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.

Method and control device for carrying out an emergency braking and/or panic braking of a vehicle

A vehicle braking system includes a brake pedal, a master cylinder, and an electronically-controlled booster having an input member and an output member adapted to provide an input force to the master cylinder that combines a driver-supplied input force and a boost force provided by the electronically-controlled booster. A wheel cylinder is fluidly coupled to an outlet of the master cylinder and operable to provide a wheel braking force proportional to the input force to the master cylinder. A pump is operable to pump fluid toward the wheel cylinder to provide an assisting wheel braking force. A controller is programmed to trigger a hydraulic braking assist routine in which the pump is activated to provide the assisting wheel braking force. The controller is programmed to reduce the boost force provided by the electronically-controlled booster during the hydraulic braking assist routine.
