Abstract
When at least one drive wheel is showing a tendency to spin, at least the torque of the drive unit of the vehicle is influenced so as to reduce the tendency to spin. The tendency to spin is recognized when the slip of at least one of the drive wheels exceeds a predetermined desired value, where this desired value is adjustable as a function of at least one operating variable. This minimum of one operating variable is associated with the drive power called for by the driver, and is based on at least one of gas pedal position and engine rpm. The desired slip is increased in the range of higher power demands to improve the traction.
