[0051] It should be noted that in all embodiments of the present application, the vehicle includes a rear bucket or cargo compartment for storing articles.

[0052] Please refer to Figure 1 , Figure 1 is an implementation flowchart of a vehicle tailgate control method provided by an embodiment of the present application. In the embodiment of the present application, the execution subject of the vehicle tailgate control method is a vehicle terminal.

[0053] As Figure 1 shown, the vehicle tailgate control method provided by an embodiment of the present application can include S101-S102, which are described in detail as follows:

[0054] In S101, when a tailgate opening request of the vehicle is received, the in-vehicle pushing force borne by the tailgate of the cargo compartment of the vehicle is detected.

[0055] In actual application, when a person needs to open the tailgate of the vehicle to obtain the articles in the cargo compartment, a tailgate opening request can be sent to the vehicle terminal.

[0056] In the embodiments of the present application, the detection of the tailgate opening request by the vehicle-mounted terminal can be: detecting that a person triggers a preset operation on a vehicle key in wireless communication connection with the vehicle-mounted terminal, or detecting that a person triggers a preset operation in the vehicle. The preset operation can be determined according to actual needs, which is not limited here. For example, the preset operation can be clicking a preset control (including a first preset control and a second preset control), that is, if the vehicle-mounted terminal detects that a person clicks the first preset control on the vehicle key in wireless communication connection with the vehicle-mounted terminal, or if the vehicle-mounted terminal detects that a person clicks the second preset control in the vehicle, it is considered that the preset operation is detected, that is, it is considered that the tailgate opening request sent by the person is detected. The first preset control can be a certain key on the vehicle key, and the second preset control can be a first switch located in the cockpit for controlling the opening and closing of the tailgate, or a micro switch located at the tailgate of the vehicle for controlling the tailgate.

[0057] After detecting the tailgate opening request of the vehicle, the vehicle-mounted terminal can detect the in-vehicle thrust borne by the tailgate of the cargo compartment of the vehicle. The in-vehicle thrust is used to describe the thrust generated by the goods placed in the cargo compartment when contacting the tailgate.

[0058] In an implementation manner of the embodiments of the present application, the vehicle-mounted terminal can collect the pressure signal borne by the tailgate in real time through the pressure sensor in wireless communication connection with the vehicle-mounted terminal and located at the tailgate, and determine the in-vehicle thrust according to the pressure signal.

[0059] In some possible embodiments, when the vehicle is in a driving state, if the tailgate of the vehicle is opened at this time, the goods in the cargo compartment will fall and be lost, therefore, the vehicle-mounted terminal can specifically execute step S101 through the following steps, which are described in detail as follows:

[0060] When the tailgate opening request is received, determining the state of the vehicle.

[0061] If the vehicle is in a stationary state, detecting the in-vehicle thrust borne by the tailgate.

[0062] In the embodiments, the vehicle-mounted terminal can determine the state of the vehicle when the tailgate opening request is received.

[0063] The state of the vehicle includes but is not limited to a stationary state and a driving state.

[0064] In an implementation manner of the embodiments, the vehicle-mounted terminal can acquire the vehicle speed in real time, and determine the state of the vehicle according to the vehicle speed.

[0065] In this embodiment, when the vehicle terminal detects that the vehicle is in a stationary state, it indicates that the goods in the cargo compartment need to be unloaded at this time. Therefore, in order to avoid the goods in the cargo compartment from falling, the vehicle terminal can detect the in-vehicle thrust borne by the tailgate of the vehicle.

[0066] In an embodiment of the present application, when the vehicle terminal detects that the vehicle is not in a stationary state, it indicates that the vehicle is in a driving state at this time. Therefore, in order to avoid the goods in the cargo compartment from falling and being lost during driving of the vehicle, the vehicle terminal can reject the tailgate opening request sent by the user.

[0067] In this embodiment of the present application, after the vehicle terminal obtains the in-vehicle thrust in the cargo compartment, it can compare the in-vehicle thrust with a first threshold value. The first threshold value can be set according to actual needs, which is not limited here.

