Abstract
A device for controlling the wheel slip, particularly for controlling the brake slip and/or the drive slip of individual wheels for a motor vehicle, by which a braking pressure applied to the vehicle wheels can be varied and/or set as a function of the movement behavior of the vehicle wheels, having means for braking, particularly for locking, at least the front wheels and/or the rear wheels of the motor vehicle in the event a skidding condition is detected, the vehicle having wheel-speed sensors (5) whose signals contain information about the direction of rotation of the respective wheel, these signals being processed within the framework of a skid detection.
Claims6
A device for controlling wheel slip of individual wheels of a motor vehicle, comprising:
- sensors configured to generate signals containing information about rotation directions and speeds of respective wheels, the signals being processed to detect a skidding condition;
- a first structural arrangement to at least one of vary and set an applied brake pressure to a wheel as a function of a wheel movement behavior;
- and
- a second structural arrangement to brake at least one of:
- i) a set of front wheels, and ii) a set of rear wheels, if the skidding condition is detected;
- wherein the second structural arrangement is operable to prevent operation of brake-slip control from occurring if the skidding condition is detected.

- sensors configured to generate signals containing information about rotation directions and speeds of respective wheels, the signals being processed to detect a skidding condition;
- a first structural arrangement to at least one of vary and set an applied brake pressure to a wheel as a function of a wheel movement behavior;
- and
- a second structural arrangement to brake at least one of:
