[0002] The existing vehicle tailgate automatically opens by using the sensor at the lower edge of the rear bumper below the vehicle tailgate. When the foot sweeps over the sensor at the lower edge of the rear bumper, the sensor recognizes an effective kicking action, thereby triggering the electric tailgate switch. However, if the user's foot movement is not standard, the user needs to open it manually. When the user's hands are full of items, it will make it difficult to open the vehicle tailgate conveniently. Therefore, the current method of automatically opening the vehicle tailgate has a low recognition accuracy and a poor user interaction experience. Summary of the invention

[0070] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0071] Figure 1 Flow chart of a vehicle tailgate control method in one embodiment of the present application. Figure 1 As shown, the method can be implemented as the following steps S101-S103:

[0072] In step S101, when the distance between the user and the rear tailgate is less than a first preset distance, multiple command acquisition functions including at least a motion sensing function of a specific area, a surround camera function, and a voice receiving function of a specific area are activated to acquire command information input by the user;

[0073] In step S102, it is determined whether at least one of the multiple functions obtains a switch instruction for the rear tailgate;

[0074] In step S103, when at least one of the multiple functions obtains a switch instruction of the rear tailgate, the rear tailgate is controlled to perform an opening / closing operation.

[0075] In the present application, when the distance between the user and the tailgate is less than a first preset distance, a variety of command acquisition functions including at least a motion sensing function for a specific area, a surround camera function, and a voice receiving function for a specific area are activated to obtain the command information input by the user.

[0076] In order to facilitate the legitimate users of the vehicle to open the rear tailgate of the vehicle, when a user to be detected is detected whose distance from the vehicle is less than the second preset distance, the facial information and / or voice information of the user to be detected is collected, wherein the second preset distance is greater than the first preset distance. For example, when it is detected that someone is approaching the vehicle within 3 meters of the vehicle, the facial information and / or voice information of the user to be detected is collected through the camera or microphone of the vehicle. Then, it is determined whether the facial information and / or voice information of the user to be detected is the pre-stored facial information and / or voice information. The specific facial recognition and voice recognition methods are not limited in this application. When the facial information and / or voice information to be detected is the pre-stored facial information and / or voice information, it is determined that the user to be detected is a legitimate user with the rear tailgate opening and closing authority, such as the owner or the owner's family. This improves the safety of the vehicle and avoids frequent monitoring of whether the rear tailgate of the vehicle needs to be opened. When it is determined that a legitimate user is approaching the vehicle, when the distance between the user and the tailgate is less than a first preset distance, for example, when the distance between the user and the vehicle is less than 1 meter, a variety of command acquisition functions including at least a motion sensing function for a specific area, a surround camera function, and a voice receiving function for a specific area are activated to obtain command information output by the user.

[0077] Specifically, the motion sensing function in a specific area can be enabled by turning on the sensors in the specific area, such as the sensor in the rear bumper; the surround camera function can be enabled by turning on the surround camera, such as the 360° surround camera; the voice reception function in a specific area can be enabled by turning on the microphones in the specific area, such as the multiple microphones in the rear bumper area.

