Abstract

In a method, which can be performed by a control device for carrying out an emergency braking and/or panic braking of a vehicle, in a first phase, a setpoint vehicle deceleration requested instantaneously by a driver is ignored and a motor of an electromechanical brake booster is operated in a predefined high power mode such that a main brake cylinder pressure in the main brake cylinder is increased; in an intermediate phase, the main brake cylinder pressure is reduced to a setpoint pressure by pumping brake fluid from the main brake cylinder into the at least one wheel brake cylinder and the motor force of the motor is reduced to a setpoint force; and the brake pressure increase in the at least one wheel brake cylinder is continued during a second phase only if the driver requests instantaneously a setpoint vehicle deceleration.
