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

[0018] like Figure 1 As shown, an embodiment of the present invention provides a vehicle key cabin positioning system, comprising at least three anchor points 10 and a control device 20, wherein one of the anchor points 10 is formed as a main anchor point, the main anchor point is communicatively connected to the remaining anchor points, and the control device 20 is communicatively connected to the main anchor point. The anchor point 10 is used to communicate with the vehicle key and measure the distance between the vehicle key and the anchor point 10. Each anchor point 10 is fixed at a different position in the cabin of the vehicle. The main anchor point can obtain the distance between the remaining anchor points 10 and the vehicle key through the distance between each anchor point 10 and the vehicle key, and determine the position of the vehicle key in the cabin based on the distance between the remaining anchor points 10 and itself and the vehicle key, and send it to the control device 20. The control device 20 displays the position of the vehicle key in the cabin for the occupants to view, so that the occupants can find the vehicle key quickly and accurately.

[0019] In some embodiments, the anchor point 10 can be a single anchor point, such as a UWB (ultra-wideband) anchor point or a Starlight anchor point, or a hybrid anchor point, that is, including both a UWB anchor point and a Starlight anchor point; wherein, a UWB anchor point refers to a device for ranging and positioning based on UWB technology, and a Starlight anchor point refers to a device for ranging and positioning using Starlight technology. Starlight (Near Link) technology is a short-range wireless connection technology with the advantages of high transmission accuracy, high efficiency, and a wide radiation range. Therefore, the positioning range of the Starlight anchor point is also larger. The principles of ranging and positioning by UWB anchor points and Starlight anchor points are prior art in the field and will not be elaborated here. The vehicle key is equipped with a UWB tag and / or a Star Flash tag (that is, the vehicle key is a tag node), which will send UWB signals and / or Star Flash signals to the outside. The UWB anchor point can determine the distance between the vehicle key and the UWB anchor point based on the UWB signal sent by the vehicle key, and the Star Flash anchor point can determine the distance between the vehicle key and the Star Flash anchor point based on the Star Flash signal sent by the vehicle key; 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 Star Flash anchor point based on the Star Flash signal (hereinafter referred to as the Star Flash distance).

[0020] like Figure 2 As shown, in some embodiments, each anchor point 10 may include a first anchor point 110 and two second anchor points 120. The first anchor point 110 and the two second anchor points 120 are arranged inside the vehicle 200 (i.e., in the cabin). The first anchor point 110 is a main anchor point and is communicatively connected to the two second anchor points 120 respectively. Among them, the first anchor point 110 is a hybrid anchor point, and the second anchor point 120 is a UWB anchor point, that is, a single anchor point.

[0021] In some embodiments, the first anchor point 110 and the two second anchor points 120 in the cabin can be distributed in a triangular shape within 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 can be located in the top area of ​​the vehicle (i.e., an area above the seat). The specific fixed locations of the first anchor point 110 and the two second anchor points 120 can be the front and rear reading lights, the vehicle's A-pillar, B-pillar, C-pillar, or any other suitable location. For example, the first anchor point 110 can be fixed to the front reading light, one of the two second anchor points 120 can be fixed to the rear reading light, and the other of the two second anchor points 120 can be fixed to the vehicle's C-pillar. Alternatively, the first anchor point 110 can be fixed to the A-pillar on one side of the vehicle, one of the two second anchor points 120 can be fixed to the A-pillar on the other side of the vehicle, and the other of the two second anchor points 120 can be fixed to the C-pillar on the same side as the first anchor point 110, and so on.

[0022] In some embodiments, the first anchor point 110 and the two second anchor points 120 in the cabin may also be distributed in a triangular pattern within 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 of the vehicle, while the other of the two second anchor points 120 may be located directly below the line connecting 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 location within the cabin. For example, the first anchor point 110 may be fixed to the front reading light, one of the two second anchor points 120 may be fixed to the rear reading light, and the other of the two second anchor points 120 may be fixed to the center of the rear footwell. Alternatively, the first anchor point 110 may be fixed to the A-pillar on one side, while the two second anchor points 120 may be fixed to the B-pillar and C-pillar on the same side as the first anchor point 110.

[0023] In some embodiments, the first anchor point 110 and the two second anchor points 120 may be distributed in a triangular pattern within 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 located in the roof area of ​​the vehicle, while the other of the two second anchor points 120 may be located below the first anchor point 110 and the second anchor point 120 in the roof area. The first anchor point 110 and the two second anchor points 120 may be fixed to any suitable location within the cabin. For example, the first anchor point 110 may be fixed to the front reading light, one of the two second anchor points 120 may be fixed to the rear reading light, and the other of the two second anchor points 120 may be fixed to the rear passenger door step. Alternatively, the first anchor point 110 may be fixed to an A-pillar, one of the two second anchor points 120 may be fixed to 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 to the rear passenger door step on the opposite side from the first anchor point 110.

[0024] 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.

[0025] 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.

[0026] 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 location 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.

[0027] 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 located in the top area of ​​the cabin, and the other two may be located in the bottom area of ​​the cabin (i.e., below the seats). The four first anchor points 110 may be fixed to any suitable location in the cabin. For example, two of the first anchor points 110 may be fixed to the front and rear reading lights, and the other two may be fixed to the passenger door step on both sides of the rear seat.

[0028] In some embodiments, the control device 20 has a display for displaying the position of the vehicle key in the cabin.

[0029] In some embodiments, the control device 20 may also have an interactive device for enabling the occupant to interact with the control device 20. When the occupant forgets the location of the vehicle key, the occupant may use the interactive device to send a key-finding instruction to the control device 20. The control device 20 then sends the key-finding instruction to the master anchor point. The master anchor point then determines the location of the vehicle key in the cabin based on the distance between each anchor point 10 and the vehicle key, and sends the information to the control device 20, which then displays the location of the vehicle key in the cabin.

[0030] In some embodiments, the location of the vehicle key in the cabin can be displayed in the form of an image, that is, the control device 20 can display a cabin structure diagram, and then mark the location of the vehicle key in the cabin structure diagram, thereby making it easier for passengers to find it.

[0031] In some embodiments, the location of the vehicle key in the cabin can also be indicated by sound, light, or any other suitable means. For example, the cabin can be equipped with sound equipment (e.g., speakers), light equipment (e.g., ambient lighting, indicator lights), etc., and the control device 20 can be connected to the sound equipment and light equipment to send sound reminder instructions and light reminder instructions to the sound equipment and light equipment when necessary, so as to remind the vehicle key of its location through sound or light.

[0032] In some embodiments, the control device 20 may be an electronic control unit (ECU) of a vehicle, a smart device (such as a mobile phone, a tablet computer, etc.), or any other suitable device.

[0033] In some embodiments, the main anchor point and the remaining anchor points 10 may be connected via wireless communication, and the main anchor point and the control device 20 may be connected via wireless or wired communication.

[0034] In some embodiments, there may be multiple vehicle keys, each of which has identity information and will send the identity information to each anchor point 10. The main anchor point can determine the identity of the vehicle key based on the identity information. When displaying the position of the vehicle key in the cabin, the control device 20 will simultaneously display the identity information of the vehicle key so that the occupant can determine the identity of the vehicle key through its identity information.

[0035] The vehicle key cabin positioning system of the embodiment of the utility model can determine the position of the vehicle key in the cabin by the distance between each anchor point 10 and the vehicle key, with high efficiency and accurate positioning; the position of the vehicle key in the cabin can be displayed by the control device 20, making it easy for passengers to find it.