[0078] Determine whether there is at least one function among the multiple functions that can obtain the opening and closing instructions of the rear tailgate. In the present application, multiple functions can open or close the tailgate. When one or two functions are unavailable, another function can still ensure that the rear tailgate of the vehicle is opened or closed. Specifically, the command information output by the collected legitimate user, such as the user's footsteps, posture information, and voice information, etc., is compared with the corresponding pre-stored information. For example, different legitimate users can store the footsteps of opening the rear tailgate in advance as the preset footsteps instructions for opening and closing the rear tailgate, such as sweeping across a preset area, or kicking in a preset area, etc.; when the user's footsteps are collected, the collected information is compared with the preset footsteps instructions for opening and closing the rear tailgate. Specifically, the comparison can be performed through image recognition and other technologies. The present application does not limit the comparison method, and then determine whether the current user's footsteps are the preset footsteps instructions for opening and closing the rear tailgate. When there is a legitimate user who has not pre-stored the footstep instruction for opening and closing the rear tailgate, the footstep movement trend of the footstep instruction for opening and closing the rear tailgate of other legitimate users is obtained. When the footstep movement of the current legitimate user is consistent with the footstep movement trend, the footstep movement of the current user is determined to be the preset footstep instruction for opening and closing the rear tailgate. For the preset posture instruction for opening and closing the rear tailgate, the posture information can be stored in advance by the user; or the posture determination algorithm can be obtained through the posture information of opening the door of different users collected by big data. The collected posture information of the legitimate user is compared with the preset posture instruction for opening and closing the rear tailgate. When the similarity with the pre-stored posture information is greater than the preset posture similarity, or the posture determination algorithm obtains the posture information of the current posture as the posture information for opening the rear tailgate of the vehicle, it is determined that the posture information of the current user is the preset posture instruction for opening and closing the rear tailgate. For the preset voice instruction for opening and closing the rear tailgate, it can be a plurality of voice instructions pre-determined by the user. By comparing the voice information of the legitimate user with the plurality of voice instructions, it is determined whether the user is opening the rear tailgate. When there is at least one consistent comparison result, it is determined that at least one function among the multiple functions has obtained the opening and closing instruction of the rear tailgate.

[0079] When at least one of the plurality of functions obtains a switch instruction of the rear tailgate, the rear tailgate is controlled to perform an opening / closing operation.

[0080] In addition, in order to facilitate users to take and put items and improve user experience, in one embodiment of the present application, the height information of the legal user is obtained. According to the height information of the legal user, the corresponding relationship table is queried to determine the target height after the vehicle tailgate is opened, wherein the corresponding relationship table includes the correspondence between the user's height information and the target height of the vehicle tailgate. Then, the vehicle tailgate can be opened according to the target height, thereby ensuring that the height of the tailgate meets the user's hand reach area, and ensuring that the user can easily carry goods or manually close the door.

[0081] At the same time, after the height of the vehicle's tailgate is determined by looking up the table according to the height information of the legal user, it is determined whether there is an obstacle in the opening travel of the vehicle's tailgate. The obstacle may be a person or a wall, etc. When a person is too close to the vehicle's tailgate, the door opening is likely to cause harm to the human body; when the rear of the vehicle is too close to an object such as a wall, it is easy to collide or scratch with the obstacle during the opening process. When there is an obstacle, the target height after the vehicle's tailgate is opened is re-determined according to the obstacle, so that the target height after the door is opened is less than the height of the obstacle. For example, the distance between the vehicle's tailgate and the obstacle is controlled to be not less than a preset distance, and the opening height of the vehicle's tailgate is no longer determined according to the user's height.

[0082] Furthermore, if the opening range of the vehicle's rear tailgate still cannot reach the user's target height, the height of the vehicle's air suspension is adjusted. Specifically, when the upper limit of the height after the vehicle's rear tailgate is opened is less than the target height, the height of the air suspension is adjusted so that the upper limit of the height after the vehicle's rear tailgate is opened is greater than or equal to the target height; when the lower limit of the height after the vehicle's rear tailgate is opened is greater than the target height, the height of the air suspension is adjusted so that the lower limit of the height after the vehicle's rear tailgate is opened is less than or equal to the target height.

[0083] The beneficial effects of the present application are: when the distance between the user and the rear tailgate is less than a first preset distance, multiple command acquisition functions including at least a motion sensing function in a specific area, a surround camera function, and a voice receiving function in a specific area are activated to acquire the command information output by the user; it is determined whether at least one of the multiple functions has acquired the switch command of the rear tailgate; when at least one of the multiple functions has acquired the switch command of the rear tailgate, the rear tailgate is controlled to perform an opening / closing operation. Since the command information output by the legitimate user is identified in multiple ways, the recognition accuracy of the automatic opening of the vehicle rear tailgate is improved, thereby improving the user's interactive experience.

[0084] In one embodiment, the above step S101 may be implemented as the following steps A1-A3:

[0085] In step A1, the user's foot movement is obtained through the motion sensing function of the specific area;

[0086] In step A2, the user's posture information is obtained through the look-around function;

[0087] In step A3, the user's voice information is acquired through a voice receiving function in a specific area.