[0068] In an embodiment of the present application, when the vehicle terminal detects that the in-vehicle thrust is less than or equal to the first threshold value, it can execute step S102.

[0069] In an embodiment of the present application, when the vehicle terminal detects that the in-vehicle thrust is greater than the first threshold value, it indicates that the in-vehicle thrust is too large, i.e., there are too many goods in the cargo compartment, so that when the tailgate of the vehicle is opened at this time, the goods in the cargo compartment are likely to fall, thereby causing damage to the goods. Therefore, in order to avoid the goods in the cargo compartment from falling, the vehicle terminal can reject the above-mentioned tailgate opening request and output prompt information for prompting that the in-vehicle thrust is too large, so as to remind the personnel.

[0070] In S102, when it is detected that the in-vehicle thrust is less than or equal to the first threshold value, the tailgate is opened.

[0071] In this embodiment of the present application, when the vehicle terminal detects that the in-vehicle thrust is less than or equal to the first threshold value, it indicates that the in-vehicle thrust is small, i.e., there are few goods in the cargo compartment, so that when the tailgate of the vehicle is opened at this time, the goods in the cargo compartment will not fall. Therefore, the vehicle terminal can control the tailgate of the vehicle to be opened, so as to facilitate the personnel to unload the goods in the cargo compartment.

[0072] In an embodiment of the present application, in order to further avoid the goods in the cargo compartment from falling and protect the safety of the goods, the vehicle terminal can specifically execute step S102 through S201-S204 as shown in the following table: Figure 2

[0073] In S201, when it is detected that the in-vehicle thrust is less than or equal to the first threshold value, a first image in the cargo compartment is obtained.

[0074] In an implementation manner of this embodiment, the vehicle terminal can obtain the first image in the cargo compartment in real time through a camera device which is wirelessly connected with the vehicle terminal and located in the cargo compartment.​

[0075] In S202, a placing position of each article located in the cargo compartment and in contact with the tailgate is determined according to the first image.

[0076] It should be noted that the placing position of each article is used to describe the coordinate position of each point on the surface of each article in the cargo compartment coordinate system with the center point of the cargo compartment as the origin.

[0077] In this embodiment, the vehicle terminal can determine the coordinate position of each point on the surface of each article in contact with the tailgate in the camera coordinate system according to the first image, and then perform coordinate conversion on the coordinate position of each point on the surface of each article in the camera coordinate system to obtain the coordinate position of each point on the surface of each article in the cargo compartment coordinate system, thereby determining the placing position of each article.

[0078] In S203, the opening amplitude of the tailgate is determined according to the placing position of each article.

[0079] In this embodiment, in order to avoid the articles from falling after the tailgate is opened, the vehicle terminal can determine the opening amplitude of the tailgate according to the placing position of each article.

[0080] It should be noted that since there are different opening modes of the tailgate in actual applications, the opening amplitude of the tailgate can be the opening height or the opening angle. For example, assuming that the opening mode of the tailgate is vertical rising or vertical falling, the opening amplitude of the tailgate can be the opening height.

[0081] In an embodiment of the present application, in order to improve the determination accuracy of the opening amplitude of the tailgate, the vehicle terminal can specifically determine the opening amplitude of the tailgate according to the following steps, which are described as follows:

[0082] The contact position of each article with the tailgate is determined according to the placing position of each article.

[0083] The opening amplitude of the tailgate is determined according to the placing position of each article and the contact position of each article with the tailgate.

[0084] In this embodiment, after determining the placing position of each article, the vehicle terminal can determine the contact position of each article with the tailgate.

[0085] In actual application, when the goods in the cargo compartment are placed randomly and the goods are located in the middle of the cargo compartment and partially overlap with each other, the goods are partially in a suspended state, and the goods are easy to fall when the tailboard is fully opened. Therefore, the vehicle-mounted terminal can determine the opening range of the tailboard according to the placement position of each good and the contact position of each good with the tailboard.

