Method of switching on an inductive load

摘要

A method for switching on an inductive load, in particular an ignition coil, whose current is intended repeatedly to reach a predefined variable end value at a respectively predefined variable time, includes measuring the time interval between the switching-on action and reaching at least one predefined intermediate value. This time interval and the at least one predefined intermediate value are used to calculate the anticipated time from switching on until the end value is reached. A following switching-on action is carried out at the calculated time before the respectively predefined time.
