ABSTRACT:
A process carries out an automatic braking operation in which, when the return speed of the accelerator pedal exceeds a threshold value and a transfer of the driver's foot from the accelerator pedal to the brake pedal is determined, an automatic braking operation is triggered. During that operation, a brake pressure is generated in the wheel brakes and is terminated when either a defined time has been exceeded since the triggering of the braking operation or when an operation of the brake pedal takes place by the driver. A support of the driver is ensured when operating the brake pedal in critical driving situations and a brake pressure buildup is carried out even before the operation of the brake pedal by the driver. After the automatic braking operation has been triggered, monitoring occurs to determine whether the time derivation of a quantity representing the operation of the brake pedal exceeds a threshold rise value. In such event, exceeding of the threshold rise value must take place within a defined time period after the triggering of the automatic braking operation, whereby the automatic braking operation is continued.
