Abstract: A method for detecting an error of an ignition coil of a vehicle is provided to exactly judge an electrical error of the ignition coil on the basis of output voltage of a primary side of the ignition coil generated according to the current flow of the ignition coil. A method for detecting an error of an ignition coil of a vehicle is composed of steps for receiving signals of each sensor, checking whether an error diagnosis condition of the ignition coil is satisfied or not, and monitoring voltage of a primary side of the ignition coil for the pre-set time(101,103,105,107); deciding that the ignition coil is normal if the voltage of the primary side input for the predetermined time is over a first pre-set value and below a second value(109,111); determining that the ignition coil is ground-shorted if the voltage of the primary side is kept at the second value or dropped from the second value to the first value, stopping the output of an ignition signal supplied to a power transistor, and then informing a driver of a ground short of the ignition coil(113,115,117,119); and determining that a fuse is disconnected by applying overload on the ignition coil, if the primary side is kept at the first value, stopping the output of an ignition coil signal supplied to the power transistor, and then informing the driver of an open error of an ignition coil line(121,123).

Abstract: In an ignition control system, a primary current control unit performs discharge generation control one or more times during a single combustion cycle. The discharge generation control allows a spark plug to generate a discharge spark. A parameter calculating unit successively calculates a parameter correlated with energy of a discharge spark. An energy density calculating unit successively calculates energy density that is energy per unit length of the discharge spark. When the energy density is greater than a predetermined value during a predetermined period after a primary current is interrupted during a single combustion cycle, an integrated value calculating unit calculates an integrated value by integrating the parameter during the predetermined period. The primary current control unit performs the discharge generation control again when the integrated value calculated by the integrated value calculating unit is less than a predetermined determination threshold.

Abstract: An ignition device includes a spark plug, a measurement value detector, an electrical breakdown determiner, an AC voltage applying section, and a first changing section. The measurement value detector includes primary and secondary coils, and detects at least one measurement value among an ignition coil, a primary current, a primary voltage, a secondary current, and a secondary voltage. The electrical breakdown determiner determines whether a discharge has become an electrical breakdown state based on the measurement value. The AC voltage applying section applies an AC voltage of a first predetermined frequency that causes voltage resonance to the primary coil. The first changing section changes the frequency of the AC voltage to a second predetermined frequency that can maintain the electrical breakdown state and is lower in frequency than the first predetermined frequency when it is determined that the discharge has become the electrical breakdown state.