[0086] Specifically, the vehicle-mounted terminal can determine whether each good is partially in a suspended state according to the placement position of each good. When it is detected that a good is partially in a suspended state, the opening range of the tailboard can be determined according to the contact position of the good with the tailboard.

[0087] It should be noted that when it is detected that a good is not in a suspended state, the opening range of the tailboard can be determined as 100%.

[0088] In another embodiment of the present application, in order to further improve the accuracy of the determination of the opening range of the tailboard, the vehicle-mounted terminal can also determine the opening range of the tailboard according to the following steps, which are described as follows:

[0089] determine the shape of each good according to the first image;

[0090] determine the range according to the placement position and the shape.

[0091] In actual application, since the goods with ring-shaped structure such as spherical goods and oval goods are easy to roll, in the present embodiment, the vehicle-mounted terminal needs to determine the shape of each good in contact with the tailboard in the cargo compartment according to the obtained first image, in order to determine whether each good will roll.

[0092] Then, the vehicle-mounted terminal can determine the opening range of the tailboard according to the placement position and the shape of each good.

[0093] In some possible embodiments, the vehicle-mounted terminal can determine the opening range of the tailboard according to the height in the placement position of each good and the shape of the good. For example, when a good is the above-mentioned good with ring-shaped structure, the higher the height of the good is, the smaller the opening range of the tailboard is, so as to avoid the good from falling.

[0094] In S204, the tailboard is controlled to be opened to the range.

[0095] In the present embodiment, after determining the opening range of the tailboard, the vehicle-mounted terminal can control the tailboard to be opened to the range, so that the goods in contact with the tailboard will not fall when the tailboard is opened.

[0096] According to the method provided in steps S201-S204, the opening range of the tail plate can be flexibly determined, thereby improving the flexibility of opening the tail plate.

[0097] In an embodiment of the present application, in combination with S203, since the opening range of the tail plate is determined according to the placement position and shape of each article, in this embodiment, the vehicle-mounted terminal can detect whether the first article with a ring-shaped structure exists in the target article located at the junction of the cargo compartment and the tail plate in real time after controlling the tail plate to open to the range.

[0098] In this embodiment, when the vehicle-mounted terminal detects that the first article with a ring-shaped structure does not exist in the target article, it indicates that the first article with a ring-shaped structure has been collected, that is, there is no article prone to falling at the junction of the cargo compartment and the tail plate of the vehicle at this time, therefore, in order to improve the unloading efficiency, the vehicle-mounted terminal can adjust the opening range of the tail plate to the maximum range, that is, fully open the tail plate, to facilitate the relevant personnel to collect the articles in the cargo compartment.

[0099] As can be seen from the above, the control method of the tail plate of the vehicle provided in the embodiments of the present application detects the vehicle interior thrust borne by the tail plate of the cargo compartment of the vehicle when receiving the opening request of the tail plate of the vehicle, and controls the tail plate to open when detecting that the vehicle interior thrust is less than or equal to the first threshold. Compared with the prior art of directly opening the tail plate when detecting that the switch for controlling the tail plate is opened, the method provided in the present application needs to detect the size of the vehicle interior thrust borne by the tail plate of the cargo compartment when receiving the opening request of the tail plate, and controls the tail plate to open when detecting that the vehicle interior thrust is less than or equal to the first threshold, that is, the articles in the cargo compartment produce less extrusion on the tail plate, that is, the articles in the cargo compartment will not fall when the tail plate is opened, therefore, the tail plate can be controlled to open at this time, thereby improving the practicability and flexibility of opening the tail plate.

[0100] Please refer to Figure 3 , Figure 3 The control method of the tail plate of the vehicle provided in another embodiment of the present application. Compared with Figure 1 In the corresponding embodiment, the present embodiment can further include S301-S303 after S101, which are described as follows:

[0101] In S301, when detecting that the vehicle interior thrust is greater than the first threshold, the second image in the cargo compartment is acquired.

