[0039] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The detailed description disclosed below in conjunction with the accompanying drawings is intended to describe exemplary embodiments of the present invention and is not intended to represent the only embodiment in which the present invention can be implemented. In the accompanying drawings, in order to clearly describe the present invention, parts that are not related to the description may be omitted, and the same reference numerals may be used throughout the specification to represent the same or similar constituent elements.

[0040] Figure 1FIG. 1 is a diagram showing a main configuration of a system for executing driving guidance of a vehicle according to an embodiment of the present invention.

[0041] Reference Figure 1 , a system 10 according to the present invention may include an electronic device 100 and a cloud server 200 .

[0042] The electronic device 100 is an electronic device installed in a vehicle, and can access the cloud server 200 and register the intersection driver attention warning (iDAW) service to subscribe to the corresponding service. The electronic device 100 detects a reference object from the image data related to the front of the moving vehicle, confirms the driving information of the vehicle by acquiring the vehicle interior data of the moving vehicle, and then outputs an alarm based on the reference object and the driving information. Figure 2 This is described in more detail.

[0043] The cloud server 200 receives the image data related to the front of the moving vehicle and the vehicle interior data of the moving vehicle from the electronic device 100 through communication with the electronic device 100. The cloud server 200 can learn the types of signals constituting the traffic light and the order of signal changes by learning the image data. In addition, the cloud server 200 can learn which data in the vehicle interior data changes corresponding to the changes in the traffic light by learning the image data and the vehicle interior data. To this end, the cloud server 200 can store artificial intelligence algorithms and machine learning algorithms.

[0044] Figure 2 FIG. 1 is a diagram showing a main structure of an electronic device for performing driving guidance of a vehicle according to an embodiment of the present invention.

[0045] Reference Figure 2 The electronic device 100 according to the present invention may include: a communication unit 110 , an input unit 120 , a sensor unit 130 , a camera 140 , a display unit 150 , a memory 160 and a control unit 170 .

[0046] The communication unit 110 may provide the vehicle interior data and image data acquired through communication with the sensor unit 130 and the camera 140 to the control unit 170. To this end, the communication unit 110 may perform communications such as controller area network (CAN), near field communication (NFC), Zigbee, and may perform serial communications such as RS-232.

[0047] In addition, the communication unit 110 can transmit the vehicle interior data and the image data to the cloud server 200 through communication with the cloud server 200. To this end, the communication unit 110 can perform wireless communication, such as the fifth generation communication (5G, 5th generationcommunication), long term evolution-advanced (LTE-A, long term evolution-advanced), long term evolution (LTE), wireless fidelity (Wi-Fi, wireless fidelity), etc.

[0048] The input unit 120 generates input data in response to a user input to the vehicle. To this end, the input unit 120 may include, for example but not limited to, a key pad, a dome switch, a touch panel, a touch key, and a button.

[0049] The sensor unit 130 may include a plurality of sensors for acquiring vehicle interior data, including the vehicle speed of the traveling vehicle, whether the brake pedal is input, whether the accelerator pedal is input, whether the turn signal is activated, transmission information, and whether there is a preceding vehicle. The sensor unit 130 may provide the acquired vehicle interior data to the control unit 170.

[0050] The camera 140 is disposed in the vehicle and is used to obtain image data of the vehicle's external environment. In particular, the camera 140 can obtain image data related to the front of the vehicle while it is traveling, and provide the image data to the control unit 170 .

[0051] The display unit 150 displays display data related to the operation performed in the electronic device 100. The display unit 150 includes, but is not limited to, a liquid crystal display (LCD), a light emitting diode (LED) display, an organic light emitting diode (OLED) display, a microelectromechanical system (MEMS) display, and an electronic paper display, etc. The display unit 150 can be combined with the input unit 120 and implemented as a touch screen capable of input.

[0052] The memory 160 stores an operating program for operating the electronic device 100. In particular, the memory 160 may store an algorithm for analyzing image data acquired while the vehicle is traveling. At this time, the memory 160 may store algorithms such as YOLO (you only look once), which is a deep learning algorithm for detecting signal lights in image data, and may store an algorithm for performing color model (HSV (hue, saturation, value) transformation, Canny edge detection, and Hough line transformation to detect stop lines in image data.

