And the warning information can remind the following vehicle of the risk, so that the following vehicle can give feedback in time to eliminate the risk, thereby improving the safety of vehicle driving.

[0035] In some embodiments, as shown in FIG. 4 , a vehicle interaction method based on a tailgate is provided, the method involves a front vehicle and a rear vehicle, the front vehicle and the rear vehicle are relative concepts, the rear vehicle is a vehicle traveling behind the front vehicle, and the front vehicle is a vehicle traveling in front of the rear vehicle, the method can be executed by a control device 102 in the front vehicle, such as a vehicle 100, and includes the following steps 402 to 404. Among them:

[0036] Step 402, obtaining vehicle interaction information, where the vehicle interaction information is warning information or interaction information provided by a user in the preceding vehicle, and the warning information is information generated when there is a risk between the preceding vehicle and the following vehicle, or information generated when the driving condition of the preceding vehicle changes.

[0037] The following vehicle refers to the vehicle behind the front vehicle. The interactive information may be any information provided by the user. The user in the front vehicle may be the driver or passenger of the front vehicle. The warning information may include at least one of text, picture or video. The picture or video in the warning information is used to assist in strengthening the meaning of the text in the warning information, so that the following vehicle can understand the meaning of the text in the warning information more intuitively, easily and quickly.

[0038] Interactive information can be any information provided by the user, and the interactive information can include at least one of text, pictures or videos. Pictures can be dynamic pictures or static pictures. For example, interactive information can be information used to express the personality or mood of the user in the front car, can be information describing the personal image of the user in the front car, or can be information describing the posture and habits of the driver in the front car. For example, the interactive information is "Newbie on the road, please take care" or "Old driver, please pay attention", etc., to remind the rear car to pay attention to the driving relationship with the front car. Thus, interactive information can realize the function of personalized display of users. Through the tailgate display device, customized text or video can be displayed to highlight the personality of the owner, and at the same time, it can relieve the driving fatigue of the rear car from a visual perspective, increasing the driving experience and driving pleasure. Interactive information can also convey friendly greetings.

[0039] The interactive information can also be the personal profile or personal contact information of the person in the car, i.e. the user, or information expressing the intention to make friends. For example, during a trip, the person in the car can display interactive information on the tailgate display device to invite vehicles on the same itinerary. The interactive information can include the destination information and personal contact information of the front car, and can reflect the intention to invite vehicles on the same itinerary. Therefore, if there is a rear car on the same itinerary and willing to travel together, the person in the front car can be contacted through the personal contact information in the displayed interactive information to form a temporary execution team. Therefore, the interactive information can realize the function of making friends.

[0040] In some embodiments, the sound collection device in the front vehicle can collect the user's voice, and the user's voice is, for example, "Please display the tailgate display screen for new drivers on the road, please be careful" or "Please display the tailgate display screen for elderly drivers, please pay attention", etc. The sound collection device is, for example, a car microphone. The sound collection device can transmit the user's voice to the control device, and the control device can convert the user's voice into text to obtain the interactive information provided by the user.

[0041] In some embodiments, the mobile terminal can display an information editing page corresponding to the tailgate display device, and the information editing page can obtain interactive information input by the user. The mobile terminal responds to the information display operation triggered on the information editing page, and sends an information display request carrying the interactive information input by the user to the control device. The control device responds to the information display request and displays the interactive information on the tailgate display device.

[0042] In some embodiments, the display device in the front vehicle can display the information editing page corresponding to the tailgate display screen. When the controller detects the information display operation triggered on the information editing page, it obtains the interactive information input by the user to the information editing page and displays the interactive information on the tailgate display device. The display device in the front vehicle may not be the central control screen or the entertainment screen.

[0043] As shown in FIG5 , a schematic diagram for obtaining interactive information and displaying interactive information is provided. Specifically, the user (personnel) in the front vehicle can select or input the data to be displayed through the central control screen or the entertainment screen, can wake up the control device through the microphone, collect the voice commands issued by the user, and can also project the data to be displayed to the control device through the mobile terminal. The mobile terminal can be connected to the control device through a wireless connection method, and the wireless connection method can be but not limited to WiFi or Bluetooth. The control device can parse the voice command or input data to obtain the projection data to be displayed on the tailgate display screen, and transmit the projection data to the tailgate display screen for display. The control device can collect the display data of the tailgate display screen and synchronously feed it back to the central control screen or the entertainment screen for display, so as to realize the display control closed loop of the tailgate display screen.

