Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For the tail light to display the reminding information, the text reminding is generally adopted: generally, a word of "a pedestrian passes in front" or the like is given. The text reminding has the defects that reading and understanding are needed, and then the driving behavior is decided according to the understanding content, so that the reminding efficiency is extremely influenced; just as the traffic lights adopt the signal lights, the traffic lights can more intuitively remind drivers, and the drivers can directly judge the driving behaviors of the next step according to the signal lights. For different vehicle type display modes and different word type display results, the reminding effect is common for the reminded driver, and the reminded driver can not know the essential content of the affair.
Obviously, the graphic images and the colors can better utilize the traffic general knowledge to remind the driver, and the reminding efficiency is better. Meanwhile, the reminding content is more liked, so that the reminded driver can know what the reminded object is and how the driver moves, and better driving decision can be made. The invention thus provides the following:
as shown in detail in fig. 1, the method for controlling the display of the tail light provided by the invention comprises the following steps:
step 110: the method comprises the steps of acquiring an image of an object in front of the vehicle, and identifying the object and the moving state of the object.
With the development of the technology, the display function is also realized by the automobile tail lamp, which can be understood as a display device arranged at the tail of an automobile and can comprise a warning lamp at the tail of the automobile. Vehicle-mounted cameras and corresponding technologies have also been developed. Hardware on the intelligent automobile, including millimeter wave radar, cameras and the like, can be converted into information data through detection of surrounding environment, and is used for reading or assisting driving by a user.
Therefore, the vehicle-mounted camera can be used for acquiring images in front of the vehicle, and the road images can be used as data of automatic driving on one hand and reminding contents of vehicles behind on the other hand. It can be understood that the data processing process is reduced by outputting two data results through the identification of the same data. For example, when only one wide-angle camera is used, images from the front of the vehicle are acquired, including images of the road, objects on the road, traffic lights, and so forth.
For the acquired image, the object in front and the moving state of the object, i.e. the category and moving direction of the object, moving speed, stopping state, etc. can be identified by using a convolutional neural network, etc. Based on the warning reminding method, corresponding warning reminding can be carried out on the rear vehicle.
Step 120: whether a vehicle exists behind the vehicle is detected, and if the vehicle exists behind the vehicle, the vehicle executes display control of the tail lamp.
In the prior art, a tail lamp reminding mode does not consider the state of a vehicle behind and does not remind the vehicle behind in a different way. This is unnecessary for new energy automobile, also belongs to energy waste and unnecessary warning.
The invention adopts the millimeter wave radar to detect the vehicle behind the self-vehicle, for example, a moving obstacle in a blind area of 70 meters behind the self-vehicle is detected, if the moving obstacle exists, the necessity of reminding the moving vehicle behind is represented, a signal can be sent to the vehicle body control module, and the tail lamp control module is controlled to start the display control.
In an embodiment of the invention, the display content of the tail light is controlled by the display control module of the tail light itself. In other embodiments, the display content of the tail light may be the display content sent to the tail light by the domain controller, the body controller, or other controller, and displayed directly by the tail light.
It should be understood that this step may be placed before step 110, that is, after a vehicle is detected behind the vehicle, step 110 is executed to start identifying whether there is an object in front, if there is an object, the identified content is displayed on the tail light correspondingly, and if there is no object, no warning is needed.
Step 130: and controlling a display area of the tail lamp to display a mark image, wherein the relative position proportion of the mark image in the display area is approximately the same as the transverse position proportion of the object and the self vehicle.
In the step, the marking image can be a figure or an image marked as a person, an animal, a car body and the like, and the rear car is reminded in a graphical mode; at the same time, the graphics or images may be given colors to indicate the alert level, for example: closer to the obstacle is shown in red. The marking image is determined according to the recognition type of the front object by the self-vehicle, if the front object is recognized as a person, the reminding marking image is displayed by the figure of the person, and correspondingly, if the object is of other types, the reminding marking image is also displayed as the figure or the image representing the type of the object.
The self-vehicle can identify the moving state of the front object through the dynamic display of the marking image to represent the relative position relation of the front object and the self-vehicle so as to better remind the rear vehicle. Due to the problems of different driving speeds, different braking performances, uncontrollable object motion states and recognition accuracy of vehicles, the display contents may not be strictly displayed in a one-to-one manner, but in some scenes, such as static object states, uniform speed of the vehicle and good recognition performance, the display contents can be displayed in a more accurate manner. It is to be understood that substantially the same as described in the steps may be interpreted as dynamic, i.e. the displayed scale is determined within a certain dynamic range, without affecting the judgment of the rear vehicle. Allowing for errors but with controlled errors.
