The projector of the display information projecting unit 121 may be configured to have a method of generating image information by driving a laser light source of a region corresponding to a pattern to be displayed for a plurality of laser light sources arrayed in dot form, And a method of applying a filter that transmits light only in a region correspondingly.

Preferably, the display information projecting section 121 is constructed so as to project emergency warning image information 140 in the form of a tripod.

The emergency warning image information 140 of the tripod shape is formed so as to increase the visibility by causing an illusion such as three-dimensionally erected when reaching the ground.

That is, the emergency warning image information 140 of the tripod shape includes a first portion 141a extending horizontally in a strip shape and a second portion 141b extending from a centerline of the first portion 141a across the center of the first portion 141a A second portion 141b extending along a direction of approaching the vehicle 10 toward the vehicle body 10 and gradually increasing in width as it is farther from one end of the first portion 141a and a second portion 141b extending from the other end of the first portion 141a Extends along a direction approaching the vehicle 10 in such a manner as to be coupled with the front end of the second portion 141b toward the center line crossing the center of the first portion 141a and the distance from the other end of the first portion 141a Is formed into a shape having a third portion 141c formed to gradually expand.

The triangular emergency warning image information 140 is formed such that the second portion 141b and the third portion 141c are wider as they are visually recognized when traveling from the rear to the front, The stereoscopic effect is recognized by the erroneous optical effect.

On the other hand, the display information projecting section 121 can display an arrow indicator 143 for guiding the avoidance direction to the inner area of the first to third sections 141a to 141c of the tripod-shaped emergency warning image information 140 .

Here, the arrow indicator 143 is displayed so that the direction of the arrow points to the right so that the lane change can be guided to the lane two when the stopped vehicle 10 is in the first lane. When the stopped vehicle 10 is on the lane The direction of the arrow indicates the left direction so as to induce a lane change into the roadway, and the direction of the arrow indicates the both directions when the lane is in the center of the lanes.

The arrow indicator 143 may be constructed so as to operate the laser diode responsible for the display.

The rear object detection unit 123 senses the distance and the moving speed of the rear object and provides the detection result to the display control unit 128.

The rear object detecting unit 123 includes an infrared ray transmitting unit 123a for transmitting infrared ray laser light and an infrared ray receiving unit 123b for receiving infrared ray reflected from the object.

The display control unit 128 for controlling the rear object detecting unit 123 calculates the distance by counting the time from the transmission of the infrared rays to the time of receiving the infrared rays, calculates the separation distance in the same manner as the preceding measurement period, The speed is calculated using the current separation distance, the previous separation distance, and the measurement period.

The storage unit 125 records the shape or the implementation data for the text for the supported emergency alert image information.

The display communication unit 127 provides the display control unit 128 with the signal received from the terminal communication unit 155. [

The display communication unit 127 and the terminal communication unit may be constructed so as to communicate using a known communication method such as Bluetooth.

The display control unit 128 controls the display information projecting unit 121 so that the emergency warning image information projection distance of the display information projecting unit 121 is adjusted according to the distance and the moving speed of the rear object sensed by the rear object sensing unit 123 in the emergency warning mode, (121).

For example, the display control unit 128 may cause the emergency warning image information 140 to be projected at a distance of, for example, 200 meters set as the maximum projection distance if the distance of the rear object is 200 meters or more, The emergency warning image information 140 is projected at a position shorter than the separation distance if the distance is shorter than 200 meters, and the projection position of the emergency warning image information 140 is adjusted to be closer to the vehicle 10 as the traveling speed increases, And can also be constructed to increase the adjustment speed.

Setting information on the projection distance of the emergency warning image information 140 to be applied in accordance with the distance and speed of the detected rearward object of the display control unit 128 is previously recorded in a lookup table, To adjust the projection distance.

On the other hand, the operation terminal 150 is configured to enable the user to manually set the emergency warning mode, and to set the emergency warning mode automatically under specific conditions.

The operation terminal 150 includes an operation unit 151, a sensing unit 153, a terminal communication unit 155, and a terminal control unit 157.

The operation unit 151 includes a mode setting key 152 that allows the user to set or cancel the emergency warning mode by operation and first to third portions of the triangular emergency warning image information 140 in the emergency warning mode 141a to 141c are provided with three evacuation direction setting keys 151a to 151c for setting the evacuation direction guidance so that the previously described arrow indicator 143 for guiding the evacuation direction is displayed.

The sensing unit 153 is provided in the vehicle so as to receive a signal of a sensor that detects an abnormality.

As an example, the sensing unit 153 may be constructed to receive the output signal of the tire air pressure sensor or receive the operation signal of the airbag.

The terminal communication unit 155 is controlled by the terminal control unit 157 to transmit the transmission object information to the display communication unit 127. [

The terminal control unit 157 receives the emergency warning mode setting signal from the operation unit 151 or if the signal received from the sensing unit 153 automatically meets the condition for setting the emergency warning mode, And transmits a warning mode setting signal.

The terminal control unit 157 also receives the setting signals of the avoidance direction setting keys 151a to 151c from the operation unit 151 so that the indicator signal is transmitted together with the indicator setting information.

In this case, when the display setting signal of the arrow indicator is received from the operation unit 151 through the display communication unit 127, the display control unit 128 displays an arrow indicator 143 in the direction set in the trip alert warning image information 140 And controls the display information projecting unit 121 to be displayed.

The vehicle emergency warning display device 100 is mounted on the rear surface of the display main body 110 so that the operating terminal 150 can be easily operated by the driver and operates the operating portion 151 in an emergency, The arrow indicator 143 and the tripod-shaped emergency warning image information 140 can be visually recognized by the rear driver together.

In particular, the vehicle emergency warning display device 100 adjusts the projection distance of the emergency warning image information in real time in correspondence with the distance and the traveling speed of the rear vehicle, guides the vehicle to the avoidance direction while increasing the visual recognition efficiency, It is possible to more effectively suppress the occurrence of the problem.
