By establishing communication between the physical car key that supports UWB technology and the vehicle, the vehicle control function can be realized, giving users a better car experience.

By determining whether the target key moves to the second area after reaching the first area and remains in the second area for a first preset time, it is determined whether the user's motion trajectory meets the triggering conditions for tailgate opening. When the target key reaches the first area and then moves to the second area, it is determined that the user's motion trend has changed, and the motion trajectory meets the second preset condition, so the user's true intention is to open the vehicle tailgate. By determining that the user's motion trend changes and remains for the first preset time, it is determined that the user has a tendency to open the tailgate at this time, thereby preventing the tailgate from opening even when the user is passing by, and reducing the rate of false triggering of the tailgate.

[0041] In the prior art, the trigger logic for opening the tailgate using UWB technology is: setting a simple trigger logic, when it detects that the user is approaching the tailgate, the tailgate is opened, thereby completing the tailgate induction opening function; or setting a complex trigger logic, the user completes multiple steps at a time to open the tailgate operation. However, since UWB technology realizes positioning by completing information exchange through electromagnetic waves, the user cannot intuitively feel the positioning area range, resulting in the user not being able to accurately complete the operating steps according to the settings and cannot successfully open the tailgate. The above two trigger logics are prone to opening the tailgate when it is detected that the user is passing by the tailgate with a charging gun, or the operating steps are too complicated, resulting in the tailgate not being able to open when the user needs it. It can be seen that the current tailgate opening trigger logic has the problems of high false touch rate and low success rate. Based on this, the present application provides a method for opening the tailgate of a vehicle to solve the above problems.

[0042] Figure 1 A flowchart of a vehicle tailgate opening method provided in an exemplary embodiment of the present application is provided. The method can be applied to a vehicle and includes the following steps:

[0043] S11. Determine a first preset condition.

[0044] The first preset condition includes: the target key moves toward the tailgate until it reaches a first area, where the first area is the area closest to the tailgate relative to other areas, for example, the first area is an area within 1 meter from the tailgate.

[0045] In one embodiment, a method for determining the first preset condition includes: a positioning module of the vehicle obtains location parameters of the vehicle, and determines coordinate data of a first area based on the location parameters of the vehicle, for example, by using a GPS (Global Positioning System) to obtain the coordinate data of the vehicle, and determines coordinate data of a first area within 1 meter of a tailgate of the vehicle, and sends the coordinate data of the first area to a control module of the vehicle. The control module substitutes the coordinate data of the first area into a pre-stored first condition for calculation to obtain a first preset condition corresponding to the current location parameters of the vehicle, wherein the first preset condition may be that the target key (x0, y0) is located within 1 meter of the tailgate of the vehicle (x c +1,y c +1), where x c with y c The unit is meter.

[0046] The first preset condition is sent to a key module of the vehicle, and the key module receives the first preset condition and sequentially executes steps S11-S13 according to the first preset condition. The key module may be a digital key controller.

[0047] In another embodiment, the method for determining the first preset condition includes: the first preset condition is pre-stored in the vehicle's key module, the key module transmits a radio frequency signal or a pulse signal, the target key transmits a response signal after receiving the signal, and by calculating the round-trip time or signal strength of the signal, determines whether the target key is within a 2-meter range from the vehicle's tailgate; determines whether the target key meets the first preset condition based on the distance between the target key and the tailgate; and performs a logical judgment on whether the tailgate is opened based on the first preset condition. The key module may be a digital key controller.

[0048] In one embodiment, before determining the first preset condition, the method further includes:

[0049] In response to searching for a smart terminal communicating in the first communication mode within a preset range, obtaining a location parameter of the smart terminal;

[0050] According to the location parameter, it is determined whether the smart terminal meets the fourth preset condition; if so,

[0051] Determine the smart terminal as the target key; wherein the fourth preset condition includes: the smart terminal is located in the fourth area; the fourth area is within the preset range, the second area is between the third area and the tailgate, and the third area is between the fourth area and the tailgate;

[0052] Connect with the target key in a second communication method.

