Abstract
In various example embodiments, a system and method for determining a gross combined weight of an electric or hybrid vehicle and its load is disclosed. A method includes: providing predetermined calibration settings relating engine drive force to engine speed and electric motor drive force to motor speed for a vehicle travelling at various speeds, altering accelerometer data based on filtered vehicle pitch and roll data, determining that one or more vehicle performance parameters fall within a threshold range, storing a plurality of data pairs that include longitudinal acceleration and drive force, and determining a slope of a line that linearly approximates the plurality of data pairs, the slope indicating a total weight, the total weight comprising a weight of the vehicle and a weight being hauled by the vehicle; and transmitting the total weight to a display.
