[0057] The present invention provides a method and device for controlling an electric tailgate, which solves the technical problem of how to ensure the illumination range of the tailgate lighting behind the vehicle.

[0058] To better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] The fixed end of the vehicle's electric tailgate is fixed to the vehicle body. The electric tailgate can rotate around the fixed end when opened or closed. The end opposite the fixed end is the free end. In this embodiment of the invention, the lighting lamp is installed inside the free end of the electric tailgate. Figure 1 As shown, the lighting fixture includes a lampshade and a spotlight located inside the lampshade. The lampshade can be an opaque hemispherical structure with its light outlet pointing vertically downwards. The light outlet is transparent, and the spotlight can move up and down along the vertical line of the light outlet of the lampshade. Assuming that the electric tailgate is at its maximum opening and the spotlight is positioned at the top of the lampshade, it can just illuminate the area within a target distance (e.g., 1.5m) behind the vehicle, then the initial position of the spotlight is the top of the lampshade.

[0060] like Figure 2 As shown, W represents the target distance, light path f1 is the light path after the light passes the lower right edge of the lampshade when the power tailgate is at its maximum opening and the spotlight is located at the top of the lampshade, and F is the trajectory of the light when the power tailgate opens and closes. It can be understood that when the power tailgate opening decreases, if the position of the spotlight remains unchanged, the area illuminated behind the vehicle by the spotlight will essentially decrease. Figure 2 In the light path f2, the illuminated area corresponding to light path f2 is obviously smaller than W. If the height of the spotlight is reduced so that its light path becomes f3, the illuminated area of ​​the light can reach W.

[0061] The vehicle electric tailgate control method of this invention is used to control the lighting on the electric tailgate. Based on the above description, the method includes:

[0062] Step S1: After the power tailgate and spotlights are opened, obtain the opening degree of the power tailgate;

[0063] Step S2: If the opening degree of the electric tailgate is within the preset opening degree range, then determine the offset height of the spotlight according to the opening degree of the electric tailgate.

[0064] Step S3: Control the spotlight to move to the target position so that the spotlight illuminates the area within the target distance behind the vehicle. The distance between the target position and the initial position of the spotlight is the offset height.

[0065] Considering that if the opening degree of the electric tailgate is lower than Figure 2 In this context, 'a' represents the angle between the closed power tailgate and the plane containing its fixed end. Since the size of the illuminated area has little impact on the user, we only consider spotlight control when the power tailgate's opening is between 'a' and its maximum opening. That is, the preset opening range in step S2 is between 'a' and the maximum opening. The process of determining the spotlight offset height based on the power tailgate's opening is described below.

[0066] If you want to Figure 2 If the illumination range of the solid-line lighting lamp reaches W, then the light path of the spotlight should be changed from f2 to f3, where Y is the angle between the light path f3 and the vertical line where the spotlight is located. Therefore, according to... Figure 2 have D is the width of the lampshade, B is the distance between the initial position of the spotlight and the light outlet of the lampshade, h is the offset height, L is the distance between the initial position of the spotlight and the fixed end of the power tailgate, b is the opening degree of the power tailgate, and H is the distance between the fixed end of the power tailgate and the ground. Here, W is a known value. D, B, L, and H are all pre-measured and are also considered known values. After obtaining b, the equations are combined... h can be calculated. Therefore, in step S3, determining the offset height of the spotlight based on the opening degree of the electric tailgate includes:

[0067]

[0068] As can be seen from the above, the vehicle electric tailgate control method of the present invention can determine the offset height of the spotlight according to the opening degree of the electric tailgate after the electric tailgate and the spotlight are opened, and control the spotlight to move to the target position based on the offset height, so that the spotlight can illuminate the area within the target distance behind the vehicle, ensuring that the electric tailgate lighting provides the user with the illumination range behind the vehicle at night.

[0069] Vehicles typically have a camping mode. After a user selects camping mode, the vehicle can enter camping mode if certain conditions are met. In camping mode, the vehicle will play music to match the camping atmosphere. Before step S1, the vehicle electric tailgate control method of this embodiment further includes: after the user selects camping mode, obtaining the vehicle speed, gear, and slope; if the vehicle speed is zero, the gear is P, and the slope is within a preset slope range, then controlling the vehicle to enter camping mode; otherwise, preventing the vehicle from entering camping mode. It can be understood that, to ensure vehicle safety, camping mode can only be activated when the vehicle speed is zero and the gear is P. In addition, if the vehicle is parked on a slope, the vehicle's camping-related functions cannot function effectively. To make the vehicle provide camping functions more effectively, this embodiment of the invention also requires the vehicle to enter camping mode only when the slope is within a preset slope range, which can be ±5°.

