Claim One:
1. A method for electrically assisting with the propulsion of a rolling system comprising at least one driving wheel driven by an electric motor, the torque applied by said motor being a function of a propulsion torque transmitted by at least one user to said driving wheel, wherein said method comprises: a preliminary step of storing in memory an unknown input model representing said weighted system, which is a function of the geometry and of the mass of said weighted system, and having as output data the rotational speed of said driving wheel; a step of estimating said unknown input, the unknown input to be estimated being the total torque applied to said wheel, influencing said rotational speed, said total torque being estimated from said rotational speed by calculating the inverse model; the propulsion torque transmitted by the user being deduced from said total torque estimated on the basis of the other known torques that make up said total torque.
