A method for controlling the switching time of a switching valve, as well as on / off valve

摘要

The invention relates to a method for controlling the switching time of a switching valve, which can be used in an internal combustion engine. In a first step comprising, a heat is determined, which represents a quantity of heat, which is produced on at least one heat source, wherein between the heat source and the switching valve is a heat. The heat source is, for example, the waste heat generating electric coil of the switching valve, a frictional heat generating component of the switching valve, a compression heat generating high pressure chamber and / or an ambient heat supplies the environment of the switching valve. In the next step, an input variable (u) formed, which is fed to the heat source side of the total heat quantity represents heat transfer-track. A system model is provided in which the input variable (u) is fed and which a the temperature of the switching valve, which represents the output variable (y) supplies. Finally, the rules of the switching time of the switching valve, taking into account the output variable.n="12"
