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.

Method for operating a vehicle, vehicle

In a method for recovering energy in a braking process of a hybrid vehicle which has an internal combustion engine and an electric drive, as well as a hydraulic or pneumatic braking system, the exploitation of the electric drive is able to be optimized if the braking system includes at least one pressure reduction valve, using which the braking pressure exerted by the driver is able to be reduced as a function of the deceleration proportion of the electric machine.
