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

1 is a block diagram of a road driving system according to the present invention, a command application unit 100 for applying a user's command, a handle motion detection unit 110 for detecting an operation state of a handle, and an actual road. The address generator 130, the command applier 100, and the handle that generate the read address of the first to fourth memories 140 to 143 storing the image information, and the first to fourth memories 140 to 143. The microprocessor 120 controls the operation of the address generator 130 and the signal output from the microprocessor 120 to read the actual image to be outputted by the signal transmitted from the motion detector 110. A display for displaying a video source output from the multiplexer 150 and a multiplexer 150 for selectively outputting a video source output from the first to fourth memories 140 to 143 so as to be recognized by a user. The device 160 and a traveling position detector 170 for detecting a current traveling position and transmitting the same to the microprocessor 120.

The road driving system configured as described above is operated as follows.

First, the command applier 100 is generally configured to apply all the information that can be applied by the user. In particular, in order to carry out the present invention, the position information and the driving start command for the driving start point may be designated by the user. May be applied by

The handle motion detection unit 110 detects and outputs a rotation direction and a rotation angle of the handle according to a user's handle manipulation. The detection method is similar to the method performed in the existing road driving system. The output information is transmitted to the microprocessor 120.

The first memory 140 stores a plurality of straight road dedicated actual images as video source information, and the second memory 141 stores a right turn road dedicated actual image as video source information, and the third memory 142. Stores the actual image dedicated to the left turn road as the video source information, and the fourth memory 143 is configured to store the actual image dedicated to the intersection straight as the video source information. In particular, the second memory 141 stores video sources for a right turn road supported at a crossroad with a general right turn road, and a third memory 142 is also provided for a left turn road supported at a left with a general left turn road. Video sources are stored.

When the driving start point is recognized according to the command transmitted from the command application unit 100, the microprocessor 120 determines whether the corresponding driving start point is on a general straight road or a road before an intersection. As a result of the grasping, the video source output from the first memory 140 while transmitting information for reading the actual image information on the straight road at the driving position corresponding to the normal straight road to the address generator 130. Outputs the selection control signal to the multiplexer 150 so that is transmitted.

Accordingly, the address generator 130 generates an address for reading a straight line of a corresponding point among the video sources stored in the first memory 140 to the first memory 140. The first memory 140 reads the actual image of the straight road stored at the read address to be transmitted to the multiplexer 150. The multiplexer 150 is controlled by the microprocessor 120 to select a signal transmitted from the first memory 140 and transmit the selected signal to the display apparatus 160.

The display device 160 forms and displays a video source transmitted through the multiplexer 150 as a screen that can be recognized by a user.

However, when the start point of the microprocessor 120 is determined, when the road position before the intersection or the road position before the intersection is reached while driving on the straight road as described above, when the steering wheel motion detection unit 110 transmits the right turn information of the steering wheel The microprocessor 120 outputs a control signal to the address generator 130 so that the right-turning video source on the intersection line leading to the currently displayed straight road among the information stored in the second memory 141 can be read. At the same time, a control signal is output to the multiplexer 150 so that the video source output from the second memory 141 is selected and transmitted.

Accordingly, the address generator 130 outputs the corresponding read address to the second memory 141, and the multiplexer 150 selects a video source transmitted from the second memory 141 and transmits it to the display apparatus 160. .

As described above, when information indicating that the steering wheel that has been rotated to the right position is transmitted from the steering wheel motion detection unit 110 in a state in which the turning video source is output on the intersection, the microprocessor 120 displays the displayed right rotation video source on the screen. The control signal is output to the address generator 130 and the multiplexer 150 so that the screen for the subsequent straight road is connected and displayed. Accordingly, the address generator 130 generates a read address so that a corresponding straight road can be read from the first memory 140, and the multiplexer 150 displays a video source read from the first memory 140. And to be transmitted to 160. At this time, the microprocessor 120 manages the information on the correlation between the video sources stored in the first to fourth memories 140 to 143 to control the address generator 130 so that a corresponding address is generated. do. Therefore, the schematic diagram of the video source for the road driving when the right turn at the intersection point while driving the straight road is shown in Figure 2a.

