Abstract:
A brake system for a motor vehicle having front and rear axles each supporting at least one wheel, said system comprising:an automatic braking force distribution controller controlling the distribution of braking force between the front and the rear axles on the basis of a difference value based on a rotational speed signal of the front and on a rotational speed signal of the rear wheels in accordance with a nominal difference value,a defect determination unit determining defects involving the rotational speed signals of the wheels of the motor vehicle,the automatic braking force distribution controller, in the event of a determination of a defect in a rotational speed signal of a front wheel and/or of a rear wheel, operating within the scope of an emergency operating procedure under exclusion of the defective initiating an emergency operating procedure under exclusion of the defective defective speed signal,in the emergency operating procedure the automatic braking force distribution controller controls the distribution of braking force between the front and the rear axles on the basis of a difference value based on a non-defective rotational speed signal of the front and on a non-defective rotational speed signal of the rear wheels in accordance with the nominal difference,with the sensitivity of the automatic braking force distribution controller increased by adjustment of said nominal difference to a smaller value.
