Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
For the reminding information displayed by the tail lamp, text reminding is generally adopted: the word "pedestrian ahead" is generally given. The disadvantage of text reminding is that the user needs to read and understand and then decide driving behaviors according to the understanding content, which extremely affects reminding efficiency; the traffic light adopts the signal lamp, so that the driver can be reminded more intuitively, and the driver can directly judge the driving behavior of the next step according to the signal lamp. For different vehicle type display modes and different word display results, the reminding effect is common for the reminded driver, and the reminded driver can not know the essential content of the matters.
Obviously, the graphic image and the color can better utilize the common sense of transportation to remind the driver, and the reminding efficiency is better. Meanwhile, the reminding content is more pictured, so that the reminded driver can know what the reminded things are, how the movement trend is, and better driving decisions can be made. The present invention thus provides the following:
referring to fig. 1 in detail, the method for controlling the display of the tail lamp provided by the invention comprises the following steps:
Step 110: an image of an object in front of the vehicle is acquired, and the object and the moving state of the object are identified.
With the development of technology, a display function is also realized by a tail lamp of an automobile, and the tail lamp can be understood as display equipment arranged at the tail part of the automobile and can comprise a warning lamp at the tail part of the automobile. Vehicle-mounted cameras and corresponding technologies have also been developed. Hardware on the intelligent automobile comprises millimeter wave radar, cameras and the like, and can be converted into information data through detection of surrounding environment, so that a user can read or assist driving.
The vehicle-mounted camera can be used to acquire images in front of the vehicle, which can be used as data for automatic driving on the one hand and as data for reminding the following vehicles on the other hand. It is understood that the process of data processing is reduced by outputting two data results through recognition 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, images of objects on the road, images of traffic lights, and so forth.
The acquired image can be used for identifying the front object and the moving state of the object, namely the type of the object, the moving direction, the moving speed, the stationary state and the like by using a convolutional neural network and the like. Based on the method, the corresponding warning reminding can be carried out on the rear vehicle.
Step 120: detecting whether a vehicle is present behind the own vehicle, and if the vehicle is present behind the own vehicle, executing display control of the tail lamp.
The tail lamp reminding mode in the prior art does not consider the state of the vehicle behind and does not need to remind whether the vehicle exists behind. This is not necessary for new energy automobiles, and is also a waste of energy and unnecessary reminder.
The invention adopts millimeter wave radar to detect the vehicle behind the vehicle, such as detecting the moving obstacle in the dead zone of 70 meters behind the vehicle, if the moving obstacle exists, the invention characterizes that the moving vehicle behind has the reminding necessity, and can send a signal to the vehicle body control module to control the tail lamp control module to start the display control.
In one embodiment of the invention, the display content of the tail light is controlled by the display control module of the tail light. In other embodiments, the display content of the tail light may be sent to the tail light through a domain controller, a body controller, or other controller, and displayed directly by the tail light.
It should be understood that this step may be performed before step 110, that is, after detecting that there is a vehicle behind the vehicle, step 110 is performed to start identifying whether there is an object in front, if there is an object, prompting the identified content to be displayed on the taillight correspondingly, and if there is no object, prompting the user not to need to be done.
Step 130: and controlling the display area of the tail lamp to display a marking image, wherein the relative position proportion of the marking image in the display area is approximately the same as the transverse position proportion of the object and the bicycle.
The marking image in the step can be a graph or an image for marking people, animals, car bodies and the like, and reminding the rear car in a graphical mode; the graphics or images may also be given a color to indicate a reminder level, such as: the display is red when the display is relatively close to the obstacle. The said indicator image is based on the recognition type of the front object by the vehicle, if the front object is recognized as a person, the indicator image of the reminder is displayed graphically by the person, and correspondingly if the object is of another type, it is displayed graphically or graphically representing the type thereof.
