The external warning section 164 may be configured by adding LED lights to the left and right side mirrors of the commercial vehicle or by additionally providing LED lights at other external points.

Hereinafter, embodiments of the present invention will be described based on the roles of the above-described components.

FIG. 2 is a view showing a commercial vehicle and a dashboard used therefor. FIG. 2A schematically shows a commercial vehicle T, and FIG. 2B shows a display unit 130 included in a meter cluster and a dashboard in a commercial vehicle.

Commercial vehicles (T) are large vehicles such as trucks and trucks, and the range of blind spots is much wider than that of ordinary vehicles.

The display unit 130 occupies a part of the space of the instrument panel and can be configured as a TFT-LCD (Thin Film Transistor-Liquid Crystal Display) screen. The display unit 130 may display not only dead zone information but also various information such as a speed, a remaining amount of gasoline, and the like.

FIG. 3 is a view illustrating a definition of a detection area according to an exemplary embodiment of the present invention and a display thereof. FIG. 3A shows the definition of the detection area, and FIG. 3B shows the information display of the display part 130 corresponding to the detection area.

The control unit 120 defines a plurality of detection regions according to any one of the position and the orientation within the commercial vehicle dead zone range.

In one embodiment of the present invention, the control unit 120 defines detection regions in the left and right dead zone ranges of commercial vehicles. A ', B', C ', D', E ', and F' are defined as a plurality of detection areas in the right blind spot .

FIG. 3B shows information on a plurality of detection areas displayed on the display unit 130. FIG. The display unit 130 is displayed in a hollow shape corresponding to each detection region, and is displayed in a step shape in which the length of the bar shape is changed according to the risk determined by the control unit 120.

The control unit 120 may consider various factors in determining the risk, but in this embodiment, the risk is determined based on the distance from the commercial vehicle T. [ When the distance is close, the risk is high, and the display unit 130 displays a long bar shape as the detection area is high in risk.

4 is a diagram illustrating an example of location information display of a relative vehicle according to an embodiment of the present invention.

4A is a view showing an actual vehicle and a relative vehicle located in a detection area, and FIG. 4B is a diagram showing information display of a detection area and positional information display of a relative vehicle located in the detection area.

The control unit 120 generates position information on which of the plurality of detection areas the relative vehicle detected by the radar unit 110 is located. Then, the display unit 130 displays the generated position information. In this case, similar to the detection area, the position information is displayed on the corresponding detection area by varying the length of the bar shape according to the risk.

Since the vehicle 1 (C1) is located in the detection area F, F is lit on the display part 130 in green. Since the vehicle 2 (C2) is located in the detection area A, A is lit in green on the display part 130. [ Since the vehicle 3 (C3) is positioned over the detection areas C 'and E', the vehicle 3 (C3) lights on the display unit 130 simultaneously at C 'and E'.

5 is a diagram illustrating an example of location information of a relative vehicle when an event occurs according to an embodiment of the present invention.

5A shows a state in which the vehicle 1 (C1) and the vehicle 2 (C2) go straight and the vehicle 3 (C3) goes straight and approaches the left. At this time, the commercial vehicle T warns the vehicle 3 (C3) via the external warning section 164. Fig. 5B shows the changed display of the position information of the vehicle 3 (C3) on the display unit 130. Fig.

The control unit 120 determines the occurrence of an event based on at least one of information detected by the radar unit 110, the steering angle sensor 140, and the direction change sensing unit 150.

The occurrence of the event refers to detection of the lateral approach of the opponent vehicle from the radar unit 110, detection of steering from the steering sensing unit 140 in the direction of approaching the opponent vehicle, ) Is detected in the direction in which the turn signal lamp approaches the opponent vehicle.

The occurrence of the event is determined by distinguishing situations requiring attention, such as a case where a commercial vehicle (T) and an opponent vehicle are close to each other due to a situation in which a commercial vehicle (T) .

In Fig. 5, the vehicle 3 (C3) is close to the commercial vehicle. The control unit 120 determines that the event is occurring because the vehicle 3 (C3) is approaching in the lateral direction, and controls the display unit 130 to change the display of the position information.

The display unit 130 may change at least one of color, position, size, brightness, and flicker indicating the position information of the opponent vehicle in the detection area. In an embodiment of the present invention, the display unit 130 changes the lighting of C 'and E' from green to red. This is to draw attention to the driver by changing the green indication to the red indication in a situation requiring more attention. Also, the driver can be warned by sound or vibration through the internal warning unit 162, and the vehicle 3 (C3) can be warned via the external warning unit 164.

6 is a view illustrating another example of position information display of a relative vehicle at the time of an event according to an embodiment of the present invention.

6A shows a state in which the vehicle 1 (C1), the vehicle 2 (C2), and the vehicle 3 (C3) go straight and the commercial vehicle T moves in the left direction. 6B shows a changed display of the position information of the vehicles 1 (C1) and 2 (C2) on the display unit 130. Fig.

When the commercial vehicle T wants to move leftward, it may steer the steering wheel or flash the turn signal light to the left. The control unit 120 controls the display unit 130 to change the display of the positional information about the vehicle 1 (C1) and the vehicle 2 (C2) located on the left side of the commercial vehicle T in this situation.

The display unit 130 displays the positional information of the vehicle 1 (C1) and the vehicle 2 (C2) in red, thereby guiding the driver to pay attention when moving to the left.

7 is a view showing an example of display of positional information of a relative vehicle according to another embodiment of the present invention.

