The present invention relates to a method at a sensor apparatus affixed to a transportation asset. The method includes calibrating the sensor apparatus by initiating a vertical impact at the transportation asset, measuring the spring oscillation and creating a model of the transportation asset. The method further includes detecting, subsequent to the calibrating, an impact event at the sensor apparatus. The method further includes measuring the spring oscillation due to the impact event at the sensor apparatus and using the measured spring oscillation in the model created during calibration to create a load mass estimate for the transportation asset. 一种在固定至运输资产的传感器装置处的方法。所述方法包括：通过在所述运输资产处发起垂直冲击来校准所述传感器装置，所述校准对弹簧振荡进行测量并且创建运输资产的模型。所述方法还包括：在校准之后，检测所述传感器装置处的冲击事件。所述方法还包括：测量由于在所述传感器装置处的冲击事件而引起的弹簧振荡，以及在校准期间创建的模型中，使用所测量的弹簧振荡来创建针对所述运输资产的负载质量估计。
