Zusammenfassung:A METHOD FOR SWITCHING ON AN INDUCTIVE LOAD, IN PARTICULAR AN IGNITION COIL (3),WHOSE CURRENT (I) IS INTENDED REPEATEDLY TO REACH A PREDEFINED VARIABLE END VALUE (IA) AT A RESPECTIVELY PREDEFINED VARIABLE TIME (TA), INCLUDES MEASURING THE TIME INTERVAL (TLL-TEL) BETWEEN THE SWITCHING-ON ACTION (TEL) AND REACHING AT LEAST ONE PREDEFINED INTERMEDIATE VALUE (11). THIS TIME INTERVAL (TLL-TEL) AND THE AT LEAST ONE PREDEFINED INTERMEDIATE VALUE (11) ARE USED TO CALCULATE THE ANTICIPATED TIME (TA-TE) FROM SWITCHING ON UNTIL THE END VALUE (IA) IS REACHED. A FOLLOWING SWITCHING ON ACTION IS CARRIED OUT AT THE CALCULATED TIME (TA-TE) BEFORE THE RESPECTIVELY PREDEFINED TIME (TA).(FIG 2)
