Description

Technical Field

[0001] The present application relates to the field of vehicles, and more particularly, to a vehicle control method, a control device, and a vehicle in the field of vehicles. Background Art

[0002] The tailgate is the trunk of the vehicle. By opening the tailgate, you can place items in the trunk. By configuring the tailgate with an electric support rod, you can achieve intelligent control of the opening or closing of the tailgate by extending and retracting the electric support rod.

[0003] When a user opens the tailgate of a vehicle, it is usually accompanied by the behavior of taking items from the trunk of the vehicle or placing items in the trunk; therefore, how to facilitate users to take and put items and improve the user experience during vehicle use is an issue that needs to be urgently addressed. Summary of the Invention

[0004] The present application provides a vehicle control method, a control device, and a vehicle. The control method can facilitate users to take and place items, thereby improving the user experience during vehicle use.

[0005] In a first aspect, a vehicle control method is provided, the control method comprising:

[0006] If an opening instruction for the lower tailgate of the vehicle is received, detecting a target state of a trunk in the vehicle; wherein the target state of the trunk is used to indicate whether there is an item in the trunk;

[0007] determining a target height according to the target state of the trunk, the target height being used to indicate the height between the vehicle chassis and the ground;

[0008] The vehicle chassis is controlled according to the target height.

[0009] In an embodiment of the present application, if a command to open the vehicle's lower tailgate is received, the target state of the vehicle's trunk is detected; based on the target state of the trunk, the target height of the vehicle's chassis above the ground is determined; and the vehicle's chassis is controlled to rise or fall based on the target height. In this solution, the target state of the trunk is detected to determine the height of the vehicle's chassis above the ground; and the vehicle's chassis is controlled based on the target height. Therefore, based on the target state of the trunk, the user's need to open the trunk can be determined, and the vehicle's chassis can be controlled to rise or fall based on different user needs, making it easier for users to take and put items, and improving the user experience during vehicle use.

[0010] In conjunction with the first aspect, in certain implementations of the first aspect, determining the target height according to the target state of the trunk includes:

[0011] If the target state indicates that the object does not exist in the trunk, determining the target height to be a first preset height; or,

[0012] If the target state indicates that the object is not present in the trunk, the target height is determined according to the detected volume of the target object carried by the target user.

[0013] In an embodiment of the present application, since the target state indicates that there is no item in the trunk of the vehicle, it can be determined that the target user's purpose of opening the trunk is to place items in the trunk; therefore, the height of the vehicle chassis can be determined as a first preset height, or the target height can be determined based on the volume of the items carried by the user to be placed in the trunk; thereby improving the convenience of the user in placing items in the trunk of the vehicle.

[0014] In combination with the first aspect and the above implementations, in certain implementations of the first aspect, determining the target height based on the detected volume of the target item carried by the target user includes:

[0015] The target height is determined according to the volume of the target object and the height of the target user.

[0016] In an embodiment of the present application, when determining the target height of the chassis based on the target items carried by the target user, the height of the target user (i.e., the height of the target user) needs to be considered; since target users of different heights feel comfortable at different target heights when placing items in the trunk; therefore, determining the target height of the chassis based on the volume of the target item and the height of the target user can better meet the needs of target users of different heights, thereby improving the convenience of different target users when placing items in the trunk of the vehicle.

[0017] In combination with the first aspect and the above implementations, in certain implementations of the first aspect, determining the target height based on the volume of the target object and the height of the target user includes:

[0018] If the height of the target user is greater than or equal to a preset height threshold, and the volume of the target object is less than a preset volume, determining the target height as a first target height;

[0019] If the height of the target user is greater than or equal to a preset height threshold, and the volume of the target object is greater than or equal to a preset volume, determining the target height as a second target height;

[0020] Among them, the first target height is greater than the second target height; the first target height is greater than the current height, and the current height is used to represent the height between the vehicle chassis and the ground when the start instruction is detected.

[0021] In an embodiment of the present application, when the height of the target user is greater than or equal to the preset height threshold and the volume of the target item is less than the preset volume, it means that the user with taller height is carrying a target item with smaller volume, and at this time the target height is determined to be the first target height, which is greater than the current height; when the height of the target user is greater than or equal to the preset height threshold and the volume of the target item is greater than or equal to the preset volume, it means that the user with taller height is carrying a target object with larger volume, and the target height is determined to be the second target height; through the above scheme, the target height of the vehicle chassis and the ground can be determined according to the height of the target user and the volume of the target item; thereby achieving different chassis heights of the vehicle when a user with taller height places items of different volumes in the trunk, thereby improving the intelligence level of the vehicle chassis height adjustment and better meeting the needs of users.

[0022] In combination with the first aspect and the above implementations, in certain implementations of the first aspect, determining the target height based on the volume of the target object and the height of the target user includes:

[0023] If the height of the target user is less than a preset height threshold, and the volume of the target object is less than a preset volume, determining the target height to be a third target height;

[0024] If the height of the target user is less than a preset height threshold, and the volume of the target object is greater than or equal to a preset volume, determining the target height to be a fourth target height;

[0025] The third target height is greater than the fourth target height, and the fourth target height is less than the current height. The current height is used to indicate the height between the vehicle chassis and the ground when the tailgate of the vehicle is not opened.

[0026] In an embodiment of the present application, when the height of the target user is less than the preset height threshold and the volume of the target item is less than the preset volume, it means that the user with shorter height carries a target item with smaller volume; at this time, the target height is determined to be the third target height; when the height of the target user is less than the preset height threshold and the volume of the target item is greater than or equal to the preset volume, it means that the user with shorter height carries a target item with larger volume; at this time, the target height is determined to be the fourth target height; wherein the third target height is greater than the fourth target height; through the above scheme, the target height of the vehicle chassis and the ground can be determined according to the height of the target user and the volume of the target item; and when a user with shorter height places items of different volumes in the trunk, the chassis height of the vehicle is different, thereby improving the intelligence level of the vehicle chassis height adjustment and better meeting the needs of users.

