be embodied in other specific forms without changing the technical spirit or essential features of the present invention. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. The protection scope of the present invention is shown by the following claims rather than the above description, and all changes or modifications derived from the claims and their equivalents should be construed as being included in the scope of the present invention.
