Problems solved by technology
[0011] However, this known control device of an internal combustion engine poses a problem in that it takes time to restart the engine if the reset control for prohibiting fuel injection and ignition is performed for each cylinder under static start / stop
[0012] Although the crankshaft is turning in the normal direction, due to the fact that noise may be superimposed on the sensing signal, judging whether a circular motion in the reverse direction occurs at a single timing may perform reset for inhibiting fuel injection and ignition control, which increases the possibility of stopping the internal combustion, or in other words, of stalling the engine

Embodiment Construction
[0023] Embodiments of the present invention are described with reference to the drawings. Figure 1 to Figure 3 An example of a control device of an internal combustion engine according to an embodiment of the present invention mounted on a vehicle is shown.
[0024] exist figure 1 Among them, a control device 10 called an "engine control unit (ECU)" is installed in a vehicle together with an internal combustion engine for centralized control of the internal combustion engine. The control device 10 is configured such that a central processing unit (central processing unit, CPU) obtains a control program pre-stored in the memory through a reading operation, so as to perform control on the internal combustion engine according to various sensor signals and stored parameters.
[0025] Briefly, the internal combustion engine is a so-called reciprocating engine, in which the crankshaft 111 is rotated by the reciprocating motion of the piston originating from the ignition by the ig...

A device (ECU 10) for controlling an internal combustion engine which generates power by converting the reciprocating motion of a piston into rotation of a crankshaft 111, and the reciprocating motion is caused by the injection of fuel into a combustion chamber. The device comprises a crankshaft angular position sensor 131 for detecting rotation of the crankshaft in the opposite direction, a counter block 14 which counts up to increase the number of rotations in the opposite direction each time when the crank angle position sensor detects a rotation of the crankshaft in the opposite direction, and fuel injection- / -ignation control stop portion 15 which interrupts the injection of fuel into the combustion chambers and the ignition, when the counter block 14 counts up two consecutive times.
Description
technical field [0001] The present invention relates to a control device for an internal combustion engine, and more particularly to the control of the internal combustion engine when a circular motion of the engine in a reverse direction is detected. Background technique [0002] Internal combustion engines installed in vehicles are known. The internal combustion engine generates the driving force for moving the vehicle in the form of converting the reciprocating motion of the piston, which is injected directly into each combustion chamber or injected into the intake port of each combustion chamber, into the rotation of the crankshaft. Ignition and combustion of fuel. [0003] In an internal combustion engine, when a crankshaft rotates in a reverse direction for some reason, erroneous fuel injection and erroneous ignition may occur due to erroneous judgment regarding fuel injection timing and ignition timing. For example, according to static start / stop popularized in rece...