[0027] In combination with the first aspect and the above implementations, in certain implementations of the first aspect, determining the target height according to the target state of the trunk includes:

[0028] If the target state indicates that the item is present in the trunk, determining the target height based on the weight of the item;

[0029] The weight is inversely proportional to the target height; the target height is less than the current height, and the current height is used to represent the height between the vehicle chassis and the ground when the tailgate of the vehicle is not opened.

[0030] In an embodiment of the present application, if the target status indicates that there are items in the trunk, the target height is determined based on the weight of the items in the trunk. The heavier the items, the lower the target height. Since when the target status indicates that there are items in the trunk, it can be determined that the main purpose of the user opening the trunk is to take out the stored items from the trunk. Therefore, the height of the chassis is determined based on the weight of the items. When the weight of the items is greater, the height of the chassis is lower, ensuring that the user can take out the stored items from the trunk more easily.

[0031] In combination with the first aspect and the above implementations, in some implementations of the first aspect, the method further includes:

[0032] If the target state indicates that the object does not exist in the trunk, the vehicle chassis is controlled to be adjusted to the current height.

[0033] In an embodiment of the present application, when items in the vehicle trunk are taken out by the user, the vehicle chassis can be controlled to return to the height when the vehicle trunk is not opened; thereby ensuring that when the user takes out items in the trunk and does not need to store items in the trunk, the chassis is controlled to return to the initial height and will not affect the normal driving of the vehicle.

[0034] In combination with the first aspect and the above implementations, in some implementations of the first aspect, the method further includes:

[0035] If an opening command for the vehicle's upper tailgate is detected, determining whether a user is detected within a preset range;

[0036] If a user is detected within a preset range, identifying the user's height;

[0037] The opening degree of the upper tailgate is determined according to the height of the target user.

[0038] In an embodiment of the present application, if an opening command for the upper tailgate in a vehicle is detected, it is determined whether a target user is detected within a preset range at the rear of the vehicle; if a target user is detected, the height of the target user is identified, and the opening degree of the upper tailgate is determined based on the height of the target user; the opening height of the upper tailgate is intelligently set to a suitable height of the target user to prevent a collision with the target user due to the upper tailgate opening height being too low; or the upper tailgate opening height being too high to make it inconvenient for the target user to touch the tailgate.

[0039] In a second aspect, a vehicle control device is provided, the control device comprising:

[0040] a detection module, configured to detect a target state of a trunk in the vehicle upon receiving an opening instruction for a lower tailgate in the vehicle; wherein the target state of the trunk is used to indicate whether there is an object in the trunk;

[0041] a determination module, configured to determine a target height according to a target state of the trunk, wherein the target height is used to indicate the height between the vehicle chassis and the ground;

[0042] A control module is used to control the vehicle chassis according to the target height.

[0043] In a third aspect, a vehicle is provided, comprising a memory and a processor, wherein the memory is used to store executable program code, and the processor is used to call and run the executable program code from the memory, so that the vehicle executes the method in the above-mentioned first aspect or any possible implementation of the first aspect.

[0044] In a fourth aspect, a computer program product is provided, comprising: a computer program code, which, when executed on a computer, enables the computer to execute the method in the first aspect or any possible implementation of the first aspect.

[0045] In a fifth aspect, a computer-readable storage medium is provided, which stores a computer program code. When the computer program code runs on a computer, the computer executes the method in the above-mentioned first aspect or any possible implementation of the first aspect.

[0057] The following will clearly and thoroughly describe the technical solutions in this application in conjunction with the accompanying drawings. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0058] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0059] In order to enhance the diversity of tailgate functions and meet the personalized needs of different users, the present application provides a vehicle tailgate that opens up and down, comprising an upper tailgate and a lower tailgate, which open up and down.

[0060] Figure 1 This is a structural schematic diagram of an upper tailgate and a lower tailgate provided in an embodiment of the present application.

[0061] For example, in Figure 1 In the structure shown, the opening and closing processes of the upper tailgate and the lower tailgate will not affect each other. Figure 1 As shown in (a) in the figure, when the tailgate of the vehicle is in a locked state, after receiving an opening command, the upper tailgate and the lower tailgate in the tailgate can be opened at the same time, or, when receiving an opening command for the upper tailgate, the upper tailgate is controlled to open and the upper tailgate is in a closed and locked state; when receiving an opening command for the lower tailgate, the lower tailgate is controlled to open and the upper tailgate is in a locked state.

[0062] like Figure 1 As shown in (b), when the tailgate of the vehicle is in the open state, if a closing command is received, the upper tailgate and the lower tailgate in the tailgate can be closed at the same time, or, when a closing command of the upper tailgate is received, the upper tailgate is controlled to be closed and the lower tailgate is in the open state; after receiving a closing command of the lower tailgate, the lower tailgate is controlled to be closed and the upper tailgate is in the open state.

[0063] Figure 2 This is a schematic diagram of the process of opening and closing a vehicle tailgate provided in an embodiment of the present application.

[0064] S201: The vehicle body domain controller receives any opening or closing instruction.

[0065] Exemplarily, when the vehicle body domain controller receives any opening or closing instruction, including an opening or closing instruction for the upper tailgate and an opening or closing instruction for the lower tailgate.

[0066] S202: The tailgate controller receives any opening or closing instruction.

[0067] Exemplarily, the tailgate controller receives any opening or closing instruction sent by the body domain controller and executes the instruction.

[0068] S203, controlling the tailgate to open or close.

[0069] S204, controlling the tailgate to open or close.

[0070] For example, when the tailgate controller receives the instruction sent by the body domain controller, the tailgate controller controls the opening or closing of the upper tailgate and the lower tailgate at the same time.

[0071] Optionally, after receiving a lower tailgate opening instruction, the lower tailgate is opened; after receiving an upper tailgate opening instruction, the upper tailgate is opened; or, after receiving a lower tailgate closing instruction, the lower tailgate is closed; after receiving an upper tailgate closing instruction, the upper tailgate is closed.

[0072] Figure 3 This is a schematic structural diagram of another upper tailgate and lower tailgate provided in an embodiment of the present application.

