[0028] The preferred embodiments of the present utility model are given below in conjunction with the accompanying drawings and described in detail.

[0029] In the present invention, the space that the passengers can move or touch after entering the vehicle is the interior of the vehicle, and the space between the space that the passengers can move / touch and the outer shell of the vehicle is the exterior of the vehicle.

[0030] Embodiment 1

[0031] like Figure 1 As shown, the first embodiment of the utility model provides a positioning device for a portable communicative device inside and outside a cabin, including a main anchor point 110 and at least three slave anchor points. The main anchor point 110 is arranged in the cabin of the vehicle 200. The main anchor point 110 is a hybrid anchor point composed of an ultra-wideband anchor point and a star flash anchor point. Part of each slave anchor point is an ultra-wideband (UWB) anchor point, and the other part is a star flash anchor point. The UWB anchor point is arranged in the cabin, and the star flash anchor point is arranged in the cabin; wherein, the UWB anchor point refers to a device for ranging and positioning based on the UWB technology, and the star flash anchor point refers to a device for ranging and positioning based on the star flash technology. The star flash (NearLink) technology is a short-range wireless connection technology, which has the advantages of high transmission accuracy, high efficiency, and a 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 field and will not be repeated here.

[0032] The master anchor point 110 may be connected to each slave anchor point for communication, so as to receive the distance between each slave anchor point and the portable communicative device measured by each slave anchor point.

[0033] Specifically, the at least three slave anchor points include two UWB anchor points 120 and at least three star flash anchor points 130 (for example, four). The two UWB anchor points 120 are arranged inside the cabin, and the four star flash anchor points 130 are arranged outside the cabin of the vehicle 200 .

[0034] The portable communicative device is provided with a UWB tag and a Starflash tag (that is, the portable communicative device is a tag node), which will simultaneously send out UWB signals and Starflash signals. The UWB anchor point can determine the distance between the portable communicative device and the UWB anchor point according to 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 according to the Starflash signal sent by the portable communicative device. Therefore, the main anchor point 110 can obtain two distance values, one is obtained by the UWB anchor point based on the UWB signal, and the other is obtained by the Starflash anchor point based on the Starflash signal. The UWB anchor point 120 can obtain a distance value based on the UWB signal, and the Starflash anchor point 130 can obtain a distance value based on the Starflash signal. The distances measured by the two UWB anchor points 120 and the four star flash anchor points 130 will be sent to the main anchor point 110. The main anchor point 110 can determine the position of the portable communicative device based on the distance between each star flash anchor point 130 and the portable communicative device, the distance between each UWB anchor point 120 and the portable communicative device, and the distance between the main anchor point 110 and the portable communicative device, thereby realizing the positioning of the portable communicative device.

[0035] The portable communication device may be a vehicle key, a mobile phone, a bracelet, a tablet computer or any other suitable device, which can store, receive or transmit information with identity characteristics, and its identity can be determined through the identity information.

[0036] In some embodiments, the main anchor point 110 may be connected to the electronic control unit (ECU) of the vehicle in communication, and the main anchor point 110 may issue some control instructions to the ECU according to the position of the portable communicative device, so that the ECU can achieve some desired control effects. For example, when the portable communicative device is outside the cabin of the vehicle and is at a preset distance from the vehicle, the main anchor point 110 may send a first light instruction to the ECU, and the ECU controls the lights on the outside of the vehicle to light up; or, when the portable communicative device enters the cabin of the vehicle, the main anchor point 110 sends a second light instruction to the ECU, and the ECU controls the lights on the seat where the portable communicative device is located to light up.

[0037] The four star flash anchor points 130 can be arranged at any suitable positions as needed. For example, the four star flash 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 star flash anchor points 130 can be fixed on the front and rear bumpers, fenders, reflectors or any other suitable parts.

[0038] The number of star flash anchor points 130 is not limited to four, but 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 star flash anchor points 130, factors such as positioning range, positioning accuracy and cost can be comprehensively considered.

[0039] The layout position of the star flash anchor point 130 can also be set as needed. For example, when the number of the star flash anchor points 130 is three, one can be arranged in front of the vehicle, one can be arranged behind the vehicle, and one can be arranged on the top of the vehicle; when the number of the star flash 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.

[0040] like Figure 2A and Figure 2B As shown, in some embodiments, the main anchor point 110 and the two UWB anchor points 120 are 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 main anchor point 110 and the two UWB anchor points 120 can be set in the top area of ​​the vehicle (i.e., an area above the seat). The specific fixed positions of the main anchor point 110 and the two UWB anchor points 120 can 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 main anchor point 110 can be fixed at the front reading light, one of the two UWB anchor points 120 can be fixed at the rear reading light, and the other of the two UWB anchor points 120 can be fixed on the C-pillar of the vehicle; or the main anchor point 110 can be fixed on the A-pillar on one side of the vehicle, one of the two UWB anchor points 120 can be fixed on the A-pillar on the other side of the vehicle, and the other of the two UWB anchor points 120 can be fixed on the C-pillar on the same side as the main anchor point 110, and so on.

