Description

Technical Field

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

[0002] More and more car models are equipped with electric tailgate systems, which can automatically open and close the tailgate through corresponding switches or remote control devices, improving the convenience of using the tailgate.

[0003] However, in different vehicle application scenarios, users have different requirements for the time it takes to open or close the door. Existing electric tailgate systems all open and close with a fixed duration, which cannot meet the needs of users in different scenarios.

[0004] Therefore, how to flexibly control the opening and closing time of the vehicle's tailgate is an urgent problem to be solved in order to improve the user's car experience. Summary of the Invention

[0005] The present application provides a vehicle tailgate control method, device and vehicle, which can dynamically adjust the opening or closing time of the vehicle tailgate according to the usage scenario to meet the user's vehicle usage needs in different scenarios.

[0006] In a first aspect, a vehicle tailgate control method is provided, the method comprising: identifying a current target usage scenario of the vehicle; determining a target control duration of the vehicle tailgate based on the target usage scenario, the target control duration comprising at least one of a tailgate opening duration and a tailgate closing duration, the tailgate opening duration indicating the time required to control the vehicle tailgate from a closed state to an open state, and the tailgate closing duration indicating the time required to control the vehicle tailgate from an open state to a closed state; and upon receiving a target control instruction for the vehicle tailgate, controlling the vehicle tailgate based on the target control duration, the target control instruction being used to change a tailgate state of the vehicle tailgate, the tailgate state comprising an open state or a closed state.

[0007] In the above technical solution, this embodiment provides a vehicle tailgate control method: by identifying the vehicle's current target usage scenario, a target tailgate control duration corresponding to the target usage scenario is determined. When a target control instruction for the vehicle tailgate is received, the vehicle tailgate is controlled based on the determined target control duration, changing the tailgate state of the vehicle tailgate. This method dynamically adjusts the vehicle tailgate control duration according to the vehicle's target usage scenario, ensuring that the target tailgate control duration meets the needs of different usage scenarios and improving the flexibility of controlling the tailgate opening and closing duration. In addition, the target control duration includes at least one of the tailgate opening duration and the tailgate closing duration. Different tailgate opening durations, different tailgate closing durations, or both tailgate opening and closing durations can be set for different usage scenarios, further improving the flexibility of controlling the tailgate opening and closing durations.

[0008] In combination with the first aspect, in some possible implementations, the target control duration of the vehicle tailgate is determined based on the target usage scenario, including: when the target usage scenario is a rescue scenario, the first control duration is determined as the target control duration of the vehicle tailgate; when the target usage scenario is a travel scenario, the second control duration is determined as the target control duration of the vehicle tailgate; when the target usage scenario is an exhibition scenario, the third control duration is determined as the target control duration of the vehicle tailgate; wherein the first control duration is less than the second control duration, and the second control duration is less than the third control duration.

[0009] In the above technical solution, this application also proposes that when the target usage scenario is an emergency scenario, the first control duration is determined as the target control duration of the vehicle tailgate; when the target usage scenario is a travel scenario, the second control duration is determined as the target control duration of the vehicle tailgate; and when the target usage scenario is an exhibition scenario, the third control duration is determined as the target control duration of the vehicle tailgate. This allows for different usage scenarios to determine target control durations corresponding to the usage scenarios, making the determination of control durations more flexible. In addition, considering the actual requirements for the control duration of the vehicle tailgate in the emergency scenario, the travel scenario, and the exhibition scenario, it is proposed that the first control duration in the emergency scenario is less than the second control duration in the travel scenario, and the second control duration in the travel scenario is less than the third control duration in the exhibition scenario. The determined control duration of the vehicle tailgate can meet the requirements of the vehicle's current usage scenario for the speed of opening or closing the vehicle tailgate.

[0010] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, when the target control time is the tailgate opening time, the tailgate opening time includes the target unlocking time and the opening drive time, the opening drive time in the first control time is less than the opening drive time in the second control time, and the opening drive time in the second control time is less than the opening drive time in the third control time; when the target control time is the tailgate closing time, the tailgate closing time includes the target locking time and the closing drive time, the closing drive time in the first control time is less than the closing drive time in the second control time, and the opening drive time in the second control time is less than the closing drive time in the third control time.

[0011] In the above technical solution, considering that the tailgate opening process includes the tailgate lock unlocking process and the tailgate opening drive process; and the tailgate closing process includes the tailgate closing drive process and the tailgate lock locking process, different control durations can be set for the tailgate lock unlocking process, unlocking process, and tailgate opening drive process and closing drive process. This application also proposes that when the target control duration is the tailgate opening duration, the tailgate opening duration includes the target unlocking duration and the opening drive duration; when the target control duration is the tailgate closing duration, the tailgate closing duration includes the target locking duration and the closing drive duration. This further increases the flexibility of setting the target control duration of the vehicle tailgate to meet the requirements for vehicle tailgate control duration in different usage scenarios.

[0013] In the above technical solution, the present application also proposes two methods of identifying that the target usage scenario is a rescue scenario, including identifying the collected vehicle cabin image. When it is detected that the vehicle cabin image includes features indicating that the passengers are in need of rescue, it indicates that the vehicle tailgate may need to be opened or closed at a faster speed, that is, the vehicle's current target usage scenario is determined to be a rescue scenario; and / or, obtaining the vehicle's navigation route. When the navigation destination of the navigation route is a hospital, it indicates that the current vehicle may be used to send passengers in need of rescue to the hospital for rescue, that is, the vehicle's current target usage scenario is determined to be a rescue scenario; automatic recognition of the rescue scene and automatic adjustment of the target control time can be achieved, thereby improving the timeliness of adjusting the opening or closing speed of the vehicle's tailgate.

[0014] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the vehicle tailgate includes an upper tailgate and a lower tailgate, the upper tailgate and the lower tailgate are in an upper and lower opening type, and the upper tailgate and the lower tailgate are opened and closed at the same time; when the target control time is the tailgate opening time, the tailgate opening time is determined by the maximum value of the upper tailgate opening time and the lower tailgate opening time; when the target control time is the tailgate closing time, the tailgate closing time is determined by the maximum value of the upper tailgate closing time and the lower tailgate closing time.

[0015] In the above technical solution, the present application proposes a vehicle tailgate structure comprising an upper tailgate and a lower tailgate, the upper tailgate and the lower tailgate are in an upper and lower opening type, and the upper tailgate and the lower tailgate can be opened and closed at the same time; under this structure, if the target control time is the tailgate opening time, the tailgate opening time is determined by the maximum value of the upper tailgate opening time and the lower tailgate opening time; if the target control time is the tailgate closing time, the tailgate closing time is determined by the maximum value of the upper tailgate closing time and the lower tailgate closing time; a method for determining a target control time is provided for the above structure to ensure that the setting of the target control time matches the above vehicle tailgate structure.