[0073] For example, in Figure 3 In the structure shown, the opening or closing process of the upper tailgate and the lower tailgate will affect each other. Figure 3 As shown in (a), the upper tailgate is provided with an outer lap edge and the lower tailgate is provided with an inner lap edge. When both the upper tailgate and the lower tailgate are in the locked state, the outer lap edge covers the inner lap edge (i.e. the upper tailgate covers the lower tailgate). After receiving any opening command, the lower tailgate can be controlled to open only after the upper tailgate is controlled to open; Figure 3 As shown in (b), when both the upper and lower tailgates are in the open state, upon receiving any closing command, the lower tailgate needs to be closed before the upper tailgate can be closed, so that the outer edge of the upper tailgate covers the inner edge of the lower tailgate.

[0074] Figure 4 This is a schematic diagram of another process for opening and closing a vehicle tailgate provided in an embodiment of the present application.

[0075] For example, Figure 4 (a) shows the process of opening or closing the tailgate. Figure 4 (b) in FIG. 4 shows the process of opening or closing the lower tailgate. The following describes the process of opening or closing the upper tailgate and the lower tailgate in detail.

[0076] S301, the body domain controller receives the tailgate opening / closing instruction.

[0077] Exemplarily, after receiving the opening or closing instruction of the upper tailgate, the body domain controller sends a command signal to the upper tailgate controller.

[0078] S302: The upper tailgate controller receives an upper tailgate opening instruction.

[0079] S303, controlling the tailgate to open.

[0080] For example, when the upper tailgate controller receives the upper tailgate opening instruction sent by the upper tailgate, it controls the upper tailgate to open after detecting that the environmental conditions are met (for example, there are no obstacles).

[0081] S304: The upper tailgate controller receives an upper tailgate closing instruction.

[0082] S305, detecting the status of the lower tailgate.

[0083] S306: If the lower tailgate is in the closed state, the upper tailgate is controlled to close.

[0084] For example, when the upper tailgate controller receives an upper tailgate closing command, it detects the status of the lower tailgate. When it detects that the lower tailgate is in the closed state, it controls the upper tailgate to close; ensuring that the outer edge of the upper tailgate covers the inner edge of the lower tailgate.

[0085] For example, when the lower tailgate of the vehicle is controlled to be opened or closed, steps S307 to S312 are executed:

[0086] S307, when the body domain controller receives the opening / closing instruction of the lower tailgate.

[0087] S308: The lower tailgate controller receives a lower tailgate opening instruction.

[0088] S309, detecting the status of the upper tailgate.

[0089] S310: If the upper tailgate is in the open state, control the lower tailgate to open.

[0090] For example, when the lower tailgate controller receives the lower tailgate opening command sent by the body domain controller, it needs to first detect the status of the upper tailgate. When it detects that the upper tailgate is open, it controls the lower tailgate to open; ensuring that the upper tailgate with an outer overlapping edge does not hinder the opening of the lower tailgate with an inner overlapping edge.

[0091] S311: The lower tailgate controller receives a lower tailgate closing instruction.

[0092] S312, controlling the tailgate to close.

[0093] For example, when the lower tailgate controller receives a lower tailgate closing instruction sent by the body domain controller, it can directly control the lower tailgate to close.

[0094] In response to the structure of the vehicle tailgate provided above, the present application provides a vehicle control method, a control device and a vehicle; through the embodiments of the present application, it is possible to detect the target state of the trunk in the vehicle when opening or closing the tailgate, thereby determining the target height of the vehicle chassis from the ground according to the target state of the trunk, and controlling the vehicle chassis according to the target height, making it easier for users to take and place items, thereby improving the user experience during vehicle use.

[0095] Below is Figure 1 and Figure 4 As an example, the structure of the vehicle tailgate shown in FIG. Figure 5 and Figure 6 The vehicle control method provided in the embodiment of the present application is described in detail.

[0096] Figure 5 It is a flow chart of a vehicle control method provided in an embodiment of the present application.

[0097] For example, Figure 5 The control method 400 shown can be executed by a vehicle having the above-mentioned tailgate structure; or, it can be executed by a body domain controller in a vehicle having the above-mentioned tailgate structure; or, it can be executed by a processor or chip in a body domain controller in a vehicle having the above-mentioned tailgate structure.

[0098] like Figure 5 As shown, the control method 400 includes S410 to S430 , which will be described in detail below.

[0099] S410: If an opening instruction for the lower tailgate of the vehicle is received, a target state of the trunk of the vehicle is detected.

[0100] The tailgate of a vehicle is the door of the trunk of the vehicle. The tailgate of the vehicle includes an upper tailgate and a lower tailgate. The upper tailgate and the lower tailgate are open up and down. Figure 1 The tailgate structure shown is similar to Figure 3 Tailgate structure shown; the trunk target state is used to indicate whether items are present in the trunk.

[0101] For example, the command to open the tailgate of the vehicle may be to touch the opening button of the tailgate, or to send a voice command to control the tailgate through voice control in the vehicle, or to use a remote control key, or to use a mobile phone APP, etc.

[0102] It should be understood that the control instructions for the lower tailgate of the vehicle can be any method in the prior art, and this application does not impose any limitation on this.

[0103] Exemplarily, if an opening command of the lower tailgate of the vehicle is detected, the target state of the vehicle trunk is determined; for example, the target state of the trunk can be detected by installing a radar detection device, a camera, etc. in the trunk.

[0104] S420, determining a target height according to the target state of the trunk; the target height is used to indicate the height between the vehicle chassis and the ground.

[0105] Illustratively, the height between the vehicle chassis and the ground is determined according to the target state of the trunk; the height between the vehicle chassis and the ground determines the height between the trunk and the ground, that is, the lower the height between the vehicle chassis and the ground, the lower the height between the trunk and the ground.

[0106] Example 1: There is no item in the trunk.

[0107] Optionally, determining a target height according to a target state of the trunk includes:

[0108] If the target state of the trunk indicates that there is no object in the trunk, determining the target height to be a first preset height; or

[0109] If the target state of the trunk indicates that no object is present in the trunk, the target height is determined based on the detected volume of the target object carried by the target user.

[0110] Optionally, determining the target height according to the detected volume of the target item carried by the target user includes:

[0111] Determine the target height based on the volume of the target object and the height of the target user.

