[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment one:

[0035] According to relevant technical records, traditional ways of opening a car tailgate include manual opening, physical key opening, trunk button opening, kick opening (vehicles with kick sensors) and key sensing opening.

[0036] Among them, manual opening is mainly done by the user manually unlocking the door and opening it with the force of his arm. With the development of science and technology, a method of remotely controlling the opening and closing state of the tailgate through a wireless key has gradually emerged. The user can control the opening and closing of the tailgate by operating the key, such as pressing a specific button on the key. However, this method and the method of opening the tailgate with a physical key both require the user to carry the key with them, and a series of actions such as finding the key and operating the key are required when using it, which results in a poor user experience.

[0037] For the trunk button opening and physical key opening methods, users need to find a small specific area when opening the tailgate. The former requires finding the opening button, and the latter requires finding the keyhole. These two car tailgate opening methods are difficult for users to locate in poor light and are not easy to operate.

[0038] The foot-kick-to-open method is mainly limited by the sensitivity of the foot switch, which is easy to be opened by mistake or difficult to open.

[0039] For one or more of the above technical issues, please refer to Figure 1 , Figure 1 A flow chart of an embodiment of a method for controlling a car tailgate provided by an embodiment of the present invention. The method for controlling a car tailgate can be applied to a computer device, which can be a vehicle-mounted terminal or a vehicle body controller.

[0040] The vehicle tailgate control method provided in this embodiment is applied to a target vehicle, wherein the target vehicle includes an electric tailgate.

[0041] The vehicle tailgate control method includes steps S101 to S103; wherein the specific contents of each step are as follows:

[0042] Step S101, acquiring a tactile sensing signal.

[0043] In this step, if Figure 2 As shown, a tactile sensor may be provided in a specific area of ​​the target vehicle, and the tactile sensor is used to collect elastic wave signals and convert the elastic wave signals into tactile sensing signals. The tactile sensor may be deployed in the specific area by pasting. When the tactile sensor is deployed over a large area, it may reduce the difficulty of user positioning and improve the user experience. The deployment area may be set based on comprehensive considerations of factors such as user experience and cost.

[0044] Specifically, the specific area of ​​the target vehicle may be a partial or entire area of ​​an electric tailgate of the target vehicle (e.g., the inner side of an electric tailgate cover). The specific area of ​​the target vehicle may also be the interior of the target vehicle. Therefore, the tactile sensor may be disposed on the electric tailgate of the target vehicle and / or the interior of the target vehicle.

[0045] In this way, when the user needs to open the electric tailgate, he can touch the tactile sensor arranged on the electric tailgate. Furthermore, the user can touch by bending the finger and tapping with the joint of the finger, or by tapping with other body parts such as the finger, elbow and wrist, or by using an object to tap the area where the tactile sensor is arranged.

[0046] When a user touches or taps an area where a tactile sensor is deployed, an elastic wave is generated inside or on the surface of the physical medium in the touched area. The elastic particles in the medium are disturbed and move in a specific direction, while driving adjacent particles to move in the same direction, thereby presenting a process of outward transmission of the wave. At this time, the tactile sensor can collect the elastic wave.

[0047] The tactile sensor detects and collects the elastic waves, processes and analyzes the elastic waves, obtains tactile sensing signals, and sends the signals to the vehicle controller; the vehicle controller obtains the tactile sensing signals from the tactile sensor.

[0048] In some preferred embodiments, the tactile sensor can be connected to the vehicle body controller via a CAN bus. To avoid misidentification or mistriggering of the tactile sensor, when a user carries a wireless key close to a target vehicle and enters a specific range, the vehicle body controller can be awakened by a radio frequency signal and the step of acquiring the tactile sensor signal can be executed.

[0049] Exemplarily, the preferred implementation includes: receiving a radio frequency signal; obtaining corresponding key information according to the radio frequency signal; and performing identity verification on the key information, and obtaining the tactile sensing signal when the verification is passed. When the user brings the wireless key close to the target vehicle and enters the effective range, the radio frequency receiver integrated in the vehicle body controller receives the radio frequency signal, obtains the corresponding key information and determines the legitimacy of the key. If it is identified as a legitimate key, the tactile sensing signal can be obtained at this time.

[0050] Step S102, when the tactile sensing signal meets the preset signal condition, a face image is obtained, and preset face data is queried based on the face image.

[0051] In some implementations, the preset signal condition may be set according to the strength of the user's touch, the area of ​​the touch, the mode of the touch, and / or the specific location of the touch.