The vehicle has identified the moving state of the front object, and the relative position relationship between the front object and the vehicle can be represented through the dynamic display of the marking image so as to better remind the rear vehicle. Because of the problems of different running speeds, different braking performances, uncontrollable object movement states and identification accuracy of the vehicles, the problems may exist that the display is not strictly displayed in a one-to-one manner, but in some scenes, such as stationary object states, uniform self-vehicle speed and better identification performance, the display content can be displayed in a more accurate manner. It should be understood that the substantially identical steps described herein may be interpreted as dynamic, i.e., the displayed proportions are determined to be within a certain dynamic range, without affecting the judgment of the following vehicle. Errors are allowed but are controllable.
Therefore, the rear vehicle can know the specific moving state of the front object according to the dynamic display of the marked image, and carry out psychological construction, whether the vehicle can ignore or should be in emergency danger avoidance, reduce the vehicle speed and the like. Compared with the situation that pedestrians pass in front of the prompt which is abrupt in front of the prompt which is received in a confusing mode, the prompt can be better obtained, the confusion is not caused, and the prompt mode is correspondingly milder.
According to the invention, through identifying the object in front of the vehicle and the moving state of the object, when other vehicles are arranged at the rear, corresponding indication images are displayed in the display area of the tail lamp, so that 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, the prompt of the other vehicles at the rear to adjust the driving strategy in time is realized, and the problem of driving blind areas is thoroughly solved.
The system structure 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 system is mainly used for generating the indicated marked image and then sending the marked image to the light projection system 4, and the light projection system 4 comprises an image analysis unit 4.1, an array type LED controller 4.2, an array type LED4.3 and a projection module optical-mechanical system 4.4. After the image analysis unit 4.1 analyzes the marking image, the marking image is displayed by 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 the type, the moving direction, and the moving speed of the object, and taking the type, the moving direction, and the moving speed of the object as parameters for displaying the indication image.
The data acquisition of the object can be realized by using a camera or a plurality of cameras on the vehicle, for example, a camera with a wide angle of 180 degrees is used, and the Cell dragon 888 chip is adopted to process the image. Of course, a plurality of cameras can shoot images at the same time, and the images are spliced to realize image acquisition at a larger angle. And then acquiring front images acquired by one or more cameras on the vehicle, and acquiring images of the object from the front images. Limiting the shooting range to 180 degrees can clearly judge the front situation, and avoid the situation that the road condition has an emergency, so that the warning cannot be performed.
In one embodiment, the front object is identified as a person riding the electric vehicle, the direction of movement is from left to right, and the speed of movement is 5km/h. The person riding the electric vehicle, the moving direction and the speed can be used as parameters to determine the marked image and the display mode thereof.
The invention can continuously identify the moving direction and the moving speed after the neural network model identification is carried out on the object, but the calculation mode is complex and the calculation amount is larger. However, as an implementation manner, the present invention also provides a more convenient implementation manner, which is specifically as follows:
When the object and the moving state of the object are identified, dividing the shooting view angle into a plurality of areas, and positioning the object according to the area where the object is located. For example, the front view of the camera is divided into 100 areas, and pedestrians in the view are positioned. After the vision field is partitioned, a specific partition of the vision field where the pedestrians are can be positioned.
Converting the plurality of areas into percentage signals, calculating the change of the percentage signals according to the change of the area where the object is located, and calculating the moving direction of the object; and calculating the moving speed of the object according to the changing speed of the percentage signal. For example, the visual field is divided into percentage signals, such as 10%,30%,40%, etc., the movement direction of the pedestrian is calculated according to the percentage, for example, 30% -40% is left-to-right movement, and 40% -30% is right-to-left movement; and (5) according to the percentage change speed, calculating the movement speed of the pedestrian.
In a certain period of time, pedestrians move from 100 partitions of the defined view partition, are initially located in the 50 th partition, are marked as 50%, move to the 80 th partition and are marked as 80%, the position change of the partition can be known through calculation, the vehicle is indicated to move from left to right when the percentage increases, and the moving speed can be calculated according to the percentage.