[0017] In the above technical solution, the present application proposes a vehicle tailgate structure comprising an upper tailgate and a lower tailgate, the upper tailgate and the lower tailgate are in an upper and lower split-opening type, and the upper tailgate and the lower tailgate have an opening and closing sequence; under this structure, if the target control time is the tailgate opening time, the tailgate opening time is determined by the sum of the opening time of the upper tailgate and the opening time of the lower tailgate; if the target control time is the tailgate closing time, the tailgate closing time is determined by the sum of the closing time of the upper tailgate and the closing time of the lower tailgate; a method for determining a target control time is provided for the above structure to ensure that the setting of the target control time matches the above vehicle tailgate structure.

[0019] In the above technical solution, considering that controlling the vehicle tailgate to open or close with different durations requires determining different voltages, the present application also proposes that when a target control instruction for the vehicle tailgate is received, the target control voltage of the corresponding drive component is determined based on the determined target control duration, and based on the target control voltage, the drive component is controlled to change the tailgate state of the vehicle tailgate; and it is realized that the vehicle tailgate is controlled to open or close with different target control durations according to different target control voltages.

[0044] 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.

[0045] 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.

[0046] Figure 1 FIG1 is a schematic flow chart of a vehicle tailgate control method provided in an embodiment of the present application. It should be understood that the method can be applied to vehicles.

[0047] For example, Figure 1 As shown, the method 100 includes:

[0048] Step 101: Identify the current target usage scenario of the vehicle.

[0049] To facilitate users carrying items while using the vehicle, a trunk is typically provided at the rear of the vehicle. Items can be stored in the trunk by opening the tailgate. Users can control the automatic opening and closing of the tailgate by triggering the relevant tailgate controls or through remote commands. However, the opening and closing duration of the tailgate is generally fixed, and when the vehicle is used in different scenarios, users have different requirements for the opening and closing duration of the tailgate. Therefore, to meet users' requirements for the opening and closing duration of the tailgate in different usage scenarios, this embodiment sets different opening and closing durations for different vehicle usage scenarios. During actual vehicle use, the vehicle can identify the current target usage scenario and select the opening and closing duration that is suitable for the current target usage scenario to control the opening and closing of the tailgate.

[0050] Optionally, the target usage scenario can be pre-configured, or can be set, added, or deleted by the user. Exemplary, the target usage scenario can include a normal scene, a welcoming scene, a travel scene, an exhibition scene, or a rescue scene.

[0051] Optionally, for the method of identifying the target usage scenario of the vehicle: images of the interior or surroundings of the vehicle can be collected and features of the images can be recognized to determine the target usage scenario; or, the target usage scenario can be determined based on the location information of the vehicle by obtaining the location information; or, after the user sets the usage scenario through the vehicle's central control screen or voice, the vehicle's usage scenario setting information is obtained to determine the vehicle's current target usage scenario.

[0052] For example, when it is detected that there are items such as luggage, camping equipment, etc. inside the vehicle, the current target usage scenario of the vehicle is determined to be a travel scenario; if it is detected that the current vehicle is parked at a vehicle sales venue or an auto show venue, the current target usage scenario is determined to be an exhibition scenario.

[0053] Step 102: Based on the target usage scenario, determine the target control duration of the vehicle tailgate. The target control duration includes at least one of the tailgate opening duration and the tailgate closing duration. The tailgate opening duration indicates the time required to control the vehicle tailgate from a closed state to an open state. The tailgate closing duration indicates the time required to control the vehicle tailgate from an open state to a closed state.

[0054] After the target usage scenario of the vehicle is identified, the target control duration of the vehicle tailgate needs to be determined based on the correspondence between the target usage scenario and the opening and closing duration of the vehicle tailgate to meet the tailgate opening and closing requirements of the current target usage scenario.

[0055] The target control duration includes at least one of a tailgate opening duration and a tailgate closing duration. The tailgate opening duration refers to the time required to control the vehicle tailgate from a closed state to an open state. The tailgate closing duration refers to the time required to control the vehicle tailgate from an open state to a closed state.

[0056] Optionally, the open state of the vehicle tailgate may be a state in which the vehicle tailgate reaches a position corresponding to a maximum opening angle, or a state in which the vehicle tailgate reaches a position corresponding to a preset angle.

[0057] During the process of setting the target control time, different tailgate opening time periods can be set for different target usage scenarios, that is, the tailgate opening time period changes with different usage scenarios, while the tailgate closing time period remains the same in all usage scenarios; different tailgate closing time periods can also be set for different target usage scenarios, that is, the tailgate closing time period changes with different usage scenarios, while the tailgate opening time period remains the same in all usage scenarios; different tailgate opening time periods and different tailgate closing time periods can also be set for different target usage scenarios, that is, both the tailgate opening time period and the tailgate closing time period change with different usage scenarios.

[0058] For example, different tailgate opening durations are set for different target usage scenarios, and the tailgate closing duration can be set to a fixed duration. The relationship between the target usage scenarios and the tailgate opening duration and the tailgate closing duration is shown in Table 1.

[0059] Table 1

[0060] Tailgate opening time Tailgate closing time Rescue scene 8s 10s Travel scene 12s 10s Exhibition scene 16s 10s … … …

[0061] As shown in Table 1, the tailgate closing time is fixed at 10 seconds; the tailgate opening time corresponding to the rescue scenario is 8 seconds; the tailgate opening time corresponding to the travel scenario is 12 seconds; and the tailgate opening time corresponding to the exhibition scenario is 16 seconds.

[0062] For example, different tailgate closing durations are set for different target usage scenarios, and the tailgate opening duration can be set to a fixed duration. The relationship between the target usage scenarios and the tailgate opening duration and tailgate closing duration is shown in Table 2.

[0063] Table 2

[0064] Tailgate opening time Tailgate closing time Rescue scene 10s 8s Travel scene 10s 12s Exhibition scene 10s 16s … … …

[0065] As shown in Table 2, the tailgate opening time is fixed at 10 seconds; the tailgate closing time corresponding to the rescue scenario is 8 seconds; the tailgate closing time corresponding to the travel scenario is 12 seconds; and the tailgate closing time corresponding to the exhibition scenario is 16 seconds.

[0066] For example, different tailgate opening durations and different tailgate closing durations are set for different target usage scenarios. The relationship between the target usage scenarios and the tailgate opening durations and tailgate closing durations is shown in Table 3.