[0102] In an implementation manner of the present embodiment, the vehicle-mounted terminal can acquire the second image in the cargo compartment in real time through the camera device which is wirelessly connected with the vehicle-mounted terminal and located in the cargo compartment.

[0103] In S302, the placement position of each article located in the cargo compartment and in contact with the tail plate is determined according to the second image.

[0104] It should be noted that the placement position of each article is used to describe the coordinate position of each point on the surface of each article in the cargo compartment coordinate system with the center point of the cargo compartment as the origin.

[0105] In this embodiment, the vehicle-mounted terminal can determine the coordinate position of each point on the surface of each article located in the cargo compartment and in contact with the tailgate in the camera coordinate system according to the second image, and then perform coordinate conversion on the coordinate position of each point on the surface of each article in the camera coordinate system to obtain the coordinate position of each point on the surface of each article in the cargo compartment coordinate system, thereby determining the placement position of each article.

[0106] In S303, the falling probability of each article when the tailgate is opened is determined respectively according to the placement position of each article.

[0107] In actual application, when the article in contact with the tailgate in the cargo compartment is randomly placed, and the article is located in the middle part of the cargo compartment, and the article partially overlaps with other articles, causing part of the article to be in a suspended state, so that the article has the possibility of falling when the tailgate is completely opened, therefore, in this embodiment, the vehicle-mounted terminal can determine the falling probability of each article when the tailgate is opened according to the placement position of each article.

[0108] In an embodiment of the present application, in order to improve the prediction accuracy of the falling probability of each article, the vehicle-mounted terminal can specifically determine the falling probability of each article when the tailgate is opened by the following steps, which are described in detail as follows:

[0109] According to the placement position of each article, the contact angle between each article and the tailgate is determined respectively; wherein the contact angle refers to the included angle between the contact surface of the article and the tailgate and the plane where the tailgate is located.

[0110] According to the contact angle between each article and the tailgate, the magnitude of the resultant force received by each article when the tailgate is opened is predicted respectively.

[0111] According to the magnitude of the resultant force received by each article when the tailgate is opened, the falling probability of each article when the tailgate is opened is determined respectively.

[0112] In this embodiment, since the placement position of each article is used to describe the coordinate position of each point on the surface of each article in the cargo compartment coordinate system with the center point of the cargo compartment as the origin, the vehicle-mounted terminal can determine the contact angle between each article and the tailgate according to the placement position of each article. Wherein, the contact angle refers to the included angle between the contact surface of the article and the tailgate and the plane where the tailgate is located.

[0113] In actual application, each article in the cargo compartment is subjected to gravity and friction force generated by other objects (such as other articles or cargo compartment plates), and the contact angle of each article with the tail plate is different, so the contact angle of each article with other objects is also different, and thus the gravity and friction force generated by each article are also different. Therefore, the vehicle-mounted terminal can predict the magnitude of the resultant force of each article when the tail plate is opened according to the contact angle between each article and the tail plate. The magnitude of the resultant force is used to describe the sum of the gravity and friction force generated by each article.

[0114] Based on this, the vehicle-mounted terminal can determine the falling probability of each article when the tail plate is opened according to the magnitude of the resultant force of each article when the tail plate is opened.

[0115] Specifically, the vehicle-mounted terminal can compare the magnitude of the resultant force of each article when the tail plate is opened with a third threshold value. The third threshold value can be determined according to actual needs, which is not limited herein.

[0116] In an embodiment of the present application, for each article in contact with the tail plate in the cargo compartment, the vehicle-mounted terminal can determine that the falling probability of the article is a first value when detecting that the magnitude of the resultant force of the article is greater than or equal to the third threshold value.

[0117] In another embodiment of the present application, for each article in contact with the tail plate in the cargo compartment, the vehicle-mounted terminal can determine that the falling probability of the article is a second value when detecting that the magnitude of the resultant force of the article is less than the third threshold value. The second value is less than the first value.

