Specifically, fig. 1 is a schematic flowchart of a method for automatically configuring a vehicle anchor point according to an embodiment of the present disclosure.
As shown in fig. 1, the vehicle includes a plurality of anchor points, and the vehicle anchor point automatic configuration method includes the steps of:
in step S101, a virtual coded address of each anchor point is acquired.
Further, in some embodiments, obtaining the virtual coded address of each anchor point comprises: identifying the level value of the control circuit corresponding to each anchor point; and coding each anchor point according to the level value of the control circuit corresponding to each anchor point to obtain the virtual coding address of each anchor point.
Specifically, as shown in fig. 2, a plurality of UWB (Ultra Wide Band, wireless carrier communication) anchor points are arranged on the vehicle according to the embodiment of the present application, such as anchor point 1, anchor point 2, anchor point 3, through anchor point N, a power management ECU (Electronic Control Unit), and a central computing module MCU (Micro Control Unit), where when arranging anchor points, it is required to ensure that hardware and software of each anchor point on the vehicle are the same, and hardware of each anchor point has at least 2 or more Control circuit interfaces, that is, the number of the Control circuit interfaces is determined by the number of the anchor points.
Furthermore, when the anchor point starts the positioning function, firstly, the level value of the control circuit corresponding to each anchor point hardware on the vehicle needs to be identified; secondly, the level value of the control circuit corresponding to each anchor point is coded through software on the anchor points, so that a virtual coding address of each anchor point, namely a hardware address of each anchor point is obtained.
In step S102, a plurality of anchor points are sequentially powered on the basis of a preset coding strategy and a virtual coding address of each anchor point, and when the anchor points are in an activated state, matching words of vehicle key signals are matched through the anchor points to obtain a matching result of each anchor point.
The preset encoding strategy may be an encoding strategy set by a person skilled in the art according to actual application of the vehicle, or an encoding strategy obtained through computer simulation, and is not specifically limited herein.
Specifically, in the embodiment of the application, firstly, a power management module sequentially supplies power to anchor points arranged at various positions on a vehicle according to a preset coding strategy and a virtual coding address of each anchor point; secondly, the central computing module MCU sends instructions to control the start and the close of the anchor points through the vehicle network bus, when the anchor points are in the start state, matching words of vehicle key signals are matched through the anchor points, and the acquired matching data and the virtual coding address of each anchor point are sent to the MCU of the central computing module to be processed by adopting a Time Difference of Arrival (TDOA) strategy, so that the matching result of each anchor point is obtained.
In step S103, based on a preset logical coordinate system, the logical coordinates of the vehicle key with respect to the plurality of anchor points are calculated according to the coordinates corresponding to the virtual code address of each anchor point and the matching result of each anchor point, so as to generate a control signal of the vehicle according to the logical coordinates.

Specifically, in the offline diagnosis process of the vehicle production line, the transmission data of any anchor point needs to be received from at least one remaining anchor point in the remaining anchor points, the distance diagnosis information of the at least one remaining anchor point is obtained based on the transmission data, and then the distance diagnosis information of each anchor point is collected by the central processing unit, so that a preset logical coordinate system is constructed according to the distance diagnosis information of the at least one remaining anchor point.
Further, in some embodiments, after obtaining the distance diagnostic information of the at least one remaining anchor point based on the transmission data, the method further comprises: judging whether the working state of at least one residual anchor point meets the preset working requirement or not based on the distance diagnosis information of the at least one residual anchor point; and if the working state of the at least one residual anchor point meets the preset working requirement, judging that the at least one residual anchor point is in a normal working state, otherwise, judging that the working state of the at least one residual anchor point is in an abnormal working state.

The preset work requirement may be a work requirement set by a person skilled in the art according to actual application of the vehicle, or a work requirement obtained through computer simulation, and is not specifically limited herein.
Specifically, after the distance diagnosis information of the at least one residual anchor point is obtained, a production line worker needs to check whether the working state of the at least one residual anchor point meets the preset working requirement through a large screen, if the preset working requirement is met, the at least one residual anchor point is judged to be in a normal working state, otherwise, the at least one residual anchor point is judged to be in an abnormal working state, and therefore the fault reason of the at least one residual anchor point is generated.
The fault reason of the anchor point may be a fault reason of hardware equipment of the vehicle itself, or a fault caused by an external objective condition, such as collision, aging, or the like, in a process of using the vehicle by a user, which is not specifically limited herein.
Further, as shown in fig. 3 and 4, a preset logical coordinate system is constructed according to the distance diagnostic information of each anchor point collected by offline diagnosis of the vehicle production line, based on the preset logical coordinate system, multilateral positioning is performed by the central processing unit according to the coordinate corresponding to the virtual coding address of each anchor point and the matching result of each anchor point according to the multilateral positioning principle of the mathematical formula nonlinear minimum second order method, and the relative position of the vehicle key from each anchor point, for example, the accurate position of 1 meter at the front door of the vehicle, 1 meter at the tail of the vehicle, 20 meters beside the vehicle, and the like, is obtained according to the logical coordinate of the vehicle key calculated by the central processing unit relative to the anchor points, and a control signal of the vehicle is generated according to the accurate position, so that a welcome function of automatically opening the door of the vehicle, automatically opening the trunk, and the like, is realized.
