Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, and in particular to a rear-approaching vehicle early warning display method, device, equipment and storage medium. BACKGROUND

[0002] The automobile rearview mirror is a vital safety component during vehicle driving, mainly used to help the driver observe the traffic conditions behind and on the sides of the vehicle. The traditional rearview mirror is divided into an in-vehicle rearview mirror and an out-vehicle rearview mirror, which respectively provide the rear and side rear views. With the development of technology, some high-end vehicles are equipped with electronic rearview mirrors or streaming media rearview mirrors, which provide clearer views through the combination of cameras and display screens, have the functions of blind area monitoring, approaching vehicle warning, etc., and further improve the driving safety. However, whether it is a traditional rearview mirror or an electronic rearview mirror, the normal functioning of its functions depends on the clarity of the mirror surface, and once the mirror surface is obscured or blurred, its role will be greatly reduced.

[0003] In the related art, in rainy and foggy weather, the vehicle door glass and the rearview mirror surface are easy to condense water mist or get rainwater, which causes the driver to be unable to clearly see the approaching vehicle warning information or the rear vehicle dynamics on the rearview mirror. This problem is particularly evident on the traditional rearview mirror, because the water mist will directly cover the mirror surface, while the electronic rearview mirror can collect images through the camera, but the water mist on the glass will also affect the shooting effect of the camera. In addition, the approaching vehicle warning function of some vehicles depends on the indicator light or display screen on the rearview mirror, and the obstruction of the water mist may cause these warning information to be unable to be timely perceived, increasing the safety hazards when changing lanes or turning.

[0044] The present application will be further described below in conjunction with the accompanying drawings and specific embodiments. The described embodiments should not be regarded as limiting the present application, and all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0045] In the following description, "some embodiments" are related to a subset of all possible embodiments, but it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0047] The automobile rearview mirror is a critical safety component during vehicle driving, mainly used to help the driver observe the traffic conditions behind and on the side of the vehicle. The traditional rearview mirror is divided into an in-vehicle rearview mirror and an out-vehicle rearview mirror, which respectively provide the rear and side rear views. With the development of technology, some high-end vehicles are equipped with electronic rearview mirrors or streaming media rearview mirrors, which provide clearer views through the combination of cameras and display screens, have blind area monitoring, vehicle approaching warning and other functions, and further improve the driving safety. However, whether it is a traditional rearview mirror or an electronic rearview mirror, the normal functioning of its function depends on the clarity of the mirror surface, once the mirror surface is blocked or blurred, its role will be greatly reduced.

[0048] In the related art, in rainy and foggy weather, water mist is easily condensed on the surface of the door glass and the rearview mirror, or rainwater is easily attached to the surface of the door glass and the rearview mirror, so that the driver cannot clearly see the car approaching warning information or the dynamic of the rear vehicle on the rearview mirror. This problem is particularly obvious on the traditional rearview mirror, because the water mist directly covers the mirror surface, and although the electronic rearview mirror can collect images through the camera, the water mist on the glass also affects the shooting effect of the camera. In addition, the car approaching warning function of part of the vehicle depends on the indicator light or display screen on the rearview mirror, and the shielding of the water mist may cause these warning information to be unable to be timely perceived, thereby increasing the safety hazard when changing lanes or turning.

[0049] Therefore, in the embodiments of the present application, a rear car approaching warning display method, device, equipment and storage medium are provided. The present application detects an environmental visibility index value corresponding to a target vehicle. The environmental visibility index value is used to represent the visibility condition of the external environment of the target vehicle. If it is determined that the environmental visibility index value is less than or equal to a first preset threshold value, a warning display component in the target vehicle is started, and the rear car approaching state of the target vehicle is warned and displayed through the warning display component. The warning display component includes a warning display light, which is arranged on the inside rearview mirror of the target vehicle. The viewpoint position of the driver of the target vehicle is detected, and the frequency at which the driver observes the outside rearview mirror of the target vehicle is determined according to the viewpoint position. If it is determined that the frequency is greater than or equal to a second preset threshold value, prompt information is output to the driver. The prompt information is used to remind the driver that the driver can observe the rear car approaching state through the warning display component. Through the detection of the environmental visibility, the warning display light in the inside rearview mirror can be automatically started in rainy and foggy weather, so as to ensure that the driver clearly obtains the rear car approaching information and reduces the safety hazard caused by the shielding of the water mist on the outside rearview mirror. At the same time, the driver can be intelligently prompted to preferentially use the in-vehicle warning component according to the habit of the driver's line of sight, so as to improve the driving safety.

