Abstract
In various example embodiments, a system and method for determining a power of a vehicle is disclosed. A method includes: providing predetermined calibration settings relating force to engine 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 of the vehicle including vehicle load; determining the vehicle power based on the total weight and drag force of the vehicle; and transmitting the total power to a display.