[0044] In some embodiments, the control device may obtain data collected by at least one sensor in the front vehicle, perform risk analysis on the information collected by the at least one sensor, obtain risk analysis results, and generate warning information when the risk analysis results indicate that there is a risk for the front and rear vehicles. For example, since there is a risk if the distance between the front and rear vehicles is too small, when the risk analysis results indicate that the distance between the rear vehicle and the front vehicle is less than a distance threshold, a warning message is generated, such as "pay attention to the following distance". The distance threshold can be set as needed.

[0045] In some embodiments, when the preceding vehicle has a driving state change behavior, a warning message corresponding to the driving state change behavior is generated. The driving state change behavior may be, but is not limited to, a behavior that changes the original driving state, such as braking, changing lanes, or accelerating. The driving state change behavior may be detected by a sensor in the preceding vehicle, and the sensor may transmit a signal corresponding to the driving state change behavior to the controller.

[0046] In some embodiments, when the leading vehicle changes its driving status, for example, after the controller receives a signal corresponding to the driving status change, the control device collects driving data of the leading vehicle, determines the driving status of the leading vehicle based on the driving data, and displays the driving status of the leading vehicle to the trailing vehicle through the tailgate display device. The driving status may be but is not limited to braking, changing lanes, or accelerating, for example, "Please note that the leading vehicle is braking", "The leading vehicle is changing lanes to the left / right, please pay attention", or "The leading vehicle is speeding up, please pay attention" may be displayed on the tailgate display device.

[0047] As shown in FIG6 , a schematic diagram for generating and displaying warning information is provided. The sensor module in the front vehicle detects the driving data of the rear vehicle, and the driving data includes but is not limited to the distance between the rear vehicle and the front vehicle, the speed of the rear vehicle, or the steering data of the rear vehicle. The control device in the front vehicle analyzes the sensor data, i.e., the driving data detected by the sensor module, and determines whether there is a driving risk between the rear vehicle and the front vehicle. If there is a risk, the corresponding warning information is output to the tailgate display device. The control device in the front vehicle can collect the driving intention data of the front vehicle, and the driving intention data includes but is not limited to data related to steering, braking, or acceleration behaviors. According to the driving intention data, the driving intention of the front vehicle, such as steering, braking, or acceleration, can be determined, and the driving intention can be converted into warning information, such as generating warning information corresponding to the driving state change behavior. The control device can display the warning information on the tailgate display device, and can simultaneously display the warning information on the central control screen.

[0048] Step 404 , displaying the vehicle interaction information on the tailgate display device of the leading vehicle, so as to interact with the following vehicle through the vehicle interaction information.

[0049] The tailgate display device is installed on the tailgate of the preceding vehicle. The size of the display area of ​​the tailgate display device can be selected as required. The display area is the area where the content is displayed. In order to ensure the display effect, the width of the display area is greater than or equal to the width threshold, and the length is greater than or equal to the length threshold. The width threshold and the length threshold can be set as required. For example, the width threshold is 120 mm (millimeters) and the length threshold is 500 mm. In order to clearly display information under various light conditions, the tailgate display device can use a high-brightness, high-resolution LCD display, and of course other types of display screens can also be used.

[0050] In some embodiments, the vehicle interaction information may include at least one of text, pictures, or videos. When the vehicle interaction information includes at least two types of information, the control device may determine the sub-display area corresponding to each type of information in the vehicle interaction information from the display area of ​​the tailgate display device. The sub-display area is a part of the display area, and each type of information in the vehicle interaction information is displayed in the corresponding sub-display area. For example, if the vehicle interaction information includes text and pictures, the text may be displayed in one sub-display area, and the picture may be displayed in another sub-display area.

[0051] In some embodiments, when the vehicle interaction information contains only one type of information, the control device may determine the area for displaying the vehicle interaction information from the display area based on the vehicle interaction information. For example, when the vehicle interaction information contains only text, the control device may determine the entire display area as the area for displaying the vehicle interaction information, and display the vehicle interaction information in the entire display area. For vehicle interaction information in the form of pictures or videos, the vehicle interaction information may be proportionally enlarged or reduced according to the aspect ratio of the display area to fit the length or width of the display area.