[0050] Please refer to Figure 1 , Figure 1 An implementation environment schematic diagram of a rear car approaching warning display method provided in the embodiments of the present application is shown. In the implementation environment, the main software and hardware subjects mainly include a terminal device 110 and a background server 120. The terminal device 110 and the background server 120 are in communication connection.

[0051] Specifically, the rear-coming vehicle early warning display method provided in the embodiments of the present application can be executed on the terminal device 110 side alone or based on data interaction between the terminal device 110 and the background server 120. The terminal device 110 can be a vehicle-mounted terminal, for example, a central control unit of a vehicle; the background server 120 can be a standalone physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud service, cloud database, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, CDN (Content Delivery Network), and big data and artificial intelligence platform.

[0052] The terminal device 110 and the background server 120 can establish a communication connection through a wireless network or a wired network. The wireless network or the wired network uses standard communication technology and / or protocol, and the network can be set as the Internet or any other network, for example, any combination of a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a private network or a virtual private network, but is not limited to these.

[0053] Of course, it can be understood that the implementation environment in Figure 1 is only some optional application scenarios of the rear-coming vehicle early warning display method provided in the embodiments of the present application, and the actual application is not fixed to the software and hardware environment shown in Figure 1 .

[0054] Next, in combination with the foregoing introduction of the implementation environment, a rear-coming vehicle early warning display method provided in the embodiments of the present application is introduced and described.

[0055] Please refer to Figure 2 , Figure 2 is a schematic diagram of a rear-coming vehicle early warning display method provided in the embodiments of the present application. The rear-coming vehicle early warning display method includes but is not limited to:

[0056] Step 210, detecting an environmental visibility index value corresponding to a target vehicle; wherein the environmental visibility index value is used to represent the visibility condition of the external environment of the target vehicle;

[0057] Step 220, if it is determined that the environment visibility index value is less than or equal to a first preset threshold, starting a pre-warning display component in the target vehicle, and pre-warning displaying the rear vehicle state of the target vehicle through the pre-warning display component; wherein the pre-warning display component includes a pre-warning display lamp, and the pre-warning display lamp is arranged on the interior rearview mirror of the target vehicle;

[0058] Step 230, detecting the viewpoint position of the driver of the target vehicle, and determining the frequency of the driver observing the exterior rearview mirror of the target vehicle according to the viewpoint position;

[0059] Step 240, if it is determined that the frequency is greater than or equal to a second preset threshold, outputting prompt information to the driver; wherein the prompt information is used to remind the driver that the rear vehicle state can be observed through the pre-warning display component.

[0060] In the embodiments of the present application, a pre-warning display method for rear vehicles is provided. The method can automatically start the pre-warning display lamp in the interior rearview mirror in rainy and foggy weather by detecting the environment visibility, so as to ensure that the driver can clearly obtain the rear vehicle information and reduce the safety hazards caused by the water mist blocking the exterior rearview mirror. Meanwhile, the driver can be intelligently prompted to preferentially use the pre-warning component in the vehicle according to the line of sight habit, so as to improve the driving safety.

[0061] Specifically, in the embodiments of the present application, the vehicle to which the method is applied is referred to as a target vehicle. When the method in the embodiments of the present application is executed, first, the environment visibility index value corresponding to the target vehicle is detected. The index value is used to quantify the visibility condition of the external environment of the vehicle, and specifically can be the visual clarity degree of the environment where the target vehicle is located, which is evaluated by multi-sensor data fusion and intelligent algorithm.