[0118] In this embodiment, after determining the falling probability of each article, the vehicle-mounted terminal can compare the falling probability of each article with a second threshold value, respectively. The second threshold value can be determined according to actual needs, which is not limited herein.

[0119] The vehicle-mounted terminal can perform step S304 when detecting that the falling probability of each article when the tail plate is opened is less than the second threshold value.

[0120] The vehicle-mounted terminal can perform step S305 when detecting that at least one of the falling probabilities of each article when the tail plate is opened is greater than the second threshold value.

[0121] In S304, if the falling probability of each article when the tail plate is opened is less than the second threshold value, the tail plate is opened.

[0122] In this embodiment, when the vehicle-mounted terminal detects that the falling probability of each article when the tail plate is opened is less than the second threshold value, it means that each article will not fall when the tail plate is opened, and thus the vehicle-mounted terminal can control the tail plate to be opened.

[0123] In S305, if at least one of the falling probabilities of each article when the tailgate is opened is greater than the second threshold, the tailgate opening request is rejected.

[0124] In this embodiment, when the vehicle terminal detects that at least one of the falling probabilities of each article when the tailgate is opened is greater than the second threshold, it means that some articles in the cargo compartment will fall when the tailgate is opened. Therefore, in order to avoid the articles from falling, the vehicle terminal can reject the tailgate opening request.

[0125] As can be seen from the above, the control method of the vehicle tailgate provided in this embodiment comprises the following steps: when detecting that the in-vehicle thrust is greater than the first threshold, a second image in the cargo compartment is acquired; according to the second image, the placement position of each article located in the cargo compartment and in contact with the tailgate is determined; according to the placement position of each article, the falling probability of each article when the tailgate is opened is determined respectively; if the falling probability of each article when the tailgate is opened is less than the second threshold, the tailgate is opened; if at least one of the falling probabilities of each article when the tailgate is opened is greater than the second threshold, the tailgate opening request is rejected. The method provided in this embodiment can determine whether to open the tailgate according to the falling probability of each article in the cargo compartment when the in-vehicle thrust is greater than or equal to the first threshold, i.e., when the in-vehicle thrust is too large, thereby improving the determination accuracy of whether to open the tailgate.

[0126] In an embodiment of the present application, in combination with steps S101-S102, S201-S204 and S301-S305, when the vehicle terminal receives the tailgate opening request, it can determine the state of the vehicle; and when detecting that the vehicle is in a stationary state, it detects the in-vehicle thrust borne by the tailgate of the vehicle and compares the in-vehicle thrust with the first threshold.

[0127] In this embodiment, when the vehicle terminal detects that the in-vehicle thrust is less than or equal to the first threshold, it can acquire a first image in the cargo compartment; and according to the first image, the placement position of each article located in the cargo compartment and in contact with the tailgate is determined; then, according to the placement position of each article, the opening amplitude of the tailgate can be determined, or the opening amplitude of the tailgate can be determined according to the placement position and shape of each article; finally, the vehicle terminal can control the tailgate to open to the amplitude, so as to avoid the articles in the cargo compartment from falling when the opening amplitude of the tailgate is too large.

[0128] When the in-vehicle terminal detects that the in-vehicle thrust is greater than the first threshold, the in-vehicle terminal can acquire a second image of the cargo compartment, determine, according to the second image, a placement position of each article located in the cargo compartment and in contact with the tail plate, and then determine, according to the placement position of each article, a falling probability of each article when the tail plate is opened. When the falling probability of each article when the tail plate is opened is less than the second threshold, the tail plate is controlled to be opened, thereby avoiding the articles in the cargo compartment from falling.

[0129] As can be seen from the above, the method provided in the embodiment can comprehensively consider the in-vehicle thrust, the placement position of the articles in the cargo compartment, the shape of the articles, and the falling probability of the articles to determine whether the tail plate of the vehicle is opened and the opening amplitude of the tail plate, fully consider various reasons for causing the articles in the cargo compartment to fall, and thus the articles in the cargo compartment can be prevented from falling when the tail plate of the vehicle is opened.
