[0017] The preferred embodiments of the present utility model are given below in conjunction with the accompanying drawings and described in detail.

[0018] like Figure 1As shown, the embodiment of the utility model provides a vehicle welcoming system, including a plurality of anchor points 10, a controller 20 and at least one welcoming light 30. One of the anchor points 10 is used as a main anchor point, the main anchor point is connected to the other anchor points in communication, the controller 20 is connected to the main anchor point in communication, and the welcoming light 30 is connected to the controller 20 in communication. The anchor point 10 is used to communicate with a portable communicative device and to measure the distance between the portable communicative device and the anchor point 10. Each anchor point 10 is fixed at a different position on the vehicle. The controller 20 can obtain the distance between each anchor point 10 and the portable communicative device through the distance between each anchor point 10 and the portable communicative device measured, and control the welcoming light 30 to turn on or off according to the distance between each anchor point 10 and the portable communicative device, so as to achieve a welcoming effect when the portable communicative device approaches the vehicle.

[0019] The portable communication device may be a vehicle key, a mobile phone, a wristband, a tablet computer or any other suitable device.

[0020] In some embodiments, the anchor point 10 can be a single anchor point, such as a UWB (ultra-wideband) anchor point or a Star Flash anchor point, or a hybrid anchor point, that is, including both a UWB anchor point and a Star Flash anchor point; wherein, a UWB anchor point refers to a device for ranging and positioning based on UWB technology, and a Star Flash anchor point refers to a device for ranging and positioning using the Star Flash technology. The Near Link technology is a short-range wireless connection technology with the advantages of high transmission accuracy, high efficiency, and wide radiation range. Therefore, the positioning range of the Star Flash anchor point is also larger. The principle of ranging and positioning by the UWB anchor point and the Star Flash anchor point is the prior art in the art and will not be repeated here. The portable communicative device is provided with a UWB tag and / or a Starflash tag (i.e., the portable communicative device is a tag node), which will send UWB signals and / or Starflash signals to the outside. The UWB anchor point can determine the distance between the portable communicative device and the UWB anchor point based on the UWB signal sent by the portable communicative device, and the Starflash anchor point can determine the distance between the portable communicative device and the Starflash anchor point based on the Starflash signal sent by the portable communicative device; for the hybrid anchor point, it can measure two distance values, one is obtained by the UWB anchor point based on the UWB signal (hereinafter referred to as the UWB distance), and the other is obtained by the Starflash anchor point based on the Starflash signal (hereinafter referred to as the Starflash distance).

[0021] like Figure 2As shown, in some embodiments, each anchor point 10 may include a first anchor point 110, two second anchor points 120 and four third anchor points 130, the first anchor point 110 and the two second anchor points 120 are arranged inside the vehicle 200 (i.e., inside the cabin), the four third anchor points 130 are arranged outside the vehicle 200 (i.e., outside the cabin), the first anchor point 110 is the main anchor point, and is communicated with the two second anchor points 120 and the four third anchor points 130 respectively, wherein the first anchor point 110 is a hybrid anchor point, the second anchor point 120 and the third anchor point 130 are both single anchor points, the second anchor point 120 is a UWB anchor point, and the third anchor point 130 is a star flash anchor point.

[0022] The four third anchor points 130 can be arranged at any suitable positions as needed. For example, the four third anchor points 130 can be fixed at the four corners of the vehicle respectively to cover the entire range of the vehicle periphery as much as possible. For example, the four third anchor points 130 can be fixed on the front and rear bumpers, fenders, reflectors or any other suitable parts.

[0023] The number of the third anchor points 130 is not limited to four, and can also be three, five or any other suitable number. The more anchor points there are, the larger the positioning range, the more accurate the positioning, and the higher the cost accordingly. When setting the number of the third anchor points 130, factors such as positioning range, positioning accuracy and cost can be comprehensively considered.

[0024] The arrangement position of the third anchor point 130 can also be set as needed. For example, when the number of the third anchor points 130 is three, one can be arranged in front of the vehicle, one can be arranged at the rear of the vehicle, and one can be arranged on the top of the vehicle; when the number of the third anchor points 130 exceeds four, in addition to being arranged at each of the four corners of the vehicle, one can also be arranged on the left side and / or right side and / or top.

[0025] In some embodiments, the first anchor point 110 and the two second anchor points 120 in the cabin may be distributed in a triangle in the same horizontal plane (i.e., a plane parallel to the XOY plane of the vehicle coordinate system). For example, the first anchor point 110 and the two second anchor points 120 may be located in the top area of ​​the vehicle (i.e., an area above the seat). The specific fixed positions of the first anchor point 110 and the two second anchor points 120 may be the front and rear reading lights, the A-pillar, B-pillar, C-pillar of the vehicle, or any other suitable position. For example, the first anchor point 110 may be fixed at the front reading light, one of the two second anchor points 120 may be fixed at the rear reading light, and the other of the two second anchor points 120 may be fixed on the C-pillar of the vehicle; or the first anchor point 110 may be fixed on the A-pillar on one side of the vehicle, one of the two second anchor points 120 may be fixed on the A-pillar on the other side of the vehicle, and the other of the two second anchor points 120 may be fixed on the C-pillar on the same side as the first anchor point 110, and so on.

[0026] In some embodiments, the first anchor point 110 and the two second anchor points 120 in the cabin may also be distributed in a triangle in the same vertical plane (i.e., a plane parallel to the XOZ plane of the vehicle coordinate system), for example, the first anchor point 110 and one of the two second anchor points 120 may be located at the top area of ​​the vehicle, and the other of the two second anchor points 120 may be located directly below the line between the first anchor point 110 and the second anchor point 120 at the top. The first anchor point 110 and the two second anchor points 120 may be fixed at any suitable position in the cabin, for example, the first anchor point 110 may be fixed at the front reading light, one of the two second anchor points 120 may be fixed at the rear reading light, and the other of the two second anchor points 120 may be fixed in the middle of the rear foot sole; or the first anchor point 110 may be fixed on the A-pillar on one side, and the two second anchor points 120 may be fixed on the B-pillar and C-pillar on the same side as the first anchor point 110, etc.

