Abstract

The invention includes a vehicle body portion, a plurality of photographing portions, a plurality of vehicle body display portions, a plurality of object detection portions, and a control portion. Each photographing unit captures images from the car body in different directions, and when any object detection unit detects the distance of a vehicle adjacent to the car body, it is compared by the control unit and is smaller than its built-in warning threshold. When the value is reached, the control unit controls the car body display unit corresponding to the position of the vehicle, and displays the corresponding image to achieve the same effect, so that the driver on the vehicle can see through the car body and understand the road conditions behind it. Therefore, this case has the advantages of being able to see road conditions on the other side of a large vehicle, and only starting the display section to save energy and power.

Description

Vehicle with body display

The present invention relates to a vehicle with a vehicle body display portion, and more particularly to a vehicle with a vehicle body display portion that can also see road conditions on the other side of a large vehicle and enter the distance to activate the display portion to save energy and power.

The traditional vehicle safety device has a reverse development technology in the early days, which allows the driver of the vehicle to see the image of the rear of the vehicle when reversing, so as not to hit the rear vehicle, pedestrian or object.

Later, there was a full-vehicle surround view system that could display the entire 360-degree image of the front and back of the vehicle in all directions near the driver's seat in the car for the driver of the vehicle to see.

However, in real life, some traffic accidents often occur because the large vehicle itself is an obstacle to sight. Driving on the sides of the large vehicle and adjacent vehicles are misjudged by the large vehicle blocking the line of sight, leading to accidents.

For example, as shown in Figures 11 and 12, there are three lanes on a highway, the central lane is a large passenger bus 91, and there are small cars on the left and right sides of the large passenger bus 91, which are referred to as A 92A. And the second car 92B, at this time the left car A 92A will not see the right car B 92B. Similarly, the right car 92B will not see the left car A 92A. In this case, the A car 92A and the B car 92B both want to overtake (beyond the bus 91) and cut into the central lane, then the A car 92A and the B car 921B are likely to collide unexpectedly, resulting Car accident accident.

Therefore, if the body of the bus 91 in the central lane can provide more information to the neighboring cars on both sides (that is, the first car 92A and the second car 92B), the above-mentioned accident can be avoided.

In view of this, it is necessary to develop technologies that can solve the above-mentioned conventional disadvantages.

An object of the present invention is to provide a vehicle having a vehicle body display portion, which has the advantages of being able to see the road conditions on the other side of a large vehicle, and starting the display portion to save energy and save power. In particular, the problem to be solved by the present invention is that the body of a conventional large vehicle (including a bus and a container truck) cannot provide more information to adjacent vehicles on both sides.

The technical means for solving the above problems is to provide a vehicle having a vehicle body display portion, which includes: a vehicle body portion having a left side surface, a right side surface, a rear surface, and a front surface; a plurality of photographing units, each provided separately On the left surface and the right surface, respectively, for capturing a left image and a right image; at least two vehicle body display sections are respectively provided on the left surface and the right surface, and are respectively used to display the The right image and the left image; a plurality of object detection sections are respectively disposed on the left surface and the right surface, and are respectively used to detect the distance of an adjacent object, and are respectively defined as a first distance value and A second distance value; a control unit electrically connecting the plurality of photographing units, the at least two vehicle body display units, and the plurality of object detection units, and configured to read the first distance value and the second distance value; The control unit corresponds to the first distance value and the second distance value, and respectively includes a first warning threshold value and a second warning threshold value; thereby, when the first distance value is smaller than the first warning value, Threshold The vehicle body display section located on the left surface displays the right image; and when the second warning distance value is less than the second warning threshold value, the vehicle body display section located on the right surface is controlled to display the Left image.

Referring to FIGS. 1, 2 and 3, the present invention is a vehicle having a vehicle body display portion, which includes a vehicle body portion 10, a plurality of photographing portions 20, at least two vehicle body display portions 30, and a plurality of object detection portions. 40 和 一 控制 部 50。 40 and a control section 50.

The vehicle body 10 includes a left surface 11, a right surface 12, a rear surface 13, and a front surface 14.

The plurality of photographing units 20 are respectively disposed on the left surface 11 and the right surface 12 and are used to capture a left image 20A and a right image 20B, respectively.

The at least two vehicle body display portions 30 are respectively disposed on the left surface 11 and the right surface 12 and are used to display the right image 20B and the left image 20A, respectively.

The plurality of object detection units 40 are respectively disposed on the left surface 11 and the right surface 12 and are used to detect the distance of an adjacent object, respectively, and are defined as a first distance value L1 and a second Distance value L2.

Regarding the control section 50, the plurality of photographing sections 20, the at least two vehicle body display sections 30, and the plurality of object detection sections 40 are electrically connected to read the first distance value L1 and the second distance value L2. . The control unit 50 has a first warning threshold value LM and a second warning threshold value LN built in corresponding to the first distance value L1 and the second distance value L2, respectively.

