Abstract:
1. Anti-slip device for the drive wheels of a vehicle, in particular a motor vehicle, comprising: an active braking device for the drive wheels; a torque regulator that provides a control signal to the active braking device as a function of information on regulation deviations with respect to a specified wheel speed regulation setting, wherein the wheel speed regulation setting defines wheel speed settings corresponding to equal wheel adhesion; a control unit that provides the torque regulator with a regulation initialization information; wherein the control unit provides the regulation initialization information based on all-terrain travel parameters for the vehicle, including adhesion and drive wheel speed, terrain slope and/or; slant, and information about action taken by the driver on one or more vehicle control elements, wherein, in at least one operation phase of the vehicle, the torque regulator (i) selects a first drive wheel to brake, referred to as slow wheel, and regulates a speed of the slow wheel near a first wheel speed lower than the wheel speed regulation setting in order to obtain motive power, while (ii) simultaneously letting at least one other drive wheel participating in the traction of the vehicle not braked so that a speed of said at least one other drive wheel increases above the wheel speed regulation setting in order to increase road adhesion of said at least one other drive wheel.
