  • METHOD AND DEVICE FOR CONTROLLING SLIP IN A TRACTOR VEHICLE OR THE LIKE
    Publication number: 20110054750
    Abstract: A method and a device for controlling the slip of a tractor vehicle or the like, in which the drive wheel slip is determined and, if the actual slip is different from a specified nominal slip, the gear ratio of a controllable transmission in the drivetrain is adjusted in the direction of slip optimization. The transmission is a geared-neutral transmission whose output speed, at full drive power, can be adjusted to an extremely small value close to zero.