Then the taillight display is controlled to display a corresponding indicator image, such as an image of the person riding the bicycle, depending on the type of object. And then controlling the marked 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 realize an equivalent result. For example, the object is located in the position far from the center of the front head of the bicycle, and then the object is displayed on the tail lamp to be 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 moves out of the acquisition range of the camera, the tail lamp is correspondingly not displayed any more.
Of course, various indication images of pedestrians, old people, children, crowd and the like can be displayed. After the type, the moving direction and the moving speed of the object of the front vehicle are known by the rear vehicle, the rear vehicle can be reminded through the relative distance between the object and the own vehicle. The reminding mode can adopt color change or flickering of images 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 closer to the vehicle, the marking image can be made to display red, and if the object is farther from the vehicle, the marking image is green, and if the object is closer to the vehicle, the marking image is made to display yellow. The distance setting can be cooperated with the vehicle speed display, for example, the distance threshold value can be set larger when the vehicle speed is slower, and the distance threshold value is set smaller when the vehicle speed is faster, so that the reaction of a driver is facilitated.
In some embodiments, a distance between the object and the vehicle is detected, and the indication image is displayed in a blinking manner according to the distance. And the frequency of flickering of the marked image can be controlled according to the distance, and the faster the flickering is, the slower the flickering is for general reminding.
In some embodiments, the distance between the object and the vehicle is detected, the display color of the indicator image is changed according to the distance, and the indicator image is made to flash. In this embodiment, the above two modes are combined and displayed to increase the importance of the driver.
For the rear driver, the reminding can be more direct, and the collision with the front vehicle is prevented. Thus, the own vehicle can detect the distance to the rear vehicle and display it in a different manner to alert the rear vehicle.
In some embodiments, the medium-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 indication image according to the distance. If the distance between the pedestrian and the vehicle is L1 (m), the vehicle length of the vehicle is L2 (m), the distance between the vehicle and the 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), if (l1+l2+l3)/(V2-V1) <1 second, it is determined that the rear vehicle is too fast, and the pedestrian in front of the vehicle is likely to collide. The calculation may be done in an ADAS (ADVANCED DRIVING ASSISTANCE SYSTEM ) module that sends a signal to the BCM, which forwards the signal to the taillight for display. For example, the collision risk is displayed in red, the early warning is displayed in yellow, and only the reminding is displayed 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 lamp is adjusted according to the distance. In the same way, the warning can be realized through the brightness of the tail lamp, and the brightness can be set to be high, general and 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 vehicle and the vehicle behind the vehicle is detected, and the display color of the indication image is changed and the display brightness of the tail lamp is adjusted according to the distance.
In one scenario, as shown in fig. 3, the control method for the tail light display includes the following steps:
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 smaller than or equal to a preset distance;
if not, step S103 is executed to project a second light type interaction image for warning the driver of the vehicle to avoid pedestrians
If step S104 is executed, a first light-type interactive image for reminding the pedestrian in advance is projected.
In the method, not only is the function of reminding a rear vehicle provided, but also the function of projecting a front pedestrian to look ahead through a front lamp is provided, and particularly, the intelligent headlight of the vehicle can be used for projection, and the function is particularly suitable for being near zebra crossings and traffic lights.
The invention can cover the view angle in the range of 180 degrees in front of the automobile, thereby solving the FOV view angle limitation of the camera/laser radar in the prior art. In addition, through the judging condition of the added angle radar, only when the coming vehicle is detected within the specified distance of the rear, the coming vehicle is judged to be at the rear, and the tail lamp can be used for reminding at the moment, so that the problem that the tail lamp of the coming vehicle is reminded no matter whether the coming vehicle is at the rear is solved. And by adding high-speed image processing, the detected actions of the front moving object are analyzed in real time, so that the tail lamp can display the detected actions of the object synchronously. In addition, the brightness of the tail lamp is adjusted in real time by calculating the movement speed of the front moving object and the position of the vehicle and calculating the distance and the speed of the side and rear incoming vehicles, so that the problem that the brightness of the tail lamp cannot be according to the alarm priority is solved.
