A system for determining a vehicle direction includes: an active wheel speed sensor (aWSS); an exciter ring for inducing a change in the signal from the aWSS; and a controller. The controller receives a first series of signals from the aWSS, compares them to an array of predefined signals, and determines a direction of travel based on the first series of signals matching the array. The controller receives a second series of signals from the aWSS and determines that the exciter ring has an anomaly in response to at least one of the second series of signals having a first difference. The controller updates the array of predefined signals to include a representation of the first difference to create an array of updated signals. The controller determines a direction of travel based on a latter series of signals matching one of the array of predefined signals and the array of updated signals.

    一种用于确定交通工具方向的系统包括:有源车轮速度传感器(aWSS);励磁器环,其用于引发来自aWSS的信号的变化;以及控制器。所述控制器从aWSS接收第一系列的信号,将它们与预定义信号的阵列进行比较,并且基于所述第一系列的信号与所述阵列匹配来确定行进方向。所述控制器从aWSS接收第二系列的信号,并且响应于所述第二系列的信号中的至少一个信号具有第一差异而确定励磁器环具有异常。所述控制器将预定义信号的所述阵列更新成包括所述第一差异的表示,以创建更新信号的阵列。所述控制器基于后一系列的信号与预定义信号的所述阵列和更新信号的所述阵列中的一个匹配来确定行进方向。
