A method for conveying a metered hydraulic volume in a vehicle braking system by an electrically driven motor pump assembly, wherein a mechanical pump of the motor pump assembly is driven by an electric motor of the motor pump assembly. A rising motor voltage ramp is applied to the electric motor, a motor current being detected, and a conveying mode of the motor pump assembly starting as soon as a motor torque generated by the motor current exceeds a total of drag torque, breakaway torque and friction torque of the motor pump assembly. The motor current reduces when the conveying mode starts. The method is characterized in that, when a reduction in the motor current is detected after a specified time interval has elapsed, a motor voltage is reduced to a value which ends the conveying mode. The invention further relates to a vehicle braking system.