[0052] In some embodiments, the control device may display the vehicle interaction information on the tailgate display device according to a preset display style. The preset display style may include at least one of a text display style, a picture display style, or a video display style. The preset display style may be set as needed. For example, the text display style may be: single-row horizontal display and the text size is greater than or equal to a size threshold. The size threshold is, for example, the size of the license plate text. The size of the license plate text is, for example, a character width of 45 mm, a character height of 90 mm, a font stroke width of 10 mm, and a character spacing of 12 mm. Of course, the size threshold may also be other set sizes.

[0053] In some embodiments, if the size of the text in the vehicle interaction information is set to a size threshold and the text in the vehicle interaction information cannot fill the area determined for displaying the text, the control device can adaptively adjust the size of the text in the vehicle interaction information so that the text in the vehicle interaction information fills the area for displaying the text.

[0054] In some embodiments, when the number of characters in the vehicle interaction information is greater than the number threshold, if the size of the characters in the vehicle interaction information is set to the size threshold, and the area for displaying the characters cannot display all the characters in the vehicle interaction information at the same time, the control device can scroll and cyclically display the characters in the vehicle interaction information on the area for displaying the characters. The number threshold can be determined according to actual conditions.

[0055] In some embodiments, while the tailgate display device displays the vehicle interaction information, the control device can simultaneously display the vehicle interaction information on the display device in the front vehicle. For example, while the tailgate display device displays the warning information, the control device can simultaneously display the warning information on the display device in the vehicle. Thus, the occupants can be informed of the warning information in a timely manner so that they can take actions to eliminate the risk in a timely manner.

[0056] In some embodiments, when the warning information is displayed on the tailgate display device, the warning information may be displayed in the form of red characters on a white background, so as to enhance the warning effect by means of the "prohibition or warning" effect expressed by the red color.

[0057] In the above-mentioned tailgate-based vehicle interaction method, vehicle interaction information is obtained and displayed on the tailgate display device of the front vehicle so as to interact with the rear vehicle through the vehicle interaction information. Since the vehicle interaction information is warning information or interaction information provided by the user in the front vehicle, the warning information is information generated when there is a risk between the front vehicle and the rear vehicle, or is information generated when the driving condition of the front vehicle changes, the information for interaction with the rear vehicle can be broadened through the tailgate display device, which helps the front vehicle and the rear vehicle to exchange richer information, thereby helping to improve the driving safety of the front vehicle and the rear vehicle.

[0058] In some embodiments, the method further includes: when the leading vehicle changes its driving direction, generating warning information corresponding to the driving direction change behavior; wherein the warning information includes a driving direction change warning word and a driving direction change pattern corresponding to the driving direction change behavior.

[0059] Among them, the driving direction change behavior can be but is not limited to the behavior of changing lanes or turning. The driving direction change warning is a sentence that expresses how the driving direction is changed, and the driving direction change pattern is a pattern that expresses how the driving direction is changed. For example, in the case where the driving direction change behavior is changing lanes to the left / turning to the left, the driving direction change warning can be "the vehicle in front is changing lanes to the left / turning to the left", and the driving direction change pattern can be a horizontal left arrow pattern; for another example, in the case where the driving direction change behavior is changing lanes to the right / turning to the right, the driving direction change warning can be "the vehicle in front is changing lanes to the right / turning to the right", and the driving direction change pattern can be a horizontal right arrow pattern.

[0060] In this embodiment, the driving direction change warning words and the driving direction change pattern are displayed on the tailgate display device of the front vehicle, so that the driving direction change pattern can assist in strengthening the meaning of the driving direction change warning words, which helps the following vehicles to understand the meaning of the driving direction change warning words more intuitively, easily and quickly.

[0061] In some embodiments, the tailgate display device includes a key display area and an auxiliary display area, and the vehicle interaction information is warning information; the vehicle interaction information is displayed on the tailgate display device of the preceding vehicle, including: displaying a driving direction change warning message in the key display area, and displaying a driving direction change pattern in the auxiliary display area.

[0062] The key display area and the auxiliary display area are part of the display area of ​​the tailgate display device. The key display area can be located at the center of the display area, and the area of ​​the key display area is larger than that of the auxiliary display area. There can be one or at least two auxiliary display areas in the display area.

[0063] In some embodiments, the control device may flash or statically display a warning message of a driving direction change in a key display area. The control device may flash or statically display a driving direction change pattern in an auxiliary display area.