[0067] Table 3

[0068] Tailgate opening time Tailgate closing time Rescue scene 8s 6s Travel scene 12s 10s Exhibition scene 16s 16s … … …

[0069] As shown in Table 3, the tailgate opening time corresponding to the rescue scenario is 8 seconds, and the tailgate closing time is 6 seconds; the tailgate opening time corresponding to the travel scenario is 12 seconds, and the tailgate closing time is 12 seconds; the tailgate opening time corresponding to the exhibition scenario is 16 seconds, and the tailgate closing time is 16 seconds.

[0070] Optionally, when the target control duration includes the tailgate opening duration and the tailgate closing duration, in the same target usage scenario, the tailgate opening duration and the tailgate closing duration can be set to the same duration or different durations.

[0071] For example, in an emergency scenario, the tailgate opening time and the tailgate closing time may both be set to 8 seconds; or the tailgate opening time may be set to 8 seconds and the tailgate closing time may be set to 6 seconds.

[0072] Step 103 : upon receiving a target control instruction for the vehicle tailgate, controlling the vehicle tailgate based on the target control duration, wherein the target control instruction is used to change a tailgate state of the vehicle tailgate, wherein the tailgate state includes an open state or a closed state.

[0073] Among them, the target control instruction is used to change the tailgate state of the vehicle's tailgate. The target control instruction may include a target opening instruction and a target closing instruction. The target opening instruction may be an instruction to control the opening of the upper tailgate, or an instruction to control the opening of the lower tailgate, or an instruction to control the opening of both the upper and lower tailgates at the same time; the target closing instruction may be an instruction to control the closing of the upper tailgate, or an instruction to control the closing of the lower tailgate, or an instruction to control the closing of both the upper and lower tailgates at the same time.

[0074] After determining the target control duration of the vehicle tailgate, if a target control instruction for the vehicle tailgate is received, the tailgate state of the vehicle tailgate is changed according to the target control duration, and the tailgate state includes an open state or a closed state.

[0075] If a target opening instruction for the vehicle tailgate is received, the vehicle tailgate is controlled from a closed state to an open state based on the tailgate opening time; if a target closing instruction for the vehicle tailgate is received, the vehicle tailgate is controlled from an open state to a closed state based on the tailgate closing time.

[0076] Optionally, the target control command for the vehicle tailgate can be triggered by the vehicle tailgate switch, voice control, remote control key, mobile phone APP or Bluetooth control.

[0077] In summary, this embodiment provides a vehicle tailgate control method: by identifying the vehicle's current target usage scenario, a target tailgate control duration corresponding to the target usage scenario is determined. Upon receiving a target tailgate control instruction, the vehicle tailgate is controlled based on the determined target control duration, thereby changing the tailgate state of the vehicle tailgate. This method dynamically adjusts the tailgate control duration according to the vehicle's target usage scenario, ensuring that the target tailgate control duration meets the needs of different usage scenarios and improving the flexibility of controlling the tailgate opening and closing duration. Furthermore, the target control duration includes at least one of a tailgate opening duration and a tailgate closing duration. Different tailgate opening durations, different tailgate closing durations, or both can be set for different usage scenarios, further improving the flexibility of controlling the tailgate opening and closing durations.

[0078] The rear space of the vehicle can be used not only for luggage storage but also for passengers to board and exit the vehicle by opening the tailgate in certain vehicles. For different usage scenarios, the vehicle can be pre-configured with tailgate control durations corresponding to the usage scenario to meet the requirements for tailgate opening and closing time in different usage scenarios.

[0079] Figure 2 FIG1 is a schematic flow chart of another vehicle tailgate control method provided by an embodiment of the present application. It should be understood that the method can be applied to vehicles.

[0080] For example, Figure 2 As shown, the method 200 includes:

[0081] Step 201: Identify the current target usage scenario of the vehicle.

[0082] The vehicle is pre-configured with three usage scenarios: emergency, travel, and exhibition. Target control durations corresponding to each scenario are also provided. To adapt the target control durations, corresponding scene recognition methods are provided for each target usage scenario to determine the vehicle's current target usage scenario. In one possible implementation, the method for identifying the vehicle's current target usage scenario as an emergency may include at least one of the following:

[0083] Method 1: Recognize the collected vehicle cabin image; when it is detected that the vehicle cabin image includes target features, determine that the vehicle's current target usage scenario is a rescue scenario, and the target features are used to indicate that the passengers have characteristics of rescue needs.

[0084] When there are injured people, pregnant women, elderly people, and other people in need of medical treatment in a vehicle, if the tailgate is not opened or closed in a timely manner, it will affect the ability of these people to get on and off the vehicle, delaying rescue time. Therefore, the tailgate needs to be able to open or close quickly. To determine whether the people in the vehicle need medical treatment, the vehicle cabin image can be identified by whether it contains specific features to determine whether the current use scenario is a medical treatment scenario. In one possible implementation, the vehicle cabin image is captured by an in-vehicle camera and the captured vehicle cabin image is identified. When the vehicle cabin image is detected to contain target features, the vehicle's current target use scenario is determined to be a medical treatment scenario.

[0085] For example, the target feature may be a specific object feature (eg, a pregnant woman feature, an injured patient feature), or a specific device feature (eg, a medical device), etc.

[0086] Optionally, the vehicle cabin image can be identified through a target recognition model; when training the target recognition model, a variety of sample images containing target features can be collected, and the feature recognition model can be trained based on the multiple image information, so that the feature recognition model has the ability to identify whether the vehicle cabin image includes the target features.

[0087] Method 2: obtaining the navigation route of the vehicle; when the navigation destination of the navigation route is a hospital, determining that the current target usage scenario of the vehicle is a rescue scenario.

[0088] When a vehicle is navigating a route and the navigation destination is a hospital, the vehicle may be in a scenario requiring emergency medical care. In one possible implementation, the vehicle's navigation route can be obtained, and when the navigation destination is a hospital, the vehicle's current target usage scenario can be determined as an emergency medical care scenario.

[0089] Method three: In order to improve the accuracy of emergency scene recognition, the vehicle's navigation route is obtained and the vehicle cabin image is recognized; when the navigation destination is a hospital and the vehicle cabin image contains target features, the vehicle's current target usage scenario is determined to be an emergency scene.

[0090] Optionally, when the vehicle is used in a rescue scenario, the user can set the vehicle's current target usage scenario to a rescue scenario through voice or input operations, and the corresponding vehicle can recognize that the vehicle's current target usage scenario is a rescue scenario.

[0091] In one possible implementation, a method for identifying that the current target usage scenario of the vehicle is a travel scenario may include at least one of the following:

[0092] Method 1: Obtain a luggage compartment image of the vehicle's luggage compartment position; identify the luggage compartment image, and if the luggage compartment image contains travel items such as suitcases and camping equipment, determine the vehicle's current target usage scenario as a travel scenario.