[0070] In camping mode, the power tailgate is generally closed, but in open-air conditions, it needs to provide some rain protection during rain. To make the rain protection function of the power tailgate more intelligent in rainy weather, before step S1, the vehicle power tailgate control method of this embodiment may further include: when the vehicle is in camping mode, acquiring the real-time rainfall of the environment where the vehicle is located; if the real-time rainfall exceeds a rainfall threshold, reminding the user to open the power tailgate; and opening the power tailgate after receiving the opening command. Here, real-time rainfall exceeding the rainfall threshold indicates heavy rainfall. Considering that the user may not be camping outdoors and may not need to open the tailgate during rain, only reminding the user to open the tailgate is done; the tailgate opens automatically after the user issues the opening command.

[0071] When camping outdoors, the electric tailgate needs to provide some radiation protection when ultraviolet radiation is too strong. To make the radiation protection function of the electric tailgate more intelligent when ultraviolet radiation is too strong, before step S1, the vehicle electric tailgate control method of this embodiment may further include: when the vehicle is in camping mode, acquiring the light radiation intensity of the environment where the vehicle is located; if the light radiation intensity exceeds the radiation threshold, reminding the user to open the electric tailgate; and opening the electric tailgate after receiving the opening command.

[0072] When camping at night, the electric tailgate is needed to provide lighting. To make the lighting function of the electric tailgate more intelligent when camping at night, before step S1, the vehicle electric tailgate control method of this embodiment may further include: when the vehicle is in camping mode, obtaining the light intensity of the environment where the vehicle is located; if the light intensity is lower than the light intensity threshold, reminding the user to open the electric tailgate; and after receiving the opening command of the electric tailgate, turning on the electric tailgate and the spotlight.

[0073] The fixed end of the vehicle's electric tailgate is fixed to the vehicle body. The electric tailgate can rotate around the fixed end when opened or closed. The end opposite the fixed end is the free end. In this embodiment of the invention, the lighting lamp is installed inside the free end of the electric tailgate. Figure 1 As shown, the lighting fixture includes a lampshade and a spotlight located inside the lampshade. The lampshade can be an opaque hemispherical structure with its light outlet pointing vertically downwards. The light outlet is transparent, and the spotlight can move up and down along the vertical line of the light outlet of the lampshade. Assuming that the electric tailgate is at its maximum opening and the spotlight is positioned at the top of the lampshade, it can just illuminate the area within a target distance (e.g., 1.5m) behind the vehicle, then the initial position of the spotlight is the top of the lampshade.

[0074] like Figure 2As shown, W represents the target distance, light path f1 is the light path after the light passes the lower right edge of the lampshade when the power tailgate is at its maximum opening and the spotlight is located at the top of the lampshade, and F is the trajectory of the light when the power tailgate opens and closes. It can be understood that when the power tailgate opening decreases, if the position of the spotlight remains unchanged, the area illuminated behind the vehicle by the spotlight will essentially decrease. Figure 2 In the light path f2, the illuminated area corresponding to light path f2 is obviously smaller than W. If the height of the spotlight is reduced so that its light path becomes f3, the illuminated area of ​​the light can reach W.

[0075] The vehicle electric tailgate control device of this invention is used to control the lighting on the electric tailgate. Based on the above description, the device includes:

[0076] The acquisition module is used to acquire the opening degree of the electric tailgate after the electric tailgate and spotlights are opened;

[0077] The determination module is used to determine the offset height of the spotlight based on the opening degree if the opening degree is within the preset opening degree range;

[0078] The control module is used to control the spotlight to move to the target position so that the spotlight illuminates the area within the target distance behind the vehicle. The distance between the target position and the initial position of the spotlight is the offset height.