[0053] The first communication mode may be Bluetooth communication, and the second communication mode may be communication using UWB technology.

[0054] The key module of the vehicle can be a separate module in the vehicle, or it can be integrated into the control module of the vehicle. The key module continuously broadcasts in the first communication mode, such as continuously broadcasting Bluetooth signals, searching for smart terminals that communicate in the first communication mode within a preset range. When the smart terminal and the key module are authenticated in the first communication mode, a connection is established. For example, when the two are connected by Bluetooth, the smart terminal is located via Bluetooth to obtain the location parameters of the target key. However, the accuracy of Bluetooth positioning is relatively low. When it is determined based on the location parameters of the smart terminal that the smart terminal meets the fourth preset condition, that is, it is located in the fourth area, the smart terminal is determined as the target key. At this time, the second communication mode is turned on, such as the pulse signal used in UWB technology. The key module connects to the target key after authentication through the second communication mode, thereby accurately locating the target key. Among them, the fourth area is the area farthest from the tailgate relative to other areas. Figure 2 For example, the first zone is 21, the second zone is 22, the third zone is 23, the fourth zone is 24, and the rear of the vehicle is 25. The preset range is the area outside the fourth zone. The first zone can be within 1 meter of the vehicle's tailgate, the second zone can be within 2 meters of the rear of the vehicle, the third zone can be within 10 meters of the rear of the vehicle, and the fourth zone can be within 15 meters of the rear of the vehicle.

[0055] S12: In response to the target key meeting the first preset condition, determining a second preset condition.

[0056] The second preset condition includes: the target key moves away from the tailgate until it reaches the second zone and remains in the second zone for a first preset time. The first preset time is set based on actual conditions, for example, 3 seconds. The first zone is located between the second zone and the tailgate, for example, the first zone is within 1 meter of the tailgate, and the second zone is within 2 meters of the tailgate.

[0057] Because the prior art detects a user approaching the tailgate and opens it, thus completing the tailgate sensor opening function, this triggering logic has a high rate of false triggering of the tailgate. However, the vehicle tailgate opening method provided in the present application, after detecting that the user has moved toward the tailgate to a first area, determines a second preset condition and adds tailgate opening triggering logic to determine whether the target key carried by the user has changed its movement trend from moving toward the tailgate to moving away from the tailgate, and after reaching the second area, the key remains in the second area for a first preset time. This first preset time is used to determine whether the user has an intention to open the tailgate, rather than simply passing by the tailgate without an intention to open it.

[0058] In one embodiment, the second preset condition further includes: the target key moves away from the tailgate until it reaches the second area, and stays at the target point in the second area for a first preset time period.

[0059] Since a user carrying the target key and continuously moving in the second area may also be determined to have stayed in the second area, when the user continuously moves in the second area, for example, to conduct a safety check at the tailgate, repair a tire problem, or search for signal navigation or positioning at the tailgate, the user does not actually need to open the tailgate. Therefore, to avoid the situation where the tailgate is unnecessarily opened due to the user's continuous movement in the second area, after the user arrives at the second area, it is determined whether the user has stayed at the target point in the second area for a first preset time period. The first preset time period is used to determine whether the user has the intention to open the tailgate at this time, rather than just passing by the tailgate without the intention to open it.

[0060] In one embodiment, the method for determining the second preset condition includes: the vehicle's positioning module obtains the vehicle's position parameters, determines the coordinate data of the second area based on the vehicle's position parameters, for example, obtains the vehicle's coordinate data through a GPS (Global Positioning System), determines the coordinate data of the second area within 2 meters from the vehicle's tailgate, sends the coordinate data of the second area to the vehicle's control module, and the control module substitutes the coordinate data of the second area into a pre-stored second condition for calculation to obtain a second preset condition corresponding to the vehicle's current position parameters, wherein the second preset condition may be that the target key (x1, y1) is within 2 meters (x1, y1) of the vehicle's tailgate. d +2,y d +2), where x d with y d The unit is meter.