[0064] In this embodiment, the driving direction change warning and the driving direction change pattern are displayed in different areas, so that the driving direction change warning is more eye-catching, and the driving direction change pattern can provide an effect of assisting understanding of the driving direction change warning.

[0065] In some embodiments, the tailgate display device includes at least two auxiliary display areas, in which a driving direction change pattern is displayed, including: in a target auxiliary display area among the at least two auxiliary display areas, the driving direction change pattern is displayed; wherein the target auxiliary display area is an auxiliary display area of ​​the at least two auxiliary display areas, close to the turn signal corresponding to the driving direction change behavior.

[0066] Among them, the driving direction change behavior corresponds to the turn signal. For example, if the driving direction change behavior is changing lanes to the left / turning left, the turn signal corresponding to the driving direction change behavior is the left turn signal; if the driving direction change behavior is changing lanes to the right / turning right, the turn signal corresponding to the driving direction change behavior is the right turn signal.

[0067] In some embodiments, the control device can divide the display area in the tailgate display device into three areas from left to right, as shown in FIG7 , the three areas are area 1, area 2 and area 3, and the aspect ratio of each area can be set as needed, for example, the aspect ratio is 16:9. Area 2 is the key display area, and area 1 and area 3 can be auxiliary display areas. The area of ​​area 1 and area 3 can be the same or different.

[0068] In this embodiment, a driving direction change pattern is displayed in an auxiliary display area near the turn signal corresponding to the driving direction change behavior. On the one hand, when the driver forgets to turn on the turn signal, the driving direction change pattern can serve as a turn signal. On the other hand, when the driver turns on the turn signal, the driving direction change pattern can have a combined display effect with the turn signal, which helps to enhance the warning effect and improve vehicle driving safety.

[0069] In some embodiments, the vehicle interaction information is warning information, and the vehicle interaction information is displayed on the tailgate display device of the preceding vehicle, including: when the interaction information provided by the user in the preceding vehicle is displayed on the tailgate display device, the tailgate display device is switched from displaying the interaction information to displaying the warning information; the method also includes: when the factor causing the warning information has been eliminated and the user has not revoked the interaction information, the tailgate display device is restored from displaying the warning information to displaying the interaction information.

[0070] In some embodiments, when interaction information is displayed on the tailgate display device, if the control device receives a cancel display instruction for the displayed interaction information, the control device cancels the display of the interaction information on the tailgate display device.

[0071] In some embodiments, the warning information is generated when there is a risk between the front vehicle and the rear vehicle. When the warning information is displayed on the tailgate display device, if the control device determines that the risk corresponding to the warning information has been eliminated, the warning information is cancelled on the tailgate display device.

[0072] In some embodiments, the warning information is information generated when the driving condition of the leading vehicle changes. When the warning information is displayed on the tailgate display device, if the control device determines that the driving condition of the leading vehicle is in a stable state, the warning information is cancelled from the tailgate display device.

[0073] In some embodiments, when the tailgate display device has displayed a warning message, when the control device receives the interactive information provided by the user, the control device may store the interactive information, and then display the interactive information after canceling the display of the warning message. The control device may also output a delayed display prompt message, and the delayed display prompt message is used to remind the user to display the provided interactive information after the warning message disappears. The control device may output the delayed display prompt message through voice, or may display the delayed display prompt message on the display device in the front vehicle.

[0074] In some embodiments, when a warning message is displayed on the tailgate display device, when the control device receives interactive information provided by the user, the control device can use voice or the output of the display device in the front vehicle to refuse to display the prompt message. The refusal to display the prompt message is used to remind the user to wait for the warning message to disappear before triggering the operation of displaying the interactive information.

[0075] In this embodiment, when the interactive information provided by the user in the preceding vehicle is displayed on the tailgate display device, the tailgate display device is switched from displaying the interactive information to displaying the warning information, so that the warning information can be displayed preferentially, which helps to give a warning to the following vehicle in a timely manner. When the factor causing the warning information has been eliminated and the user has not revoked the interactive information, the tailgate display device is restored from displaying the warning information to displaying the interactive information, so that the interactive information can be restored in a timely manner after the warning is eliminated.

