Patent ID: 7093913

Claim:
Method for traction control of slipping wheels of at least one driving axle, the wheels of the at least one driving axle are driven by way of an open differential gear and can be interlocked by braking intervention to a predeterminable degree for effecting a differential lock function, the method comprising the steps of: sensing a wheel slip of the wheels; comparing a sensed wheel slip variation with predetermined wheel slip patterns for detecting and monitoring a current driving condition; performing a braking intervention effecting the differential lock function when the sensed wheel slip variation is coincident with at least one predetermined wheel slip pattern; wherein the defined braking intervention includes an adaptive pressure reduction gradient or an adaptive pressure increase gradient is calculated on each individual wheel in dependence on the detected wheel slip pattern, and in that a pressure reduction or a pressure increase is realized by adapting pulse-pause valve actuation sequences; and wherein a pause between two pressure reduction pulses is determined as a function of a vehicle reference speed, the wheel slip and a constant base quantity according to the relation Δ T=T B −k 1 *ν ref +k 2 *λ fil where T B : base quantity k 1 , k 2 amplification factors ν ref : vehicle reference speed λ fil : wheel slip (filtered).
