A braking system for a vehicle, which includes a control system configured to: actuate a pressure generation device in accordance with a braking request signal to generate the brake pressure; ascertain an operational state of the pressure generation device; ascertain a position of a displacement piston of a brake master cylinder based on the braking request signal; and couple a pressure modulation device to a brake master cylinder volume and actuate the device so that the pressure modulation device conveys brake fluid out of the brake master cylinder volume into the wheel brake circuit, if the operational status of the pressure generation device is ascertained to be nonoperational and the displacement piston is in the idle position.

Braking system for a vehicle and method for braking a vehicle

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

The invention relates to a control device () for at least one electromechanical brake booster of a brake system of a vehicle having an electronics device () that is designed to compare a provided sensor signal () relating to a differential path (d) between a valve body (), displaced by a controlled motor, of the electromechanical brake booster and an input rod () of the brake system with a specified normal value range, such that, if the sensor signal () relating to the differential path (d) lies outside the specified normal value range, the electronics device () is in addition designed to define a maximum limit value for a target quantity relating to a target motor torque to be carried out by the motor, at least taking into account the sensor signal (), in such a way that, at least during a specified time interval after the defining of the maximum limit value, at most an actual motor torque corresponding to the defined maximum limit value can be carried out by the controlled motor. The present invention also relates to an electromechanical brake booster for a brake system of a vehicle, to a brake system for a vehicle, and to a method for operating an electromechanical brake booster of a brake system of a vehicle.
