Abstract: A method for identifying a longitudinal jerking of a motor vehicle is provided, wherein a wheel speed of a driven wheel and a wheel speed of a non-driven wheel are recorded and wherein the longitudinal jerking of the motor vehicle is detected on the basis of a change in the measured wheel speeds. The detection of the longitudinal jerking is improved by comparing the change in the wheel speed of the driven wheel with the change in the wheel speed of the non-driven wheel in order to detect a longitudinal jerking as a result of a vibration stimulation in the drive train.

Abstract: A method and a device for supplying fuel to internal combustion engines comprise a regulated high-pressure system and a controlled low-pressure system, wherein an adaptation value for correcting the desired preliminary pressure is detected in an adaptation mode, in order to adjust a variable preliminary pressure in the low-pressure system. For this purpose, the preliminary pressure is specifically changed in the adaptation mode until vapor bubbles are detected by a regulator response of the high-pressure regulator of the high-pressure system. When vapor bubbles are detected, current process parameters of the fuel supply system are determined and the adaptation value is derived therefrom.