[0041] like Figure 3A and Figure 3B As shown, in some embodiments, the main anchor point 110 and the two UWB anchor points 120 are 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 main anchor point 110 and one of the two UWB anchor points 120 can be set in the top area of ​​the vehicle, and the other of the two UWB anchor points 120 can be located directly below the line between the main anchor point 110 and the top UWB anchor point 120. The main anchor point 110 and the two UWB anchor points 120 can be fixed at any suitable position in the cabin, for example, the main anchor point 110 can be fixed at the front reading light, one of the two UWB anchor points 120 can be fixed at the rear reading light, and the other of the two UWB anchor points 120 can be fixed in the middle of the rear foot sole; or the main anchor point 110 is fixed on the A-pillar on one side, and the two UWB anchor points 120 are respectively fixed on the B-pillar and the C-pillar on the same side as the main anchor point 110, and so on.

[0042] like Figure 4A and Figure 4BAs shown, in some embodiments, the main anchor point 110 and the two UWB anchor points 120 may be distributed in a triangular shape 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, the main anchor point 110 and one of the two UWB anchor points 120 may be located in the top area of ​​the vehicle, and the other of the two UWB anchor points 120 may be located below the main anchor point 110 and the UWB anchor point 120 in the top area. The main anchor point 110 and the two UWB anchor points 120 can be fixed at any suitable position in the cabin. For example, the main anchor point 110 can be fixed at the front reading light, one of the two UWB anchor points 120 can be fixed at the rear reading light, and the other of the two UWB anchor points 120 can be fixed at the welcome pedal in the rear row; or the main anchor point 110 is fixed to the A-pillar on one side, one of the two UWB anchor points 120 can be fixed to the C-pillar on the same side as the main anchor point 110, and the other of the two UWB anchor points 120 can be fixed to the welcome pedal in the rear row on the opposite side of the main anchor point 110.

[0043] like Figure 5 As shown, when four star flash anchor points 130 are respectively fixed at the four corners of the vehicle, they can cover an elliptical monitoring range (also called a positioning range) around the vehicle. When the portable communicative device enters the monitoring range, the positioning device can detect the position of the portable communicative device.

[0044] The device for positioning a portable communicative device inside and outside a cabin of the first embodiment of the utility model can position a portable communicative device through at least three star flash anchor points outside the vehicle, so as to cover a larger positioning range and have high positioning efficiency.

[0045] Embodiment 2

[0046] like Fig. 6A and Figure 6B As shown, the second embodiment of the present invention provides a portable communication device positioning device inside and outside the cabin, which is different from the first embodiment only in that the included slave anchor points are different. Specifically, the positioning device of the second embodiment includes a main anchor point 110 and at least three slave anchor points 140, the main anchor point 110 and each slave anchor point 140 are arranged in the cabin of the vehicle 200, and the main anchor point 110 and each slave anchor point 140 are hybrid anchor points composed of an ultra-wideband anchor point and a star flash anchor point.

[0047] In some embodiments, the main anchor point 110 and the three secondary anchor points 140 may be arranged at the front, rear, left, and right sides of the cabin of the vehicle to cover a wider range.

[0048] In some embodiments, the main anchor point 110 and the three slave anchor points 140 are arranged in a quadrilateral in the same horizontal plane, for example, the main anchor point 110 and the three slave anchor points 140 can be fixed to the top area of ​​the cabin of the vehicle 200. The main anchor point 110 and the three slave anchor points 140 can be fixed to any suitable position in the cabin, for example, the main anchor point 110 can be fixed to the front reading light, the first of the three slave anchor points 140 can be fixed to the rear reading light, and the second and third of the three slave anchor points 140 can be fixed to the C-pillars on both sides respectively.

[0049] like Fig. 7A and Figure 7B As shown, the main anchor point 110 and the three slave anchor points 140 can form a three-dimensional structure, that is, the main anchor point 110 and the three slave anchor points 140 are not arranged in the same plane, for example, the main anchor point 110 and one of the slave anchor points 140 can be respectively arranged in the top area of ​​the cabin, and the other two slave anchor points 140 can be respectively located in the bottom area of ​​the cabin (i.e., the area below the seats). The main anchor point 110 and the three slave anchor points 140 can be fixed at any suitable position in the cabin, for example, the main anchor point 110 and one of the slave anchor points 140 can be respectively fixed at the front and rear reading lights, and the other two slave anchor points can be respectively fixed at the welcome pedals on both sides of the rear row of the vehicle.

[0050] like Figure 8 As shown, when the main anchor point 110 and the three slave anchor points 140 are respectively arranged on the front, back, left and right sides of the cabin, the portable communication equipment positioning device inside and outside the cabin can cover a quasi-elliptical monitoring range. Although the range is smaller than that of the first embodiment in the longitudinal direction and part of the front of the vehicle is not covered, the lateral coverage range is larger. Compared with the first embodiment, this embodiment only needs to use four anchor points, and the number of anchor points is greatly reduced, so the cost can also be reduced.

[0051] It is understandable that, although the positioning device is described above by taking three hybrid anchor points as slave anchor points 140 as an example, the positioning device for portable communicative devices inside and outside the cabin of the second embodiment can also be configured to include other numbers of hybrid anchor points as slave anchor points as needed. The layout of the main anchor point 110 and each slave anchor point 140 can also be configured as needed, for example, the main anchor point 110 and each slave anchor point 140 are distributed in the same plane, or in different planes. The main anchor point 110 and each slave anchor point 140 can be arranged on different sides of the cabin as much as possible to cover a larger range.

[0052] The device for positioning a portable communicative device inside and outside the cabin of the second embodiment of the utility model can position the portable communicative device through at least three UWB and star flash hybrid anchor points inside the vehicle, which can cover a larger positioning range and has high positioning efficiency; compared with the first embodiment, the number of anchor points is greatly reduced, so the cost can be reduced.
