[0030] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0031] The following describes the adaptive adjustment method, device, vehicle and program product of the automobile tailgate of the embodiment of the present application with reference to the accompanying drawings. In view of the problem mentioned in the above background technology that in the existing automobile design, the tailgate of many vehicles causes difficulty in use for passengers with shorter stature when in use, the present application provides an adaptive adjustment method for the rear tailgate of an automobile, in which a tailgate opening instruction is received, and the instruction type of the tailgate opening instruction is determined. If the instruction type is a remote control instruction or an in-vehicle control instruction, the surrounding environment data of the vehicle tailgate is obtained, and based on the surrounding environment data of the vehicle tailgate, it is determined whether the vehicle tailgate meets the opening condition. If the vehicle tailgate meets the opening condition, the vehicle tailgate is controlled to open to the maximum height, and the passenger's body height is obtained, and the height of the vehicle tailgate is adjusted to the target opening height according to the passenger's body height. Thus, the problem that the rear tailgate of many vehicles in the existing automobile design causes difficulty in use for passengers with shorter stature when in use is solved, and the needs of passengers of different heights are met in an intelligent way, thereby improving the human-computer interaction experience and overall safety of the automobile.

[0032] The embodiment of the present application includes the following main components:

[0033] 1) Sensor system: Uses multiple sensors such as cameras, infrared sensors, ultrasonic sensors, etc. installed in the vehicle to obtain passenger height data and environmental data in real time.

[0034] 2) Data fusion unit: Integrate and fuse the data obtained from different sensors to obtain more accurate human height information.

[0035] 3) Processing unit: Analyzes sensor data in real time to dynamically adjust the optimal tailgate opening height.

[0036] 4) Execution system: The execution system integrated into the car is responsible for actually controlling the opening height of the car's tailgate, which involves an electric motor or hydraulic system.

[0037] 5) User interface: Provides a display screen to show the currently measured height of the person and adjust the opening height of the tailgate.

[0038] Specifically, Figure 1 A schematic flow chart of a method for adaptively adjusting a rear tailgate of a vehicle provided in an embodiment of the present application.

[0039] It should be noted that the schematic diagram of the sensor installation for collecting human height data is as follows: Figure 2 As shown in the figure, the camera is arranged inside the vehicle and integrated into the rear high-mounted brake light position. When the door is fully opened, the camera's field of view can cover the environment around the rear tailgate. When the door is closed, the camera is facing downward, and the camera's field of view can only cover the environment inside the trunk. When the user needs to open the rear tailgate, he only needs to confirm the relevant privacy regulations for the first time. At the same time, when the rear tailgate is opened, the camera starts to detect the passenger's body height data, without the need for real-time judgment, saving energy consumption and improving system stability.

[0040] like Figure 1 As shown, the self-adaptive adjustment method of the rear tailgate of the automobile comprises the following steps:

[0041] In step S101 , a tailgate opening instruction is received, and the instruction type of the tailgate opening instruction is determined.

[0042] Among them, the command types of tailgate opening commands include remote control commands, in-vehicle control commands and tailgate manual control commands. Among them, remote control commands include vehicle key control commands and mobile phone app control commands; in-vehicle control commands include voice control commands, vehicle central control screen control commands, and in-vehicle physical switch button control commands; tailgate manual control commands include tailgate switch button control commands and foot dynamic sensing control commands.

[0043] Specifically, when the vehicle controller receives a tailgate opening command, the tailgate is unlocked, and then the command type of the tailgate opening command is determined. For example, the user can remotely issue a tailgate opening command through a mobile phone APP, or issue the tailgate opening command inside the vehicle, or press the tailgate opening switch at the rear tailgate of the vehicle to issue the tailgate opening command.

[0044] In step S102, if the command type is a remote control command or an in-vehicle control command, the surrounding environment data of the vehicle's tailgate is acquired.

[0045] It should be understood that if the command type is a remote control command or an in-vehicle control command, multiple sensors collect the surrounding environment data of the vehicle's tailgate, including an ultrasonic sensor that obtains obstacle data at the vehicle's tailgate and an infrared sensor that senses the temperature data of objects in the vehicle's rear environment in real time, and transmits the data to the controller. The controller analyzes the surrounding environment data to determine whether the vehicle's tailgate meets the opening conditions, thereby avoiding the vehicle's tailgate colliding with other objects or passers-by when opening, thereby causing damage to the tailgate or personal injury.

[0046] In step S103, it is determined whether the vehicle tailgate meets the opening conditions based on the surrounding environment data of the vehicle tailgate. If the vehicle tailgate meets the opening conditions, the vehicle tailgate is controlled to open to the maximum height, and the passenger's body height is obtained, and the height of the vehicle tailgate is adjusted to the target opening height according to the passenger's body height.