Therefore, the rear vehicle can know the specific moving state of the front object according to the dynamic display of the marking image, so that the psychological construction can be carried out, and whether the danger is ignored or should be avoided urgently, the vehicle speed is reduced, and the like. Compared with the situation that pedestrians pass by in front of the received disappearing prompt, the prompt can be better reminded, confusion is avoided, and the prompt mode is correspondingly milder.
According to the invention, through identifying the object in front of the self-vehicle and the moving state of the object, and displaying the corresponding marking image in the display area of the tail lamp when other vehicles are arranged at the rear, the other vehicles at the rear can know the relative position and the moving state of the obstacle relative to the front vehicle, and particularly, the structure diagram of the tail lamp control system shown in FIG. 2 can be adopted, so that the driving strategy can be reminded to adjust other vehicles at the rear in time, and the problem of driving blind areas can be thoroughly solved.
The system configuration shown in fig. 2 includes a vehicle body control system (not shown), a perception system 2, an interactive control system 3, and a light projection system 4. The sensing system 2 comprises a sensing unit 2.1 and an information acquisition unit 2.2, and is mainly used for acquiring images and data in the images; the interactive control system 3 comprises an interactive control unit 3.1 and an image generation unit 3.2; the light projection system is mainly used for generating the marking image and then sending the marking image to the light projection system 4, and the light projection system 4 comprises an image analysis unit 4.1, an array LED controller 4.2, an array LED4.3 and a projection module optical mechanical system 4.4. After the image analyzing unit 4.1 analyzes the marking image, the marking image is displayed through the array type LED controller 4.2, the projection module optical mechanical system 4.4 and the array type LED 4.3.
Further, in the embodiment shown in fig. 1, the identifying the object and the moving state of the object in step 110 includes identifying a type, a moving direction, and a moving speed of the object, and using the type, the moving direction, and the moving speed of the object as parameters for displaying the indication image.
The data collection of the object may be implemented by using a camera or a plurality of cameras on the vehicle, for example, a 180 ° wide-angle camera is used, and the image is processed by using the cellcept 888 chip. Of course, a plurality of cameras can shoot images simultaneously, and all the images are spliced to realize image acquisition at a larger angle. Then, a front image collected by one or more cameras on the vehicle is obtained, and an image of the object is obtained from the front image. The shooting range is limited to 180 degrees, the front condition can be judged clearly, and the condition that the road condition has an emergency and the early warning cannot be performed is avoided.
In one embodiment, the front object is identified as a person riding an electric vehicle, the moving direction of the front object is from left to right, and the moving speed is 5km/h. The marking image and the display mode thereof can be determined by taking the person riding the electric vehicle, the moving direction and the speed as parameters.
The invention can continuously identify the moving direction and the moving speed after carrying out the neural network model identification on the object, but the calculation mode is more complex and the calculation amount is larger. But not as an implementation, the present invention also provides a more convenient implementation, which is as follows:
when the object and the moving state of the object are identified, a shooting view angle is divided into a plurality of areas, and the object is positioned according to the area where the object is located. For example, the front view field of the camera is divided into 100 areas, and pedestrians in the view field are positioned. After the vision field is partitioned, the specific partition of the vision field where the pedestrian is located can be positioned.
Converting the areas into percentage signals, and calculating the change of the percentage signals according to the change of the areas where the objects are located to calculate the moving direction of the objects; and calculating the moving speed of the object according to the change speed of the percentage signal. For example, the field of view is converted into percentage signals, such as 10%,30%,40%, and the like, and the moving direction of the pedestrian is calculated according to the percentage, for example, the pedestrian moves from 30% to 40% from left to right, and the pedestrian moves from 40% to 30% from right to left; and calculating the moving speed of the pedestrian according to the change speed of the percentage.
In a certain time, the pedestrian moves from 100 zones of the defined vision zone, is initially positioned in the 50 th zone, is marked as 50%, moves to the 80 th zone, is marked as 80%, the change of the zone position and the increase of the percentage mean that the vehicle moves from left to right can be known through calculation, and the moving speed can be calculated according to the percentage.
When the tail lamp is controlled to display, the corresponding marking image is displayed according to the type of the object, such as the image of the riding person. And then controlling the marking image to be dynamically displayed in the display area according to the moving state of the object. Since the moving direction and the moving speed of the object are known, the display range of the tail lamp can be calculated to achieve equivalent results. For example, if the object is located right away from the center of the head of the vehicle in front of the vehicle, the position displayed on the tail lamp is the center position of the tail lamp. If the pedestrian moves to the left, the displayed image also moves to the left. If the pedestrian shifts out the camera acquisition scope, the tail lamp is corresponding no longer showing.
