Traction is broadly defined as the adhesive friction of a body on a surface on which it moves. A traction drive is a device in which torque is transmitted from an input element to an output element through nominal point or line contact typically with a rolling action by virtue of the traction between the contacting elements. While tractive elements are commonly spoken of as being in contact, it is generally accepted that a fluid film is present between them. Almost all traction drives require fluids to remove heat, to prevent wear at the contact surfaces, and to lubricate bearings and other moving parts of the drive. Thus, instead of metal-to-metal rolling contact a film of fluid is introduced into the contact zone and interposed between the metal elements. The nature of this fluid determines to a large extent the limits in performance and the capacity of the drive.

To improve the traction behaviour, one traction control per wheel is modelled, which is integrated into the control allocation approach. The aim of traction control is to prevent wheel spin while achieving maximum traction and driving stability. Slip is used as the control variable for traction control. Using the longitudinal slip sx and the lateral slip sy the combined slip scom is defined.
