controlling the brake booster, as a function of an actuation of the brake pedal, to generate a hydraulic pressure of the brake system;
monitoring the motor vehicle for a standstill of the motor vehicle;
monitoring an actuation path of the brake pedal for an exceedance of a specified limit value; and
activating a holding function for maintaining the hydraulic pressure present in the brake system when a standstill and a limit value exceedance are detected;
wherein, at least one state variable of the motor vehicle is ascertained, and the limit value is specified as a function of the at least one state variable.