[0112] Exemplarily, the target height is determined based on the volume of the target item and the height of the target user; when the height of the target user remains unchanged, the larger the volume of the target item, the lower the target height; when the volume of the target item remains unchanged, the higher the height of the target user, the lower the target height, thereby ensuring the convenience of the target user in placing items in the trunk.

[0113] In one example, it is assumed that the first preset height can be any value between 11 cm and 15 cm; when the vehicle detects that there is no item in the trunk, the vehicle can detect whether the target user can be detected within the preset range of the trunk; for example, if the target user is detected within 1.5 meters in the trunk, it means that the target user has a need to close the trunk or place the target item in the trunk. At this time, in order to facilitate the target user to put the target item he carries into the trunk, the height of the vehicle chassis and the ground can be determined to be 14 cm.

[0114] In another example, when the vehicle detects that there are no items in the trunk, it can detect whether the target user can be detected within a preset range of the trunk. For example, if the target user is detected within 1.5 meters of the trunk, it indicates that the target user has a desire to close the trunk or place a target item in the trunk. Because the effort required to place target items of different sizes in the trunk varies, smaller items may be lighter and require less effort to place in the trunk. Therefore, the height of the vehicle chassis above the ground can be further determined based on the size of the target item carried by the target user. The specific implementation method can be referred to the description of the subsequent cases 1 to 4, which will not be repeated here.

[0115] In an embodiment of the present application, when determining the target height of the chassis based on the target items carried by the target user, the height of the target user (i.e., the height of the target user) needs to be considered; since target users of different heights feel comfortable at different target heights when placing items in the trunk; therefore, determining the target height of the chassis based on the volume of the target item and the height of the target user can better meet the needs of target users of different heights, thereby improving the convenience of different target users when placing items in the trunk of the vehicle.

[0116] Exemplarily, determining the target height of the vehicle chassis according to the height of the target user and the volume of the target object can be divided into the following four cases, which are described in detail below.

[0117] Case 1:

[0118] Optionally, determining the target height based on the volume of the target object and the height of the target user includes:

[0119] If the height of the target user is greater than or equal to the preset height threshold, and the volume of the target object is smaller than the preset volume, the target height is determined to be the first target height.

[0120] Exemplarily, the preset height threshold is used to divide the height of the target user; when the height of the target user is greater than the preset height threshold, it indicates that the target user is tall. If the chassis is too low, the target user needs to bend down when placing items in the trunk, which is more laborious, so the chassis height needs to be adjusted; the preset volume is used to divide the volume of the target item; when the volume of the target item is greater than the preset volume, it indicates that the target item is heavy. If the chassis is too high, it will be more laborious to place the target item, so the chassis height needs to be adjusted.

[0121] For example, the preset height threshold is 180cm (centimeter) and the preset volume is 600cm 3 Before the tailgate is opened, the current height of the chassis is 20cm; if the tailgate opening command is received, the target state of the trunk in the vehicle is detected, indicating that there is no object in the trunk, and the target user can be detected within the preset range of the trunk; and the target user is detected to be 190cm tall, which is greater than the preset height threshold, indicating that the target user is tall; the volume of the target object is 300cm 3 If the volume is smaller than the preset volume, it indicates that the target item is small. If the chassis height is too low, the user needs to bend down to place the target item, which affects the user experience. Therefore, the target height is determined to be 30 cm, that is, the chassis of the vehicle is controlled to rise 10 cm to a height of 30 cm from the ground, making it easier for taller users to place smaller items in the trunk.

[0122] It should be noted that the above is an example of the preset height threshold, the preset volume, the first target height and the current height of the chassis, and this application does not impose any limitation on this.

[0123] Case 2:

[0124] Optionally, if the height of the target user is greater than or equal to a preset height threshold, and the volume of the target object is greater than or equal to a preset volume, the target height is determined to be the second target height.

[0125] Among them, the first target height is greater than the second target height; the first target height is greater than the current height, and the current height is used to represent the height between the vehicle chassis and the ground when the start command is detected.

[0126] For example, the preset height threshold is 180cm (centimeter) and the preset volume is 600cm 3 , the current height of the chassis before the tailgate is opened is 20cm; if the tailgate opening command is received, the target state of the trunk in the vehicle is detected to indicate that there is no item in the trunk, and the target user can be detected within the preset range of the trunk; and the target user is detected to be 190cm tall, which is greater than the preset height threshold, indicating that the target user is tall; the volume of the target item is 900cm 3 , which is greater than the preset volume, indicating that the target item is large and not easy to place in the trunk. Placing the target item requires more effort, which affects the target user's experience. Therefore, a target height of 10 cm is determined, that is, the vehicle chassis is controlled to drop 10 cm to a height of 10 cm from the ground, making it easier for taller users to place larger items in the trunk.

[0127] It should be noted that the above is an example of the preset height threshold, the preset volume, the second target height and the current height of the chassis, and this application does not impose any limitation on this.

[0128] For the above situations 1 and 2, since when the height of the target user is greater than or equal to the preset height threshold and the volume of the target item is less than the preset volume, it means that the user with taller height is carrying a target item with smaller volume, and at this time the target height is determined to be the second target height, and the first target height is greater than the current height; when the height of the target user is greater than or equal to the preset height threshold, and the volume of the target item is greater than or equal to the preset volume, it means that the user with taller height is carrying a target object with larger volume, and the target height is determined to be the second target height; through the above scheme, the target height of the vehicle chassis and the ground can be determined according to the height of the target user and the volume of the target item; thereby achieving different chassis heights of the vehicle when a taller user places items of different volumes in the trunk, improving the intelligence level of the vehicle chassis height adjustment, and better meeting the needs of users.

[0129] Case 3:

[0130] Optionally, determining the target height based on the volume of the target object and the height of the target user includes:

[0131] If the height of the target user is less than the preset height threshold and the volume of the target object is less than the preset volume, the target height is determined to be the third target height.

[0132] For example, the preset height threshold is 180cm (centimeter) and the preset volume is 600cm 3 , the current height of the chassis before the tailgate is opened is 20cm; if the tailgate opening command is received, the target state of the trunk in the vehicle is detected to indicate that there is no item in the trunk, and the target user can be detected within the preset range of the trunk; and the target user is detected to be 160cm tall, which is less than the preset height threshold, indicating that the target user is short; the volume of the target item is 300cm 3 , which is smaller than the preset volume, indicates that the target item is small and easy to place in the trunk; if the chassis height is too high or too low, it will affect the target user's experience; therefore, the target height is determined to be 15cm, that is, the chassis of the vehicle is controlled to drop 5cm to a height of 15cm from the ground, making it easier for shorter users to place smaller items in the trunk.

