Abstract:
1. A method of controlling at least one valve of a brake circuit using an electrical control variable, the method comprising: providing a characteristic curve which characterizes a relationship between a pressure drop across the valve and the electrical control variable, the characteristic curve having at least one region in which a change in the electrical control variable results in a change in the pressure drop; and selecting a starting value for the electrical control variable during actuation of the valve such that the starting value is one of: (a) in the at least one region and (b) at a boundary of the at least one region; wherein the starting value in at least one regulating cycle is selected as a function of a value of a valve control variable in a previous regulating cycle; and wherein the valve control variable in a previous regulating cycle is a current through a coil in the valve which causes a brake slip of a wheel to exceed a predetermined value.
