Abstract

A method for specifying switching parameters of a solenoid control valve in a braking system of a vehicle includes stipulating a test vehicle acceleration and ascertaining at least two test pulse sequences. The test pulse sequences are each ascertained on the basis of the stipulated test vehicle acceleration and on the basis of switching parameter default values for the respective solenoid control valve, and the test pulse sequences have actuation pulses and adjoining nonactuation pulses. During an actuation pulse an activation of the respective solenoid control valve and during a nonactuation pulse a deactivation of the respective solenoid control valve takes place. The method further includes actuating the respective solenoid control valve using the at least two test pulse sequences in order to cause at least two test braking operations, wherein the respective test pulse sequence causes an alteration of a braking pressure at a service brake.