[0047] Among them, the opening condition can be understood as there is a passenger standing facing the tailgate within 10cm-30cm (the specific range can be set by relevant personnel in this field) for more than a certain period of time, and there are no other obstacles within 10cm-30cm of the tailgate that prevent the tailgate from opening. At this time, the tailgate meets the opening condition.

[0048] Specifically, the controller analyzes the obstacle data at the rear tailgate of the vehicle acquired by the ultrasonic sensor and the temperature data of objects in the rear environment of the vehicle sensed in real time by the infrared sensor to determine whether the tailgate meets the opening conditions.

[0049] For example, when a passenger stands facing the tailgate within 10cm-30cm of the tailgate for more than a certain period of time and there are no other obstacles, the tailgate automatically opens to the maximum height. Multiple sensors collect the passenger's body height at the tailgate and transmit it to the controller. The controller determines the target opening height of the tailgate based on the passenger's body height.

[0050] As a result, the system can meet the user's needs for opening the tailgate in different scenarios and be more intelligent, thereby improving the user experience of the vehicle.

[0051] Optionally, in some embodiments, the height of the vehicle's tailgate is adjusted to a target opening height based on the passenger's body height, including: determining whether the passenger's body height is in a preset height range; if the passenger's body height is in the preset height range, determining the current height range of the body height based on the passenger's body height; and obtaining the target opening height corresponding to the body height based on a mapping relationship between the current height range and the optimal door opening height.

[0052] Specifically, the controller analyzes the height of the passenger at the rear tailgate of the vehicle to determine whether the current opening height of the tailgate of the vehicle meets the height of the person. Since the heights of different people vary greatly, and people are constantly moving, they may bend over, tiptoe, raise their heads, lower their heads, and multiple people may affect the height judgment. The specific solution of the embodiment of the present application is:

[0053] like Figure 3As shown, the user's height is divided into regional ranges. First, the conventional height range is measured in advance, and the range is evenly divided. Then, the suitable door opening height values ​​for each range are calculated, and then the suitable door opening height values ​​for each area are bound to the regional space database. The controller only needs to match the height information transmitted by the camera with the pre-divided eye area range, without the need to calculate the tailgate opening height in real time, and avoid frequent adjustments to the tailgate height.

[0054] For example, if the passenger's height is 163 cm, it is determined that the passenger's height is in the preset height range. At this time, the current height range of the passenger's height is determined based on the passenger's height. Figure 3 The middle is area 3, so that the target opening height corresponding to the body height is obtained according to the mapping relationship between the current height range and the optimal door opening height, and the height of the vehicle's tailgate is adjusted to the target opening height.

[0055] It should be noted that when there are multiple people, the body height of the person closest to the tailgate will be used as the basis for judgment.

[0056] This solves the problem of the character's height constantly changing due to movements, and at the same time adjusts the height for subsequent calculations, greatly reducing the amount of calculation required by the controller.

[0057] Optionally, in some embodiments, after determining whether the passenger's body height is within a preset height range, the method includes: determining whether the passenger's body height is within a first height range; if the passenger's body height is within the first height range, adjusting the height of the vehicle's tailgate to a first preset height based on the passenger's body height; if the passenger's body height is within a second height range, adjusting the height of the vehicle's tailgate to a second preset height based on the passenger's body height.

[0058] Among them, the first height range is 0cm-140cm, and the second height range is greater than 200cm.

[0059] Among them, the first preset height can be a threshold value set in advance by the user, a threshold value obtained through a limited number of experiments, or a threshold value obtained through a limited number of computer simulations, and no specific limitation is made here. The second preset height is the maximum opening height of the tailgate.

[0060] For example, if the passenger's body height captured by the camera is lower than 140cm, the height of the vehicle's tailgate will be lowered to the first preset height. When the passenger's height captured by the camera is higher than 200cm, the vehicle's tailgate will be controlled to open to the maximum opening height, and the system will continue to verify whether the passenger's body height is within the preset height range.

[0061] Optionally, in some embodiments, after adjusting the height of the vehicle's tailgate to a target opening height according to the passenger's body height, the process includes: determining whether a door closing command is received; and if a door closing command is received, controlling the vehicle's tailgate to close.

[0062] It can be understood that when the controller determines that the passenger's body height is within the preset height range, it determines whether a door closing command is received. When no door closing command is received, a loop is performed to collect the passenger's body height at the rear tailgate of the vehicle until the controller analyzes the image, thereby adjusting the height of the rear tailgate of the vehicle. When a door closing command is received, the tailgate of the vehicle executes the closing action.

