An EV (Electric Vehicle) with two independent front wheel propulsion system was presented. The dynamic model of the EV was developed and some simulation results were presented for different adhesion coefficients. In order to guarantee that the vehicle describes the desired trajectory, independently of the road conditions, a traction and a stability control systems were proposed. The traction control algorithm was implemented, and assures the limitation of the tire slip into the stable region. This control level enables the maximization of the traction force that can be applied to the road surface. The traction control is efficient when the road surface is homogeneous. However, when left and right sides adhesion coefficients are different, it is necessary to implement an additional control level. This second control algorithm works as a stability controller, adjusting the generated torque in each wheel drive, in order to guarantee the desired traction force applied to the road surface. Independently of the adhesion coefficients on left and right sides, the stability control algorithm inhibits wheel-spin and assures the steerability and stability of the vehicle.