Accordingly, when the first distance value L1 is smaller than the first warning threshold value LM, the vehicle body display portion 30 located on the left surface is controlled to display the right image 20B. When the second warning distance value L2 is smaller than the second warning threshold value LN, the vehicle body display portion 30 located on the right surface is controlled to display the left image 20A.

In practice, the vehicle having a vehicle body display section further includes a front-side photographing section 201 disposed on the front surface 13 for capturing a front image 20C.

A rear-side vehicle body display portion 301 is disposed on the rear surface 14 for displaying the front image 20C.

A rear-side object detection unit 401 is disposed on the rear surface 14 and is used to detect the distance of an adjacent object, and is defined as a third distance value L3. The control unit 50 is electrically connected to the front photographing unit 201, the rear vehicle body display unit 301, and the rear object detection unit 401, and is configured to read the third distance value L3. The control unit 50 corresponds to the third distance value L3, and a third warning threshold value LK is built in.

Therefore, when the first distance value L3 is smaller than the third warning threshold value LK, the rear vehicle body display unit 301 is controlled to display the front image 20C.

The plurality of photographing sections 20 are respectively provided at the front left, rear left, front right, and rear right of the vehicle body section 10 (see FIG. 4).

The plurality of object detection sections 40 correspond to a plurality of photographing sections 20 and are respectively disposed at the left front, left rear, right front, and right rear of the car body section 10 (the photographing section 20 and the object detection section 40 may be (Because it is distributed in the upper and lower adjacent positions, it is an overlapping position as viewed from the top in FIG. 4). It is also used to detect the distance of nearby objects to generate a corresponding distance value, and is also used by the control unit 50 for comparison and should be less than its built-in When the corresponding threshold is planted, the control unit 50 can control the corresponding vehicle body display portion, and can display the corresponding image.

For example, taking the installation mode in FIG. 4 as an example, the vehicle body display portion 30 on the right surface can be controlled, and the lower left image, the left image 20A, and the upper left image can be displayed at the same time (see FIG. 5A). . In addition, the rear-side body display section 301 located behind the body section 10 may also display the upper left image, the front image 20C, and the upper right image (see FIG. 5B). Of course, these are just examples, and images of different directions can be displayed as needed.

In addition, assuming that the vehicle body 10 is a bus, the window portion may also be designed to be covered with a film or installed with a display for displaying images.

The invention is mainly applied to the image-assisted reference for road-view obstacles caused by large vehicle bodies. The following application examples are described below:

[a] Image reference for adjacent lanes: Refer to Figures 6 and 7. When driving on the road, suppose a large vehicle is blocking the view when you encounter a lane on the right and you intend to overtake to the front of the large vehicle. When the detecting section 40 detects that the object (the vehicle to be overtaking) changes from a longer distance value L4 to the first distance value L1 (less than the first warning threshold value LM), the control section 50 compares the The first distance value L1 is smaller than the first warning threshold value LM, and the vehicle body display portion 30 located on the left surface 11 is controlled to display the right image 20B, so that a vehicle intending to overtake can be informed that a large vehicle is passing through ( That is, on the right side of the vehicle body 10), there is also a vehicle that wants to overtake, so that it can slow down, or be careful to overtake, which can reduce collision accidents.

[b] Image auxiliary reference for waiting for the start of the signal: refer to Figures 8 and 9 (implemented on buses) and 10 (implemented on container trucks). When stopping at the intersection and waiting for the lights to enter, it is assumed that The left lane is obscured by large vehicles. It is completely impossible to see if there is a yellow light or a red light coming from the left side of the intersection (a collision accident may occur). When the object detection unit 40 detects an object (wait for the start of the signal) When the second distance value L2 (less than the second warning threshold value LN) is generated, the control unit 50 controls the vehicle body display unit 30 on the right side surface 12 to display the left image 20A, and may Make the vehicles waiting for the lights to start Know that on the left side of the intersection across large vehicles, there are cars coming to grab yellow or red lights, which can delay the start and proceed carefully to reduce collisions.

The advantages and effects of the present invention are as follows:

[1] You can see the road conditions on the other side of the large vehicle. When a vehicle is located on the left side of a large vehicle, this case can show the condition of the right side of the large vehicle on the body display on the left surface. Similarly, when a vehicle is located on the right side of a large vehicle, the case can The vehicle condition on the left side of the vehicle appears on the body display on the right side surface. In other words, when a large vehicle becomes a visual obstacle next to it, the large vehicle can be "seen through" and understand the road conditions behind the obstacle, greatly improving driving safety. Therefore, the road conditions on the other side of the large vehicle can be seen.

[2] Enable the display to save energy and power only after entering the distance. In this case, an object detection section is provided on the body of the vehicle. When the vehicle is detected to enter a distance smaller than the warning threshold, the corresponding display section is activated, and the display section is normally closed. Therefore, the display section only activates the display section to save energy and power.

The above is only a detailed description of the present invention through a preferred embodiment, and any simple modifications and changes made to the embodiment will not depart from the spirit and scope of the present invention.