[0062] Exemplarily, in some embodiments, the multi-sensor data described above can specifically include but is not limited to: 1) optical sensor data, for example, the target vehicle includes high-definition cameras and infrared sensors installed around the vehicle body, which can capture environment images in real time and analyze visual interference factors such as raindrop density and fog concentration, and calculate the contrast and clarity reduction degree of the image through computer vision algorithm; meteorological sensor data, including the data detected by rain sensors, humidity sensors and temperature sensors, etc. These sensors can accurately measure the rainfall intensity on the windshield, the relative humidity in the air and the temperature difference between inside and outside the vehicle, which directly affects the possibility of glass surface fogging; active detection device data, such as millimeter wave radar and laser radar, which can detect the density of suspended particles in the air by emitting electromagnetic waves and analyzing the echo signals, so as to indirectly evaluate the visibility distance.

[0063] In some specific embodiments, the data detected by the rain sensor can be recorded as first detection data, the optical sensor and the active detection device can be recorded as the visibility sensor, and the data detected by the visibility sensor can be recorded as second detection data; then, the environmental visibility index value corresponding to the target vehicle can be determined according to the first detection data and the second detection data. Specifically, the sensor data is sent to the central processing unit, and after weighted calculation and machine learning model analysis, a standardized environmental visibility index value is output, which can be set to a range of 0-100, and the lower the value, the worse the visibility.

[0064] In the embodiments of the present application, a threshold value can be set for the environmental visibility index value, which is recorded as a first preset threshold value. After obtaining the environmental visibility index value corresponding to the target vehicle, the environmental visibility index value and the first preset threshold value are compared. If the environmental visibility index value is less than or equal to the first preset threshold value, it indicates that the current environmental visibility is poor, and the system determines that the target vehicle is in an unfavorable observation weather condition, such as rain, fog, snow or dust, etc. These conditions are extremely easy to cause water mist or water droplets to accumulate on the surface of the outside rearview mirror and the window glass of the vehicle, which seriously affects the judgment of the driver on the rear vehicle. Based on this judgment, the safety warning mechanism of the target vehicle will be triggered immediately, and the warning display component installed on the rearview mirror in the vehicle will be automatically activated. Here, the warning display component can be used to display the warning of the rear vehicle of the target vehicle, specifically, it can include a warning display lamp, which can be turned on when the target vehicle has a rear vehicle, and can adopt the flashing light mode. For example, when a rear vehicle of the target vehicle is detected, a yellow light flashing warning display can be given in the direction corresponding to the rear vehicle.

[0065] On the contrary, if the environmental visibility index value is greater than the first preset threshold value, it can be determined that the current external environment has good visibility conditions, which indicates that the outside rearview mirror and the window glass of the target vehicle are not easily affected by water mist or rain accumulation at this time, and the driver can clearly observe the rear traffic conditions through the conventional way. In this case, the warning display component will remain in standby state and will not actively trigger additional in-vehicle warning prompts to avoid unnecessary interference to the driver.

[0066] It should be noted that in the embodiments of the present application, the size of the first preset threshold value can be flexibly set according to actual needs. In some cases, the environmental visibility index value can also be corrected in real time in combination with dynamic factors such as vehicle speed, lighting conditions, etc. For example, the first preset threshold value can be appropriately reduced in low-light environments such as night or tunnel, which is not limited in the present application.

