[0042] To realize the above idea, the present invention provides an electric door control system, please refer to Figure 1 and Figure 2 ,in, Figure 1 A structural block diagram of an electric door control system provided by one embodiment of the present invention; Figure 2 The working principle diagram of the electric door control system provided by one embodiment of the present invention. Figure 1 and Figure 2As shown, the electric door control system provided by the present invention includes a terminal device 100, a positioning module 200, a vehicle controller 300 and a vibration sensing module 400, the terminal device 100 is communicatively connected with the positioning module 200, the positioning module 200 and the vibration sensing module 400 are both installed on the vehicle body, and the positioning module 200 and the vibration sensing module 400 are both communicatively connected with the vehicle controller 300; the terminal device 100 is configured to perform connection authentication with the vehicle, and after the connection authentication is passed, send a positioning signal to the positioning module 200; the positioning module 200 is configured to obtain the positioning information of the terminal device 100 relative to the vehicle according to the positioning signal, and send it to the vehicle controller 300; the vibration sensing module 400 is configured to obtain the vibration information of the preset knocking area on the vehicle, and send it to the vehicle controller 300; the vehicle controller 300 is configured to determine whether the preset electric door opening condition is met according to the positioning information and the vibration information, and control the target electric door on the vehicle to open when it is determined that the preset electric door opening condition is met.

[0043] Therefore, the electric door control system provided by the present invention can ensure that only users carrying the authenticated terminal device 100 can open the electric door on the vehicle by first using the terminal device 100 to authenticate with the vehicle, thereby effectively preventing strangers from opening the electric door on the vehicle, thereby not only avoiding the problem of accidentally touching the door to open, but also improving the safety of the vehicle; by using the terminal device 100 after the connection authentication to send a positioning signal to the positioning module 200 installed on the vehicle body, so that the positioning module 200 can obtain the positioning information of the terminal device 100 relative to the vehicle based on the positioning signal; by using the vibration sensing module 400, the vibration information of the preset knocking area on the vehicle can be obtained; by using the vehicle controller 300, when it is determined based on the positioning information and the vibration information that the preset electric door opening condition is met, the target electric door on the vehicle is controlled to open, which can not only avoid the problems of accidentally touching and failing to unlock the vehicle without feeling, but also cancel the door handle, thereby reducing the hardware cost of the whole vehicle. In addition, the user can also customize the preset knocking area, thereby saving costs while increasing the fun of the user's ride.

[0044] Specifically, the terminal device 100 and the vehicle can be connected and authenticated through wireless communication methods such as Bluetooth, WIFI (Wireless Fidelity, wireless local area network), and traditional radio frequency communication. For example, after the terminal device 100 recognizes the Bluetooth signal broadcast by the vehicle, it can click on the Bluetooth address of the vehicle to initiate connection authentication, and the connection authentication information may include but is not limited to the Bluetooth address of the terminal device 100. For more information on how to connect and authenticate between the terminal device 100 and the vehicle, please refer to the relevant technologies known to those skilled in the art, which will not be described in detail here.

[0045] Furthermore, the positioning signal may be a Bluetooth positioning signal, a UWB positioning signal, or other positioning signals known to those skilled in the art. Correspondingly, the positioning module 200 may obtain the positioning information of the terminal device 100 relative to the vehicle based on the Bluetooth positioning principle, the UWB positioning principle, or other positioning principles.

[0046] Furthermore, the positioning module 200 and the vehicle controller 300 as well as the vibration sensing module 400 and the vehicle controller 300 may be connected via a CAN (Controller Area Network) bus.

[0047] It should be noted that, as those skilled in the art can understand, the present invention does not limit the specific setting position of the preset knocking area on the vehicle body, and the user can set the preset knocking area on the vehicle body according to his or her preferences. For example, the preset knocking area can be the area where the B-pillar of the door is located.

[0048] It should also be noted that, as those skilled in the art will appreciate, the present invention does not limit the specific installation positions of the positioning module 200 and the vibration sensing module 400 on the vehicle body. For example, the positioning module 200 and the vibration sensing module 400 can be arranged at positions such as the vehicle side door, the middle of the vehicle or the tailgate of the vehicle. It should also be noted that, as those skilled in the art will appreciate, the terminal device 100 can be a smart phone, a wearable electronic device, a smart key and other electronic devices. In addition, it should be noted that the vibration sensing module 400 can be a sentinel module that comes with the vehicle, thereby effectively saving the cost of the entire vehicle. The sentinel module includes a vibration sensor 410, a camera, etc. The sentinel module is usually used by the entire vehicle to turn on photographic monitoring for anti-theft alarm when a collision is detected.

[0049] Please continue to refer to Figure 1 ,like Figure 1As shown, in some exemplary embodiments, the terminal device 100 includes a Bluetooth module 110 and an ultra-wideband wireless communication module 120, and the positioning module 200 includes multiple ultra-wideband wireless communication sensors 210; the terminal device 100 is configured to perform connection authentication with the vehicle through the Bluetooth module 110, and send a UWB positioning signal to the positioning module 200 through the ultra-wideband wireless communication module 120; the positioning module 200 is configured to determine the distance between each of the ultra-wideband wireless communication sensors 210 and the terminal device 100 according to the UWB positioning signal, thereby obtaining the positioning information of the terminal device 100 relative to the vehicle. Since ultra-wideband wireless communication has the advantages of strong penetration, low power consumption, good anti-multipath effect, high security, low system complexity, and the ability to provide precise positioning accuracy, the terminal device 100 is configured to send a UWB positioning signal to the positioning module 200 through the ultra-wideband wireless communication module 120, which can effectively ensure that each ultra-wideband wireless communication sensor 210 (UWB sensor) in the positioning module 200 can accurately calculate the distance between it and the terminal device 100 based on the UWB positioning signal, thereby effectively ensuring the accuracy of the acquired positioning information of the terminal device 100 relative to the vehicle.

