Abstract

See full text

In a control apparatus, a discharge control unit controls an igniter unit so that a flow of current from a primary coil towards a ground side is blocked, thereby generating a high voltage in a secondary coil, and controls a spark plug so that the spark plug generates electric discharge. An energy input control unit controls an energy input unit so as to input electrical energy to an ignition coil after the start of control of the spark plug by the discharge control unit. A control unit and an abnormality detecting unit detects an abnormality in the igniter unit or the ignition coil based on a first threshold and a first current value that is a value corresponding to a current detected by a current detection circuit at this time, when a first predetermined period elapses after the start of control of the spark plug by the discharge control unit.
