The present invention concerns a method for estimating a mass and road load coefficients of a vehicle (1), including first and second rolling resistance coefficients and an air resistance coefficient, wherein estimates of the road load coefficients with values calculated on the basis of estimated road load forces (Frld) calculated using a first Extended Kalman Filter, and the estimate of the mass is updated with an average of values calculated using a second Extended Kalman Filter.