[0053] When the vehicle is started, the control unit 170 may confirm whether the vehicle is a vehicle that has subscribed to the driving guidance service. When the vehicle is a vehicle that has subscribed to the driving guidance service, the control unit 170 receives the image data acquired by the camera 140 and analyzes the image data. The control unit 170 may receive the vehicle internal data acquired by the sensor unit 130 through communication with the sensor unit 130. At this time, the vehicle internal data may include the vehicle speed, whether the brake pedal is input, whether the accelerator pedal is input, whether the turn signal is activated, transmission information, and whether there is a leading vehicle.

[0054] As a result of analyzing the image data, when a reference object including a signal light and a stop line is detected in the image data, the control unit 170 confirms whether the vehicle is in an exceptional situation based on the confirmed vehicle interior data. At this time, the exceptional situation may include but is not limited to a state where the right turn signal is on, a state where the emergency light is on, a state where the transmission is in P gear (parking), and a state where there is a vehicle ahead of the vehicle.

[0055] When the vehicle is not in an exceptional situation, the control unit 170 can confirm the vehicle driving information, which can confirm which state the vehicle is currently in: driving state, parking state, and deceleration state. To this end, the control unit 170 can confirm the vehicle driving information by confirming the vehicle speed, whether the brake pedal is input, and whether the accelerator pedal is input in the vehicle internal data.

[0056] The control unit 170 can provide the driver with an alarm related to vehicle driving. More specifically, when it is confirmed that the vehicle is in a driving state, the control unit 170 confirms whether the driving signal in the signal light confirmed in the image data is off. At this time, the driving signal can be a straight signal or a left turn signal. When the vehicle is in a driving state and the driving signal is off, the control unit 170 confirms whether there is a stop line in the image data when the vehicle is in a driving state. As described above, when the vehicle is in a driving state and the driving signal is off and there is a stop line in the image data, the control unit 170 provides a parking alarm so that the driver stops the vehicle.

[0057] Therefore, in the present invention, when the vehicle is turning left or driving straight and the traffic light changes from a driving signal to a warning stop signal (yellow signal) and a stop signal (red signal) and there is a stop line in the direction of travel of the vehicle, the driver can stop the vehicle safely according to the signal without violating the signal.

[0058] In addition, when it is confirmed that the vehicle is parked, the control unit 170 confirms whether the driving signal of the signal lamp confirmed in the image data is on. As described above, when the vehicle is stopped and the driving signal is on, the control unit 170 provides a departure alarm so that the driver can drive the vehicle.

[0059] Therefore, in the present invention, when the vehicle stops in the left-turn waiting area or the straight-ahead waiting area, when the traffic light changes from a stop signal to a driving signal (green signal or left-turn signal), the driver can be allowed to drive safely according to the signal.

[0060] In addition, when the vehicle is in a deceleration state, the control portion 170 does not provide an additional warning.

[0061] The control unit 170 transmits the acquired image data and vehicle interior data to the cloud server 200, so that the cloud server 200 learns the types of signals that constitute the traffic light and the order of signal changes, and learns the changes in the vehicle interior data caused by the changes in the traffic light based on the image data and the vehicle interior data.

[0062] Figure 3 is a flowchart for explaining a method for performing driving guidance of a vehicle according to an embodiment of the present invention.

[0063] Reference Figure 3 In step 301, when the vehicle is turned on (ON), the control unit 170 executes step 303. In step 303, the control unit 170 may confirm whether the vehicle is a vehicle that has subscribed to the driving guidance service. In the confirmation result of step 303, when the vehicle is a vehicle that has subscribed to the driving guidance service, the control unit 170 executes step 305, and when the vehicle is not a vehicle that has subscribed to the driving guidance service, the corresponding process ends.

[0064] In step 305, the control unit 170 receives the image data acquired by the camera 140 and analyzes the image data, and then executes step 307. In step 307, the control unit 170 may receive the vehicle interior data acquired by the sensor unit 130 through communication with the sensor unit 130. At this time, the vehicle interior data may include the vehicle speed, whether the brake pedal is input, whether the accelerator pedal is input, whether the turn signal is activated, transmission information, and whether there is a leading vehicle.

