Abstract: Misfiring in an engine cylinder can be detected based on the pressure therein as sensed by a pressure sensor with a high degree of reliability at any time even if the output signal of the pressure sensor contains an offset component superposed on a pressure component representative of the actual cylinder pressure. In one form, the pressure sensor output is differentiated to eliminate the influence of the offset component and then processed to generate a power stroke pressure information signal in the form of the time of a pressure-change peak in the differentiated pressure sensor output or an integrated value of the differentiated output, which is then compared with a threshold so as to determine whether misfiring took place in the cylinder. In another form, the offset component is calculated based on the pressure in the cylinder at two different crank angles during a compression stroke, and it is then removed from the pressure sensor output and compared with a threshold or it may be integrated for a prescribed crank angle range around TDC before comparison with the threshold. In a further form, an expected pressure in the cylinder at a third crank angle during a power stroke is calculated based on the cylinder pressures at first and second crank angles during a compression stroke preceding the power stroke, and then compared with the cylinder pressure as sensed by the pressure sensor at the third crank angle for misfiring determination.

Abstract: An engine control apparatus can significantly improve reliability in misfire detection by preventing erroneous detection of the level of an ion current due to noise superposition. An angular position detector generates a reference position signal representative of a predetermined crank angle of each engine cylinder in synchronism with the rotation of an internal combustion engine. Sensors detect an operating state of the engine. An ion current detector detects an ion current in at least one of the engine cylinders. An engine control parameter setter sets a control parameter for the engine in accordance with the reference position signal and the engine operating state. A misfire detector generates a misfire detection signal indicative of occurrence of misfiring in the at least one engine cylinder on the basis of a value of the ion current. The control parameter setter corrects the control parameter on the basis of the misfire detection signal. Alternately, the engine control apparatus may include a window setter for causing the misfire detector to determine misfire only when ignition coil is in a non-energized state.

Abstract: A control apparatus for a vehicle equipped with an engine senses a condition indicating the capacity of the battery of the vehicle. When the capacity is below a prescribed level, the drive current to an actuator of the vehicle is adjusted to prevent the battery from becoming excessively discharged. In one form of the invention, the drive current is decreased to decrease the load on the battery. In another form of the invention, the actuator is controlled to increase the engine speed, thereby increasing the output of a generator driven by the engine. In another form of the invention, the actuator is controlled to stop the engine. When the engine is restarted, the initial rotational speed of the engine is high enough for the generator to recharge the battery.