[0133] It should be noted that the above is an example of the preset height threshold, the preset volume, the third target height and the current height of the chassis, and this application does not impose any limitation on this.

[0134] Case 4:

[0135] Optionally, if the height of the target user is less than a preset height threshold and the volume of the target object is greater than or equal to a preset volume, the target height is determined to be a fourth target height.

[0136] The third target height is greater than the fourth target height, and the fourth target height is less than the current height. The current height is used to indicate the height between the vehicle chassis and the ground when the tailgate of the vehicle is not opened.

[0137] For example, the preset height threshold is 180cm (centimeter) and the preset volume is 600cm 3 , the current height of the chassis before the tailgate is opened is 20cm; if the tailgate opening command is received, the target state of the trunk in the vehicle is detected to indicate that there is no item in the trunk, and the target user can be detected within the preset range of the trunk; and the target user is detected to be 160cm tall, which is less than the preset height threshold, indicating that the target user is short; the volume of the target item is 800cm 3, which is greater than the preset volume, indicating that the target item is large and difficult to place in the trunk; if the chassis height is too high, shorter target users will need to expend a certain amount of effort to put the item in the trunk, affecting the target user's experience; therefore, a target height of 5 cm is determined, that is, the vehicle chassis is controlled to drop 15 cm to a height of 5 cm from the ground, making it easier for shorter users to place larger items in the trunk.

[0138] It should be noted that the above is an example of the preset height threshold, the preset volume, the fourth target height and the current height of the chassis, and this application does not impose any limitation on this.

[0139] For the above situations 3 and 4, when the height of the target user is less than the preset height threshold and the volume of the target item is less than the preset volume, it means that the user with shorter height carries a target item with smaller volume; at this time, the target height is determined to be the third target height; when the height of the target user is less than the preset height threshold and the volume of the target item is greater than or equal to the preset volume, it means that the user with shorter height carries a target item with larger volume; at this time, the target height is determined to be the fourth target height; wherein the third target height is greater than the fourth target height; through the above scheme, the target height of the vehicle chassis and the ground can be determined according to the height of the target user and the volume of the target item; and when a user with shorter height places items of different volumes in the trunk, the chassis height of the vehicle is different, thereby improving the intelligence level of the vehicle chassis height adjustment and better meeting the needs of users.

[0140] For example, when determining the target height of the chassis based on the height of the target user and the volume of the target item, the weights of the two factors of the height of the target user and the volume of the target item when determining the target height can be the same or different, and this application does not impose any limitations on this.

[0141] Example 2: There is an item in the trunk.

[0142] Optionally, determining a target height according to a target state of the trunk includes:

[0143] If the target state indicates that there is an item in the trunk, the target height is determined based on the weight of the item;

[0144] The weight of the item is inversely proportional to the target height; the target height is less than the current height, and the current height is used to represent the height between the vehicle chassis and the ground when the tailgate of the vehicle is not opened.

[0145] For example, if there is an item in the trunk, it is determined that the main purpose of opening the tailgate is to take out the stored items from the trunk. Therefore, in order to facilitate the user to take out the items, the target height is determined to be lower than the current height. In addition, the heavier the item, the more difficult it is to take it out. Therefore, the target height is determined to be lower, that is, the weight of the item is inversely proportional to the target height.

[0146] For example, if the weight of the item in the trunk is detected to be 2 kg (kilograms), it indicates that the item is light; therefore, a higher target height (for example, 30 cm) is determined to prevent the target user from bending over to remove the item from the trunk. If the item weighs 10 kg, it indicates that the item is heavy; therefore, a lower target height (for example, 5 cm) is determined to facilitate the user to remove the item from the trunk with less effort.

[0147] It should be noted that the above is an example of the weight of the item and the target height, and this application does not impose any limitation on this.

[0148] In an embodiment of the present application, if it is detected that there are items in the trunk, the target height is determined according to the weight of the items in the trunk. The heavier the items, the lower the target height. Since when there are items in the trunk, it can be determined that the main purpose of the user opening the trunk is to take out the stored items from the trunk. Therefore, the height of the chassis is determined based on the weight of the items. When the weight of the items is greater, the height of the chassis is lower, ensuring that the user can take out the stored items from the trunk more easily.

[0149] Optionally, it also includes:

[0150] If the target status indicates that there is no object in the trunk, the vehicle chassis is controlled to adjust to the current height.

[0151] In an embodiment of the present application, when items in the vehicle trunk are taken out by the user, the vehicle chassis can be controlled to return to the height when the vehicle trunk is not opened; thereby ensuring that when the user takes out items in the trunk and does not need to store items in the trunk, the chassis is controlled to return to the initial height and will not affect the normal driving of the vehicle.

[0152] In a possible implementation, when there is an item in the trunk and the item has a handle, the target height of the vehicle chassis is determined according to the position of the handle of the item in the trunk.

[0153] For example, when there is an item in the trunk of a vehicle and the item has a handle, the user takes out the item by holding the handle when opening the trunk to take out the item; the position of the handle of the item determines the position of the user's hand when taking out the item; therefore, the target height of the chassis from the ground is determined according to the position of the handle of the item; when the position of the handle of the item is higher, the corresponding chassis height is higher; when the position of the handle of the item is lower, the corresponding chassis height is lower; so that when the user takes out the item, the position of the handle of the item is right at the height of the user's hand, thereby ensuring that the user can take out the item with less effort.

[0154] For example, when a user opens the trunk to take out an item, it is detected that the item has a handle, and the handle is at the top of the item, 80 cm above the ground; assuming that the comfortable height for raising the hand when taking the item is 120 cm; in order to ensure that the user can take out the item with less effort, the chassis is determined to rise 40 cm to a position 120 cm above the ground; when it is detected that the handle of the item is in the middle of the item, 60 cm above the ground, in order to ensure that the user can take out the item with less effort, the chassis is determined to rise 60 cm to a position 120 cm above the ground.