[0093] Method 2: obtaining an image of the vehicle's surroundings; identifying the image of the vehicle's surroundings, and when it is identified that the image of the vehicle's surroundings contains travel supplies, or that the vehicle is at a travel location, determining the vehicle's current target usage scenario as a travel scenario.

[0094] Method three: in response to the user setting the target usage scenario to a travel scenario, determining that the current target usage scenario of the vehicle is a travel scenario.

[0095] In one possible implementation, a method for identifying that the current target usage scenario of the vehicle is an exhibition scenario may include at least one of the following:

[0096] Method 1: Acquire an image of the vehicle's surroundings; recognize the image of the vehicle's surroundings, and when it is recognized that the image of the vehicle's surroundings contains features indicating that the vehicle is in an exhibition venue, determine that the current target usage scenario is an exhibition scenario.

[0097] Method 2: obtaining the location information of the vehicle. If the location information indicates that the vehicle is at a car sales location or a location where a car show is being held, determining that the current target usage scenario is an exhibition scenario.

[0098] Method three: in response to the user setting the target usage scenario to an exhibition scenario, determining that the current target usage scenario of the vehicle is an exhibition scenario.

[0099] Step 202: When the target usage scenario is an emergency scenario, the first control duration is determined as the target control duration of the vehicle tailgate.

[0100] Different vehicle usage scenarios require different tailgate opening and closing speeds. Therefore, different tailgate control durations can be set for different target usage scenarios. The vehicle is pre-configured with a correspondence between vehicle usage scenarios and control durations. Table 4 shows the correspondence between usage scenarios and control durations.

[0101] Table 4

[0102] Usage scenarios Control duration Rescue scene First control duration Travel scene Second control time Exhibition scene The third control time … …

[0103] As shown in Table 4, the control duration for the rescue scenario is the first control duration, the control duration for the travel scenario is the second control duration, and the control duration for the exhibition scenario is the third control duration. Considering the time constraints in the rescue scenario, a shorter control duration is required to facilitate faster boarding and disembarking for users. In the travel scenario, the tailgate opening and closing duration requirements are lower, so a moderate control duration can be determined. In the exhibition scenario, a longer control duration can be set to demonstrate the tailgate's operation to the user. Therefore, the first control duration for the rescue scenario is set shorter than the second control duration for the travel scenario, and the second control duration for the travel scenario is set shorter than the third control duration for the exhibition scenario.

[0104] When the target usage scenario is an emergency rescue scenario, the tailgate needs to be opened and closed at a faster speed to avoid wasting time. In one possible implementation, the emergency rescue scenario corresponds to a first control duration. When the target usage scenario is an emergency rescue scenario, the first control duration is determined as the target control duration to control the tailgate to open or close faster.

[0105] For example, the first control time can be set to 8 seconds. When it is identified that the target usage scenario is a rescue scenario, the target control time of the vehicle tailgate is 8 seconds.

[0106] To facilitate tailgate opening in emergencies, the system can preemptively control the tailgate's opening upon detecting an ambulance scenario, facilitating boarding. In one possible implementation, upon detecting an ambulance scenario, the system obtains the user's speed within a preset range as they approach the tailgate. If the speed exceeds a threshold, the system automatically controls the tailgate's opening, ensuring it's already open by the time the user reaches the tailgate, further reducing boarding time in ambulance scenarios.

[0107] For example, when the vehicle is used as an ambulance, an environmental image around the tailgate of the vehicle is obtained; when the environmental image contains features such as medical equipment (stretchers, wheelchairs, etc.), medical staff, injured patients, pregnant women, etc., the movement speed of users approaching the tailgate of the vehicle within 5 meters around the vehicle is further obtained; if the user's movement speed is detected to be greater than the speed threshold, indicating that the current scene is an emergency rescue scene, the tailgate of the vehicle is controlled to open automatically in advance.

[0108] Optionally, after recognizing that a user is getting on the vehicle, the tailgate of the vehicle can be automatically controlled to close in advance without the user having to manually close the tailgate, so as to further shorten the time to get on the vehicle in an ambulance scenario.

[0109] In an emergency scenario, in addition to opening the tailgate in advance when the user boards the vehicle to shorten the boarding time, the tailgate can also be opened in advance when the vehicle is detected to be approaching an emergency location, making it easier for the user to exit the vehicle and saving time. In one possible implementation, if the target usage scenario of the vehicle is identified as an emergency and the navigation route indicates that the distance to the emergency location remains within the target distance, the tailgate is controlled to open in advance.

[0110] For example, when the destination of the vehicle's navigation route is identified as an emergency site, or when features such as injured persons, pregnant women, medical staff, or medical equipment are identified inside the vehicle, or when the vehicle's target usage scenario is set to an emergency scene, if it is detected that the vehicle is 5 meters away from the emergency site, the vehicle's tailgate is controlled to open automatically, so that the vehicle's tailgate is opened in advance when the vehicle reaches its destination.

[0111] Step 203 : When the target usage scenario is a travel scenario, the second control duration is determined as the target control duration of the vehicle tailgate.

[0112] When the vehicle is in a travel scenario, the tailgate opening and closing time requirements are not high. A moderate control duration can be set based on the user's daily habits. In one possible implementation, the travel scenario corresponds to a second control duration. When the target usage scenario is travel, the second control duration is used as the target tailgate control duration to control the tailgate to open or close at a moderate speed.

[0113] Exemplarily, the second control duration may be set to 12 seconds. When it is identified that the target usage scenario is a travel scenario, the target control duration of the vehicle tailgate is determined to be 12 seconds.

[0114] Step 204 : When the target usage scenario is an exhibition scenario, the third control duration is determined as the target control duration of the vehicle tailgate.

[0115] When a vehicle dealer is demonstrating a vehicle to a user, they may tend to show the operating process of various vehicle components. Therefore, the tailgate can be controlled to open or close at a slower speed. In one possible implementation, the exhibition scenario corresponds to the third control duration. If the target usage scenario is an exhibition scenario, the third control duration is used as the target tailgate control duration to control the tailgate to open or close at a moderate speed.

[0116] Exemplarily, the third control time length may be set to 16 seconds. When it is identified that the target usage scenario is an exhibition scenario, the target control time length of the vehicle tailgate is 16 seconds.

