The present disclosure provides trilateration with ultra wide band anchors. A computer includes a processor and a memory, and the memory stores instructions executable to: determine a currently activatable feature on a vehicle from a plurality of features; establishing a negotiation between each of a plurality of ultra wide band (UWB) anchor points of the vehicle and at least one mobile device; selecting a search strategy based on the current activatable features; upon selection of the search policy, during a search iteration, determining distance data from a subset of UWB anchor points to at least one mobile device, and inhibiting the remainder of the UWB anchor points other than the subset; performing trilateration on the distance data for the mobile device; and actuating a component of the vehicle based on a result of the trilateral calculation according to the currently activatable feature.
本公开提供“利用超宽带锚点的三边测量”。一种计算机包括处理器和存储器,并且所述存储器存储可执行以进行以下操作的指令:从多个特征中确定车辆上的当前可激活特征;在所述车辆的多个超宽带(UWB)锚点中的每一者与至少一个移动装置之间建立协商;基于所述当前可激活特征选择搜索策略;在选择所述搜索策略后,在搜索迭代期间,确定从UWB锚点的子集到至少一个移动装置的距离数据,并且禁止所述UWB锚点中的除所述子集之外的其余部分;针对所述移动装置对所述距离数据执行三边计算;以及根据所述当前可激活特征基于所述三边计算的结果来致动所述车辆的部件。