[0063] Optionally, in some embodiments, whether the vehicle's tailgate meets the opening conditions is determined based on the surrounding environment data of the vehicle's tailgate, including: if the vehicle's tailgate does not meet the opening conditions, then when the command type of the tailgate opening command is a remote control command, the remote terminal is controlled to perform an acoustic alarm, and a tailgate opening failure reminder is sent to the remote terminal's display screen for display; or, when the command type of the tailgate opening command is an in-vehicle control command, the vehicle is controlled to perform an acoustic alarm and / or an optical alarm, and a tailgate opening failure reminder is sent to the vehicle's central control screen for display.

[0064] It should be understood that when the controller determines that the vehicle's tailgate does not meet the conditions for opening, if the command type of the tailgate opening command is a remote control command, the remote terminal is controlled to give an acoustic alarm and at the same time send a tailgate opening failure reminder to the remote terminal for display.

[0065] If the command type of the tailgate opening command is an in-vehicle control command, the vehicle is controlled to give an acoustic alarm and / or a visual alarm, such as controlling a speaker to give an alarm, or flashing a warning light, and at the same time, a tailgate opening failure reminder is sent to the vehicle's central control screen for display, such as Figure 4 As shown, the sensors and cameras on the vehicle collect data about the vehicle's surrounding environment and temperature data of objects in the vehicle's rear environment at the same time, and the controller cyclically determines whether the vehicle's rear tailgate meets the conditions for opening the door.

[0066] Optionally, in some embodiments, the above-mentioned adaptive adjustment method of the automobile tailgate includes: if the instruction type is a manual tailgate control instruction, controlling the vehicle's tailgate to open to a maximum height, and obtaining the passenger's body height, determining the target opening height of the vehicle's tailgate according to the passenger's body height, and controlling the vehicle's tailgate based on the target opening height.

[0067] It should be understood that if the command type is a manual tailgate control command, the controller skips determining whether the vehicle's tailgate meets the opening conditions, controls the vehicle's tailgate to open to the maximum height, then obtains the passenger's body height, determines the target opening height of the vehicle's tailgate based on the passenger's body height, and controls the vehicle's tailgate based on the target opening height.

[0068] In order to ensure the safety of the vehicle's tailgate during the adjustment process, the system integrates safety sensors to avoid collisions or other unexpected situations during the adjustment process.

[0069] In an embodiment of the present application, when the controller determines that the vehicle's tailgate does not perform an opening action, the vehicle's tailgate is in a waiting state, while cyclically collecting surrounding environment data and ambient temperature data, and the driver can also choose to manually adjust the height of the tailgate to meet specific needs.

[0070] In order to enable those skilled in the art to further understand the adaptive adjustment method of the automobile tailgate of the embodiment of the present application, the following is a detailed description in conjunction with a specific embodiment. Figure 5 shown.

[0071] Step 1: The tailgate is unlocked after receiving the tailgate opening command;

[0072] Step 2: Determine the command type of the tailgate opening command. If the command type of the tailgate opening command is a remote control command or an in-vehicle control command, execute step 3. If the command type of the tailgate opening command is a tailgate manual opening and closing command, execute step 8.

[0073] Step 3: The ultrasonic sensor obtains environmental data at the rear tailgate;

[0074] Step 4: The controller determines whether the tailgate can be opened according to the environmental data. If yes, it goes to step 5; otherwise, it goes to step 6.

[0075] Step 5: The infrared sensor senses the ambient temperature data at the tailgate;

[0076] Step 6: The vehicle alarm reminds, or the vehicle's HMI displays a reminder;

[0077] Step 7: The controller determines whether the tailgate can be opened based on the ambient temperature data. If so, it determines that the tailgate meets the opening conditions and executes step 8;

[0078] Step 8: Open the tailgate to the maximum height;

[0079] Step 9: The camera collects a real-time image of the person at the tailgate of the vehicle to obtain the person's height;

[0080] Step 10: The controller analyzes the image to determine whether the opening height of the vehicle tailgate meets the height range of the person. If yes, step 11 is executed; otherwise, step 12 is executed.

[0081] Step 11: Determine whether the tailgate closing signal is received, if received, the tailgate is closed, if not received, repeat step 9;

[0082] Step 12: Adjust the tailgate opening height.

[0083] According to the adaptive adjustment method of the rear tailgate of a car proposed in the embodiment of the present application, a tailgate opening command is received, and the command type of the tailgate opening command is determined. If the command type is a remote control command or an in-car control command, the surrounding environment data of the rear tailgate of the vehicle is obtained, and based on the surrounding environment data of the rear tailgate of the vehicle, it is determined whether the rear tailgate of the vehicle meets the opening conditions. If the rear tailgate of the vehicle meets the opening conditions, the rear tailgate of the vehicle is controlled to open to the maximum height, and the body height of the passenger is obtained, and the height of the rear tailgate of the vehicle is adjusted to the target opening height according to the body height of the passenger. In this way, the problem that the rear tailgate of many vehicles in the existing car design causes difficulty in use for passengers with shorter stature when in use is solved, and it can adapt to passengers of different statures and improve the convenience and comfort of car use. In addition, the system design takes into account safety and real-time performance to ensure reliable operation in various traffic scenarios.