[0117] Considering that the target control duration includes at least one of the tailgate opening duration and the tailgate closing duration; and that the tailgate opening process includes the tailgate lock unlocking process and the tailgate opening drive process, and the tailgate closing process includes the tailgate lock locking process and the tailgate closing drive process; to further enhance the flexibility of setting the tailgate control duration, different control durations can be set for the tailgate lock unlocking process, the tailgate unlocking process, and the tailgate opening drive process and the tailgate closing drive process. When the target control duration is the tailgate opening duration, the tailgate opening duration includes a target unlocking duration and an opening drive duration. During the tailgate opening duration setting process, different opening drive durations can be set only for different usage scenarios, i.e., the opening drive duration varies with different usage scenarios, while the target unlocking duration remains the same in different usage scenarios. Alternatively, different target unlocking times and different opening drive durations can be set for different usage scenarios, i.e., both the opening drive duration and the target unlocking time vary with different usage scenarios.

[0118] Among them, the target unlocking time refers to the time it takes for the controller to control the release of the tailgate lock pawl; the opening drive time refers to the time it takes from the tailgate lock to unlocking to the vehicle tailgate opening to the preset opening angle, or the time it takes from the tailgate lock to unlocking to the vehicle tailgate opening to the fully open position.

[0119] When the opening drive duration changes with different usage scenarios, while the target unlocking duration is the same in different usage scenarios, in order to adapt to the door opening duration requirements in different target usage scenarios, the opening drive duration in the first control duration is set to be smaller than the opening drive duration in the second control duration, and the opening drive duration in the second control duration is set to be smaller than the opening drive duration in the third control duration.

[0120] For example, the target control duration is the tailgate opening duration. The corresponding relationship between the usage scenario and the target unlocking duration, opening driving duration, and tailgate opening duration is shown in Table 5.

[0121] Table 5

[0122] Usage scenarios Target unlocking time Drive start time Tailgate opening time Rescue scene 1s 5s 6s Travel scene 1s 7s 8s Exhibition scene 1s 9s 10s … … … …

[0123] As shown in Table 5, the target unlocking time is fixed at 1s. The corresponding opening driving time for the rescue scenario is 5s, so the tailgate opening time is 6s. The corresponding opening driving time for the travel scenario is 7s, so the tailgate opening time is 8s. The corresponding opening driving time for the exhibition scenario is 9s, so the tailgate opening time is 10s.

[0124] In the case of setting different target unlocking times and different start-up driving times for different usage scenarios, the target unlocking time in the first control time is less than the target unlocking time in the second control time, and the target unlocking time in the second control time is less than the target unlocking time in the third control time; the start-up driving time in the first control time is less than the start-up driving time in the second control time, and the start-up driving time in the second control time is less than the start-up driving time in the third control time.

[0125] For example, the target control duration is the tailgate opening duration. When different target unlocking durations and different opening drive durations are set for different usage scenarios, the corresponding relationship between the usage scenarios and the target unlocking durations, opening drive durations, and tailgate opening durations is shown in Table 6.

[0126] Table 6

[0127] Usage scenarios Target unlocking time Drive start time Tailgate opening time Rescue scene 0.5s 5s 5.5s Travel scene 1s 7s 8s Exhibition scene 1.5s 9s 10.5s … … … …

[0128] As shown in Table 6, the target unlocking time for the rescue scenario is 0.5s, the opening driving time is 5s, and the tailgate opening time is 5.5s; the target unlocking time for the travel scenario is 1s, the opening driving time is 7s, and the tailgate opening time is 8s; the target unlocking time for the exhibition scenario is 1.5s, the opening driving time is 9s, and the tailgate opening time is 10.5s.

[0129] When the target control time is the tailgate closing time, the tailgate closing time includes the target locking time and the closing drive time; in the process of setting the tailgate closing time, different closing drive times can be set only for different usage scenarios, that is, the closing drive time changes with different usage scenarios, and the target locking time is the same in different usage scenarios; different target locking times and different closing drive times can also be set for different usage scenarios, that is, both the closing drive time and the target locking time change with different usage scenarios.

[0130] Among them, the target locking time refers to the time when the controller controls the tailgate lock pawl to be locked; the closing drive time refers to the time when the vehicle tailgate closes from the preset opening angle to the fully closed position.

[0131] When different closing drive durations are set only for different usage scenarios, a fixed target locking duration is adopted, the closing drive duration in the first control duration is less than the closing drive duration in the second control duration, and the opening drive duration in the second control duration is less than the closing drive duration in the third control duration.

[0132] For example, the target control duration is the tailgate closing duration. When different closing drive durations are set for different usage scenarios, the corresponding relationship between the usage scenarios and the target locking duration, closing drive duration, and tailgate closing duration is shown in Table 7.

[0133] Table 7

[0134]

[0135]

[0136] As shown in Table VII, the target locking time is fixed at 1s. The closing actuation time corresponding to the rescue scenario is 5s, so the tailgate closing time is 6s. The closing actuation time corresponding to the travel scenario is 7s, so the tailgate closing time is 8s. The closing actuation time corresponding to the exhibition scenario is 9s, so the tailgate closing time is 10s.

[0137] When different target locking times and different closing drive times are set for different usage scenarios, the target locking time in the first control time is smaller than the target locking time in the second control time, and the target locking time in the second control time is smaller than the target locking time in the third control time; the closing drive time in the first control time is smaller than the closing drive time in the second control time, and the closing drive time in the second control time is smaller than the closing drive time in the third control time.

[0138] For example, the target control duration is the tailgate closing duration. When different target locking durations and different closing drive durations are set for different usage scenarios, the corresponding relationship between the usage scenarios and the target locking durations, closing drive durations, and tailgate closing durations is shown in Table 8.

[0139] Table 8

[0140] Usage scenarios Target lock duration Turn off the drive time Tailgate closing time Rescue scene 0.5s 5s 5.5s Travel scene 1s 7s 8s Exhibition scene 1.5s 9s 10.5s … … … …

[0141] As shown in Table 8, the target locking time for the rescue scenario is 0.5s, and the closing drive time is 5s, so the tailgate closing time is 5.5s; the target locking time for the travel scenario is 1s, and the closing drive time is 7s, so the tailgate closing time is 8s; the target locking time for the exhibition scenario is 1.5s, and the closing drive time is 9s, so the tailgate closing time is 10.5s.

[0142] Step 205 : upon receiving a target control instruction for the vehicle tailgate, determining a target control voltage of the drive component based on a target control duration.

[0143] When controlling the opening or closing of a vehicle's tailgate, the voltage of the tailgate drive assembly is adjusted to achieve different opening or closing times. In one possible embodiment, different control voltages are set for different control durations. During use, when a target control command for the vehicle's tailgate is received, a target control voltage for the drive assembly is determined based on the target control duration corresponding to the vehicle's current target usage scenario, and the tailgate is then driven and controlled by the target control voltage.

[0144] For example, when it is identified that the target usage scenario of the vehicle is an exhibition scenario, upon receiving a target control instruction for the vehicle tailgate sent by the user via a remote control, the vehicle tailgate is controlled to be opened or closed with a target control voltage corresponding to the target control duration in the exhibition scenario.

