A method for operating a vehicle, the vehicle including at least one friction brake unit, including a brake body and at least one brake element, the brake body being rotatably fixedly connected to a wheel of the vehicle and the brake element being situated on the chassis side and being displaceable in the direction of the brake body. The brake element is pressed against the brake body for generating a friction braking action, and an actual vehicle parameter resulting from the friction brake action being monitored for vibrations with the aid of at least one sensor unit. When detecting a vibration, the frequency of the vibrations is compared with the rotational speed of the wheel, and at least one safety measure is carried out in a third step if the comparison indicates that the frequency is equal to or greater than the rotational speed of the wheel.

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 method for ascertaining a pressure-volume characteristic of a vehicle braking system includes determining at least a first pressure-volume value pair of a first pressure occurring in the braking system during a pressure rise and of a first volume displaced in order to produce the first pressure, deriving a second pressure-volume value pair for a second pressure higher than the first pressure or for a second volume greater than the first volume in consideration at least of the first pressure-volume value pair and an indication in a predefined characteristic curve of a volume difference between a first volume associated with the first pressure and a second volume associated with the second pressure, or of a pressure difference between a first pressure associated with the first volume and a second pressure associated with the second volume.