[0079] Considering that if the opening degree of the electric tailgate is lower than Figure 2 Let 'a' be the angle between the closed power tailgate and the plane containing its fixed end. The size of the illuminated area has little impact on the user; therefore, we only consider spotlight control when the power tailgate opening is between 'a' and its maximum opening. The preset opening range is between 'a' and the maximum opening. The process of determining the spotlight offset height based on the power tailgate opening is described below.

[0080] If you want to Figure 2 If the illumination range of the solid-line lighting lamp reaches W, then the light path of the spotlight should be changed from f2 to f3, where Y is the angle between the light path f3 and the vertical line where the spotlight is located. Therefore, according to... Figure 2 have D is the width of the lampshade, B is the distance between the initial position of the spotlight and the light outlet of the lampshade, h is the offset height, L is the distance between the initial position of the spotlight and the fixed end of the power tailgate, b is the opening degree of the power tailgate, and H is the distance between the fixed end of the power tailgate and the ground. Here, W is a known value. D, B, L, and H are all pre-measured and are also considered known values. After obtaining b, the equations are combined... h can be calculated. Therefore, the module determines the offset height of the spotlight based on the opening degree of the electric tailgate, including:

[0081] As can be seen from the above, the vehicle electric tailgate control device of the present invention can determine the offset height of the spotlight according to the opening degree of the electric tailgate after the electric tailgate and the spotlight are opened, and control the spotlight to move to the target position based on the offset height, so that the spotlight can illuminate the area within the target distance behind the vehicle, ensuring that the electric tailgate lighting provides the user with the illumination range behind the vehicle at night.

[0082] Vehicles typically have a camping mode. After a user selects camping mode, the vehicle can enter camping mode if certain conditions are met. In camping mode, the vehicle plays music to enhance the camping atmosphere. In the vehicle electric tailgate control device of this embodiment: the acquisition module can also be used to acquire the vehicle speed, gear, and slope after the user selects camping mode; the control module can also be used to control the vehicle to enter camping mode if the vehicle speed is zero, the gear is in P (Park), and the slope is within a preset slope range; otherwise, the vehicle is prohibited from entering camping mode. It is understood that, to ensure vehicle safety, camping mode can only be activated when the vehicle speed is zero and the gear is in P (Park). Furthermore, if the vehicle is parked on a slope, the vehicle's camping-related functions cannot function effectively. To make the vehicle provide camping functionality more effective, this embodiment of the invention also requires the vehicle to enter camping mode only when the slope is within a preset slope range, which can be ±5°.

[0083] In camping mode, the power tailgate is generally closed, but in open-air conditions, it needs to provide some rain protection during rain. To make the rain protection function of the power tailgate more intelligent in rainy weather, the vehicle power tailgate control device of this embodiment includes: an acquisition module, which can also be used to acquire the real-time rainfall of the vehicle's environment when the vehicle is in camping mode; a reminder module, which reminds the user to open the power tailgate if the real-time rainfall exceeds a rainfall threshold; and a control module, which can also be used to open the power tailgate after receiving an opening command. The real-time rainfall exceeding the rainfall threshold indicates heavy rainfall. Considering that the user may not be camping outdoors and may not need to open the tailgate during rain, the device only reminds the user to open the tailgate, and then automatically opens it after the user issues an opening command.

[0084] When camping outdoors, the electric tailgate needs to provide some radiation protection when ultraviolet radiation is too strong. To make the radiation protection function of the electric tailgate more intelligent when ultraviolet radiation is too strong, the vehicle electric tailgate control device of this embodiment includes: an acquisition module, which can also be used to acquire the light radiation intensity of the environment in which the vehicle is located when the vehicle is in camping mode; a reminder module, which is used to remind the user to open the electric tailgate if the light radiation intensity exceeds the radiation threshold; and a control module, which can also be used to open the electric tailgate after receiving the opening command of the electric tailgate.

[0085] When camping at night, the electric tailgate is needed to provide lighting. To make the lighting function of the electric tailgate more intelligent during night camping, the vehicle electric tailgate control device of this embodiment includes: an acquisition module, which can also be used to acquire the light intensity of the environment in which the vehicle is located when the vehicle is in camping mode; a reminder module, which is used to remind the user to open the electric tailgate if the light intensity is lower than the light intensity threshold; and a control module, which can also be used to turn on the electric tailgate and spotlights after receiving the opening command of the electric tailgate.
