A process for the actuation of a solenoid valve, as well as computer program and tax - and / or closed-loop control device

摘要

A drive signal for the actuation of a solenoid valve, in particular of a fuel - injection valve of an internal combustion engine, has a pickup phase and on a holding phase. The pick-up phase has a comparatively high current and a maximum permissible duration and the holding phase, a comparatively low current and a minimum permissible duration (mhs) on. It is proposed that at least at times, the minimum permissible duration (mhs) of the holding phase of a desired - total duration (gad) of the control signal depends on.
