The traction control increases stability, safety, efficiency and range of EVs preventing slippage in acceleration and permitting to use high-efficiency low drag tires. The performance of the presented approach is comparable with that obtained by the well-recognized techniques while this approach is simpler. This paper considers the longitudinal control of each driven wheel of the vehicle, and it bases the control on an adherence observer and a fuzzy controller of the adherence derivative. Numerical simulations as well as experimental verifications support the work. The experimental work was conducted by means of a test facility including the real time computation and actuation of the vehicle dynamic and of the adherence. The controller evidenced good tracking of the quasi-optimal set point in a very wide operating range without a priori knowledge of road conditions. Moreover, the experimental tests evidenced that the control has a good response to sudden changes in the adherence curve of the road.
