A system for determining the mass of a vehicle includes a mass estimation module for estimating an approximate initial mass value for the vehicle and a force estimation module configured to determine a force value indicative of the force output from the vehicle powertrain. A mass determination module includes a recursive least squares module configured to perform in real-time a recursive least squares calculation based on the approximate initial mass value, the force value, and an acceleration value for the vehicle so as to provide a determination of vehicle mass. The mass determination module is further configured to receive a signal indicative of a user behavior event which indicates a change in the mass of the vehicle, and the mass determination module is configured to determine, in response to the user behavior event, a new approximate initial mass value for a subsequent recursive least squares calculation.