[0088] In this embodiment, the user's information is collected through various devices to determine whether the user intends to open the rear tailgate, including obtaining the user's foot movements through the motion sensing function of a specific area, obtaining the user's posture information through the surround function, and obtaining the user's voice information through the voice receiving function of a specific area.

[0089] In one embodiment, the above step S102 may be implemented as the following steps B1-B2:

[0090] In step B1, at least one of the following comparison results is obtained:

[0091] Comparison results of the user's foot movements obtained through the motion sensing function of the specific area with the preset footstep instructions for opening and closing the rear tailgate, comparison results of the user's posture information obtained through the surround view function with the preset posture instructions for opening and closing the rear tailgate, and comparison results of the user's voice information obtained through the voice receiving function of the specific area with the preset voice instructions for opening and closing the rear tailgate;

[0092] In step B2, when there is at least one matching result, it is determined that at least one function among the multiple functions obtains a switch instruction for the tailgate.

[0093] In this embodiment, the collected footsteps, posture information, and voice information of the user are compared with the corresponding pre-stored information. For example, different legitimate users can store the footsteps of opening the rear tailgate in advance as the preset footstep instructions for opening and closing the rear tailgate, such as sweeping across the preset area, or kicking in the preset area, etc.; when the footsteps of the user are collected, the collected information is compared with the preset footstep instructions for opening and closing the rear tailgate, and the comparison can be performed by image recognition and other technologies. The present application does not limit the comparison method, and then determine whether the footsteps of the current user are the preset footstep instructions for opening and closing the rear tailgate. When there is a legitimate user who has not pre-stored the footstep instructions for opening and closing the rear tailgate, the footstep trend of the footstep instructions for opening and closing the rear tailgate of other legitimate users is obtained. When the footsteps of the current legitimate user are consistent with the footstep trend, it is determined that the footsteps of the current user are the preset footstep instructions for opening and closing the rear tailgate. For the preset posture instructions for opening and closing the rear tailgate, the posture information can be stored in advance by the user; or the posture determination algorithm can be obtained through the posture information of opening the door of different users collected by big data. The collected posture information of the legal user is compared with the preset posture instruction for opening and closing the rear tailgate. When the similarity with the pre-stored posture information is greater than the preset posture similarity, or the posture determination algorithm obtains the posture information of the current posture as the posture information for opening the rear tailgate of the vehicle, the posture information of the current user is determined to be the preset posture instruction for opening and closing the rear tailgate. The preset voice instruction for opening and closing the rear tailgate can be a plurality of voice instructions predetermined by the user. By comparing the voice information of the legal user with the plurality of voice instructions, it is determined whether the user is opening the rear tailgate.

[0094] When there is at least one matching result, it is determined that at least one function among the multiple functions obtains a switch instruction for the tailgate.

[0095] In one embodiment, before executing the above step S101 to enable multiple command acquisition functions including at least a motion sensing function of a specific area, a surround camera function, and a voice receiving function of a specific area to acquire the command information input by the user, the method may also be implemented as the following steps C1-C3:

[0096] In step C1, when a user to be detected whose distance from the vehicle is less than a second preset distance is detected, facial information and / or voice information of the user to be detected is collected;

[0097] In step C2, it is determined whether the facial information and / or voice information of the user to be detected is pre-stored facial information and / or voice information;

[0098] In step C3, when the facial information and / or voice information to be detected is pre-stored facial information and / or voice information, it is determined that the user to be detected is a legitimate user with the rear tailgate opening and closing authority.

[0099] In this embodiment, in order to determine whether the person who opens the door is a legitimate user of the vehicle, when a user to be detected is detected whose distance from the vehicle is less than a second preset distance, facial information and / or voice information of the user to be detected is collected, wherein the second preset distance is greater than the first preset distance. For example, when a person is detected approaching the vehicle within 3 meters of the vehicle, facial information and / or voice information of the user to be detected is collected through the vehicle's camera or microphone.

