A method, system, computer program and electronic control unit for estimating the weight of a vehicle, comprising the steps of, obtaining information relating to the acceleration of the vehicle and estimating the acceleration, estimating the force obtained from the engine, estimating the current number of wheels that are in contact with the ground, estimating the force needed to move the vehicle taking into account losses due to the forces needed to rotate the wheels based on the estimation regarding the current number of wheels that are in contact with the ground, estimating the force that is moving the vehicle by subtracting the estimated force needed to move the vehicle from the estimated force obtained from the engine, and estimating the weight of the vehicle based on the mathematical correlation that the weight of the vehicle is the quotient of the force that is moving the vehicle and the estimated acceleration. |
