[0028] figure 1 A current curve 4 according to the prior art is shown schematically. according to figure 1 , showing the variation of current 9 with respect to time 10 . For a further description of the current curve 4 , reference is made to the above-described embodiment of the prior art.

[0029] figure 2 The current curve 4 produced in the method according to the invention for actuating at least one solenoid valve in a valve arrangement having at least two different types of solenoid valves is shown schematically. also according to figure 2 , showing the variation of current 9 with respect to time 10 .

[0030] exist figure 2 As can be seen in the figure, the current curve 4 generated in the method according to the invention is split into, for example, an actuation time 2 which is short compared to the full actuation time 3 and a (immediately) subsequent full actuation time 3 . The actuation time 2 is predetermined here and is, for example, 15 ms. During the (ent...

Abstract

The invention relates to a method for actuating at least one solenoid valve. The method comprises at least the following steps: a) identifying the valve actuation signal, b) for a specific actuation time (2) immediately following the recognition of the valve actuation signal, using a specific constant control current (1) for the at least one The solenoid valve is energized, c) for the full control time (3) immediately after the control time (2), the control current is increased to the full control current (11), where the specific constant control current (1) and the control time ( 2) Arranged so that at least two different types of solenoid valves can be at least partially opened by the control current (1) during the actuation time (2).

Description

technical field [0001] The invention relates to a method for actuating at least one solenoid valve in a valve arrangement having at least two different types of solenoid valves. The invention can be used in particular for the current actuation of solenoid valves of, for example, ABS systems, TCS systems, ESP systems and / or IPB systems. Here, the abbreviation ABS stands for Anti-lock Braking System, TCS stands for Traction Control System (Drive Skid Control), ESP stands for Electronic Stability Program, and IPB stands for Integrated Power Brake (Integrated Power Brake). Background technique [0002] In principle, solenoid valves are used as technical components to control the inlet and / or outlet of gases or liquids, or to control or regulate the direction of flow. Especially with regard to solenoid valves used in motor vehicles, for some time from now an aim will be made to open these solenoid valves as quietly as possible. However, the problem that often arises here is tha...