[0050] Specifically, each of the ultra-wideband wireless communication sensors 210 may determine the distance between itself and the terminal device 100 according to the strength of the received UWB positioning signal.

[0051] Please continue to refer to Figure 1 ,like Figure 1 As shown, in some exemplary embodiments, the positioning module 200 further includes a Bluetooth unit 220. Therefore, by providing the Bluetooth unit 220 in the positioning module 200, the positioning module 200 and the terminal device 100 can communicate via Bluetooth.

[0052] Please continue to refer to Figure 1 ,like Figure 1 As shown, in some exemplary embodiments, the vibration sensing module 400 includes a plurality of vibration sensors 410, and the vibration sensing module 400 is configured to obtain vibration information of the preset knocking area according to the vibration signals sensed by each of the vibration sensors 410. Thus, by setting a plurality of vibration sensors 410 to feed back the vibration signals of the preset knocking area, the accuracy of the vibration information of the preset knocking area obtained can be effectively guaranteed.

[0053] Specifically, the intensity of the vibration signal sensed by each vibration sensor 410 when the preset knocking area is knocked can be obtained through vehicle calibration, so that the vibration information of the preset knocking area can be obtained according to the intensity of the vibration signal sensed by each vibration sensor 410.

[0054] In some exemplary embodiments, the preset electric door opening condition is that the terminal device 100 is in the preset unlocking area and the preset knocking area is knocked a preset number of times. Thus, by setting the preset electric door opening condition as the terminal device 100 is in the preset unlocking area and the preset knocking area is knocked a preset number of times, it can be ensured that only when the terminal device 100 is located in the preset unlocking area, the execution of the knocking action is effective, thereby effectively avoiding the problem of accidentally opening the door and effectively avoiding strangers opening the door, thereby effectively improving safety.

[0055] It should be noted that, as can be understood by those skilled in the art, the preset number of times may be defined by the user, and the present invention does not limit the specific value of the preset number of times.

[0056] In some exemplary embodiments, the vehicle controller 300 is configured to: correct the positioning information, and determine the position coordinates of the terminal device 100 relative to the vehicle according to the corrected positioning information, and determine whether the terminal device 100 is within the preset unlocking area according to the position coordinates. Thus, by first correcting the positioning information, and then determining the position coordinates of the terminal device 100 relative to the vehicle according to the corrected positioning information, it is possible to accurately determine whether the terminal device 100 is within the preset unlocking area according to the position coordinates.

[0057] Please refer to Figure 3 , which is a schematic diagram of unlocking area division provided by an embodiment of the present invention. Figure 3 As shown, the preset unlocking area can be set according to the area where the target electric door is located. Furthermore, the range of the preset unlocking area can be obtained by vehicle calibration, and the user can set the relevant parameters of the preset unlocking area by himself.

[0058] In some exemplary embodiments, the vehicle controller 300 is configured to determine the number of times the preset knocking area is knocked according to the vibration information, and after determining that the terminal device 100 is in the preset unlocking area, determine whether the number of times the preset knocking area is knocked is equal to the preset number, and if it is determined that the number of times the preset knocking area is knocked is equal to the preset number, then control the target electric door on the vehicle to open. Thus, by first determining whether the terminal device 100 is in the preset unlocking area, then determining whether the number of times the preset knocking area is knocked is equal to the preset number, and then controlling the target electric door on the vehicle to open after determining that the number of times the preset knocking area is knocked is equal to the preset number, not only can the problem of opening the door by mistake be effectively avoided, but also strangers can be effectively prevented from opening the door, thereby effectively improving safety.

[0059] Based on the same inventive concept, the present invention also provides an electric door control method, please refer to Figure 4 , which is a flow chart of an electric door control method provided by one embodiment of the present invention. Figure 4 As shown, the electric door control method provided by the present invention comprises the following steps:

[0061] Step S200: judging whether a preset electric door opening condition is met according to the positioning information and the vibration information.

[0062] If it is determined that the preset electric door opening condition is met, step S300 is executed to control the target electric door on the vehicle to open.

[0063] Thus, by first using the terminal device 100 to authenticate with the vehicle, it can be ensured that only users carrying the authenticated terminal device 100 can open the electric door on the vehicle, thereby effectively preventing strangers from opening the electric door on the vehicle, thereby not only avoiding the problem of accidentally touching the door to open, but also improving the safety of the vehicle; by using the terminal device 100 after the connection authentication to send a positioning signal to the positioning module 200 installed on the vehicle body, so that the positioning module 200 can obtain the positioning information of the terminal device 100 relative to the vehicle based on the positioning signal; by using the vibration sensing module 400, the vibration information of the preset knocking area on the vehicle can be obtained; by using the vehicle controller 300, when it is determined based on the positioning information and the vibration information that the preset electric door opening condition is met, the target electric door on the vehicle is controlled to open, which can not only avoid the problems of accidentally touching and failing to unlock the vehicle without feeling, but also cancel the door handle, thereby reducing the hardware cost of the whole vehicle. In addition, the user can also customize the preset knocking area, thereby saving costs while increasing the fun of the user's ride.