[0076] In some embodiments, the interaction information is feedback information provided by a user in a leading vehicle, and the method further includes: when the following vehicle has a behavior of changing the driving state, outputting reminder information for prompting a user to give feedback on the behavior; obtaining vehicle interaction information, including: obtaining feedback information provided by a user in the leading vehicle regarding the behavior, the feedback information being information suggesting or not suggesting the execution of the behavior.

[0077] The behavior of changing the driving state is the behavior of changing the driving state. The reminder information is used to remind the front vehicle that the rear vehicle intends to change the driving state, and to remind the front vehicle to give feedback on the behavior of the rear vehicle. If the behavior of changing the driving state is the behavior of changing lanes to overtake, the reminder information can be, for example, "The rear vehicle intends to change lanes to overtake, please confirm whether it is possible to change lanes to overtake."

[0078] The driver of the vehicle ahead can give feedback through the microphone, such as "the lane ahead is merging, overtaking is not recommended" or "please overtake as soon as possible, pay attention to safety".

[0079] In some embodiments, the control device can monitor and analyze the driving data of the rear vehicle through the sensor module, and output reminder information through the in-car voice system. The control device can also display reminder information to the driver of the front vehicle through the central control screen. After the control device obtains the feedback information, it can be displayed on the tailgate display device. For example, when the sensor module in the front vehicle detects that the rear vehicle has the intention to change lanes and overtake, the in-car voice system or the central control screen can be used to remind the driver of the vehicle and request confirmation. The driver of the vehicle can give corresponding feedback through the microphone, and it will be displayed in text form on the tailgate display at the same time, expressing the feedback of the driver of the vehicle to the overtaking behavior of the rear vehicle to the rear vehicle.

[0080] In this embodiment, the driving intention of the rear vehicle (such as overtaking, following, etc.) can be fed back to the driver through reminder information, so that the driver can slow down and give way in advance or warn the rear vehicle through the tailgate display device, pay attention to safe driving, thereby improving driving safety. Feedback information on the behavior of the rear vehicle is displayed on the tailgate display device of the front vehicle, so that the front vehicle can provide guidance and suggestions to the rear vehicle through the feedback information, which helps the rear vehicle to drive more safely.

[0081] In some embodiments, the interactive information is vehicle driving information provided by a user in the front vehicle, and the vehicle driving information is used to reflect the driving status or driving intention of the front vehicle; the method also includes: after the vehicle driving information is continuously displayed for a preset period of time, if the rear vehicle does not change the driving status according to the vehicle driving information or there is a risk between the front vehicle and the rear vehicle, then a prompt message is output to remind the front vehicle to perform a response behavior, and the response behavior is a behavior used to prevent or eliminate risks.

[0082] The vehicle driving information can reflect the current driving status of the front vehicle, for example, the vehicle driving information can be "There is a child / pregnant woman in the car, driving slowly, please pay attention", "I am in an emergency, requesting to cut in line and change lanes to the right", etc., to remind the following vehicle to pay attention to the driving status or intention of the front vehicle. The preset duration can be set as needed, for example, it can be 3s (seconds) or 5s, etc. The response behavior can be, but is not limited to, honking the horn or behavior used to change the driving status of the front vehicle.

[0083] In some embodiments, the control device may output prompt information through the vehicle audio. Alternatively, the control device may display prompt information on the central control screen in a pop-up window or other manner. For example, although the front vehicle displays the vehicle driving information to the rear vehicle, the rear vehicle may not notice the vehicle driving information, and thus the rear vehicle may not notice the driving intention of the front vehicle. When the prompt information exceeds 3 seconds, if the rear vehicle still does not give relevant feedback or the front and rear vehicles have already formed a risk state, the control device may remind the driver of the front vehicle to honk the horn to remind the rear vehicle or change the driving state of the front vehicle through the vehicle audio, pop-up window on the central control display, etc., to eliminate the safety risk state with the rear vehicle.

[0084] In this embodiment, if the rear vehicle does not change its driving state according to the vehicle driving information or there is a risk between the front vehicle and the rear vehicle, a prompt message is output to remind the front vehicle to perform a response action. In this way, the risk between the rear vehicle and the rear vehicle can be eliminated in time without the rear vehicle noticing the information displayed on the tailgate display device of the front vehicle, thereby improving the driving safety of the vehicle.

[0085] The vehicle interaction method based on the tailgate provided in the present application uses the tailgate display device as an interactive window to interact with the following vehicle for information and to communicate driving intentions, thereby improving the intelligence level of the vehicle.