[0145] Optionally, when it is identified that the target usage scenario of the vehicle is a rescue scenario and the situation is urgent, the vehicle automatically sends a target opening instruction or a target closing instruction to the tailgate of the vehicle to control the vehicle to open or close in advance; after receiving the target opening instruction or the target closing instruction, based on the target control time in the rescue scenario, the target control voltage of the drive component is determined to control the tailgate of the vehicle to open or close quickly.

[0146] For example, when the vehicle is currently functioning as an ambulance and recognizes that medical personnel or injured persons carrying medical equipment are approaching the tailgate of the vehicle at a relatively fast speed, the vehicle automatically sends a target opening instruction to the tailgate of the vehicle. After receiving the target opening instruction, the tailgate of the vehicle determines the target control voltage based on the target control duration corresponding to the rescue scenario, and controls the opening of the tailgate of the vehicle in advance.

[0147] Step 206 : Based on the target control voltage, change the tailgate state of the vehicle tailgate through the driving component.

[0148] After determining the target control voltage of the driving component, the driving component is controlled to change the tailgate state of the vehicle tailgate by adopting target control voltages of different magnitudes, thereby realizing opening or closing of the vehicle tailgate.

[0149] In this embodiment, the present application further proposes that when the target usage scenario is an emergency rescue scenario, the first control duration is determined as the target control duration of the vehicle tailgate; when the target usage scenario is a travel scenario, the second control duration is determined as the target control duration of the vehicle tailgate; and when the target usage scenario is an exhibition scenario, the third control duration is determined as the target control duration of the vehicle tailgate. This allows for determining target control durations corresponding to different usage scenarios, making the determination of control durations more flexible. Furthermore, considering the actual requirements for the control duration of the vehicle tailgate in the emergency rescue scenario, the travel scenario, and the exhibition scenario, it is proposed that the first control duration in the emergency rescue scenario is less than the second control duration in the travel scenario, and that the second control duration in the travel scenario is less than the third control duration in the exhibition scenario. The determined control duration of the vehicle tailgate can meet the requirements for the opening or closing speed of the vehicle tailgate in the current usage scenario of the vehicle.

[0150] Secondly, considering that the tailgate opening process includes the tailgate lock unlocking process and the tailgate opening drive process; and the tailgate closing process includes the tailgate closing drive process and the tailgate lock locking process, different control durations can be set for the tailgate lock unlocking process, unlocking process, and tailgate opening drive process and closing drive process. This application also proposes that when the target control duration is the tailgate opening duration, the tailgate opening duration includes the target unlocking duration and the opening drive duration; when the target control duration is the tailgate closing duration, the tailgate closing duration includes the target locking duration and the closing drive duration. This further increases the flexibility of setting the target control duration of the vehicle tailgate to meet the requirements for vehicle tailgate control duration in different usage scenarios.

[0151] In addition, the present application also proposes two methods of identifying that the target usage scenario is a rescue scenario, including identifying the collected vehicle cabin image, and when it is detected that the vehicle cabin image includes features indicating that the passengers are in need of rescue, it indicates that the vehicle tailgate may need to be opened or closed at a faster speed, that is, the vehicle's current target usage scenario is determined to be a rescue scenario; and / or, obtaining the vehicle's navigation route, when the navigation destination of the navigation route is a hospital, it indicates that the current vehicle may be used to send passengers in need of rescue to the hospital for rescue, that is, the vehicle's current target usage scenario is determined to be a rescue scenario; automatic identification of the rescue scene and automatic adjustment of the target control time can be achieved, thereby improving the timeliness of adjusting the opening or closing speed of the vehicle's tailgate.

[0152] Finally, considering that controlling the vehicle tailgate to open or close with different durations requires determining different voltages, the present application also proposes that when a target control instruction for the vehicle tailgate is received, the target control voltage of the corresponding drive component is determined based on the determined target control duration, and based on the target control voltage, the drive component is controlled to change the tailgate state of the vehicle tailgate; and it is achieved that the vehicle tailgate is controlled to open or close with different target control durations according to different target control voltages.

[0153] In order to enhance the diversity of tailgate functions and meet the personalized needs of different users, the present application proposes a vehicle tailgate that opens up and down, and the vehicle tailgate includes an upper tailgate and a lower tailgate; wherein, one structure can realize the simultaneous opening or closing of the upper tailgate and the lower tailgate, and in another structure, the upper tailgate and the lower tailgate have an opening and closing sequence; under different vehicle tailgate structures, the setting of the tailgate control time may be different. Therefore, for different vehicle tailgate structures, different methods for determining the tailgate control time can be adopted to adapt to different vehicle tailgate structures.

[0154] Figure 3 This is a schematic diagram of the structure of an upper tailgate and a lower tailgate provided in an embodiment of the present application. Figure 3 As shown, the upper and lower tailgates can be opened or closed simultaneously. When the upper and lower tailgates are locked, upon receiving an open command, the upper and lower tailgates can be opened simultaneously. Alternatively, upon receiving a lower tailgate open command, the lower tailgate is opened; upon receiving an upper tailgate open command, the upper tailgate is opened. Alternatively, when the upper and lower tailgates are open, upon receiving a close command, the upper and lower tailgates can be closed simultaneously. Alternatively, upon receiving a lower tailgate close command, the lower tailgate is closed; upon receiving an upper tailgate close command, the upper tailgate is closed.

[0155] based on Figure 3 The vehicle tailgate structure shown, Figure 4 Schematic diagram of the opening and closing process of a vehicle tailgate provided in an embodiment of the present application. Figure 4 As shown, when the body domain controller 401 receives any electric opening or closing instruction, it transmits the information to the tailgate controller 402, and upon determining that the surrounding conditions are met, it executes the simultaneous opening of the upper tailgate and the lower tailgate\or the simultaneous closing of the upper tailgate and the lower tailgate.

[0156] Figure 5 This is a flow chart of a vehicle tailgate control process provided by an embodiment of the present application. Figure 5As shown, when the upper tailgate and the lower tailgate can be opened and closed at the same time, the scene mode set by the user is obtained. When the electric split tailgate is triggered, the tailgate control unit 501 controls the upper tailgate lock 5011 and the upper tailgate drive structure 5012 to open or close the upper tailgate; and controls the lower tailgate lock 5013 and the lower tailgate drive structure 5014 to open or close the lower tailgate.

