System and method for speed/traction/slip control by influencing a driving engine torque of the vehicle, the method comprising the acts of- Calculating an idealized nominal engine torque "w" from a linear control law applied to the speed/slip error.- Calculating an idealized setpoint for the speed/slip "v" by applying a reference model to the idealized nominal engine torque "w".- Calculating a linearizing feedback with properties∘ Compensating the nonlinearities in the road surface contact∘ Compensating the inertia in the powertrain∘ Damping the powertrainUsing for feedback- engine rotational speed- Numerically determined derivation of engine speed- Average speed of the driven axis- Numerically determined derivative of the rotational speed of the driven axis- Actual engine torque- applying the driving engine torque to the engine vehicle to influence the traction and stability of the vehicle.