[0061] The second preset condition is sent to a key module of the vehicle, and the key module receives the second preset condition and sequentially executes steps S12-S13 according to the second preset condition. The key module may be a digital key controller.

[0062] In another embodiment, the second preset condition is determined by pre-storing the second preset condition in a key module of the vehicle, the key module transmitting a radio frequency signal or a pulse signal, the target key transmitting a response signal upon receiving the signal, determining whether the target key is within a 2-meter range from the vehicle's tailgate by calculating the round-trip time or signal strength of the signal, determining whether the target key meets the second preset condition based on the distance between the target key and the tailgate, and performing a logical determination to open the tailgate based on the second preset condition. The key module may be a digital key controller.

[0063] In one embodiment, the opening method further includes:

[0064] In response to the target key meeting a preset condition, the vehicle's welcome light is projected onto a preset area.

[0065] The preset conditions include at least one of the following: a first preset condition and a second preset condition. The preset areas include at least one of the following: a first area and a second area.

[0066] Projecting the vehicle's welcome light to a preset area means illuminating the ground with the welcome light in the entire preset area, so that users can move to the preset area at the rear of the vehicle according to the guidance of the welcome light. Install the welcome light at the rear of the vehicle, connect the wiring harness of the welcome light to the vehicle's CAN bus, and realize the linkage between the vehicle control function and the welcome function. Through customized lighting solutions and specific installation angles, the projection range of the welcome light coincides with the preset area. Users can distinguish different areas according to the projection range of the welcome light, and then guide users to walk to different areas according to the guidance of the welcome light, complete the trigger logic of the tailgate opening, and improve the success rate of the tailgate opening. When the rear of the vehicle is against the wall and the rear distance to open the tailgate is not enough, the welcome light will be projected onto the wall, indicating that there is a risk of collision if the tailgate is opened at this time, thereby reducing the problem of tailgate collision.

[0067] In one embodiment, in response to a target key meeting a preset condition, projecting a vehicle's welcome light onto a preset area includes:

[0068] In response to the target key reaching a third preset condition among the preset conditions, projecting the welcome light onto the first area; wherein the third preset condition includes: the target key moves toward the tailgate until reaching the third area, and the second area is located between the third area and the tailgate;

[0069] In response to the target key meeting a first preset condition, a welcome light is projected onto the second area.

[0070] like Figure 2As shown, when the user carries the target key and moves toward the tailgate until reaching the third area 23, it means that the user is about to reach the tailgate of the vehicle, and the welcome light is projected to the first area 21 to guide the user to find the vehicle, and guide the user to the first area, thereby performing the triggering logic for opening the tailgate. When the user reaches the first area, the welcome light is projected to the second area to guide the user to the second area, and flashes for a certain length of time, for example, 5 seconds, to guide the user to stay in the second area for the first preset length of time, for example, 3 seconds, to complete the triggering logic for opening the tailgate, thereby improving the success rate of opening the tailgate.

[0071] S13 : In response to the target key meeting a second preset condition, determining to open the tailgate.

[0072] When the user carries the target key and meets the second preset condition, the tailgate opening trigger logic is determined to have completed the user's intention to open the tailgate, and the vehicle then opens the tailgate. The system then determines whether the user's movement has changed, from moving toward the tailgate to moving away from it. After moving away from the tailgate and reaching the second area, the user remains in the second area for a first preset time. By determining that the user has changed their movement and remains in the second area for the first preset time after the change in movement, the system determines that the user has an intention to open the tailgate. This prevents the tailgate from being opened even when the user is passing by it, thus reducing the risk of accidental tailgate openings.