[0157] Considering that when a vehicle's tailgate structure includes an upper tailgate and a lower tailgate, and that the upper and lower tailgates can be opened and closed simultaneously, the opening or closing of the upper and lower tailgates do not affect each other. The opening durations of the upper and lower tailgates overlap. Therefore, when the target control duration is the tailgate opening duration, the tailgate opening duration is determined by the maximum of the upper and lower tailgate opening durations. The closing durations of the upper and lower tailgates also overlap. Therefore, when the target control duration is the tailgate closing duration, the tailgate closing duration is determined by the maximum of the upper and lower tailgate closing durations.

[0158] For example, when the target control duration is the tailgate opening duration, and the upper and lower tailgates can be opened and closed simultaneously, the corresponding relationship among the target usage scenario, the upper tailgate opening duration, the lower tailgate opening duration, and the tailgate opening duration is shown in Table 9.

[0159] Table 9

[0160] Tailgate opening time Tailgate opening time Tailgate opening time Rescue scene 4.5s 3.5s 4.5s Travel scene 7s 5s 7s Exhibition scene 9s 7s 9s … … … …

[0161] As shown in Table 9, when the target control duration is the tailgate opening duration and the upper and lower tailgates can be opened and closed simultaneously, in the rescue scenario, the upper tailgate opening duration is 4.5 seconds and the lower tailgate opening duration is 3.5 seconds, so the maximum tailgate opening duration is 4.5 seconds; in the travel scenario, the upper tailgate opening duration is 7 seconds and the lower tailgate opening duration is 5 seconds, so the maximum tailgate opening duration is 7 seconds; in the exhibition scenario, the upper tailgate opening duration is 9 seconds and the lower tailgate opening duration is 7 seconds, so the maximum tailgate opening duration is 9 seconds.

[0162] For example, when the target control duration is the tailgate closing duration, and the upper and lower tailgates can be opened and closed simultaneously, the corresponding relationships among the target usage scenario, the upper tailgate closing duration, the lower tailgate closing duration, and the tailgate closing duration are shown in Table 10.

[0163] Table 10

[0164] Closing time of the tailgate Closing time of the lower tailgate Tailgate closing time Rescue scene 4s 3s 4s Travel scene 6s 4s 4s Exhibition scene 10s 6s 10s … … … …

[0165] As shown in Table 10, when the target control duration is the tailgate closing duration, and the upper and lower tailgates can be opened and closed simultaneously, in the rescue scenario, the upper tailgate closing duration is 4 seconds, and the lower tailgate closing duration is 3 seconds, so the maximum tailgate closing duration is 4 seconds; in the travel scenario, the upper tailgate closing duration is 6 seconds, and the lower tailgate closing duration is 4 seconds, so the maximum tailgate closing duration is 6 seconds; in the exhibition scenario, the upper tailgate closing duration is 10 seconds, and the lower tailgate closing duration is 6 seconds, so the maximum tailgate closing duration is 10 seconds.

[0166] In the above technical solution, the present application proposes a vehicle tailgate structure comprising an upper tailgate and a lower tailgate, the upper tailgate and the lower tailgate are in an upper and lower opening type, and the upper tailgate and the lower tailgate can be opened and closed at the same time; under this structure, if the target control time is the tailgate opening time, the tailgate opening time is determined by the maximum value of the upper tailgate opening time and the lower tailgate opening time; if the target control time is the tailgate closing time, the tailgate closing time is determined by the maximum value of the upper tailgate closing time and the lower tailgate closing time; a method for determining a target control time is provided for the above structure to ensure that the setting of the target control time matches the above vehicle tailgate structure.

[0167] Figure 6 This is a schematic diagram of the structure of another upper tailgate and lower tailgate provided in an embodiment of the present application. Figure 6 As shown. The upper tailgate has an outer ledge and the lower tailgate has an inner ledge. When both are locked, the outer ledge overlaps the inner ledge (that is, the upper tailgate covers the lower tailgate). Upon receiving any open command, the upper tailgate must be opened before the lower tailgate can be opened. When both are open, upon receiving any close command, the lower tailgate must be closed before the upper tailgate can be closed.

[0168] based on Figure 6 The vehicle tailgate structure shown, Figure 7 This is another schematic diagram of the opening and closing process of a vehicle tailgate provided by an embodiment of the present application. Figure 7 As shown, both the upper tailgate and the lower tailgate are in the closed state. When the body domain controller 701 receives any electric opening instruction, it transmits information to the upper tailgate controller 702 and the lower tailgate controller 703. The upper tailgate controller 702 determines and executes to open the upper tailgate. When the upper tailgate is fully opened, the lower tailgate controller 703 controls to open the lower tailgate. Optionally, both the upper tailgate and the lower tailgate are in the open state. When the body domain controller 701 receives any electric closing instruction, it transmits information to the upper tailgate controller 702 and the lower tailgate controller 703. When the lower tailgate controller 703 controls the lower tailgate to be fully closed, the upper tailgate controller 702 detects the lower tailgate locking signal and then controls the upper tailgate to close.

[0169] Figure 8 This is another flow chart of vehicle tailgate control provided by the embodiment of the present application. Figure 8 As shown, when there is an opening and closing sequence for the upper tailgate and the lower tailgate, the scene mode set by the user is obtained. When the electric split tailgate is triggered, the upper tailgate control unit 801 controls the upper tailgate lock 8011 and the upper tailgate drive structure 8012 to open or close the upper tailgate; the lower tailgate control unit 802 controls the lower tailgate lock 8021 and the lower tailgate drive structure 8022 to open or close the lower tailgate.

[0170] Considering that when a vehicle's tailgate structure includes an upper tailgate and a lower tailgate, and that the upper and lower tailgates have an opening and closing sequence, the lower tailgate can only be opened after the upper tailgate is opened, and the upper tailgate can only be closed after the lower tailgate is closed. Therefore, when the target control duration is the tailgate opening duration, the tailgate opening duration is determined by the sum of the upper tailgate opening duration and the lower tailgate opening duration; when the target control duration is the tailgate closing duration, the tailgate closing duration is determined by the sum of the upper tailgate closing duration and the lower tailgate closing duration.

[0171] For example, when the target control duration is the tailgate opening duration, and the upper tailgate and the lower tailgate have an opening and closing sequence, the corresponding relationship among the target usage scenario, the upper tailgate opening duration, the lower tailgate opening duration, and the tailgate opening duration is shown in Table 11.

[0172] Table 11

[0173] Tailgate opening time Tailgate opening time Tailgate opening time Rescue scene 4.5s 3.5s 8s Travel scene 7s 5s 12s Exhibition scene 9s 7s 16s … … … …

[0174] As shown in Table 11, when the target control duration is the tailgate opening duration and the upper and lower tailgates can be opened and closed simultaneously, in the rescue scenario, the upper tailgate opening duration is 4.5 seconds and the lower tailgate opening duration is 3.5 seconds, so the sum of the upper and lower tailgate opening durations is 8 seconds. In the travel scenario, the upper tailgate opening duration is 7 seconds and the lower tailgate opening duration is 5 seconds, so the sum of the upper and lower tailgate opening durations is 12 seconds. In the exhibition scenario, the upper tailgate opening duration is 9 seconds and the lower tailgate opening duration is 7 seconds, so the sum of the upper and lower tailgate opening durations is 16 seconds.

