Abstract:
A method for improving the control behavior of an anti-lock control system of a four-wheel, two-axle vehicle, including the steps of:measuring rotational behavior of the vehicle wheels;deriving a vehicle reference speed;obtaining criteria for identifying a cornering situation and the direction of cornering from the rotational behavior of the vehicle wheels;instead of a standard control mode, putting into operation a special control mode when cornering is identified, said special control mode causing a reduction of braking pressure on at least one wheel of the group consisting of the front wheel on the inside of the corner and the rear wheel on the inside of the comer already in a partial braking range; andreducing the gradient of a braking pressure build-up on the at least one wheel in the partial braking range when a threshold value of a wheel speed difference is exceeded, which difference is the difference between the wheel speed sums per vehicle side formed from the speeds of the two wheels of each side of the vehicle, the reduction taking place in dependence on the extent by which the threshold value of the wheel speed difference is exceeded.
