International audienceWe present for the longitudinal control of an electrical vehicle a "model-free'' control strategy, which is illustrated by convincing experimental results. The physical control is a coefficient rate of the maximal voltage of the battery. The chassis and the engine dynamical equations exhibit complex unknown parameters and/or neglected terms. The proposed ``intelligent'' PI controller, which utilizes new algebraic techniques for estimating derivatives of noisy signals, permits to bypass those parameter and model uncertainties, without the necessity of identifying them