[0155] It should be noted that the above are examples of the handle position, target height and comfortable height of the target object, and this application does not impose any limitation on this.

[0156] In one possible implementation, when there is an item in the trunk and the item does not have a handle, the position of the user's hand when taking the item is estimated based on the shape of the item in the trunk of the vehicle, thereby determining the target height of the vehicle chassis.

[0157] For example, when it is detected that there is an item in the trunk and the item has no handle, the position of the target user's hand when taking the item is inferred based on the shape of the item; for example, if the top of the item is smaller and the bottom is larger, the user will most likely take the item out by holding the bottom of the item when taking the item; if the top of the item is larger and the bottom is smaller, the user will most likely take the item out by holding the top of the item when taking the item; if the shape of the top and bottom of the item are roughly the same, the user will hold the middle part of the item when taking the item; therefore, the position of the user's hand when taking out the item is inferred based on the shape of the item, and the height of the vehicle chassis is determined based on the inferred position of the user's hand, ensuring that the user can save effort when taking items of different shapes, thereby improving the user experience.

[0158] For example, if it is detected that there is no handle on an item in the trunk, and the item is smaller at the top and larger at the bottom, it is inferred that the user will grab the item by the bottom when taking it out, that is, the user's hand is estimated to be 40cm above the ground when taking the item. Assuming that the comfortable hand height when taking the item is 120cm, therefore, to ensure that the user can easily take the item out, the chassis is determined to be raised 80cm to a position 120cm above the ground. If it is detected that the item is larger at the top and smaller at the bottom, it is inferred that the user will grab the item by the top when taking it out, that is, the user's hand is estimated to be 80cm above the ground when taking the item. Therefore, to ensure that the user can easily take the item out, the chassis is determined to be raised 40cm to a position 120cm above the ground.

[0159] It should be noted that the above are examples of the shape of the target object, the comfortable height and the target height, and this application does not impose any limitation on this.

[0160] In one possible implementation, if it is detected that the target user has turned on the camping mode, or it is detected that the target user has a need to rest, when controlling the opening of the upper and lower tailgates of the vehicle, the height of the vehicle chassis is controlled according to the height of the target user; the higher the height of the target user, the higher the chassis height, and the shorter the height of the target user, the lower the chassis height, that is, the height of the target user is proportional to the chassis height.

[0161] For example, the correspondence between the target user's height and chassis height may be a functional relationship or a graphical relationship; each height value may correspond to a chassis height.

[0162] It should be understood that the above functional relationship and graphical relationship are examples of the corresponding relationship, and this application does not impose any limitation on this.

[0163] For example, when it is detected that the target user has turned on the camping mode or has the need to sit on the lower tailgate of the vehicle to rest, the target user's height information is collected according to the camera, and the lifting height of the chassis is adjusted according to the target user's height information, thereby ensuring that target users of different heights can sit on the lower tailgate of the vehicle more comfortably, thereby improving the user experience.

[0164] For example, when the user turns on the camping mode, or when it is detected that the target user needs to sit on the lower tailgate to rest, if the target user is detected to be 180 cm tall, the chassis is controlled to rise to a position 60 cm from the ground so that the taller target user can sit more comfortably on the lower tailgate of the vehicle; when the target user is detected to be 160 cm tall, the chassis is controlled to rise to a position 50 cm from the ground so that the shorter target user can sit more comfortably on the lower tailgate of the vehicle.

[0165] It should be noted that the above is an example of the height and chassis height of the target user, and this application does not impose any limitation on this.

[0166] S430: Control the vehicle chassis according to the target height.

[0167] Illustratively, the vehicle controls the chassis of the vehicle to rise or fall to the target height based on the determined target height between the chassis and the ground.

[0168] Optionally, during the process of controlling the chassis to rise and fall, the vehicle uses ultrasonic radar or camera to detect whether there are obstacles around the chassis (such as stones, steps, etc.). If there are obstacles near or below the vehicle chassis, in order to avoid collision, the vehicle chassis stops descending and sends a prompt message to remind the user that the current chassis cannot rise or descend normally.

[0169] For example, if the current height of the vehicle chassis is 13 cm before the tailgate is opened, and the target height is determined to be 5 cm, the chassis is controlled to drop 8 cm to reach the target height; if the target height is determined to be 17 cm, the chassis is controlled to rise 4 cm to reach the target height.

[0170] It should be noted that the above is an example of the current altitude and the target altitude, and this application does not impose any limitation on this.

[0171] Optionally, it also includes:

[0172] If an opening command for the vehicle's upper tailgate is detected, determining whether a user is detected within a preset range;

[0173] If a user is detected within the preset range, the user's height is identified;

[0174] Determine the opening degree of the tailgate according to the height of the target user.

[0175] For example, when the vehicle detects an instruction to open the tailgate, it detects the user and identifies the user's height through a camera installed at the rear of the vehicle, determines the opening degree of the tailgate based on the identified user's height, and controls the tailgate to open to an appropriate height based on the determined opening degree; the higher the height of the target user, the greater the opening degree of the tailgate.

[0176] Exemplarily, the opening degree of the upper tailgate is determined according to a mapping relationship between the target user height and the opening degree of the upper tailgate.

[0177] Exemplarily, the mapping relationship may refer to a functional relationship; for example, a direct proportional function; for example, the taller the target user is, the greater the degree of opening of the upper tailgate is; the shorter the target user is, the smaller the degree of opening of the upper tailgate is.

[0178] Exemplarily, the mapping relationship may also be a graph relationship; the height of each target user may correspond to an upper tailgate opening degree.

[0179] It should be understood that the above-mentioned mapping relationship is illustrated by using functional relationship and graphical relationship, and this application does not impose any limitation on this.

[0180] In an embodiment of the present application, if an opening command for the upper tailgate in a vehicle is detected, it is determined whether a target user is detected within a preset range at the rear of the vehicle; if a target user is detected, the height of the target user is identified, and the opening degree of the upper tailgate is determined based on the height of the target user; the opening height of the upper tailgate is intelligently set to a suitable height of the target user to prevent a collision with the target user due to the upper tailgate opening height being too low; or the upper tailgate opening height being too high to make it inconvenient for the target user to touch the tailgate.

