Abstract: A discharge control unit causes a high voltage to be generated in a secondary coil by controlling an igniter unit so as to block a flow of current from a primary coil towards a ground side, and controls a spark plug so that electric discharge is formed between electrodes of the spark plug. An energy input control unit controls an energy input unit to input electrical energy to an ignition coil after start of control of the spark plug by the discharge control unit. A normal ignition control unit controls ignition of an air-fuel mixture in a combustion chamber only through control of the spark plug by the discharge control unit. A specific ignition control unit controls the ignition of the air-fuel mixture in the combustion chamber through control of the spark plug by the discharge control unit and through control of the energy input unit by the energy input control unit. A control unit performs ignition control by the specific ignition control unit until a first predetermined period elapses after a start-up condition of an engine is established, and switches to ignition control by the normal ignition control unit after the elapse of the first predetermined period.

Abstract: According to an ignition device, a first switching unit applies a voltage between electrodes of by spark plug by turning on/off energization from an on-vehicle battery to a primary coil. Further, a second switching unit applies a voltage having the same direction as a spark discharge generated by turning on/off the first switching unit between the electrodes of the spark plug by supplying electrical energy accumulated in a booster circuit into a primary coil. Accordingly, it is possible to greatly reduce a complexity of the on/off switching of the first and second switching units compared to a conventional technology.

Abstract: In an electronic control apparatus, a microcomputer stops its operation when a power voltage supplied from a regulator starts to fall. When a low voltage detection circuit detects fall of the power voltage, the microcomputer is reset immediately and a communication start detection circuit is permitted to output a communication start signal. It is also possible to maintain the microcomputer in a wait state until proceeding to a sleep mode, and proceed to a normal operation mode when a power-on start signal is changed to be active in a period of the wait state.

Abstract: A battery, an energy charge inductance, and a first transistor are connected in series in an ignition system. A primary winding and a second switching device are connected in series between the ground and a point between the energy charge inductance and the first switching device. A drive circuit switches periodically on and off the first switching device and the second switching device during multispark duration of the spark plug such that each switching device has a different switching status from each other. After the multispark duration, the drive circuit switches periodically on and off the second transistor with a short switching interval. The switching interval is set such that a relatively low voltage that almost causes a spark is impressed to the spark plug. An ion current detection is implemented by using this voltage as a power source.

Abstract: An ignition apparatus for an internal combustion engine is provided. The ignition apparatus includes an ECU. The ECU calculates a target value E* of an energy input amount of energy inputted into a spark plug based on an in-cylinder flow velocity v, a cylinder pressure P, and an air-fuel ratio AFR. The ECU also calculates a command value I* of a secondary current based on the in-cylinder flow velocity and control an operation of a second circuit according to the target value E* and the command value I*. The calculation of the target value E* using the in-cylinder flow velocity v, the cylinder pressure P, and the air fuel ratio AFR enables the energy input amount to be controlled according to the operating state of the internal combustion engine. The calculation of the command value I* based on the in-cylinder flow velocity v enables the secondary current to be controlled so as to eliminate a risk of the blowout of sparks. The ignition apparatus is, thus, capable of variably changing the amount of energy inputted to the spark plug to improve the fuel consumption.
