DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0030] The following will be combined Figure 1 The implementation of the embodiment of the present application is described in detail. The embodiment of the present application provides a control method for a vehicle tailgate, which is applied to a control module of a control device for a vehicle tailgate.

[0031] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle rear door control device provided in an embodiment of the present application. Figure 1 As shown, the vehicle back door control method provided in the embodiment of the present application can be applied to Figure 1 The control module 105 in the vehicle tailgate control device 100 shown in the figure, the vehicle tailgate control device 100 also includes a vehicle unlocking detection module 101, a face detection module 102, a voice detection module 103 and a tailgate control execution module 104; the vehicle unlocking detection module 101, the face detection module 102, the voice detection module 103 and the tailgate control execution module 104 are electrically connected to the control module 105 respectively.

[0032] The vehicle unlocking detection module 101 is used to detect whether a user has unlocked the vehicle in a legal manner, such as using a key, remote control, or mobile phone APP.

[0033] The face detection module 102 is used to collect facial images of people outside the vehicle and perform recognition and judgment.

[0034] The voice detection module 103 is used to receive and process the voice instructions issued by the user.

[0035] The rear door control execution module 104 is used to drive the control action of the rear door of the vehicle through an actuator such as an electric drive device or a hydraulic device.

[0036] A method for controlling a vehicle tailgate provided in an embodiment of the present application is described in detail below. The method can be applied to a control module of the control device for the vehicle tailgate described above.

[0037] See also Figure 2 , Figure 2 This is a flow chart of a method for controlling a vehicle rear door provided in an embodiment of the present application. Figure 2 As shown, the vehicle back door control method provided in the embodiment of the present application includes the following steps:

[0038] S201, in response to a vehicle unlocking signal sent by the vehicle unlocking detection module when detecting that the vehicle is unlocked, sending a face detection activation signal to the face detection module.

[0039] In this step, when the vehicle is detected to be unlocked, the vehicle unlock detection module sends a face detection activation signal to the face detection and recognition module through the control module, so that the face detection and recognition module starts working immediately and uses the high-definition camera to collect facial images of people outside the vehicle.

[0040] S202, obtaining target face information detected by the face detection module, and determining a face detection and recognition result.

[0041] In this step, the control module uses the built-in face recognition algorithm to compare and analyze the facial features of the target face information collected by the face detection module with the pre-stored facial feature data of the car owner and family users to determine the face detection and recognition results.

[0042] S203: If the face detection and recognition result is an unregistered person, a wake-up working state activation signal is sent to the voice detection module.

[0043] In this step, if the recognition result is an unregistered person, the control module controls the voice detection module to be in a waiting state. Specifically, the waiting state is that only when an unregistered person speaks a preset specific wake-up command to activate the voice detection module, the voice detection module will recognize the vehicle back door control voice command.

[0044] S204, in response to the vehicle backdoor control signal sent by the voice detection module after detecting the correct voice wake-up command and the vehicle backdoor control voice command, forwarding the vehicle backdoor control signal to the vehicle backdoor control execution module, so that the vehicle backdoor control execution module controls the vehicle backdoor according to the vehicle backdoor control signal.

[0045] In this step, the control module responds to the vehicle backdoor control signal sent by the voice detection module after detecting the correct voice wake-up command and the vehicle backdoor control voice command, and forwards the vehicle backdoor control signal to the vehicle backdoor control execution module, so that the vehicle backdoor control execution module controls the vehicle backdoor according to the vehicle backdoor control signal.

[0046] For example: Mr. Li is in the car, and his friend helps him get something from the trunk. When the friend walks to the back door, the face detection module recognizes that he is an unregistered person, and the voice detection module is in the waiting state. The friend needs to first say the preset voice wake-up command to wake up the voice detection module, and then say the vehicle back door control voice command "open the back door". The control module confirms the vehicle back door control signal and forwards it to the vehicle back door control execution module to control the back door to open. If you don't know the specific voice wake-up command, you can't open the back door by voice control.

[0047] In a possible implementation, the method further includes:

[0048] Step a1: If the face detection and recognition result is a registered person, a wake-up-free working state activation signal is sent to the voice detection module.

[0049] In this step, if the recognition result is a registered person such as the car owner or a family user, the control module controls the voice detection module to be in the non-wake-up working state by sending a non-wake-up working state activation signal. In this state, the user does not need to say a specific voice wake-up command to wake up the voice detection module, and the voice detection module can directly detect the vehicle back door control voice command.

[0050] Step a2, in response to the vehicle backdoor control signal sent by the voice detection module after detecting the vehicle backdoor control voice command, forwarding the vehicle backdoor control signal to the vehicle backdoor control execution module, so that the vehicle backdoor control execution module controls the vehicle backdoor according to the vehicle backdoor control signal.