Of course, various indication images of pedestrians, old people, children, people, and the like can also be displayed. After the rear vehicle is satisfied and the type, the moving direction and the moving speed of the object of the front vehicle are known, the rear vehicle can be reminded of the relative distance between the object and the self vehicle. The reminding mode can adopt color change or image flashing and the like.
In some embodiments, a distance between the object and the host vehicle is detected, and a display color of the indicator image is changed according to the distance. If the object is close to the vehicle, the marking image can be displayed in red, and if the object is far away from the vehicle, the marking image is displayed in green, and if the object is far away from the vehicle, the marking image is displayed in yellow. The distance setting can be displayed in cooperation with the vehicle speed, for example, the distance threshold can be set to be larger when the vehicle speed is slower, and the distance threshold is set to be smaller when the vehicle speed is faster, so that the driver can conveniently react.
In some embodiments, the distance between the object and the self-vehicle is detected, and the marking image is displayed in a flashing manner according to the distance. Similarly, the frequency of image flashing can be controlled according to the distance, the more urgent the flashing is, the slower the flashing is generally reminded.
In some embodiments, the distance between the object and the self-vehicle is detected, and the display color of the marking image is changed and the marking image is flickered according to the distance. In this embodiment, the display is performed in combination with the above two ways to increase the attention of the driver.
For the driver behind, remind can be more direct, prevent with the preceding car striking. Therefore, the host vehicle can detect the distance from the rear vehicle and display the distance in different modes to remind the rear vehicle.
In some embodiments, the middle-range millimeter wave radar detects a distance between the host vehicle and a vehicle behind the host vehicle, and changes a display color of the indicator image according to the distance. Assuming that the distance between a pedestrian and a vehicle is L1 (m), the vehicle length of the vehicle is L2 (m), the distance between the pedestrian and a rear vehicle is L3 (m), the moving speed of the vehicle is V1 (m/s), and the moving speed of the rear vehicle is V2 (m/s), when (L1 + L2+ L3)/(V2-V1) <1 second, it is determined that the rear vehicle is too fast and the pedestrian may hit the front. The calculation can be done in an ADAS (Advanced Driving Assistance System) module, which sends the signal to the BCM, which forwards the signal to the tail light for display. For example, if the collision risk is displayed in red, the early warning display is in yellow, and only the reminding display is in green.
In some embodiments, the distance between the vehicle and the vehicle behind the vehicle is detected, and the display brightness of the tail light is adjusted according to the distance. Similarly, the warning can be realized by the brightness of the tail lamp, and the brightness can be set to be high, normal or slightly dark; the specific brightness can be determined according to the requirement, and the brightness is obviously distinguished.
In some embodiments, the distance between the host vehicle and a vehicle behind the host vehicle is detected, the display color of the indicator image is changed according to the distance, and the display brightness of the tail light is adjusted.
In one scenario, as shown in fig. 3, the control method of the tail light display includes the steps of:
step S101: judging whether a person exists in the forward direction of the vehicle;
step S102: judging whether the distance between the person and the vehicle is less than or equal to a preset distance;
if not, step S103 is executed, a second light type interactive image for warning the driver of the vehicle to avoid the pedestrian is projected
If yes, step S104 is executed to project a first light type interactive image for reminding the pedestrian of the preceding light type.
According to the method, a function of reminding a rear vehicle and a function of projecting a pedestrian ahead through a front lamp are provided, and particularly, an intelligent headlamp of the vehicle can be used for projection, and the function is particularly suitable for being used near a zebra crossing and a traffic light.
The invention can cover the view angle within 180 degrees in front of the vehicle, thereby solving the FOV view angle limitation of the camera/laser radar in the prior art. In addition, by adding the judgment condition of the angle radar, only when the fact that a vehicle comes within a specified distance behind is detected, the fact that the vehicle comes behind is judged, and the tail lamp only reminds, so that the problem that the vehicle is reminded whether the vehicle comes behind or not is solved. And by adding high-speed image processing, the detected motion of the front moving object is analyzed in real time, so that the tail lamp can display the motion of the detected object synchronously. In addition, the problem that the brightness of the tail lamp cannot be adjusted according to the alarm priority is solved by calculating the movement speed of the moving object in front and the position of the vehicle and calculating the distance and the speed of the vehicle coming from the side rear and adjusting the brightness of the tail lamp in real time.
