1. A method at a computing device, the method comprising:
receiving, at the computing device, sensor data for a vehicle providing vibration frequency and magnitude for a plurality of tests, along with a loading status for the sensor data for each of the plurality of tests;
calculating an energy (EL) for a low frequency passband and calculating an energy (EH) for a high frequency passband of a bandpass filter pair for each of the plurality of tests;
finding an energy ratio based on the energy for the low frequency passband and the energy for the high frequency passband for each of the plurality of tests, wherein the energy ratio (eRatio) comprises:
deriving weighting constants for a type of chassis of a vehicle; and
sending the weighting constants to a sensor apparatus at the vehicle for finding whether the vehicle is loaded or unloaded.
