METHOD FOR TEACHING SWITCHING PARAMETERS OF A SOLENOID CONTROL VALVE IN A BRAKING SYSTEM OF A VEHICLE, AND BRAKING SYSTEM

摘要

The invention relates to a method for teaching switching parameters of a solenoid control valve (9a, 9b, 10a, 10b) in a braking system (1) of a vehicle (3), comprising at least the following steps: defining a vehicle test acceleration; determining at least two test pulse sequences (PF1, PF2), each test pulse sequence (PF1, PF2) being determined in accordance with the defined vehicle test acceleration and in accordance with switching-parameter initial values for the solenoid control valve (9a, 9b, 10a, 10b) in question and the test pulse sequences (PF1, PF2) comprising actuation pulses and non-actuation pulses, activation of the solenoid control valve in question occurring during an actuation pulse and deactivation of the solenoid control valve (9a, 9b, 10a, 10b) in question occurring during a non-actuation pulse; controlling the solenoid control valve (9a, 9b, 10a, 10b) by means of the at least two test pulse sequences (PF1, PF2) in order to effect at least two test braking operations, a change in a brake pressure (pBa, pBb) at a service brake (5a, 5b) of the braking system (1) being effected by each test pulse sequence (PF1, PF2) in such a way that a change in the driving dynamics (w1, w2) of the vehicle (3) results; determining driving-dynamics change variables in order to determine the change in the driving dynamics (w1, w2) of the vehicle (3) resulting from the control with the corresponding test pulse sequence (PF1, PF2); and adjusting the switching-parameter initial values for the solenoid control valve (9a, 9b, 10a, 10b) in accordance with the driving-dynamics change variables in order to teach the switching parameters of the solenoid control valve (9a, 9b, 10a, 10b).
