  • Method and device for controlling the traction slip of a vehicle with a high coefficient of friction
    Patent number: 6705685
    Abstract: A system for controlling the traction slip of a vehicle including identifying a start situation with a high coefficient of friction uphill or with a heavy vehicle load, and once the start situation is identified and traction slip prevails, reducing a brake control intervention and/or increasing the nominal engine torque.
    Type: Grant

  • System for controlling the traction slip of a vehicle
    Patent number: 6533367
    Abstract: A method for controlling the traction slip of a vehicle on a roadway with sidewise different coefficients of friction includes the following steps: identifying a driving situation on a roadway with sidewise different coefficients of friction and, when the driving situation is identified and traction slip is encountered on both wheels, decreasing the brake pressure of the driven wheel on the low coefficient-of-friction side. A device for controlling the traction slip of a vehicle on a roadway with sidewise different coefficients of friction includes a determining device for determining a driving situation on a roadway with sidewise different coefficients of friction, and a brake actuation control which decreases the brake pressure of the driven wheel on the low coefficient-of-friction side when the driving situation is identified and traction slip is encountered on both wheels.

  • Method and device for brake pressure adjustment
    Patent number: 6520601
    Abstract: The present invention discloses a method for brake pressure adjustment of a wheel brake comprising the following steps: determining a preliminary nominal pressure gradient in a brake control, determining actuating signals for a hydraulic pump and/or at least one hydraulic valve for the adjustment of the nominal pressure gradient, determining the actual pressure by way of a pressure model, determining the slip of a driven wheel, comparing the actual pressure with a first threshold value that is lower than the maximum possible brake pressure, and comparing the wheel slip, if the wheel slip is a traction slip, with a second threshold value, wherein, if the actual pressure and the wheel slip exceed the respective threshold values, the preliminary nominal pressure gradient is raised. The present invention also relates to a corresponding device.