[0100] Then, it is determined whether the facial information and / or voice information of the user to be detected is pre-stored facial information and / or voice information. For example, facial features can be extracted from the collected facial information and / or voice information of the user to be detected, and the similarity can be calculated with the features of the pre-stored facial information and / or voice information. When the similarity is greater than a preset value, it is determined to be pre-stored facial information and / or voice information. Of course, there are other methods of facial recognition and voice recognition, and this application does not limit the specific recognition method.

[0101] When the facial information and / or voice information to be detected is pre-stored facial information and / or voice information, it is determined that the user to be detected is a legitimate user with rear tailgate opening and closing authority.

[0102] The beneficial effect of this embodiment is that when a user to be detected appears at a distance from the vehicle that is less than a second preset distance, the facial information and / or voice information of the user to be detected is monitored to determine whether the user is a legitimate user of the vehicle, thereby improving the safety of the vehicle and avoiding frequent monitoring of whether the tailgate of the vehicle needs to be opened.

[0103] In one embodiment, before executing the control of the tailgate to perform the opening operation in step S103, the method may also be implemented as the following steps D1-D2:

[0104] In step D1, the height information of the legal user is obtained;

[0105] In step D2, a correspondence table is queried according to the height information of the legal user to determine the target height after the vehicle tailgate is opened, wherein the correspondence table includes the correspondence between the user's height information and the target height of the vehicle tailgate.

[0106] In this embodiment, the height information of the legal user is obtained. When an instruction of the legal user to open the rear tailgate of the vehicle is detected, the height information of the legal user is obtained. Specifically, the height information of the user can be pre-stored, or the height information of the user can be determined by image recognition based on the user image collected by the camera.

[0107] The corresponding relationship table is queried according to the height information of the legal user to determine the target height after the vehicle's tailgate is opened, wherein the corresponding relationship table includes the correspondence between the user's height information and the target height of the vehicle's tailgate. The vehicle's tailgate can then be opened according to the target height, thereby ensuring that the height of the tailgate meets the user's hand reach and area, ensuring that the user can easily carry goods or manually close the door. Specifically, the corresponding relationship table can be determined by combining ergonomics with 90% of the human body height to determine a corresponding hand reach and area, and then determine the target height for opening the vehicle's tailgate. The central domain controller calls the cloud big data to determine the target height based on the human body height, making it more convenient to carry living things.

[0108] The beneficial effects of this embodiment are: obtaining the height information of the legitimate user, and querying the corresponding relationship table based on the height information of the legitimate user to determine the target height after the tailgate of the vehicle is opened, and then controlling the appropriate height of the tailgate opening according to the height of different users, to ensure the convenience of users in taking and putting items.

[0109] In one embodiment, after performing the table lookup according to the height information of the legal user in step D2 to determine the target height after the vehicle tailgate is opened, the method may also be implemented as the following steps E1-E2:

[0110] In step E1, after determining the opening height of the vehicle's tailgate by looking up the table according to the height information of the legal user, it is determined whether there is an obstacle in the opening travel of the vehicle's tailgate;

[0111] In step E2, when there is an obstacle, the target height after the tailgate of the vehicle is opened is re-determined according to the obstacle, so that the target height after the door is opened is less than the height of the obstacle.

[0112] In this embodiment, after the height of the vehicle's tailgate opening is determined by looking up a table based on the height information of the legal user, it is determined whether there is an obstacle in the vehicle's tailgate opening travel. The obstacle may be a person or a wall, etc. When a person is too close to the vehicle's tailgate, the door opening is likely to cause harm to the human body; when the rear of the vehicle is too close to an object such as a wall, it is likely to collide or scratch with the obstacle during the opening process. Therefore, during the vehicle's tailgate opening process, it is monitored whether there is an obstacle. For example, when there are other objects within a 20 cm range from the tailgate, it is determined that there is an obstacle.

[0113] When there is an obstacle, the target height after the vehicle tailgate is opened is re-determined according to the obstacle, so that the target height after the vehicle door is opened is less than the height of the obstacle. The distance between the vehicle tailgate and the obstacle is controlled to be not less than a preset distance, such as 10 cm, and the opening height of the vehicle tailgate is no longer determined according to the height of the user.
