Patent ID: 7711469

Claim:
A process for controlling the brake system of a motor vehicle with all-wheel drive, comprising: controlling at least one coupling unit with an electronic control unit, for engaging and disengaging a drive unit of the all-wheel drive; decoupling, under corresponding control of the at least one coupling unit, at least one wheel from the drive unit; performing one of holding and increasing a predefined brake pressure on at least one wheel of the motor vehicle, after a stop of the vehicle on a slope, in one of a dependent and independent manner relative to an extent of brake pedal actuation; further holding the predefined brake pressure during a brake pressure holding time until a brake pressure reduction condition is present; reducing at least temporarily, during the brake pressure holding time, the brake pressure on the at least one wheel; and for detecting slippage, maintaining decoupled the at least one wheel from the drive unit under corresponding control of the at least one coupling unit while at least another wheel remains pressurized with brake pressure