[0175] For example, when the target control duration is the tailgate closing duration, and the upper tailgate and the lower tailgate have an opening and closing sequence, the corresponding relationship among the target usage scenario, the upper tailgate closing duration, the lower tailgate closing duration, and the tailgate closing duration is shown in Table 12.

[0176] Table 12

[0177]

[0178]

[0179] As shown in Table 12, when the target control duration is the tailgate closing duration, and the upper and lower tailgates have an opening and closing sequence, in the rescue scenario, the upper tailgate closing duration is 4 seconds, and the lower tailgate closing duration is 3 seconds, so the tailgate closing duration is the sum of the upper and lower tailgate closing durations, which is 7 seconds; in the travel scenario, the upper tailgate closing duration is 6 seconds, and the lower tailgate closing duration is 4 seconds, so the tailgate closing duration is the sum of the upper and lower tailgate closing durations, which is 10 seconds; in the exhibition scenario, the upper tailgate closing duration is 10 seconds, and the lower tailgate closing duration is 6 seconds, so the tailgate closing duration is the sum of the upper and lower tailgate closing durations, which is 16 seconds.

[0180] In the above technical solution, the present application proposes a vehicle tailgate structure comprising an upper tailgate and a lower tailgate, the upper tailgate and the lower tailgate are in an upper and lower split-opening type, and the upper tailgate and the lower tailgate have an opening and closing sequence; under this structure, if the target control time is the tailgate opening time, the tailgate opening time is determined by the sum of the opening time of the upper tailgate and the opening time of the lower tailgate; if the target control time is the tailgate closing time, the tailgate closing time is determined by the sum of the closing time of the upper tailgate and the closing time of the lower tailgate; a method for determining a target control time is provided for the above structure to ensure that the setting of the target control time matches the above vehicle tailgate structure.

[0181] During the process of setting the target control time of the vehicle tailgate, the user can set the target control time for different usage scenarios according to their actual needs, and control the vehicle tailgate based on the target control time set by the user to realize the opening and closing of the tailgate.

[0182] Figure 9 FIG1 is a schematic flow chart of another vehicle tailgate control method provided by an embodiment of the present application. It should be understood that the method can be applied to vehicles.

[0183] For example, Figure 9 As shown, the method 900 includes:

[0184] Step 901: responding to an operation of setting a target control duration.

[0185] In order to make the target control time setting of the vehicle tailgate more flexible and meet the user's own needs, the vehicle provides a control time setting interface. The user can set different usage scenarios and the target control time corresponding to different usage scenarios in this setting interface. The corresponding vehicle receives the setting operation of the target control time.

[0186] Optionally, the user can set the target control time through a vehicle-mounted terminal, mobile phone terminal or other portable device; after the user sets the target control time through a mobile phone terminal or other portable device, the mobile phone terminal or other portable device can send the target control time setting instruction to the vehicle.

[0187] Step 902: Based on the setting operation, determine the target control duration corresponding to each target usage scenario.

[0188] After receiving the user's setting operation for the target control time, the vehicle can set the association between each target usage scenario and the target control time based on the setting operation; so that when the vehicle subsequently recognizes the target usage scenario, the target control time associated with the target usage scenario can be used to control the opening or closing of the vehicle tailgate.

[0189] Step 903: Identify the current target usage scenario of the vehicle.

[0190] Step 904: Determine the target control duration of the vehicle tailgate based on the target usage scenario.

[0191] Among them, the target control time includes at least one of the tailgate opening time and the tailgate closing time. The tailgate opening time indicates the time required to control the vehicle tailgate from a closed state to an open state, and the tailgate closing time indicates the time required to control the vehicle tailgate from an open state to a closed state.

[0192] Step 905 : When receiving a target control instruction for the vehicle tailgate, control the vehicle tailgate based on the target control duration.

[0193] The target control instruction is used to change the tailgate state of the vehicle tailgate, where the tailgate state includes an open state or a closed state.

[0194] The implementation of steps 903 to 905 can refer to the above embodiment, and will not be described in detail in this embodiment.

[0195] In this embodiment, in order to make the target control time of the vehicle tailgate more in line with user needs, this application also proposes to determine the corresponding target control time under each target usage scenario in response to the user's setting operation of the target control time; the user can set the target control time for different scenarios according to their own needs, so that the control time of the vehicle tailgate is more in line with user habits, further improving the flexibility of the target control time setting.

[0203] In one possible implementation, the target usage scenario is a rescue scenario, and the identification module 1001 is also used to identify the collected vehicle cabin image; when it is detected that the vehicle cabin image includes target features, it is determined that the vehicle's current target usage scenario is a rescue scenario, and the target features are used to indicate that the passengers have rescue needs; the vehicle's navigation route is obtained; when the navigation destination of the navigation route is a hospital, it is determined that the vehicle's current target usage scenario is a rescue scenario.

[0204] In one possible implementation, the vehicle tailgate includes an upper tailgate and a lower tailgate, the upper tailgate and the lower tailgate are arranged to open and close simultaneously; when the target control duration is the tailgate opening duration, the tailgate opening duration is determined by the maximum value of the upper tailgate opening duration and the lower tailgate opening duration; when the target control duration is the tailgate closing duration, the tailgate closing duration is determined by the maximum value of the upper tailgate closing duration and the lower tailgate closing duration.

[0205] In one possible implementation, the vehicle tailgate includes an upper tailgate and a lower tailgate, the upper tailgate and the lower tailgate are arranged to open and close in an upper and lower direction, and the upper tailgate and the lower tailgate have an opening and closing sequence; when the target control duration is the tailgate opening duration, the tailgate opening duration is determined by the sum of the opening duration of the upper tailgate and the opening duration of the lower tailgate; when the target control duration is the tailgate closing duration, the tailgate closing duration is determined by the sum of the closing duration of the upper tailgate and the closing duration of the lower tailgate.

[0206] In one possible implementation, the control module 1003 is further used to determine the target control voltage of the drive component based on the target control duration when receiving a target control instruction for the vehicle tailgate; and change the tailgate state of the vehicle tailgate through the drive component based on the target control voltage.

[0207] In one possible implementation, the device further includes: a response module for responding to a setting operation of the target control duration; and a second determination module for determining the target control duration corresponding to each target usage scenario based on the setting operation.
