  • Patent number: 6862513
    Abstract: A method and an apparatus for regulating the speed of the low-? wheel as a vehicle starts from rest or accelerates on a road surface having adhesive friction values that differ between the left and right sides of the vehicle (split-?), the low-? wheel being braked by braking intervention when it has exceeded a defined slip threshold.
    Type: Grant

  • Patent number: 6829529
    Abstract: A method for providing traction control when starting off a vehicle on a road surface having different adhesive friction values between the right and left sides of the vehicle, the driven low-&mgr; wheel being regulated to a specified setpoint slip pre-control value by a braking intervention if spinning occurs. In order to improve driving comfort, the engine speed is adjusted to the particular standing start conditions. To this end, the engine torque actually required for starting off is determined as soon as the vehicle is set in motion and has exceeded a specified speed threshold, and the engine speed actually required for starting off under the given conditions is determined from this. From this in turn, a new, corrected setpoint slip value is calculated and the setpoint slip is abruptly reduced or increased from the setpoint slip pre-control value to the newly calculated, corrected setpoint slip value.