[0027] In some embodiments, the first anchor point 110 and the two second anchor points 120 may also be distributed in a triangle in the same inclined plane (i.e., a plane that forms a non-90° angle with the XOZ plane of the vehicle coordinate system), for example, one of the first anchor point 110 and the two second anchor points 120 may be set at the top area of ​​the vehicle, and the other of the two second anchor points 120 may be set below the first anchor point 110 and the second anchor point 120 in the top area. The first anchor point 110 and the two second anchor points 120 may be fixed at any suitable position in the cabin, for example, the first anchor point 110 may be fixed at the front reading light, one of the two second anchor points 120 may be fixed at the rear reading light, and the other of the two second anchor points 120 may be fixed at the welcome pedal of the rear row; or the first anchor point 110 may be fixed on the A-pillar on one side, one of the two second anchor points 120 may be fixed on the C-pillar on the same side as the first anchor point 110, and the other of the two second anchor points 120 may be fixed at the welcome pedal of the rear row on the opposite side to the first anchor point 110.

[0028] like Figure 3 As shown, in some embodiments, each anchor point may also include four first anchor points 110 , all of which are hybrid anchor points and are all located in the cabin of the vehicle, one of the first anchor points 110 is a main anchor point, and the main anchor point is communicatively connected with the other three first anchor points 110 .

[0029] In some embodiments, four first anchor points 110 may be arranged at the front, rear, left, and right sides of the vehicle cabin to cover a wider range.

[0030] In some embodiments, the four first anchor points 110 are arranged in a quadrilateral in the same horizontal plane, for example, the four first anchor points 110 can be fixed to the top area of ​​the cabin of the vehicle 200. The four first anchor points 110 can be fixed to any suitable position in the cabin, for example, the first of the four first anchor points 110 can be fixed to the front reading light, the second of the four first anchor points 110 can be fixed to the rear reading light, and the third and fourth of the four first anchor points 110 can be fixed to the C-pillars on both sides, respectively.

[0031] In some embodiments, the four first anchor points 110 may also form a three-dimensional structure, that is, the four first anchor points 110 are not arranged in the same plane, for example, two of the first anchor points 110 may be respectively arranged in the top area of ​​the cabin, and the other two first anchor points 110 may be respectively located in the bottom area of ​​the cabin (i.e., the area below the seats). The four first anchor points 110 may be fixed at any suitable position in the cabin, for example, two of the first anchor points 110 may be respectively fixed at the front and rear reading lights, and the other two may be respectively fixed at the welcome pedals on both sides of the rear row of the vehicle.

[0032] In some embodiments, the controller 20 may be configured to change the switch state and / or light color and / or light brightness of the welcome light 30 according to the distance between the portable communicative device and each anchor point 10, so as to achieve a dynamic welcome effect. For example, multiple preset distances (such as a first preset distance, a second preset distance, and a third preset distance) may be pre-set, and the first preset distance, the second preset distance, and the third preset distance decrease in sequence. When the distance between the portable communicative device and each anchor point 10 is greater than the first preset distance, the controller 20 may turn off the welcome light 30; when there is a distance between the portable communicative device and the anchor point 10 that is less than the first preset distance and greater than the second preset distance, the controller 20 may control the welcome light 30 to emit a light of a first color and a first intensity; when there is a distance between the portable communicative device and the anchor point 10 that is less than the second preset distance and greater than the third preset distance, the controller 20 may control the welcome light 30 to emit a light of a second color and a second intensity; when there is a distance between the portable communicative device and the anchor point that is less than the third preset distance, the controller 20 may control the welcome light 30 to emit a light of a third color and a third intensity.

[0033] In some embodiments, there may be multiple welcome lights 30, which are installed at different positions on the vehicle, and the controller 20 may control the switches of the multiple welcome lights 30 according to the distance between the portable communicative device and each anchor point 10. For example, each anchor point 10 corresponds to one or more welcome lights 30, and when the distance between a certain anchor point 10 and the portable communicative device is less than a preset distance, the controller 20 may control the welcome light 30 corresponding to the anchor point 10 to turn on; or, when the distance between a certain anchor point 10 and the portable communicative device is less than a preset distance, the controller 20 may control all the welcome lights 30 to turn on to provide sufficient lighting; or the controller 20 may also adopt any other suitable light control method.

[0034] The shape of the welcome lamp 30 can be set as needed to emit light in any suitable shape, such as a strip, a cross, an S shape, a grid shape, etc., so as to achieve different lighting effects.

[0035] In some embodiments, the vehicle may include multiple different portable communicative devices, each portable communicative device corresponds to a different welcome light control method. When the portable communicative device is close to the vehicle, the portable communicative device will send its own identity information to each anchor point 10, and the identity information will be transmitted to the controller 20 by the main anchor point. The controller 20 can identify the identity of the portable communicative device through the identity information, thereby controlling the welcome light 30 accordingly to achieve a corresponding welcome effect.

[0036] In some embodiments, the vehicle welcome system may further include a steering drive device, the controller 20 is connected to the steering drive device, the steering drive device is connected to the welcome light 30, the steering drive device is used to drive the welcome light 30 to turn, and the controller 20 is used to send a steering instruction to the steering drive device when necessary to control the steering of the welcome light 30 through the steering drive device.
