Methods for operating valves

Abstract

The invention relates to a method for actuating a valve with a solenoid valve drive through which an electric current (1) is conducted to open, close and hold the valve in an open position or in a closed position, The method has at least the following steps: a) receiving an opening signal, b) in response to the received opening signal, varying the current (1) conducted by the valve driver in the pattern of a first current signal (2) to open The valve, c) receives a closing signal, and d) in response to the received closing signal, alters the current (1) directed by the valve driver in the pattern of a second current signal (3) to close the valve , wherein the second current signal (3) has at least two changes of the current (1) separated in time from each other.

Description

Technical field

[0001] The present invention relates to a method for manipulating a valve having a solenoid valve driver, and current guides through a solenoid valve driver to open, closed valve, and hold the valve in an open position or closed position. In particular, the present invention can be used, for example, in, for example, current control of the feed valve of the ABS system, TCS system, ESP system, and / or IPB system. Here, the abbreviation ABS represents the anti-lock brake system, TCS represents the traction control system, and ESP represents the electronic stability program, and IPB represents a set of power brakes. Background technique

[0002] The feed valve of the ABS system or ESP system is typically run in a so-called switching mode or in a so-called (pressure difference) adjustment mode. Here, the switching mode is characterized by a short-time full stroke and (pressure differential) adjustment mode is characterized by partial strokes related to volume flow. ...
