Anti-skid device for the driving wheels of a vehicle and method for realising the same

Method of avoiding slippage of wheels of a vehicle, wherein the vehicle comprises a torque regulator that provides a control signal to an active braking device of drive wheels of the vehicle 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, wherein the method includes the following steps:

• providing a control signal to the torque regulator of the active braking device as a function of information on regulation deviations with respect to the wheel speed regulation setting;
• and
• providing a regulation initialization information to the torque regulator based on parameters for vehicle travel on the ground, including adhesion and wheel speed, terrain slope and/or slant, and information about action taken by the driver on vehicle control elements,
• in at least one operation phase of the vehicle:
• selecting a first drive wheel to brake, referred to as slow wheel, and regulating a speed of the first drive wheel near a first wheel speed lower than the wheel speed regulation setting in order to have drive power, while
• simultaneously letting at least one other drive wheel that participates in traction unbraked so that a speed of said at least one other drive wheel increases above the wheel speed regulation setting in order to eject foreign bodies reducing the adhesion of said at least one other drive wheel and use the rotational speed of said at least one other drive wheel to dig into the ground and reestablish adhesion.

Anti-slip device for the drive wheels of a vehicle, in particular a motor vehicle, comprising:

• a drive torque regulator that distributes a drive torque among drive wheels of the vehicle 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 drive 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 drive torque regulator (i) selects a first drive wheel to slow down, 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 regulating a speed of at least one other drive wheel participating in the traction of the vehicle so that the 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.