[0073] In one embodiment, after connecting with the target key in the second communication mode, the method further includes:

[0074] In response to the target key not meeting the first preset condition or the second preset condition within the second preset time period, the second communication mode is turned off and the connection with the target key is disconnected.

[0075] The second preset duration is set according to actual conditions, for example, 3 minutes.

[0076] When the target key carried by the user does not meet the first preset condition or the second preset condition within the second preset time period, it means that the user just happens to enter the vicinity of the tailgate and has no need to open the tailgate. In order to reduce power consumption, the second communication mode is turned off at this time, such as turning off the pulse signal used in UWB technology.

[0077] In one embodiment, after starting the second communication mode and connecting with the target key in the second communication mode, the method further includes:

[0078] In response to the target key not meeting the first preset condition and the second preset condition within the second preset time period, the second communication mode is closed.

[0079] The second preset duration is set according to actual conditions, for example, 3 minutes.

[0080] When the target key carried by the user does not meet the first preset condition and the second preset condition within the second preset time period, it means that the user has not completed the trigger logic for opening the tailgate and the user has no need to open the tailgate. In order to reduce power consumption, the second communication mode is turned off at this time, such as turning off the pulse signal used in UWB technology.

[0081] The following combination Figure 2 、 Figure 3 , further explanation of the method of opening the vehicle tailgate:

[0082] The vehicle's key module continuously broadcasts via a first communication method, such as a Bluetooth signal, searching for smart terminals within a preset range that communicate via the first communication method. After the smart terminal and the key module authenticate and establish a connection using the first communication method, for example, when the two are connected via Bluetooth, the smart terminal is located via Bluetooth to obtain the target key's location parameters. However, Bluetooth positioning accuracy is relatively low. When the smart terminal's location parameters determine that the smart terminal is within the fourth area or when the main vehicle door is detected to be open, the smart terminal is identified as the target key and a second communication method is initiated, such as a UWB positioning pulse signal. The key module authenticates and connects to the target key via the second communication method, thereby accurately locating the target key. The UWB master node is the vehicle's key module, and the UWB slave nodes are the UWB positioning points at the four corners of the vehicle. The target key continuously transmits its real-time location parameters to the vehicle's UWB master and slave nodes. After the UWB slave nodes return the real-time location parameters to the UWB master node, the UWB master node completes the key's precise location and outputs the location area. The key module then initiates the tailgate opening triggering logic. If it is detected that the tailgate of the vehicle is open at this time, the triggering logic for opening the tailgate is terminated.

[0083] If the tailgate of the vehicle is not opened at this time, a tailgate welcome request is sent to the vehicle's VIU (Vehicle Information Unit). The VIU forwards the tailgate welcome request to the vehicle's welcome light control module. The welcome light control module controls the welcome light to turn on and project it to the third area to guide the user to the third area. During the trigger logic judgment process of the tailgate opening, the UWB positioning is continuously turned on for a second preset time length, for example, 3 minutes. If the user does not complete the tailgate opening trigger logic within 3 minutes, the UWB positioning is turned off. If the key module determines that the target key is in the fourth area again within 3 minutes, the tailgate trigger logic is turned on again. If it is detected within 3 minutes that the user is carrying the target key and moving towards the tailgate until reaching the third area 23, it means that the user is about to reach the tailgate of the vehicle. The welcome light is projected to the first area 21 to guide the user to find the vehicle and guide the user to the first area, thereby triggering the tailgate opening. When the user reaches the first area and stands still for 3 seconds, the welcome light is projected to the second area to guide the user to the second area and flash for a certain length of time, for example, 5 seconds, to guide the user to stay in the second area for a first preset length of time, for example, 3 seconds. When the user completes the triggering logic for opening the tailgate, it is determined that the user needs to open the tailgate. At this time, the welcome light is turned off and the tailgate is opened.

[0084] It should be understood that although Figure 1-3 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. In addition, Figure 1-3 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.
