Abstract
The invention relates to a method for determining an amplitude A of a pump-induced fluid pressure fluctuation of a fluid which is regulated to a desired fluid pressure pby means of a pump. In this case, the method comprises providing (S) a pressure signal of the fluid, determining (S) the amplitude A of the fluid pressure fluctuation on the basis of the pressure signal which has been provided, checking (S) whether the pressure signal which has been provided satisfies a predetermined plausibility criterion, and outputting or rejecting (S) the determined amplitude A on the basis of whether the pressure signal which has been provided satisfies the predetermined plausibility criterion. This advantageously provides a combined method in which, in addition to fundamentally determining the amplitude A of a fluid pressure fluctuation, a plausibility check is also carried out immediately in order to determine whether this fluid pressure fluctuation also actually corresponds to a representative value for the current system state. Furthermore, the invention also relates to a device which is designed to carry out the above-mentioned method and to a motor vehicle having a corresponding device.