[0181] Figure 6 It is a flow chart of another vehicle control method provided in an embodiment of the present application.

[0182] For example, Figure 6 The control method 500 shown can be executed by a vehicle having the above-mentioned tailgate structure; or, can be executed by a body domain controller in a vehicle having the above-mentioned tailgate structure; or, can be executed by a processor or chip in a body domain controller in a vehicle having the above-mentioned tailgate structure.

[0183] like Figure 6 As shown, the control method 500 includes S510 to S540 , which will be described in detail below.

[0184] S510: Receive an opening instruction for the lower tailgate of the vehicle.

[0185] For example, the vehicle body domain controller receives an opening instruction for the lower tailgate, which may be by touching an opening button of the lower tailgate, sending a voice command, or using a remote control key.

[0186] It should be understood that the control instructions for the lower tailgate of the vehicle can be any method in the prior art, and this application does not impose any limitation on this.

[0187] S520, detecting a target state of a trunk in the vehicle.

[0188] Optionally, the implementation of S520 can refer to Figure 3 The relevant description of S410 is omitted here.

[0189] S531: If the target state indicates that there is no object in the trunk, determine the target height to be a first preset height.

[0190] Optionally, the implementation of S531 can refer to Figure 5 The relevant description of S420 is not repeated here.

[0191] S532: If the target status indicates that there is no object in the trunk, determine a target height based on the detected target object carried by the target user.

[0192] For example, if the target state indicates that there is no item in the trunk, it can be determined that the vehicle opens the tailgate mainly for the purpose of storing items in the trunk; therefore, the target height is determined according to the target item carried by the user.

[0193] In one case, the target height of the chassis from the ground is related to the height of the target user; that is, the target height is determined based on the height of the target user and the target object.

[0194] Optionally, the implementation of S532 can refer to Figure 5 The relevant description of S420 is not repeated here.

[0195] S533: If the target state indicates that there is an item in the trunk, determine the target height based on the weight of the item.

[0196] For example, if the target state indicates that there is an item in the trunk, it can be determined that the user's purpose of opening the tailgate is most likely to take the item from the trunk; therefore, the target height of the chassis from the ground is determined according to the weight of the item; if the weight of the item is greater, it is more difficult to take the item out of the trunk; therefore, the target height of the chassis is controlled to be lower, so that the target user can take the item from the trunk with less effort.

[0197] Optionally, the implementation of S333 can refer to Figure 5 The relevant description of S420 is not repeated here.

[0198] S540: If the target height is greater than the current height, the vehicle chassis is controlled to rise; if the target height is less than the current height, the vehicle chassis is controlled to fall.

[0199] The current height is the height between the vehicle chassis and the ground when the tailgate is not opened.

[0200] Exemplarily, the vehicle controls the raising and lowering of the chassis according to the determined target height of the tailgate from the ground; that is, when the target height is higher than the current height, the chassis is controlled to be raised; when the target height is lower than the current height, the chassis of the vehicle is controlled to be lowered.

[0201] In an embodiment of the present application, after receiving the opening command of the lower tailgate, the vehicle detects the target state of the trunk, determines the target height of the chassis based on the judgment result of whether there are items in the trunk and other influencing factors (such as the height of the target user and the weight of the items in the trunk), and controls the raising and lowering of the chassis based on the determined target height; this facilitates users to take and place items, and improves the user experience during vehicle use.

[0202] Figure 7 It is a schematic diagram of a process of lifting a vehicle chassis provided in an embodiment of the present application.

[0203] In one case, the process of controlling the chassis to rise or fall is as follows Figure 7 As shown in (a) in .

[0204] S601: The body domain controller receives a lower tailgate open / close instruction.

[0205] S602: The lower tailgate controller receives a lower tailgate opening / closing instruction.

[0206] S603 controls the opening or closing of the tailgate.

[0207] S604: The suspension controller receives a lower tailgate opening / closing instruction.

[0208] S605, controls chassis lowering / raising.

[0209] For example, when the body domain controller receives a lower tailgate opening or closing instruction, the body domain controller simultaneously sends a lower tailgate opening or closing instruction to the suspension controller, so that the vehicle can control the lifting and lowering of the vehicle chassis while controlling the opening and closing of the lower tailgate.

[0210] In one case, the process of controlling the chassis to rise or fall is as follows Figure 7 As shown in (b) in .

[0211] S606: The body domain controller detects that the lower tailgate is in the open state.

[0212] S607: The gravity sensing module detects gravity.

[0213] S608, controls chassis lowering / raising.

[0214] For example, when the vehicle detects that the lower tailgate is in an open state, it obtains data detected by the gravity sensing module; wherein, the gravity sensing module is installed on the inner side of the lower tailgate of the vehicle. When the gravity sensing module detects gravity, the chassis is controlled to be lowered; when the gravity sensing module does not detect gravity, the chassis is controlled to be raised.

[0215] In an embodiment of the present application, the corresponding lowering or raising of the vehicle chassis is controlled by detecting the opening or closing command of the lower tailgate, or when the lower tailgate of the vehicle is in the open state, the lowering or raising of the vehicle chassis is determined by detecting the gravity data on the inner side of the lower tailgate; this is convenient for users to take and put items in the trunk after opening the tailgate.

[0216] Figure 8 This is another flow chart of opening the tailgate provided in an embodiment of the present application.

[0217] S701, the rear camera collects height information.

[0218] Exemplarily, the rear camera is installed at the rear of the vehicle to ensure that the camera can collect the user's height information.

[0219] S702: The calculation unit calculates the target height according to the height information.

[0220] Exemplarily, the opening degree of the upper tailgate is determined according to a mapping relationship between the target user height and the opening degree of the upper tailgate.

[0221] Exemplarily, the mapping relationship may refer to a functional relationship; for example, a direct proportional function; for example, the taller the target user is, the greater the degree of opening of the upper tailgate is; the shorter the target user is, the smaller the degree of opening of the upper tailgate is.

[0222] Exemplarily, the mapping relationship may also be a graph relationship; the height of each target user may correspond to an upper tailgate opening degree.

