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.