[0067] In the embodiments of the present application, after starting the pre-warning display component in the target vehicle, the facial orientation and eye movement of the driver can be monitored in real time by a visual tracking module (which can use an infrared camera or a 3D ToF sensor) installed in the cockpit, and the line-of-sight focus position of the driver can be accurately captured. The module can use computer vision algorithms to process the collected image data, first establish a three-dimensional space coordinate of the driver's head posture, and then calculate the actual projection direction of the line-of-sight through pupil positioning and corneal reflection technology, so as to determine the specific area (such as the instrument panel, the road ahead, the left and right outside rearview mirrors, etc.) currently gazed at by the driver. In this way, the frequency of the driver observing the outside rearview mirror of the target vehicle can be counted. It can be understood that in the embodiments of the present application, after starting the pre-warning display component in the target vehicle, the situation of the rear vehicle can also be determined to some extent through the pre-warning display component in the vehicle, so if the driver still repeatedly observes the outside rearview mirror of the target vehicle, it means that the driver is likely not familiar with the related function transformation and has not noticed that the pre-warning display component has been enabled.

[0068] Therefore, in the embodiments of the present application, in order to help the driver quickly establish the use habit of the new pre-warning mode, another threshold value, referred to as a second preset threshold value, can be set for the above-mentioned frequency. If it is found that the frequency is greater than or equal to the second preset threshold value, a related guidance mechanism can be started, that is, a prompt information is output to the driver to remind the driver that the rear vehicle state can be observed through the pre-warning display component. Exemplarily, in the embodiments of the present application, the driver can be reminded in one or more ways. For example, in some embodiments, a brief graphic guide can be popped up on the head-up display or the center control screen to intuitively show the specific position and identification method of the pre-warning display component in the vehicle, such as using a dynamic arrow to indicate the pre-warning display light at the edge of the inside rearview mirror; in some embodiments, the vehicle-mounted voice system will give a voice prompt in a gentle tone: "The rear vehicle information has been displayed in the inside rearview mirror area, please pay attention to check". Of course, in the embodiments of the present application, the specific presentation mode of the prompt information is not limited.

[0069] Specifically, in some embodiments, the pre-warning display light includes a first pre-warning display light and a second pre-warning display light; wherein the first pre-warning display light is arranged at the lower left of the inside rearview mirror, and the second pre-warning display light is arranged at the lower right of the inside rearview mirror.

[0070] Exemplarily, please refer to Figure 3 , Figure 3A schematic diagram of a pre-warning display assembly provided in the embodiments of the present application is shown, wherein the pre-warning display lamp includes a first pre-warning display lamp 310 and a second pre-warning display lamp 320, the first pre-warning display lamp 310 is arranged at the lower left of the inner rearview mirror, and the second pre-warning display lamp 320 is arranged at the lower right of the inner rearview mirror. The first pre-warning display lamp 310 at the lower left corresponds to the situation of a vehicle approaching from the rear left side of the vehicle, and the second pre-warning display lamp 320 at the lower right corresponds to the situation of a vehicle approaching from the rear right side of the vehicle. When the system detects that a vehicle is approaching from the left blind area, the first pre-warning display lamp 310 will light up a yellow or red light and prompt the danger level with different flashing frequencies; similarly, the second pre-warning display lamp 320 will be triggered to give a warning when a vehicle approaches from the right side. Both of the pre-warning display lamps can use high-brightness LED light sources to ensure that they can be clearly seen under various lighting conditions.

[0071] Specifically, in some embodiments, after the pre-warning display assembly in the target vehicle is started, the method further includes:

[0072] outputting notification information to the driver; the notification information is used to notify the driver that the pre-warning display assembly has been started.

[0073] In the embodiments of the present application, when the system automatically activates the pre-warning display assembly in the vehicle, a notification information can be sent to the driver. The specific implementation manner of the notification information can be realized by referring to the aforementioned prompt information, which will not be described here. In the embodiments of the present application, the notification information can adopt a non-intrusive presentation manner, which ensures that the driver's line of sight does not need to leave the front road, and also enables the driver to subconsciously perceive the switching of the pre-warning mode, so that the pre-warning mode conversion in complex road conditions does not interfere with normal driving operations.

[0074] Specifically, in some embodiments, if it is determined that the environmental visibility index value is less than or equal to a first preset threshold, the pre-warning display assembly in the target vehicle is started, including:

[0075] if it is determined that the environmental visibility index value is less than or equal to a first preset threshold, sending an inquiry information to the driver; wherein the inquiry information is used to request to start the pre-warning display assembly;

[0076] in response to the confirmation feedback of the driver to the inquiry information, starting the pre-warning display assembly in the target vehicle.