FIG. 7A shows the detection area and the actual position of the opponent vehicle, and FIG. 7B shows the display of the detection area of the display part 130 and the position information of the opponent vehicle.

According to another embodiment of the present invention, the controller 120 defines each of the regions partitioned in a lattice form as a plurality of detection regions within a blind spot range.

The display unit 130 also displays a corresponding detection area. However, in another embodiment of the present invention, the display unit 130 also displays the commercial vehicle T together on the display unit so that more visually relatively positional information can be grasped.

The display unit 130 displays the detection area occupied by the vehicle 1 (C1), the vehicle 2 (C2), and the vehicle 3 (C3) in green.

8 is a view illustrating a broad definition of a detection area according to another embodiment of the present invention.

The square of the commercial vehicle T may exist not only in the left and right but also in the front and rear. In this case, the control unit 120 is not limited to the left and right sides, but can detect the forward and rearward detection regions to provide information on a wide range of blind spots.

9 is a view illustrating an example of a position information display and a speedometer display of an opponent vehicle when an event occurs according to another embodiment of the present invention.

9A shows that the vehicle 3 (C3) moves in the direction approaching the commercial vehicle T, and FIG. 9B shows the detection area, the display of the position information and the display of the speedometer displayed on the display unit 130. FIG.

The control unit 120 calculates the relative speed between the commercial vehicle T and the opponent vehicle when an event occurs, and determines the safe speed range and the dangerous speed range based on the relative speed. Specifically, the control unit 120 may determine a speed range in which a collision probability is calculated, a speed range in which a collision probability that is higher than a certain probability is calculated, and a speed range in which a collision probability less than a certain probability is calculated, as a safe speed range . The collision probability can be determined on the basis of the lateral relative speed and the longitudinal relative speed of the commercial vehicle T and the opponent vehicle.

In Fig. 9, the vehicle 3 (C3) is approaching toward the commercial vehicle T in the leftward direction. At this time, the position information on the vehicle 3 (C3) displayed on the display unit 130 is changed to red and displayed. A speedometer 132 is also displayed on the display unit 130 so that the safe speed range 134 is displayed in a translucent blue color and the dangerous speed range 136 is displayed in a translucent red color on the speedometer 132 in a fan shape. The speed needles are contained within the critical speed range 136.

If the driver confirms the display unit 130 and maintains the speed, the driver can judge it as dangerous and reduce the speed. The driver will notice that the speed needle moves to the safe speed range 134 if the speed is slightly reduced.

10 is a view showing an example of a position information display and a speedometer display of a relative vehicle at the time of occurrence of an event according to another embodiment of the present invention.

10A shows a situation in which the commercial vehicle T is entering or is about to enter a lane change. FIG. 10B shows a situation where the speedometer 132 displayed on the display unit 130 and the safety speed range 134 superimposed on the speedometer, &Lt; / RTI >

In FIG. 10, the commercial vehicle T is difficult to enter if the speed is not changed. When the speed is slightly increased, the commercial vehicle can secure a certain distance between the front vehicle and the rear vehicle.

In this case, it is preferable that the driver lights the turn signal lamp to the left rather than steering the steering wheel.

When the turn signal lights, the safe speed range 134 and the critical speed range 136 are determined based on the relative speed. At this time, since the lateral speed of the commercial vehicle T can not be measured, it should be set in advance. The lateral speed of the commercial vehicle T may be a value set arbitrarily. Preferably, the lateral speed of the commercial vehicle T can be set as an average value by recording the lateral speed at the time of normal running and averaging the average speed.

Of course, when the driver steers the steering wheel, the safe speed range 134 and the critical speed range 136 are determined based on the relative speed.

The display unit 130 superimposes the determined safe speed range 134 and the critical speed range 136 on the speedometer 132 so that the driver can safely enter the left lane.

11 is a flowchart illustrating a method of displaying blind zone information according to an embodiment of the present invention.

Referring to FIG. 11, in step S205, the controller 120 defines a detection area.

In step S220, the steering sensing unit 140 senses the steering of the steering wheel. The steering sensor 140 provides the sensed information to the control unit 120. [

In step S225, the direction change sensing unit 150 detects whether the turn signal lamp is blinking. The direction change sensing unit 150 provides the sensed information to the control unit 120.

In step S230, the controller 120 analyzes the information received from the radar unit 110 and generates position information on which of the plurality of detection areas the opponent vehicle is located.

In step S235, the display unit 130 displays the position information according to a command from the controller 120. [ The location information is displayed differently depending on the risk of the area where the opponent vehicle is located. The specific display method is as described above.

In step S240, the controller 120 determines whether an event has occurred. The definition of the event is as described above, and the event proceeds to step S245 when an event occurs. If the event does not occur, the process returns to step S215.

In step S245, the display unit 130 displays at least one of color, position, size, brightness, and flicker displayed by the position information.

In step S250, the control unit 120 determines the approach of the opponent vehicle in the lateral direction. Specifically, when the opponent vehicle approaches the lateral direction of the three events described above, the process proceeds to step S255. If the opponent vehicle is the other two events other than the lateral approach, the process proceeds to step S260.

In step S255, the external warning unit 164 warns the opponent vehicle using light emitting means such as LED illumination.

In step S260, the controller 120 calculates the relative speed between the commercial vehicle and the opponent vehicle.

In step S265, the controller 120 determines a safe speed range and a critical speed range based on the relative speed.

In step S270, the display unit 130 displays information corresponding to the safe speed range and the critical speed range, respectively.