When the right turn state information of the handle is transmitted from the handle motion detection unit 110 at a point other than the intersection, the microprocessor 120 may have the first memory 140 and the second memory 141 in the same manner as the right turn state at the intersection. The operation of the multiplexer 150 is controlled by reading a video source. At this time, however, the object to be read is not a right turn on the intersection, so that the information is provided in the same memory but is a video source stored in another area.

On the other hand, when the information indicating that the left steering wheel state is detected from the steering wheel operation detection unit 110 before the intersection while driving the straight road is applied to the microprocessor 120, the microprocessor 120 is currently output from the first memory 140 The control signal is output to the address generator 130 so that the left-turn video source is output on the intersection leading to the straight road, and the signal for controlling the operation of the multiplexer 150 is output.

Accordingly, the address generator 130 generates an address for reading the left turn road on the intersection corresponding to the third memory 142 storing the video source of the left turn road. The multiplexer 150 is controlled by the microprocessor 120 and transmits the video source read from the third memory 142 to the display apparatus 160.

When the information on which the steering wheel is returned to its original position is transmitted from the steering wheel motion detector 110 while the left turning road on the intersection is displayed, the microprocessor 120 is a straight line connected to the left turning video source at the currently output intersection. The control signal is output to the address generator 130 and the multiplexer 150 so that the road can be displayed. As a result, the address generator 130 and the multiplexer 150 operate in the same manner as in the above-mentioned right rotation. As such, a schematic diagram of a video source output when the left side is turned at the intersection while driving on a straight road is illustrated in FIG. 2B.

On the other hand, when the steering wheel is rotated to the right from the steering wheel motion detection unit 110 in the state that is not the intersection point while driving on the straight road, the microprocessor 120 is a video source from the same memory as the right turn on the above-mentioned intersection Control to read. Like the second memory 141, the third memory 142 stores a video source capable of supporting both a left turn on an intersection and a left turn on a general road.

In addition, when the current driving position transmitted from the driving position detecting unit 170 reaches an intersection point while driving on a straight road, if the information indicating that the right or left turning state from the steering wheel motion detecting unit 110 is detected is not transmitted, the microprocessor The driving unit 120 recognizes that the driving direction is straight and outputs a control signal so that the straight screen can be displayed at the intersection. Accordingly, the address generator 130 generates an address such that the corresponding video source is read from the fourth memory 143 that stores the video source for the straight road at the intersection, and the fourth memory 143 receives the applied address. A straight road is read from the intersection stored in the transmission to the multiplexer 150. The multiplexer 150 is controlled by the microprocessor 120 to select a video source transmitted from the fourth memory 143 and transmit the selected video source to the display apparatus 160.

If it is recognized that the current driving position passes the intersection point by the information transmitted from the driving position detecting unit 170, the microprocessor 120 reads the corresponding straight road provided in the first memory 140 and displays the same. The operation of the address generator 130 and the multiplexer 150 is controlled so as to be possible. In this way, a schematic diagram of a video source when driving straight at an intersection point while driving on a straight road is shown in FIG. 2C.

In addition, when continuing driving on the straight road, the microprocessor 120 may read the corresponding video source information stored in the first memory 140 continuously and transmit the read video source information to the display apparatus 160 through the multiplexer 150. The operations of the address generator 130 and the multiplexer 150 are controlled.

As described above, the present invention stores each road image according to a change in driving position and steering direction as a real image in a separate memory, and selectively reads and displays the road image using a real-time image according to driving conditions. Compared to displaying the driving screen, there is an advantage of improving the screen quality. In addition, there is an advantage in reducing the cost burden due to the high performance of the platform because there is no need to configure the underlying platform separately.
