A method for vehicle mass estimation includes setting a vehicle mass value to an initial value and a driving resistance force value to an initial value, receiving at least a longitudinal acceleration value, driving/braking torque on each axle/wheel, and an angular wheel velocity value, and estimating a driving resistance force value based on the vehicle mass value and the angular wheel velocity value. The method also includes setting the driving resistance force value to the estimated driving resistance force value and determining a fuel level value and a seat occupancy value for at least one seat of an associated vehicle. The method also includes estimating, using the fuel level value and the seat occupancy value, a vehicle load value, and setting, based on the vehicle load value, at least one of a center of gravity value of the vehicle and a moment of inertia value of the vehicle.