[0084] Next, the adaptive adjustment device for the rear tailgate of a vehicle proposed in accordance with an embodiment of the present application will be described with reference to the accompanying drawings.

[0085] Figure 6 It is a block diagram of an adaptive adjustment device for a rear tailgate of a vehicle according to an embodiment of the present application.

[0086] like Figure 6 As shown, the self-adaptive adjustment device 10 for the rear tailgate of a vehicle includes: a judgment module 100 , an acquisition module 200 and a first control module 300 .

[0087] Among them, the judgment module 100 is used to receive the tailgate opening instruction and determine the instruction type of the tailgate opening instruction; the acquisition module 200 is used to obtain the surrounding environment data of the vehicle's tailgate if the instruction type is a remote control instruction or an in-vehicle control instruction; the first control module 300 is used to determine whether the vehicle's tailgate meets the opening conditions based on the surrounding environment data of the vehicle's tailgate. If the vehicle's tailgate meets the opening conditions, the vehicle's tailgate is controlled to open to the maximum height, and the passenger's body height is obtained, and the height of the vehicle's tailgate is adjusted to the target opening height according to the passenger's body height.

[0088] Optionally, in some embodiments, the above-mentioned adaptive adjustment device 10 for the rear tailgate of the automobile further includes: a second control module, which is used to control the vehicle's rear tailgate to open to the maximum height if the instruction type is a manual tailgate control instruction, and obtain the passenger's body height, and adjust the height of the vehicle's rear tailgate to the target opening height according to the passenger's body height.

[0089] Optionally, in some embodiments, the first control module 300 is further used to: determine whether the passenger's body height is in a preset height range; if the passenger's body height is in the preset height range, determine the current height range of the body height based on the passenger's body height; and obtain the target opening height corresponding to the body height according to the mapping relationship between the current height range and the optimal door opening height.

[0090] Optionally, in some embodiments, after determining whether the passenger's body height is within a preset height range, the first control module 300 is further used to: determine whether the passenger's body height is within a first height range; if the passenger's body height is within the first height range, adjust the height of the vehicle's tailgate to a first preset height based on the passenger's body height; if the passenger's body height is within a second height range, adjust the height of the vehicle's tailgate to a second preset height based on the passenger's body height.

[0091] Optionally, in some embodiments, after determining whether the vehicle tailgate meets the opening conditions based on the surrounding environment data of the vehicle tailgate, the first control module 300 is also used to: if the vehicle tailgate does not meet the opening conditions, then when the command type of the tailgate opening command is a remote control command, control the remote terminal to perform an acoustic alarm, and at the same time send a tailgate opening failure reminder to the remote terminal display screen for display; or, when the command type of the tailgate opening command is an in-vehicle control command, control the vehicle to perform an acoustic alarm and / or an optical alarm, and at the same time send a tailgate opening failure reminder to the vehicle's central control screen for display.

[0092] Optionally, after determining the target opening height of the tailgate according to the passenger's body height, the first control module 300 is further used to: determine whether a door closing command is received; if a door closing command is received, control the vehicle tailgate to close.

[0093] It should be noted that the above explanation of the embodiment of the method for adaptively adjusting the rear tailgate of a car is also applicable to the adaptive adjustment device for the rear tailgate of a car in this embodiment, and will not be repeated here.

[0094] According to the adaptive adjustment device of the rear tailgate of the automobile proposed in the embodiment of the present application, a tailgate opening instruction is received, and the instruction type of the tailgate opening instruction is determined. If the instruction type is a remote control instruction or an in-car control instruction, the surrounding environment data of the vehicle's rear tailgate is obtained, and whether the vehicle's rear tailgate meets the opening conditions is determined based on the surrounding environment data of the vehicle's rear tailgate. If the vehicle's rear tailgate meets the opening conditions, the vehicle's rear tailgate is controlled to open to the maximum height, and the passenger's body height is obtained, and the height of the vehicle's rear tailgate is adjusted to the target opening height according to the passenger's body height. In this way, the problem that the rear tailgate of many vehicles in the existing automobile design causes difficulty in use for passengers with shorter stature when in use is solved, and the needs of passengers of different heights are met in an intelligent way, thereby improving the human-computer interaction experience and overall safety of the automobile.
