Abstract
The present invention relates to a method for monitoring an ignition system, wherein the ignition system comprises a charge coil (L1) for charging the ignition system, a primary coil (L4) and a secondary coil (L5), said primary and secondary coils (L4, L5) being arranged to generate a voltage for spark generation, and a control unit (M1), characterized in the steps a) providing a separate coil (L3) adjacent to at least one of the charge coil (L1), the primary coil (L4) and the secondary coil (L5) b) using the control unit (M1) to monitor a magnetic flux at the separate coil (L3), and c) using information regarding said magnetic flux as input for controlling at least one property of an operation of the ignition system. The invention also relates to a control system for an ignition system.
