    • A vehicle system includes a first sensor and a second sensor, each having, respectively, different first and second modalities. A controller includes a processor configured to: receive a first sensor input from the first sensor and a second sensor input from the second sensor; detect, synchronously, first and second observations from, respectively, the first and second sensor inputs; project the detected first and second observations onto a graph network; associate the first and second observations with a target on the graph network, the target having a trajectory on the graph network; select either the first or the second observation as a best observation based on characteristics of the first and second sensors; and estimate a current position of the target by performing a prediction based on the best observation and a current timestamp.
    • 车辆系统包括第一传感器和第二传感器,每个具有不同的第一和第二模态。 控制器包括处理器,其被配置为:从第一传感器接收第一传感器输入和从第二传感器输入的第二传感器; 分别从第一和第二传感器输入端检测,同步,第一和第二观测值; 将检测到的第一和第二观测项目投影到图形网络上; 将第一和第二观察结果与图形网络上的目标相关联,目标在图形网络上具有轨迹; 基于第一和第二传感器的特性,选择第一或第二观察作为最佳观察; 并且通过基于最佳观察和当前时间戳执行预测来估计目标的当前位置。
