Abstract:
1. A method for controlling a rotational speed of at least one rotating element in a vehicle's drive line, comprising defining a first control model and a second control model, calculating with the first control model a permitted slippage of at least one of the vehicle's ground-engaging elements at a point of contact of the ground-engaging element with the ground, which ground-engaging element is driven via the rotating element, calculating with the second control model a torque delivered to the ground-engaging element, and utilizing a result of one of the control models for controlling the rotational speed of the rotating element, wherein the first control model calculates at least one limit for the permitted slippage and the second control model is utilized for controlling the rotational speed of the rotating element, provided that a slippage at the point of contact with the ground, calculated using the first control model, lies on the permitted side of the limit.
