Abstract

An actuating signal for actuating a solenoid valve in particular of a fuel injection valve of an internal combustion engine has an attraction phase and a holding phase. The attraction phase has a comparatively high current and a maximum permissible duration and the holding phase has a comparatively low current and a minimum permissible duration (MHD). It is proposed that the minimum permissible duration (MHD) of the holding phase depends at least temporarily on a setpoint overall duration (GAD) of the actuating signal.