[0065] In step 309, the control unit 170 performs step 311 when the reference object is detected in the image data, and returns to step 305 when the reference object is not detected, and can continuously perform steps 305 and 307. At this time, the reference object may include a traffic light and a stop line.

[0066] In step 311, the control unit 170 confirms whether the vehicle is in an exceptional situation based on the vehicle internal data confirmed in step 307. At this time, the exceptional situation may include but is not limited to the state where the right turn signal is on, the state where the emergency light is on, the state where the transmission is in P gear (parking), and the state where there is a vehicle ahead of the vehicle. In the confirmation result of step 311, if the vehicle is in an exceptional situation, step 319 is executed, and if the vehicle is not in an exceptional situation, step 313 is executed.

[0067] In step 313, the control unit 170 confirms the vehicle driving information and executes step 315. At this time, the vehicle driving information may be information about which state the vehicle is currently in: driving state, parking state, and deceleration state. To this end, the control unit 170 may confirm the vehicle driving information by confirming the vehicle speed, whether the brake pedal is input, and whether the accelerator pedal is input in the vehicle internal data.

[0068] In step 315, the control unit 170 may provide the driver with an alert related to vehicle driving. Figure 4 This is described in more detail. Figure 4 is a detailed flowchart for explaining a method for providing an alert for driving guidance of a vehicle according to an embodiment of the present invention.

[0069] Reference Figure 4 In step 401, when it is confirmed that the vehicle is in a driving state, the control unit 170 executes step 403. In step 403, the control unit 170 confirms whether the driving signal in the signal light confirmed in the image data is off. At this time, the driving signal can be a straight signal or a left turn signal.

[0070] In the result of the confirmation in step 403, when the vehicle is in a running state and the driving signal is off, the control unit 170 executes step 405. In step 405, when the vehicle is in a running state and the driving signal is off and there is a stop line in the image data, the control unit 170 executes step 407. As described above, when the vehicle is in a running state and the driving signal is off and there is a stop line in the image data, in step 407, the control unit 170 provides a parking alarm to allow the driver to stop the vehicle, and can return to Figure 3 Step 317.

[0071] Therefore, in the present invention, when the vehicle is turning left or driving straight and the signal light changes from a driving signal to a warning stop signal (yellow signal) and a stop signal (red signal) and there is a stop line in the driving direction of the vehicle, the driver can stop the vehicle safely according to the signal without violating the signal. In addition, when the driving signal is not confirmed to be off in step 403 and the stop line is not confirmed in step 405, the control unit 170 can return to Figure 3 Step 317.

[0072] When it is confirmed in step 401 that the vehicle is not in a driving state, the control unit 170 executes step 409. When it is confirmed in step 409 that the vehicle is in a parking state, the control unit 170 may execute step 411, and when it is confirmed that the vehicle is not in a parking state, the control unit 170 may execute step 415.

[0073] In step 411, when the vehicle is in a parked state and the driving signal is on, the control unit 170 executes step 413. As described above, if the driving signal is on when the vehicle is in a parked state, in step 413, the control unit 170 provides a departure alarm to allow the driver to drive the vehicle and can return to the Figure 3 Step 317.

[0074] Thus, in the present invention, when the vehicle stops in the left turn waiting area or the straight waiting area, when the signal light changes from the stop signal to the driving signal (green signal or left turn signal), the driver can be allowed to drive safely according to the signal. Figure 3 Step 317.

[0075] When it is confirmed in step 409 that the vehicle is not in a parking state, the control unit 170 executes step 415. In step 415, the control unit 170 confirms that the vehicle is in a deceleration state and returns to the Figure 3 Step 317.

[0076] Then, in step 317, the control unit 170 transmits the image data and the vehicle interior data acquired in steps 305 and 307 to the cloud server 200. At this time, the cloud server 200 can learn the types of signals constituting the traffic light and the order of signal changes based on the image data, and can learn the changes in the vehicle interior data generated according to the changes in the traffic light based on the image data and the vehicle interior data.

[0077] In step 319, the control unit 170 detects that the vehicle's startup is turned off. When the vehicle's startup is turned off, the control unit 170 may end the corresponding process. When the vehicle's startup is not turned off, the control unit 170 may execute steps 305 to 317 again.