[0051] In this step, the voice detection module is in a monitoring state and is ready to receive the vehicle back door control voice command at any time. The control module responds to the vehicle back door control signal sent by the voice detection module after detecting the vehicle back door control voice command, and forwards the vehicle back door control signal to the vehicle back door control execution module, so that the vehicle back door control execution module controls the vehicle back door according to the vehicle back door control signal.

[0052] For example, when Mr. Li, the car owner, comes home from get off work, carrying a shopping bag, he walks to the car, and the key is approached to automatically recognize and unlock the car. After the vehicle unlocking detection module activates the relevant modules, the face detection module quickly recognizes that it is the car owner Mr. Li, and the voice detection module is in the wake-up-free state. Mr. Li directly says the vehicle back door control voice command "Open the back door", and the control module immediately confirms the vehicle back door control signal and forwards it to the vehicle back door control execution module to control the vehicle back door to open.

[0053] Further, S202 specifically includes:

[0054] Step b1, obtaining the target face information detected by the face detection module, and comparing and analyzing the target face information with the pre-stored face information of the registered user based on a preset face recognition algorithm.

[0055] Step b2: If there is a registered user whose facial information matches the target facial information, determine that the facial detection and recognition result is a registered person.

[0056] Step b3: If there is no registered user's facial information matching the target facial information, it is determined that the facial detection and recognition result is an unregistered person.

[0057] Furthermore, the method further comprises:

[0058] After sending the wake-up working state activation signal to the voice detection module, if the vehicle tailgate control voice command sent by the voice detection module is not received after a preset time, a working state shutdown signal is sent to the voice detection module.

[0059] In this step, after sending the wake-up working state activation signal to the voice detection module, if the vehicle tailgate control voice command sent by the voice detection module is not received after the preset time, it means that the face detection module may be triggered by a passerby who happened to pass by. At this time, the voice detection module does not need to continue monitoring, and sends a working state shutdown signal to the voice detection module to shut down the voice detection module and stop working.

[0060] Furthermore, the method further comprises:

[0061] After sending a wake-up working state activation signal to the voice detection module, if the voice detection module receives an erroneous voice wake-up command sent a preset number of times, a working state shutdown signal is sent to the voice detection module and a vehicle back door lock signal is sent to the vehicle back door control execution module.

[0062] In this step, after sending the wake-up working state activation signal to the voice detection module, if the voice detection module receives an erroneous voice wake-up command sent by the preset number of times, it means that someone is maliciously trying to crack the voice wake-up command. At this time, a working state shutdown signal is sent to the voice detection module to shut down the voice detection module and stop working to prevent the person from continuing to try to crack the voice wake-up command. A vehicle back door locking signal is sent to the vehicle back door control execution module to lock the vehicle back door. The back door can only be opened with a key to improve the safety protection level of the vehicle back door.

[0063] The embodiment of the present application provides a control method for a vehicle back door, which is applied to a control module of a control device for a vehicle back door; the control device also includes a vehicle unlock detection module, a face detection module, a voice detection module and a back door control execution module; the vehicle unlock detection module, the face detection module, the voice detection module and the back door control execution module are electrically connected to the control module respectively; the method includes: responding to a vehicle unlock signal sent by the vehicle unlock detection module when detecting that the vehicle is unlocked, sending a face detection activation signal to the face detection module; obtaining target face information detected by the face detection module, and determining the face detection recognition result; if the face detection recognition result is an unregistered person, sending a waiting wake-up working state activation signal to the voice detection module; responding to a vehicle back door control signal sent by the voice detection module after detecting a correct voice wake-up command and a vehicle back door control voice command, forwarding the vehicle back door control signal to the vehicle back door control execution module, so that the vehicle back door control execution module controls the vehicle back door according to the vehicle back door control signal. In this way, through the dual mechanisms of face recognition and voice wake-up commands, while ensuring convenience, the safety of vehicle back door control is effectively improved.

[0064] Based on the same application concept, the embodiment of the present application also provides a vehicle tailgate control device corresponding to the vehicle tailgate control method provided in the above embodiment.

[0073] Further, when the determining unit 1052 is used to obtain the target face information detected by the face detection module and determine the face detection and recognition result, the determining unit 1052 is specifically used to:

[0074] Acquire the target face information detected by the face detection module, and compare and analyze the target face information with the pre-stored face information of the registered user based on a preset face recognition algorithm;

[0075] If the facial information of a registered user matches the target facial information, determining that the facial detection and recognition result is a registered person;