[0052] For example, taking the force of the user's touch as an example, the tactile sensing signal is analyzed to obtain the force value. For example, when a tactile sensor based on elastic wave analysis is used, the elastic wave and the movement of the detection particle can be collected for analysis to obtain the force value. For another example, when a strain detection type sensor is used, the user's touch can change the geometric shape of the strain material on the contact surface, thereby causing the resistance of the material to change. The magnitude of the contact force can be measured by the resistance change, thereby obtaining the above-mentioned force value.

[0053] When the force value is greater than the preset force threshold, it is determined that the tactile sensor signal meets the preset signal condition and the face image is obtained. In this way, the tactile sensor signal generated by multiple touches is filtered through the force threshold, which can avoid the risk of false triggering caused by some external factors such as weather factors such as rain and hail, or environmental factors such as fallen leaves.

[0054] The body controller further processes and analyzes the tactile sensor signal to determine whether the preset signal conditions are met. When it is determined that the conditions are met, the vehicle host controls the image acquisition device to obtain the facial image.

[0055] like Figure 2 As shown, the image acquisition device can be arranged in any area of ​​the vehicle, and the image device can be a camera or include a camera, and the camera is aimed at the electric tailgate area of ​​the target vehicle. In other embodiments, the camera can also be aimed at the interior of the target vehicle. In this implementation, the arrangement area of ​​the camera and the tactile sensor can be considered to be matched. For example, when the tactile sensor is arranged inside the target vehicle, the camera is aimed at the interior of the target vehicle; when the tactile sensor is arranged on the electric tailgate, the camera can be aimed at the electric tailgate area of ​​the target vehicle.

[0056] Before obtaining a facial image, the vehicle host needs to be unlocked and woken up. The vehicle host continuously captures a number of images (or videos) by controlling the image acquisition device, and the image acquisition device sends them to the vehicle host via GMSL communication. Then, the vehicle host analyzes the image and extracts the facial image.

[0057] In some embodiments, the triggering time for unlocking and waking up the vehicle host may be when it is determined that a preset signal condition is met. In other embodiments, the triggering time may also be when the user brings the wireless key close to the target vehicle and enters the effective range, that is, the body controller receives the radio frequency signal and obtains the corresponding key information, authenticates the key information, and determines that the authentication is passed.

[0058] Furthermore, a preset database is queried through the extracted face image, and the preset database includes preset face data.

[0059] Step S103, when the target object face is found from the preset face data, the electric tailgate of the target vehicle is controlled to open.

[0060] In this step, the preset face data may be a plurality of preset face features, and each of the plurality of face features corresponds to a target object.

[0061] Furthermore, matching operations are performed based on the facial features and the plurality of preset facial features respectively; when the result of the matching operation indicates that the facial features match the corresponding preset facial features, it is determined that the target object face is queried from the preset facial data.

[0062] In some implementations, the matching operation may be performed by calculating face similarity or feature similarity, and when the face similarity or feature similarity is greater than a preset similarity threshold, the matching is determined to be successful.

[0063] When it is determined that the target object's face is found from the preset face data, the image acquisition device sends a "valid" signal to the body controller via the CAN bus, and the "valid" signal recognized by the above-mentioned tactile sensor is also provided to the body controller via the CAN bus. The body controller determines that the conditions for opening the electric tailgate are met and controls the opening of the electric tailgate of the target vehicle.

[0064] Furthermore, the condition for opening the electric tailgate may also consider other information, such as whether the gear is in P gear, whether the vehicle speed is less than a set threshold, etc., to further reduce the risk of false triggering. Therefore, in some preferred embodiments, the control method further includes: when the target object face is queried from the preset face data, obtaining the gear information and speed value of the target vehicle; when the gear information indicates that the target vehicle is in P gear and the speed value of the target vehicle is less than the preset speed value, controlling the electric tailgate to open.

[0065] In some preferred embodiments, the actuator for opening the electric tailgate mainly includes a tailgate lock motor and a support rod motor.

[0066] For example, controlling the opening of the electric tailgate of the target vehicle includes: sending a first drive signal to a tailgate lock motor corresponding to the electric tailgate, so that the tailgate lock motor unlocks the electric tailgate according to the first drive signal; sending a second drive signal to a strut motor corresponding to the electric tailgate, so that the strut motor controls the electric tailgate of the target vehicle to open a stroke corresponding to the second drive signal according to the second drive signal.

[0067] It can be understood that in some vehicles, the strut motor includes a left strut motor and a right strut motor, and the left strut motor and the right strut motor are respectively arranged on both sides of the electric tailgate. After the tailgate lock motor unlocks the electric tailgate according to the first drive signal, the left strut motor and the right strut motor can be driven at the same time to control the travel corresponding to the electric tailgate opening drive signal of the target vehicle. In addition, the buzzer can also be driven, and the electric tailgate status can be fed back to the display component of the target vehicle, such as the instrument panel, the central control screen, etc., so that the user can control the electric tailgate status in real time.