[0223] It should be understood that the above-mentioned mapping relationship is illustrated by using functional relationship and graphical relationship, and this application does not impose any limitation on this.

[0224] S703: The body domain controller detects the tailgate opening instruction.

[0225] S704: The upper tailgate controller receives an upper tailgate opening instruction and a target height.

[0226] S705, controlling the tailgate to open to a target height.

[0227] Optionally, the implementation of S701 to S705 can refer to Figure 5 The relevant description of S430 is not repeated here.

[0228] In an embodiment of the present application, if an opening command of an upper tailgate in a vehicle tailgate is detected, it is determined whether a target user is detected within a preset range at the rear of the vehicle; if a target user is detected, the height of the target user is identified, and the opening degree of the upper tailgate is determined based on the height of the target user; the opening height of the upper tailgate is intelligently set to a suitable height of the target user to prevent a collision with the target user due to the upper tailgate opening height being too low; or the upper tailgate opening height being too high to make it inconvenient for the target user to touch the tailgate.

[0229] Figure 9 This is a schematic flow chart of vehicle locking provided in an embodiment of the present application.

[0230] In one case, the process of controlling the vehicle locking is as follows Figure 9 As shown in (a) in .

[0231] S801: The body domain controller receives a tailgate locking instruction.

[0232] S802: If the vehicle meets a first preset condition, the body domain controller sends a command to the tailgate controller.

[0233] Exemplarily, the first preset condition includes detecting that the vehicle is turned off, the vehicle door locks are in the closed state, and the vehicle remote control key is not in the cab; when the vehicle simultaneously meets all the conditions in the first preset condition, it is detected that the switch of the vehicle tailgate is touched, and the body domain controller sends a control instruction to the tailgate controller.

[0234] S803: The tailgate controller receives a control instruction.

[0235] S804, controls the locking of the four doors and the upper and lower tailgates, and controls the closing of the windows / headlights / sunroof.

[0236] For example, the vehicle sends a control instruction to the tailgate controller to control the upper tailgate and the lower tailgate in the tailgate to be in a closed state; the body domain controller controls the vehicle's door locking and controls the closing of windows, lights and sunroof.

[0237] In one case, the process of controlling the vehicle locking is as follows Figure 9 As shown in (b) in .

[0238] S805: The vehicle body domain controller receives a tailgate locking instruction.

[0239] S806: After detecting that the vehicle meets a second preset condition, the body domain controller sends a command to the tailgate controller.

[0240] Exemplarily, the second preset condition includes detecting that the vehicle is turned off, the vehicle's door locks are in a closed state, the vehicle's remote control key is not in the cab, and the lower tailgate of the vehicle is in a closed state; when the vehicle simultaneously meets all the conditions in the second preset condition, it is detected that the switch of the vehicle's upper tailgate is touched, and the body domain controller sends a control instruction to the upper tailgate controller.

[0241] S807: The upper tailgate controller receives the control instruction.

[0242] S808 controls the locking of the four doors and the upper tailgate, and the closing of the windows, lights, and sunroof.

[0243] For example, the vehicle sends a control instruction to the upper tailgate controller to control the upper tailgate to be in a closed state; the body domain controller controls the vehicle's door locking, and controls the closing of windows, lights and sunroof.

[0244] In an embodiment of the present application, by detecting whether the vehicle meets the preset conditions, when the preset conditions are met and it is detected that the vehicle has touched the tailgate lock switch, the vehicle's tailgate is controlled to be locked while the vehicle's doors, sunroof, windows and lights are controlled to be closed. This saves the time required to close the entire vehicle through the remote control key after touching the tailgate switch to close the tailgate. At the same time, it also prevents the risk of the user forgetting to lock the vehicle after closing the tailgate, thereby improving the intelligence of human-vehicle interaction.

[0245] It should be understood that the above examples are intended to help those skilled in the art understand the embodiments of the present application, and are not intended to limit the embodiments of the present application to the specific numerical values or specific scenarios illustrated.

[0247] Figure 10 It is a structural schematic diagram of a vehicle control device provided in an embodiment of the present application.

[0248] For example, Figure 10 As shown, the control device 400 includes:

[0249] A detection module 910 is configured to detect a target state of a trunk in the vehicle upon receiving an opening command for a lower tailgate in the vehicle; wherein the target state of the trunk indicates whether there is an item in the trunk;

[0250] A determination module 920 is configured to determine a target height according to a target state of the trunk, where the target height indicates the height between the vehicle chassis and the ground;

[0251] The control module 930 is used to control the vehicle chassis according to the target height.

[0252] Optionally, as an embodiment, the determining module 920 is specifically configured to:

[0253] If there is no object in the trunk, the target height is determined to be a first preset height; or,

[0254] If there is no object in the trunk, the target height is determined based on the volume of the target object carried by the detected target user.

[0255] Optionally, as an embodiment, the determining module 920 is specifically configured to:

[0256] Determine the target height based on the volume of the target object and the height of the target user.

[0257] Optionally, as an embodiment, the determining module 920 is specifically configured to:

[0258] If the height of the target user is greater than or equal to the first preset height threshold, and the volume of the target object is less than the preset volume, the target height is determined to be the first target height;

[0259] If the height of the target user is greater than or equal to the first preset height threshold, and the volume of the target object is greater than or equal to the preset volume, determining the target height to be the second target height;

[0260] Among them, the first target height is greater than the second target height; the first target height is greater than the current height, and the current height is used to represent the height between the vehicle chassis and the ground when the vehicle tailgate is not opened.

[0263] If the height of the target user is less than the first preset height threshold, and the volume of the target object is greater than or equal to the preset volume, determining the target height to be a fourth target height;

[0264] The third target height is greater than the fourth target height, and the fourth target height is less than the current height. The current height is used to indicate the height between the vehicle chassis and the ground when the tailgate of the vehicle is not opened.

[0265] Optionally, as an embodiment, the determining module 920 is specifically configured to:

[0266] If there are items in the trunk, determine the target height based on the weight of the items;

[0267] The weight is inversely proportional to the target height; the target height is less than the current height, and the current height is used to represent the height between the vehicle chassis and the ground when the tailgate of the vehicle is not opened.