[0078] Figures 5 to 7 It is a diagram for explaining the order of providing an alarm according to a change of a signal in a four-color signal light according to an embodiment of the present invention.

[0079] Figures 5 to 7 An example of a four-color traffic light with signals changing in different orders is shown, where R represents a red signal, Y represents a yellow signal, L represents a left turn signal, and G represents a straight ahead signal. Taking into account both the image data and the vehicle internal data, when the left turn flasher is on while the traffic light and the stop line are confirmed in the image data, the control unit 170 can confirm that the vehicle wants to turn left, and when the left turn flasher is not on while the traffic light and the stop line are confirmed, the control unit 170 can confirm that the vehicle wants to go straight ahead. In addition, when Figures 5 to 7 When the signal light shown by the solid line changes, an alert related to driving guidance may be provided to the driver, whereas when the signal light shown by the dotted line changes, no additional alert may be provided to the driver.

[0080] like Figure 5 As shown in part (a) of FIG. 1 , when the green signal is on and the green signal is off and the yellow signal is on, the control unit 170 can provide a parking warning to the driver. When the yellow signal is off and the red signal and the left turn signal are on at the same time while the left turn flasher is on, the control unit 170 can provide a driving warning to the driver so that the driver can turn left. In addition, when the left turn signal is off while the left turn flasher is on, the control unit 170 can provide a parking warning to the driver.

[0081] like Figure 5As shown in part (b) of FIG. 1 , when the green signal is on and the green signal is off and the yellow signal is on, the control unit 170 may provide a parking warning to the driver. In addition, when the yellow signal is off and the red signal is on, the control unit 170 does not provide an additional warning. In addition, when the left turn signal is on with the left turn flasher on, the control unit 170 may provide a driving warning to the driver so that the driver can turn left. In addition, when the left turn signal is off with the left turn flasher on, the control unit 170 may provide a parking warning to the driver.

[0082] like Figure 5 As shown in part (c) of FIG. 1 , when the left turn signal is on while the green signal is on and the left turn flasher is on, the control unit 170 can provide a driving warning to the driver. When the green signal and the left turn signal are off and the yellow signal is on while the left turn flasher is on, the control unit 170 can provide a parking warning to the driver.

[0083] like Figure 5 As shown in part (d) of FIG. 1 , when the left turn signal is on while the green signal is on and the left turn flasher is on, the control unit 170 can provide a driving warning to the driver. When the green signal is off and the yellow signal is on while the left turn flasher is not on, the control unit 170 can provide a stop warning to the driver who is driving straight. In addition, when the left turn signal is off and the yellow signal is on while the left turn flasher is on, the control unit 170 can provide a stop warning to the driver.

[0084] like Figure 6 As shown in part (a) of FIG. 1 , when the left turn signal and the green signal are on, and then both the left turn signal and the green signal are off and the yellow signal is on, the control unit 170 can provide a stop warning to the driver who wants to go straight or turn left.

[0085] like Figure 6 As shown in part (b) of FIG. 1 , when the left turn signal and the green signal are on, the left turn signal is off and the yellow signal is on, the control unit 170 can provide a stop warning to the driver who wants to turn left. Subsequently, when the green signal is off and the yellow signal is on, the control unit 170 can provide a stop warning to the driver who wants to go straight.

[0086] like Figure 6 As shown in part (c) of FIG. 1 , when the green signal is off and the yellow signal is on while the left turn signal and the green signal are on, the control unit 170 can provide a stop warning to the driver who wants to go straight. When the red signal and the left turn signal are on, the left turn signal is off and the yellow signal is on, the control unit 170 can provide a stop warning to the driver who wants to turn left.

[0087] like Figure 7 As shown in part (a) of FIG. 1 , when the red signal and the left turn signal are on, the red signal is off and the green signal is on, the control unit 170 can provide a departure warning to the driver. When the left turn signal and the green signal are off and the yellow signal is on, the control unit 170 can provide a stop warning to the driver who wants to go straight or turn left.

[0088] like Figure 7 As shown in part (b) of FIG. 1 , when the red signal and the left turn signal are on, the red signal is off and the green signal is on, the control unit 170 can provide a departure warning to the driver.