[0077] In an embodiment of the present application, when it is detected that the environmental visibility index value is less than or equal to the first preset threshold, in some cases, the warning display component will not be immediately forced to start, but an inquiry message can be sent to the driver through intelligent interaction. The inquiry message is used to request the activation of the warning display component. In some embodiments, the inquiry message can be a striking floating card that appears in the safe area of ​​the instrument panel or the central control screen, and the content includes the current environmental visibility data (such as "visibility has dropped to 50 meters, it is recommended to activate the in-vehicle warning system") and a clear "confirm / not activate" touch option; in some embodiments, the inquiry message can also be a voice message, which is not limited by this application. For the driver, after receiving the inquiry message, feedback can be provided. The feedback can be a confirmation feedback to confirm the activation of the warning display component or a rejection feedback to refuse to activate the warning display component. For example, the driver can reply to the inquiry message and say "OK, please turn it on" as a confirmation feedback of the inquiry message in voice form. After receiving the driver's confirmation feedback on the inquiry message, the warning display component in the target vehicle can be activated.

[0078] This interactive activation of the warning display cleverly transforms system warnings into a safety decision-making process in which the driver actively participates. When the system detects deteriorating visibility, the query it provides isn't just a simple request to activate the function; it's also an effective safety warning. Even if the driver chooses not to activate the warning display, it subconsciously heightens their awareness of road hazards, contributing to improved vehicle safety.

[0079] Specifically, in some embodiments, detecting the viewpoint position of the driver of the target vehicle and determining the frequency of the driver observing the exterior rearview mirror of the target vehicle according to the viewpoint position includes:

[0080] Detecting the viewpoint position of the driver of the target vehicle, and when it is determined that the viewpoint position falls within the area of ​​the exterior rearview mirror, updating the currently counted cumulative number of observations;

[0081] Querying the historical time point when the frequency was last determined;

[0082] If the time interval between the historical time point and the current time point reaches a preset period duration, the frequency is determined according to the currently counted cumulative observation times and the preset period duration, and the cumulative observation times are cleared.

[0083] In the embodiments of the present application, for the frequency detection of the driver observing the outside rearview mirror of the target vehicle, a periodic implementation strategy can be adopted. Specifically, the moving track of the line of sight of the driver can be tracked in real time, and each fixed time interval (such as every 30 seconds) is taken as an analysis period. At the end of each period, the total number of times that the line of sight of the driver falls in the area of the outside rearview mirror in the time period is counted, so as to calculate the frequency of observation per unit time. This periodic detection method can not only avoid misjudgment caused by instantaneous line of sight fluctuation, but also continuously monitor the change of the observation habit of the driver through the sliding time window. Specifically, an independent data record unit can be established for each statistical period to store complete information including start / end time stamp, observation times, calculated frequency, etc. At each moment, the current cumulative observation times are counted, and the historical time point of the last determined frequency is inquired. If the time interval between the historical time point and the current time point reaches the preset period length, the corresponding frequency can be determined according to the current cumulative observation times and the preset period length, and the cumulative observation times are cleared; if the time interval between the historical time point and the current time point does not reach the preset period length, the waiting can be continued.

[0084] In the embodiments of the present application, a rear-coming vehicle early warning display device is also provided, which comprises:

[0085] A detection unit is configured to detect an environmental visibility index value corresponding to the target vehicle, wherein the environmental visibility index value is used to represent the visibility condition of the external environment of the target vehicle.

[0086] A starting unit is configured to start a warning display component in the target vehicle if it is determined that the environmental visibility index value is less than or equal to a first preset threshold, and to perform early warning display on the rear-coming vehicle state of the target vehicle through the warning display component, wherein the warning display component comprises a warning display lamp arranged on the inside rearview mirror of the target vehicle.
